Abstract

183,523. Colebrooke, A. H. S., and Williams, W. A. March 23, 1921. Repairing; filaments, attaching; residual gases. - In renewing filaments, a small weight is attached to the new filament 14 to retain it in the hook 13 of a leading-in wire 5 until the hook is bent over to secure it, and the weighted end of the filament is then cut off. The weight may comprise a coiled spring 15 or a pivotedjaw clip 17. To provide access to the filament support the tip of the bulb is out off, and d the hole so formed is widened out as at 3, or a sealing- tube may be first attached to the tip and the bulb then severed around the neck 2a. Broken filament-supporting wires may be replaced before the bulb is resealed, and a preparation of phosphorus may be sprayed into it or into the sealing- tube to improve exhaustion of the bulb, in known manner. Tools are described for manipulating the wires and filament.
