Title: Improved Apparatus for Starting Rotary Internal Combustion Engines.
IPC: F02N15/00
Filed: 1918-04-26
Abstract: 115,834. Soc. des Magnetos R B. April 30, 1917; [Convention date]. Systems, electric.-For starting a revolving-cylinder engine, current is supplied by an auxiliary magneto or other source to two brushes b, c which are alternately in circuit with plugs in cylinders in which the piston is making a working stroke, a rotary switch f with a semicircular segment i and two brushes g, h short-circuiting the cylinder which is commencing its suction stroke. In its intermediate position, the segment i connects both brushes g, h during the period when the brushes b, c span the gaps between adjacent segments of the rotary distributor. The segment i is geared to rotate at n times the engine speed, n being the number of engine cylinders. According to the Specification as open to public inspection under Sect. 91 (3) (a) the speed of rotation of the segment i may be reduced by increasing the numbers of brushes g, h and diminishing the length of the segment. The brushes may be joined up to the primary of the starting-magneto instead of the secondary. This subject-matter does not appear in the Specification as accepted.
Patent GB-575865-A (GB)
Title: Abrasive articles and methods of making the same
Filed: 1944-04-18
Abstract: Abrasive articles such as grinding-wheels are made by precipitating a latex of copolymerized butadiene and styrene in the presence of granular abrasive material and a vulcanizing agent by means of a latex precipitating compound of an alkali metal and thereafter vulcanizing the mass in a desired shape.  The abrasive grains which may be alumina or silicon carbide are preferably ground to pass a 80-mesh inch screen and after dry mixing with ball clay and sulphur are added to the copolymer latex which is then precipitated by means of a 10 per cent aqueous solution of a precipitating agent such as caustic soda, sodium or potassium carbonate, sodium or potassium chloride, sodium acetate or crotonate.  The resulting paste is then moulded directly or is preferably spread on glass and dried at a temperature not exceeding 105 DEG  C. and the friable mass passed through a 60-mesh/inch screen.  Clay, cryolite or cured resin powders may be added to the particles which are then moulded with the optional addition of a binder such as phenol-, aniline- or resorcinol-formaldehyde, and methyl methacrylate resins, and plasticisers such as furfural, tricresylphosphate or triglycol dichloride; lime may also be added to take up residual moisture. Curing is effected at a temperature of 165 DEG  C. for several hours, the material preferably being held in a mould for 15 minutes under pressure and at a desired volume in order to control the porosity of the mass and then finished in an oven.

Title: Improvements in treatment of steam boiler water
IPC: C02F5/02
Filed: 1944-04-21
Abstract: A process of treating steam boiler water to prevent deposition of insoluble silica includes the steps of maintaining in the water in the boiler a ratio of potassium to sodium in equivalents of at p least .5, and maintaining additionally a ratio of silica to the captive alkalinity associated therewith plus the free alkalinity, in equivalents of not less than .75 and not more than 2.  Captive alkalinity is alkalinity which is removed with concentration of the boiler water.  The potassium may be supplied in place of sodium salts used in known processes of boiler water treatment, for example, in the form of carbonate, hydroxide, sulphite, sulphate or phosphate, as potassium silicate with or without potassium chloride or potassium borate, as a boiler compound containing potassium salts with or without organic material such as dispersive tannins, lignins or alginates, or as a coagulant in the form of potassium aluminate, potassium alum or potassium bentonite.  Feed water to the boiler may be treated by the base exchange process, the regeneration of the exchanger being a potassium instead of a sodium salt.  In another arrangement feed water is passed through two base exchange softeners, one regenerated by acid, and the other by a potassium salt, and the effluents are mixed together.  U.S.A. Specifications 1,613,656, 1,613,701 and 1,903,401 are referred to.

Abstract: 550,239. Speed governors. C. A. V., Ltd., and NICOLLS, W. E. W. June 27, 1941, No. 8113. [Class 135] A speed governing mechanism for prime movers and other machines comprises a main regulating element actuated by the fluid pressure in a circulating system Under the control of an auxiliary valve mounted in a radial bore in a rotor. The valve is urged outwards by centrifugal force against the fluid pressure in the conduit to control the inward radial flow of the fluid which fluid is discharged from the rotor through an axial passage. In the form shown in Fig. 1 fluid circulated by a pump h through a conduit # acts on a spring-loaded piston j coupled to the main regulating element. The rotor d driven at a variable speed correlated to' that of the machine under control has a radial bore m housing the piston valve o connected by circumferential grooves r and s and a passage t with an axial discharge passage n leading by way of a pipe c to the suction side of the pump. The valve o has an axial passage p connected by a pipe b with the pipe f and by radial passages q. with a peripheral groove. While the rotor is rotating the valve is held in equilibrium by centrifugal force and fluid pressure on the end face of the valve to hold -the grooves s, r more or less opposite one another so that the pressure in the pipe b varies with ' the speed of the rotor. In a modification a second radial passage controlled by a spring-loaded ball valve is provided. At high speeds the flow through the valve o is interrupted and the control is effected by the centrifugal force of the fluid in the second radial bore. Two or more bores and associated valves may be arranged in the rotor. In another form the valve co-operates with an annular seat surrounded by an annular chamber connected by a restricted aperture with the conduit b and by radial and transverse bores with the outlet passage n. This passage is fitted with a spring- loaded valve.
