Abstract

350,204. Electric incandescent lamps. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London. -(Siemens & Halske Akt.-Ges. ; Siemensstadt, Berlin.) [Class 39 (ii).] Filaments.-Incandescent bodies are formed of rhenium or of a rhenium alloy, volatization in vacuo being less than for tungsten. Tungsten may be alloyed with a small quantity of rhenium. A filament of rhenium 0À2 mm. in diameter may be used at 2550‹ in a high vacuum. Reference has been directed by the Comptroller to Specification 309,536, (as open to inspection under Sect. 91 of the Acts), [Class 39 (ii), Electric lamps, Incandescent].
