Title: Process for making dispersions of solids in liquids
Inventor: ARMSTRONG JAMES E
IPC: B05B7/14
Filed: 1957-04-25
Abstract: A clear homogeneous silica hydrosol is produced by mixing a solution of an alkali metal silicate with an inorganic acid which comprises introducing into a mixing zone a stream of alkali metal silicate solution at a pressure and direction sufficient to create a whirling mass thereof, passing the whirling solution downwardly through a confined area in said zone to a mixing chamber having a restricted discharge port and introducing a finely divided stream of mineral acid into said chamber in a hollow conical pattern in contact with the whirling silicate solution said acid stream having an apparent pressure of at least 125 psia, thereby creating extreme turbulence within the mixing and resulting in an apparent pressure of at least 250 psia and collecting the resulting silica hydrosol.  The sol contains 10-20% by weight of silica and the acid is introduced in amount slightly in excess of that necessary to neutralise silicate. The hydrosol can be discharged from the mixing zone under the surface of a bath of previously formed hydrosol.  Specification 627,500 is referred to and the process may be used using the mixing nozzle described and claimed in Specification 844,950.

Patent GB-716920-A (GB)
Title: A process for the mass production and treatment of pathogenic viruses and substances which accompany them
IPC: C12N7/00
Filed: 1952-05-28
Abstract: In the propagation of viruses, e.g. of foot-and-mouth disease, animal tissue in which the virus propagates selectively is fragmented and diluted, suitably with amniotic liquid, to form a suspension, and as such, introduced into the body of an animal susceptible to the virus, e.g. under the skin or into the abdominal or pleural cavity, wherein it is permitted to develop into a neoformation mass of substantial size, whereupon the virus is introduced into the animal, if desired, directly into the neoformation mass, and allowed to propagate until the neoformation mass becomes virulent, the latter is then removed, fragmented, undesired tissues being removed if desired, and ground until the cells are destroyed, preferably at low temperature.  The selected tissues may be obtained from a foetus or adult animal; in the latter case, they should be treated with antiseptics or antibiotics.  The virus may be modified by mixing it, prior to inoculation, with polysaccharides, viz. hyaluronic acid and its sulphuric esters such as chondroitine sulphate and mucoitine sulphate.  These substances may alternatively be introduced into the embryone.  The ground virulent tissue is mixed with the virulent liquids produced, filtered or centrifuged, and the desoxyribonucleoprotein fraction may be extracted by the action of concentrated sodium chloride; the ribonucleo-protein fraction can be extracted by acidification.  All the nucleo-proteins may be precipitated with lanthanum choride.  The globulin fraction may be precipitated by the addition of 50 per cent ethyl alcohol.  All the proteins may be precipitated by dioxane or a mixture of alcohol and dioxane.  Precipitation may also be effected by acetone or ammonium sulphate.  The various fractions or the total residue may be dried in vacuo at low temperature or they may be absorbed on alumina gel. Filtered saliva of cattle and/or milk, alone or in association with glycerine, may be added to the virulent material before the solids are separated or proteins precipitated.  The saliva is first treated with antiseptics, e.g. tricresol, phenol, formol, thymol, toluene, or sulphonamides or antibiotics, or it may be otherwise sterilized.  The virulent matter, at various stages of its treatment, may be attenuated by the action of physical agents, e.g. temperature, ultra violet radiation, or by e.g. formaldehyde, or other agents such as d-glycuronic acid, d-glucurone, glucosamine, N-acetyl-d-glucosamine, glucosamine hydrochloride, galacturonic acid, or by tricresol, the isomeric cresols, quaternary ammonium derivatives, derivatives of p-hydroxybenzoic acid or of p-chlorobenzoic acid, hydroxyquinolinic acid, phenol, thymol or toluene.  The virulent matter, mixed if desired with milk and/or saliva, and attenuated as indicated, may be preserved in the liquid state, or dried in vacuo.  The dry material may be kept in sealed tubes in vacuo or in an atmosphere of nitrogen.

