Patent GB-409764-A (GB)
Title: Improvements in and relating to mechanically operated presses
IPC: B30B15/00
Filed: 1932-11-10
Abstract: 409,764. Gearing for stopping and starting machinery. STRONG, A. G. O., 26, Henleaze Gardens, Westbury-on-Trym, Bristol. Nov. 10, 1932, No. 31729. [Class 80 (ii).] The driving-mechanism of presses is stopped and re-started automatically to allow a dwell at the point of maximum pressure. The rotation of a shaft 1 in an anti-clockwise direction engages a clutch against the action of a spring and sets the driving-gear in motion. This rotation is effected initially by the depression of a pedal connected by a link 34 to an arm 5 fixed on the shaft. The rotation of the shaft also causes a catch lever 6, fixed thereon, to rotate until a nose-piece thereon engages the end of a two-armed lever 8 and prevents the reverse rotation of the shaft under the pressure of the clutch spring. The catch-lever 6 also engages with a peg 32 on a loosely-mounted spring-controlled guard plate 3 and carries the latter round with it, in order to free a pawl 19 and detent 12 from a ratchet-wheel loosely mounted on the shaft 1 for a purpose hereinafter described. The guard 3 is retained by a second nose-piece which engages the end of a lever 9 while the ratchet wheel is prevented from rotating by a spring cord wound round the hub and anchored to the framework, which maintains the stop 22 in contact with the disengaged detent 12. The parts continue in this position until the point of maximum pressure, when a stop 25 on a moving part of the machine trips the lever 9 which carries lever 8 with it and thus releases the shaft and guard plate, both of which are then restored by their springs. This puts the clutch out of action, and also reengages the pawl 19 and detent 12. At the end of the dwell period, the bell-crank pawl-carrying lever 4, which is operated periodically by a cam 15 on a constantly-rotating shaft against the action of a spring 18, is made effective by the engagement of the pawl and rotates the ratchetwheel, which is then held by the detent. A lug on the ratchet wheel engages the catch lever 6 and so rotates the shaft 1 to re-engage the clutch. This rotation of the shaft again rotates the guard plate to release the pawl and detent as previously described, on which the spring cord restores the ratchet wheel to its original position. The setting of the adjustable stop 22 on the ratchet wheel varies the period of the dwell obtained. To stop the press automatically at any desired point so that it can only be re-started by hand, a stop 27 is arranged on a moving part of the press to contact with a lug 28 on the lever 4 and remove the latter clear of the cam 15. To stop the press manually at any point, a lever 29 is depressed against the action of the spring 31. This trips lever 8 without releasing lever 9, thus allowing the shaft 1 to rotate to release the clutch, but maintaining the pawls free of the ratchet wheel so that the latter cannot be actuated to re-start the machine.

Title: Cinematographic projector

Filed: 1972-07-06
Abstract: 1395622 Cinematography EASTMAN KODAK CO 6 July 1972 [6 July 1971] 31780/72 Heading G2E In a cine projector having a film 11 moved continuously through a film gate 12 includes an oscillating mirror 44 acting as an optical compensator to provide a stationary image on screen 51. The movement of the mirror 44 is derived from a continuously rotating drive-shaft 18 powering film drive roller 15 via an electromagnetic clutch 54 and gear-box 71. The mirror 44 is moved from a first to a second position, when the shutter 40 is open, by activation of the coils of the clutch 54. When the shutter is closed, the clutch is deactivated to sever the connection with driveshaft 18 and the mirror 44 is returned by spring 59; the spring 59 is wound up by the rotation of shaft 57 to move the mirror 44 from its first to second position. The control and synchronization of the movement of the shutter 40 and mirror 44 is controlled by the sensing of some regular discontinuously occurring feature on the film, e.g. the edge of a film frame or as shown film perforations 22, by a photo-cell 112. As shown in Fig. 4 the photocell output is applied to the circuit 117 so that difference amplifier and clipper 210 provides a gating pulse to AND gate 211 which is so delayed by the time constants of integrators 206, 208 that only a pulse, passing through amplifier 204, which corresponds to the trailing edge of a film perforation 22 is passed to OR gate 224. This avoids inaccurate control due to worn leading ends of the film perforations. The circuit 104 on receiving a pulse to OR gate 224 switching the flip-flop 212 to its "one" condition provides signals to the shutter 111 and clutch 106. The flip-flop is reset via OR gate 226 and delay circuit 216. Should no pulse from circuit 117 be received, the resetting of flipflop 212 causes delay circuit 222 to provide an input to the OR gate so letting the projector function in the absence of control pulses from the film. When pulses are again received the control system is re-synchronized with the film by an input to the delay circuit 216 which by-passes the flip-flop. This ensures that the next control cycle will be completely sychronized.
