Patent GB-926643-A (GB)
Title: Roll-film camera
IPC: G03B1/66
Filed: 1962-03-05
Abstract: 926,643. Roll-film cameras. AGFA A.G. March 5, 1962 [March 7, 1961], No. 8486/62. Class 98 (1). A roll-film camera has film frame measuring and counting mechanism couplable to the spindle of the supply spool, by axial displacement of either said spindle or of a coaxial spindle of the said mechanism. In the form shown, the film is inserted into the camera on a spool 9, which, on closing the camera body, is held at one end by a spring-tensioned spigot 13, and at the other by a fluted rubber cone 12. This cone forms one end of a spindle 8 slidable in a bush 7 integral with the camera housing 1; the other end of the spindle bears, via a spring 10 and ball 11, against another fixed part 5 of the housing. On the bush 7 is mounted a rotatable sleeve 22, carrying a flanged filmcounting disc 23, and another disc 24. Sleeve 22 (and hence discs 23, 24 also) can be rotated by spindle 8 through gear-wheels 15, 17 and 20, 21. Disc 24 has notches 25 corresponding to the film frame numbers, and is coupled by a spring 27 to a further disc 26 having teeth 28 corresponding to the notches 25. The film is wound from supply spool 9 on to a take-up spool engaged by spindle 29, by means of a rapid-wind lever 30, which at the same time sets the shutter. A pawl 35 has a tooth 38 at one end which engages a ratchet 31 on lever 30, so preventing it from turning, in the position of Fig. 4, and a tooth 39 at the other end which locks into one of the notches 25 in disc 24. On depressing the camera release 41, pawl 35 is pushed anticlockwise about its pivot 34, which disengages the teeth at both ends. Disc 26 can now rotate a short distance anticlockwise relative to disc 24 under the action of spring 27, so that teeth 28 are now above the notches 25, preventing the return of tooth 39. At the same time, a turned-over lug 40 at the end of a second pawl 37, spring-connected to the first pawl 35, engages under the camera release 41 so that it cannot be operated again. The rapid-wind lever is now operated, winding on the film, and rotating, via spindle 8 and the gear-wheel train, the counting disc 23 and the disc 24. Disc 24 also rotates slightly with respect to disc 26, so that tooth 39 can fall once more into the next notch 25. The pawls take up once more the position of Fig. 4, so that after the film has been advanced one frame, lever 31 cannot be operated again, until the next operation of release 41. Figs. 2 and 3 (not shown) illustrate different methods of coupling the spindle of the supply spool to the spindle of the counting mechanism. The Specification refers to advantages deriving from coupling the counting mechanism to the supply spool instead of to the take-up spool.

Title: Improvements in delay devices
IPC: H01J25/34
Filed: 1949-03-29
Abstract: 663,054. Signal detaying equipment. RADIO CORPORATION OF AMERICA. March 29, 1949 [March 31, 1948], No. 8496/49. Class 40 (iv). Apparatus for delaying a signal by a predetermined amount comprises two delay devices to which the input signal is applied in turn for periods equal to the required delay and whose outputs are combined to produce the required delayed signal. As shown, the pulse generator 2 feeds a sweep circuit 4 for the two storage tubes 8, 10. The generator 2 also feeds a 2: 1 frequency divider 12 which synchronizes a multivibrator 14 producing alternate positive and negative square waves which when applied to the electronic switch 16, permit or prevent passage of signals from the source 18 for recording on the storage target 24 according as the period is odd- or even-numbered. The output from multi-vibrator 14 also feeds a polarity reversing circuit 32 whose output controls the electronic switch 30 so that it only feeds signals from the output of the delay device 8 to the mixer 34 during the even-numbered periods when the signal is read off and obliterated from the target 24. In a similar manner during the even-numbered periods the input signals are fed to the tube 10 by the switch 36 controlled from the polarity reversing circuit 32 and the output signals fed to the mixer 34 during the odd-numbered periods by the switch 50 under control of the multivibrator 14. The mixer recombines the output signals to reproduce the original wave-form delayed by an amount equal to the period of the generator 2.

March 18, 1921, Track apparatus for stopping trains.-Apparatus on the track is actuated from the signal to engage apparatus on the locomotive so that when a train runs past a signal set against it, the steam is cut off and the brakes applied. The rack a is spring mounted on arms b on spindles f in a frame c adjacent to the track, and an arm e on one of the spindles is connected by the rod d to the rod g by which the signal is operated. In its raised position the rack a engages the pinion l at the bottom of the vertical shaft k on the locomotive. Motion is communicated from this shaft by bevel-gearing m, n and worm gearing p, q to a rack r, which has a dependent lug s to shut off steam by operating the arm t, and which is connected by a rod u to the handle w to apply the brakes. The apparatus on the locomotive can be returned to its running position by the handle x and gear y, z, which is normally held out of action by the locking-lever B. If the signal is operated to indicate a clear line, the rack occupies the position shown in dotted lines in Fig. 2 and does not engage the pinion l. The Provisional Specification states that the pinion l and rack a may be rubber-covered.
