摘要:
Method for producing a card sliver and carding machine therefor. The flexible bend of a card is set automatically by the machine control by means of a controllable actuator system on the basis of a wear characteristic, this characteristic representing the wear as a function of the production of a given material.

The invention describes the development of a new buffer system for cell culture media for establishing a CO2 regulation in the bioreactor with eukaryotic cells. This technology makes it possible to obtain CO2 regulation for process control, process optimization and scaling. In addition, the invention describes a specific cell culture medium with specific buffer substances.

The invention relates to fastening means (in particular to so called clothing clips) for the fastening of clothing strips on flat rods, made of light metal or light metal alloys. Thereby the fastening means are laid-out in such a manner that, when the flat rods assume their operating temperature, these are not deformed.
摘要:
A grinding device for the flats of a card comprises elastically bendable elements which enter between the clothing points, brush over the side flanks of the points and thereby grind the points. Additional grinding elements are provided in order to treat the front sides of the clothing points. The ground-off material may be removed by a suction device.

In a fiber processing machine with a separating edge in which fibers as well as air are guided in a substantially predetermined transporting direction past the edge, trash particles are selectively removed from the fiber/air stream with the help of the edge. The adjustment of a separating element, in particular, the setting of the angular position of a separating surface and/or the penetration depth upstream from the separating surface is linked with an adaptation of the width of the eliminating gap. Also, at least one measure can be taken for eliminating, as far as possible, a pressure drop and/or air turbulences downstream (in the transporting direction) from the edge. Downstream from the edge, a flow pattern as laminar as possible is generated or maintained, respectively.

A grinding apparatus for the flats of a card comprises elastically bendable elements which penetrate between the points of the flat clothing sweep along the lateral flanks of the flat clothing wires and grind the points in the process.
摘要:
In order to grind clothing of a carding element, such as a cylinder of a textile machine, such as a card, during operation of the cylinder, a slide is moved back-and-forth across the clothing. The slide is reciprocated back-and-forth by an inner run of a drive belt guided in guides such that the drive belt together with a grinding element, like a grinding stone, closes a housing totally covering the arrangement. As a result, neither grinding dust nor fibers can enter the housing. Each time the grinding stone moves past a grinding member, such as a diamond rake or diamond roller this grinding stone is re-ground, so that the clothing is maintained sharpened by the continuous grinding operation and the grinding stone itself is cleaned or re-ground by the grinding member. Also, structure detects the degree of wear of the grinding element so that upon reaching a predetermined value such grinding element can be replaced.
