Abstract

1283261 Sequence timing circuits SOC INDUSTRIELLE BULL - GENERAL ELECTRIC 9 April 1970 [9 April 1969] No 17012/70 Heading H3T A sequence timer comprises a multivibrator T1Gi, TD, having complementary outputs 18Gi, 18D connected to respective trigger inputs of the two-bi-stable circuits of a counter, each bi-stable circuit having complementary outputs SB, SB connected to complementary inputs of the other bi-stable circuit, the arrangement being such that when operation is initiated a sequence of two marks and two spaces is produced, the counter having at least one output connected to the multivibrator to alter its timing. As shown, the multivibrator has resistors RX, RY in parallel (or series) with timing resistors 24G<SP>1</SP>, 24D and connected into circuit when the counter transistor to which it is connected becomes conductive. Two counter outputs together with a start signal input are applied to an input gate (Fig. 3, not shown) connected across the multivibrator at E3D or E3G<SP>1</SP> to normally hold the multivibrator off in a desired state. The start pulse opens the gate to allow the oscillator to pass through the fan on off periods timed in accordance with the connections to the parallel timing resistors, after which the inputs from the counter cause the gate to terminate oscillation. The multivibrator is of the type using a single timing capacitor c connected between the emitters of alternately conducting transistors T1Gi, T1D.
