Abstract: 1278627 Film winding mechanism GAF CORP 19 June 1969 [5 July 1968] 31164/69 Heading G2E A drive system for winding material from a first reel on to a second reel includes a drive motor; a spindle 10 to which the centre of the first reel can be attached; a roller 16 shiftably mounted adjacent the spindle and selectively engageable therewith; and control means for placing the roller 16 in winding contact with the spindle 10 for an instant on switching from a winding mode to an "off" or "stop" position so that the material is taut between the reels before winding ceases. The spindle 10 may be driven either directly by the "fast" roller 16 or through a crossed belt 20 by a "slow" roller 18 and a spindle 22 may be driven directly by a "fast" roller 26 or by a "slow" roller 27 through a bolt 30, the rollers being mounted on pivoting plates 14, 23 which are positioned by arms 36, 45 respectively. The arm 45 is movable by a lever 52 which acts as a cam follower as does the arm 36. The rollers 16, 26 are belt-driven from engaging gears 58, 64 which in turn are belt-driven from a drive wheel 62 which is driven in one direction through a belt 68 or by direct contact in the opposite direction by a shiftable roller 70. A series of cams  mounted on a shaft (94) Figs. 7 to 13 (not shown) positions arms 36, 52 and the roller 70 according to the operating mode required, and further cams operate the projection gate, the motor switch and a heat shield to protect film in the "still" mode. As the cams are rotated anti-clockwise (as seen) through 360 degrees, the operating modes passed through are "off", "forward", "still", "reverse", "stop", "fast forward", "stop" and "rewind". The belt 68 is slackened on movement to the "off" or "stop" position by slight upward movement of the roller 70, thereby disconnecting the drive. However, engagement between rollers 16, 26 and respective spindles 10, 22 is established by means of the action of the cams on the shaft (94) upon the arms 36, 52 just prior to slackening the belt 68 thereby momentarily urging the spindles in film winding directions. The rollers 16, 26 remain in contact with the spindles after the belt 68 has slackened to restrain the spindles from further movement.

Title: Cross-Linkable Acrylonitrile Copolymers and production thereof
IPC: C08F20/58
Filed: 1966-07-12
Abstract: 1,152,029. Preparation of cross-linkable acrylonitrile copolymers. JAPAN EXLAN CO. Ltd. 12 July, 1966 [14 July, 1965 (2)], No. 31338/66. Heading C3P. Cross-linkable acrylonitrile copolymers are prepared by copolymerizing a monomeric mixture comprising acrylonitrile, in an amount of at least 60% by weight of the mixture, and N- methylolacrylamide in an aqueous medium at a pH of not more than 4 and in the presence of a redox catalyst in which the reducing component is a water-soluble sulphoxy compound, there being present in the polymerization medium at least 1/ 3  of a mole, in excess of any which may be consumed during the redox reaction, of at least one water-soluble inorganic salt per mole of N-methylolacrylamide. Said salt content may be provided by using an excess of a redox catalyst component, e.g. a sulphite, bisulphite, metabisulphite, hydrosulphite or thiosulphate reducing component, or an oxidizing component such as ammonium or potassium persulphate or sodium or potassium chlorate. Alternatively, a non-catalytic salt may be used, e.g. a water-soluble chloride, sulphate or nitrate of sodium, potassium, lithium or calcium; in such cases, the oxidizing component of the redox catalyst may be hydrogen peroxide as well as the above-mentioned oxidizing salts. The monomeric mixture used may optionally contain one or more other monomers, e.g. methyl or ethyl (meth)acrylate, vinyl formate or acetate, and sodium (meth)allyl sulphonate. The polymerization process can be effected in continuous manner (see Examples 8-10). To prevent premature cross-linking when drying the copolymer slurry obtained by the polymerization, the pH of the slurry can be adjusted to from 4À5-6À0 by addition of an inorganic alkali or an alkaline earth metal compound, whereby terminal sulphonate groups in the copolymer (resulting from the redox sulphoxy component) are converted from the H form to the salt form. Fibres obtained from spinning solutions of the copolymers in solvents such as dimethyl formamide, dimethyl sulphoxide or concentrated aqueous sodium rhodonate (thiocyanate) can be subsequently cross-linked to improve the physical properties of the fibres.
