Title: Improvements in or relating to methods and organosilicon compositions for rendering masonry water-repellent
IPC: C04B41/49
Filed: 1952-05-12
Abstract: A liquid organosilicon polymeric composition, for rendering masonry water-repellent, is made by (1) separating a mixture of the high boiling distillable by-products from the reaction of CH3Cl and Si to produce methylchlorosilanes, the components of the mixture having a boiling point above that of (CH3)2SiCl2, (2) alkoxylating the by-products with one or more primary or secondary lower alkyl monohydric alcohols in amount equivalent to at least 30 molar per cent. of the hydrolyzable chlorine in the mixture; and (3) partially hydrolyzing the alkoxylated product with water in amount such that the final product contains from 20 to 50 per cent. by weight of alkoxy groups.  The preferred alcohols contain 1 to 4 carbon atoms. The compositions may be dissolved in solvents such as benzene, toluene, xylene, cyclohexanone, kerosene, naphtha, stoddard solvent, mineral spirit, ethers, ethanol, butanol, acetone, carbontetrachloride, and butyl acetate.  The resinous reaction products of silica-hydrogels with (CH3)3SiX, where X is chlorine or alkoxy, or [CH3)3Si]2O (see Specification 706,719) may be added in amounts up to 100 per cent. by weight of the hydrolyzate.  The compositions may be used in conjunction with conventional organic materials used in treating masonry, e.g. aluminium stearate, paraffin and a drying oil, oleoresins in vegetable oil vehicles such as linseed oil. and emulsions of resins, usually with plasticizers, such as polyvinyl acetate and polystyrene.  Examples are given. Specifications 575,667 and 609,507, [Group IV (b)], also are referred to.

Title: Improvements in the production of kinematograph film positives
IPC: G03B33/00
Filed: 1928-04-25
Abstract: 316,338. Thornton, J. E. April 25, 1928. Kinematograph picture films; colour - - photography.-An unperforated blank film which is dye-receptive on both sides is simultaneously printed on opposite sides by photo-mechanical or imbibition processes to produce two full-tone pictures in accurate register, the doubly-printed film being perforated subsequently to printing. The pictures may be printed from two printing-belts such as may be produced by the process of Specification 5,100/15, these belts being maintained in accurate register, as by oppositely-disposed sprocket rollers, each having alternate feed pins and recesses. If intaglio surfaces are used for printing, the colour or dye is thickened with a glutinous filler to keep it from running out of the hollows. Apparatus for printing the blank film and subsequently perforating it is described in Specification 316,388. Alternatively the subsequent perforating may be done by the method and apparatus of Specification 12230/12, [Class 31 (ii), Punching and perforating machines &c.], which involves visual control during the perforating. The blank film may be cast from dope made from a mixture of gelatin and cellulose acetate, or of gelatin and nitrocellulose, using a solvent common to both components. The printing dye is chosen to suit the composition of the blank, the surface of which may contain mordanting agents. Alternatively ordinary film stock may be faced on both sides with dye receptive coatings. Additional printings may be superimposed on the two-colour. printed blank for obtaining three or four colour films, a thin layer of absorbent colloid preferably being applied between the superimposed printings. For' monochrome pictures two images can be used, one being used to intensify the other only in parts, or two identical images printed in different colours producing black when superposed. Instead of the two different images a general tint or colour may be applied on one side to tint the other monochrome image. Specifications 9324/12 and 231,030 also are referred to.

Title: Improvements in and connected with the coating of metal surfaces with vitreous coatings of enamel, glaze, glass or the like
IPC: C23D5/04
Filed: 1924-05-20
Abstract: 243,033. Lambert, W., Mead, A. A,., and Stone & Co., Ltd., J. May 20, 1924. Drawings to Specification. Vitreous enamelling.-A hot enamelling or glazing process for coating metal objects while they retain sufficient heat from a previous treatment to effect complete vitrefaction of the enamel comprises the delivery of a reducing or neutral agent to the metal simultaneously with the coating-material to prevent the formation of oxide and to reduce any oxide previously formed on the surface. The invention is applicable especially for applying coatings of enamel, glass, glaze, or the like to the interiors of hollow members such as tubes while they are still hot and spinning from a centrifugal casting process. In such cases the enamel is introduced into the pipe in company with a reducing agent which may either be a. constituent of the enamel or a neutral or reducing gas or liquid introduced into the vicinity of the treated surface. Various methods of introducing the enamel into the tube are illustrated in the Specification. In one form a tube, with one end cut away to form a semi-circular gutter, is introduced into the spinning tube and rotated through 180‹ to tip the enamel out. In another form, the gutter holds enamel powder and is furnished with slits through which the powder escapes when the tube is shaken by a pneumatic hammer device. In a third form, an axially movable non-rotating tube delivers the enamel powder through a centrifugal nozzle at one end. In another form, an axially moving spraying-nozzle is connected to a container of liquid enamel and also to a chamber of reducing gas under pressure. Where the enamel is applied in liquid form it can be preheated to a certain extent to assist in the application. The gaseous propellant may comprise a combustible gas, products of combustion, or a combined combustible and reducing-gas such as carbon monoxide.

Filed: 1967-03-17
Abstract: 1,148,016. Plates from wood chips &c. DEUTSCHE NOVOPAN & CO. G.m.b.H. 17 March, 1967 [17 March, 1966], No. 12526/67. Heading B5A. [Also in Division C3] Plates or moulded bodies are made by extrusion or hot-pressing of a mass of wood chips, wood fibres or lignified raw materials mixed with binding agents which include an isocyanate solution. The isocyanate is preferably a solution of diphenylmethane 4,41-diisocyanate, toluene 2,4-diisocyanate or naphthalene 1,5-diisocyanate and is used in 2-20% by weight relative to the dry ligneous material, the isocyanate being applied either mixed with or after the urea-formaldehyde, melamineformaldehyde or phenol-formaldehyde resin preferably used as the binding agent. A compound with free OH groups, e.g. glycerine, pinacone, ethylene glycol, polyethers or polyesters may be sprayed or spread on to the surface to prevent the moulded mass from sticking to the mould; the boiling-points of the compounds being higher than or not considerably lower than the pressing temperature. Animal and fungi resistance may also be increased by the addition of alkali metal fluorides and bifluoride, boron compounds, chromium or copper in powder form or pentachlorophenol to the shavings before processing. The pentachlorophenol combines with the isocyanate and is not removed during presssing. The impregnation process may be carried out by adding the resin binder to the wood, mixing for 5-60 minutes at 20‹ C. or for a shorter period at 50-90‹ C. under, for example, an eddy current dryer which removes water, the temperature being insufficient to cure the resin, and then treating with isocyanate and pressing.
