Patent GB-854987-A (GB)
Title: Manufacture of shaped products of polyvinyl alcohol
IPC: C08L29/04
Filed: 1957-02-25
Abstract: Colourless shaped products, e.g. fibres, filaments and films, that are heat resistant and fast to boiling, are produced by wet or dry spinning an aqueous solution of polyvinyl alcohol containing 0,5-8%, calculated on the weight of dissolved polyvinyl alcohol, of one or more water-soluble polybasic acids of linear polymeric structure. Specified polybasic acids are polyacrylic acid, polymethacrylic acid, polyvinyl phosphoric acid, polyvinyl sulphonic acid, cellulose glycollic acid (carboxy methyl cellulose), the reaction product obtained from polyvinyl alcohol and acrylonitrile after saponification of the nitrile group and water-soluble acid copolymers, e.g. those obtained from maleic acid and styrene, acrylic acid and acrylic acid esters, methacrylic acid and methacrylic acid esters, fumaric acid and vinyl acetate, and vinyl methyl ether and maleic anhydride.  The shaped products may be stretched in the cold and/or hot, heat-treated and subsequently treated with hardening agents, e.g. formaldehyde, which preferably contain inorganic salts, e.g. sodium sulphate, and acids, e.g. sulphuric acid, in concentrations such that considerable shrinkage does not occur during the hardening process.

Title: Positioning apparatus
IPC: B23Q35/18
Filed: 1953-01-30
Abstract: 731,633. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Jan. 30, 1953 [Feb. 20, 1952], No. 2782/53. Class 135. [Also in Group XXXVIII] In a correspondence control system, (see Group XXXVIII) in which a machine tool head 108, Fig. 1, is positionally controlled by a fluid-pressure servomotor in accordance with thecontourofa master cam 10, the servomotor is operated by an electric error signal derived from a transformer 14 having a movable core 12. The error signal is proportional to the relative displacement of the transformer core and windings and, after amplification and detection, causes the pivotal movement of a torque motor armature 40. Pistons 48, 50 controlled by the armature and each fitted with spools 64, 66, 68 are thus caused to move in opposite directions. A pair of ports 58, 60 are then exposed so that fluid pressure at entry and exit conduits 54, 56 causes the operation of a hydraulic ram 104 over conduits 98, 100. By means of a link 106, the ram effects consequential movement of the machine tool head and the transformer windings, the windings being displaced in such a direction as to reduce the error signal to zero. In the servomotor, the arrangement of spools 64, 66 with respect to ports 54, 58 establishes an inherent selfclosing force in the piston; this force is, however, substantially neutralized by the provision of curved surfaces adjacent to the port 60. As shown in Fig. 3, the spools 66, 68 are joined by a curved surface 70 which is shaped as shown with the surface 72 initially inclined to the axis of the piston at an angle of about 69 degrees, while the surface 74 has a substantially lesser slope.

Abstract: Azo dyes and soluble chromium compounds thereof; pyrazolones.-Certain of the dyestuffs containing chromium described in the parent Specification are obtained by first converting the pyrazolones from the aminoarylsalicylsulphones into their chromium compounds by treatment with agents yielding chromium and thereafter coupling with aromatic diazo compounds containing no hydroxy group in o-position to the diazotized amino group.  The following examples are specified: (1) The 3-methylpyrazolone, obtainable from 21-hydrazino-411-oxy-311-carboxydiphenylsulphone -41-sulphonic acid and acetoacetic ester is boiled for 2 hours under reflux with an aqueous solution of chromium formate, and the product is coupled in sodium acetate solution with diazotized 2-chloro-4-aminotoluene; the product dyes wool from an acid bath an even clear greenish yellow shade fast to light, fulling, perspiration, carbonization, and steaming; (2) The 3-methylpyrazolone obtainable from 21-hydrazino-211-oxy-311-carboxy - 511-methyldiphenylsulphone-41-sulphonic acid and acetoacetic ester is converted into the chromium compound as in (1), and the product is coupled in sodium acetate solution with diazotized 2-aminotoluene or with diazotized 2-aminobenzoic acid; the products give on wool yellow dyeings similar to those in (1). Chromed pyrazolone-3-carboxylic acids and esters thereof derived from aminoarylsalicylsulphones may be similarly coupled. Specification 245,765, [Class 2 (iii), Dyes &c.], is referred to.

Abstract: 1506971 Rod cooling and coiling systems MORGARDSHAMMAR AB 27 Jan 1976 [27 Jan 1975] 03042/76 Heading D1T A system for cooling and coiling a metal rod as it leaves a rod rolling stand M comprises a coiler C, Fig. 1, a plurality of coil receiving supports 23 indexable beneath the coiler, and means to move completed coils to cars 61 at a receiving location, the cars being movable from the receiving location to a coil-removal station and back again, a bundling mechanism 82 being located upstream of the removal station, and means at the removal station to remove bundled coils which means, together with the coil moving means being respective lifting mechanisms movable along aligned paths extending transverse to the path of the cars. The support 23 is located in a cooling bath 25 which is indexed as a whole to avoid uneven cooling, the bath being filled with hot water to provide the necessary heat treatment for the metal. After a coil has been deposited in the bath it is indexed to a station Y where a hoist lifts and transfers it to a car 61. The plurality of cars 61 are arranged on parallel sets of tracks and are moved by endless conveyer chains 92 running beside the tracks which are engaged by grippers 90 on each car. the grippers are released adjacent the hoist to stop the car in order to receive a coil. The grippers are also released when a stationary car is encountered ahead. At the ends of the tracks turntables 106, 150, Fig. 2, transfer the cars to the other respective track to move in the opposite direction and hence continuously circulate. At the bundling station 82 on the return track the coils are wrapped in wire and at station 82a a further hoist transfers them on to a slat conveyor 90. Rod R is fed to the coiler between two guides 2, 3, Fig. 1. A sensor 4 detects the position of the rod between the guides and controls the speed of delivery rollers 6 to maintain the rod out of contact with either guide. Detents 35. 36 retain the first few turns of coil while the support is moving into position underneath.
