THE MULTIDUTY MOTOR (MIVAR) This brushiess motor (6) has a very high efficiency (from 0.8 to 1.2 amp. consumption at 12 volts to drive the camera at 20C (68 F) and has permitted a weight reduction not only in the camera but also in the battery (37) - page 12 - which weighs only 640 grammes enabling one hour of filming between recharges, i.e. eight to ten 60 m magazines. The incorporated electronics (7) control the sync. speed by crystal ; changing from 24 to 25 f.p.s. or vice-versa is made by shifting switch (38) so that the white spot mark is adjacent to the desired speed. Others speeds : 8.12.50 and 75 are obtained by setting the engraved button 35 accordingly. The MIVAR will stop the camera automatically in viewing position, i.e. the mirror being in the aperture axis allows the cameraman to frame and focus without loss of time. See pages 24 and 30. The motor will only operate when it is attached to the camera. The lamp (47) on the motor lights up until the marked speed is attained. In the event of speed reduction (flat battery for

THE 60 m MAGAZI N E The two chambers of this snap-on coaxial magazine are separated by a median partition and are connected by a light tight ramp for the passage of the film from the feed side to the take-up side (Fig F). THE 120 m MAGAZINE Bearing in mind the versatility and light weight of the 60 m magazine which can be changed almost instantaneously, there are occasions where a long take in excess of 60 m is required and for this purpose a 120 m capacity magazine is available. This co-axial magazine retains all the characteristics of simple threading and snapon action for which the Eclair equipment is famous.

THE HAND-GRIP The portability of the ACL is increased by the use of the hand-grip (36) supplied with the camera. Adjustable in the horizontal and the vertical plane, it permits the choice of the most confortable position. It can be screwed either under the camera base or on the right hand side of the camera (fig K). To carry the camera, the hand-grip (36) with its knurled knob (79) - fig. QR - can also be screwed on top of the camera head. MOUNTS AND LENSES The ACL has been designed to accept C mount lenses (fig Q, the mechanical back focal distance of which are 17.52 mm, and also other professional mounts such as Eclair CA (fig M) Arriflex, Nikon, etc. the mechanical back focal distances of which are greater than 17.52 mm.

GENERAL INFORMATION
REFLEX SIGHT The reflex image is obtained with an oscillating mirror (14) moving at half camera speed, which transmits the image formed by the lens onto the ground glass during the descent of the film. The viewf inder (focussing tube) is a new mechanical /optical realization which gives an exceptionally bright image. As on the Eclair 16, the ground glass gives a field of view greater than the recorded image, which eliminates the possible intrusion of microphones, etc. into the recorded picture. (Fig Q). This viewfinder - 10 x enlargement can be used for left eye or right eye viewing it can pivot through 360' parallel to the camera thus allowing the cameraman to frame and to focus in the most comfortable conditions whatever the position of the camera; for example, he can shoot with his back facing the subject. The eyepiece is adjustable of 5dioptres. The standard ground glass is engraved with the 16 mm frame (10,2 x 7,4 mm), the TV frame and a cross in the centre (UER standard). Gelatine filter holder Each ACL is equipped with a gelatine holder 2 (Fig A and R) which is located between the C mount and the reflex mirror close to the rear element of the taking lens. Its advantages are : It is not necessary to change filter at each lens change. It is possible to check the presence and type of gelatine through the viewf inder. It eliminates the requirement for front glass filters for each lens diameter, the price of which is very high compared to that of gelatine filters which are readily obtainable. Its position, away from the fi I m plane ensures any small dust or finger marks on the gelatine that may occur are out of focus on the final result and rarely visible. Shutter Contrary to reflex cameras in which the mirror mounted at 45' acts as a shutter, the ACL has a plane shutter of large diameter completely independant of the mirror (14). It is placed very close to the film plane with an opening of 175'. Cutting the image in the direction of the smallest dimension gives a perfect exposure, maximum definition and reduction of jerky effect on some panning shots. The exposure time is 1 /51 of a second at 25 frames per second and 1 / 49 of a second at 24 frames per second (page 33).

