Title: Current regulators
Inventor: PAICE DEREK ALBERT
Filed: 1961-11-07
Abstract: 988,585. Automatic control of current and voltage. ROTAX Ltd. Oct. 31,1962 [Nov. 7,1961], No. 39782/61. Heading G3R. In a current regulating circuit having input terminals 5, 6 and output terminals 7,8, a currentdependent voltage is derived from transductors 13,14,oscillator 17,rectifier 18 and resistor 19 and is applied to a capacitor 26 connected to the base of a transistor 21;when the voltage across the capacitor 26 exceeds a reference voltage, determined by a Zener diode 22 connected to the emitter of transistor 21,the transistor conducts so that a control switch 10, connected between terminals 5 and 7, is rendered non-conductive,whereby the current in the circuit is maintained constant. To minimise the possibility of high currents when the circuit is initially switched on, a timedelay switch 9 ensures that no load current flows until a predetermined period has elapsed, during which time the capacitor 26 charges up to the reference voltage by way of a resistor 24 and a diode 25, whereby the circuit is ready to operate immediately switch 9 closes. Voltage regulation may be effected by connecting the capacitor 26 to the terminal 7 by way of a diode 27, so that the capacitor is charged to the output voltage or to the voltage across resistor 19,whichever is the higher.

Abstract: 1,186,164. Toothed gearing; friction clutches. MARWIN MACHINE TOOLS Ltd. 29 Aug., 1967 [6 Sept., 1966], No. 39832/66. Headings F2C and F2Q. In a gear-box comprising two parallel gear trains, back lash in the gearing is eliminated by having one gear 25, in one gear train, rotatably journalled on a shaft 27, the gear 25 having cam faces 40 which are engaged by rollers 42 mounted in the ends of pistons 44 disposed in a drum 46 which is keyed to the shaft 27. On the application of hydraulic pressure through tubing 54, the pistons move out of the drum 46, and the effect of the rollers 42 bearing on the cam faces 40 is to rotate the gear 25 and shaft 27 in opposite directions and to preload the gear train with a torque which is greater than that to be transmitted. In a modification, the pistons have their axes located in a plane transverse to the axis of the shaft.

Title: Improvements in or relating to photographic processing apparatus
Inventor: HOLLOWS JACK
IPC: G03D3/13
Filed: 1958-12-11
Abstract: 863,513. Photographic processing apparatus. UNIT TOOL & ENGINEERING CO. Ltd. Dec. 10, 1959 [Dec. 11, 1958], No. 39948/58. Class 98(2) Apparatus for processing photographic paper comprises a spool or spools for carrying a roll or rolls of paper, a series of tanks each for holding liquid, guide and feed means for engaging the paper and progressing same through the tanks, an endless belt guided into and out of the tanks, means for attaching the leading end of a roll of paper to the band for initiating the passage of the paper through the tanks and engaging it with the feeding means, and driving means for actuating the belt and the feed means in such a manner that the rate of feed of the paper is in excess of the rate of travel of the belt. As shown tanks 11, 13, 14, 15, 16 and 17 are provided respectively for developing, rinsing, fixing and washing the endless belt 18 passing over the tank 11 but through the remaining tanks and being drawn by rollers 19, Fig. 1, driven by chain and sprocket from an electric motor 22. In the apparatus described rolls of paper may be processed simultaneously, being driven by rollers 28, Fig. 3, coaxial with the rollers 19 and driven Ly the motor 22 at a faster rate than the rollers 9. The paper x is carried on a spool 32. To thread the paper into the apparatus its free end is attached to the endless belt and as it is passed over the tank 11 it is guided into it by a rod 33 carrying a roller 35, the time of development eing determined by the depth to which the rod inserted. As the paper continues to be drawn by the endless belt it is guided thereby into engagement with the driven rollers 28 and is fed thereby at a faster rate than it is moved by the belt. Consequently the paper adopts a zig-zag crientation in the tank 13, as shown, and as it continues to be drawn through the other tanks it adopts a similar orientation therein. On emerging from the tank 17 the end of the paper is detached from the belt and passed through suitable drying and glazing apparatus to a takeup spool, the paper continuing to pass through the tanks in the manner shown until all is processed.

