Title: Improvements in or relating to a method and apparatus for manufacturing knitted fabrics
IPC: D04B7/04
Filed: 1953-06-10
Abstract: 774,175. Knitting; fashioning. DUBIED & CIE, E. June 10, 1953 [June 17, 1952], No. 16034/53. Class 74 (2). Fashioning is carried out, on a parallel machine having a constant stroke of the thread guide carrier driving carriage, by a method wherein the stroke of the active thread guide carrier is automatically changed only after the fabric has been progressively narrowed or widened by several narrowing or widening cycles over a plurality of courses. Thus, after knitting a 2 x 2 border E with yarn carrier stroke B, the portion F is knitted with carrier stroke C and the portion G with carrier stroke D. Yarn guide carriers 4, 5 are carried in slideway 2 and are reciprocated by one or other, as required, of spring urged, axially adjustable drivers 8, 9, borne on a carriage 10. The carrier 4 bears shoulders 6, 6b, 6a through which it may be driven by, respectively, driver 8, driver 9, and either driver. Carrier 5 bears shoulders 6c, 6d, lying respectively in the path of driver 8 and those of both drivers. Associated with these shoulders are ramps 7, 7b, 7a, 7c, 7d, up which the drivers can run. Similar ramps are provided on stops 11, 12, 13, 14, carried in slideways 2, 3. To produce portion E, carrier 5 is brought by driver 8 from a starting position at the right-hand side of the machine, and is thereafter traversed each time to the left by engagement of driver 8 with shoulder 6c, until that driver is disengaged therefrom by ramp 7a, and is traversed each time to the right by engagement of driver 9 with shoulder 6d, until it is disengaged by the ramp on stop 14. At the end of this portion, the carrier 5 is returned, by driver 8, to its starting position, determined by stop 12. To produce portion F, carrier 4 is moved from its starting position, at the lefthand side of the machine, and traversed to the right by engagement of driver 8 with shoulder 6a. Driver 8 is then disengaged and the carrier thereafter traverses both to left and to right by driving engaging shoulders 6b, 6a successively and being disengaged therefrom, at the end of each traverse, by the ramps on stops 13, 14. For the last stroke from right to left driver 9 is disengaged and the carrier is returned to its starting position (determined by stop 11) by driver 8. To produce portion G, the carrier 4 is traversed in both directions by driver 8, which engages with shoulders 6a and 6 and is disengaged therefrom, at the end of traverses to right and left respectively, by ramp 7c on carrier 5 and the ramp on stop 11.

Title: Regeneration of catalyst solutions containing cobalt sulphate
IPC: C07C27/22
Filed: 1953-06-11
Abstract: A cobalt sulphate-containing catalyst solution, which has become spent in the production of cobalt carbonyl hydride for the catalytic addition of hydrogen and carbon monoxide to an unsaturated organic compound in the presence of metallic iron, is regenerated by the addition of cobalt carbonate in a quantity substantially equivalent to the iron in the solution and intensively stirring the mixture (see Group III).  In an example a cobalt sulphate-magnesium sulphate solution is used for the synthesis of aldehyde by the addition of water gas to a C12 olefin at a temperature of 150 DEG  C. and a pressure of about 200 kg./sg.cm. in the presence of metallic iron.ALSO:A cobalt sulphate-containing catalyst solution, which has become spent in the production of cobalt carbonyl hydride for the catalytic addition of hydrogen and carbon monoxide to an unsaturated organic compound in the presence of metallic iron (see Group IV (b), is regenerated by the addition of cobalt carbonate in a quantity substantially equivalent to the iron in the solution and intensively stirring the mixture.  Stirring may be effected by blowing in air or by other means.  The cobalt content of the solution is restored and the dissolved iron is precipitated and filtered off.  An example describes the treatment of a solution which contains magnesium sulphate as well as cobalt sulphate.

Abstract: 905,012. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 12, 1959 [May 20, 1958], No. 16180/58. Class 38 (5). In a circulating current system for a power transformer 1 having voltage regulating tappings, incorrect operation due to unbalance caused by tap-changing is prevented by shunting the differential relay 7 by a winding of a transductor 9 having a control winding 10 supplied with a current proportional to that flowing in the power transformer. In Fig. 1, the control winding 10 is supplied through a rectifier 11 from a current transformer 12, but in Fig. 3 the control winding 10 is connected in the circulating current circuit and the relay 7 is energized from an auxiliary transformer 13. Fig. 2 (not shown) illustrates a polyphase arrangement including low-set timedelay relays and instantaneously operating high-set relays. In each case the transductor control winding or windings is or are associated with the primary side of the power transformer 1 so that the shunting effect is controlled by the magnetizing current of the power transformer when initially put into operation to prevent incorrect operation when switching in the power transformer.

Abstract: 544,665. Valves. JENNINGS, H. W. K. (Berner L.). Nov. 14, 1940, No. 16502. [Class 135] [Also in Group XXI] In an earth-excavating scraper in which a bowl, mounted in a wheeled frame, is movable into scraping, carrying and dumping positions, and has an apron forming the front wall of the bowl and movable into open and closed positions, the means for moving the bowl and apron are controlled so that the apron can be closed only when the bowl is in or below its normal carrying position, and the bowl can be moved to dumping position only when the apron is open. The wheeled frame 11, Fig. 1, supports a scraper bowl 25 which is raised or lowered between digging and carrying positions by a hydraulic ram 39 acting through an arm 35 on a crossshaft 30 carried by the frame and fixed to arms 31 pivoted to the bowl at 32. Co-operating with arms 31 in supporting the bowl are hydraulic rams 50 one on each side of the machine and adapted to move the bowl to dumping position. At the front of the bowl is an apron 65, with reinforcements 69, 70 carried by links 75 pivoted to the frame at 73 : a hydraulic ram 82 is pivoted to the frame and apron at 84, 81 respectively and is adapted to move the apron to closed and open positions, the apron being guided in a desired path by cam means 91 carried thereby and engaging rollers 90 on the crossshaft 30. The hydraulic rams 50, 82 are controlled by a common valve 115, Fig. 6, one side of which is connected through pipes 88, 118 to the front ends of the rams while the other side is connected through pipes 87, 61 to the rear end of the rams ; the pipes 88, 61 contain control valves 120, 121, each comprising a piston 124, Fig. 4, held between weak and strong springs 126, 125 and controlling passages 128, 129. When the valve 115 opens the pressure fluid supply to pipes 88, 118 fluid first passes through pipe 118 to rams 50 to return the bowl from dumping position, and pressure is then built up to move piston 124 of valve 120 against the resistance of spring 125, when fluid passes to ram 82 to close the apron; when the valve 115 opens the fluid supply to pipes 87, 61 fluid first passes through pipe 87 to ram 82 to open the apron and pressure is then built up to open valve 121, when fluid passes to rams 50 to tilt the bowl to dumping position. The bowl may be tilted to dumping position and then lowered for levelling.
