Title: Improvements in hydraulic supporting or lifting devices
IPC: E21D15/45
Filed: 1955-01-03
Abstract: 780,345. Hydraulic pit props. EISENWERK WANHEIM GES. Jan. 3,1955 [Jan. 16, 1954], No. 128/55. Class 20(2) [Also in Groups XXVIII and XXX] A hydraulic pit prop has a built in piston pump which comprises a low pressure piston 17 sliding in a cylinder 1 formed in the pressure piston 2 which is connected to the upper element 3 of the prop and which operates in a cylinder formed in the lower element 6. The  piston 17 is adapted to be carried along by a plate 19 slidable on a hollow piston rod 4 and loaded by a spring 20 supported at the other end by a member 21 secured to the rod 4. A high pressure piston 15 is slidable in a bore 16 formed in the piston 17. The piston rod 4 passes through a packing 9 loaded by a spring 22 which functions as an outlet valve from the cylinder 1. Secured to the opposite end of the rod 4 is a compensating piston 25 operating in a chamber 8 which also contains an overload valve 26 which may also be manually operated by a shaft 27. Initial actuation of the rod 4 by a manually actuated shaft 12 operates the low pressure piston 17 through the spring 20 to extend the device. When the spring 20 can no longer move the piston 17. against the pressure in the chamber 5, the high pressure piston 15 operates to build up the final pressure. The pressure in the chamber 8 due to its connection through the hollow rod 4 to the chamber 5 acts on the piston 25 to assist the pumping stroke of the rod 4. Driving devices operated by compressed air may be used in place of a hand crank.

Filed: 1959-01-02
Abstract: An electrically-conducting, gas-impermeable, semi-permeable membrane is prepared by impregnating a sheet material of synthetic resin fibres insoluble in water a solution of a polyamide resin in a water-soluble solvent and then leaching the solvent from the impregnated sheet material by washing with water.  The sheet material may be stranded, woven or felted, and may be of nylon, acrylonitrile copolymer, e.g. with vinylidene chloride, or vinylidene chloridevinyl chloride copolymer.  The impregnation may be by spraying or dipping. The watersoluble solvent may be dimethylformamide, dimethyl sulphoxide, ethylene carbonate, methyl alcohol, ethyl alcohol, propylene carbonate, butyrolactone, isopropyl alcohol or N-methyl-2-pyrrolidone.  The products may be used as battery separators.  The impregnating solution may also include an ionexchange synthetic resin, in which event the product can be used as a separator membrane in an electrolytic cell, or an antiseptic salt, such as a silver cellulosate or silver polyvinylate, in which event the product is an antiseptic fabric resistant to laundering.

Abstract: 450,149. Imitation fires. COLLINS, G. H., and COLLINS, H. F., Premier Works, Keeley Street, Birmingham. Jan. 4, 1935, No. 372. [Class 126] In an imitation fire comprising imitation fuel 10 and a surface or screen 14 on which flame or smoke effects are produced by light from a flicker device 11, an additional light source 21 is provided beneath or behind the fuel to illuminate it by a steady light, and means 16 virtually completely hidden by the fuel is provided for preventing light from the flicker device passing to the lower parts of the fuel which thus present a steady glowing effect. In the construction shown, the fire as a whole, the flicker device 11, and the screen 14, are similar to those described in Specifications 404,302, 426,887, and 427,412, the screen 14 being translucent and having a matt outer surface on which the flame-like images are formed. The means for preventing light from the flicker device from reaching the lower part of the fuel comprises a metal sheet 16 secured to the lower edge of the screen 14 and having an opening 20 through which the lamp 21 projects to provide the steady glow. The front of the sheet is reflecting, and a bent portion 24 at one or both sides of the lamp reflects the light upwardly. Alternatively, the screen 14 may extend substantially to the base of the fire, the lower part being rendered reflecting and substantially opaque by silvering, and replacing the sheet 16. To prevent reflection of light passing from the lamp 21 through the screen 14 on to the flicker device 11, the domed top of the device may bo darkened by painting, oxidizing, or otherwise.

Abstract: 564,388. Electric soldering irons. ROCHMANN, A. I. Jan. 9, 1943, No. 461. [Class 39 (iii)] A copper bit holder contains the forward end of a flat heating coil 19 folded midway of its length and tapped at this point to a terminal 13. An insulating strip 26 lies outside the folded element, and strips 23, 24 within the fold. The tube 1 enclosing the heating coil carries a two-part insulating handle 6 enclosing a terminal block 10 carrying three terminals 11, 12, 13, and a spring switch blade 15 controlled by the user by means of which one half of the heating resistance may be shortcircuited to secure more rapid heating. The handle also contains a mercury switch 28 which is adapted to cut off the current when the iron is laid on its side. An alternative form of heating resistance comprises a steatite tube with separate cavities for the coiled resistance. The tube may be split to provide an air gap between those parts of the resistance having a high voltage drop, and the gap may be filled with mica. The shunt wire may pass through a third cavity.

Abstract: 1480292 Open-end spinner; stopping and piecing-up K TSUBATA and H HIRAI 1 Jan 1975 [30 Sept 1974-4 Oct 1974] 508/75 Heading DID  During the stopping of an open-end spinner to provide a yarn and suitable for piecing-up, the ratio of yarn and withdrawal speed to decreasing rotor speed is kept constant. In a spinner having open-end spinning units; Fig. 6, during decelleration of rotors 204, fibre feed and combing rollers are stopped suddenly and simultaneously. The package-driving drums on shaft 227 are then stopped suddenly by braked clutch 229, and simultaneously reversible clutch 230 is actuated to move the common yarn deflector rod 232 having guides 231. Guides 231 withdraw yarn from the rotors until microswitch 236 disengages clutch 230. Variable transmission 241, 242 ensures that the yarn units are withdrdawn at a speed to preserve the withdrawal speed to rotor speed ratio. An air suction unit of the rotor is then switched off. To restart spinning, the suction unit is first switched on, and then driving rotor acceleration the combing roller is unbraked and rotated and rod 232 moved back to piece-up the yarn ends, the rod being moved at a rate such that the suction currents maintain the ends taut. Each combing roller, Fig. 5, may be driven by common shaft 122 and braked by brake lever 108 pivoted by common cam shaft 119. Alternatively, Fig. 3, pivotal brake lever 8 is held off by solenoid 12, and is connected by lever 15, preferably a leaf spring, to move yarn gripper 16 against stop 17 to maintain the yarn and in the twist tube.
