Alternating electrical energy generator - has reciprocating piston or membrane compressing gas and increasing Curie temperature of foils

摘要

A machine for producing alternating electrical energy with permanent magnets supplying a magnetic circuit via closed iron paths which are converted periodically into alternating fluxes. A reciprocating piston (P) or a membrane (M) produces compression heat of a gas, which is used to heat ferro or ferri magnetic foils or sheets, in the enclosed iron magnetic circuit, to their curie temperature. The gas which is compressed and heated in one of the two cylinder chambers (7) by the piston or the diaphragm, flows through slits or other openings in the foils into chambers (9). The foils are heated during this process, and are then cooled by another flow of gas which is compressed in the other cylinder chamber (8) and originating from other chambers (10).
