Abstract: This invention is an engine where the working fluid may be in either a closed circuit or an open circuit. The engine may be powered by heat stored in an easily rechargeable high temperature phase change system or by heat of combustion directly. Also disclosed is a portable device incorporating the engine optionally as a) an electrical generator b) a source of refrigeration in remote environments c) a source of rotating mechanical power in remote environments. Also disclosed is a stationary device incorporating the engine and phase change thermal storage system as a co-generating heating and refrigeration system for widespread application. Also disclosed is a vehicle catalytic converter pre-heater incorporating a phase change thermal storage system and engine.

Abstract: The invention is two new ways of constructing a synchronous dynamo electric machine having either permanent magnet or electrically excited field poles and no active electrical or magnetic parts attached to the rotor. Also shown is a means of using one or more such machines connected to prime mover engines to synchronize rotation or dampen vibration within the engines as well as acting as a motor or generator. Further shown is a means of constructing a dynamo electric machine in a configuration which particularly suits application as an auxiliary alternator on an automotive piston engine.

Abstract: This invention is a new dynamo electric machine of the synchronous alternating current type designed to be installed as the wheel of a motor vehicle. Disclosed are three primary embodiments which together or in combination can be applied to the purpose. Also disclosed is a means of ensuring coordinated operation of several of the machines installed onto the same motor vehicle while maintaining a simple central control system.
