Abstract

273,257. Soc. Anon. Hewittic, and Demontvignier, M. June 22, 1926, [Convention date]. Drawings to Specification. Controlling consuming devices. - A mercury switch mounted on the end of a bimetallic current-carrying strip is used in a short-time staircase lighting system (Fig. 28 not shown). Charging and discharging batteries. - A mercury switch, mounted on the end of a bimetallic strip is also used with automatic vapour rectifiers for charging accumulatcrs (Fig. 29, not shown), the bimetallic strip moving so that the rectifier is in circuit first with a resistance, then with the resistance and battery in parallel, and finally with the battery alone.
