Title: Improvements in apparatus for television and for recording and reproducing pictures and the like
IPC: H04N3/00
Filed: 1928-10-25
Abstract: 328,286. Walton, G. W. Oct. 25, 1928. Television.-The elements of a picture &c. are located simultaneously on a strip having definition in one dimension only, by means of an optical or other device at the transmitter, while a similar device at the receiver reconverts the received one-dimensional image to a normal picture. In the embodiments illustrated, the optical device takes the form of a reflecting or refracting echelon device, such as e, Fig. 12, the steps of which may be linearly or angularly displaced in any order, and may be lenticularly formed. The optical system described deals with an object or scene a viewed by a lens b which would form a real image at the entrance of the device e. A cylindrical lens c, however, forms a horizontal focal plane only at e, and a smaller vertical focal plane at d. A field lens g placed before e ensures the entrance of light pencils to the different laminations of e at approximately equal angles. The lenticular formation of the laminations ensures a one-dimensional image being formed at f, the imperfect image at d being viewed individually by each lamination. Internal reflection in the laminations prevents vertical divergence of the rays, and may be further ensured by silvering the surfaces. The definition of the picture is determined by the number of laminations in the echelon; and a simple scanning device, such as an apertured disc or drum, a revolving or oscillating mirror, or the oscillation of one of the members of the existing optical system, may be used. Synchronization of transmitter and receiver is unnecessary, as a difference of speed results only in a lengthening or shortening of the received one-dimensional image, which can be corrected optically. For the transmission of pictures, the picture may be recorded on a film as a one-dimensional picture, scanned, received on a similar film, and reconverted to a twodimensional picture.

Abstract: 845,320. Roller conveyers. BEACON PRODUCTION EQUIPMENT CORPORATION. Oct. 2, 1957 [Dec. 31. 1956], No. 30911/57. Class 78 (1). [Also in Group XVII] A machine for stacking articles on pallets (see Group XVII) comprises means for forming a tier of articles on movable plates above the pallet and for depositing the tiers on the pallet, the latter being supported on an elevator which lowers it step-by-step to receive the tiers. The machine incorporates means for turning selected articles to produce a desired pattern in a tier and pallet storing and ejecting devices. The articles, cartons, for example, are fed by a roller conveyer D on to a similar conveyer C which carries them against a stop so that they line up in front of a ram plate 10. The conveyer C includes spring-loaded rollers r, Fig. 9, which are depressed by the weight of the articles to actuate switches in series. When these are all closed, the ram pushes the row of articles on to assembly plates 23, 23<1>. A ram-controlled stop 93, Fig. 9, rises to check advance, of other articles until the ram returns. Articles transferring normally from conveyers D to C are turned through 90 degrees by the motion of the conveyers, a roller 423 being provided to assist this. However, articles may be transferred without turning by conveyer chains 429, Figs. 1, 4, mounted to be raised by solenoid and toggle means 435-437, 440 to project above the rollers of the conveyer C. An article passes from the conveyer D on to these chains which feed it against a switch lever 441, actuation of the lever causing the chains to be lowered to transfer the article to the conveyer C. The pattern may be pre-arranged by means of a step switch operated by photo-electric means 402 responsive to movement of articles along the conveyer D to the switch controlling the solenoid 440.

Abstract: 895,982. Moulding microcellular rubber. C.I.C. ENGINEERING Ltd. Oct. 30, 1958 [July 30, 1957], No. 30949/60. Divided out of 895,981. Class 87(2). During the moulding and simultaneous vulcanization of a microcellular elastomeric material expansion of the material is unidirectional and is controlled by valve means in a pressure fluid system for applying pressure to relatively movable components forming a mould cavity. In a machine for moulding and simultaneously vulcanizing a rubber sole and heel unit to a shoe upper, and including a last 20, Fig. 3, adapted to be embraced by side moulds 1 movable by fluid pressure cylinder units 3, moulding pressure is applied to the sole and heel unit by a ram 2 operated by a cylinder unit 7 having associated therewith a secondary piston 23. When the ram 2 is moved upwardly by fluid pressure applied to the unit 17 for applying the moulding pressure fluid passes from above to below the piston 23 through a non-return valve 29. After the full moulding pressure has been applied for a predetermined period, e.g. 1 minute, electrically controlled valves are actuated to reverse the fluid supply to the unit 7. The ram 2 is then retracted slowly to allow expansion of the moulding material, the rate of retraction being controlled by the restricted flow of fluid from below to above the piston 23 through a constricted throat 31. At the end of the vulcanization period the piston 23 uncovers an inlet to a by-pass 33 so that the ram 2 and piston assembly descend rapidly. A further embodiment is described in which the rapid descent is effected by the opening of a valve in the piston 23.
