Abstract

950,489. Alarm systems. G. F. W. POWELL, and MOLINS MACHINE CO. Ltd. Jan. 12, 1962 [Jan. 13, 1961], No. 1538/61. Heading G4N. A circuit, particularly for indicating the failure of a heater 10A in a machine, and including a warning lamp 6, is characterised in that the lamp 6 is in the secondary circuit of a transformer maintained in a saturated condition so that an increase in primary current due to failure of the heater 10A will not burn out the lamp.
