Title: Low speed circuit for async. three=phase motor - uses series connected diode to partially suppress one phase
IPC: H02P23/10
Filed: 1977-02-23

Title: Refuse incinerator gas heater - has electric elements with refractory blocks to re-radiate heat to gases
IPC: H05B3/10
Filed: 1977-04-20
Abstract: The hot gases used in incinerators for burning rubbish are heated primarily by allowing the gases to flow over electric heating elements (10).
