Bolex paillard b8l manual

However, if any other apparatuses or lights remain switched on while the projector is in use, the additional current drawn by them will have to be taken into account in calculating the fuse rating. Power taken by M8 projectors VA, or approx. Power taken by other apparatuses in circuit. Total power consumed.

In the example just quoted, a ampere fuse would be required divided by M8R The minimum fuse rating can be calculated in the same way as in the case of the M8 projector. The only alterations that must be taken into account are those that affect the mains supply voltage and the projector's power consumption. Total power consumed VA, or about watts. The minimum fuse rating should be at least 5 amperes divided by In this case, a standard 6-ampere fuse would prove sufficient.

Setting up the projector The operati ng switch 20 shou Id be on "Stop. To do the latter, turn the projection lamp in the direction shown by the arrow. The flanges on the lamp base 22 should touch the stops in the lamp-holder socket. The projector can either be stood on a table or on its carrying case, or it can be set up on the special Paillard Bolex tripod stand for cine projectors.

An image of the aperture in the gate will appear on the screen. Bring this image into focus by turning the focussing' ring 8 on the lens. Use the speed con- trol knob 23 to adjust the motor speed so as to eliminate any trace of flicker on the screen. Center up the image of the gate aperture in the middle of the screen, by turning knobs 10 and Reset the operating switch to "Stop.

Place the projector on plat- form of tripod, taking care that its feet slide into the appropriate depressions. Fasten the projector into position by screwing the knobs down hard.

Figure 7 shows the projector pointed downwards. Figure B shows the projector pointed upwards. To render the projection beam horizontal, turn screw d on the tripod. Set the operating switch to position c, focus the image of the gate aperture on the screen by turning the focussing ring on the lens, adjust the motor speed to eliminate flicker on the screen, and center up the image on the screen by means of the tripod screw.

Return operating switch 20 to "Stop. There is no need to make any provision for lighting the mechanism or controls while a film is being shown, as the film transport mechanism is very simply designed, and the operating controls and stopping device are within easy reach.

The universal mains outlet 17 fitted to the projector is intended to supply an auxiliary room light such as a table light or standard lamp of the same voltage as the mains supply to which the projector is connected.

However the power in watts consumed by the lamp should not be greater than the mains supply voltage. Model M8R V watts maximum, and so on. The auxiliary lamp is extinguished automatically when the projection lamp is switched on. If the operator wishes to be able to dim the room lighting gradually at the beginning of a show, he should insert a variable resistance or "dimmer" of the appropriate rating in the auxiliary lighting circuit.

Correct operating procedure in this case is first to dim the room lighting by moving the slider on the dimmer resistance, then to set the projector running and show the fil m. At the end of the reel the same operations shou Id be repeated in the reverse order. Loadin o Raise up the upper spool arm 11 intothe erect position by carrying out move- ments e and f simultaneously. Place the full spool on the upper spool spindle. The film unwinds in the direc- tion shown by the arrow, with the perforations on the same side as the slotted spindle tip that keeps the spool in place.

Open the film gate by swinging the lens-holder forwards on its hinges. Place the empty spool on the back take-up spindle 18 and unwind about 30" of film. Insert the film between the upper sprocket guides 2 by pulling it slightly in an upwardly direction. If the sprocket teeth do not enter the film perforations immediately, pull the film forwards a little.

A slight click tells when the film is in place. Place the left index finger just under the automatic loop-former 5 and form the lower loop, then guide the film over the lower sprocket guides 7 with the right hand, and pull on it slightly in the direction shown by the arrow. The upper and lower loops should be roughly the same size. Pass the film under guide-rollers 9 and 3 and fasten the free end to the core of the empty take-up spool.

Turn the latter 'in a clockwise direction so as to tighten up the film slightly. Projecting Both models M8 and M8R are fitted with a special safety device centrifugal con- tactor which prevents the projection rate from falling below the minimum necessary to ensure adequate ventilation.

When the projection rate falls below 12 frames per second, the motor speed starts to oscillate up and down, and the centrifugal contactor becomes noisy. If this occurs, increase the projection rate by turning knob Set the motol" and film transport mechanism running by placing the operating switch 20 on position b see general view. Now turn the switch to position c. This switches on the projection lamp and turns off the auxiliary room lighting.

