Abstract: 932,467. Control of A.C. motors. ZAVODY PRESNEHO STROJIRENSTVI GOTTWALDOV NARODNI PODNIK. Nov. 14, 1960 [Dec. 19, 1959], No. 38954/60. Class 38 (3).  [Also in Group XXIV] For varying the speed of a machine tool, an induction motor with changeable poles or electromagnetic couplings 8, 8<SP>1</SP> are controlled either according to a set programme or by push button following a pre-selecting operation. As shown, a change-over switch 3 is set for preselective control, the selection being by closure of a switch 5 or 5<SP>1</SP> and speed change occurring when push button contact a energizes a slow release relay 4, thus closing contacts 4a and 4a<SP>1</SP> to energize the appropriate main relay 1 or 1<SP>1</SP>. This causes closure of 1c, or 1c<SP>1</SP>, so energizing motor or coupling winding 8 or 8<SP>1</SP>. The main relay remains closed by hold-on contacts 1a or 1a<SP>1</SP> and normally closed push button contacts 6; first movement of this button therefore releases the previously energized main relay, and interlock contacts 1b 1<SP>1</SP>b prevent the simultaneous closure of two main relays and hence the selection of two speeds at the same time. The delayed opening of relay 4 ensures that contacts 4b provide an alternative path until contacts 6 re-close upon the button being released. With switch 3 changed over, the appropriate main relay 1 or 1<SP>1</SP> is energized when contact 7 or 7<SP>1</SP> is closed by a programme controller, not shown. The circuit could be expanded to include any number of motor or coupling windings 8 to provide more than two speeds.

Title: Process for catalytically oxidising hydrogen sulphide
IPC: C01B17/64
Filed: 1929-12-21
Abstract: Hydrogen sulphide or its salts are catalytically oxidized by oxygen in the presence of complex salts of heavy metals with cyclic organic compounds.  Industrial gases such as illuminating, coke oven, or producer gas are washed with water, or alkali such as sodium carbonate, and the solution of hydrogen sulphide or of sodium sulphide or hydrosulphide obtained, after addition of a solution of the catalyst, is treated with oxygen or gases containing the same, when oxidation to sulphur or sodium thiosulphate is effected. Ammonium, calcium and other hydrosulphides may be oxidized in the same way.  Suitable catalysts are made, according to examples: (1) by mixing an alcoholic solution of 1-oxyanthraquinone with ammoniacal copper hydroxide to form the complex copper salt, (2) by the addition of an alcoholic solution of alizarin to alcoholic manganese acetate, (3) by adding an alcoholic copper acetate solution to a solution of quinizarine in alcohol containing 16 per cent by volume of pyridine. In place of quinizarine, 1 : 2 : 8-trioxyanthraquinone or other suitable anthraquinone derivatives may be used.  A solution of h min in pyridine or disodium phosphate is also suitable.ALSO:Complex salts of heavy metals with cyclic organic compounds, used as catalysts for the oxidation of hydrogen sulphide and its salts, are made by mixing solutions in suitable solvents of the cyclic compound and a compound of the metal.  In examples: (1) an alcoholic solution of 1-oxyanthraquinone is mixed with ammoniacal copper hydroxide to form the complex copper salt.  (2) to 0,009 parts of manganese acetate dissolved in a little alcohol is added an alcoholic solution containing 0,02 parts of alizarin, with immediate formation of a solution of the complex salt: (3) to 0,02 parts of quinizarine in alcohol containing 16 per cent by volume of pyridine is added an alcoholic solution of 0,0086 parts of copper acetate.  In place of quinizarine, 1 : 2 : 8-trioxyanthraquinone or other suitable anthraquinone derivatives may be used.
