Title: Process for refining, degasifying and correcting the composition of light metals and light metal alloys under a salt bath
IPC: F27B14/00
Filed: 1947-12-24
Abstract: 646,587. Refining metals and alloys. STERENTAL, V. Dec. 24, 1947, No. 34218. Convention date, Dec. 12, 1942. [Class 82(i)] In a process for refining, degasifying and correcting the composition of molten light metals and alloys before and while ladling them, a furnace is employed which has two chambers communicating at their bottom, the larger. chamber serving as a container and the smaller chamber serving for transfer and ladling, the bottom of the smaller chamber being at a lower level than the bottom of the larger chamber at the end of the ladling operation. The furnace is first charged with a protecting and refining salt bath having a lower specific weight and a lower melting temperature than the metal or alloy to be treated. A stream of molten metal or alloy is passed across the salt bath before reaching the bottom of the furnace and is refined and degasified and its composition corrected while being maintained molten. The temperature of the melt is adjusted to be suitable for the ladling operation, the molten salt covering the metal in the smaller chamber being removed and, if desired, poured into the larger chamber. Suitable containers are shown in the drawings, Fig. 1 showing a refractory lined crucible and Fig. 2 a tilting crucible. In the crucible shown in Fig. 2 the larger chamber 1 is provided with a recess 5 which receives all the metallic bath when this recess is in its lowermost position. The Specification as open for inspection under Sect. 91 comprises also a crucible having a ladling chamber of tubular form which is enclosed by the crucible and with which it communicates through its open bottom which ends a short distance from the bottom of a well in the crucible. This subject-matter does not appear in the Specification as accepted.

Abstract: 865,223. Oscillating vane motors and pumps. GIRLING Ltd. Jan. 27, 1960, [Oct. 28, 1958], No. 34420/58. Class 110 (2). In an hydraulic vane device the surface in the chamber with which the outer edge of the vane, 23, cooperates comprises a separate arcuate member, 27, mounted in the housing and concentric about the vane shaft 18. A closed sectorshaped chamber 16, Fig. 3, comprises base member 12 and cover 13 co-operating with a hollow body 10 through steel gaskets 14 incorporating a rubber sealing member 15. A shaft 18 mounted in spaced bushes 19, 20 in the sleeve 17 having an oil seal 21 provides for angular movement and transmits power from the actuator through the arm 22. A vane 23 has at its inner end a hollow boss 24 to receive the splined upper end of the shaft 18 and a peripheral seal 26 of rubber or the like for cooperation with the gaskets 14 and the arcuate member 27, which consists of a metal strip having its centre of curvature coinciding with the axis of shaft 18. The ends of member 27 are held in radial slots or grooves in cylindrical rods 28 maintained in recesses 29 in the housing of such diameters that the clearance 30 between the member 27 and the housing communicates with the chamber 16, but fluid flow between the vane separated compartments is prevented by the shoe 31. To provide for fine adjustment in the clearance between the vane and member 27, the shoe 31 is locked by a screw-threaded pin 32. In a modification, the rods 35 are a close fit in bores in the housing, Fig. 4 (not shown), so that the shoe 31 is omitted and a set-pin 36 engages directly with the member 27, this embodiment being preferred under conditions when it gives less distortion of the member 27. Specification 836,669 is referred to.

Title: Electrical inverter systems employing semiconductor devices
IPC: H02M7/5383
Filed: 1958-10-30
Abstract: 869,585. Transistor inverter circuits. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 30, 1958 [Nov. 5, 1957], No. 34822/58. Class 40(6) An inverter comprises a transformer input winding in series with a transistor and a capacitor and having a feedback winding arranged to render the transistor alternately conducting and non conducting and thus to energize the input winding, alternately in opposite directions, the capacitor being charged through the input winding and discharged through the winding and the load and serving to initiate the reversal of the charging of the input winding. The Figure shows an arrangement comprising two transistors which become conductive alternately. When transistor 37 conducts an increasing current flows from the battery through transformer winding 23 and the transistor 37 to induce a voltage in load 9. In addition current flows from the battery through winding 25 and a winding 57 to charge capacitor 75 and this induces a voltage in winding 59 maintaining transistor 37 conducting and transistor 39 cut off. When capacitor 75 is fully charged the voltage developed in winding 57 falls to zero so cutting off transistor 37. Capacitor 75 then commences to discharge through winding 57 inducing a voltage in a winding 61 causing transistor 39 to conduct. The discharge of the capacitor is followed by a charging period, at the termination of which the condition of the transistors again reverses. The frequency is substantially independent of the supply voltage since it depends mainly upon the capitance of capacitor 75 and the resistance of the transistor when conducting. The frequency may be varied by varying the value of the capacitor 75.

Mercury produced collects in 14, which acts as a storage reservoir and reserve pump supply, and is returned to 1 by pipe 17. The pipe may be outside the apparatus, and the pump need not be in the substantially axial position shown.

Abstract: 339,456. Pintsch Akt.-Ges., J. Dec. 8, 1928, [Convention date]. Drawings to Specification. Signal-failure tell-tale apparatus.-In order to allow the distant supervision of unmanned aerial and marine signalling points or stations, the signal equipment is associated with a low-powered wireless transmitter the radiation from which indicates the proper functioning, or break down, of the main signalling-apparatus. For instance in the case of a light-buoy or similar optical signal, the emitted ray falls upon a selenium cell inserted in the grid circuit of a local valve-oscillator and so ensures " tell-tale " radiation. With a gasoperated signal, failure of the gas current affects a diaphragm in the circuit of the valve-oscillator so as to interrupt or modify the nature of the wireless radiation. A similar arrangement is applicable to acoustic or electrically-operated submarine or other signalling-equipment. When the main signal is operated by compressed air, failure of the air supply may close a normallyopen switch, and thus initiate the wireless " tell-tale " signal.
