Title: Improvements in driving gear for turntables or other rotary members
IPC: C02F3/04
Filed: 1946-07-16
Abstract: 628,563. Roundabouts. HITCHINS, C. B. July 16, 1946, No. 21210. [Class 132 (i)] [Also in Groups XXVI and XXIX] A gravity-operated uni-directional driving gear of the swash-plate type comprises a driving shaft which is inclined to a vertical axis and moves bodily, without rotating on its own axis, to trace out the surface of a cone. The lower end of the shaft moves in a circle in a horizontal plane and is coupled to a  driven member to rotate it about the vertical axis. The driving shaft carries a platform, to the plane of which it is perpendicularly arranged. The platform is provided with elements for receiving driving material or a driving body and is adapted for discharge of the material or removal of the body when these elements are at their lowest point of travel. The driving gear is described as embodied in a rotary sewage distributor, but it may be applied to driving a merrygo-round, the operator constituting the driving body. A rotary sewage distributer consists of a rotary collecting vessel 15 to which are attached two radial arms 20 having a number of horizontally arranged discharge openings 21. Each arm 20 is provided with a longitudinally extended lip 25 having a serrated edge 26 to facilitate distribution of the sewage and is supported from the collecting vessel 15 by bracing rods 22. Located eccentrically in the base of the vessel 15 is a cup bearing 27 supporting the lower end 28 of the driving shaft which is arranged in an inclined position with its upper end 29 provided with an axial slot 30 in which is engaged a fixed horizontal pin 31. The slot extends both above and below the pin so that the driving shaft is free to pivot not only about the axis of the pin but also about an axis at right angles thereto. The driving shaft may therefore be moved so as to trace out the surface of a cone but is prevented by the pin 31 from rotating on its own longitudinal axis. The pin 31 is attached to a bracket 32 secured to the fixed sewage supply channel 33. Fixed on the driving shaft is a disc 37 provided on its upper surface with vanes 38 having a radial portion 39 and a circumferential portion 40 to form a number of angularly spaced pockets.. Liquid from the channel 33 is fed through a port 34 to a rotating distributing chute 35 from which it passes through an opening 36 on to the disc 37 to effect rotation of the vessel 15. As the chute 35 rotates with the vessel 15 the position of the opening 36 is fixed relative to the bearing 27 so that the liquid always enters the highest part of the disc 37 and thus causes the vessel 15 to be driven continuously. The vessel 15 may be provided with a cover.

Abstract: 441,404. Vacuum engines. LUCAS, Ltd., J., Great King Street, Birmingham.-(Bijur Lubricating Corporation; 22, 43rd Avenue, Long Island City, New York, U.S.A.) July 20, 1934, No. 21312. [Class 122 (iii)] [See also Groups XXVIII and XXXIV] In a lubricating-pump for an automobile chassis, operated by variations in the vacuum in the intake manifold, a baffle is inserted in the pipe between the pump and the manifold. The pump plunger 20, Fig. 2, is connected to the rod 22 of a diaphragm 23 in a chamber 24. The lower part of the chamber is connected to atmosphere, while the upper part is connected to the intake manifold by a pipe C, in which a baffle unit 25 is inserted.

Abstract: 294,490. Soc. d'Etude des Verres et Glaces de S³retÚ, (Assignees of Duclaux, J.). July 21, 1927, [Convention date]. Cutting glass.-Relates to a method of cutting reinforced glass formed of two sheets of glass united by a sheet of transparent material, usually celluloid or a cellulose compound. According to the invention, a scratch is made with a, cutting- tool on both faces of the glass. the scratches being of sufficient depth to reach the inner layer. The glass is then immersed in a. liquid having the property of softening or dissolving the material of the inner layer. The liquid penetrates the scratches, and after a suitable time, both parts of the compound sheet can be separated. When the unwanted part of the sheet has been removed, the exposed edges of the glass are coated with a substance having a defined melting-point above 70‹ C., such as sulphur, naphthalene., or colophony. Other suitable coating-materials are siccative mixtures, a mineral cement, organiccompounds of silicon, or a fusible metallic alloy preferably containing bismuth.

Patent GB-643169-A (GB)
Title: Improvements in the manufacture of co-polymers
IPC: C08F214/06
Filed: 1947-08-06
Abstract: Vinyl chloride is copolymerized with acrylonitrile starting with amounts of monomer in a ratio between 8 : 1 and 40 : 1, the process being carried out without addition of acrylonitrile or removal of unreacted vinyl chloride, and being stopped before the formation of any acetone insoluble copolymer.  The process may be carried out in emulsion, suspension or solution and the components may be fed to a tube at such a rate that the required conversion, e.g. 15-20 per cent, is obtained at the egress.  Vessels connected in cascade may be used.  Sodium octadecyl sulphate, alkali metal soaps, bentonite, methyl cellulose, polyvinyl alcohol, ammonium or alkali metal persulphates, perborates and percarbonates, hydrogen peroxide, benzoyl, acetyl, acetyl-benzoyl, lauryl and alkyl peroxides, diazo amino benzene, benzene diazo hydroxide, benzene diazo acetate, benzene diazo triphenyl methane, nitrosoacetanilide, tetraphenyl succino-nitrile, tetrachlorophenyl succino-nitrile, silver nitrate, copper sulphate, alkali metal ferricyanides, and cobalticyanides, formaldehyde, acetaldehyde, carbon tetrachloride, dioxanes, dodecyl mercaptan and tetraalkyl thiuram sulphides and disulphides may be added.  The vinyl chloride monomer may be evaporated off and the acrylonitrile dissolved by a hydrophilic solvent.  The copolymer latex may then be broken by freezing, adding electrolytes or atomizing into heated air or alcohol.  By adding a reducing agent or inhibitor the reaction may be stopped at the required conversion. The product may be stabilized by adding lead carbonate, naphthenate, laurate, or stearate, adipic dihydrazide, oxalic dihydrazide, or phenyl acetamidine, and used in melt spinning fibres, coatings, foils and mouldings.

Title: Preparation of salcicylic acid and its alkali metal salts
IPC: C07C51/15
Filed: 1961-06-14
Abstract: Salicylic acid and its alkali metal salts are prepared by the carboxylation of an alkali metal phenate in the presence of a substantial proportion of phenol wherein the carboxylation reaction is carried out at a temperature in the range of 140 DEG  to 175 DEG C. under a pressure of 2 to 36 atmospheres absolute using an anhydrous phenolphenate solution which is vigorously stirred to provide fresh solution surfaces for the carbon dioxide absorption and combination with the phenate. The process is preferably continuous, the unreacted phenol-phenate solution being recycled. The product is recovered by sedimentation and filtration and is preferably washed with solvents such as toluene, xylene or chlorobenzenes the filtrate being used to dry the phenol-phenate starting material by azeotropic distillation. In an example a mixture of 1 mole of sodium phenate and 3.5 moles of phenol is dried by azeotropic distillation and carbonated at 165 DEG C. under 5 atmospheres pressure for 1 hour with stirring to give sodium salicylate.