Abstract: 293,530. Royce, F. H. May 21, 1927. Fluid-friction vibration-dampers in which the flow of pressure fluid is controlled by a spring- loaded valve with an adjustable spring abutment, are provided with means for adjusting the seat consisting of a cylinder supplied with liquid from a continuously working pump, the delivery of which is regulated by a speed governor or by hand. Fig. 1 shows a vertical section through the vibration damper and Fig. 2 a vertical section on the line 2-2, Fig. 1. The double ended piston b is reciprocated from a spindle b<3>, the two ends of the cylinder being connected, in order to make up for leakage, by one way valves d<3> to a central oil reservoir a<10> communicating with the upper chamber a<8>. When the piston moves to the right, liquid passes through the port d' and upwards past the valve c2 to the chamber C from which it is conveyed through passages d<6>, d<5> and d<4> to the left end of the cylinder. Movement of the piston to the left discharges liquid through the passages d<4> and d<5> to the underside of the other valve c<22> from which it passes upwards to the space c' and returns through the port d<8 >to the right end of the cylinder. The pressure exerted on both of the valves c<2>, c<22> is regulated simultaneously by movable abutments c<6>, c<66> for the upper ends of the closing springs c<3>, c<33>. The stems of the abutments are forced downwards by fluid pressure on the upper side of a diaphragm f, having circumferential corrugations and pressing through a central stem e<4> on a lever secured to a spindle e<2> also carrying other levers engaging the ends of the abutment stems. The pressure on the upper side of the diaphragm is maintained and varied by the apparatus shown in Figs. 6 and 7 through a pipe i<4> which is shown connected to two of the vibration dampers described above. A continuously rotating pump i draws liquid from the reservoir i and discharges it into the passage i<3> connected to the vibration dampers and through the spring loaded valve k<1> back into the reservoir. The pressure on the upper end of the spring k<3> and hence the pressure, in the pipe i<4> is regulated by a rod k<6> connected by linkwork to a speed governor or to a hand control.

Title: Improved processes for the preparation of sulphur halogen compounds
Inventor: ROBERTS HUGH LEITHEAD
IPC: C01B17/45
Filed: 1958-04-30
Abstract: Polytetrafluoroethylene is produced by irradiating sulphur pentafluoride monochloride (see Group III) with ultra-violet light in the presence of tetrafluoroethylene.  The -SF5 free radicals produced induce polymerization.  It is indicated that these radicals can be formed by other forms of light and can catalyse any polymerization reaction catalysed by free radicals.ALSO:Sulphur pentafluoride monochloride is prepared by reacting fluorine with SCl2 or S2Cl2 at low temperature. Electrolytic F2 is passed over NaF to remove HF and through a copper spiral immersed in liquid air to remove moisture. The F2 is mixed with a dry mixture of N2 and SCl2 and passed to a copper reaction vessel.  For a wholly gas phase reaction the vessel is at 0 DEG  to -20 DEG C., and for a gas/liquid phase reaction the vessel is at -20 DEG  to -80 DEG C.  The mixture of Cl2, SF4, SF6, and SF5Cl produced may be treated with BF3 to remove BF3.SF4, acidified FeSO4 solution to remove Cl2, and the SF5Cl and SF6 are separated, after drying, by gas-chromatography using a column of polychlorofluorocarbon (CF2CFCl)n. SF4 may be recovered from the BF3.SF4 by subliming at 80 DEG C. over NaF to form sodium fluoborate and SF4 which is condensed at -40 DEG C.  If the SF4 is not required, the product mixture is passed through acidified FeSO4 solution, acidified potassium dichromate to remove SO2 produced during hydrolysis of SF4 in the first solution, and SF5Cl and SF6 are separated after drying as before.  Irradiation of SF5Cl with U.V. light in the presence of tetrafluoroethylene yields polytetrafluoroethylene, or copolymers of polytetrafluoroethylene and SF4.
