Title: Improvements in and relating to the manufacturing of abrasive articles
IPC: B24D3/28
Filed: 1939-01-27
Abstract: 528,563. Moulding abrasive articles. NORTON GRINDING WHEEL CO., Ltd. Jan. 27, 1939, No. 2917. Convention date, Jan. 28, 1938. [Class 87 (ii)] [Also in Group IV] Abrasive articles are prepared by introducing into a mould abrasive grain and a liquid polymerizable resin-forming mixture consisting of a monohydric alcohol or phenyl ester of methacrylic acid in admixture with one or more of the following substances : methacrylic acid, allyl methacrylate, and a polyhydric alcohol ester of methacrylic acid having two methacrylic radicles per molecule, and heating to polymerize and set the resin. The monomeric mixture may be partly polymerized or have polymers dissolved therein before use. The mixture may be poured upon abrasive grain in the mould, sufficient mixture being added to provide clear liquid above the grain, the surplus resin which does not contain abrasive being afterwards removed. In making grinding wheels, a mould having a cylindrical side wall and a central plug may be employed, the wall of plug being slightly tapered to facilitate removal of the wheel. In examples, grinding wheels are prepared by abrasive grain, e.g., alumina, corundum, emery, diamonds, garnet, quartz, or silicon, tungsten, tantalum or boron carbide, in the mould, adding a mixture of methyl methacrylate, benzoyl peroxide and (1) ethylene glycol dimethacrylate, (2) glycerol trimethacrylate, (3) pentaglycerol trimethacrylate, (4) methacrylic acid, (5) methacrylic acid and ethylene glycol dimethacrylate, (6) allyl methyacrylate, or (7) allyl methacylate and ethylene glycol dimethacrylate, and heating to effect polymerization of the mixture. In example (8), the resin-forming mixture comprises partly polymerized methyl methacrylate and monomeric methacrylic acid. The methyl methacrylate may be replaced by the isopropyl, isobutyl, or the phenyl ester of methacrylic acid. Specifications 528,962, [Group IV], 2916/39, 2918/39, 2919/39, and 2920/39, all as open to inspection under Sect. 91 are referred to. According to the Specification as open to inspection under Sect. 91 the bond for the abrasive is a solid resin derived from any polymerizable liquid. This subject-matter does appear in the Specification as accepted.

Title: Bonded synthetic organic polymeric and glass fibres
Inventor: RAWE ALAN WILLIAM
IPC: D04H3/12
Filed: 1960-01-27
Abstract: Synthetic organic polymeric fibres, e.g. nylon, polyethylene terephthalate and polyethylene fibres, and glass fibres are curled by passing them through a bath of an elastomer or an organic binder, i.e. a thermoplastic or thermo setting resin, to coat or impregnate them and then winding them on to a rotating cylinder which is traversed by the fibres in one longitudinal direction, the elastomer or organic binder being cured during or after traversing the cylinder.  The elastomer may be a natural or synthetic rubber, e.g. a silicone rubber, and the organic binder may be a phenolic, epoxide or ureaformaldehyde resin or polyethylene, nylon or polyvinyl chloride. The stiffness of fibres treated with silicone rubbers may be modified by incorporating varying amounts of diatomaceous earth fillers in the silicone rubber bath.  The helically curled fibres are subsequently bonded together with an elastomer to form, for example, a pack suitable for use as energy absorbing or insulating material.

