Title: Improvements in and relating to communication systems
IPC: H04L27/20
Filed: 1968-06-06
Abstract: 1,220,879. Digital transmission systems. MILGO ELECTRONIC CORP. 6 June, 1968 [1 March, 1968], No. 26884/68. Heading H4P. In a differential phase modulated data transmission system the receiver develops a pulse which samples each modulation period, the resulting signal gating a continuously cycling counter to a comparator which compares the counts during adjacent samples to determine the original data. Transmitter, Fig. 3.-Serial binary data, e.g. from a computer, passes to shift register 215, 220, 225 whose outputs pass to a code converter consisting of gates as shown. As each new input bit arrives at 211 a 3-bit signal passes on lines 265-267 to comparator 270, whose other inputs come from stores 305-307. To ensure that a phase change is caused by successive 3-bit groups of input bits a bit-rate clock signal on line 210 is divided by 3 at 230 and passes via unit 245 to a gating logic 290. The logic is also fed with the comparator output and its output controls the phase of the output of a divider 295 by inhibiting switching in its various bi-stable components. An output signal is taken from the final stage of the divider and represents the input data as a phase-shifted differential square wave. The stages of the divider also feed the store 305 so that the comparator 270, by reference to its inputs which represent the existing phase of the transmitted signal and a required phase shift representative of the input data, can determine the amount by which the divider phase is to be shifted. The phase-shifted data signal at 255 passes via a filter to a unit which lowers the carrier frequency to a value f 0 . This signal passes to a narrow band filter having a centre frequency # 0 , this filter being connected to a telephone line. Receiver, Fig. 5.-The received signals pass via a filter and a fixed equalizer to a unit which raises the carrier frequency, the square wave output signals passing to gate 121 and to a unit 120 which derives from the received signals various clock signals. One of these samples the received signal at gate 121 and consists of a pulse occurring at the centre of each modulation period. A high-frequency clock pulse source 425 feeds both gate 121 and counter 450 which cycles once in the duration of the sample pulse. When gate 121 outputs a pulse the current count from counter 450 is stored in register A and represents the current phase of the received signal. The content of registers A and B are subtracted, register B containing a count representing the phase during the previous modulation period. The resultant signal represents the differential phase and passes to decoder 480 where it is translated to the corresponding 3-bit binary data signal. This signal is serialized at 500.

Abstract: 1316892 Image pick-up tubes FERNSEH GmbH 19 April 1971 [20 April 1970] 26902/71 Heading HID A method of operating a TV camera tube wherein the tube is disposed within a focusing system comprises passing current through a main focusing coil (4), Fig. 1 (not shown), producing a constant value H 0  focusing field along a major portion of the tube to a point adjacent the target and passing current through means such as coil 5 producing a local increase in the focusing field, relative to the constant value, from the said point along a further portion of the tube, the focusing field then decreasing to a value at the target less than the constant value, the mean value of the field from the above point to the target being equal to the constant value. The focusing coils and deflecting coils (6) may be screened by an external Mu metal winding or ferrite sleeve. The above field compensates "beamlanding errors" due to non-perpendicular landing of the electrons on the target, non-perpendicular landing also reducing absorption efficiency, and eliminates rotation errors apparent in the picture corners. The inward radial field imparting rotation in opposite sense to that caused by weakening of the main focusing field may be generated at 2 cms. from the target for example and produced by an auxiliary coil (5) or by increasing the ampere turns of the focusing coil. Described is semiconducting lead oxide target (2) with transparent tin oxide coating. Coils (4) and (5) are preferably in the

Abstract: 1454450 Film processing AMERICAN VIDEONETICS CORP 18 June 1974 [27 June 1973] 26981/74 Heading G2X In a method of applying activator fluid to the surface of an image receiving film 27 for use in a transfer process an absorbent resilient pad 91 is compressed against the film, the pad is filled with activator fluid, the fluid is then drawn out of the pad and the pad is dried out by applying a vacuum to the pad; finally the pad is retracted from the film to sponge off any excess activator. The device for carrying out such method is used in an apparatus for transferring images recorded sequentially on microfilm to selected positions on a receiving film. The microfilm 22 is imaged by lens 19 and then transported to transfer station 71. The area of the receiving film on to which the microfilm image is to be transferred is positioned at an activator station 28. A solenoid 96 is energized to raise a shaft 86 and press a cup 88 containing a compressible pad 91 into engagement with the surface of film 27. The edges of the cup 88 form a seal with the film so that when a vacuum is applied to conduit 92 and valve 101 is opened activator fluid is drawn into the pad and applied to the film. Subsequently valve 101 is closed and valve 103 opened to an air supply so that the pad is dried. Finally shaft 86 is lowered to move the pad out of engagement with the film and sponge off any remaining fluid. The surface of the film which now carries activator is now moved to the transfer station and pressed into engagement with the latent image area of the microfilm. Developer in the latter is activated, a negative image is developed and a positive image is transferred to and developed in the receiving film. This is now moved back to the processing station where in a sequence similar to that for applying activator the film is washed (valve 102) and dried. Other details are similar to those described in Specification.