Fig. Q
Mechanism The complete silent mechanism is mounted on the mechanism plate which greatly reduces the time required for the normal overhaul and cleaning which we would strongly recommend to be carried out by one of our agents. The claw movement (13) is controlled by an excentric and a fixed cam (39), the security is ensured by a counter-cam. The four drive shafts run in selflubrificated bearings and the camera mechanism should NEVER be oiled. As already indicated page (4), the aperture plate of hard chromium-plated steel has, on the left, a fixed guide (11) which is the edge reference for the film and a spring loaded guide (12) on the right, which maintains the film against the fixed guide. The two guides (29-30) fig B position the magazine nose onto the mechanism plate.

Fig. S

Exposure indicator The ACL camera had to have a very safe Exposure Indicator device because of the professional work it must ensure. It could not be question of an ordinary photocell system due to the fragility of moving parts; on the other hand, a 100% automatic device leaves the cameraman no change of artistic creation. The basic idea is to leave the cameraman freedom to determine the exposure of the film and thus give him the possiblility of working according to his own technique; in other words he must have the possibility of
adjusting the diaphragm if he needs a special effect by under or over exposure, e.g. contrast. Before filming, the operator sets the exposure indicator with the aid of his professional photo- cell exposure meter indicating the diaphragm opening (stop) of the lens; it gives him a reference lighting intensity EO. The camera being connected to the battery, he adjusts the sensitivity potentiometer (34) so that only the middle diode EO, visible in the viewfinder, lights up. Thus the camera is now matched to the exposure meter.
During filming, if the lighting intensity of the subject varies, the control diodes visible in the viewf inder will be seen light up either + or. The operator wiII then correct the diaphragm of his lens so as to maintain the lighting intensity on the film to a value of EO, if he deems it necessary.
ELECTRONIC BASE 150 E This unit (8) forms a flat base for the camera body and consists of: 1 Jaeger socket (19) for power supply to the camera. 1 Sliding on/off switch (32) at the front part. 1 Cannon socket (33) for the accessory power supply. The stabilized 5 volt supply. 1 Souriau socket for electrical connections with the camera head. 1 sensitivity potentiometer (34) for adjustment of the exposure indicator. 1 Clapper switch (20). This flat base is provided with the standard congress 3/8 tapped hole for tripod mounting or hand- grip mounting (36).

PILOTONE MODULE

Fig. X

Magnetic recorder side

Fig. Y
The ACL servo-control led crystal motor allows the shooting of sync. sound without any cable connection between the camera and the tape recorder if the latter is equipped with a crystal controlled motor (e.g. Nagra 4, Perfectone E P 6 A2, Stellavox). Such a system (diagram KL) does not permit the use of the clapper. If, however, the two units Camera and recorder are connected by a cable, the clapper will function (diagram L M). See additional information page 29 for connection and use. When the recorder has no crystal, the synchronization can be ensured by using the Eclair pilotone- module (option) which contains its own signal. THE ECLAIR PILOTONE MODULE is contained in a metal cover. Its size: 92 x 66 x 23 mm is slightly larger than a packet of 20 cigarettes (fig. Y and Z). it is a crystal pilot f req uency generator 50-60 and 100 H Z.

DIOPTRY ADJUSTMENT OF THE VIEWFINDER
Legend of the external parts of the viewfinder: Ll - Eyepiece with shutter and rotatable rubber eyecup. L2 - Control ring of eyepiece shutter. L3 - Locking knob of the dioptry adjustment ring. L4 - 360' rotatable viewf 1 nder unit. L5 - Eyepiece support with rocking motion for left and right eye sight. L6 - Locking ring of the rotation of the eyepiece support. L7 - Adjusting ring for partial positioning of the ground glass image. L8 - Clutch for final adjustment of the ground glass image. Everyone having a different keenness of sight, it is necessary for the camera user to set exactly and then lock the dioptry adjustment which corresponds to his vision. This can be done with or without lens mounted on the camera. Adjustment with a lens: 1. Place L5 to the right or to the left according to the eye you normally use. 2. Make sure that the reflex mirror is in the front of the aperture, if not, turn knurled button 31 which controls the motor axle (see page 24, par. 5) 3. Turn control ring L2 to open the eyepiece shutter. 4. Focus the lens on infinity. 5. Diaphragm wide open or slightly closed to darken the ground glass. 6. Loosen knob L3 and turn slowly in one way and in the other the dioptry control ring until the frame and cross engraved on the ground glass are perfectly sharp. 7. Take note of the number of dioptries in + or - that corresponds to your sight. Lock the dioptry control ring in that position by tightening the button L3. This setting should always be kept as it will permit you to focus sharply at any distance.

