Abstract: A method for assembling a gas turbine engine including a compressor and a combustor includes providing a heat exchanger assembly that includes at least one heat exchanger, and coupling the heat exchanger assembly to the gas turbine engine such that the heat exchanger is positioned substantially concentrically with respect to a gas turbine engine axis of rotation, and such that the heat exchanger is configured to channel compressor discharge air from the compressor discharge air to the combustor.

Abstract: A default engine control method for an internal combustion engine recovers from the loss of a high-resolution engine position signal by calculating a high resolution pulse period based on a recognized pattern of a low resolution engine position signal. Interrupts for signaling the execution of cycle-related control algorithms are scheduled in time based on the calculated pulse period, and pulse period errors due to changing engine speed are periodically corrected based on the timing of subsequent transitions in the low resolution position signal relative to the scheduled interrupts.

Abstract: A method and apparatus for the precombustion identification of a cylinder undergoing compression in an internal combustion engine is disclosed. An electrode gap (e.g., preferably a spark plug) is disposed within a cylinder of an internal combustion engine. The electrode gap is provided with a voltage differential from a power supply through a circuit (preferably an RC circuit). The engine is cranked, and the voltage differential across the electrode gap is monitored during the cranking of the engine. With appropriate choices of the voltage differential across the electrode gap, the resistance R of the circuit, and the capacitance C of the circuit, voltage pulses are produced across the electrode gap during such time when the cylinder is not undergoing a compression stroke. Such voltage pulses are suppressed when the cylinder is in fact undergoing a compression stroke due to a rise in the breakdown voltage across the electrode gap, in accordance with Paschen's Law.

Abstract: A self-locking drive, for use in door/gate operators is disclosed. The method/means incorporates an electric motor, which has a rotor assembly that can slide axially in its casing. A brake cone is fixed to the rotor-shaft, which can engage a complimentary brake cone that is attached to the motor casing. At rest these brake cones are very lightly engaged due to an axially mounted spring. The components of the system are designed and configured that any attempt to open the closed door/gate results in the brake cones being forced tighter together. This results in further engagement of the of the brake cones which further resist opening of door/gate. The forcing of the cones together is achieved by helical spur gearing. During motorized closing, the stator's centering pull on the rotor at full load, just balances the axial thrust due to the meshing helical gearing. Consequently, the brake cones do not engage during closing of door/gate.
