Title: Improvements relating to chutes or hoppers
Inventor: BUSH ANTHONY
IPC: B65G11/16
Filed: 1982-08-02
Abstract: Chutes and hoppers often have linings to prolong life, reduce noise and spark risk, or to cushion the product being handled. Instead of a continuous sheet lining, panels (1, 15, or 18) are hung in tile-like fashion over the wear surface, and are individually replaceable. The top row of panels may hook onto a rail (9) fixed to the chute or hopper (6), with the next row hooking to that top row behind its lower edge and so on. The lower edge of the bottom row will engage and be retained by a removable rail (11) (Figure 3 not shown). The panels may be of composite construction, having a steel plate (1) with a resilient facing (2), and hook formations (4, 5) may be bent out of the plane of the plate. Alternatively, the panels may be plastics or rubber sheets (15) (Figure 5 not shown) with hooks (16, 17) partially embedded in them, or integral sheets (18), (Figure 6, not shown) having hooks (19, 20) formed by extrusion. <IMAGE>

Title: A method and apparatus for rendering polychlorobiphenyl virulence-free
Inventor: KITAMURA YOSHIAKI
IPC: B01J21/00
Filed: 1984-03-27
Abstract: PCB (Polychlorobiphenyl) is pre- heated before it is introduced into a combustion furnace (1), and is caused to ascend through a layer of mineral catalyst particles (6) disposed above a grid (3) in a vessel (2) in the furnace, the mineral particles being of a porous multi-element material capable of producing metal oxide when heated. The furnace interior and particularly the mineral particle layer are pre-heated to a temperature above 1,100 DEG C. During the consecutive reaction processes of gasification, dissocation and combustion of PCB brought about as it ascends through the mineral particle layer, the thermal dissociation into benzene and chlorine and further combustion of benzene are promoted by the catalytic actions of multi-element oxides present on the pore surface of the mineral particles. The exhaust gases from the furnace are fed through a gas treatment tank (13) to absorb and neutralize chlorine gases therein. The furnace (1) has an aperture (1a), at which a burner (9) and a fan (10) are movably disposed, e.g. on a guide rod (11). <IMAGE>
