An improved rotary kiln having an elongated kiln member formed of refractory material and supported for rotation, a tubular liner in the kiln member formed of electrically conductive material, a stationary tubular structural non-electrically conductive member concentrically surrounding the kiln and of interior diameter greater than the exterior diameter of the kiln providing an annular space therebetween, an induction coil wound on the exterior of the tubular structural member and an AC source connected to the induction coil and means of rotating the kiln member, the induction coil heating the tubular liner to heat contents within the kiln as the contents are tumbled by rotation of the kiln.

Induction heated rotary kiln

A system for providing a regulated low voltage DC source and a regulated higher voltage AC source at a preselected frequency, such as 60 Hz. from the same windings of an alternator rotated at variable speeds including a phase WYE connected engine driven alternator providing three output posts and a neutral post and having a field circuit, a half-wave rectifier connected to each of the output posts of the alternator providing a low voltage DC source, a cycloconverter having a three phase input connected to the posts of the alternator and providing a single phase output at the preselected frequency, a resonating transformer having the primary connected to the output of the cycloconverter and having a capacitor in the secondary providing a resonant frequency at the desired AC frequency, such as 60 Hz., and a clock circuit providing an AC control voltage at a preselected frequency, such as 60 Hz., the clock being connected to the cycloconverter for control of the cycloconverter to provide the selected input frequency to the resonating transformer. The secondary of the resonating transformer providing the AC voltage source at the preselected frequency and a regulator circuit controlling the field current of the AC generator for regulating the AC voltage output of the resonating transformer.

Dual voltage generator system

A method of converting organic materials into useful products and disposable waste including the steps of shredding the organic material into particles, mixing the organic particles with water to obtain a pumpable slurry, raising the temperature and pressure of the slurry to about 300.degree. to 500.degree. C. and about 8000 to 12,000 psig in a reaction vessel to cause the slurry to hydropyrolyize, separating the products of hydropyrolysis to remove gases from the liquids and solids, separating the liquids and solids, treating the separated gases and liquids to extract hydrocarbon components therefrom and using the solids as fuel directly.

Apparatus for producing induction currents in a pipe to heat the same comprising an axially extending collar adapted to removably surround the pipe, the collar including at least two arcuate frames hingedly connected in end to end circumferential relationship and having a pair of free ends adapted to be opened for placing the frames around the pipe, a plurality of electrically conducting wires carried upon the frames across the axial width thereof and extending circumferentially between the free ends, a connector assembly mounted at each free end, each connector assembly having a plurality of connectors, each connector of each assembly being connected to an end of a wire and being connected electrically to a connector of the other assembly when the frames are in closed position around the pipe, the wires on one axial half of the collar being connected to each other to form two interlaced bifilar windings; the wires at the other axial end of the collar being interconnected to form two interlaced bifilar windings arranged in end to end axial relationship with the bifilar windings of the first axial end of the collar thereby resulting in an overall quadrafilar winding for the collar, and a source of alternating electric potential connected to the windings to produce induction heating in the pipe.
