Abstract: The invention relates to a process for the production of catalysts for the reduction of nitrogen oxides from exhaust gases and similar chemical air cleaning processes, in which a catalytically active material is deposited and bonded on a carrier made of metal, preferably stainless steel. The carrier is preferably in the form of a perforated metal plate, or of rib mesh, or a grid, preferably fabric, honeycombed or knitted material made of metal wire, or a similar material with a high specific surface. To simplify manufacturing and to improve the characteristics of the catalysts, the invention proposes the use of an acid which etches the surface of the metal carrier as the binder for the catalytically active material.

Abstract: A structure made from catalyst for use in the separation of nitrogen oxides from combustion exhaust gases which contain dust. The catalytic structure has plates with spaces therebetween to carry a flow of the exhaust gas therethrough. The catalyst is constructed of individual ceramic plates. The abrasion or wear resistance of the plates is chosen such that the dust in the exhaust gases flowing through the spaces abrades the plate surface at a rate which is at least equivalent to the deactivation of the catalyst surface by action of the nitrogen oxides, which constantly provides a fresh catalyst surface for reaction with the nitrogen oxides. The movement of the exhaust gas through the catalytic structure carries the dust and abraded material along with it and out of the structure.

Abstract: An emergency operation ring for tubeless pneumatic tires on motor vehicles made of an elastomeric material and mounted on a rim by means of axial clamping pressure. Two support sections extend diagonally upwards and outwards from the base section and define a circumferential channel. The support sections have step shaped outer flanks set back with respect to the base section. At least one circumferential groove is provided contiguous the circumferential channel, and slipping agent is positioned in the groove or grooves. Sealing lips close off the groove and slipping agent when the tire is intact. The wheel load working on the support sections at the beginning of an emergency operation brings the sealing lips into an open position, whereby the slipping agent is released and lubricates the surfaces of the pneumatic tire and the emergency operation ring in contact with each other.

Abstract: The roller exhibits a support body which is provided with a plurality of support disks. Insulating layers are arranged between the support disks. A heat-resistant cable surrounding the support body in several coils is embedded in each insulating layer. The insulating layer consists of fiber material which is sprayed on at the same time as the cable is wound around the support body. The cable provides a firm and lasting connection of the insulating layer to the support body.
