24,785. Mitkevitch, V. Nov. 30. Welding; working by electricity.-Extinction of continuous-current electric arcs in welding and other metal-working processes is prevented by applying auxiliary heat to the negative electrode or to both electrodes, as described for alternating- current arcs in Specification No. 20,769, A.D. 1905. The auxiliary heat may be supplied by an oxyhydrogen blowpipe or by a subsidiary arc. By this means, the arc can be produced without contact of the electrodes. [Reference has been directed under Patents Act, 1902, to Specifications No. 2339, A.D. 1879, No. 22,233, A.D. 1901, and No. 26,145, A.D. 1903, [Abridgment Class Electric lamps &c.].]
