Title: Improvements in or relating to electric circuit-breakers
IPC: H01H3/32
Filed: 1930-03-11
Abstract: 350,046. Automatic circuitbreakers. REYROLLE & CO., Ltd., A., Hebburn-on-Tyne, and MIRREY, J., Cairnsmore, Osbaldeston. Gardens, Gosforth, Northumberland. March 11, 1930, No. 7956. [Class 38 (v).] Switches, actuating; latching and unlatching.-A circuit-breaker has a spring interposed in the mechanism for transmitting a closing force to the contacts, which spring acts when stressed beyond a predetermined extent during closing operations to effect an interruption in the transmission of the closing force, whereby the breaker opens instantaneously and prevents damage to the operator's wrist or other closing agency when the breaker is closed on to a shortcircuit giving rise to large electromagnetic forces. The switch is closed by rotating the handle F, together with the lever G to which it is pivoted at F<1>, about the axis C of the lever G until the position shown in Fig. 4 is reached, whereupon a shoulder H<2> on a lever H, which is pivoted at H<1> to the lever G, engages behind a roller D<1> carried on a U-shaped bracket D, the limbs of which are keyed to the shaft C. The handle F is then moved back to the position of Fig. 1 where it, with the lever G, is latched by a latch L to a fixed stop C<2>. During this movement, a pair of adjustable compression springs E mounted between the underside of the bracket D and a part E<1> formed on a carrier B, free on the shaft C, cause the carrier B to rotate and pull on a rope A<2>, whereby the contacts A are moved to closed position against the action of a spring A<1>. A trip lever K, pivoted at K<2>, is formed with parts K<5>, K3 for manual and automatic tripping by, respectively, the backward movement of an extension F<4> of the handle F, and the overload coil K<4>. In both cases, the lever K is rotated so that an extension K<1> thereon engages the end H<3> of the latch H to move the shoulder H<2> free of the roller D<1> and allow the spring A<1> to move members A, B, D to open-circuit position. In this movement a pin C<3> on the shaft C deflects the latch L ready for another closing operation. If the switch is closed on a short-circuit, a strong electromagnetic force opposes the closing force and causes the springs E to become so compressed that tripping levers J, pivoted to the member D, are rotated by engagement between the member B and projection J2, until a pin J<1> interconnecting the members J engage the lever H and deflects it, so allowing the switch to open. Arrangements are provided for preventing operation of the emergency trip devices in the fully-closed position, to prevent operation by surges. The Provisional Specification describes also a switch operated by the pressure-wave set up in the oil when closure on to a short-circuit takes place.

Title: Method of stabilizing plastic polymers of halogen-2-butadienes-1, 3
IPC: C08K5/42
Filed: 1937-03-19
Abstract: Plastic polymers of halogen-2-butadiene-1 : 3 which are capable of being cured by heat to the strong elastic state resembling vulcanized rubber are stabilized by mixing with an organic mercaptan of the type Y-R1-SH where R1 is aryl or aralkyl and Y is hydrogen or one or more of the following groups: Cl Br, I, NO2, or SO3M where M is hydrogen or an alkali metal, but the mercaptan should not contain as substituents COOH, NH2, a second SH, OH or alkoxy group.  The preferred mercaptans are nitrothiophenols or thionaphthols.  The amount of the stabilizer may be 0,1-5 per cent, preferably 1-2 per cent. When the polymer has been prepared in the presence of an aromatic mercaptan, the stabilizer is added in quantity sufficient to bring the content within the limits defined.  Examples contrast the properties of polymers produced by polymerizing chloroprene in acid emulsion in the presence of thioglycollic acid and hydrogen sulphide (a) when phenyl-beta-naphthylamine alone, and (b) when phenylbeta-naphthylamine and thiophenol and paranitro thiophenol respectively are mixed with the polymer.  Other stabilizing compounds mentioned are o, m, and p-thiocresol, thio-a -and b -naphthol, o- and m-nitrothiophenol, dinitrothiophenols, o- and p-mercapto-diphenyls 1- and 2-mercapto-anthracene, chloro, dichloro and trichloro-thiophenols, dibrom-thiophenols, iodo - thiophenols, thiophenol sodium sulphonates, thio-xylenols, mercapto-diphenyl potassium sulphonates, mercapto-anthracene sulphonic acids, dinitro-thionaphthols, benzyl and nitrobenzyl mercaptans, and chloro-b -phenyl ethyl mercaptans.  Specifications 387,363, 497,420, and 497,638 are referred to.  The Specification as open to inspection under Sect. 91 states that the stabilizer may be an alkyl mercaptan which may be substituted in the manner stated above for the aryl mercaptans.  This subject-matter does not appear in the Specification as accepted.

Title: Anode tube for high voltage ionic valves
IPC: H01J17/04
Filed: 1951-04-10
Abstract: 691,151. Metal-vapour converters.. ALLMANNA SVENSKA ELECTRISKA AKTIEBOLAGET. April 10, 1951 [April 21, 1950, No. 8270/51. Class 39(i). In a high voltage ionic valve in which the anode tube 1, 'Fig. 1, is of ceramic material, preferably porcelain, and contains a plurality of sheet metal bodies between the anode and the cathode space which carry different voltages for obtaining an appropriate potential distribution during the non-conducting intervals, each conducting body has a peripheral portion 5, 6 a central portion 2 comprising a closed or almost closed cavity surrounding the current path or paths and an intermediate portion 4 having no closed cavities formed therein. In one form, Fig. 1, six sheet metal 'discs' preferably of iron are arranged between the anode and cathode and are formed with central box shaped portions 2 which may or may not be entirely closed, i.e. flange 9 may or may not extend to part 4, and which surround channels 3 arranged in a circle for the passage of the discharge and intermediate portions 4 and outer portions 5, 6, forming tortuous passages therebetween to impede the flow of ions to the tube wall. Current leads are taken through wall 1 as shown. The rings 5 are so close to the tube wall that no discharge can pass between the rings and the wall. One or more of the discs adjacent to the cathode space 7 may serve as control grids or draw starting arcs. In a modification, Fig. 2 (not shown), the intermediate portions of the discs are formed as double conical surfaces whose relative dimensions vary from one disc to another, except for the two end discs whose intermediate portions are formed as a single conical surface. In this way the discs are more widely separated at their peripheries than at their centres which improves heat dissipation. The peripheries of the discs have folded edges for securing them to the tube wall. It is stated generally that the intermediate portions of the discs may be shaped to give the channels between them one or more bends, and may be all of single cones.

The safety device comprises a locking plunger 10 biased by spring 11 into engagement with a cam 13, the cam being located on the rotor operated by key 2. The plunger 10 is withdrawn from the cam by an electromagnet 12 supplied via an oil pressure switch 15, (opened under oil pressure from the engine when running) and switch 4 operated by the rotor. The projection 37 is arranged to operate, between off and on positions, a decompression or a fuel control device 33 from a remote control 38 dependent on direction of rotation of the cam. Under normal conditions cam rotation in direction F2 moves the device 33 so as to stop the engine. Switch 4 is in the closed position and switch 15 closes when the engine stops. This withdraws the plunger clear of cam face step 13' and allows the cam to be rotated to the 'locked' position. If the engine fails to stop, the plunger is not withdrawn and the cam cannot be returned. In the OFF position, switch 4 opens to release the plunger to rest on the cam surface. Actuation of the cam in the direction Fl causes the engine lock to be released, switch 4 closed and the plunger withdrawn, lever 33 to move to the engine operable position and finally the engine to start. Rising oil pressure then opens switch 15 and the plunger engages the cam in the protecting position.
