Abstract: 1,263,512. Laminates. PIRELLI S.p.A. 28 July, 1969 [3 Aug., 1968], No. 37776/69. Heading B5N. A method of making a leather-like material comprises-applying a polyurethane foam-forming composition to a surface of a supporting sheet, e.g. a silicone resin coated paper, which has been previously coated with a thermoplastic polyurethane resin, placing the coated sheet in an oven maintained at a temperature within the range of from 110‹ to 170‹C. for a period of time necessary to effect foaming and partial cross-linking of the composition and produce a first composite structure; making a second composite structure by impregnating a layer of non- woven fibres, e.g. of polyamide fibres optionally admixed with up to 50% of polyester fibres, with a latex of natural or synthetic rubber, bonding said layer to a knitted fabric of polyamide fibres by a polyurethane adhesive composition to obtain an assembly, passing said assembly through a continuous curing unit for a time sufficient to set the rubber and cross-link the adhesive, applying the knitted fabric surface of the second composite structure to the partially cross-linked polyurethane surface of the first composite structure, heating the resultant assembly in an oven maintained at a temperature of from 110‹ to 170‹ C. for a period of time necessary to complete cross-linking of the partially expanded cross-linked expanded polyurethane and stripping the supporting sheet from the resultant leather-like material. The exemplified polyurethane foam-forming composition comprises a mixture of a polyester or polyether having a molecular weight of 1000 to 4000, a polyisocyanate, a blowing agent, a curing catalyst and a foam-stabilizing agent. The paper sheet may be grained or embossed on the surface to be coated.

Title: Separation of hydrocarbons
IPC: C07C7/156
Filed: 1969-07-29
Abstract: 1,221,886. Separating hydrocarbons. MONSANTO CO. 29 July, 1969 [29 July, 1968 (3)], No. 38068/69. Heading C5E. Unsaturated hydrocarbons are separated from a hydrocarbon mixture by contacting the mixture with a complex comprising (a) cuprous fluoroborate or fluorophosphate, and (b) an aromatic hydrocarbon or olefin, (b) being different from any unsaturated hydrocarbon in the mixture, thereby to form an extract phase and a raffinate phase, the extract phase being richer in the unsaturated hydrocarbon than the original mixture, and separating the phases. The four principal variants of the process are: A. The separation of an unsaturated aliphatic hydrocarbon from an aromatic hydrocarbon. B. The separation of an unsaturated aliphatic hydrocarbon from a saturated aliphatic hydrocarbon. C. The separation of olefinic hydrocarbons according to structure and type (e.g. straight chain or branched chain, position of double bond). D. The separation of a vinyl aromatic hydrocarbon from an alkylaromatic hydrocarbon. A non-complexible hydrocarbon such as a C 2 -C 15  paraffin may be used as diluent to aid in the formation of extract and raffinate phases and/or for further extraction of the extract phases to remove hydrocarbons not complexed with the cuprous salts. The unsaturated hydrocarbons may be displaced from the extract phase by the use of vacuum, heat or by contact with unsaturated hydrocarbons of different M.W. or with vinylaromatic hydrocarbons in amount of at least a molar equivalent. The complexes formed in variant D may be stabilized to prevent polymerization of vinyl aromatics by displacing a portion of the aromatic hydrocarbon from the complex with oxygen or sulphur-containing compounds such as ethers, ketones, sulphones, disulphides, thioethers, thioureas, nitro-compounds and trihydrocarbyl phosphines. The aromatic complexes may also be stabilized by the addition of olefins.

Abstract: 1,157,352. Cutting glass sheets. ASAHI GLASS CO. Ltd. 25 Aug., 1966 [27 Aug., 1965; 2 Nov., 1965], No. 38089/66. Heading C1M. Flaws are marked manually at 3 and the marks detected photo-electrically at 4. This information and that from a speed sensor 13 are fed into a computer 16 into which a cutting list has previously been fed. This controls transverse cutter A and a series of longitudinal cutters B through a time delay circuit. This circuit imposes a delay to permit transit of the sheet to the location of the cutters and this delay may be changed if a reserve cutter (not shown) is  "  used when the main cutter is inoperable. A further delay is imposed on each longitudinal cutter to compensate for its individual operating characteristic and as disclosed one of six preset delays can be matched to the cutter. The longitudinal cutters are solenoid operated through an "AND" gate fed by the delay network and by the computer instruction.
