Abstract: The thermodynamic compressor has a pair of conduits, each of which is wound into a group of loops arranged to form a toroid around a rotational drive axis. Each of the loops has an outwardly-extending section, and an inwardly-extending section which is spaced from the outwardly-extending section longitudinally along the rotational axis of the shaft. Each group of loops has the same number of loops in it, and corresponding loops in each of the groups are arranged directly opposite one another and working fluid is introduced in parallel into the groups of loops so that the amount of fluid in each pair of corresponding opposed loops remains the same at all times despite compression of the working fluid in the loops. The loops are arranged with the outwardly-extending sections in one plane, and the inwardly-extending sections in another plane so that heat easily can be added from the outside to the inwardly-extending sections and can be extracted easily from the outwardly-extending sections.

Abstract: A power supply apparatus having minimal power dissipation for supplying a substantially constant voltage regardless of the variation of an input voltage. A transformer having primary and secondary windings is provided to receive an input voltage and to produce an output voltage from which the substantially constant voltage is derived. The turns ratio of the transformer is varied in response to variations in the amplitude of the input voltage which exceed a predetermined range such that the turns ratio is reduced when the input voltage is increased and the turns ratio is increased when the input voltage is reduced. In one embodiment of this invention, when the supplied substantially constant voltage exhibits variations of greater than predetermined magnitude, an audio signal processing circuit which is powered by the substantially constant voltage is substantially disabled.
