Abstract: A binary counter includes a number of cascaded flip-flop stages, each stage having an input transformer, the primaries of which are serially connected, in the ladder form, to one another across the output terminals of a constant current pulse generator. Each transformer secondary coil is connected to an associated flipflop toggle input. The low voltage side of each primary winding, in addition to being connected to the low voltage side of the succeeding primary winding, is also connected to the low voltage side of the constant current pulse generator through a stage associated switching transistor. The transistor is biased on or off by the signal appearing on one of output terminals of the transistor''s associated flip-flop. Thus, an input pulse from the constant current pulse generator, will be applied to the primary winding ladder down to the stage whose associated transistor is biased on, at which point the pulse is returned to the pulse source. If the switching transistors are turned on by a logical '''' 0'''' in their associated flip-flops the circuit will operate as an incrementer, while a circuit whose switching transistors are turned on by a logical '''' 1'''' in their associated flip-flops will operate as a decrementer to respectively add or subject the applied pulse to the count stored in the cascaded flip-flops.

Abstract: This invention describes a pulse gate which is useful with information present in a digital format the system is composed of an input circuit and a control circuit. The control circuit is capable of generating signals which inhibit the system and thereby prevent an output therefrom during the presence of input signals on the input terminal. The system utilizes a pulse transformer, the secondary of which is used to generate the output pulse. A logic AND gate is used to control the inhibit function. A logic OR gate can be used to receive the input signal. These two logic circuits are connected to opposite sides of the transformer primary. The inhibit circuit is designed such that the control times for the enable and inhibit functions can be discretely chosen. The use of a pulse transformer in the system has several distinct advantages. Firstly, the transformer affords an excellent opportunity to match the impedance between the input and output terminals of the system. Excellent isolation between the input and output terminals is also realized by the use of the transformer. By selecting the inductive coupling of the transformer the polarity of the output can be chosen irrespective of the polarity of the input signal. A multiprimary transformer can be used and thereby increase the versatility of the system. By using such a transformer the system acts as a logic OR gate, each input of which can likewise be a logic OR gate.

Abstract: A solid-state circuit for supplying constant power to a varying resistive load in response to a control voltage includes a light source and a photosensitive resistor. Load current is generated by a load current generator operating in response to a control signal. Resultant voltage drop across the load controls a second current generator which is serially connected with a light source. A third current generator, controlled by an independent control voltage, is serially connected with a photosensitive resistor exposed to the light source. Voltage on the photosensitive resistor comprises the control signal which controls the load current generator.
