Title: New hydrolysed copolymers of ethene and alkenyl esters and a process for the preparation thereof
IPC: C08F8/12
Filed: 1966-07-25
Abstract: Copolymers of (1) ethylene, (2) at least one vinyl- and/or 1-alkyl vinyl ester of a carboxylic acid whose alpha-carbon atom is primary or saturated secondary (3) at least one vinyl- and/or 1-alkyl vinyl ester of a carboxylic acid, in which at least one of the carbon atoms bound directly to the carboxylic group is branched, and (4) optionally one or more other ethylenically unsaturated monomers, in which copolymers (2) and (3) may be identical, are partially or completely hydrolysed.  Suitable components (3) are esters of pivalic acid, 1,1,3,3-tetramethylbutanecarboxylic acid, 1,2-dimethyl - 1 - isopropylpropane carboxylic acid, and 1,1,4-trimethyl pentane carboxylic acid. Suitable components (2) are esters of acetic and oleic acids.  Isopropenyl acetate may be used alone, in which case (2) and (3) are identical. The hydrolysis may be effected by alkalis e.g. NaOH, KOH, LiOH, (CH3)4.N.OH, acids e.g. H2SO4, H3PO4, p-toluene sulphonic acid, HCl, while partial hydrolysis may be effected by using H2SO4 together with CH3.OH or C2H5OH.  The polymer to be hydrolysed may be obtained by conventional techniques.  The new polymers resulting from this process contain units of formula -[-CH2-CH2-]- and units of formula <FORM:1094087/C3/1> where R5 represents an alkyl group and X an hydroxyl or metal alcoholate group, optionally with units of formula <FORM:1094087/C3/2> where R3 is alkyl, and R4 an hydrocarbyl group whose carbon atom bound to the C=O group is primary or secondary.  Other new polymers have units of formula -[-CH2-CH2-]-, units of formula <FORM:1094087/C3/3> and units of formula <FORM:1094087/C3/4> where R1, R15 are hydrogen or alkyl, X is hydroxyl or metal alcoholate group, and R2 is a hydrocarbyl group whose carbon atom bound to the C=O group is quaternary or tertiary, optionally with units of formula <FORM:1094087/C3/5> in which R31 is hydrogen or alkyl, and R4 is a hydrocarbyl group whose carbon bound to the C=O group is primary or secondary.  Units from other monomers may be incorporated, and if such groups have an acid group it may be reacted with metal compounds to give the corresponding salts. Numerous after-treatments of the hydrolysis products are also specified. The new polymers may be compounded with pigments, plasticizers, waxes, dyes, resins and fillers, and may be vulcanized. In the examples, details of various copolymerizations in an autoclave are given, there being successive addition of ethylene and rotation of the autoclave. In examples (1), (3) and (4) vinyl pivalate/vinyl acetate/ethylene copolymers are formed; (2) vinyl pivalate/vinyl acetate/ethylene/norbornadiene are copolymerized; and (5) ethylene/isopropenyl acetate copolymers are formed.  The copolymers are then hydrolysed by saponifying solutions of the copolymers in toluene with solutions of KOH in CH3.OH. Finally the copolymers are vulcanized using a standard recipe with triallyl cyanurate as vulcanizing agent and dicumyl peroxide as an activator.

Title: Improvements relating to machines for cutting tobacco
IPC: A24B7/02
Filed: 1936-12-04
Abstract: 486,046. Linkages for conveying circular motion. LEGG, Ltd., R., and SCHREIBER, P. Q. R. Dec. 4, 1936, No. 33368. [Class 80 (iii)] [Also in Group I] In a tobacco-cutting machine, the knife 18 is secured to a frame 20 which is connected to three or more cranks in such manner that the edge of the knife is square with the crank axes so that the knife keeps in one plane. The cranks each have a weight 46 to balance the revolving and reciprocating masses. As shown, the frame 20 is connected to four cranks 30, 32, 34, 36, one only of which is driven. As the knife becomes smaller through grinding, and is repositioned, the balance is affected. Compensating means are therefore provided comprising four cylinders 92, mounted on the frame 20, containing pistons 94 separating lower water spaces from upper air spaces. The cylinders are connected by flexible connections 98 to a water supply pipe 96, and by flexible connections 104 to a pipe 102 leading to an air reservoir 100 which is connected to a pressure gauge 108. As the height of the knife is reduced by grinding, it is necessary to admit more water to the cylinders 92, the rise of the pistons 94 causing an increase in air pressure which is registered on the gauge 108 which may be calibrated in inches of height of the knife. The cranks 30, 32, 34, 36 are arranged on shafts 38, 40, 42, 44 longitudinally slidable and revoluble in ball bearings, and each shaft carries, between its bearings, a ball-bearing thrust block.

Abstract: 392,984. Winches ; self-sustaining gear. EAST FERRY ROAD ENGINEERING WORKS CO., Ltd., East Ferry Road, Millwall, London, and KIBBLER, H., Cleveland, St. John's Road, Loughton, Essex. Dec. 8, 1931, No. 34002. [Class 78 (v).] In a self-sustaining power winch for hoisting or adjusting a heavy discharge shoot into which coal is tipped from a wagon or truck, the drum a is driven from a hydraulic or other engine b by means of a screwed sleeve d<1> keyed on the crank shaft c engaging a nut e secured within the drum. On hoisting, the sleeve at first screws into the nut until further relative movement is prevented by engagement between friction surfaces on a member f on the drum and a disc h loosely mounted on the boss of the sleeve d<1>, and driving connection is thus established between the engine and the drum. The disc h is provided with ratchet teeth h<1> engaging a pawl i and can rotate only in the direction for hoisting. The load cannot overrun the engine while lowering, or run down while the engine is stopped since the corresponding rotation of the nut e on the sleeve d<1> clamps the member f against the disc h. As shown, the engine b comprises three oscillating cylinders set at 120‹ driving the same crank. The drum may be held, independently of the self-sustaining gear, by a pawl k which may be released by a rod connected with the lowering valve. Specification 196,080, [Class 78 (v), Winding and paying-out apparatus &c.], is referred to.
