Abstract: 1,073,149. Winding ropes and yarns; controlling winding speed. VSESOJUZNY NAUCHNO - ISSLEDOVATELSKY INSTITUTE STEKLJANNOGO VOLOKNA. Dec. 10, 1964, No. 50269/64. Heading DID. To ensure a constant take-up speed of glass fibres, rope or yarn on a bobbin 4 a toothed rack 14 supports a roller 12, the roller 12 being biassed by a spring 15 towards the bobbin 4. As the package on the bobbin 4 increases in diameter the roller 12 is moved towards the rack 14 to close the contacts 16. Closure of contacts 16 cause a motor 17 to be energized to perform two separate functions, namely:- (a) adjust the setting of a friction disc 8 relatively to a friction disc 9 to slow down the rate of revolution of the bobbin 4; and (b) rotate a drive member 20 coupled to the rack 14 to cause the rack 14 to move away from the roller 12. When the rack 14 has moved slfficiently away from the roller 12 the contact 16 open and the motor 17 stops. A motor 7 drives the friction disc 8.

Abstract: 1,210,537. Deposition of silicon. WESTERN ELECTRIC CO. Inc. 21 Nov., 1967 [15 Dec., 1966], No. 52825/67. Heading C1A. [Also in Division H5] A plurality of articles 10 are treated at a given temperature by supporting them around the inside of a hollow rotatable drum shaped member 16, rotating this drum about its axis so that the articles are forced into close contact with the wall by centrifugal force and then heating the drum so that the articles are heated to the given temperature by conduction of heat from the drum wall. Preferably the rotation axis is vertical, and the articles, which may be wafers, are supported in pockets 17 recessed in the drum wall which pockets may be shaped so that a flat surface of each article e.g. wafer 10 abuts a flat surface 18 on the drum-shaped member, and the exposed surface of the waferisinclined at an angle of less that 15 degrees e.g. 3 degrees to the axis of rotation. A coating material may be deposited on the exposed surfaces of the heated articles from a vapour within the drum which vapour may be introduced via line 28 along the rotation axis of the drum. It is preferred that the wafers are of semi-conductor material e.g. Si, and the vapour is a heat decomposable compound of this semi-conductor material e.g. silicon tetrachloride in a carrier gas of hydrogen. The drum may be heated inductively e.g. by coil 41, and may be surrounded by a container 13 which may be evacuable e.g. by pump 31. The container is preferably surrounded by a fluid cooled Faraday shield 42 which prevents stray electrostatic interference and acts as a heat shield. The shield 42, the coil 41 and container 13 may be raised as a unit on guides 44 to load and unload the drum. The drum is preferably made of graphite and may comprise individual ring shaped sections 15 which when superimposed on each other via spacers 21 form a drum rotatable as a single unit by base-plate 14. The base-plate is driven through flange 24 on axis 26 which rotates in bearing 27, being driven from motor 38 via magnetic clutch 39 and gears 34, 36. The reactant gases are supplied via inlet 29.

The copolymers may be prepared by emulsion or solution polymerization processes using a free radical catalyst, such as a peroxide or azo compound or a peroxide/reducing agent redox system. Emulsion polymerization is preferably effected at a pH of 3-8À5 using an emulsifier such as sodium lauryl sulphate, glycerol monooleate, alkylphenoxypolyoxyethylene glycol or sulphonated castor oil. The water-sensitivity of the copolymer may be increased by hydrolysing some or all of the vinyl ester groups to hydroxyl groups. The copolymer emulsions or solutions can be applied to textile materials or fibres produced from acrylonitrile polymers to provide the textile with a cashmere-like hand. The treated textile is heated to 90-150‹ C. to cross-link the copolymer, for which purpose an acid or an acidic salt or a basic catalyst (e.g. a tris (dialkylaminoalkyl) phenol) may be present.
