Abstract

5768. Frankenburg & Sons, I., and Fleming, E. April 17. Lighting systems.-A lighting-circuit includes an auxiliary resistance or one or more high-voltage lamps E in parallel, and a number of low-voltage lamps C in series, each lamp C being shunted by a resistance D of slightly greater value than the lamp resistance. The system is particularly adapted for lighting sewing-machines. Specifications 7850/88 and 12,398/08 are referred to.
