Title: Circuit interrupter
IPC: H01T1/14
Filed: 1961-05-23
Abstract: 919,788. Lightning arresters. WESTING- HOUSE ELECTRIC CORPORATION. May 23, 1961 [July 6, 1960 (2)], No. 18581/61. Class 38 (4). [Also in Group XXXVI] A lightning arrester is provided with a protective device in the form of an expulsion type circuit interrupter so that should the power follow current persist for longer than a predetermined period the earth terminal is expelled thereby disconnecting the arrester from earth. The circuit interrupter comprises a transparent insulating housing 40 having an annular region 44 of reduced cross-section which is easily fractured. An earth terminal 46 is carried in the housing 40 and is in contact with a flanged plate 52, the down-turned edge 54 of which bears on the thin portion 44 of the housing 40. A coil assembly 60 and a spark gap assembly 76 are electrically in parallel between the plate 52 and a second plate 84 which is in contact with the lower terminal 16 of the lightning arrester. The coil is wound on a spool 62 and is surrounded by a tube 64, both these members evolving gas when heated whilst the upper electrode of the spark gap is spring-loaded. When a surge is applied to the device the sparkgap 76 breaks down to complete a circuit to earth but should a current persist the coil 63 is vaporized, gas is produced by the members 62, 64 which puts pressure on the plate 52 to fracture the housing 40 in the region 44 whereupon the terminal 46 drops out to interrupt the circuit. A vent hole 16<SP>1</SP> is provided in the terminal 16 which vents the lightning arrester 10 when the terminal 46 has dropped out. The coil assembly may be wound in two coils concentric with one another or may be wound with turns having different pitches or of different gauge wire.

Four dies 12, Fig. 1, which also blank workpieces from strip 13, are mounted on a holder 17 movable by a ram 18 for co-operation with stationary cutting rings 59. Strip from a roll 14 is fed by rollers 15 and lubricated by rolls 16, An ejector 28 surrounds the die 12 and each die is associated with a separate ram 44. The chamber 49 is supplied with a constant volume of an incompressive fluid, e.g. oil, through a check valve (51), Fig. 2 (not shown), by a reservoir (50), a relief valve (54) being in a return line. A ring 67 onthe piston 41 surrounding a hub 66 on the piston 47 divides the chamber 49, leaving an annular throttle gap between the two through which movement of the hold-down pumps fluid with a resulting back pressure. The back pressure is reduced by at least one groove 77 in the hub 66 as the stroke progresses. Alternatively, conical zones may be provided on the hub, Fig. 8 (not shown).

Class 98(1) The apparatus, briefly, is designed for pushing a photographic assemblage carrying a fluid processing agent from a stack thereof in exposure position through pressure applying members to effect processing, and thus avoids the necessity of storing and operating leader strips and mechanically rotating rolls comprising the pressure applying members, as in the disclosures of Specification 788,488. It is adapted for pictures of 35 m.m. size or smaller, thus in Fig. 1 a camera embodying the invention and requiring only the depression of a plunger for full operation comprises forward section 12 with lens and shutter assemblage 14, rear section 16 comprising a film magazine removably secured to forward section 12 and a third section 18 serving as a processing chamber also removably secured to forward section 12. Photographic assemblages 42 in rear section 16 each comprising a rigid transparent print-receiving element 52 and opaque photosensitive element 54 with fluid container 56 in recess 60 therebetween as further shown in Figs. 6, 7 are urged by springs 44 into exposure position behind aperture 32 of wall 30 facing the lens, and when ready for operation depression of bar 106 constituting the plunger first operates the shutter through cam 134 and linkage 140 to expose the foremost assemblage, and then pushes the latter downwards through sprung pressure rolls 64, 66 to rupture the container and spread the processing fluid, normally to result in a positive image on print receiving element 52 through which the exposure was effected by transfer and reduction of unexposed silver salt from the photosensitive element 54; the assemblage attaining position in processing section 18 for the time required for transfer, after which the assemblage may be extracted through closure 90 and the photosensitive element 54 stripped off. Section 18 may be moved to an inoperative position shown in dash lines during the processing, or otherwise, to make the camera more compact, the necessary light-tight closures being provided. In another embodiment, Figs. 11-13 not shown, a manually engageable crank exterior to the camera is operated to depress the bar or plunger and a push button 110 at the top thereof as in Fig. 1 is omitted.

[Class 98 (i)] Screen material fluorescing yellowish-white, intended for discharge tubes such as Braun tubes, is produced from a mixture of highlypurified zinc and cadmium sulphides by adding traces of silver and copper in precise quantities, and calcining the mixture to effect crystallization. Relatively little cadmium sulphide is necessary-less than 30 per cent. The screen may be prepared by powdering a mixture of very pure zinc sulphide and very pure cadmium sulphide, intimately mixing therewith a mixture of sodium chloride, silver nitrate, and copper chloride, and calcining the product as by heating at 1000‹ C. to produce crystallization. Proportions for the ingredients are stated in the Specification, and the degree of purity of the sulphides is discussed. Reference is made to zinc sulphide activated with silver and copper.

Abstract: 212,185. Jackson, W. J. Mellersh-, (Soc. l'Air Liquide Soc. Anon. pour l'Etude et l'Exploitation des ProcÚdÚs G. Claude). July 23, 1923. Separating gaseous mixtures by liquefaction.- A rectification process for the separation of the constituents of air and the production of argon, by use of a principal and an auxiliary rectification column, consists in liquefying the air in a single combined vaporizer and liquefier provided with two separate compartments one of which supplies the gas ascending in the principal column while the other receives the oxygen finally cbtained from the auxiliary column and delivers it in gaseous form, the two compartments being traversed by a single nest of air liquefying tubes. The Figure shows means for effecting the process applied to apparatus shown in Fig. 3 of Specification 114,817. The auxiliary column B forms an extension of the main column A above it. The column A comprises in its lower part a vaporizer with two compartments C, D through which pass tubes F into which air is admitted at the inlet G, and in which this air is liquefied. The upper compartment C receives from the main column the descending liquid, which is rich in oxygen but contains argon; this liquid after partial vaporization descends through a tube H into the auxiliary column B. The liquid collecting at the bottom of this column is still richer in oxygen, and is delivered through a pipe K into the compartment D where it is completely vaporized, the resulting very pure oxygen passing off at the outlet L.

Abstract: Benzene hexachloride enriched in gamma isomer is obtained by crystallizing a mixture of the isomers from methanol containing water in an amount which is suitably between 1 per cent and 40 per cent by weight of the methanol.  Preferably the weight of water added is that given by the equation P=a log10R/k where P is the weight of water, a is an integer between 35 and 45, k is equal to 1 minus the fractional yield of gamma isomer that is desired based upon the gamma isomer content of the crystallizer feed and R is the ratio RC/RE where RC is the ratio of methanol benzene hexachloride in the crystallizer feed after concentration and RE is the ratio methanol benzene p hexachloride in the original solution prior to concentration, e.g. in the crude benzene hexachloride extract.  Examples of the crystallization of benzene hexachloride according to the invention and comparative examples of crystallization from methanol alone are given.
