Title: Electromagnetic switch for direct or alternating current, with high-remanence magnetic system
IPC: H01H50/16
Filed: 1954-07-27
Abstract: 752,870. Electrically-released switches. SCHRACK ELEKTRIZITATS-AKT.-GES. E. July 27, 1954 [Aug 4, 1953; March 13, 1954], No..21933/54. Class 38(5) In an electromagnetic switch which is closed by a short current impulse, remains closed owing to its remanence and is opened when demagnetized by another impulse, the magnetizing current is interrupted a short time after the full engagement of' the magnet armature with the iron core by means of a time delay device. A magnet carrying an exciting coil 2 has an armature 3 rigidly connected with a bridge 4 carrying contact bars 6, 13. The exciting circuit 8 connected between T, O, is divided into parallel loops 8<SP>1</SP>, 8", the former containing closing contact 9, normally closed contact 11 controlled by timedelay device 10 and a section 2<SP>1</SP> of the coil, and the latter containing tripping contact 12, contacts 13, 14, another entire coil 2. Contact 9 closes circuit 8<SP>1</SP> and thus contacts 6, 7 and 13, 14. The movement of the armature releases time delay device 10 to open contact 11. Contact 12 completes circuit 8<SP>11</SP>, a demagnetizing current then flows through the entire coil 2 releasing armature 3 and opening contacts 6, 7 and'13, 14. Contacts 9, 12 may be replaced by a change-over switch. Alternatively the switch may be operated by a single unbiased contact, controlled for example by a thermostat or float, in which case coil section 2<SP>1</SP> and contact 11 are shunted by a capacitor for A.C. operation, or by a resistor for D.C. operation, which completes circuit 8<SP>11</SP> when contact 11 and the unbiased contact are opened (Fig. 3, not shown). The circuit may include an overload relay 18, its normally-open contact 19 being included in the circuit 8" in parallel with tipping contact 12. The timedelay device 10 (Fig. 5) may comprise a spring 24 operatively connected with armature 3 through a plunger 28 and bridge 4 and stressed against an upper abutment 29<SP>1</SP> by spring 5. When the armature is attracted the spring 24 is released to open contact 11 through lever 23 and button 22. The release of spring 24 is delayed by a pneumatic device comprising a flat air chamber having an adjustable needle valve 25 and a resilient base 27 carrying the plunger 28 the lower end of which bears on bridge 4 and has secured to it a spring abutment 29. The release of the spring 24 is controlled by the base 27, which yields downwardly in' dependence on the rate of air admission through needle valve 25. A mechanical time-delay arrangement 10<SP>11</SP> (Fig. 6) comprises a horizontal lever 33 pivoted at 32 and carrying a weight 34 and stop 35. The lever is engaged by a weak spring 36 and has an adjustable stop 37 co-operating with button 22 of contact 11. When the armature is attracted and bridge 4 moves, the lever lags behind owing to the inertia of the weight 34 which is eventually overcome by spring 36.

Title: Improvement in method and apparatus for recovering a light metal from fused salt baths
IPC: C22B26/10
Filed: 1945-08-29
Abstract: 597,562. Refining metals. McNITT, R. J. Aug. 29, 1945, No. 22225. [Class 82 (i)] [Also in Group XXXVI] A process of recovering light metal from a fused salt bath more dense than the metal to be recovered, characterised by collecting the crude hot metal in the bath, passing it upward in a duct to a body of metal in a chamber spaced from the bath, controlling the temperature of metal in the body to precipitate dissolved impurities from the crude hot metal, settling the impurities and returning them in a column of metal in another duct connecting the chamber with the bath. The body of metal may be cooled to just above the melting point of the metal, e.g. to within 15‹ C. above the said melting point. The apparatus shown in Fig. 4 comprises a hood 11 in which a pool of crude hot metal 1 is collected below the surface of the salt bath, a duct 2 through which the metal rises to a bodv of metal in the chamber 3. The chamber may comprise one or more connected receptacles 4, 5 across which the metal flows, each receptacle being connected to the hood by return ducts 6, 7 through which impurities are returned to the bath. The chamber is connected by conduit 8 with a receiver 9 for purified metal. The return duct may comprise means for impeding the flow of heat from the bath to the metal in the duct by thermal insulation, it may have a constriction to impede the upward flow of heat therein and it may be provided with means for forcing some metal and impurities downwards to the bath. Gas collected with the crude hot metal may be removed through the duct 2 or, as shown in Fig. 5, it may be removed through a separate duct 40, baffles 37 and 43 being provided to prevent the gas entering and disturbing the metal in the pool 1. The metal is passed across the pool to the duct 2 while maintained substantially free from agitation, thus effecting a preliminary purification. In order to assist purification of the metal, heating means 120 may be provided, as shown in Fig. 13, to heat metal before it overflows to the receiver, thus reducing its viscosity and assisting the settling of impurities.