Fig. PQ

GELATINE HOLDER
Adjustment without lens : Direct the camera towards a well lighted part (sky, for example) and follow the preceding instruction 1-2-3-6- and 7. Instruction for use Position L5 for your left or your right eye, as needed. Make sure the dioptry adjustment is correct and the button L3 is perfectly tightened. If the image on the ground glass is not optically horizontal, turn ring L7 in one way or the other to level the image. If you.come to the thrust before the image is in the right position, turn L8 in the reverse way and move again L7. Once the image has been so erected the viewf inder can be pivoted through 3600, a Wollaston prism will keep it in the correct position. If you shift L5 from left to right or viceversa the image will reverse gradually until it is up side down; just turn L8 to declutch L7 and turn same to reset the image to its normal position. A positioning "clic-stop" is provided in L6 to set the eyepiece Ll in horizontal and vertical positions. Fitting a gelatine to the holder Pull out the gelatine holder Open the holder by pressing the button (27) Place a 2" margin (5Ox5O mm) gelatine in the holder and close it. Cut the gelatine closely to the shape of the holder with a razor blade. Replace the holder in the camera, chamfered side forward. The correct positioning of the holder can be verified by checking that the aperture is concentric with the C mount aperture. NB. Never place more the one gelatine in the holder. Always film with the holder in place (with or without a gelatine) to avoid the possible fogging of the film. The fact of filtering behind the rear element of the taking lens may cause a slight alteration of the focussing distances engraved on the lens which will be automatically compensated if focussing is done through the reflex viewfinder.

FITTING THE HANDGRIP

Under the camera : Screw the handgrip support - Fig. QR into the electronic base using the knurled ring (27) Fix the handgrip (36) in the hole (80) of the support. Loosen the ring (79), set the position of the handgrip and tighten the ring (79). Loosen the half-moon (81), set the handgrip at the desired angle and retighten lock (81). Onto the right hand side of the camera: Fix the handgrip (36) to the side support (75) and lock it in the best position by means of lock (81). NB. The unit (79-80) - Fig. QR - is not used in this case.

FUNCTIONS OF THE ELECTRONIC BASE 150 E
a) On/off switch (32) This is a double action switch : it puts under tension the diodes of the exposure indicator, without starting the camera. Or it sends the power supply to the motor to start the camera. tee page 24 detailed instruction. b) The clapper switch (20) In the central position this switch provides no clapper. In outside right position : the clapper is automatic and provides fogging of the film for 0,3 secondes at each start. In inside left position : the clapper functions (0,3 seconds) at every manual pressure when the camera is running; this allows, for example, to clap at the end of filming, before switching off the motor.

Schema UV

Thus, the clapper ensures two functions - Automatic fogging of the film during 0,3 seconds at each start of the camera or manually at any moment. 20 - The supply of an 8 volt signal to the battery during 0,3 seconds (bloop) if the pilotone module is connected to the battery and the recorder, the signal triggers a 1 Kc signal on the recording tape. c) The running signal: A 12 volt signal available from the Jeager socket supplies the pilotone module and ensures that the module only produces a 12 volt signal when the camera is running. This signal can also be used to start a sound recorder from a distance.

d) The output signal : 1 - Tachometric signal This 3,8 volts square signal (peak to peak) is supplied by the motor. Its frequency is given by the motor speed multiplied by 40, that is to say 1000 Hz for 25 images per second and 960 Hz for 24 images per second. This signal directly supplied by the motor can be used for various purposes after it has been divided. 2 - Crystal signal (for MIALA motor only) : This is a 100 mV sine signal (peak to peak). Its frequency is 1024 KHz for 25 frames per second and 983.04 KHz for 24 frames persecond.

