Abstract: A condensing zone is arranged downstream of the front roller pair of a drafting arrangement of a spinning machine, in which condensing zone a drafted roving or a sliver is condensed. The condensing zone has a suction device which has a closed hollow profile and which serves as a sliding surface for a circulating sieve belt. The sieve belt transports the drafted fiber strand to a nipping roller, which presses the fiber strand and the sieve belt against the sliding surface at a nipping point. The fiber strand travels over an essentially in transport direction extending suction slit located in the condensing zone, which suction slit extends to the nipping point.

Abstract: An arrangement for a ring spinning machine for condensing a drafted but untwisted fiber strand includes a drum which transports the fiber strand through a condensing zone. The drum is provided on its outer sleeve with a perforation. In order that the perforation can be particularly fine and close-meshed, the outer sleeve of the drum forms a supporting skeleton, which comprises openings, which are covered over by a thin sieve belt, preferably a woven tape. The sieve belt extends over a suction slit located in the condensing zone. The skeleton is so formed that in the area of nipping points, formed together with the drum, the skeleton is sufficiently resistant.

Abstract: In a method for producing laminate, a buffer layer is applied to a substrate, with the buffer layer material being evaporated from the buffer layer material dispensing devices at an angle &agr;1≠0 at the normal to the substrate surface onto the latter, before an oriented thin layer is evaporated. According to the invention, provision is made such that (a) following evaporation of the buffer layer and prior to the evaporation of the oriented thin layer, at least one cover layer is evaporated under deposition conditions that vary from those under which the buffer layer was applied, especially at a different pressure, different temperature, different rate, and/or different angle &agr;2≠&agr;1, especially &agr;2<&agr;1, preferably &agr;2≈0° to the substrate surface normal, and/or is evaporated on the buffer layer in such fashion that the buffer layer has a biaxial texture and/or facets.

Abstract: A roof rack includes longitudinal members mounted on longitudinal sides of a roof of a vehicle body and is disposed in receiving devices such that the longitudinal members can be moved from a lowered position into an operative position and vice versa. End pieces of the longitudinal members, which rest in spaced receiving devices of the roof, are swivelled, for setting the operative position or the lowered position, outside the receiving devices and about an axis of rotation extending in the longitudinal direction of the vehicle. The end pieces are then inserted again in the receiving devices. Each of the end pieces is releasably connected with a respective longitudinal member.

Abstract: The invention provides a fiber-reinforced composite ceramic containing high-temperature-resistant fibers, in particular fibres based on Si/C/B/N, which are reaction-bonded to a matrix based on Si, which is produced by impregnating fiber bundles of Si/C/B/N fibers with a binder suitable for pyrolysis and solidifying the binder, if desired subsequently conditioning the fiber bundles with an antisilicization layer suitable for pyrolysis, for example phenolic resin or polycarbosilane, subsequently preparing a mixture of fiber bundles, fillers such as SiC and carbon in the form of graphite or carbon black and binders, pressing the mixture to produce a green body and subsequently pyrolysing the latter under reduced pressure or protective gas to produce a porous shaped body which is then infiltrated, preferably under reduced pressure, with a silicon melt.

Abstract: A selecting device facilitates selecting operating positions of an automatic transmission of a motor vehicle by the deflection of a selector lever which moves back automatically from all deflecting directions for selecting the individual operating positions. The automatic transmission can be controlled by this selector lever in a first operating mode—selecting individual driving positions in the automatic operation—or, in a second operating mode—step-by-step shifting of the gears in the manual operation. For each operating mode, one operating position of the automatic transmission respectively is assigned to each deflecting direction of the selector lever. The selector lever is movable, in two shifting channels which are essentially disposed perpendicularly with respect to one another such that maximally four operating positions can be selected in each of the two operating modes. In a third operating mode, cruise control functions can be controlled by means of the selector lever.

Abstract: This invention concerns a two-stroke cycle engine, more specially it concerns a two-stroke cycle engine using a preceding air-layer for scavenging. It has a scavenger passage connected to a branching scavenger passage opened to said scavenging port. The engine has a connecting passage to link the air passage and the fuel passages so that negative pressure in the air passage forces the fuel-air mixture in the fuel passage into said air passage. Further, the engine according to this invention has a removable guide with a surface forming a curved smooth channel which is attachable to the scavenger passage in the crankcase from the mounting surface, and forms a portion of said scavenger passage with the curved channel. The blow-up angle of the scavenger passage varies along the circumferential direction of the cylinder.
