Abstract: 1,252,695. Electrolytic coulometers. L CORRSIN, Dec. 15, 1969, No. 60926/69. Heading G1Q. An electrolytic coulometer of the type incorporating mercury electrode bodies separated by an electrolyte, and in which in operation mercury is electrolytically transferred between the electrodes, includes a passageway by-passing the electrolyte between the electrodes substantially filled with liquid and a pump for impelling the liquid through the passageway, there being no inter-connection through the passageway between the mercury bodies. The arrangement has application in mechanically resetting moving drop or fixed cell type coulometers and in providing a coulometer driven clock. In a moving drop type coulometer, Fig. 1 wherein passage of electricity is indicated by the movement of the electrolyte drop 18 (potassium iodide and mercuric iodide solution) as mercury is transferred between columns 14 and 16 due to the passage of current between electrode connection 30, 32, a flexible tube 12 mainly filled with mercury provides the by-pass and is acted on by a peristaltic pump 20 which compresses the tube, separating the two mercury columns. Movement of the pump along its support plate 24 will reset the coulometer when required. In other similar arrangements, a rotary pump Fig. 2 (not shown), piston pump Fig. 4 (not shown) or gear pump Fig. 7 (not shown) may be used. An insulating liquid may separate the mercury columns in the flexible tube Fig. 5 (not shown). In a coulometer driven clock arrangement Fig. 3, a rotary pump 40 is operated continuously to hold the electrolyte drop stationary by a servosystem. The position of the drop is sensed photoelectrically at 58 and any movement generates an error signal at an amplifier 26 which causes a servomotor 50 to operate the pump to restore the position of the drop, The servomotor also drives a clock 54. In a fixed cell type coulometer Fig. 6 wherein mercury is transferred between columns 14<SP>1</SP>, 16<SP>1</SP> separated by an insulating liquid 74 through a fixed electrolyte 78, a by-pass column 76 is provided, around which mercury may be pumped (at 20) from one column to the other to reset the device.

Abstract: 1315663 Selective signalling NATIONAL RESEARCH DEVELOPMENT CORP 22 July 1970 [23 July 1969] 37138/69 Heading G4H [Also in Division H4] In response to a gamma ray being incident on one of the gamma ray counters of a gamma camera, output pulses corresponding to the co-ordinate position of the counter are fed via respective preamplifiers 3, 4 and pulse amplitude discriminators 5, 6 to binary encoders 7 and 8. The gamma camera may comprise a rectangular slab of semi-conductor material subdivided by orthogonal ribs 1 and 2, each intersection of these ribs forming a discrete gamma ray counter-see Specification 1,269,634. Each horizontal and vertical rib is connected to separate amplifiers 3 and 4 and discriminators 5 and 6, and as shown the eight discriminators are coupled to encoder 7 and the eight discriminators 6 to encoder 8 and the resulting binary numbers characterize the particular intersection. Outputs of the encoders are fed to digital-toanalogue converters 9 and 10 which generate pulses of amplitude proportional to the input binary number. These are amplified 11 and 12 and applied to the X and Y deflection plates of CRT14, a brightening pulse generated by encoder 7 being simultaneously applied thereto. In accordance with the invention noise signals from generator 16 are also applied to the amplifiers 11 and 12 so that instead of displaying a rectangular array of superimposed spots 15 as shown in Fig. 1, the spots are expanded to form abutting squares 21 as shown in Fig. 2. The screen 141 is photographed with a long exposure and the brightness of the spots (squares) depends on the number of superimposed spots occurring at each position during exposure, it being arranged that five superimposed spots cause saturation of the film. The squares are preferably arranged to abut, Gaussian noise being used with half peak noise amplitude corresponding to a point midway between adjacent spots. Instead of using noise to modulate the digital-valued pulses, a fast sawtooth may be used, but this gives the squares sharply defined edges and makes abutting difficult. In addition by using Gaussian noise rather than a repetitive waveform the distribution of illumination over each area matches approximately the response of the camera especially when it is used with a collimator having rectangular channels in register with the rib intersections. Instead of a two-dimensional array of counters a one-dimensional array may be used.

Abstract: 1317702 Printing apparatus POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 18 Jan 1972 2370/72 Heading B6C An offset rotary printing machine comprises four plate cylinders, four blanket cylinders and a single impression cylinder, and can be set either to make four impressions on one side of the paper, by independent co-operation of the blanket cylinders with the impression cylinder, or to make two impressions on each side of the paper by perfecting action of the blanket cylinders in pairs. The impression cylinder is attached to and driven by a gear 14, which is itself driven by a gear train 11-13. The blanket cylinders are attached to respective gears 20, 21, 24, 25, each of which meshes with a gear 19, 22, 23, 24 attached to a plate cylinder, and driving it. When the blanket cylinders co-operate with the impression cylinder, they are driven from the gear 14. When the printing machine is converted for perfecting printing each blanket cylinder is swung about the axis of its associated plate cylinder, so that the gears to which they are attached come out of mesh with the gear 14, and mesh together by pairs 20, 21 and 24, 25. The gear 14 also drives a train of gears 15, 16 to which two slidably-mounted gears 17, 18 are added to mesh with the gear 16, and also with gears 19, 23 attached to plate cylinders, so that each drives its own plate cylinder, two blanket cylinders and another plate cylinder. Registration of the two perfecting printing assemblies so formed is adjusted by means of the gear 17, which is mounted on an eccentric pin 31 and eccentric bush 29 so that it may be rotated without coming out of mesh with the gears 16 and 19.

Abstract: 1319909 Read only memory STANDARD TELEPHONES & CABLES Ltd 5 Aug 1971 36837/71 Heading G4A A read only store comprises a matrix arrangement which capacitively reads data from a punched card. A conventional 80 x 12 hole punched card is held tightly between conductive drive lines 1 aligned with the card columns on an upper printed circuit board and conductive sense and reference lines 2, 3 on a lower printed circuit broad by pins in holes 4. The sense lines are aligned with the rows of hole sites, the reference lines being aligned with the spaces between the rows and being broader than the sense lines so that where there is no hole, the capacitance between a drive and a reference line will be greater than that between the drive line and the sense line adjacent the reference line. If there is a hole the capacitance between the drive and reference lines is less than that between the drive and sense lines. Thus if the drive line is pulsed with a square wave the reference line signal will be less than the adjacent sense line signal if there is no hole, and vice versa. Drive pulses are applied sequentially to the lines 1 and a differential signal from the adjacent sense/reference pairs of lines is fed to a differential amplifier with negative feedback (Fig. 4, not shown). The small noise voltages produced can be reduced by adding an earthing conductor between the sense and reference lines (Fig. 3, not shown) or between the drive lines. The reference lines need not be made broader than the sense lines as the extra capacity to earth can be provided by external capacitors between the reference lines and earth.
