Abstract
267,553. Lampl, A. March 13, 1926. [Convention date]. Addition to 249,048. Controlling consuming devices. - In devices for automatically inserting an equivalent resistance into a series circuit upon failure of one of the lamps &c. therein, and wherein the resistance comprises a packed mass of metal particles as described in the parent Specification, either a fixed resistance d, Fig. 1, is placed in series with a cohering resistance c comprising a mass of small balls, like lead shot, or a cohering resistance d<1>, Fig. 2, is used which comprises metal particles, such as iron filings, mixed with about an equal volume of non-conducting and heat-resisting binding material, for example gypsum, cement or chamotte. This resistance may be packed between the metal shell b of the lamp cap and a metal cylinder c<4> electrically connected to the centre contact a, so that when the filament g breaks the current passes through the resistance d'.
