Abstract: A converter for catalytic conversion of exhaust gas from an internal combustion engine comprising a double-shelled housing, of which the outer shell is spaced apart from the inner shell. The two shells are slidable with respect to one another and have a heat-retaining layer disposed there-between. The housing is provided with a gas inlet and gas outlet. Slidably mounted in the interior of the housing is at least one receptacle which has exhaust gas passage ways disposed in its upper and lower end portions. The receptacle(s) is (are) filled with granular catalyst forming a bed.

Abstract: 1355990 Biologically purifying effluents KNAPSACK AG 16 Nov 1971 [5 Dec 1970] 53134/71 Heading C1C [Also in Divisions B1 and G1] The escape of foam from a closed reactor 1 having a mechanical defoaming means 7 therein is inhibited by continuously regulating within a predetermined range the foam pressure prevailing above the liquid phase, by modifying the level of the liquid phase between upper and lower levels 10, 11 through automatic adjustment of the valves 4, 5 controlling the inlet and outlet lines 2, 3 for liquid. The apparatus also includes a gas admission tube 6, a hollow driving shaft 8 of the defoamer 7, which serves as an outlet for gas, and a control system 9 arranged to actuate valves 4, 5 in response to signals from the pressure meter (PC) and level meter (LC). The method is applicable particularly to aerobic fermentation, for example the microbiological purification of effluents, involving intensive foam formation varying at irregular intervals.

Abstract: Device for holding a granular catalyst suitable for use in the decontamination of the exhaust gas of an internal combustion engine. The device comprises a housing which comprises a jacket closed by means of end plates and which is provided with a gas inlet and gas outlet, and which has disposed therein a sleeve having an annular cross-section and having perforated walls, this sleeve being disposed substantially concentrically with respect to the gas inlet. In the device at least one end-plate-facing terminal portion of the sleeve, and also the lateral wall of the sleeve, are slidably mounted relative to the jacket of the housing, so as to accommodate axial relative movements.
