Title: Improvements in the manufacture and production of silicon fluorine compounds
IPC: C01B33/08
Filed: 1937-01-25
Abstract: Silicon fluorine compounds are obtained by reacting calcium fluoride, silicic acid and sulphuric acid, the sulphuric acid employed having a specific gravity of less than 1,5 at room temperature and the silicon-fluorine compounds being distilled off from the resulting reaction liquid as they are formed.  The process is preferably conducted at slightly reduced pressure and at 80-120 DEG  C., sulphuric acid of a specific gravity of 1,3-1,4 being used. According to an example, fluorspar containing calcium fluoride and silica is treated under slightly reduced pressure and at 110 DEG  C. in a lead-lined stirred container with mother liquor from a previous operation and sulphuric acid having a specific gravity of 1,4, the reaction being continued only until the specific gravity of the reaction mixture rises to 1,5.  Silicon tetrafluoride distils off and is collected in water for the formation of fluosilicic acid.  The remaining liquor is cooled and filtered, the gypsum residue being washed and the mother liquor being worked up with a new batch of reactants. Alternatively, the reactants, preferably after admixture with the mother liquor from the filtration of gypsum, are continuously introduced into the reaction vessel in which the specific gravity of the reaction mixture is maintained at about 1,45. At the same time the gypsum-containing reaction liquid continuously leaves the vessel through an ascending pipe in which the coarse non-converted particles of fluorspar separate from the finer particles of gypsum and flow back into the vessel.

Filed: 1925-01-27
Abstract: 250,700. Airship Guarantee Co., Ltd., and Teed, P. L. Jan. 27, 1926. Hydrogen.-In apparatus for generating hydrogen by the silicol process, sludge is removed intermittently or continuously in such a manner as to prevent the ingress of air to the generator. Thus, the sludge-discharge pipe B, Fig. 1, at the upper end of which is the sludge-valve b, is arranged to open into a tank C constituting a trap; the tank C is mounted on trunnions so that it may be tilted to the position shown in dotted lines, when the generator may be purged of air by admitting gas from the holder; a pipe D serves for the supply of water for flushing the valve b and the trap C. The generator may also be provided with means for relieving excess pressure, for example, to the outlet pipe E may be connected depending pipes D<1> the lower ends of which open below liquid in a suitably-shaped tank D. Alternatively the generating-chamber may be open at the bottom, the skirt dipping into a tank. To prevent the loss of solution due to steam being carried away by the gas, the latter may be passed through a condenser arranged in such a manner that the water condensed therein is returned to the generator; for instance, a tube condenser F, Fig. 5, may be mounted on the top of the generator A, the tubes f being arranged either horizontally as shown or vertically, in which case the cooling-liquid and gas may flow in counter current.

Title: Improvements in or relating to a machine and method for supplying a charge of propellant to an aerosol container and for thereafter sealing the latter
IPC: B65B31/00
Filed: 1956-01-25
Abstract: 784,922. Filling and closuring aerosol containers. PRECISION VALVE CORPORATION. Jan. 25, 1956 [May 4, 1955], No. 2465/56. Class 125(2). In filling an aerosol container having a valved closure, the mouth of the container carrying the closure loosely is sealed to a filling head, the closure is lifted clear of the mouth, propellant is supplied to the container, the closure is lowered to the container and then sealed thereon, and lastly the seal between the head and the container mouth is broken. Preferably the closure is of the type which is expanded into engagement with the mouth as disclosed in Specification 680,067 [Group XXIX]. As shown, the head comprises upper and lower cylinders 20, 21 fixed to an arm 6 carried at the top of a vertically slidable rod 8 reciprocated by a continuously-running motor 13 through a brakeclutch mechanism 15, gear box 10 and a crank 13. In operation, a container C is placed in a locating member 50 and actuates a switch 51 which causes a timer to be energized. The timer first actuates a control 52 which throws in clutch 15 and crank 13 moves through half a revolution to lower the arm 6, the clutch being then thrown out by a switch 18 actuated by a cam 16 driven from gear box 10. At this stage the shoulder of the container seals against a gasket 53 at the bottom of cylinder 21 and the closure X seals against a gasket 30 carried by a cylindrical flange 29 depending from the lower piston 28. The timer now opens a solenoid valve 54 in pipe 45 so that vacuum is applied above piston 28, this vacuum being communicated through a bore 55 to the upper side of the closure to hold it against the gasket 30. The timer then opens a solenoid valve 56 to admit pressurized air through pipe 46 below the piston 28 which is thus raised carrying the closure with it. The timer then opens twin valves 49 so that propellant flows into the container through pipes 48 which are tangential to the inner bore of block 27 to reduce foaming. After filling valves 49 close and vent valves 57 in pipes 45, 46 are opened so that a spring 44 lowers piston 28 and the closure is freed from the gasket and enters the container mouth. The timer then actuates a valve 42 so that pressure air passes through pipe 40 to the upper side of piston 37 in the upper cylinder 20. The piston descends and a plunger 39 depending therefrom expands fingers 35 so that the closure is expanded into the container mouth. When the piston 37 reaches its lowest point, it opens a switch 58 which reverses valve 42 so that pressure air flows through pipe 41 to raise the piston 37. The timer then actuates control 52 so that the crank 13 makes another half-turn to raise the arm 6 and then the clutch is thrown out by a cam 17 actuating switch 19. In a modified form the head may be fixed and the container support movable vertically.

Title: Method for simultaneously synthesizing methanol and liquid hydrocarbons
IPC: C07C29/151
Filed: 1926-01-28
Abstract: 247,932. Patart, G. Feb. 23, 1925, [Convention date]. Hydrocarbons; methyl alcohol.-A mixture of water gas with a gas from the distillation of coal when passed in equal parts bv volume over a catalyst adapted to form methyl alcohol from carbon monoxide and hydrogen, yields a product consisting of methyl alcohol and liquid hydrocarbons. The mixture of water gas and illuminating gas or coke oven gas in equal quantities is circulated at a pressure of 150-250 atmospheres over a zinc oxide-chromium oxide catalyst maintained at a temperature of 300‹ C. Pressures of 800-1000 atmospheres are also mentioned. The catalyst is prepared by reducing agglomeratea basic chromate of zinc. The portion of the gas entering into the reaction is periodically replaced by fresh gas mixture. The condensed product, when diluted with water, separates into two layers, the upper consisting of hydrocarbons derived from the ethylene content of the reaction gases and the lower of methanol mixed with water; the undiluted product may be used without further treatment as a fuel. The residual gas is allowed to expand in order to liquefy the methane, which may then be partially burnt with oxygen to produce a mixture of carbon monoxide and hydrogen for addition to the reaction mixture. The hydrogen still remaining in the non- liquefied residual gas may be separated by known means and also added to the reaction mixture. By these means the amount of water gas required for the initial mixture is reduced. Specifications 247,176 and 247,178 are referred to.
