Title: Multi-Colour Printing Machine
Inventor: FOSTER WILLIAM ROBERT
IPC: B41F15/08
Filed: 1965-10-15
Abstract: 1,156,209. Screen - stencilling machines. POLYPRINT Ltd. 14 Oct., 1966 [15 Oct., 1965], No. 43892/65. Heading B6C. In a step-by-step multi-colour stencilling machine for printing on the surfaces of bottles, preferably plastic bottles, each article is progressively moved from a feeding device 10 to an off-loading position 11 by an intermittently movable conveyer assembly 5. Each bottle, which is manufactured with a peg formed in a recess in its base, is fed into a hydraulicallyoperated chuck-like carrier in such a manner that a locating element on the carrier engages the peg for registration purposes. Each bottle is filled with air introduced via its carrier on arrival at a printing station and is hydraulically raised at each printing station A, B, C or D into contact with a silk-screen which, during the printing operation, reciprocates lengthwise of the conveyer. The squeegee and wiper associated with each screen are automatically operable relative thereto. Prior to moving to the first printing station each bottle is passed whilst rotating about its axis through an automatically operating flame device. The conveyer comprises parallel endless chains which are movable relative to each other laterally in order to accommodate bottles of various heights. The machine is automatically operable by associated electric, pneumatic and hydraulic means. Electric drying means are provided after each printing station and, through microswitches, should a bottle not be present in any one carrier at any one printing station, the hydraulic lifting means are not actuated and the air-filling device remains inactive. Means may also be provided to predetermine the time of the lowering of a bottle from a silk-screen after a printing operation in order that the period during which a bottle is in printing engagement with a screen may be different at different printing stations.

Title: Apparatus to permit testing of a communication circuit
IPC: H04B3/46
Filed: 1975-10-27
Abstract: 1495616 Data transmission; methods of testing MAGNETICS CONTROLS CO 27 Oct 1975 [11 Nov 1974] 44028/75 Headings H4P and H4R A testing apparatus applies a coded series of pulses plus an address through a communication circuit to a remote point where the address is compared to determine identity with a remotely stored address and if correct a loop back circuit is activated in response to an instruction contained in the coded series; an isolating switch for terminal equipment is enabled/disabled in response to an appropriate instruction. At the transmitter Fig. 1 an oscillator 10 output is gated by 12 to give a series of A.C. tone bursts of 2713 Hz determined by a distributer 22 advanced by counter 16. The first burst always represents a 1. As the distributer is advanced, gate 12 opens in dependence of a 1 presented by program switch 18; after 8 steps the 9th bit represents a parity check. The next 2 bits operate a function encoder 20 to provide an instruction to loop back also to enable or disable an isolating switch. At the remote receiver Fig. 2 incoming signals may pass through an inductive pick up 26, loop back switch 28, and isolating switch 32 to terminal equipment 34. Through bandpass filter 36 and threshold limiter 38, incoming signals of minimum duration 30 m.S are converted into square waves. The first pulse received (a pulse = 1, no pulse = 0) latches master circuit 41 which clears 8 bit register 46 and 11 bit counter 44, also starts sync. clock pulse generator 42. The first part of sequence received passes through NAND 48 to 46 so that address may be compared by 50 with address decoder 52 content. The 9th bit (only) blocks counter 44 which enables through gate 54 a parity check circuit 56 and if parity is correct the comparator signals store 60 which primes gates 62, 63 also unlatches 66, 67 so that any instructions, e.g. 10th and 11th bits following the address are accepted in register 46; gates 62, 63 are enabled by 44 so that a positive instruction on lines 68, 69 latch 66 and/or 67 to open switch 32 and/or close switch 28. A nil instruction may be received which operates neither. The 14th count from 44 unlatches 41 hence resetting counter 44 and register 46 into start positions. Additional functions may be remotely controlled through the use of additional instructions together with appropriate gates and latches.

[Also in Division G3] The beam if an electron microscope is kept in alignment by means responsive to signals from detector plates 1 ... 4 radially disposed about the desired path. As shown, voltage builds up on any plate impinged by a misaligned beam until great enough to fire a corresponding neon tube 6 ... 9. Photomultipliers 10 ... 13 operate reversible servomotors 14, 15, according to which is illuminated, to adjust potentiometers 16, 17 in the circuits of deflecting coils 18, 19. A given neon tube flashes, due to voltage build up and discharge, until sufficient correction movement of a potentiometer has taken place. The aperture 5 is slightly larger than the beam. The correction may alternatively be effected by mechanical movement of the electron gun, and alternative methods of detection mentioned are: detecting light from a fluorescent coating on the plates, detecting X-rays produced by suitable plates, detecting, by thermistors, heat produced in the plates, or detecting current in the plates by connecting opposing pairs to differential amplifiers whose outputs energize the servomotors. A system for an electron microscope is described (Fig. 2, not shown) using two stages of detection and correction.

Abstract: 1,101,916. Phase control systems; transistor pulse circuits. MARCONI CO. Ltd. 13 Sept., 1965 [11 Nov. 1964], No. 45970/64. Headings H3A and H3T. A television camera installation comprises a camera unit linked by a cable D to a control unit providing synchronizing pulses and comprising a variable delay circuit B. Synchronizing pulses having a predetermined polarity are fed down cable conductor D to the camera unit, and pulses of the opposite polarity derived from the camera deflection unit are fed back along the cable conductor D to a comparator circuit L where their phase is compared with that of the synchronizing pulses at A. The resulting D.C. error signal is used to vary the delay of unit B. Delay circuit.-Pulses applied to A momentarily switch on transistor B9 to discharge capacitor B2 to earth. Capacitor B2 then charges through transistor B1 until, at a time determined by the value of the error signal applied to the base of B1, the potential across it is sufficient to forward bias diode B6 and switch regeneratively coupled transistors B4, B5 to their conducting state and produce an output at the junction of resistors B7 and B8. After a time, the capacitor B2 discharges to a point where the current through B is insufficient to maintain B4, B5 conducting, and they revert to their non-conducting state.

As shown in Figs. 10, 14, a ratchet wheel 50 carries a sub-shaft 52a passing through a hole 54a in a plate 54. Shaft 52a engages a collar 78, whereby the mechanism is held together. A disc 70 carries a plate 64 and springs 66 with ends 66c which engage internal teeth 72b in gear 72. On the other side of the disc (shown below in Fig. 10) are recesses for a sun pinion 74 mounted on a reduced end 52b of stub-shaft 52a, and a planet pinion 76 which meshes with pinions 74 and with inner teeth 80b of a ring 80 having outer teeth 80a which engage a toothed film winding wheel in the film cassette (not shown). Ring 80 is held in position by a coverplate 82 bolted to disc 60. When the film winding mechanism is not actuated, the ratchet wheel 50 is free to move, and therefore the sun pinion 74 is free and no movement is transmitted to ring 80. When the film wind is actuated, the ratchet wheel 50 is held by a pawl (114b) (Fig. 8) and consequently sun pinion 74 is held fast. The motion of the film winding mechanism is transmitted through gear wheel 30 to gear 72 and via spring ends 66c engaging teeth 72b, to disc 60 so that planet pinion 76 is driven round stationary sun pinion 74, and drives ring 80, which operates the film winding gear in the cassette. After the film has been wound by one frame, or is completely wound, the spring ends 66c slip over teeth 72b in gear 72 until the stroke is completed.
