Filed: 1932-02-09
Abstract: 396,751. Accumulators. LEVY, L. A., 31, Shoot-up Hill, Cricklewood, and ALMEIDA ACCUMULATORS, Ltd., 53, Great Marlborough Street, Regent Street, both in London. Feb. 9, 1932, No. 3879. [Class 53.] An accumulator in which zinc is deposited on charging has positive plates a consisting of graphite surrounded by carbon granules or powder held together in plate form by gelatine, glue, &c. which dissolves in the electrolyte when the cell is assembled. The compressed granules or powder are held in position by a wrapping e of asbestos cloth the ends of which are stuck or stitched together. Stitching is also passed through the graphite plates from one face of the wrapping to the opposite face. The upper ends of the plates are fitted into slots in a carbon block h to which is screwed a metal bar carrving a terminal lug k. Glass strips m of U-shape prevent access of electrolyte to the block h. The bar j and lug k are enclosed in a protective material such as a mixture of bitumen and ozokerite. The negative plates o are also made of graphite and are clamped together against graphite separating blocks q and zinc connecting strips r by means of bolts s. The strips rare connected to a bus-bar t carrying a terminal lug u. The electrolyte contains zinc bromide, zinc chloride, potassium acetate, lithium chloride or bromide and hydrochloric acid. Mercuric chloride may also be added to amalgamate the zinc and instead of the lithium salts the chlorides and bromides of magnesium, sodium and beryllium may be used. Sufficient electrolyte is used to allow of free circulation. Instead of the asbestos wrapping for the positive plates a covering in the form' of a braided tube may be used which may be woven on to the plates. In a modification the positive plates are clamped against carbon blocks w by a bolt, the carbon blocks being clamped to the bus-bar j, Fig. 18, by screws v. U-shaped metal strips z make connection between the bar j and the carbon blocks. Specifications 298,289, 320,916, 321,405, and 324,918, [all in Class 53, Galvanic batteries], are referred to.

Title: Hydraulic starter system for internal combustion engines
IPC: F16H39/00
Filed: 1956-02-14
Abstract: 821,528. Engine turning gear. BISHOP, M., LIPTON, L., and LIPTON, J. Feb. 14, 1956, No. 4549/56 Class 7(5) [Also in Group XXIX] The invention relates to a rotary starter connected through a control valve to an hydraulic accumulator, the valve being operable to a position in which the accumulator is charged by the rotary starter which is then driven by the engine. The control valve is vacuum operated through an auxiliary valve whose inlet is connected to the engine induction manifold. As shown, a pump 2 is connected to the engine shaft. In order to start the engine the starting lever 9 is operated to release the piston 4. When the piston is released the auxiliary valve 13 is opened. The piston 4 impelled by the spring 6 exerts pressure on the oil in the righthand part of the cylinder 1. The oil is driven through the port 32 and passes to the inlet of the pump 2 which then acts as a hydraulic motor for starting the engine. As soon as the engine fires and gains speed a reduced pressure is transmitted from the induction manifold through the air valve 13 and draws the piston 16 against the action of the spring 17 and moves the control valve plunger 18 into its charging position in which the pump discharges to port 32. This forces the piston 4 to return against the pressure of the spring 6 until the pin 8 is locked by the hook 7. The starting lever is thus returned to a position in which the valve 13 is closed thus allowing the control valve plunger 18 to be returned to its starting and running position. The lever 9 has two positions determined by a toggle spring not shown). In the position of the parts shown oil is withdrawn from the port 32 and supplied to a control box 35 of an hydraulic drive system which controls forward movement of the platform of the truck in which the system is fitted. A low pressure part of the system is fed from a port 30. The accumulator may be recharged by means of a small mains, battery or hand operated portable or fixed pump. A small hydraulic motor (not shown) may be directly connected to a dynamo for supplying electrical accessories e.g. lighting equipment. The invention is particularly suitable for use with an hydraulic system for driving vehicle fork lift trucks for instance, as described in Specification 810,868 [Group XXIX]. An existing reservoir is simply replaced by the accumulator and the air operated control valve 13. The piston 4 may be loaded by gas pressure.

Title: Improvements in the manufacture of varnish resin interpolymers
IPC: C09D125/14
Filed: 1947-02-17
Abstract: A varnish resin is prepared by heating a mixture of (1) from 30 to 90 per cent by weight of a drying oil, free acid of a drying oil, or synthetic ester of a drying oil acid, which has a degree of conjugation not substantially exceeding that of dehydrated castor oil, and (2) from 70 to 10 per cent of a mixture of a polymerizable monovinyl aromatic compound and a nuclear alpha-methylene-lower alkyl aromatic compound, the alpha-methylene-lower alkyl group containing 3 or 4 carbon atoms and the mixture containing 50-80 per cent by weight of the monovinyl compound, to effect interpolymerization.  Suitable drying oils are dehydrated castor oil, linseed, soyabean, perilla and fish oils.  A mixture of one of these oils with a smaller proportion of a highly conjugated oil, e.g. tung oil, may be used.  The monovinyl aromatic compound is preferably styrene, but o- and p-methyl styrene, o- and p-ethyl styrene, o-p-dimethyl styrene, p-chlorostyrene, p-methoxy styrene and vinyl naphthalene may be employed.  Suitable alphamethylene-lower alkyl aromatic compounds are a -methyl styrene, p-methyl a -methyl styrene, a -ethyl styrene and p-chloro-a -methyl styrene. Polymerization may be effected by heating the mixture below boiling, e.g. 120-160 DEG  C., with or without a catalyst such as benzoyl peroxide, acetyl benzoyl peroxide, tertiary butyl perbenzoate and tert.-butyl hydroperoxide.  Alternatively, the drying oil is first heated to the polymerization temperature and the mixture of styrene or derivative and a -methyl styrene or derivative and catalyst is then added slowly over a period of several hours. Polymerization may also be effected in aqueous emulsion or in solution in, for example, diethyl benzene.  The viscosity and hardness of the resins may be increased by heating at a temperature above 250 DEG  C., but below their decomposition temperature, e.g. 275-295 DEG  C.  The resins are soluble in aromatic and aliphatic solvents and are compatible with linseed oil, most phenolic resins, some modified alkyd resins, rosin - esters, paracoumarone - indene, urea and melamine resins.  The examples describe varnishes comprising the resins dissolved in mineral spirits/xylene and mineral spirits/toluene mixtures, with cobalt and manganese naphthenate driers and in one case containing guaiacol to prevent skinning; and an enamel made by adding titanium dioxide.