Abstract: 928,236. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Nov. 20, 1961 [Nov. 22, 1960], No. 40084/60. Class 39 (4). A nuclear reactor is cooled and moderated by an organic liquid which makes two passes through the core, the first pass extending in close proximity to the fuel and having a lower polymer content than the second pass which is separated from the first by dividing means, and restrictor means are provided in the second pass to equalize pressure across the dividing means. The first pass, which contains about 30% of a terphenyl polymer of high molecular weight, cools the fuel sealed in the cartridges 1, which are spaced on a triangular pitch lattice, enters the compartment 5 and is circulated by the pump 11 through the heat exchanger 14. The more viscous second pass, containing about 50% of the polymer, acts as a moderator and is restricted in its passage through the compartment 6 by baffles 6a which introduce a pressure drop in the compartment. To purify the moderator which has deteriorated, the tapping 17 leads some of the liquid to the distillation column 18, and purified distillate is returned into pipe 10. Waste products are dumped through pipe 20. The distillation column may be provided with means for connecting it into the moderator or coolant circuit as required. A further tapping 21 leads the liquid from the near stagnant region of the coolant circuit to the second circuit.

Title: Half-tone prescreened photographic material
IPC: G03F5/00
Filed: 1961-11-10
Abstract: 923,226. Half-tone prescreened photographic material. EASTMAN KODAK CO. Nov. 10, 1961 [Nov. 14, 1960], No. 40323/61. Drawings to Specification. Class 98 (2). A supported silver halide emulsion layer which shows at least 0.3 logarithmic exposure units of Clayden sensitivity at 20‹ C. with an exposure of one millisecond duration is cooled to below -10 ‹ C. and exposed to a half-tone light pattern so that areas of maximum desensitization show at least 0.6 logarithmic exposure units of Clayden sensitivity. Preferably, a temperature of below - 40 ‹ C. by dry ice or liquid air cooling is used, and the method results from the discovery that the Clayden effect is enhanced at these temperatures, and that the exposure therefor may be increased as from 1/1000 to ¢ second, which lends itself to continuous prescreening. A single film or plate may, however, be so treated with exposure through a ruled screen at half-tone distance with a flash lamp, or else a tungsten lamp for up to one second, to give an undulating screen pattern; and in the continuous procedure the emulsion passes over a transparent roller carrying a contact screen and having an internal lamp, at a rate to give a ¢ second exposure. Specification 534,593 is referred to.

Abstract: 1,000,948. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. Nov. 17, 1961, No. 4120/61. Heading H1K. A composite block of material comprises a photo-voltaic cell consisting of semi-conductive material of high energy gap powering a device consisting of semi-conductive material of low energy gap. As shown, the photo-voltaic cell comprises P+ and N+ layers 10, 11 of silicon and formed integrally with a four-layer switching device 12, 13, 14, 15 respectively consisting of P+, N, P, N+ germanium. The regions 13, 14 are insulated from the region 11 by a layer 16 of intrinsic silicon. The larger energy gap of the silicon enables the photo-voltaic cell to provide an adequate sustaining voltage for the four-layer switching device. The device may be fabricated by epitaxial growth (e.g. for the germanium silicon transitions) and diffusion (e.g. for the junctions). The four layer diode may be of silicon-germanium alloy in which case the whole device may be provided with a surrounding silicon dioxide layer by oxidation. Otherwise such a layer may de deposited by evaporation. In operation the device is activated by illumination of layer 10 and switched on by a pulse applied capacitatively to layer 13. A suitably coupled coil can detect transistions between the on and off state. The off state is achieved by reducing the level of illumination. Other materials may be gallium arsenide (high gap) and indium antimonide (small gap). Specification 900,959 is referred to.
