Abstract: 357,323. Fabric take-up device for knitting-machines. MELLOR BROMLEY & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A., Minotaur Works, St. Saviour's Road East, Leicester. July 23, 1930, No. 22201. [Class 74 (ii).] The take-down mechanism includes duplicate ratchets 1, 1a made fast to spindles of the gripping rollers 3, 3a which are mounted to be relatively movable. Pinions 3b, 3c depending on which mechanism is operative, drive the rollers. The ratchets and pinions are carried by brackets 6 attached to a plate 7 rotatable about a vertical axis. Each set of driving pawls is carried by arms 5, 5a on which are mounted rollers 15 for engagement with both sides of a stationary adjustable race 16. The inclination of the ring, as determined by a hand-operated screw 18 or automatically determines the rate of feed. The duplicate racking units provided are arranged to come in action alternately, so that the rollers are continuously driven. The ratchets may be of the friction-driven type. In another arrangement (not shown) sets of pawls are carried by toothed discs meshing with a common pinion. The discs are oscillated by cam or equivalent means fixed to the needle cylinder so that one set of pawls makes an operative stroke while the other set is on the reverse stroke. In place of the adjustable ring 16 there may be used driving gear in which one element is a crank pin adjustable in relation to the centre about which it revolves.

Title: Production of saturated cyclic dicarboxylic anhydrides
Inventor: SCHULZ ALFRED
IPC: C07C51/567
Filed: 1963-06-05
Abstract: Saturated cyclic dicarboxylic anhydrides containing 4-8 carbon atoms are prepared by the liquid phase hydrogenation of the corresponding olefinically unsaturated anhydrides with molecular hydrogen or a gas containing molecular hydrogen over a catalyst comprising copper, cobalt and/or nickel tungstates, molybdates, chromates and/or vanadates.  Suitable starting materials are maleic anhydride and its alkyl substituted derivatives, e.g. vitaconic or citraconic anhydride, and tetrahydrophthalic anhydride. The hydrogenation is optionally effected in the presence of an inert solvent, e.g. ethers, cyclic hydrocarbons, esters or cyclic esters, dioxan being preferred. The catalyst may be in powdered or moulded form or be supported on carriers, e.g. silicic acid, silicates, clay or synthetic aluminium oxide.  The reduction may be effected at temperatures between 0-250 DEG  C., preferably 20-170 DEG  C., and at pressures ranging from atmospheric to 300 atm., preferably 10-250 atm.  The process may be carried out continuously or batchwise. Examples describe the hydrogenation of maleic anhydride in dioxan solution using (1) copper molybdate, (2) copper chromate, (3) cobalt molybdate and (5) nickel molybdate as catalysts; the hydrogenation of molten maleic anhydride using (4) copper molybdate catalyst; the hydrogenation of tetrahydrophthalic anhydride using (6) nickel molybdate and (7) a mixture of nickel and copper tungstates as catalysts.ALSO:Catalysts for the hydrogenation of unsaturated cyclic anhydrides are the single substances or mixtures of the compounds comprising the molybdate, tungstates, chromates and/or vanadates of copper, cobalt and/or nickel.  The catalyst may be in powdered or moulded form or supported on a carrier, e.g. silicic acid, silicates, clay or synthetic aluminium oxide.  When a carrier is used it is preferred to develop the catalyst on the carrier.