LOADING THE FILM
60 meter (200 ft) magazine: To load a film on a 2" (50 mm) core, proceed as follows: Feed side (fig. XY) (to be done in a dark room or in a changing bag) Put the magazine on its side, nose to the left. Depress the safety lock button and turn the lid catch anti-clockwise; lift the part of the latch that projects over the edge of the magazine. At the same time pull the lid backwards to clear it from the magazine. Lift the counter arm (53) which locks up utornatically. Holding the film reel in the left hand position, feed the end of the film (about 30 cm) between the two rollers at the entry of the guide (54). Note: the emulsion must be towards the exterior of the magazine between these rollers. Push approximately 15 cm (6") into the guide. Place the core onto the support f lange (55). Replace the Iid: insert the spring strip, at the left of the lid, into the magazine body (56), push the lid down and forward to locate it in the body and turn the lid catch clockwise to lock the lid. The counter arm (53) drops into place automatically as its catch (57) is released by the Iid. Take-up side (fig. YZ) (this can be loaded in, preferably in the shade) Turn the magazine and lay it on its side with the nose (58) to the right. Remove the lid. Pass the film between the rollers (59) and (60) and place the end into the upper film guide (61) of the nose; if necessary press on the pressure guide (62) to aid the entry. Pull the film through sufficiently to introduce it into the lower film guide (63). Pull 50 cm (20") of film into the magazine.
Open the two guide shoes (64-67) by pressing simultaneously the two catches (65). Place the film behind the two rollers and between the sprocket (66) and the upper guide shoe; make sure that the sprocket teeth are perfectly engaged in the perforations. Close the upper shoe toward the sprocket; it locks automatically. Place the film between the sprocket and the lower shoes (67); adjust the loop size by pulling the film upwards outside the magazine until the loop is level with the magazine locking tongues (68). This is important.
Close the lower shoe (67) against the s procket and divide the film equally over and under the film separator (69) in the magazine nose. Wind the film onto the core and place it on the flange (70). This flange is interchangeable with flange (55). Replace the Iid. Note: the S part is an audible warning unit (see page 25).
Loading a daylight loading spool to the magazine Choose a shaded area if possible. Pull and lift vertically the flange catches (71) on the supply and take-up sides. Remove the flanges (70). Load the film as for a core load. Lock the spools in place with the catches (71) ensuring that they are pushed firmly home. NB. In order to ensure the lowest noise level check that the spools are not warped and that they are firmly locked onto the axle as indicated above. If it is not intented to use the magazine at once, place the protector on the nose. The counter (72) As already noted, the counter arm comes into operation automatically. The pointer (73) indicates the amount of unexposed film remaining; a red portion of the counter dial indicates the imminence of the end of film. 120 m (400 feet) magazine: Loading the 120 rn magazine in dark room on a 2" (50 mm) core: Supply side Place the magazine, flat on a table, nose (58) to the left. To remove the I id, press on button (83) and turn downwards the white lock (84) for about 20 mm. Lift slightly the rear part of the lid and pull it to the right to disengage the spring which maintains the front part of the I id to the nose. Load the film according to the information given for the 60 rn magazine.

EXPOSURE INDICATOR
This being temperature compensated (-25 to + 60C) the setting remains constant for several weeks. The measuring system and display assembly is situated immediatly next to the ground glass, supporting the viewfinder frame (fig. T). A resolving prism (01) which is semiref lecting is stuck to the prism block (02) and ref racts part of the I ig ht rays emerg 1 ng from the ground glass towards the photo resistive element (03). The light intensity received by the photo resistive element is compared with the reference determined by the gauge, and intensity already memorised by the computer (fig. U). The seven diodes are mounted on a ceramic base situated next to the ground glass, outside the field of view (fig. T); they indicate the zero or the difference in aperture (either + or The maximum recordable difference is 1.5 stops, each diode representing about one half stop (fig. U).

