<p>1,000,061. Selective signalling. HONEYWELL Inc. Jan. 17, 1962 [Jan. 17, 1961], No. 1798/62. Drawings to Specification. Heading G4H. [Also in Division G3] Electrical apparatus for controlling the energization and de-energization of a plurality of loads comprises a time signal source having a number of output channels on which time signals occur at different times, first selector switch means to selectively couple any one of the load devices to any one of the output channels for automatic energization of that load device in response to the occurrence of a time signal on that selected channel, and second independent selector switch means to selectively couple that load device to any one of the output channels for automatic de-energization of the load device in response to the occurrence of another time signal. In the arrangement as described, each load device is also associated with a storage relay and a scanning unit so that those load devices connected to the same output channel are energized or de-energized sequentially. Manual control facilities and an indicating lamp display unit are provided. The detailed circuit employing relays and rotary switches and conventional switching techniques is described.</p> |
