Patent GB-640207-A (GB)
Title: An electrical battery charge indicator
IPC: G01R31/36
Filed: 1948-02-23
Abstract: 640,207. Electromagnetic ammeters and voltmeters; battery charge indicators. GRUCHY, J. N. DE, and EVERETT, EDGCUMBE, & CO., Ltd. Feb. 23, 1948, No. 5240. [Class 37] A battery charge indicator is responsive to a main torque proportional to battery terminal voltage and an assisting compensating torque variable in terms of battery internal resistance or battery voltage and related to the volt drop in the battery due to load current. As shown, a moving coil 1 is connected through a resistance 3 across the battery terminals so that the torque on coil 1 is proportional to battery terminal voltage, and a moving coil 2 secured to coil 1 is connected across a resistance 5 in the load circuit and acted upon by a torque proportional to battery volt drop whereby the total instrument torque is the sum of the torques on both coils and pointer 6 is deflected in accordance with battery E.M.F. The polepieces 7 associated with coil 2 are arranged to produce the required degree of field distortion so that the torque on coil 2 varies to take account of changes in battery internal resistance. In the alternative arrangement (not illustrated) a high torque voltage indicator operates a light contact variable resistance element to increase the current flowing in the compensation circuit at a given load as the battery voltage decreases. Contacts may be fitted to the indicator system to open or close at some predetermined battery E.M.F. and thereby alter the load conditions. It is stated that if a moving magnet or moving iron instrument is employed the compensating coil would be positioned so that it exerts a greater torque on the moving element for a given excitation current when the voltage indicator tended to a lower voltage reading.

Title: The production of organo-silicon polymeric compounds
IPC: C08G77/50
Filed: 1941-04-28
Abstract: 552,640. Resinous organo-silicon compounds. BRITISH THOMSON-HOUSTON CO., Ltd. April 28, 1941, No. 5449. Convention date, April 30, 1940. [Class 2 (iii)] Resinous, polymeric organo-silicon compounds, having contiguous silicon atoms linked by divalent organic radicles and also by oxygen atoms, are obtained by hydrolysis and dehydration of an organo-silicon halide obtained by reaction of a silicon halide with more than 1¢ and less than 2 mol. equivalents of a dimagnesium derivative of an organic dihalide. Alternatively, a di-magnesium derivative may first be reacted with silicon halide and the resulting organo-silicon dihalide further reacted with an organic magnesium halide, the amount of magnesium halide being insufficient to react completely with the halide attached to the silicon, the product being then hydrolyzed and dehydrated. Dehydration may be effected in the presence of dehydrating agents, as described in Specification 549,081. Mixed products may be obtained by mixing different polymers or by mixing different starting materials. The polymers may also be modified by incorporating the polymers or partial condensation products described in Specifications 542,655 and 544,143. The products may be applied, alone or compounded with other materials, as described in Specifications 542,655 and 544,143. In an example, ether solutions of phenylene dimagnesium bromide (1 mol.) and silicon tetrachloride (1.32 mols.) were slowly mixed and then heated under reflux to produce a phenylene silicon dichloride, an ether solution containing 1.26 mols of methyl magnesium bromide per mol. of phenylene silicon dichloride was slowly added, with stirring and the reaction mass poured on to cracked ice to hydrolyse the methyl phenylene silicon chloride, after which the ether solution was separated, washed free of acid and the ether evaporated leaving a soft, sticky resinous material which, by further heating at 120‹ C. yielded a soft resin soluble in benzene, toluene and acetone ; in a further example, the dimagnesium derivative of mixed dichloropentanes is employed in place of the methyl magnesium bromide.

A rotary valve comprising a plug 16 with part-spherical portions and cylindrical extensions 14, 15 mounted in a transverse bore 2 of the valve housing 1 and formed with annular grooves 17, 18 carrying sealing rings 19, 20 has an annular sealing piston 27 associated with each of the fluid flow connecting pieces 6, 7 which are screwed into the valve body 1 and locked by screws 8, 9, the sealing pistons 27 being arranged to be pressed against the plug by the pressure of the controlled fluid. The face of each piston 27 remote from the plug 16 forms, together with the body 1 and the corresponding connecting piece, a groove of rectangular crosssection in which is mounted an elastic sealing ring 35 of greater cross-sectional diameter than the axial dimension of the groove. Each piston contains a sealing ring 38, e.g. of rubber or synthetic material such as an ethylene polymer containing fluorine, for engagement with the plug. Pressure fluid at the inlet of the valve passes between interengaging surfaces of the corresponding connecting means and the annular piston to urge the sealing ring 35 radially outwardly to form a seal with the body 1. Any fluid leaking to the central chamber of the valve has access to the sealing ring 35 of the other annular piston to urge it radially inwardly to form a seal. The valve is actuated by a lever 22 engaging a squared extension 21 of the plug which carries a recessed abutment disc 23 coacting with a fixed pin 24 to limit the rotary movement of the plug. In modifications, the groove containing the sealing ring 35 is bounded wholly by the connecting piece and the annular piston instead of in part by the body 1 as shown. In one of these modifications the sealing ring is contained in a groove bounded by a spigoted part of the connecting piece entering counter bores in the annular piston, whilst in other modifications an annular groove in either the connecting piece or the annular piston contains the sealing ring 35 and is engaged by a projecting annulus on the other member.

IPC: C22B23/02
Filed: 1918-04-11
Abstract: 122,335. Marks, E. C. R., (United States Nickel Co.). April 11, 1918. Nickel chloride and sulphate.-Copper-nickel matte is roasted until it contains 8 to 12 per cent of sulphur, and is then reduced by gases, coke, or other means. If the matte is sufficiently low in sulphur, the roasting step is unnecessary. The reduced product is leached with sulphuric or hydrochloric acid or copper sulphate to dissolve the nickel and nickel sulphide without dissolving the copper. Some of the partially roasted matte or some metallic nickel may be added to prevent solution of copper or to ensure precipitation of any copper which may have been dissolved. The solution of nickel salt may be treated in any way for the extraction of nickel, for example by the addition of lime and the subsequent reduction of the hydrate. Specifications 17974/94 and 15850/11 are referred to.
