Abstract: SELF-OSCILLATING HIGH FREQUENCY POWER CONVERTER            Abstract A self-oscillating power converter utilizes a MOSFET power transistor switch with its output electrode coupled to a tuned network that operatively limits the voltage waveform across the power switch to periodic unipolar pulses.  The transistor switch may be operated at a high radio frequency so that its drain to gate interelectrode capacitance is sufficient to comprise the sole oscillatory sustaining feedback path of the converter.  A reactive network which is inductive at the operating frequency couples the gate to source electrodes of the transistor switch and includes a variable capacitance as a means of adjusting the overall reactance, and hence the converter's switching frequency in order to provide voltage regulation.  A resonant rectifier includes a tuned circuit to shape the voltage waveform across the rectifying diodes as a time inverse of the power switch waveform.  (FIG. 1).

Abstract: ABSTRACT          Garbage and other incinerable waste is treated with hot air and steam in a rotary furnace, under conditions in-hibiting free and complete combustion, so as to produce a gaseous phase and a solid phase consisting of non-combustible solids.  The gaseous phase is mixed with excess air and recirculated combustion gases and passed to a cyclone chamber in which further combustion takes place at a temperature controlled so as to destroy toxic organic compounds and to melt solids such as glass but insufficient to promote excessive nitrogen oxide forma-tion.  The gases are then passed through a ceramic heat exchanger, tempered with ambient air in a further cyclone chamber to cause any residual molten glass still entrained in the gases to solidify, and passed through a second heat exchanger, clean compressed air being passed through the second and then the first heat exchanger so as to raise its temperature sufficiently to drive a gas turbine.
