Title: A method of, and equipment for, controlling the supply of liquid fuel to a storage tank
Inventor: WEBBER JOHN STANLEY
IPC: F16K31/18
Filed: 1961-04-18
Abstract: 1,035,801. Filling tanks. J. S. WEBBER Ltd. July 17, 1962 [April 18, 1961; Aug. 9, 1961], Nos. 13894/61 and 28741/61. Heading B8T. Liquid fuel is fed into an empty storage tank at a rate less than a predetermined value until the liquid level reaches a predetermined safe level whereupon the rate is increased. In one form of apparatus a valve in a supply duct is manually adjusted to give the initial flow rate; a motor is then geared to the valve and is automatically switched on when the tank liquid level reaches the safe level to fully open the valve. The motor control system includes a cam 7, Fig. 2 (not shown), on the arm 5 of a float 6 which operates a microswitch 11 when the liquid reaches the desired level in the tank 1. When the valve reaches the fully open position a switch is automatically operated by the valve to stop the motor. Alternatively a valve 25, Fig. 4 (not shown), in the fluid supply duct 2 comprises a slidable shutter 28 with a " saferate " aperture 29 and a " full bore " aperture 30 which are aligned with the duct dependent on the position of a piston 32 in the cylinder 33 of a fluid motor. The opposite ends of the cylinder are supplied with pressure fluid depending on the position of a valve member 37 of a control valve 26 operated by a tank float 45. The " safe rate " aperture 29 is effective until the fuel reaches a predetermined level whereupon the aperture 30 is brought into alignment with the duct. In the system of Figs. 5-7, not shown, an iris diaphragm valve 50 in the supply duct is operable manually and also by an electric motor 53 which rotates in either direction to open or close the valve depending on the position of an arm 68, of a balanced relay having control coils 69, 70. The attraction of the coil 70 is dependent on the pressure difference of the fuel between points 59 and 60 of the duet 2 and also on the size of the valve aperture; the attraction of the coil 6 is increased when a normally open switch 74 is closed consequent upon the fuel reaching a predetermined level. Initially the arm 68 is drawn towards the coil 69 whereupon the motor opens the valve to permit a safe flow rate; the motor will then stop or move in one direction or the other to vary the valve opening, depending on the flow rate. When the switch 74 is closed the valve is more fully opened to permit a full flow rate.

Title: Magnetic data storage device and a method of producing such a device
IPC: H01B1/00
Filed: 1961-04-19
Abstract: A bi-stable magnetic film core is made by electroplating a nickel-iron coating on to a conductive non-magnetic surface formed on a non-magnetic base member by producing a metal salt in situ thereon and immersing the conductive surface in an aged solution of sodium or potassium mercurous cyanide.  A silver coating is formed on a flat, rod-like or filamentary base member of glass, quartz, synthetic resin or a copper beryllium alloy by cleaning, sensitizing by immersion in stannous chloride solution and, after rinsing, spraying on silver solution and a silver spray reducer using nitrogen gas.  The base is moved through the spray zone several times at increasing speeds. After rinsing, the silver coated base is immersed for a few seconds in an aged solution of sodium or potassium mercurous cyanide so that an alloy of silver and mercury is formed on the surface of the silver coating. A thin film of nickel and iron (97% \sB2%) is then electroplated on to the silver coating and a cover of urethane resin is applied.  A filament, rod or other base on which the conducting base is formed may be passed with about 3 inches exposed through the electrolyte at about 5 inch per minute, the plating current being from 12-25 milliamps.  A tubular or spiral anode may be used. The electrolyte may consist of 290 grams of Fe Cl2.4H2O, 12 grams of Ni Cl2.6H2O and 238 grams of Ca Cl2 per litre of water solution with addition of dilute H Cl to bring the pH value to 1.00\sB0.05.
