Abstract: Proposed is a line assembly (1), including: a metal hose (2) that is corrugated at least in some segments; and an inner component (3), which is arranged radially inside the metal hose at least over a partial length of the metal hose; the line assembly being distinguished by at least one coupling element (4, 4?), which coupling element is arranged between an outer border (2d) of the metal hose (2) and an outside surface (3a) of the inner component (3) and which coupling element is designed to damp the metal hose (2) by means of mechanical coupling to the inner component (3).

Abstract: A duct element for the exhaust system of a motor vehicle with an internal combustion engine, including at least one flexible duct part, preferably a bellows. The flexible duct part is embodied at least partially from a first type of steel with a Mo-content ?4% or ?6% and with a N-content from 0.3% to 0.6% or from 0.18% to 0.25%, preferably embodied from steel of the type 1.4565 or the type 1.4547. Furthermore a decoupling element is provided for motor vehicles with an internal combustion engine and a respective use of steel embodied with a Mo-content ?4% or ?6% and a N-content from 0.3% to 0.6% or from 0.18% to 0.25%, preferably steel of the type 1.4565 or 1.4547.

Abstract: A line is provided for hot gas, for the use particularly in a motor vehicle with an internal combustion engine, with the line including at least one guiding pipe (2), having deformations (4) over at least a portion of its length at least over parts of its circumference, which seen from an exterior of the guiding pipe (2) are embodied convexly or concavely and are interrupted at least once in the circumferential direction.

Abstract: A heat exchanger for swimming pools, formed of an essentially cylindrical housing through which a first medium flows axially, while a second medium flows through a conduit that is installed in the housing and that is fashioned as a coil. The coil-shaped conduit is formed of a corrugated hose, and has separate connections for the second medium, or for the corrugated hose. The corrugated hose is connected at its end segments to separate connections for the second medium via a plug connection. The connections extend from the outside to the inside of the housing, passing through the housing.

Abstract: A flexible conduit element that is made out of an annular corrugated tube or an annular corrugated pipe and is provided with a connection device. The connection device 6 is located on one end of the flexible conduit element and includes a joining piece 2 that has an external threading 5 and is placed on the end of the flexible conduit element 1. A union nut 3 can be shoved onto the flexible conduit element 1 and screwed onto the outer threading 5 of the joining piece 2, and a clamping ring 4 that can be shoved onto the flexible conduit element 1, is arranged between and deformed by the joining piece 2 and the union nut 3.

Abstract: A heat exchanger for swimming pools, formed of generally cylindrical housing, through which flows a first medium while a second medium flows through a line designed as a spiral within the housing. The spiral shaped line is formed of a corrugated hose and possesses separate connection fittings for the second medium, namely the corrugated hose. The corrugated hose is connected by its end sections which extend in an axial direction to likewise axially extending sections of the separate connection fittings for the second medium.

Abstract: A stepping motor of the homopolar design with a step angle of 3.6.degree. and having a generally cubic form is disclosed. The motor includes a generally square, single-section laminated stator which has only four stator poles extending radially inwardly from the middle regions of the straight sides, and a concentric rotor secured to a shaft journaled in a pair of bearing bells fixed to the stator at the opposite faces thereof and having the same generally square configuration. The rotor includes a disc-shaped permanent magnet of high remanent energy density (B.times.H).sub.max .gtoreq.10.times.10.sup.6 GOe, and a pair of annular steel rotor elements provided at the working air gap with identical numbers Z.sub.r of rotor teeth of pitch .tau..sub.r =360.degree./Z.sub.r. Each stator pole is provided at the working air gap with four or five stator pole teeth of pitch .tau..sub.s =360.degree./Z.sub.s, where Z.sub.
