IPC: B29C48/00
Filed: 1934-01-20
Abstract: 432,110. Extrusion - apparatus for moulding and vulcanizing coverings on cables. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Kemp, A. R.; 170, Lexington Avenue, Westwood, New Jersey, U.S.A.) Jan. 20, 1934, No. 2031. Convention date, Jan. 31, 1933. [Classes 70 and 87 (ii)] [See also Group XXXVI] Heavy cables are covered with thick layers of very soft rubber compound by extrusion, and the coating vulcanised while the cable is maintained in a vertical position to prevent decentralization. Fig. 1 shows the lay-out of the plant, the cable being drawn from a reel 2 by a winch C through a straightening-device 3, extrusion-apparatus 4, steam-vulcanizing- apparatus 6, sealing-means 7 and water-spray 26, thence passing to a similar apparatus for applying a second coating which may be arranged immediately above the first apparatus or to one side as in the illustrated form. On its way to the extrusion apparatus the cable is coated preliminarily with partly depolymerized heated rubber or the like by being drawn through a tube 16<a> charged with this material. Movement of the tube develops pressure in the material. The main coating is supplied to the die 10 from the hopper 17 by the rollers 18, 19. When applying two layers in succession, the first layer may be partly vulcanized, and the process completed during the vulcanization of the superposed layer. The sealing-means to prevent escape of steam from the vulcanizing- chamber comprises a series of washers 21 which just clear the coated cable and are spaced by rubber washers 20. A typical coating composition is stated to comprise 100 parts crÛpe rubber, 1 part sulphur, 1 part zinc oxide, ¢ part stearic acid, ¢ part diphenyl guanidine, 3 parts aldehyde amine condensation product, 2 parts petrolatum base wax of high melting point and 2 parts phenyl alpha naphthylamine.

Title: Garment hanger
IPC: A47G25/02
Filed: 1971-01-15
Abstract: 1373971 Garment racks ROTAX Ltd 5 Jan 1972 [15 Jan 1971] 2072/71 Heading A4U [Also in Divisions F2 and H2] In a support for coat hangers an arm 12, slotted at 13 to receive the hangers, is mounted on a carriage which is movable vertically in a longitudinally slotted tubular guide 10 by a flexible steel band 15, one end of which is secured to the carriage and the other end wound on a drum 35 rotated by an electric motor 22 in a housing 14. The housing 14 and spaced micro-switches 18, connected by a conduit 21 for electrical leads, are mounted on the guide which has apertured ears for wall-mounting. The drum 35 is secured on a rotatable shaft 27 connected by a reduction gear chain to the rotor shaft 25 of the motor which is energized by switches to rotate in either direction to raise or lower the carriage which is arrested by de-energization of the motor. Operation of the switches which control the motor energize an electromagnet 43 so that it attracts a metal plate 38 against the action of springs 39, 40 and reduces frictional engagement between an annulus 37 of friction material, on the plate 38, and a plate 36 secured to the rotor so that the combined weight of the carriage and the arm rotates the rotor and allows the arm to descend. The carriage is locked in upper or lower limit position by contact of the arm with one of the micro-switches which de-energizes the electromagnet 43. A Bowden cable accommodated in the conduit 21 connects a pivoted lever 19 on the guide and a washer 42 separating the springs 39, 40, operation of the lever drawing the washer away from the plate 38 against the action of spring 40 to reduce the frictional force between the annulus 37 and plate 36 so that on failure of the upper micro-switch to de-energize the electromagnet the carriage and arm will move downwardly under their own weight. In modifications, the steel band 15 is replaced by a chain, the drum being replaced by a sprocket wheel, or the coat hangers are integral with the arm.

Abstract: 899,649. Controlling aircraft. SMITH & SONS (ENGLAND) Ltd., S. Dec. 15, 1960 [Jan. 20, 1960], No. 2075/60. Class 4. [Also in Group XXIX] A servo system for operating an aircraft elevator 1, under either manual or automatic control comprises a cylinder 5, connected to the elevator, housing a piston secured by a rod 6 to the air frame 7. Two control valves 8, 12 mounted on the cylinder are hydraulically connected to a two-way changeover valve 14 which connects pressure and exhaust lines a, b to one or other of the valves in accordance with the control of a solenoid 19. The control valve 8 moves the elevator in response to movements of a manually actuated control member 2, while the control valve 12 is operated to move the elevator by a signal from an automatic pilot 3. When the solenoid 19 is energized the changeover valve 14 connects the lines a, b to the valve 12 and the elevator is under the control of the automatic pilot 3. Movements of the cylinder 5 move the control member 2 through a lost motion connection formed by stops 17, 18. If at any time the control member is moved with sufficient force, a spring strut 10 in the rod 9 incorporates a switch to de-energize the solenoid so that the valve 14 moves to the position for manual control. In the event that the switch in strut 10 fails, the lost motion stops 17, 18 operate a spring arm 15 to actuate the changeover valve.

Abstract: 781,158. Grease guns. THIRION, J. Jan. 20, 1956 [May 23, 1955], No. 2082/56. Class 102(2). [Also in Group XXXIV] A grease-gun of the type wherein the grease is expelled by the action of a piston under the influence of a spring, in which the piston 2, Fig. 1, which expels the grease is loaded by the fluid liquid or gas in the enclosure to be lubricated by admission of fluid &c. via pipe 12, Fig. 2, connected to the enclosure, valve 9, and pipe 14 to the piston face opposite the face in contact with the grease. The valve 9 also controls the flow of grease from the tank through passage 10 of the valve to the outlet 7 so that when pipe 12 is connected to pipe 14 grease may flow through passage 10 and when pipe 14 is connected via the valve to pipe 15 (open to atmosphere) the flow of grease is interrupted to allow filling of the gun via the nozzle 8. A modified form of valve is shown in Fig. 10, in the gun filling position. The valve is forced open by the pressure of the grease entering opening 43 to the grease tank, pipe 14 being opened to atmosphere through pipe 15. For operation of the grease gun the valve is forced in the direction F by the spring 38, thus connecting pipe 14 to pipe 12 and allowing grease to be discharged through opening 32-32a. Specification 614,399 [Group XXXIV] is referred to.
