Title: Warp knitting machine
IPC: D04B23/00
Filed: 1953-05-27
Abstract: 729,978. Knitting-machines. HARTUNG, H. May 27, 1953, No. 14774/53. Class 74 (2). The movement of the thread guides of a warp machine is restricted to a shogging movement actuated by the usual pattern cams or chains, and the needles have a movement in addition to their usual reciprocatory movement whereby they are swung past the thread guides to take the yarns. For this purpose the needle bar is supported at its ends by pins 22, 122 engageable in slots 23, 123 in end plates, which slots when the bar is raised and lowered by eccentric 32 impart the necessary swinging motion to it. Alternatively, the needle-bar and trick bed may be mounted on pivoted arms 40 controlled by a cam 52 to impart the swinging movement, the needle bar in addition being raised and lowered by a cam 50 through plungers 43. In addition to the usual thread guides a series of steel bars 7 may be provided with guide eyes 8 provided in projections 9 which extend between the needles when the needles swing across them. The steel bars 7 are closely spaced together and are operated by springs or levers controlled by pattern cams to effect shogging movement.

[Class 39 (iii)] [Also in Group II and XXII] A multiple spindle, lathe or like machine tool performing operations in succession on a work piece includes a device for heating, e.g. an induction heating coil 34 and also for quenching a surface to harden it and one or more tools adapted to act on said surface before or after the hardening. A series of chucks 6, to receive the articles 7, e.g. wheel hubs, are fixed on pedestals 5 on a turn-table 2 on a base 1. Tools T are mounted in holders 8 on a carriage 10 and moved to and from the article by screws 9, The carriages 10 move in guides on the surface 13 of a prismatic pillar. A tube 14 with a nozzle 15 is connected at its upper end by a flexible tube 16 to a supply of quenching liquid. The tube is moved vertically by a piston 17 in a pneumatic cylinder 19 attached to the part 11 by lugs 20. Concentric with the pipe 14 is a tubular member 23 which carries at its upper end a piston 24 working within the bore 25 of a pneumatic cylinder 26. The tube 23 carries at its lower end a core 30 with a winding 31 grounded to the core at 32. Attached to the lower end 33 of the winding is an induction heating coil 34 wound upon a core 35 carried by the lower end of the tube 23. The coil 34 constitutes the secondary winding of a transformer, the primary of which is formed by a winding 37 in a hollow core 38, power being supplied by wires 40, 41. To harden the inside of the articles 7, the tube 23 is lowered until the coil 34 and core 35 are within the article, and the inner surface of the article is heated by the induction coil 34. After heating, the coil is withdrawn, the nozzle 15 is lowered and liquid is sprayed on the heated surface. The nozzle 15 is finally raised by the actuation of the piston 17 and the table 2 is rotated to bring the next article into position. Specifications 490,514, 503,130 and U.S.A.

Filed: 1917-10-22
Abstract: 166,571. Henderson, Sir J. B. Oct. 22, 1917. Drawings to Specification. Gyroseopic apparatus. - In a gyro compass or gyro bearing-indicator provided with a gravity control system controlling torques about the vertical or vertical and horizontal trunnion axes the precessional motion relatively to the meridian is aperiodic and the rate of increase of tilt of the rotor axis due to the earth's rotation is balanced by an equal and opposite precession. In apparatus of the kind described in Specification 166,570, in which the gravitational control system consists of a pivoted level connected to the gyroscope by springs, damping being effected by air jets from the rotor casing, the spring control is preferably dispensed with. The pivoted block used in the invention of Specification 166,570 for obtaining a couple about the vertical is used for indicating the deviation from the meridian.

Abstract: 567,645. Valves. TURNER MANU. FACTURING CO., Ltd., and GROVES, W. R. Nov. 6, 1942, No. 15671. [Class 135] A relief valve for byepassing the delivery of a pump feeding an accumulator when the accumulator pressure exceeds a predetermined maximum, is adapted to open and close with a snap action. The relief valve 7 cooperates with a seat 8 and is integral with a small piston 6 of smaller area than the valve subject to the pressure in the outlet 3 transmitted through a passage 29. The valve is normally held to its seat by a spring 13 engaging an abutment 12 having a partspherical boss engaging a tapered bore in a large piston 10 engaging a hollow valve stem provided with ports 30 and 25. A bore 15 in the piston 10 is formed with a seat for a non- return valve 17 lightly loaded by a spring 20. Normally, fluid from an inlet 2 passes through a groove 31 and spring-loaded non-return valve 26 to the outlet 3. When the pressure reaches the desired maximum it acts on the piston 6 to crack open the valve 7, fluid then passes through ports 30, tubular stem 9 and ports 25 to act on the upper surface of the piston 10 to open the valve widely. Fluid then opens the valve 17 and passes through ports 21, 22 to the relief outlet 4. A bleed port 23 is formed in the valve 17 to prevent leakage past the main valve, building up a pressure above the piston 10. According to the Provisional Specification, the valve 7 may be replaced by a piston valve and the seating for the valve 17 is formed on the underside of the piston 10.
