Abstract: 906,594. Electrically-released switches; contact members for switches; protective arrangements. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 4, 1960 [April 6, 1959], No. 11563/59. Class 38 (5). A short-circuiting switch, e.g. for protecting germanium or silicon diode rectifiers, has a moving bridging contact member 1 normally held in the open position against the bias of a spring 3 by the armature 19 of an electromagnet or permanent magnet 20. On the energizing of a trip coil 22, the armature is released and the spring 3 impels the contact member 1 into engagement with resiliently mounted fixed contacts 4, 5 having damping means to prevent rebound. These contacts are pivoted on spurs R, Y extending from bus-bars (not shown), have their movement in one direction limited by adjusting screws 8, 9, and are damped by an assembly comprising a spider 16 slidable on a stud 14 and biased by bow-shaped laminar spring washers 12 with an interposed disc 13. Alternatively, hydraulic damping devices may be used and the spring 3 may comprise a stack of spring washers. The switch is brought into the open position manually or by momentary over-excitation of a holding coil 21. In a three-phase arrangement the contacts may comprise a disc 1 co-operating with three fixed contacts, though a bridging contact member connected to one phase may co-operate with fixed contacts connected to the other two phases. The contacts may be silver faced and gold plated. In the arrangement in which the armature is normally held by a permanent magnet, the armature and magnet may each comprise concentric rings of magnetic and non-magnetic material. If a holding coil 21 is used, it may be energized from a battery through a series resistor having a high positive temperature coefficient. The trip coil 22 may be energized from series-connected single-phase fullwave rectifiers each connected to a current transformer in one of the phases of the protected system, Fig. 2 (not shown).

Title: Improvements in the recovery of molybdenum from mixtures of molybdenum or molybdenumcompounds with other metals or metal compounds
IPC: C22B34/34
Filed: 1930-04-14
Abstract: <PICT:0350135/III/1> Molybdenum or its compounds are recovered from mixtures thereof with other metals or compounds such as chromium, zinc or magnesium, particularly spent catalysts employed in high-pressure hydrogenations, by subjecting the mixture to oxygen or gases supplying oxygen such as nitrogen oxides or air, at temperatures not above 600 DEG  C., but preferably above 400 DEG  C. Molybdic acid is recovered from the roasted mass by treatment either with aqueous ammonia to form ammonium molybdate, which may be recovered as such or be treated with hydrochloric acid to precipitate the oxide; or with an acid, and, if desired, an oxidizing agent, say, a mixture of hydrochloric and nitric acids, to dissolve the other constituents, leaving molybdic acid; or with a solution of ammonium sulphide with or without free ammonia.  In this last form of treatment, enough reagent is employed completely to precipitate other metals as sulphides, but generally insufficient to form ammonium sulphomolybdate.  If formed, however, it may be converted into the molybdate by the addition of substances such as the oxides of zinc, cadmium, lead, tin.  Molybdenum oxide is precipitated from the solution by hydrochloric acid, care being taken to prevent redissolution by the acid.  Various sulphides such as of zinc or lead obtained may be roasted to oxides.  Prior to the initial roasting treatment, the spent catalytic mass may be treated with agents which dissolve impurities, or flocculate the same.  Agents specified are middle oil and heavy benzine.  In the roasting operation, the mass, preheated in chamber 1, is passed on small trucks through chambers 2 . . 5 in countercurrent to the oxygen-containing gas, preheated in preheater 7, so that the freshly introduced material is exposed to gases poor in oxygen. Diluting gases such as nitrogen or carbon dioxide may additionally be used.  Thus, a portion of the waste gases may be added via pipe 14.  When freed from carbon dioxide and sulphur dioxide, practically pure nitrogen may be obtained from the waste gas.  The roasted material is lixiviated in countercurrent to the extracting liquid.
