Abstract: Alternators/generators of axially disposed air gap conformity in which a unique combination of rotors and stators results in machines of high efficiency, simplified modular assembly and extension. Such machines can, moreover, be readily constructed to produce from a single alternator unit multiple voltages and frequencies and from a single generator unit direct current in multiple voltages.

Abstract: A vapor cycle power system in which the low level heat source is furnished by water or air via the medium of a compression cycle heat pump, and subsequent higher temperature level heat energies are provided by direct combustion, solar energy, geothermal energy or waste heat, singularly or in combinations thereof, in either or both gaseous or liquid forms. In certain embodiments of the invention, the system has the capability to provide heating and cooling in addition to the function of producing useful shaft work.

Abstract: A prime mover of internal or external combustion type is utilized to furnish shaft work for the driving of an electrical generator, a refrigeration compressor and/or a combination of both. Waste heat emanating from the prime mover and/or a refrigeration system, of which said compressor is a component, is directed to provide utility heating and/or air conditioning, said heating and air conditioning thereby becoming useful byproducts of a means for generating electrical energy and/or furnishing refrigeration.

Abstract: An alternator/generator of modular construction in which a plurality of magnets are so arranged on the face(s) of a rotor(s) of disc or flywheel conformity as to interact with axially oriented and aligned pole pieces of magnetic material, in order to create a flux field across an air gap. A stator(s) cooperating with the rotor(s) comprises in part the pole pieces referred to in the foregoing, and about which are wound induction coils calculated to produce predictable quantities of electrical energy in a multiplicity of voltages and frequencies either simultaneously or otherwise.
