Title: Improvements in or relating to organosilicon waterproofing compositions
IPC: C04B41/49
Filed: 1957-08-22
Abstract: A composition for waterproofing masonry consists essentially of a water-soluble siliconate dissolved in a water phase which also contains a dispersion or emulsion of rubber latex.  The siliconate may be an alkali metal or ammonium salt of a silanol, e.g. R2Si(OH)2 or RSi(OH)3, o the corresponding siloxanol, in which each R is an alkyl, alkenyl, alicyclic, aryl, alkaryl or halogenated hydrocarbon radical.  The latex may be one of a natural, prevulcanized or synthetic rubber.  The compositions may be (a) applied to the surface of a wall or floor where it is desired to prevent penetration of liquid water and watervapour, (b) injected into masonry through a series of holes to form an effective damp-proof course at the sites of injection, or (c) incorporated in cement mixes suitable for rendering on damp walls or below ground level or on damp flooring. In Examples (1) a composition for injection into holes drilled in a mortar layer consists of 8 pts. (by wt.) of an aqueous solution of the mono-sodium salt of methyl silane triol (40% solids), 80 pts. of water and 12 pts. of a natural latex (60% solids) ; (2) a composition for surface application as a paint consists of 10 pts. of the siliconate of (1), 75 pts. of water, 10 pts. of a prevulcanized latex and 5 pts. of aluminous cement ; and (3) a composition for application as a screed or rendering to damp walls or floors or to roofs, consists of 5 pts. of the siliconate of (1), 30 pts. of water, 15 pts. of latex, 15 pts. of aluminous cement and 35 pts. of washed sand.  Hardeners or hardening accelerators for the cement may be added to the compositions as used in (3).

Reductive surface treatment may be combined with other stabilizing treatments by reacting the CrO 2  with e.g. nickel tetracarbonyl or m-trifluoromethylphenyl copper, which form protective phases containing nickel and copper respectively. Before reduction, the CrO 2  starting material, which may have a saturation of at least 75 emu/g. and a coercive force of 200 -600 oersteds, may be heated in an oxidizing environment at 150-450‹ C. and a pressure of 0À2-3000 ats.

Abstract: 860,502. Coating by vapour deposition. CORNING GLASS WORKS. Aug. 27, 1958 [Sept. 4, 1957], No. 27532/58. Class 82(2) [Also in Groups XI and XX] In a method of producing a colour filter, vapours of a pure material selected from the class consisting of cadmium sulphide, cadmium selenide and mixtures thereof (e.g. cadmium sulphoselenide) a r e thermally evaporated on to the surface of a transparent, clean glass base to form a film preferably of not more than one micron in thickness. As shown, the base 20 to be coated is mounted in a vacuum chamber 10, having a crucible 18 containing the coating material, and electrically heated by current passing through coils 24 to a temperature not more than 800C. The pressure in the chamber is preferably reduced to below one micron of mercury. To ensure removal of any impurity in the coating material the crucible temperature is first maintained for a time at slightly below the melting point. And it is preferred that the condensation should be effected in two stages, in the interval between which the coated glass is baked in an oven at a temperature of about 500C. in order to improve the film adherence. When a cadmium sulphide film is being formed, the glass base is preferably maintained at a temperature of about 350C. during coating by a heating coil adjacent thereto, to prevent slight decomposition of the material. Alternatively, a slight departure from the required colour characteristics, due to such decomposition, may be corrected by subsequently heating the coated article to a temperature of 350C. -500C. Before introduction into the chamber 10, the glass surface 20 is cleaned as by washing in a dilute nitric acid solution, followed by distilled water and drying. Four specific examples of the method are given
