Title: Improvements in or relating to the manufacture of filaments for electric incandescent lamps
IPC: H01K3/02
Filed: 1935-12-11
Abstract: 467,187. Electric incandescent lamp filaments. GENERAL ELECTRIC CO., Ltd., and LEEDS, R. E. Dec. 11, 1935, No. 34370. [Class 39 (ii)] A process of manufacturing coiled-coil filaments for electric incandescent lamps comprises the following steps in the following order : (1) winding on a mandrel, so as to produce a primary helix, a tungsten wire of the kind known to be capable of growing long crystals almost instantaneously when the completed filament is first heated to the operating temperature ; (2) releasing part at least of the strain in the wire generated in the primary winding ; (3) winding the primary helix on a mandrel so as to form a secondary helix ; (4) removing the secondary mandrel, wherein the wire, between the beginning of step 3 and the end of step 4, never rises to a temperature above 1000 C. The releasing of the strain in the primary helix, which comprises step 2 may be effected either by heating the primary helix while on its mandrel to a temperature of at least 1500 C., or simply dissolving out the mandrel. If the latter operation is adopted, the primary helix is subjected to a slight tension while being wound on the secondary mandrel in step 3. After winding, a permanent set may be produced in the secondary helix by heating it, before the removal of the secondary mandrel to temperatures ranging from 400 to 800 C., according to the method adopted in releasing the strain in the primary helix. A suitable wire for the filaments may be prepared by subjecting a tungsten wire containing about 0À75 per cent of thoria to a thermo-mechanical process of the kind described in Specification 183,118, [Class 39 (ii)]. Specifications 6439/14 and 155,851, [both in Class 39 (ii)], also are referred to.
