  • Publication number: 20030007906
    Abstract: A catalyst carrier body includes a honeycomb body having sheet-metal layers and an axial extent. The sheet-metal layers are at least partly structured in such a way that the honeycomb body has passages through which an exhaust gas can flow. The sheet-metal layers of the honeycomb body have end regions lying radially outwardly. A tubular jacket has an edge and an axial span shorter than the axial extent of the honeycomb body. The tubular jacket is connected to the honeycomb body in at least one axial partial-region by a joining technique. A sleeve has an axial length shorter than the axial extent of the honeycomb body and is disposed on an outer region of the honeycomb body, in the vicinity of an end surface. The sleeve has an inner shell surface connected by a joining technique to the end regions of the sheet-metal layers at the end surfaces. The honeycomb body projects beyond an edge of the tubular jacket in a projecting section surrounded by the sleeve.

  • Publication number: 20020167195
    Abstract: The invention relates to a door module (1) for motor vehicles and the manufacture of such a module. The invention is characterized in that the door module (1) is intended for fixation to a door (2) of a motor vehicle and has a synthetic material carrier (1a) as a carrier element, and various function elements and/or reinforcements (11) fixed by synthetic material injection-moulding or connected to the synthetic material carrier (1a) by means of injection-moulded synthetic material.

  • Patent number: 6296922
    Abstract: An assembly having a system for preventing mechanical vibration includes a honeycomb body disposed in the interior of a tubular casing for permitting a fluid flow therethrough. The tubular casing has at least one reinforcing structure which locally increases vibration resistance and is connected to the honeycomb body only in at least one partial region of its inner surface at least in a surrounding region of the reinforcing structure only over a part of the inner periphery. The reinforcing structure projects from the outer surface of the tubular casing by more than the thickness of the tubular casing. The system according to the invention enhances both the durability of a honeycomb body as well as its connection to a tubular casing.

  • Patent number: 5762651
    Abstract: To prevent dusting of a solid such as a crop protection agent, a pharmaceutical or a dyestuff, there is added thereto as a dustproofing agent a compound of the formula I ##STR1## in which Z represents Z.sub.1 or Z.sub.2 whereZ.sub.1 denotes a bivalent radical of the formula ##STR2## in which W represents a direct bond or a C.sub.1 -C.sub.3 unit, andZ.sub.2 represents unsubstituted arylenedioxy, wherein the remaining variables are defined herein.

  • Patent number: 5749800
    Abstract: A synchronous belt drive, with a high multiplication ratio for transforming a rotary movement into a translation or rotary movement, has at least two rows of teeth with different pitches interconnected by a toothed belt. The rows of teeth with different pitches engage wheels of at least one pair of wheels secured against independent rotation. The products of the number of teeth of the wheels and the pitch of the corresponding row of teeth differ at least slightly from each other. The pitch difference between the toothed belts gives the drive a high multiplication ratio. Very fine gradations and therefore high multiplication ratios may be achieved, even when the tooth modulus is high for reasons of resistance.