Advantages of the system Compactness of the measuring assembly and display situated next to the ground glass This lay out requires the minimum of optical components, no reflection, no intermediate optics, (no risk of misalignment). System of setting up by comparison No setting imposed by the manufacturer, the operator is the judge of the optimum fighting for the film. No variable density disc, no compensation for non-linearity of the CDS cell respose. No corrections to be made on the sensitivity adjustment in spite of ageing and the history of the CDS cell. Application of LED: Unlimited life for the whole unit (even when subjected to heftier shocks that is likely to occur to the system during transportation) No Iight reflecting device to be indicated by a lively balanced pointer. Constant light emission from the L.E.D.'s. Seven diodes : one central zero and six indicating + 0,5 stop, 1 stop, 1.5 stop - 0,5 stop, 1 stop, 1.5 stop Progressive lighting up of the diodes (one, two, three) ensures a positive indication of difference in exposure.

INSTRUCTIONS FOR USE: 1 Setting up: Connect the battery to the camera. Look in the viewfinder to make sure the camera is in viewing position (mirror in front of aperture). Move the switch (32) to the right. The diodes will light up (camera stopped). Determine with your. light meter, the setting of your diaphragm taking into account the speed of the emulsion and the filming speed. Adjust your lens according to the setting indicated by your light meter (f. 5.6 for example). Looking through the viewfinder, turn with one finger of the right hand the sensitivity potentiometer 34 one way or the other so that only the central diode lights up. This being done, your camera is now set up. 2 Filming Obviously, for keeping a normal exposure, the central diode only must be lighted. If the lighting intensity of the object varies, the control diodes will be seen lit up either + or -, visible in the viewfinder; this will indicate that you overexpose or underexpose. The operator will then adjust his diaphragm by closing or opening it accordingly to come back to the normal exposure which will be shown by the illumination of the central diode only. In effect the operator has a continuous indication of light variations to within plus or minus 1 1/2 stops from the normal exposure and which he can vary at will (eg. for contrast effects).

MIBAC BATTERY

To plug in a Jaeger plug simply turn and push the plug onto the socket until the locking ring clicks into place. To remove the plug, pull on the ridged ring.
At the end of the charge, it passes automatically on the maintenance charge TRICKLE (green diode). The slow charge increases the life of the battery. Operation Plug the cable into the socket (51) - fig DF - at the rear of the charger taking care to position it correctly for the corresponding voltage : 117 volts or 220 volts A.C. 50 cycles or 115 volts AC 60 cycles. Plug the other end into the power supply using a plug corresponding to the mains supply socket. This connecting cable is provided with an earth wire which is yellow/green in compliance with the international standard. Insert the battery into the charger, the red point on top facing the red point which is on the charger. If the battery is correctly pushed in place, its plug (50 - fig AB -) enters the socket of the charger and the control lamp lights up. The charge will not take place if the two red marks do not coincide. - fig EG -. The consumption is 11,3 Amp at 220 volts. When the battery is fully charged the signal lamp will go out. The ensemble -charger/battery- may be left indefinitely connected to the main, without any danger. On the other hand, never leave a battery in the charger if the latter is not connected to the main because the battery will discharge. A safety fuse 52 of 800 milli-amp. protects the charger; it blows in case of excessive voltage increase. Two spare fuses are stored in the two rear feet of the charger -fig FH -

