Abstract: 1308678 Continuous electrolytic treatment of wire SOC INDUSTRIELLE HONEYWELL BULL 3 April 1970 [3 April 1969] 16026/70 Heading C7B [Also in Divisions B3 and H1] In a process for continuously coating an elongated, conductive core 1 with a layer, preferably of thin magnetic material, the core is supplied to the coating means with substantially zero tension and is pulled therefrom when coated. A copperberyllium wire is unwound from a drum 2 by an electric motor 5 and passes between contacts 16, 17. An electrical potential is applied to the core and when it touches either of contacts 16 or 17 the speed of the motor 5 will be increased or decreased respectively. The core enters an electrolytic degreasing bath in a tank 18 which contains a mixture of sodium carbonate and sodium bicarbonate at 60C, the current density being about 20 amp/sq. decimeter. After passing through a rinsing tank 19 the core enters an electrolytic deoxidation bath in a tank 20 containing hydrochloric acid of one tenth normality at ambient temperature. The core is again rinsed in a tank 21 and then electrolytically polished in a tank 22 containing 85% orthophosphoric acid at 17C with a current density of 300 mA/sq.cm. The core then passes through an electrolytic tank 23 containing 30% sulphuric acid at 50C. and it may then pass through a further tank (not shown) containing 30% nitric acid at 17C. prior to being rinsed in a tank 24. The core is then electrolytically copper plated in tanks 25, 26 which each contain a bath of 250 grams per litre of cuprous sulphate mixed with sulphuric acid. The baths are maintained at less than 40C. with a current density of some tens of mA/sq.cm. A layer of gold may also be deposited on the copper. The wire then passes through a tank 27 containing an acid solution and then through an electrolytic tank 28 containing a nickel iron electrolyte, which deposits an alloy thereof comprising about 18% iron. The wire is annealed in an oven 29, if necessary in a magnetic field. Rollers 9, 10 push the wire into a device 11 for measuring its physical properties, the device 11 also controlling a cutter 12 for cutting out defective wire.

Title: Improvements in or relating to hydraulic control valves
IPC: G05D23/185
Filed: 1943-10-04
Abstract: 576,478. Fluid-pressure servomotorcontrol systems. INTEGRAL, Ltd., (formerly INTEGRAL AUXILIARY EQUIPMENT, Ltd.), and WORLIDGE, R. F. Oct. 4, 1943, No. 16242. [Class 135] The flow of pressure liquid to an hydraulically operated device is controlled by a valve which is moved by fluid pressure, and the application of such fluid pressure to the valve is determined by a thermostatic element actuated in part by a temperature sensitive element situated remotely from the valve and in part by the variations in the position of the hydraulically operated device. The invention is shown applied to apparatus controlling the temperature of'the cooling fluid for an aero engine by. actuation of a radiator shutter by means of an hydraulic jack connected to port 4. Pressure fluid enters at 2 and can creep past the piston valve 1 into a chamber 9 where pressure is built up until the resistance of a spring 7 acting on the valve 1 is overcome. The .valve then moves to the left to allow pressure fluid to flow to the jack to open the radiator shutter. When the valve moves to the right, the port 4 is connected to drain 8. The ends of the left hand land of valve 1 are chamfered to allow a gradual opening of the valve to prevent shocks. The build up of pressure in chamber 9 is determined by a leak-off needle valve 12 which is connected to and under the control of a Bourdon tube 15 floating in oil and connected by a capillary tube 16 to a temperature feeler consisting of a bulb partially filled with mercury. A follow-up device for resetting the datum position of the Bourdon tube after each operation comprises a wire connected at one end to the shutter mechanism and, at the other end, to a pulley 23. The latter drives a spindle 27 through interengaging pins 25 and a disc 26 and the spindle is screw-threaded into a sleeve 28 so that, as the pulley is rotated, the spindle 27 advances and pushes on the end 29 of the Bourdon tube, and the other end of the tube alters the setting of leak off valve 12. The pulley is loaded by a spring 31 the tension of which can be adjusted by a screw 32.

Abstract: 1,260,623. Wrenches. COOPER INDUSTRIES Inc. 8 April, 1970, No. 16721/70. Heading B3N. A power-driven wrench has a housing 22 with a rotatable socket 39 mounted at one end, the socket having a slot 37 which can be aligned with a slot 44 in the housing; a motor is housed in housing 31 and is drivingly connected to the socket by a drive train in which there is an arrangement whereby when the motor is stopped after a fastening operation and the socket is moved off the fastener, the socket is caused to rotate in the direction of fastening until the two slots are aligned so that the wrench can be removed from a tube to which the fastener is attached. The motor drives a spindle 55 which drives a main drive gear 57 via a drive pin 59 and a lug (62), Fig. 3 (not shown) on the gear 57. A clock spring 67 also interconnects spindle 55 and gear 57 and biases pin 59 into engagement with the non- driving side of the lug 62. Thus, when the motor is started the clock spring 67 is wound up. However, there is no movement of the drive train due to a catch 78 fixed to gear 72 abutting a detent spring 76. This spring does not affect rotation of the socket 39 once pin 59 drivingly engages the lug (62). After a fastening operation, when the motor is stopped the slot 37 may not be aligned with slot 44. But when the socket is moved off the fastener the clock spring causes the main drive gear 57 and thus socket 39 to rotate in the same direction as for fastening until catch 78 abuts detent spring 76. In such a position the two slots are aligned.
