Abstract: 668,762. Impedance networks. DU MONT LABORATORIES Inc., A. B. Jan. 4, 1950 [Jan. 15, 1949], No. 216/50. Class 40 (viii). [Also in Group XL (c)] A voltage gain control circuit comprises a number of resistances connected as a Wheatstone bridge, with the input applied to one diagonal, a potentiometer connected across the other diagonal and a reactance connected across one leg of the bridge. As shown, resistances R1, R2, R3, R4 are connected as a Wheatstone bridge in the cathode circuit of an amplifier valve 10. The input to the following valve 22 is taken from the moving contact of a potentiometer R5 connected across the diagonal of the bridge. A condenser 13 is connected across one leg of the bridge. The bridge is balanced for D.C. so that no objectionable disturbances arise from variations in the D.C. component fed to the following valve when the gain control is adjusted. The condenser 13 is chosen so that the junction of resistors R2, R3 and potentiometer R5 is earthed over the useful frequency band. The arrangement may be connected in the anode circuit of a valve.

Abstract: 637,489. Press-button retractive switches; momentary contact switches. VICTOR PRODUCTS (WALLSEND), Ltd., and HYSLOP, E. Jan. 7, 1948, No. 536. [Class 38 (v)] [Also in Group XXXVIII] A normally-closed, press-button switch suitable for use in colliery lighting and signalling systems, re-establishes the circuit automatically after a short delay should the press-button be held depressed in the switch-open position. The movable contact 44 normally bridging the pin head contacts 39, 41 has apertured ends which slide over insulating sleeves 42, 43 against the action of springs 46, 47, and is carried by the stem 49 of a piston 51 slidable in the pressbutton extension 52. On depression of the button 53 air is compressed to the right of the piston 51, the left side being open to the atmosphere by the loose fit of the button in the housing 32 and gland nut 57, whereby the piston moves to open the circuit between the contacts 39, 41, the switch being immediately re-closed by the springs 46, 47, 56 on release of the button. Should, however, the button be held depressed, air leaks through a small hole 59 in the piston and permits the springs 46, 47 to restore the contact 44 after a delay of 2 or 3 seconds. The delay may alternatively be provided by a gear train. The switch may be incorporated in a lighting fitting (Fig. 1, not shown).

Filed: 1982-01-07
Abstract: The ammonia contained in ammonia- and hydrogen sulfide-containing gas mixtures is selectively removed through a gas washing with an aqueous ammonium sulfite-bisulfite solution, and recovered from the wash solution as a concentrated aqueous solution. For this purpose the coke oven crude gas is washed with an ammonium sulfite-bisulfite solution led in circulation, the surface tension of which amounts to below 80x10-5 N/cm, then the ammonia gas is driven away from the wash solution enriched with ammonia, e.g. by means of steam, and the released ammonia is recovered e.g. as aqueous ammonium solution through condensation of the vapor. The gas mixture is preferably purified or unpurified coke oven crude gas. In order to reduce the surface tension of the wash solution, alkyl sulfate, alkylamine, pyridine base, phenol or homologs thereof are added as surface active substance. The wash circulation is performed at between 15 DEG  and 32 DEG  C.
