Abstract: An electronic fuel control system for varying the fuel flow to a gas turbine engine during the engine's acceleration. The reference speed set point of the engine's fuel controlling governor is increased as a function of the elapsed time from engine start-up and the engine characteristics so that the engine accelerates substantially along its "required to run line.
Abstract: Trim signals are removed from the fuel control computers of aircraft propulsion engines to increase thrust upon detection of a predetermined difference between engine speeds.
Abstract: An air-curtain incinerator for burning energetic materials. Both the volume f air and the angle at which air enters the fire box are remotely controllable. The combustion process is monitored, and the air volume and angle at which air enters the fire box are controlled to minimize the production of air pollutants by the combustion of energetic materials.

Abstract: A system for warning a target designator operator whenever a target less n a predetermined distance from the operator is designated. Actuating the target designator triggers a time interval counter and circuitry to detect reflected pulses. An indicator will warn the operator if a pulse is reflected to the system from an object less than a predetermined distance from the operator.

Abstract: By using two or more series connected silicon controlled rectifiers a laser odulator is created which provides higher current, faster rise time and narrower pulses than can be provided by existing single or multiple silicon controlled rectifier circuits. In an example circuit using two such rectifiers, the first is gate triggered and the second is turned on by a rapid voltage increase across its anode and cathode.
