Abstract: A thermal machine that can function as either a refrigerator or an external combustion heat engine is disclosed. A working gas undergoes four thermodynamic processes that comprise a Brayton cycle. Two of these processes, adiabatic compression and adiabatic expansion, take place in the same cylinder, within which a piston, driven by a crankshaft, reciprocates. The remaining two processes, each of which is a transfer of heat at constant pressure, take place in a high pressure heat exchanger and a low pressure heat exchanger. A rotary valve, rotating at one-half crankshaft speed, creates passages between the cylinder and the heat exchangers, and is constructed so that compression and expansion ratios are equal.

Abstract: A method of forming a wound roll, such as a regenerator, including the steps of inserting wires at the lateral edges of an elongated strip as the strip is being wound around a spool. Spacers, such as localized bumps, are formed on the strip to space strip layers apart to form uniform gaps. An offset is added to the angle of rotation between each spacer-forming step to inhibit the nesting of bumps in the cavities of adjacent strip layers.

A box-beam parcel shelf mounts at opposite sides to the region of the automobile body to which a suspension component attaches, such as the wheel house or rear inner panel. The box-beam parcel shelf substantially rigidities the automobile body, especially in combination with the damper stiffener extensions, which together form a contiguous structural reinforcement with the rear panel.

Abstract: The free piston cooler transient temperature control system of the present invention eliminates collisions during the transient cool-down period in a free piston cooler upon start-up. The transient temperature control system incorporates a free piston cooler, having a cold head and a warm end, a cold head temperature sensor, a relational interface, and a temperature controller. The cold head temperature sensor senses the temperature of the cold head and generates a temperature signal. The relational interface is in communication with the temperature signal and contains a predetermined relationship between the cold head temperature and a maximum piston stroke during the transient cool-down temperature range. The relational interface generates a transient range maximum allowable stroke signal from the temperature signal and the predetermined relationship.
