Title: Improvements in hydraulic operating devices for electric circuit breakers
IPC: C08J9/24
Filed: 1957-01-16
Abstract: 828,853. Automatic circuit-breakers; protective cut-out arrangements. ALLIS-CHALMERS MANUFACTURING CO. Jan. 16, 1957 [Jan. 23, 1956], No. 1639/57. Class 38 (5). A circuit-breaker has an hydraulic operating device comprising a piston 104 movable in a cylinder 106 in one direction under liquid pressure to close the circuit-breaker contacts and biased by a spring 110 in the other direction to return to its initial position and a motordriven pump 102 for supplying pressure liquid to the cylinder 106 through a pipe 108, the pressure liquid being directly returned to the pump through the same pipe upon de-energization of the motor when the piston reaches the end of a predetermined travel in the contact closing direction. To close the circuit-breaker a push-button switch 135, Fig. 5, is pressed to complete a circuit over contacts 125, 126 of a switch 121 and contacts 139, 140 of an " antipumping " relay 114 to energize the coil 116 of a relay 113 which closes its contacts 142, 143 to start the motor 101. The liquid under pressure supplied to the cylinder 106 forces up the piston 104 and piston-rod 109 which lifts a member 80. The end of a slot 83 in the member 80 moves a pin 82 on a pivoted trip bar 67 and causes the bar 67 to pivot anti-clockwise about a fixed axis 69 so that a cam surface 72 on the bar 67 acts on a roller 71 to close the circuit-breaker contacts (not shown). An arm 122 rigid with the bar 67 actuates the switch 121 as the circuit-breaker contacts close and a latch 57 engages a pin 66 on the bar 67 to maintain the circuit-breaker contacts closed. When the switch 121 is actuated it opens contacts 125, 126 and closes contacts 123, 124 to complete a circuit through contacts 144, 145 of the relay 113 to energize the coil 119 of the relay 114. This relay opens contacts 139, 140 to de-energize the coil 116 of relay 113 which opens to de-energize the motor 101. The spring 110 is then able to force the piston 104 down, returning the liquid through the pump 102 to the reservoir 103. The circuit-breaker may be closed manually by turning a handle (not shown) attached to a spindle 77 so that a cam 78 on the spindle acts on a roller 81 to raise the member 80. The operating and tripping linkage and the contact arrangement of the circuit-breaker are similar to those described in Specification 775,940.

Title: Improvements in or relating to temperature responsive devices
Inventor: FISHER WILLIAM HAWARDEN
IPC: H01H37/12
Filed: 1959-01-16
Abstract: 894,891. Thermal switches. GENERAL ELECTRIC CO. Ltd. Jan. 15, 1960 [Jan. 16, 1959], No. 1689/59. Class 38 (5). [Also in Group XIII] In a room thermostat switch, a bimetal strip 24, tapered at one end, Fig. 1 (not shown), is riveted at the other end to one end of a channelshaped carriage member 23 the other end of which has projections 22 extending from the outside of the carriage side walls to engage in notches 21 in the side walls of the channelshaped main body 1 of the device. A tapered spring 28 is secured between a cap 18 on the main body and the riveted end of the carriage 23 so that that end tends to be raised against the rounded end 37 of an adjusting screw 36 which carries a dial 38 and determines the operating temperature. The carriage is thus capable of limited movement by the rotation of the projections 22 in the notches 21 against the action of the spring 28. Riveted to the end of the bimetal 24 remote from the carriage 23 are both a knife edge 30 and an insulating plate 31 bearing a movable contact 12. The contact 12 may be carried directly by the bimetal. A U- shaped spring 32 stretches from the knife-edge 30 to an adjustable knife edge 19 to compress the bimetal 24. The head of an adjusting-screw 20 is held on to the cap 18 and the screw is threaded into an extension of the knife edge member 19. When the temperature rises, the bending moment on the bimetal 24 decreases and a snapaction break occurs so that the contact 12 drops from a fixed contact 4 to a back-stop 17 which may also include a contact. The position of the bimetal may be reversed so that the contacts close with a rise in temperature. There is a heating resistor 41 over the bimetal so that the switch may operate with light currents. The temperature range is pre-set by altering the tension in the U-spring 32 by means of the screw 20. There may be a device for locking the U-spring 32 up or down to lock the switch. The fixed contact 4 is screwed into a parttubular member 5 held by a screw on moulded insulation 2 screwed to the main body 1. A screw 8 holds supply wires in the tubular part. A terminal block, Figs. 1, 3 (not shown), is held on the insulation 2 by a screw which attaches a jumper strap, from the moving contact 12, to the block. A lead 44 from the heating resistor 41 is attached to the member 5 so that the resistor may be connected in parallel with the load by an extra wire from the neutral side of the circuit to a terminal block 42 to which the other side of the resistor is connected. The Provisional Specification describes a modified switch in which the moving contact is connected to a terminal by copper foil passing through an aperture in the main body 1 and insulation. The back stop for the contact end of the bimetal is a bridge formed on a bent-up portion of the switch body.

Abstract: 454,010. Eccentrics. GEE, W. J., 14, Queen Victoria Street, London. Jan. 18, 1935, Nos. 1795 and 29182. [Class 122 (i)] [See also Groups XXVIII and XXIX] Reciprocating pumps are actuated by eccentrics 61 mounted upon a square shaft 51. Pins 68 screwed into the eccentrics engage wedge-shaped surfaces 58, 59 on a shaft 57 axially adjustable within the shaft 51. The shaft 57 has an extension 81 secured to a sleeve 83 which is connected through a thrust bearing 87 to a screwed spindle 82. The stroke of the pump may be adjusted by the hand wheel 89 and fixed in position by the nuts 91, 92. Assuming the stroke of the pump to be nil at starting, the centrifugal force in the eccentrics will tend to move the shaft 57 axially and due to friction on the end of the spindle 82, will turn the latter and increase the stroke to a value determined by the position of the nuts 92.

Title: Improvements in or relating to hydrometallurgical production of copper
IPC: C22B15/00
Filed: 1955-01-24
Abstract: Clarified aqueous sulphate solutions containing copper and at least one of the metals nickel and cobalt are treated to recover the copper by adjusting the hydrogen ion concentration of the solution to a value less than that equivalent to a 20 per cent free sulphuric acid content, but at least 5 grams/litre in the presence of cobalt and at least 24 grams/litre in the presence of nickel, treating the adjusted solution at a temperature of above 275 DEG F. with a non-sulphidizing reducing gas, such as hydrogen or carbon monoxide or mixtures thereof, while maintaining a total pressure sufficient to prevent boiling and collecting the precipitated copper powder.  Where the initial mol ratio of copper to cobalt plus nickel exceeds one half the reduction may be initiated at a free acid less than that given above but such that the free acid content is in the required range when the said ratio decreases below about one half.  If necessary a neutralizing agent such as ammonia is added during reduction to maintain the free acid content in the required range.  Reduction is preferably performed in the range 350-425 DEG F. under a total pressure in the range 600-900 pounds/square inch.  Specification 688,574 is referred to.
