| An improved active grate consisting of at least two elongated rockers positioned parallel to one and another, each rocker having a lower surface and an upper surface and configured to rotate back and forth about their longitudinal axis. Each individual rocker is further configured to rotate in the opposite direction of the adjacent rockers such that any pair of adjacent rockers alternately forms a void allowing material to pass through active grate when rotating in one direction into a first position, and closes the void when rotated in the opposite direction in a second position. The active grate finds particular utility in a combined gasification/vitrification waste treatment system, where it is used to pass partially oxidized materials from a gasification chamber to a vitrification chamber. The rockers include a coolant loop through the longitudinal axis of the rockers. | ||||||

| A convertible cooking grate provides dual cooking surfaces for use with barbecue grills. In a first position, a grate-like cooking surface is formed by a plurality of spaced apart bars that support an item being cooked above the heat source. In a second position, a substantially flat griddle-like cooking surface is formed by a plurality of bars having substantially coplanar surfaces that fit closely together. The bars are rotatably supported by pins that extend from each end thereof and fit into corresponding holes in an outer frame. A mechanical linkage is provided to rotate the bars together simultaneously between the first and second positions. | ||||||
