    摘要： A coating composition comprises an aqueous solution of lithium sodium silicate (see Division C1), 2-4 parts of a metallic dust, e.g. Zn of particle size 3-25 microns, and an alkali metal dichromate, e.g. 0.05-10%, optionally together with sand or silica gel, other finely divided metals, e.g. Al or Mg, metal oxides, e.g. Mn, Fe, or Ti, and 0.01-20% alkali metal or ammonium borate or bicarbonate. The Li-Na silicate solution, either alone, or with the addition of 5-80% of a filler, e.g. casein, clay, sugars, aluminiates, or asbestos, and 0.01-3% of a curing agent, e.g. KCl, KBr, or borax, may be used as an adhesive or cement for wood, paper (Example 11), cardboard (Example 10), plastics, glass (Example 7), metals, concrete, or brick. Specification 1,007,482 is referred to.ALSO:Metal surfaces are coated with a composition containing an aqueous solution of lithium sodium silicate (see Division C1) together with (a) an inert filler, e.g. asbestos, or pigments, and 50-100 parts of an emulsified polymer per 5-50 parts silicate, or (b) 2-4 parts of a metallic dust, e.g. Zn of particle size 3-25 microns and an alkali metal dichromate, e.g. 0.05-0.1%, optionally together with sand or silica gel, other finely divided metals, e.g. Al or Mg, metal oxides, e.g. Mn, Fe, or Ti, or 0.01-20% alkali metal or ammonium borate or bicarbonate. In Examples 12 and 14 a composition containing polyvinyl acetate or butyl rubber with iron oxide and talc is used to coat steel. In Examples 15-21 a composition containing Zn dust and K dichromate is used to protect steel from contact with water or hydrocarbons. Specification 1,007,482 is referred to.ALSO:A composition containing an aqueous solution of lithium sodium silicate (see Division C1) mixed with glass fibres, asbestos fibres, paper fibres, or sawdust, is applied as a coating by trowel (see Examples 8 and 9). An emulsified polymer such as polyvinyl acetate or chloride or butyl rubber may be incorporated into the aqueous solution of lithium sodium silicate together with inert fillers, e.g. asbestos or pigments. 50-100 parts polymer are used per 5-50 parts silicate. The composition may be applied to metal, concrete, brick or plaster by brush, roller or spray. Examples 12 and 14 relate to the use of polyvinyl acetate or butyl rubber with iron oxide and talc. Specification 1,007,482 is referred to.ALSO:An aqueous solution of lithium sodium silicate, in which the molar amounts of Li2O1Na2O, and SiO2 are 0.75-1, 0.05-0.25, and 2.5-5.0 respectively, is prepared by mixing LiOH, NaOH, silicic acid or silica gel, and water, heating at 75-250 DEG C., and cooling to 20-30 DEG C. The rate of cooling is preferably decreased after 95 DEG C. The solution may contain 10-45% of the Li-Na silicate. Specification 1,007,482 is referred to.ALSO:An aqueous solution of lithium sodium silicate [see Division C1] is used to impregnate cotton fabric and paper (Ex. 2) and asbestos (Ex. 3), or as an adhesive for sticking pieces of cardboard together (Ex. 10). A dye may be incorporated (Ex. 4). The solution may be applied by spray, brush, roller, or dipping, under pressure or vacuum and dried by evaporation. It is said to render the material resistant to fire, water, wear, weather high temperatures, and biological decomposition. Glass fibres may be bound using the aqueous solution of lithium sodium silicate (see Ex. 7). Specification 1,007,482 is referred to.ALSO:An aqueous solution of lithium sodium silicate (see Division C1) is used to coat asbestos fibres (Example 8), paper fibres (Example 9), saw-dust, wood, plastics, glass, metals, concrete or brick. The solution may contain 5-80% fillers, e.g. casein, clay, sugars, aluminates, or asbestos, and 0,01-3% curing agents, e.g. KCl, KBr, or borax. It may be applied by brush, dip, roller, or spray. The Li-Na silicate solution may contain 2-4 parts of a metallic dust, e.g. Zn of particle size 3-25 microns, and an alkali metal dichromate, e.g. 0,05-0,10%, optionally together with sand or silicon gel, other finely divided metals, e.g. Al or Mg, metal oxides, e.g. Mn, Fe, or Ti, and o,01-20% alkali metal or ammonium borate or bicarbonate; and is used to protect metal surfaces in contact with water or hydrocarbons. Examples 15-21 relate to coating steel, e.g. a sandblasted steel panel, with a Li-Na silicate solution containing Zn dust and K dichromate. Specification 1,007,482 is referred to.ALSO:An aqueous solution of lithium sodium silicate (see Division C1) is used to protect wood e.g. pine, oak, and fir, against rot, termites and wood borers (see Example 5). The coating may be applied by spray, brush, roller, or dipping, under pressure or vacuum, and is dried by evaporation. Specification 1,007,482 is referred to.

    摘要： A method and Bridge in a Provider Backbone Bridge Network, PBBN, for enabling frames from a Higher Layer Entity attached alternatively to a Provider Instance Port on an I-Component of a Backbone Edge Bridge or to a Customer Backbone Port on a B-Component of the Backbone Edge Bridge, to reach an intended entity in the PBBN. A Virtual Instance Port Service Access Point, VIP SAP, is configured for every VIP and every Higher Layer Entity configured on the I-Component. An Enhanced VIP Port Connectivity function utilizes the VIP SAP to tunnel customer-initiated Layer 2 Control Protocols, L2CPs. A Special Multiplexed SAP handles the frames of the Higher Layer Entity, and is assigned an I-SID value that is universally recognized to identify the L2CPs. A Service Instance Multiplex Entity utilizes the Special Multiplexed SAP to transfer frames between the Provider Instance Port or the Customer Backbone Port and the entity inside the PBBN.
