GB190324305 -- Improvements in Means for the Production of Continuous High Potential Electrical Discharges [ Oliver Lodge ]****GB191208197 -- Improved Method of and Apparatus for Producing High Tension or High Frequency Electric Currents.** For producing high-tension or high-frequency currents from a Ruhmkorff coil, a second primary coil 5 and a condenser 7 are connected across the interrupter 4 &c., so that the discharges of the condenser set up oscillations in the coil 5. The secondary 6 of the coil 5 may be connected to the secondary 3 of the usual primary coil 2, and the discharges from the secondaries may be utilized simultaneously or independently. A cautery 9 &c. may be connected in circuit with the coil 5 and the condenser. **GB190629086 -- Improvements in, and relating to, Exciting Ruhmkorff and other Electric Coils.** A reactance coil with an iron core consisting of a long bar or bundle of wires or thin strips is used for exciting a Ruhmkorff coil or other appliance where sudden generation of current is desired. The coil is excited by a source of current or by revolving it in a magnetic field, and by means of a two-way switch one or both of the connexions of the coil are suddenly shifted from the source of current to the circuit of the Ruhmkorff coil or other appliance. .. the iron core may be three inches in diameter and from two to three feet long. **GB190008067 -- Improvements in Harmonic Telegraphy.** Relates to harmonic telegraphy in which double reeds mounted to rotate on a stand are employed as the make and break of a Ruhmkorff coil the secondary of which is connected by both poles to earth or water..The receiver is similarly connected by both poles to earth. **GB751735 -- Modulated electric arc for chemical reactions** --- ---
