Abstract

1,081,762. Horns. JOSEPH LUCAS (INDUSTRIES) Ltd. June 24, 1964 [June 27, 1963], No. 25574/63. Heading G5J. Energization of a diaphragm operating coil 13 in series with a transistor 12 opens the horn contacts 9 resulting in the transistor being cut-off. The subsequent de-energization of the coil and closure of the contacts completes the cycle. Resistor 14 provides some of the operating current for the coil, which by itself is insufficient to operate the coil.
