Abstract

489,530. Heating by electricity. ZEISS, C., [Firm of]. Oct. 4, 1937, No. 26762. Convention date, Oct. 5, 1936. [Class 39 (iii)] An electrically-heated spectacle lens a<1> has a strip b of highly conductive metal applied direct to the glass by painting, cathode spraying, &c. The metal b is protected by a superposed lens all. The two lenses are held together by a binding. substance or they are fused together embedding the heating strip. Specification 436,132, [Group XX], is referred to.
