Title: Process for the treatment of rubber latex and the like
IPC: C08C1/065
Filed: 1936-12-22
Abstract: Coarse suspensions of rubber are obtained by adding coagulant to latex in two stages, the amount added in the first stage being insufficient to produce flocculation and the total amount being greater than that necessary to produce flocculation if added in one stage.  Different coagulants may be used in the two stages, e.g. a substantially insoluble coagulant such as freshly precipitated calcium phosphate, bolus alba, artificial zeolites of calcium and aluminium may be used in the first stage, followed by a soluble salt of a di- or polyvalent metal such as calcium formate.  The rubber dispersions may contain wetting agents. Coherent films of rubber may be obtained by filtering the treated dispersions through porous moulds.

Abstract: 1365557 Grafted polyvinyl alcohol; block copolymerized polyvinyl alcohol DAICEL Ltd 27 July 1971 [31 July 1970] 35212/71 Headings C3G and C3P A process for preparing an aqueous emulsion of a graft or block copolymer having a high solid content and a high film-forming property comprises the steps of graft or block copolymerizing, in the presence of a tetravalent cerium salt as an initiator, in an aqueous reaction mixture, (1) 82-65 parts by weight of a polymerizable monomer as defined herein, and (2) 18-35 parts by weight of polyvinyl alcohol having an average degree of polymerization in the range 450-1200 and a degree of saponification in the range 96-99%, the reaction mixture containing 22-32% by weight of reactants (1) and (2), calculated as the solids, and 70-85% by weight of the total quantity of polyvinyl alcohol being added to the reaction mixture during the initial stage of the graft or block copolymerization reaction and the remainder of the polyvinyl alcohol being added during or after completion of the ageing of the graft or block copolymer. The tetravalent cerium salt may be selected from cerium sulphate, cerium nitrate, ammonium cerium sulphate, ammonium cerium nitrate, ammonium cerium pyrophosphate and cerium iodide. The cerium salt may be added in acidified aqueous solution in amount 0À05-2 molar per cent based on the vinyl monomer. Preferably 5-30% by weight of the cerium salt is added during the initial stage of the graft or block copolymerization, 5-15% by weight during ageing of the graft or block copolymer, and the balance during the progress of the graft or block copolymerization reaction. The term " polymerizable monomer " is defined by reference to a long list of unsaturated monomers. Preferably the polymerizable monomer comprises a mixture of 5-70% by weight of a monomer yielding a polymer having a glass transition temperature below 10 C., e.g. alkyl acrylates, alkyl (C 5 -C 12 ) methacrylates, vinyl esters of fatty acids (C 3 -C 18 ) and the balance a monomer yielding a polymer having a glass transition temperature above 30 C., e.g. methyl methacrylate, acrylonitrile, styrene and vinyl chloride. The polyvinyl alcohol may be a blend of two or more alcohols. The examples refer to the use of the following monomer mixes, viz.: styrene / acrylonitrile / methyl methacrylate / methyl acrylate (1, 7-10, 11, 12, 13-14); styrene/n-butyl acrylate (2, 3, 4); acrylonitrile/ methyl methacrylate/n-butyl acrylate (5); and methyl methacrylate/n-butyl acrylate (6). The proportions of the monomers, the amounts of polyvinyl alcohol added in the separate stages, and the amounts of catalyst added in separate steps are varied. The specific catalyst used is ammonium cerium nitrate.

[Class 106 (i)] In an autographic recorder of the kind described in Specification 229,616, [Class 16], wherein the filing of the record strip 13 in folded condition is ensured by a hook 21 engaging central perforations in alternate forms, the filing space is increased by the provision of a guide member 14 arranged in front of the feed discs 22, mechanism being provided to catch and hold the leading edges of all centrally perforated forms for a sufficient period to ensure that they are inverted before proceeding over the guide to the filing compartment. The leading edge of each centrally perforated form is directed by the hook into a channel member 17 carried by arms 18 and urged upwardly by a weak spring, the hook being then withdrawn in usual manner. Later in the operation, the channel is depressed by a stud 27 on one of the feed discs, and the leading edge thus freed bears against the feed discs. Finally, upon its return, the channel bears with its right-hand flange against the underside of the forms to assist their movement over the guide during the next operation. If desired, this latter function of the channel may be effected by an additional member. A spring 30 is provided at the bottom of the filing compartment to aid the stacking of the first forms delivered. Where the filing compartment is comparatively deep, it may be provided with a depressible false bottom. Specification 136,116, [Class 16], also is referred to.

Title: Improvements in or relating to the production of vinyl acetate
Inventor: GODIN GEORGE WILLIAM
IPC: C07C69/01
Filed: 1964-09-04
Abstract: Vinyl acetate and acetic acid are prepared by reacting ethylene and a molecular oxygen containing gas with a mixture containing acetic acid, acetate ions, a platinum group metal catalyst and a cobalt or manganese salt.  A redox system, e.g. a ferric/ferrous or a cupric/cuprous system may be present and then the process may be in two stages.  In the first stage ethylene is reacted with a mixture of acetic acid, acetate ions, the redox system, the platinum group and oxidation catalyst, and in the second stage after removal of the vinyl acetate and acetaldehyde recycle, the mixture is contacted with oxygen-containing gas and returned to the first stage.  Platinum metal or palladous chloride or acetate may be used and the acetate ions may be derived from alkali metal, alkaline earth metal or copper salts.
