Title: Improvements relating to liquid-applying devices for conditioning or treating yarn and other strand materials
IPC: B65H71/00
Filed: 1945-11-29
Abstract: 600,997. Coating yarns. UNIVERSAL WINDING CO. Nov. 29, 1945, No. 32274. Convention date, Dec. 4, 1944. [Class 140] A running strand of yarn is coated with liquid by causing it to draw in continuous wiping contact against the rim of a basin across which liquid supplied to the basin is fed as an overflow, so that the yarn takes up liquid from the overflow at the rim. As shown, a yarn y, ballooning outwardly as it is drawn from a cone C, sweeps around a lip 24 of a conical wall 22 defining a circular opening in a basin 20 to which liquid is supplied by pipes 31, 33 from a tank 30 in quantity sufficient to overflow the rim 24. The overflow runs into a gutter 27 and thence through a pipe 34 into a tank 35 from which it is returned by a pump 36 to the reservoir. The moistened yarn is drawn through a tension device, which may comprise a pair of gridlike members 7 and 8 resiliently pressed against the yarn, a slub-catcher 9, around a guide 10, and wound up on a cop-tube T mounted on a winding spindle 3 driven at constant speed. The rate of supply of liquid to the basin 20 may be increased during the winding operation'to make up for the increased rate of travel of the yarn due to the increasing diameter of the wound package P. The growing package P pushes away the upper arm 16 of the traverse-frame 15 which carries the threadguide 5 and mechanism for its operation and is pivoted at 14. The resulting movement of the lower arm 17, transmitted by an adjustable link 50 to a lever 42, operates a valve 32 to increase the flow of liquid. The lengths of the levers and the link and the setting of the valve may be adjusted to suit different yarns and coating liquids. The yarn may be any strand material, natural or synthetic. The liquid applied may be an oily emulsion. Specification 558,082, [Group IX], is referred to.

Abstract: 398,678. Rotary engines. SAUVEUR, H., 12, Duisburgerstrasse, and FIEBIG, W., 4, Am Brabrink, W³lfel, both in Hanover, Germany. Nov. 21, 1932, No. 32883. Convention date, Nov. 20, 1931. [Class 110 (ii).] In a pump or engine having a gyratory piston provided with teeth, each gyrating in a recess in a casing due to the piston motion, Fig. 1, means are provided to balance the sideways thrust of the piston, due to the centre of pressure of the working fluid being eccentric to the piston centre, to prevent excessive pressure at the points of contact between piston and casing. Fig. 2 shows a pump piston 1 driven by an engine piston 2 so that balance is secured by the opposing action of the working fluid and the fluid being pumped. The piston teeth are of T-shape. In a further example the engine is split up into two stages, H.P. and L.P., with the pump piston between the stages. The opposing mean pump and engine pressures are balanced. Steam or compressed air may be used in the engine. A further arrangement describes a pump driven by an electric motor, in which two piston discs have teeth curved in different directions and may be at different radii, to secure balance. Fig. 10 illustrates a modification in which the forces are approximately balanced in a single disc. The points of contact 8, 9 lie exactly or approximately on the same diameter of the piston disc. Suction and delivery slots 27, 26 are provided. The coordinating points of contact 10, 11 on the casing lie on diameters which do not greatly differ. Rollers 24 may be eccentrically positioned in holes in the rotor disc, or a separate disc, to act as guides. Nozzle blocks may be inserted in the diaphragm of the engines. Specification 385,797 is referred to.

Patent GB-842452-A (GB)
Title: Improvements in piston pumps, more particularly for hydraulic pit props
IPC: F04B49/24
Filed: 1956-11-02
Abstract: 842,452. Hydraulic pit props. RHEINSTAHL WANHEIM G.m.b.H., No. 33523/56. Class 20(2) [Also in Group XXVIII] A reciprocating pump for extending a telescopic pit prop, comprises a low pressure piston 49 and a high pressure piston 50 and the low piston can be rendered inoperative at a predetermined pressure by a control cylinder 60 acted upon by the pressure in the pressure chamber 59 and the control cylinder 60 constitutes the inlet valve member for the low pressure piston. The low pressure piston 49 and the high pressure piston 50 are formed as a common piston body 48. The control cylinder 60 is arranged on the piston rod 45 and is urged downward by spring 62. The piston rod 45 is reciprocated by a crank 65 and on upward movement of the piston rod a driver disc 53 on the piston rod raises the piston body 48 and liquid flows from a reservoir chamber 35 through ducts 58 and 52 to the cylinders 44 and 43. On downward movement of the piston rod 45 the sealing edge 71 of the control cylinder 60 engages the top of the piston body 48 which then begins to move downwards and the liquid thus entrained in the cylinder 44 passes through ducts 58 and 52 to the cylinder 43 and the liquid in this cylinder is pumped past packing 56, acting as a non-return valve to the pressure chamber 59, which causes the piston 40 and the inner prop cylinder 36 to rise. When the head 41 of the prop engages the roof the pressure in pressure chamber 59 will rise and the control cylinder 60, containing liquid from the pressure chamber 59 through the hollow piston rod 45 and ducts 63, will move upwards against spring 62 so that the sealing edge 71 is higher than the bottom 55 of a thickened portion 46 of the piston rod. On downward movement of the piston rod the portion 46 moves the piston body 48 and seals the duct 52 from the chamber 35 so that liquid in cylinder 43 is pumped to the pressure chamber 59, but since the sealing edge 71 does not contact the body 48 liquid in the cylinder 44 passes freely back to the chamber 35 and the piston 49 is therefore ineffective. In the intermediate case where the edge 71 is just above the bottom of portion 46 the edge acts as a throttle valve, part of the liquid in the cylinder 44 passing back to the chamber 35 while the remainder passes to the cylinder 43 past packing 54 acting as a non-return valve. In a modification the control cylinder 60 is formed as an inverted cup shape member whose open end is closed by a thickened portion of the piston rod, the cup shaped member and thickened portion each carrying sealing rings to close the ducts 58 and 52 from the chamber 35. The pressure chamber 59 is provided with a relief valve 68 which can also be raised by a crank 69 to return the liquid in the pressure chamber 59 to the chamber 35 to lower the pit prop. Specification 780,345 is referred to.
