Methods for manufacturing carbon and/or graphite materials

Abstract: CARBON AND/OR GRAPHITE MATERIALS HAVING HIGH DENSITY AND MECHANICAL STRENGTH ARE PREPARED BY IMPREGNATION OF A SOLID CARBONACEOUS MATERIAL WITH A SOLUTION OF A CHEMICALLY ACTIVE COMPOUND WHICH IS AN INORGANIC COMPOUND CONTAINING NICKEL, MANGANESE, BARIUM, SULFUR OR NO3, NO2, CLO3 OR CLO4 GROUPS OR AN ORGANIC COMPOUND CONTAINING NITRO, PHENOL, PEROXIDE OR ACID GROUPS, FOLLOWED BY IMPREGNATION WITH A FLUID CARBONACEOUS MATERIAL, E.G. COAL TAR PITCH, AND HEAT TREATMENT.

Method of altering the surface properties of polymer material

Abstract: 1,149,052. Silicon oxide or nitride coatings. STANDARD TELEPHONES &.CABLES Ltd. 28 Oct., 1966 [2 Nov., 1965], No. 46289/65. Heading C1A. [Also in Divisions B2, C7, D1 and H5] In a method of altering the surface properties of a sheet, film, fibre, yarn or woven fabric of a polymer material (e.g. of polyethylene, polypropylene or silicone), (a) the surface is provided with a surface modifying layer consisting of an element or an inorganic compound (e.g. Si, silica or silicon nitride), (b) the energy necessary to promote the required chemical action for the formation of the layer is provided by establishing by capacitive means an alternating electrostatic field adjacent to the surface in a gaseous atmosphere at a pressure below atmospheric pressure, and (c) when the layer consists of an element, the gaseous atmosphere contains the element as an inorganic compound and, when the layer consists of an inorganic compound, the gaseous atmosphere contains all the elements of the inorganic compound as substances other than the inorganic compound with at least one of the inorganic compound elements being present in the atmosphere as a compound. The Figure of the Provisional Specification illustrates the application of a surface modifying layer to a fibre 5 of polymer material as it passes through a quartz tube 1 which contains a gaseous atmosphere at a pressure of 0A1 to 1A0 torr. An alternating electrostatic field is produced by an R.F. power source 3 connected to a metal mesh 2 surrounding the tube 1 and to metal end caps 4 to the tube. In depositing the following materials, the atmospheres are as indicated: (a) Si-silane. (b) Silica-silane and N 2 O, CO 2 , H 2 O vapour or O 2 . (c) Silicon nitride-silane and NH 3 . The Specification refers to matter claimed in Specification 1,104,935.

A new method of preparing inorganic compound foil by sublimation of substrate

Abstract: A new method is described for the preparation of a foil of an inorganic compound, without substrate, in the vacuum of an electron optical apparatus. The method is applicable to deliquescent materials.
