Filed: 1962-02-02
Abstract: 987,261. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 2, 1962, No. 4193/62. Heading H4K. In an office system provided with central data processing equipment, each subscriber's set HT, MS is connected to the exchange by a 4-wire line li, lu terminating in gates G, and high-speed scanning equipment FE continuously scans the gates G and data receivers Mot. Two data processing units TDb, KDb are provided, the former for dealing with switching data and the latter for office data, and one may serve as a reserve for the other. The occurrence of a telephone call is detected by the scanner FE and notified to the unit TDb which effects the seizure of an idle data receiver Mot. The identities of the calling party and of the receiver Mot are sent to a marker M which controls switching apparatus VU (preferably electronic) to connect the line to Mot. The number set up on a keyset KS is received by Mot and passed to TDb, from which it goes to the marker M. The wanted line is rung from Mot and the selecting apparatus VU is controlled to complete the connection. The scanning of the gates G indicates when either party hangs up and TDb effects release of the connection. On a data call, a switch DO is closed and the connection to Mot is made as before. In this case the data set up on the keyset KS is passed from TDb to KDb for processing, and the result is sent to Mot and thence back to the office machine SM by means of frequency combinations (not including the ringing frequency) which are received by TM. A data call may be interrupted in favour of an incoming telephone call, the data call being resumed in connection with the same receiver Mot provided the switch DO is kept operated. Specification 801,644 is referred to.

Abstract: 290,717. King, G., and Threlfall, R. Feb. 16, 1927. Coating compositions.-Colloidal solutions of silica for coating stone, brick, wood, or other surfaces are obtained by adding water, not in excess, to a solution of an alkyl silicic acid ester in a solvent capable of carrying water in solution or suspension. Preferably the amount of water used is insufficient to decompose the whole of the ester. Pigments may be added to the solution, preferably in admixture with solvents, e.g. cyclohexanol, which do not interfere with the hydrolysis of the ester. Setting may be retarded by the addition of non-volatile or slowly volatile solvents such as carbon tetrachloride, turpentine. bromnaphthalene, fatty oils, shellac, synthetic resins, essential oils, &c. The solution may be added to pyroxyline lacquers as a stiffening or fireproofing agent. The Specification contains many examples of procedure, of which the following is typical-315 litres of a mixture of esters obtained by adding 1.3-1.5 volumes of alcohol to 1 volume of silicon tetrachloride are added gradually with stirring to 135 litres of alcohol.

Filed: 1954-02-17
Abstract: A polymeric material comprises at least two oppositely charged polyelectrolyte polymers united through a plurality of ionic cross-linkages and further having a plurality of covalent cross-linkages uniting them.  Covalent cross-links can be introduced (a) when one or both electrolytes has a cross-linking group such as an epoxy or mercapto group, cross-linking being effected by heating; (b) when one of the polyelectrolytes has a functional group complementary to another functional group in the other polyelectrolyte, e.g. hydroxyl groups and carbalkoxy groups; or (c) by reacting the ionically cross-linked polymer with a polyfunctional reagent such as an alkylene dihalide, an aralkylene dihalide, ethylene oxide, propylene oxide, formaldehyde, dimethylolurea, dimethylolmelamine, a dimethylolurea, a dimercaptan or a glycol.  The polyanionic polymer may be one of those referred to in Specification 762,010 or may preferably be a copolymer of acrylic or methacrylic acid with allyl glycidyl ether, glycidyl methacrylate, butadiene monoepoxide, vinyl glycidyl phthalate, allyl glycidyl maleate, allyl glycidyl phthalate, 4 - vinylcyclohexene monoepoxide, acrylamide, methacrylamide, N-methyl, N-phenyl or N-benzyl acrylamide.  The polycationic polymer may be one of those referred to in Specification 762,010.  The ionically crosslinked polymers are preferably prepared prior to covalent cross-linking by reacting the polyelectrolytes in aqueous solution; their solubilities may be increased by neutralizing the polyanionic polymers with ammonia, sodium hydroxide or potassium hydroxide, and the polycationic polymers with acetic, hydrochloric or sulphuric acid.  The ionically and covalently cross-linked polymers may be aftertreated with salts of polyvalent cations or anions such as barium, calcium, magnesium, aluminium, mercuric or zinc chloride, tin tetrachloride, cadmium acetate, lead nitrate, nickel diacetate, aluminium potassium sulphate, basic chromium sulphate, sodium silicate, sodium cobaltinitrite and sodium chloroplatinate.  The cross-linked polymers may be used for the production of films and filaments and for coating and impregnating fabrics by forming the ion-cross-linked polymer directly on the fabric and heating to introduce the covalent linkages. Specifications 722,258 and 759,863 also are referred to.
