摘要： The invention relates to a step switch assembly which switches power on and off in a stepwise manner in dependence upon the upper and lower limiting values of a control signal. The switch assembly may be used for operating in a stepwise manner a bank of units such as motors wherein each motor, or group of motors, represents a portion or part of the total available capacity of a system such as air conditioning system. The step switch assembly includes a reversible counter, a transmitter for sending digital impulses to the counter, and power stages which are switchable on and off in dependence upon information stored at the counter output points.

摘要： Redundant but independently operable data processors called encoders are arranged so that control of a particular recorder gathering billing data in a telephone switching system can be transferred while maintaining billing continuity for calls being handled by that recorder. More specifically, each encoder checks the validity of billing information received from each recorder. However, each encoder only transmits billing data pertaining to a designated group of recorders to a remote processor. When an encoder detects that it is not receiving valid data from one of its designated recorders, the control of only that designated recorder is transferred to the other encoder if the other encoder indicates that it is receiving valid data from that recorder. Moreover, the relinquishing encoder sends a message to the remote processor indicating that it is giving up control of the designated recorder, while the accepting encoder inhibits the transmission of information to the remote processor for a predetermined time interval and then transmits a message indicating that it has accepted control of the designated recorder. This delay ensures that the remote processor will receive the relinquish message before the acceptance message so that the continuity of processing billing data for calls handled by the designated recorder can be maintained.

摘要： A device for controlling a gaseous or liquid fuel fired appliance as a function of a parameter includes a fuel supply controlled by a valve operated in dependence on a signal furnished by means sensitive to the parameter. The device includes a first circuit triggerable by the parameter-sensitive means when the parameter exceeds a first value and a second circuit triggerable by the parameter-sensitive means when the parameter falls below a second value lower than the first value. These circuits operate the valve appropriately for a given period of time. The device includes a spark generator for ignition of the fuel and an inhibitor to stop spark generation on fuel ignition. The device also includes first and second dc sources for independent supply of the first and second circuits, which require negligible current when not operative.

摘要： A control system for controlling a condition, such as temperature, to maintain that condition in a generally enclosed space near a selected condition value. The system has a condition responsive impedance in series with a selectable impedance across a regulated voltage source to provide a voltage divider network, the output of which reflects the instantaneous condition of the environmental space relative to a selected condition therefor. This output is supplied to a Schmitt trigger circuit having hysteresis characteristics sufficient to provide a stable operating mode for the control system, and the Schmitt trigger circuit output controls a means for changing the condition of the enclosed space. A manual mode selecting switch may be provided for inserting any of several different impedances in the series combination, and a timer may be provided to automatically switch between different impedances in the series combination as determined by elapsed time with respect to application of power to the circuit.
