the unit is reversed causing the movable plate to rotate into a new position wherein air is permitted to enter the lower chamber to cause oxidation of the char this oxidation process continues until the char is entirely consumed and reduced to a sterile ash any gaseous products produced will continue to be oxidized in both chambers application_number US 40479089 A description referring now to the drawings wherein like reference characters designate like or corresponding parts throughout the several views there is shown a disposal unit 10 having an oxidizer 11 and a pyrolyzer 12 the oxidizer 11 includes an oxidation chamber 13 defined by a cylindrical wall 14 covered at one end by a ceramic honeycomb 17 and at the other end by a stationary slotted plate 19 wall 14 and plate 19 are attached to form a rigid structure the exterior surface of wall 14 and the adjacent exterior side surface of honeycomb 17 are covered with a heat insulator 21 mounted in an outer cylindrical shell 23 the shell 23 is rigidly attached near one end to the edge of plate 19 and at the other end has a lateral wall 25 and a lip 27 the wall 25 extends over the insulator 21 and abuts the upper edge of honeycomb 17 six radial slots 28 are symmetrically spaced on plate 19 to be located directly below the chamber 13 the honeycomb 17 has a central bore 29 to permit an electric heater rod 30 to extend into chamber 13 a movable plate 32 is.
