Title: Apparatus for separating electrostatically charged flexible  recording material from an electroconductive surface
IPC: G03G16/00
Filed: 1973-12-10
Abstract: 1439686 Electro-photography HOECHST AG 10 Dec 1973 [11 Dec 1972] 57091/73 Heading G2H In a deformation phase holographic apparatus, Fig.2, in which a web 4 having a thermoplastic photo-conductive surface is intermittently fed from a supply roll 5 to a take-up roll 6 along a path past an electrically conductive support plate T to which it is attracted into holding contact when charged by a corona 12; to allow the web 4 to be advanced to present a fresh surface to the plate T it is first progressively separated from the plate T by gripping the web 4 with pulleys 9,10 and applying tension to the web 4 by rotatably driving the roll 6 via a slipping coupling while the web passes around a deflector roll 11. As shown, the plate T consists of a flat glass plate bearing a transparent electrically conducting layer 2 of tin oxide with vapour deposited gold electrodes 3 provided at either end. The flat plate T may be replaced by a curved support. The web 4 comprises a dielectric base film with a thermoplastic photoconductive layer on its outer surface. In another embodiment, Fig. 3, the supply roll 5 and a lockable gripping pulley 9 are set in a frame 15  which can be swivelled about a roll 13. Separation of the web 4 is effected by locking the rolls 22, 23 to grip the web 4 while downward movement of the pulley 9, effected by a push rod system 19, 20, causes it first to press the web 4 against a jaw 21 fixed to the frame 15 and then through its action on the jaw 21 causes the frame 15 to swivel downwards about the roll 13 so that the pulley 9 deflects the web 4 downwards, Fig.4 (not shown). In a further embodiment, Fig.7, deflection of the web 4 is effected by a guide roller 31 mounted on a carriage 29 which is pushed towards the plate T and back again. In this embodiment the corona 12, being mounted on the carriage 29, is used to charge the newly exposed surface of the web 4 during the return movement of the carriage 29.

Title: Data transmission systems

Filed: 1973-12-14
Abstract: 1428050 Data transmission; error correction STANDARD TELEPHONES & CABLES Ltd 14 Dec 1973 58019/73 Heading H4P  In a duplex data transmission system in which detection of an error in either direction causes retransmission in both directions, and correct reception (OK) or request for a retransmission (RQ) are included in data blocks so as to be protected by error detection facility, the transmission cycle of each terminal consists of N blocks numbered in a repetitive sequence 1, 2...N+1, which numbers may not be transmitted in normal transmission, but on resumption of error, one or more block numbers may be transmitted temporarily to ensure that blocks are assembled at a receiver in the correct order. The numbers may be held in temporary storage. The arrangement provides indication if a complete cycle of N blocks becomes lost in transit or are faulty.  After synchronization, or resynchronization, an initial service or start of data block is transmitted including a sequence number to set the remote sequence counter to correct reading either initially or after error. Fig. 2 shows a modification and relevant parts of a system such as disclosed in Specification 1,366,908. Formation of blocks is under control of TX distributer 1, and sync. from start control 2 in conjunction with retransmission unit 4 determines whether information is fresh data, retransmission data, sync. or start of data blocks. Sequence counter 3 of capacity N+1, by means of inputs from 1, 2, 4, steps only when blocks are transmitted and is reset to appropriate position for retransmission. Another counter 5 records blocks passed to a utilizing device, e.g. a terminal, and reading is applied to control 2. On resynchronization, control 2 receives a signal from 6 indicating that a start of data block including its sequence number has been received which number is compared with counter 5 thus determining when to enable gates G7, G23. For initial synchronization, sequence counter 2 must be in step with that in the remote transmitter hence by dotted lead Figs. 2-5 counter 2 is set to a number contained in start of data block. In the embodiment described, both directions of transmission are slaved to the same clock. The blocks may consist of data bits, service bits (if any) followed by parity bits hence the service bits may be protected by parity.

Abstract: 1,246,658. Photographic dye-developer diffusion transfer process. EASTMAN KODAK CO. Dec. 12, 1968 [Dec. 12, 1967], No. 59124/68. Heading G2C. A process of producing a colour image by the photographic dye-developer diffusion transfer process in which a photographic material comprising a support and an imagewise exposed lightsensitive silver halide emulsion layer which contains a dye developer or is contiguous to a layer containing a dye-developer comprises allowing an alkaline liquid, that causes the dye-developer to develop the latent image, to permeate said layers and allowing the residual unoxidized portions of the dye-developer to transfer by diffusion in register to an image-receiving material, said process being carried out at a temperature of from 85 to 130 F. and in the presence of a development restrainer which is a bis-benzothiazolium salt wherein two benzothiazolium salt groups are joined, at the respective heterocyclic N atoms thereof, by a long chain alkylene group containing at least 6 carbon atoms in the chain. The salt preferably has the formula: - wherein R is H or an alkyl group having 1-4 carbons; D represents the non-metallic atoms necessary to complete a benzene nucleus which may be substituted; n is a positive integer of 6 to 26; and X<SP>#</SP> is an acid anion. The photographic material preferably comprises at least two light-sensitive silver halide emulsion layers, each of which is sensitized to a different region of the spectrum. The salt is preferably incorporated in at least one hydrophilic colloid layer of the material, prior to processing, at a concentration of from 0.005 to 0À1 g per g. atom of silver in the silver halide emulsion layers. The development restrainers inhibit development of unexposed silver halide which results in more dye developer being available for diffusion into the receiving layer and hence the maximum density of the print as compared with that obtained in the absence of the restrainer, is increased, without increasing the minimum density.

Abstract: 1311550 Luminescent screens THOMSONCSF 23 Dec 1970 [30 Dec 1969] 61301/70 Heading C4S [Also in Division H1] An X-ray or γ-ray scintillator comprises a luminescent layer whose fundamental constituent is alkaline halides on a substrate, the luminescent layer having a fibrous structure constituted by elongated tapered bodies 40 disposed side by side perpendicularly to the substrate with their bases on the substrate. The majority of light is channeled through the bodies. The construction is intended to facilitate thicker screen fabrication to improve efficiency without marring spatial resolution, and assists the adhesion to the substrate allowing flexibility to follow operational screen distortions and tolerating temperature gradients and expansion differences. The halide may be cesium iodide, potassium iodide and sodium iodide with one or more activators such as Tm or Na and in an X- or γ-ray image intensifier tube the composite detector screen (Fig. 1, not shown) may include a photosensitive layer which may include a complex compound of Sb and alkaline metals, Cs, K, Na, Rb, control and focusing electrodes 4, 5, 6 also being included. Photosensitive layer 34 is deposited after assembly. The tubes may also be for storage and recording rather than immediate display. The substrate of screen (2) may be the front face. The fibrous structure is obtained by successive vapourizations under vacuum on to a substrate at low temperature, and adhesion is further improved by the initial deposition with an intermediate porous layer (32) (Fig. 2, not shown), (e.g. Fe, Ni, Co alloy on glass substrate). The halide (24) is vaporized by resistor heater (23) to condense on substrate (31), (30), the successive vaporizations limiting the temperature to which the substrate is raised, 150‹ C. being disclosed as the maximum, maintained by coolant in passages (26). The tapered needles 40 may have 5 to 10 Á base diameter separated by gaps 41 less than 1 Á and may be self-supporting and of density 85 to 95% of the material 24 depending on the evaporation rate.
