Abstract: 347,897. Protective cut-out arrangements. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 12, 1930, No. 14612. Convention date, May 13, 1929. [Class 38 (v).] Resistances the parts of which have varying heating conditions (such as the starting resistances of electric motors) are protected against harmful overheating due to overload discriminatively by several thermal relays each one of which as regards its thermal constants corressponds to a part of the resisance to be protected. In the arrangement shown in the Figure, the rotor resistance 14, 15 of an A.C. motor is protected, the resistance consists of a high-resistance portion 15 and low resistance portion 14 parts of each of which may, by their situation in the neighbourhood of heat-conducting parts of the resistance frame, have a different heat characteristic from the rest. Two thermal relays 18, 20 each with the same thermal characteristics as the covered parts of the resistances 14, 15 have their heating coils connected across these covered parts so that the power absorbed by the coils is proportional to the power dissipated in the resistance part. Similarly, thermal relays 19, 21 take care of the uncovered parts of the resistance. The contacts of all these relays (which may be remote from the resistances which they protect) are connected in series with the no-volt tripping coil 17 of the motor circuit-breaker and when any of them operates, the motor is cut off.

Abstract: 988,192. Weighing electrically; bridge circuits; potentiometric measurements. JOSEPH LUCAS (INDUSTRIES) Ltd. March 27, 1963 [April 17, 1962], No. 14777/62. Headings G1N and G1U. Apparatus for determining the weight on a weighbridge comprises a pair of strain gauges 9 at each corner of the weighing platform, each pair of gauges 9 being connected in a bridge circuit 8 with resistors which provide automatic temperature compensation, and is characterized in that the A. C. power for the bridges is obtained from atransformer 13 located at or near the weighbridge, whereby the potential drop between the transformer secondary and the bridges is minimised, and the volts drop along the power cable 12 is reduced by the turns ratio of the transformer. The combined output from the bridges is automatically balanced against the voltages tapped off from three separately fed potentiometers 20, 21, 22, the first preset to represent the unloaded weight of the weighbridge and the second to represent the unloaded weight of a container. The sensitivity of each bridge 8 is adjusted by an input rheostat 14, and the output impedances are equalised by series rheostats 15. The capacitive impedance to earth of the leads 16 may be different, resulting in different leak currents to earth. This is balanced out by adjustment of the earthing point of a potentiometer 26 across the difference amplifier 23. The bridge input and output cables 12, 16 are separate to avoid pick-up between them. Specifications 988,192, 988,194 and 988,195 are referred to.

Filed: 1931-05-19
Abstract: 375,500. Fused silica. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Devers, P. K. ; 6, Pierce Road, Lynn, Massachusetts, U.S.A.) May 19, 1931, No. 14788. Convention date, May 19, 1930. [Class 56.] A method of producing clear vitreous silica by fusing sand in a vacuum consists in producing a zone of fusion within a mass of the sand, withdrawing gases from the fusion zone, and then drawing out the fused material from the interior of the mass while excluding unfused material. The furnace for melting the sand comprises a sheet metal container 1 provided with a removable lid 2, and an electrical heating-resistance 4 consisting of graphite rods connected in series with one another. A frame 12 of angle-bars extends across the top of the container and supports a tube 13 of zirconia or similar refractory material and a graphite tube or die 14. A charge 9 of coarse sand or quartz is packed around the resistance heater 4, and this charge is surrounded by a mass of fine sand 10 which supports it and insulates it against loss of heat. A number of conduits 15, 18, 19 extend downwards into the sand and allow the removal of gases from the charge during fusion, the gases being evacuated by pumps connected to a pipe 20. Another pipe 16 has a graphite nozzle 17 which projects upwards from beneath the fusion charge to a region near the lower end of the die 14. In use, the furnace when packed with sand is sealed and the contained air is evacuated through the pipe 20, pumping being continued during the whole of the fusion period. When sufficient of the charge 9 has been melted, the top of the container is removed and the fused mass is drawn upwards through the tube 14. For this purpose, a bait 21, Fig. 3, consisting of tungsten wires 22 covered with tubes of silica, is placed within the tube 14 before fusion is started. The nozzle 17 acts as a core around which the fused silica is formed into a tube as it is drawn from the furnace.