Using the speed control knob 23, adjust the projection rate so as to eliminate any trace of flicker on the screen. Bring the picture into focus by turning the focussing ring on the projection lens 8. Check that the picture is properly centered on the screen, and adjust framing if necessary by turning, knob End of the reel To switch off the projection lamp and turn on the room lighting, while keeping the motor running at the same time, simply move the operating switch from c to b.

To stop the projector completely motor and lamp , simply press on the operating switch as you would on a bell push. The auxiliary room lighting will light up automatically. Instantaneous stopping device To bring the projector to an immediate stop, press on the operating switch as described in the preceding paragraph.

Rewinding-whether by hand or using the motor-must always be carried out with the lens-holder in the "closed" position. Manual rewind 1. Screw the rewinding handle into the upper spool arm. Take hold of the free end of the film, and fasten it to the core of the upper spool now empty , following the path shown.

Rewind the film by turning the handle in the direction shown by the arrow. Motor rewind 1. Fix the spring belt into place as shown Fig. Take hold of the free end of the film and fasten it to the core of the upper spool, follow- ing the path shown.

Set knob 23 nearly to minimum speed. Set the operating switch on posi- tion b. Engage the rewinding mechanism, by pressing on the grooved rewind- ing knob When all the film has been wound back, stop the projector by pushing on the operating switch.

IV V Unloading To unload the projector after showing part of a film, proceed as follows Open the gate by pulling the lens-holder for- wards.

Free the film from the sprockets by pressing on part g of the sprocket guides. Rewind the film by hand or using the motor, as described above see Fig. Changing the projection lamp Open the combined panel and lamp mount 21, press down on the lamp and turn it a quarter-turn in the direction shown by the arrow.

Remove the lamp, and put in a new one by carrying out the same operations in the reverse order when inserting the new lamp, see that the flanges on its base are opposite the corresponding gaps in the lamp-holder socket. The standardized projection lamps now on the market are practically inter- changeable, so that no readjustments will be necessary when the lamp is changed.

To ensure a maximum life of the lamp, the lamp-holder socket is fixed on shock-absorbing elastic stands. Lubrication After every 25 hours of use the pro- jector should be lubricated by intro- ducing 3 or 4 drops of high-grade sewing-machine oil into the lubricating ducts, which are marked in red, at the same time letting the motor run very slowly.

Duct i lubricates the central part of the mechanism, and ducts hand k lubricate the upper spool spindle and the motor.

Cleaning Optical equipment: Using a dry, clean paintbrush with fine soft hairs, remove all dust from the lens, the reflecting mirror next to the projection lamp, and the glass screen 24 of the catathermic filter. Then clean all the glass su rfaces with a clean, dry chamois-leather cloth.

Pressure-pad on lens-holder and gate These two parts, which are very easy to get at, should be cleaned fairly often to remove any deposits of 10 A soft, dry rag can be used for this purpose. Check that the gate aperture is free from any particles of foreign matter by inspecting its image on the screen.

Sprockets and rollers: Any deposit of dust or emulsion that collects on the sprockets, film guides or rollers may cause scoring of the film. Although the M8's sprockets and guide rollers have been designed expressly to prevent the possibility of such damage occurring, by avoiding all contact with the exposed portion of the fi 1m, these components should never- theless be cleaned regularly.

Deposits of emulsion are more likely to occur when freshly-developed films are being shown. VI VII 11 The M8 projector and its accessories Kayla Rogers Dec.

It was superseded by the B8LA in Metal parts are chrome-plated. When a roll runs through the camera, only half the width of film is exposed.

The spool is then reversed and run through again, exposing the other half. When processed, film is split and spliced together giving 50' for projection. Projection time at 16 fps for 25' roll is 4 minutes. THREADING: manual, with no loop forming; with the pressure pad opened the film is simply placed over a guide roller, threaded behind the gate, over the bottom guide roller and onto the takeup spool. Generous winding key, attached to the camera, folds back against its side when not in use.

Spring cannot be over-wound. Accessory prism attachments allow for filming with 5. The lever can be locked to prevent accidental exposures, or set for continuous hands-free filming.
