Title: Improvements in or relating to electrical switch gear
IPC: H02B13/02
Filed: 1920-06-22
Abstract: 169,280. Coates, W. A., Davies, D. R., and Metropolitan-Vickers Electrical Co., Ltd. June 22, 1920. Electric switches etc.; oil switches; bases, boxes, and cases; switches, actuating.-Relates to an arrangement of ironclad switch gear of the type in which a cable is adapted to be connected by a main oil switch through isolating and selector switches, and in some cases through an instrument and other series transformers to one or more sets of bus-bars, all such devices with their interconnecting leads being enclosed in metal cases, some of which are filled with oil and others with solid insulating-material. Figs. 2 and 3 show an application to a three-phase alternating-current system with split-conductor protection. The main and auxiliary bus-bars 4, 5 are supported within a metal casing 20 with an opening 23. The isolating and selector switches 7, 16 of the plug-and-socket type are arranged side-by-side horizontally, and are disposed within tubes 49 of insulating-material in a metal chamber 25. The chamber 25 communicates at the front with the opening 23 of the bus-bar chamber 20, and extends as far as the oil switch 3. The plungers of the isolating and selector switches 7, 16 are connected by rods 27 of insulating-material to the operating-mechanism consisting of a screw and nut 28 operated by a handle 31 through bevel-gear 30. The casing 25 may be integral or built up of sections, partitions 26 being provided between adjacent phases. Below the chamber 25 is supported the transformer chamber 48, containing split-conductor and series transformers 9, 10. All inter-chamber connections consist of copper rods 41, 46 in insulating-tubes 42, 47. Connections within the chambers consist of strip conductors 40, 45, while strip conductors 43 in insulating-tubes 44 pass between the casing 25 and a metal chamber 35 supported within the top of the oil switch 3, in which casing the strip conductors 43 are joined to the poles 11 of the oil switch. The incoming leads 1 are sealed at 22 at their point of entry into the bus-bar chamber 20, being divided within the chamber, the cores 2 being connected to strip conductors 24 attached to isolating switch terminals 7. Strip conductors 18 join the terminals 16 of the selector switches to the main or auxiliary bus-bars 4, 5. The potential transformer 52 in the metal casing 51 is supported on a base 50 formed on the casing 25. The above arrangement provides a means whereby the necessary oil insulation of the switch gear is reduced, the isolating and selector switches as well as all the electrical leads, the bus-bars and fixed joints and the metallic terminals of the isolating and selector switches being surrounded by solid insulating-material. A modified arrangement of switch gear is also described in which the isolating and selector switches are arranged side by side vertically, the lower contacts of these switches projecting into the bus-bar chamber.

Patent GB-1537307-A (GB)
Title: Gated oscillator
IPC: H03L3/00
Filed: 1976-04-29
Abstract: 1537307 Gated astable multivibrator RCA CORPORATION 29 April 1976 [2 May 1975] 17459/76 Heading H3T A gated astable multivibrator is controlled such that the first pulse generated after turning on is equal in duration to that of the subsequent pulses. At oscillator off, the base of a transistor 21 connected to a node 51 within the multivibrator is connected via transistor 20 to the positive voltage thus initializing the node. At turn on transistor 20 is turned off and a stored charge removal circuit 4, 6 is turned on to discharge the parasitic capacitances. The multivibrator is substantially that of Specification 1,416,931. Oscillations occur when the input signal applied to terminal 2 is low. when the input is high the NAND 24 and the transistor 21 prevent oscillations, the latter clamping one side of the capacitor 27 to +V DD  while the other side is held low by the inverter 25. At the instant that the input at 2 goes low to start oscillations clamping is removed from point B and the NAND output goes low, inverted by 25, this applies a step voltage to the capacitor and point B rises to 2 V DD . The charge decays with the time constant set by capacitor 27 and resistor 28 until the converter 22 changes state and the whole loop 23, 24, 25, 26 and the output 40 follow suit. Without the low impedance path 4, 6 the parasitic capacitances would discharge via transistor 21 and the extra charge would prolong the first period beyond the intended value.

Title: Process for producing sulphur by means of reduction of sulphur dioxide
IPC: C01B17/04
Filed: 1934-06-13
Abstract: <PICT:0426165/III/1> In the production of sulphur by the gaseous reduction of sulphur dioxide, the reduction is effected in a chamber so constructed that the sulphur dioxide is introduced in counter current to and is preheated by the reaction gases.  As shown, the reducing gases enter by a pipe 2 at the top of the reaction chamber and mingle with the sulphur dioxide gases delivered by a centrally situated pipe 1<a> up which the gases pass from a pipe 1.  As the reaction is exothermic, heat is given up by the reaction gases in their passage to the exit pipe 3.  In a modification, the reaction gases pass down the centre of the chamber and sulphur dioxide passes up the exterior space, the central portion being filled with contact material, e.g. brick, coated with a catalyst, e.g. iron or an iron compound or an alkali compound.  Fresh powdered catalyst may be supplied from a hopper 4 during the process.  As reducing gas may be employed producer gas or blast furnace gas and in the case of producer gas, sulphur dioxide may be fed to the producer; powdered carbon may also be used as the reducing agent.

Photographic exposing and developing apparatus comprises exposure means for exposing successive areas of a light-sensitive sheet 24, the exposure means being adjustable to vary the length of sheet exposed; processing means for applying liquid to successive sections of the sheet, each section including an exposed area; and control means coupled with the exposure and processing means for varying the length of each section in proportion to the length of the associated exposed area. A document to be exposed is placed face down on the transparent wall 10 of a chamber 12 containing lamps 14 and reflectors 16, and is imaged via a lens and shutter system 22 and a mirror 30 on to the area of the sheet 24 which is held between a support plate 26 and a transparent plate 28. To prevent stray light reaching the sheet 24 an adjustable curtain 35 is provided so as to leave uncovered an area of the plate 28 corresponding to the area of the original adjustment being effected by hand using a disc 42. Movement of this disc also adjusts the position of a micro-switch 100 on a shaft 82 so that the switch is tripped by the leading end of an exposed processed section after a time depending on the length of the section. Tripping the switch causes a knife 50 to sever the trailing end of the section. Processing liquid is applied to the section by a roller 56, and excess liquid is removed by rollers 76, 78 before the section is carried between belts and rollers and then passed out of the apparatus at 92. The processing liquid may be supplied in a container (94, Fig. 4, not shown) and dispensed in controlled quantities by a solenoid operated valve 96 into a trough into which the roller 56 dips. A variable timer (98, Fig. 7, not shown) controlled by the disc 42 or by a half disc (104, Fig. 4, not shown) in turn controls the time for which the valve 96 is open. In the embodiment of (Fig. 4), the half disc (104) mounted on the shaft 82, replaces the disc 42, and the curtain 35 is replaced by a curtain (135) which covers part of the wall 10.
