Title: Means and methods for electrolytically treating ferrous metal objects
IPC: C25F3/06
Filed: 1924-09-11
Abstract: 248,797. Potter, E., (Madsenell Corporation). Sept. 11, 1924. Metals, pickling; nickel and other metals, depositing.-Iron or steel sheets or other objects are pickled by treatment as anodes in a bath of sulphuric acid of concentration not less than 84.5 per cent. The cathode is preferably an iron or steel plate but may be a plate of lead or of other metal covered with lead. The cell is lined with lead. A current supply at 24 volts is used with a series resistance of such value that the voltage across the cell is 1 to 8 and preferably 6 to 8 volts. The initial current density is from 20 to 50 amps. per sq. ft. The operation is carried on until the current density falls to a fifth or a tenth or less of the initial value; this usually occupies about three minutes. The operation may be preceded by electrolytic or non-electrolytic pickling in an ordinary bath. After the special pickling, the objects are washed in slightly ammoniated water and then in pure water. The articles may afterwards be coated with zinc, lead, tin or other metals by electrolysis or otherwise, but are preferably coated with nickel by the processes described in Specifications 244,166 and 244,167. In order to ensure maximum adherence the coating operation should be commenced within about a minute, and preferably while the articles are still wet. Alternatively, the articles may be enamelled.

Abstract: 515,241. Wireless signalling. FERNANDEZ, M. G., and-FIGUEROA, E. O. July 20, 1938, No. 21509. [Class 40 (v)] In a transmitting system where the carrier is modulated both at supersonic and signal frequencies, the supersonic frequency is produced by heterodyning two radio frequencies, each of which is crystal-controlled. The carrier-wave is generated by a crystal-controlled valve 76 in unit B, and is modulated in the succeeding stage 6K7 by a supersonic frequency supplied from the unit D. This unit includes a heterodyne oscillator 6A8, the anode and grid circuits of which are separately controlled by crystals, the resulting "beat" frequency being amplified by the succeeding stages 6K7 before passing to the unit B. Low-frequency signals are applied to the grid of a valve 76 in unit C, and, after being amplified by the valve 42, are applied to modulate the supersonic frequency in the output of the valve 6K7 in unit D. The valve 6L6 in unit B amplifies the resulting modulated wave, and feeds it to the final output 807.
