Title: Animated picture displays and methods and apparatus for producing them
IPC: G02B27/06
Filed: 1949-10-13
Abstract: 669,045. Zoetropes; photographic printing apparatus. ODLE, J: E. Oct. 13, 1949, No. 26654/48. Classes 97 (i) and 98 (i). An animated picture display device consists of a plurality of photographic image-bearing elements in kinematic sequence assembled in pack form, each element being elongated to provide an extension piece for binding the pack, the elements carrying register marks in uniform relation to the images, whereby, in assembling the pack, the several images may be brought into correct superimposed position. If the film runs vertically through the kinematograph camera the negatives may be printed at one side of a paper strip, for example in a continuous-feed slit-type printer, the register marks being printed photographically or punched mechanically. The strip is then severed transversely, the unexposed areas being used for binding. If the film runs horizontally through the camera the negatives are printed to occupy substantially the full width of the paper strip with a longitudinal separation greater than on the film. In an apparatus for this purpose, as shown, the negative film is fed between spools 15, 16 through a gate 17 and an image is projected'by an optical system 28, 29, 30 on to the paper strip 31. A shaft 20 is driven continuously by a motor 27 and the film is fed intermittently by the maltese cross mechanism 18. While the film is stationary the cam 42 closes the switch 44 to light the printing lamp while the paper is held against the mask 50 by a platen 35 urged by a spring 36. The paper, being fed from a spool 32 by a continuously-driven roller 33, forms a loop at B. While the film moves between exposures a cam 47 operates the switch 48 to energize the solenoid 37 to retract the platen 35. The paper is then fed by a . spring-loaded or weighted roller 38 taking up the loop B and forming another behind the continuously-driven roller 39. In a modification, film and paper are fed in unison by separate maltese cross mechanisms. The mask 50 has a slit through which a reference mask is exposed near each picture. Alternatively, the platen 35 may carry a projection which punches a hole in the paper each time the platen clamps it for exposure.

IPC: H01J17/48
Filed: 1952-10-28
Abstract: 722,240. Multi-stable state circuits. STAN. DARD TELEPHONES & CABLES, Ltd. Oct. 28, 1952, No. 27056/52. Class 40 (6). A multi-stable state circuit comprises a coldcathode gas-discharge tube having a common anode and two sets of cathodes so that a discharge in an intermediate cathode of either set primes only one adjacent gap of the other set and the application of a pulse causes the discharge in the cathode of one set to be transferred via a gap of the other set to the next cathode of the first set which alone remains discharging at the end of the pulse. The Figure shows a multi-stable state circuit comprising a cold-cathode gas-discharge tube of the type described in Specification 692,415, [Group XL (a)], which has a common anode and one set each of storage and transfer cathodes. The transfer cathodes are commoned internally and brought out to a single lead to which positive pulses are applied at T. The cathodes are directional so that when a given anode/storage cathode gap is discharging the anode/transfer cathode gap in front of it is primed to a greater extent than that on the other. A positive pulse applied at T causes the transfer cathode/anode gap to be extinguished and that storage cathode/anode gap which is primed in the direction of preferential travel is fired. When the pulse ends the following transfer gap is fired and the preceding storage one extinguished, thus each positive input pulse steps the discharge from one transfer gap to the next.