a) discharge the complete battery down to 9 volts. b) discharge each cell using a 1 -Ohm resistance inserted between the terminals, down to 0 volt. c) let the cells stand for one hour. d) recharge the battery for 18 hours. If then the battery has not regained its full performance it is because one of the cells has been damaged and must be changed. A new cell can be inserted into the battery only under the condition that all the cells have a zero voltage.
ACCESSORIES PILOTONE MODULE
As already said, this accessory is a 5 crystal pilot frequency generator 50-60 and 100 hz. Its precision is 510 within a temperature limit of - 20 C to + 60 C (- 4 F to + 140 F). The output tension is 1 v. effective. A three position switch 50-60-100 selects the pilot frequency recorded on the magnetic tape corresponding to the standard used when transfering the sound to 16 or 35 mm perforated film. Our pilotone-module provides two possibilities : 1. If the clapper is required connection by cable (diagram IVIN) of the image units (camera/ battery) to the sound units (recorder/ pilotone module), the MIBAC camera battery supplies the pilotone module. The cable allows the operation of the pilotone module when the camera is running and the recording of the bloop information on the magnetic tape. This associates the crystal generator regularity with the automatic clapper advantages. 2. If no clapper is needed: working without a connection cable between the image units and the sound units (diagram N.O.). In this case, supply of the pilotone module must be ensured by a second MIBAC battery, the first one feeding the camera.
MAINTENANCE RECOMMANDATIONS
If there are deposits in the gate (10) (channel) particulary along the side pressure bars, remove them carefully with a tooth pick or preferably a manicure orange stick. Never use any metal object. It is important that the spring load pressure guide (12) and the pressure plate of the magazine (62) operate smoothly and freely. If they do not work satisfactorily the equipment should be returned to the supplier for adjusting. Avoid the use of brushes since they are generally dirty and have loose hairs. If a hair is caught in the claw slot it may damage the movement; if it is caught in the aperture it will very likely appear on the projection of the film. Using a clean chamois leather occasionally moistened a small amount of alcohol clean the plate, rubbing up and down. Care should be taken not to catch the claw (13) with the chamois.

AFTER SALES SERVICE

As all cinematographic equipment for professional users, a general overhaul carried out from time to time by the maintenance service of your supplier will avoid troubles and waste ot time and money. The spare parts catalogue N * 7011 shows the ACL in the form of exploded diagrams that illustrate the location of all the components that go to make up the camera, motor and magazines.
INSPECTION AND REPAIR TOOL KIT
A full set of tools is available for the work necessary to keep the ACL in tip-top condition. The catalogue NO 7011 and a maintenance booklet are available, on request, to all users who have at their disposal a repair workshop for the cameras.

CLEANING THE MAGAZINE

The sprocket drum and the pressure plate roller-guides may be cleaned with a fluff le cloth slightly moistened with alcohol. For the interior it is preferable to use an air syringe. For the optical parts use an air syringe. Any other cleaning, even with optical or above all tissue paper, could slightly scratch the surfaces.

CHANGING THE MOTOR

If you must replace your motor, please proceed as follows Removal: Disconnect the battery from the camera before this operation is carried out. Take the lens off the camera. Turn the knurled knob 31 to bring the reflex mirror in the aperture centre. In this position the screw 46 of the knurled knob 31 of the motor is adjacent to the guide mark engraved on the motor casing - fig IK -; this position vertically the two driving spigots 42 of the motor - fig JIL - and the two corresponding holes of the camera rubber driver (41) - fig KM -. Undo the three captive screws (40) with a screwdriver or a coin and pull the motor out along its drive axis. NOTE. For checking purpose, the bottom screw (40) is sealed. Take the seal off with a small screwdriver or a small pointed tool to allow access to the screw. Replacement Make sure that the screw 46 of the knurled knob 31 is perfectly in line with the guide Q mar and that the ref lex mirror is in the centre of the aperture. Align the camera plug (44) on the motor with its socket (45) on the camera and push the motor into place along its drive axis - fig JL and KM-. The two drive spigots (42) on the motor must be perfectly in place in the two holes of the camera rubber driver 41. Tighten the three screws 40. Check that the drive is correctly engaged by turning the knurled knob (31) anti-clockwise. It should run ireely. Re-connect the battery.

These above-mentioned precautions concern a short storage period only (approximately one month). Would you kindly consult us for longer periods.

ACL TIME EXPOSURE

Formula: T = Example: CxS O 360 x = 175 49th
T = time exposure C = circonference S = speed of filming (images per second) O = opening of the shutter i.e. frames per second = 1/16th = 1/24 = 1/49 = 1/51 = 1/102 = 1/154
