Abstract: 899,075. Drawing curtains. HALL STAGE EQUIPMENT Ltd. Dec. 14, 1959 [Dec. 18, 1958], No. 40906/58. Class 52(5) Each pair of runners 13 of a stage &c. curtain is connected by a pair of links 18, 19 pivoted thereto and to each other to form an inverted V the apex of which is held down by a cam rail 21 except at the end towards which the curtain is drawn so that, as the curtain is drawn open, it can only bunch at that end.

Abstract: 1,115,873. Electrophotography. EASTMAN KODAK CO. 27 Sept., 1965 [25 Sept., 1964], No. 40926/65. Heading H1K. [Also in Division G2] An electrophotographic material comprises an electrically conductive support coated with a zinc oxide layer having a superficial layer of zinc ferrocyanide or ferricyanide. The zinc oxide may be dispersed in an insulating binder, preferably a copolymer of styrene and butadiene or a mixture thereof with a silicone and a petroleum resin. Other binders such as polystyrene, cellulose nitrate, polyvinyl butyral, polyvinylidene chloride, chlorinated rubber and rubber hydrochloride may also be used. The support may be aluminium or conductively coated glass, paper or plastics. The layer of zinc ferro- or ferri-cyanide may be obtained by spraying, dipping or spreading the zinc oxide with an acidic solution of a ferro- or ferricyanide, e.g. potassium ferrocyanide. Alternatively, separate applications of zinc sulphate and potassium ferrocyanide may be applied to the layer.

Abstract: 1,123,259. Control systems for consumption apparatus. HONEYWELL Inc. 27 Sept., 1965 [2 Oct., 1964], No. 41046/65. Heading H2H. [Also in Division H3] Current from an A.C. source to a load is controlled from an A.C. control signal by rectifying the latter and applying it to a trigger circuit having hysteresis; the output of the trigger circuit is applied to a control stage which operates a switch between the source and the load. In the Figure an A.C. control signal 70 is applied to rectifiers 75, 81 to charge up capacitors 78, 82 with the polarities shown. The voltage across capacitor 78 turns on transistor 65 and conduction of this holds off transistor 60. When the magnitude of the control signal exceeds a certain level, Zener diode 89 will conduct, and the voltage across capacitor 82 causes a current to flow through resistor 86 in the opposite direction to that from capacitor 78, thus turning off transistor 65. Transistor 60 then turns on, passing curront through resistor 46. If the magnitude of the control signal 70 is reduced, transistor 65 will conduct when the combined voltage across capacitor 82 and resistor 86 falls below a certain level, thus introducing hysteresis. Current flow through resistor 46 allows a controlled rectifier 40 to pass current from a diode bridge 33-36 to turn on reverse-parallel connected thyristors 20, 25. These conduct on alternate cycles of the supply 10 and allow current to flow through the load 11. The Zener diode 89 may be replaced by a neon tube.

Abstract: 1,131,566. Metal-vapour lamps. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 16 Sept., 1966 [21 Sept., 1965], No. 41423/66. Heading H1D. A low-pressure mercury vapour lamp having thermally-emissive electrodes 5 contains an amount 13 of metal which can form an amalgam with mercury located in a region of the lamp, the temperature of which during operation of the lamp is not directly influenced by the temperature of the electrodes, and also contains a further amount of metal 11 which can form an amalgam with mercury located adjacent an electrode on a member 7 the temperature of which is directly influenced by the temperature of the electrode after switching on the lamp. The metal 11 may be such that it forms an amalgam which, at the same temperature, has a lower vapour pressure than the metal 13, e.g. the metals may be respectively indium and cadmium. Other metals which may be used are thorium, gallium and zinc. When the lamp is switched on, the amalgam 11 on member 7 reaches a high temperature quickly and the mercury from it is evaporated completely. Thereafter, the required mercury-vapour pressure of from 4 to 10 microns is determined by the amalgam 13 as it becomes heated by the discharge. The supporting members 7 consist of metal rings electrically insulated from the electrodes. The lamp is provided with a luminescent layer 2.

Abstract: 894,229. Drying grain &c. STEWART, R. B. Dec. 15, 1960 [Dec. 15, 1959], No. 42617/59. Class 34(2) In an apparatus for drying grain &c., the grain is fed progressively to the top of two substantially vertical drying chambers of rectangular crosssection, two opposing walls in each chamber being perforated or louvred for the passage of a drying gas or heated air in a horizontal direction therethrough, allowing the grain to pass downwardly under gravity, the rate of displacement being controlled by an oscillating damper disposed at the base of each chamber, the volume of grain so displaced being governed by the period of oscillation and the angle of incidence of the dampers, means for conveying the grain discharged from the first chamber to the top of the second chamber, ensuring that both chambers are constantly filled to a level above that of the perforations in the walls, means for regulating the volume of dried grain discharged from the second chamber, and means of synchronizing the volume of partially dried grain displaced from the first chamber with the rate of feed required to maintain the correct level in the second chamber. The drying apparatus comprises drying towers 1, 2, Fig. 1, having perforated side walls 4 . . . 7 through which hot air from a plenum chamber horizontally flows through the material as it flows downwardly under gravity from a hopper 8 at the top of the first tower for discharge through a slot 9, controlled by a pivotable damper 10 which in turn is controlled by a tamping arm 11, for passage to a V-shaped hopper 13, duct 14 and chamber 15 from which it is both mixed and conveyed in an elevator 16, shoot 17 and hopper 18 to the second tower 2 for further drying and discharge through a slot 23 controlled by a damper 22. The tamping arm regulates the damper 10 to control the flow of granular material from the tower 1 in accordance with the amount of material in the hopper 13 by a shoe 30, Fig. 3, on the arm abutting the surface of material therein. The surface level in the hopper 13 is dependent on the amount of material remaining in the chamber 15 which, in turn, is regulated by the volume of dried material discharged from the tower 2 since material fed to the tower 2 by the elevator 16 in excess of requirements is returned to the chamber 15 via a weir 19 in the hopper 18 and an overflow duct 20. The damper 10 is pivotally mounted about a horizontal axis and is connected by an arm 23, Fig. 3, to the tamping arm 11, which is raised and lowered by a shaft 29 through a chain and sprocket 27, 28 so as to regulate the angle of the damper 10 in accordance with the level of material in the hopper 13. Cooling air may be introduced into a further tower (not shown) prior to discharge of the dried material and semi-saturated air discharged from the drier may be recirculated.

In jointing of square-section pipes 1 shown in Fig. 1, a torch 2, energized, is moved forward (from left to right) with the pipes stationary so as to weld along one side of the pipes, and then the torch is moved back (from right to left) while the pipes are rotated, through 90 degrees, either clockwise or, as shown, anticlockwise to bring the torch and pipes into position for the next weld section. The torch is maintained at a constant distance from the workpiece as by an electromechanical constant arc length system. In Fig. 2, a torch carrier 15 is reciprocated by forward and reverse rotation of a screw 14 which is driven by an electric motor 25 via a 2-speed reverse gear 3.
