Title: Tensioning device - for winding and unwinding continuous textile elements
Inventor: MELEAD JAMES JOHN
IPC: B65H19/00
Filed: 1972-04-19
Abstract: A continuous textile web passes with a direction change of 180 degrees Around a sesing roller so that changes in web tension exert a horizontal force on the roller. The roller is carried between two link arms each of which is pivotally connected, at one end of the lower end of an upper lever pivoted at its upper end, and at the other end fo the upper end of a lower lever pivoted at its lower end whereby the roller can execute horizontal motion. pneumatic rams exert a predetermined force on the upper arm so that if the web tension increases the roller, the therefore the upper arm, move against the action of the rams, whilst if the web tension decreases the rams move the upper arm in the opposite direction. Movement of the upper arm is measured to indicate web tension changes.

Abstract: 1365436 Alkenylsulphonate copolymers MONTECATINI EDISON SpA 10 July 1972 [8 July 1971] 32172/72 Heading C3P [Also in Divisions B5 and D1] Copolymers useful, e.g. in the manufacture of cation-permoselective membranes are derived from (a) 5-80 mole per cent of an alkenesulphonate of the formula where n is 0 or 1, M is a cation of a mono-, di- or tri-valent metal or an ammonium ion, which may have up to four organic substituents, and z is the valency of M; (b) 5-95 mole per cent of vinylidene chloride or α-chloroacrylonitrile; and optionally (c) 0-90 mole per cent of another monomer containing a CH 2 =C= group. The polymers are prepared by conventional methods, e.g. solution polymerization in a polar organic solvent such as dimethylsulphoxide. Membranes may be prepared by evaporating a thin layer of a solution of the copolymer, optionally mixed with another polymer containing double bonds or halogen atoms, in a suitable solvent such as dimethylformamide or water and heating the resulting film at a temperature above 120‹ C. to form an insoluble cross-linked product. The copolymers can also be used in other applications requiring the presence of a strongly acidic group and are, for example, receptive to basic dyes. Examples are given of the preparation of copolymers of (a) CH 2 =CH-SO 3 Na or CH 2 =CH-CH 2 -SO 3 Na, (b) CH 2 =CCl 2  or CH 2 =C(CN)Cl and optionally (c) acrylonitrile, methyl vinyl ketone, vinyl dichloroacetate, #- hydroxyethyl acrylate or styrene. Membranes are prepared from these polymers alone or mixed with polyvinylchloride or a butadiene-acrylonitrile copolymer; in one case the polymer solution is used to impregnate a polyethyleneterephthalate mesh so that a supported membrane results.
