Title: Improvements in electrical contact make and break devices
IPC: H01H33/66
Filed: 1928-02-06
Abstract: 285,372. Bosch Akt.-Ges., R. Feb. 14, 1927, [Convention date]. lnterrupters, mechanical; cases; contacts.- Contacts for make-and-break switches working in a vacuum or inert gas are constructed to avoid the welding together by the arc which frequently occurs with such contacts. One or both contacts, and preferably that which is burnt away by the arc, is made in the form of a thin sheet of metal and without any metallic support, so that this contact becomes completely burnt away and holes are formed, or its surface decreases. In Fig. 1 the contacts comprise recessed thin metal sheets a, b riveted to their supports, the edge of one contact in operation being gradually burnt away so the arc metal passes to the other contact. In Fig. 3 the contacts are formed by rolling out the ends of wires e, f and are brought into contact by spring means or the resiliency of the wires. The point of contact gradually moves owing to the burning away of one contact. In Fig. 4 (not shown) a pair of such contacts are shown in a glass vessel wherein one contact is adjustable by the elasticity of the glass. Instead of the wire f being bent back, it may extend in the same direction as the wire e. The contacts may be of tungsten, molybdenum, or other metal of high temperature of vaporization.
Patent GB-607472-A (GB)
Title: Improvements relating to water heating systems
IPC: F24H9/20
Filed: 1946-02-05
Abstract: 607,472. Water heating systems. WHITAKER, A., and JESSEL, R. Feb. 5, 1946, No. 3642. [Class 64(i)] In a water - heating system with a primary source of supply of heated water, e.g. a solid fuel boiler, hot water storage tank, and an auxiliary gas operated water heater, interposed between that primary source and the delivery point of the system, and bye-passed by a water passage, a valve in the bye-pass passage is operated by a thermally responsive element influenced by the temperature of. the water in the delivery section to permit more water to bye-pass the auxiliary heater when the temperature of the water in the delivery section exceeds a pre-determined value. Water from the primary hot supply flows through pipe 14 to the auxiliary water heater coil 11 and the control chambers 18 and 20 to the outlet pipe 16. The bye-pass 14a directly connects the pipe 14 and the chamber 20 which contains a thermally responsive bellows containing ether which actuates a valve controlling the opening from the bye-pass. The gas flow to the burner 13 is controlled by a temperature actuated valve in the chamber 18 which is divided by a partition into two compartments through one of which the gas flows and through the other of which the water flows. The water compartment contains a double metallic bellows (a single may be used) which is fixed to the partition between the gas and water sections and operates the valve. If high water pressures are used in the system the bellows are not exposed directly to the water but are each connected by a tube to a strong ether phial of brass or other metal located in the water pipe. The gas supply to the burner is also controlled by the rate of water flow through the heater 11 so that when the bulk of the water is bye-passed through the pipe 14a the supply of gas to the burner 13 is cut off and the heater becomes inoperative.

Abstract: 987,452. Seals. EMILE EGGER & CO. A.G. Feb. 2, 1962 [Feb. 27, 1961], No. 4001/62. Heading F2B. [Also in Divisions F1 and H2] In a pump for solids suspended in liquids or gases (see Division F1) an oil seal ring 87, Fig. 15, engages a sleeve 88 to prevent escape of lubricant from the bearing 85, and a rotating support 89 houses a rotating seal ring 90 held in engagement with a stationary seal ring 92 by a diaphragm 93, Figs. 15 and 16. The latter comprises a diaphragm spring 94 with a flexible material such as natural or synthetic rubber, plastics and the like vulcanized or moulded about it. If the pressure in the space 96 between the impeller and the diaphragm increases during operation, the increase in pressure on the diaphragm increases the force between the seal rings 90, 92, whereby leakage can be minimized under all pressure conditions. If, however, a relief passage 83a is provided in the impeller, the pressure in the space 96 may consequently be below atmospheric pressure, so that the force between the seal rings 90, 92 tends to be insufficient. To compensate for this, the seal can be pre-loaded by means of the diaphragm spring 94.
