4686202 ~R~~A~T~UN OF CATALYSTS FOR THE DETOXIFICATION OF WASTE GASES Franz J Broecker, L~d~gshafen, Federal Republic Of Germany assigned to BASF Aktienge~llschaft Catalysts, in particular for the detoxification of automobile exhaust gases, are prepared by a process in which the active components and the promoters are applied onto a carrier by vapor deposition under very greatly reduced pressure. The carriers nsed are advantageously in the form of nets or woven fabrics. The catalyst fabrics coated by vapor deposition are pressed together to form catalyst packets for installation in the reactor, and the shape of the catalyst packets is adapted to the ffow conditions in the reactor.
HAZARDOUS WASTE REACTOR SYSTEM Terry R Galloway assigned to In-Process Technology Inc A thermal decomposition reactor accepts solid, liquid or gaseous waste products of indust~al processes or the like and rapidly reduces same to substances such as carbon dioxide, water and glassified non-leachable ash without limitation
by materials that may be commonly included in such waste.
4688772 APPARATUS FOR SEALING THE SKIRT OF A C~~ERTER WASTE GAS RECOVERY SYSTEM Toyo-o Murata, Hirosh Narita, Yukinori Shigeyama, Mazumi Nishikawa, Kitakyushu, Japan assigned to Nippon Steel Coloration; Kawasaki Jukogyo Kabushiki Rais An apparatus for sealing the skirt of a converter waste gas recovery system is disclosed, which includes an annular flange that is mounted about the outside surface of the converter adjacent to its mouth at a point clear outside the reach of the molten slag and metal that might spill over the rim of the converter mouth during the process of blowing. An annular sealing band is provided at the lower peripheral portion of the skirt, which runs surrounding the mouth. The annular sealing band is divided into multiple arcuate segments of a whole bandage, each pivotally disposed on a horizontal pin and connected to a separate hydraulic cylinder through its axially movable piston rod. It is so designed that the segments of the annular sealing band are individually yet simultaneously swung about their respective pins by their hydraulic cylinders into abutting contact with the external periphery of the flange providing a tight leakproof seal. In the contacted surfaces of the annular sealing band and the flange, sealing is most unlikely impaired by clumps of solidified slag and metal spilled in molten state from the converter mouth as in the skirts of conventional waste gas recovery systems.