Title: Tin (ii) chlorofluoride and tin (ii) monochlorotrifluoride
IPC: A61Q11/00
Filed: 1956-02-02
Abstract: Stannous monochlortrifluoride (Sn2ClF3) is made by treating a solution of stannous chloride with hydrofluoric acid and crystallizing the solution, in which the solution contains not less than 50 per cent of water by weight and the stannous chloride and hydrofluoric acid are less than 50 per cent by weight. Preferably the water used is oxygen-free, and cooling the warm solution to crystallize at room temperature is effected under an inert atmosphere, e.g. nitrogen or hydrogen.  The tin chloride may be used in anhydrous or hydrated form.  In an example 74 g. Sn Cl2.2H2O are dissolved in 50 g. water at 60 DEG  C. and 13.7 g. of a 48.5 per cent solution of HF is added and mixture allowed to cool.  With lower proportions of water stannous chloro fluoride (SnClF) is also produced in admixture with the monochlor trifluoride.  These compounds may be used to prepare dentifrices (Group VI).ALSO:Dentifrices reducing the formation of caries, contain stannous monochlortrifluoride (Sn2ClF3), stannous chlor fluoride (SnClF) or a mixture thereof (see Group III).  In examples, up to 0.58 per cent by weight of stannous mono chlor trifluoride is mixed with sodium carboxy methyl cellulose; magnesium aluminium silicate, alumina, calcium carbonate or dicalcium phosphate; sodium coconut monoglyceride sulphonate; lauryl alcohol sulphate; water, colour, and a humectant, e.g. spearmint, wintergreen and sweetening agents. Alkyl sulphoacetates, sarcosides and soaps may also be present. Liquid dentifrices may be dispensed from a pressurized container.

Abstract: 1,070,351. Electro erosion. SPARCATRON Ltd. April 27, 1966 [Jan. 27, 1965], No. 3595/65. Heading B3V. [Also in Division F1] An hydraulic or compressed gas-operated piston (2) Fig. 1 (not shown), for use in a servo feed mechanism of an electro-erosion apparatus, having small and large diameter rods (1, 1a) extending through chambers (17, 16) at opposite ends of an associated cylinder (3), occupies less than the full bore of the cylinder and thus allows flow of pressure fluid from a pumpsupplied inlet (15) at the large diameter rod end of the cylinder, past the piston and through a throttle valve-controlled outlet (18) at the small diameter rod end of the cylinder. In operation and assuming effective piston area A<SP>11</SP> in chamber (17) to be twice area A<SP>1</SP> in chamber (16) and that areas of piston gap and throttle valve (19) to be F<SP>1</SP>, F<SP>11</SP> respectively, then piston 2 is in equilibrium when p<SP>11</SP>= 0À5P<SP>1</SP> which occurs when F<SP>11</SP>=F<SP>1</SP>. On restricting valve (19) by varying amounts P<SP>11</SP> rises by varying amounts resulting in downward displacement of piston (3) and varying thrusts being exerted by a tool (9) carried by rod (1a) and bearing on a workpiece (10), Similarly, on opening valve (19), upward thrusts of variable magnitude are exerted by the piston which is locked in its raised position by its rod (1a) being held by a pressure switchoperated clamp (28). The piston may have a peripheral annular groove or a single helical groove and the cylinder wall may have a helical groove of the opposite hand. The tool (9) may be an electrode for cutting material by electro erosion or it may be associated with an ultra-sonic vibration generator (6) for cutting or working materials. The valve (9) is electromagnetically controlled either to maintain a specified gap between an electrode and the workpiece, in which case the valve is responsive to an error signal derived from one or several parameters of the electro-erosion circuit, or the valve (9) is controlled so as to maintain the required thrust during an ultrasonic cutting operation and is responsive to the thrust exerted.

[Class 7 (iii).] The mixing chamber is divided by a tapering conduit 13 into two compartments which are in constant communication with one another through ports 15 and to each of which fuel is supplied through a spraying nozzle 7. Orifices 17, 16 in the nozzle supply auxiliary fuel and fuel for slow running. With the throttle valve 11 closed a slow running mixture is drawn through passages 9, 10, and as the throttle opens the orifice 17 is brought into action ; during normal running fuel issues through the orifice 17 and the nozzle and if the throttle opening is increased air enters the mouth of the nozzle 7 to decrease the fuel supplied through the orifice 17. A needle valve may control the outlet of the nozzle 7. When starting, the carburetter may be supplied with light fuel whilst during normal running heavy fuel may be used. The drawings of the Specification as open to inspection under Sect. 91 (3) (a) show a modification in which a throttle valve is mounted in the tapering conduit. This drawing does not appear in the Specification as accepted.
