Abstract

611,221. Inductances. NEWTON, E. P. (American Bosch Corporation). Oct. 4, 1945, No. 25898. [Class 38 (ii)] [Also in Group XXXVI] A coil which may be used in sparking-plugs, electrical instruments and radio is made by spreading layers of metallic material on the ends of a heat-resistant inorganic former and baking them, winding insulated or bare wire on the smooth or grooved former with bared ends on the conducting material, covering these bared ends with further metallic material and baking them in position to form the coil terminals. The former 1 may be of steatite, glassbonded mica or ceramic material, and the metallic layers may be of a paint or paste of 90 per cent silver and 10 per cent platinum; gold may be added. Pastes containing these metals in pure form may be used. The inner metallic layer 3 may be baked into the pores of a ceramic former at 1000-1100‹ F. for 3-5 minutes and the outer layer baked on the wire 4 at 300‹ F. for 3-5 minutes, the wire insulation being of a material which withstands at least 600‹ F. The wire ends may be held by tapes or clips during bonding, and another layer of similar paint then applied and/or a coat 8 of metal such as silver or copper may be deposited electrolytically or by spraying to form the terminals 7. In a modification shown in Fig. 6, a spring 13 is fastened to a cross-wall 10 by a brass rivet 14 to form a resilient terminal. The metallic coatings by which the coil ends are bonded are continued across the end wall to make contact with the spring.
