Apparatus for handling ash. A tank is filled with water and has the lower end thereof located at a substantial angle from horizontal. The tank is positioned beneath an incinerator to receive ash therefrom. An ash wheel having sectors defined by upright paddle elements has a portion thereof received beneath the water into which the ash falls and a portion thereof which extends over one edge of the tank. As the wheel rotates, ash is swept over the edge of the tank and onto a conveyor for disposal.

A large capacity air-powered flare for smokeless combustion of very large volumes of vented waste gases, comprises a first inner vertical conduit of diameter D1, for the flow of waste gas, and a second larger coaxial conduit of diameter D2, for the flow of primary combustion air, at a selected velocity in the annular space therebetween. Above the top the inner conduit there is a cylindrical obstruction of diameter D3 which is greater than D1, but less than D2. This forces the upwardly flowing gases to be deflected outwardly and upwardly into the second annular space between the obstruction and the outer conduit. The velocity of primary combustion air in the second annular space is at least 50 f.p.s., which serves to thoroughly mix with the inflowing gases so that as they rise through the second annular space they continue flowing above the top of the flare as an annular wall of high velocity gas, air and flame. This high velocity annular flow has large surface area on the outside and inside. Because of the high velocity of flow, secondary air is induced into the outside wall of this column, and also axially downwardly into the interior of this flow, where it moves radially outwardly to intersect the flowing gas and provide additional combustion air.

An improved low pollution invisible flare burner comprises a tall stack lined with ceramic. The stack is supported above the ground level and has a wind screen surrounding the open portion below the stack floor. Primary air is introduced under pressure in a tube below and coaxial with the stack. The top of the tube contains a burner for the vented hydrocarbon gases. The top of the tube and the burner are at the level of the floor of the stack. Secondary air is introduced into the stack in the annular space between the primary air conduit and an opening in the floor of the stack. Turbulent mixing of the primary air and the vent gas, plus the availability of sufficient atmospheric air for complete combustion, plus the effect of heated ceramic in the vicinity of the flame, provide means for complete combustion of the vented gases with low emission of smoke and light.
摘要:
A bio-absorbable cartilage repair system is provided for regenerating damaged or destroyed articular cartilage on a joint surface of a bone by establishing a chondrogenic growth-supporting matrix between an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and subchondral cancellous bone. The system is an assembly of a delivery unit and a porous insert. The delivery unit is formed of bio-absorbable material and configured and dimensioned to be mounted in both an area of damaged or destroyed articular cartilage that has been removed and an adjacent healthy area of articular cartilage and cancellous bone. The delivery unit has a central body and a plurality of radially extending, flexible support arms projecting outwardly from the central body and configured and dimensioned to support the insert at least partially thereover. The insert is supported by the delivery unit, formed of bio-absorbable material, and establishes communication between the removed area and the adjacent healthy area for a chondrogenic growth-supporting matrix.
摘要:
Disclosed is a method for controlling phytopathogenic fungi using pure strains of Rosellinia subiculata ATCC 74386 and fungus ATCC 74387. Further, methods of producing a sordarin compound are disclosed. The method includes cultivating each strain separately in a nutrient medium containing assimilable sources of carbon and nitrogen and recovering the compound. A sordarin compound of formula I is also disclosed. Also an antifungal composition containing a sordarin compound is also disclosed.
