Abstract: A method of manufacturing drilling crowns for cylindrical diamond drilling tool bits affords a waste-free fabrication of the drilling crowns impregnated with diamond particles. In a first step an annular axially extending middle or intermediate zone impregnated with diamond particles is joined at each of its opposite end by sintering to a different annular metal end zone. In a second step the intermediate zone is laser cut to form two similar drilling crowns with circumferentially spaced teeth. The teeth form diamond segments providing economical fabrication and a high quality connection with the end zones.

Abstract: Combustible gases are produced from a solid fuel by pyrolizing the fuel in a pyrolyzer containing a low grade solid fuel producing combustible gases, and carbonaceous material that is combusted in a furnace to produce hot products that include hot flue gases and particulate material. The hot products are separated into a plurality of streams, one of which contains comparatively coarse ash which is directed into the pyrolyzer for effecting the pyrolyzation of the fuel. A stream of reaction gases is applied to the pyrolyzer in such a way that the stream of reaction gases bubbles through the carbonaceous material in the pyrolyzer without fluidizing such material. In effect, the reaction gases activate the void fraction in the pyrolyzer thereby reducing the residence time of the material therein.
