Patent GB-915948-A (GB)
Title: Liquid level control means
Inventor: MUELLER RICHARD JOHN
IPC: G05D9/12
Filed: 1960-10-19
Abstract: 915,948. Automatic liquid level control. AUTOMATIC CANTEEN CO. OF AMERICA. Oct. 19, 1960, No. 35824/60. Class 38 (4). In a system for automatically controlling the level of a liquid in a tank, a relay switch is actuated by the operation of a relay winding to effect the supply of liquid to the tank and a shunt circuit, including an electrode disposed in the tank, is connected across the relay winding and is opened to render the winding operable by the liquid breaking contact with the electrode when the liquid level falls below the lower end of the electrode. As shown, a tank 1 of a coffee vending machine has an insulating lid 17 through which projects electrodes 19, 16. A delivery pipe 26 protrudes into an opening 27 in the lid and the admission of liquid is controlled by a solenoid-operated valve 23 energized from a supply 3, 4 through contacts 13 of a relay 10. The relay is energized through an isolating transformer 2 and a capacitor 7 arranged to form a series resonant circuit with a relay coil 9. When the level of the liquid is below electrode 19, the relay 10 is energized so that contacts 12 isolate the electrode 19 and contacts 13 energize the valve 23 to allow liquid to flow to the tank. When the liquid touches the electrode 16 the relay coil 9 is short-circuited by the liquid, contacts 13 being opened to close valves 23 and contacts 12 closed to connect the electrode 19 to the relay coil circuit. The electrode 19 maintains the short-circuit across the relay coil until the liquid level falls below the electrode. The relay is then energized and the relay 10 and valve 23 are cycled to maintain the level of liquid between the limits set by the electrodes. In a modification, the electrode 16 is dispensed with and the valve 23 is energized through contacts 13 for a period determined by a motor-driven time-switch. After one rotation a switch is closed by a projection on a drum to short-circuit the relay 9. The time-switch is reset by the over-run of the motor rotating the projection past the switch.

Abstract: 847,967. Coating by dipping. STAHLUND WALZWERKE RASSELSTEIN/ ANDERNACH A. G. Nov. 21, 1957 [Nov. 22, 1956], No. 36270/57. Class 82(2) Metal strip, e.g. steel strip is coated with metal such as tin, zinc or aluminium by a hot dipping process that comprises passing the strip finally through a flux, then through a melt of the coating metal and then between crushing surfaces at a location out of contact with the melt in the presence of an inert protective gas, there being continuously supplied to the said surfaces a cleaning and lubricating agent which serves to remove metal compounds formed on the coated strip. In the apparatus shown in the Figure strip is fed downwards past heating devices 5, through a flux 6 and into the coating metal melt 2 flux carried into the metal bath being brushed off by brushes 7. The strip passes round guide roller 4 and then vertically up the other limb of the container 1 to the crushing rolls 8. Before reaching the rolls the strip passes from the melt through conduit 15 to which an inert gas such as nitrogen is supplied. The cleaning and lubricating agent is supplied to the surfaces of the rolls in finely divided form from perforated tubes 11 and 12. This agent may be hydrogen chloride, hydrogen chloride and ammonia, tallow and sal ammoniac or killed spirits. The roll surfaces may be metal repellant, e.g. of silicone rubber or polished metal. The smoothness of surface of one roll may differ from that of the other so that different thicknesses of coating metal are formed on the two sides of the strip. In a modification (Fig. 2, not shown) the cleaning agent is supplied into the duct 15 near the top thereof. The use of other cleaning agents such as oils, waxes, lacquers or water is also referred to.

Abstract: 392,482. Fountain pens. KUTTER, L., 4, Johann Hoffmannplatz, Vienna. Dec. 22, 1932, No. 36297. Convention date, Dec. 28, 1931. Addition to 312,180, [Class 146 (iii), Writing-appliances &c.], and 364,436. [Class 146 (iii).] In a fountain pen having a nib-retracting arrangement according to the parent Specifications, the nose 25 of the bent leaf-spring 23 controlling the opening and closing of the flap 15 co-operates with a notch 32 in the inner tube 5, and the inner tube is adapted to be secured automatically in the retracted position in order to lock the flap in closed position. The notch is continued by an axial depression in the tube 5 so as to provide accommodation for the nose 25 when the nib is projected. Protuberances 34 are formed on spring strips 35 cut from the tube 5 and co-operate with a projection 31 in the outer tube. The projection 31 is preferably formed by a ring secured in place in the barrel in such a position as to close the end of the groove 4 in which the guide-pin 13 slides. In closing the pen, the flap remains open until the nose 25 is engaged by the notch 32, when the spring is carried along by the tube. When the flap is closed, the protuberances 34 snap behind the projection 31 and cause a slight lengthening of the spring to hold the flap in place. For use, the tube 5 is pushed into the outer tube, the strips 35 permitting the protuberances to pass the projection 31 and then acting frictionally to retain the tubes in an adjusted position.
