Abstract: 1523741 Exposure control in photographic copiers HOECHST AG 14 Aug 1975 [16 Aug 1974] 33890/75 Heading G2A The image of a microfilm 4 is projected on to sensitive material 11 and during an initial period of the exposure a photo-cell 14 is moved across the sensitive material 11 to detect the optical densities of different areas of the projected image, a discriminator 17 selects the maximum or minimum density and exposure time is controlled accordingly. As shown, light is directed on to the photo-cell 14 by a mirror 15, both the photo-cell and the mirror being mounted on a wheeled carriage 13 movable over the sensitive material 11. In Fig. 3, the discriminator selects the maximum photo-cell signal i.e. the minimum density, and after a time sufficient for density measurement to be completed, a generator 18 generates a sawtooth voltage whose gradient is determined by the selected signal. A comparator 19 compares the sawtooth with a reference voltage to switch off the exposure lamp 1 or to close a shutter 2. In Fig. 4 (not shown), the photo-cell signals are passed through a quotient former (20) which forms their reciprocals and a discriminator (17) selects the highest reciprocal (which corresponds to the maximum optical density). After a time sufficient for density measurement to be completed, this signal is fed to a comparator (19a) which compares it with a sawtooth voltage of predetermined gradient.

Abstract: 935,505. Coin - freed kinematographs. MOVIESBOX GENERAL SYSTEM S.r.1. Got. 11, 1960 [Oct. 15, 1959; Feb. 1, 1960], No. 34755/60. Class 27. [Also in Group XX] In a cabinet-type coin-operated apparatus for selectively projecting one of a plurality of films, the films are housed as endless loops in individual " projection units," each comprising an arm 5 incorporating film transport mechanism and a film magazine 6, arranged as a circular array on a magazine-wheel 4. Introduction of a coin or the like electromagnetically couples shafts 16 and 16<SP>1</SP> and the wheel 4 may then be manually rotated by means of the index wheel 13 to bring a selected film into alignment with a fixed optical system 30 for back-projection, via mirrors 31 and 3, on to screen 2. Each arm 5 (see Fig. 2) has a toothed sector 9 and, when a selected projection unit arrives at the projection position, engages a pinion 8 which, in response to a manually-operated push-button signal, will then be driven to pivot arm 5 on pin 7 and thus bring a gear 24 of the projection unit into engagement with a fixed film-driving gear 22. After a suitable delay the latter is driven, via worm 21, by motor 20 and the film feed proceeds continuously, via gears 24, 25 and sprocket 23, 23<SP>1</SP>, an octagonal prism 26, rotating with gear 22, providing optical compensation. Light from a fixed source reaches the film via a mirror that enters the projection unit in the projection position. A magnetic sound head 45 is then also in engagement with the film. At the end of a complete run of the film loop, a switch is energized to stop further film feed and reverse the motor driving pinion 8 so as to restore the projection unit to an idle position. In another embodiment, each projection unit is provided with intermittent claw-feed mechanism comprising (see Figs. 5 and 6) a claw 73, eccentric driving cam 72, and an obliquelydisposed rotating plate 67, which as it rotates moves the claw perpendicularly to the film for intermittent engagement and disengagement of the film perforations in synchronism with the film-transporting movement provided by the cam 72.
