Title: Improvements in or relating to weighing balances
IPC: G01G23/18
Filed: 1937-12-24
Abstract: 508,051. Weighing-apparatus. SEITZWERKE GES. Dec. 24, 1937, No. 35830. Convention date, Dec. 24, 1936. [Class 143] In a weighing-balance wherein the vibrations of the balance repeatedly interrupt the circuit of a solenoid or relay to prevent actuation of the pressure device of the printing mechanism or the locking device of the indicator, the circuit is provided with a delay control devoid of inertia, for example a gaseous discharge relay, in association with a condenser so that the pressure or locking device is only operated after the balance has come to rest. As shown, the damping device 1 of the balance vibrates a contact tongue 5, carried by a lever 3, between two stops 6, 7. The stop 6 and the lever 3 are arranged in circuit with a condenser 12, control electrode Z of a gaseous discharge relay 14 and potentiometer 15. When the balance comes to rest the contact tongue 5 ceases to engage the contact 6, and the condenser 12 charges, thereby causing a flow of current through the gaseous discharge relay and through a relay 18 to close contacts 19, 20. A coil 21 is thus energized to lock a disc 25 on the indicator and to close contacts 26, 27 causing the actuation of the pressure mechanism 29 of the printing device. For adjusting the delay in operation other condensers 11, 13 of different capacities may be selectively switched in. In a modification, the stops 6, 7 are arranged on a drag pendulum so that a rubbing action takes place on the contact 5 and keeps the contact surfaces clean.

Abstract: 786,467. Universal joints. GENERAL MOTORS CORPORATION. Dec. 15, 1955 [Dec. 21, 1954], No. 36008/55. Class 80 (2). A coupling adapted to allow of slight angular misalignment and to transmit axial thrust is particularly applicable to the connection of the turbine rotor shaft 26 of a gas turbine engine to the compressor shaft 18. The coupling comprises a sleeve 40 in splined connection at 42 and 44 with the shafts 18 and 26 respectively for the transmission of torque and a series of interfitting flexible spring discs 66, 68, 70, 72 and 74 located between sleeves 46 and 62 for transmitting axial thrust. The spring discs interfit by means of annular grooves and flanges and the end discs engage radial flanges 64 and 96 on the sleeves 62 and 46, these sleeves being secured to shafts 26 and 18 respectively. The arrangement of spring discs prevent relative lateral movement and consequently relative axial displacement of the two shafts, but allows a slight angular displacement provided by the flexing of the discs.

Abstract: 1483051 Tubular pressure filter STEETLEY (MFG) Ltd 30 July 1974 [30 July 1973] 36074/ 73 Heading BID A pressure filtration apparatus comprises a filter housing 1 and within the housing a filter cloth covering a hollow e.g. cylindrical or conical foraminous support 2 having ducts 3, and a first flexible membrane 16 (e.g. of rubber) which is pressurised by a first pressure liquid from lines 12 and 13. A second pressure liquid is pumped through a line 58 to apply pressure on the outside of hollow barrier membrane 51 of unit 57, which membrane pressurises the first pressurised liquid carried internally of cylindrical support 50 and forces first pressure liquid through tubes 12 and 13 to the outside of first flexible membrane 16. Unseparated material (magnesium hydroxide slurry) enters through 8 and space 39, displaces rubber ring 42 (which acts as a one way valve), fills space between membrane 16 and hollow support 2, and is pressed therein. Solid is ejected through hinged bottom outlet when catch 32 is operated by hydraulic ram 36, and member 19 is swung downwardly on pivot 28 by hydraulic ram 29. Air is blown inside hollow support 2 through line 7 (after liquid has been withdrawn through tube 9) to release the solid from the filter cloth. In Fig. 2 (not shown) unit 57 may be absent and replaced by a cylinder in which the barrier membrane is replaced by a piston having each of the pressure fluids on respective sides. The first pressure liquid may be glycerine and the second lubricating oil.

Abstract: 381,036. Controlling change-speed gearing ; locking sliding members. FIAT SOC. ANON., 250, Via Nizza, Turin, Italy. Dec. 31, 1931, No. 36082. Convention date, Nov. 3. [Classes 80 (ii) and 80 (iii).] Change-gear control mechanism comprises a striker 4, Fig. 1, rigid with a sleeve 5 slidable on a fixed guide-rod 3 and adapted to be locked thereto automatically and to be released by the first striking movement of a control lever 8. The sleeve 5, two of which are shown selectively operable, has a gap 6, into engagement with which a ball end 7 of the lever 8 can be brought. Elbow levers 12, 12<1> shaped as shown in Figs. 4 and 5, are pivoted at 13, Fig. 2, on the sleeve 5 and biased by coil springs 15, Fig. 1, so that bent-over ends 11, 11<1> are pressed against the rod 3. The other ends 14, 14<1> of the levers 12, 12<1> project over the gap 6 so as to embrace the lever end 7. In the neutral position shown, a locking end 11 of one lever 12 engages a cam recess 10 in the rod 3, while the end 11<1> of the other lever 12<1> is pressed against the rod, so as to effect a frictional lock of the sleeve 5 to the rod 3. When the control lever end 7 is moved upwards of Fig. 2, the lock lever end 11 rides out of the recess 10 and along the rod 3 until it snaps into a locking-recess 9, a change element (not shown) having been moved to gear position by the fork 4. The control lever end 7, on being moved downwards, first presses on the elbow 14 so as to lift the lock end 11 of the lever 12 out of the recess 9. The sleeve 5 is then carried downwards until the lock end 11<1> of the lever 12<1> snaps into a locking-recess 9<1> with the change element in a fresh gear position. Specification 289,788, [Class 80 (ii), Gearing, Variable-speed &c.], is referred to.

Abstract: 1,144,388. Alkali metal-halogen rechargeable fuel cells. GENERAL MOTORS CORP. 10 Aug., 1967 [5 Oct., 1966], No. 36791/67. Heading H1B. [Also in Division C7] An alkali metal, e.g. Li. Na, or K, is electrolytically produced from the fused halide salt in an electrochemical cell, particularly in a secondary type fuel cell being recharged, using a carbon anode, wherein free alkali metal is introduced into the electrolyte (additional to that dissolved from the cathode on to which it is deposited), preferably by electrodepositing the alkali metal on to the anode during intermittent reverse pulses of current, thereby achieving current densities of up to 15 A./cm.<SP>2</SP> and permitting high recharge rates. In a Li/LiC1/C1 2  fuel cell, the intermittent reverse pulse causes erosion of the graphite anode surface with formation of lithium carbide from the deposited Li which dissolves in the electrolyte. Preferably a pulse generator powered switch is used to reverse the current for appropriate small time intervals during continuous charge, e.g. a reverse pulse of 2 m.secs. or 10 m.secs. every 100 m.secs.
