Abstract
1387856 Transistor pulse discriminating circuits J M MALATCHI 3 July 1972 [12 July 1971] 31101/72 Heading H3T [Also in Division H2] A circuit 25 for energizing a relay 225 when a signal applied to an input terminal 118, 119 or 120 exists for longer than a predetermined time comprises a transistor 206 which is switched off by the signal to enable a capacitor 214 to be charged from a D.C. supply fed to a terminal 210. If the input signal exists for a sufficient time, the voltage across the capacitor rises to the voltage at the control electrode 217 of a programmed unijunction transistor 218 which is therefore switched on and in turn switches on a transistor 224. The discharge of a capacitor 229 through the transistor 224 switches off a transistor 235 and therefore switches on a transistor 245 which in turn switches on a transistor 248 to energize the relay 225 via a D.C. supply terminal 110. The relay closes contacts 222 in the six channels of a stage lighting system (see Division H2).
