Abstract
404,598. Resistance materials; coatings and deposits. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 11, 1932, No. 10357. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 11, 1932]. [Class 37.] High ohmic resistances, loading resistances, heating resistances, and hot cathode materials comprise admixtures of oxides of cobalt and nickel. Oxides of zinc, copper, aluminium, barium and magnesium may be added, or may be substituted for the nickel and cobalt. The mixtures in solid form may be obtained by melting the oxides together, or by precipitation, or by oxidising alloys. Solutions or melts of nitrates or carbonates may be heated on a porcelain or other non-conducting support, for example, an aqueous solution of 10 per cent cobalt nitrate and 10 per cent nickel nitrate may be formed into an oxide coating. The oxide mixture may be sintered by further heating, under pressure if necessary.
