摘要:
A bearing, including a bearing part, in particular a bearing ring (5, 6) having a cathodic corrosion prevention device. The aim of providing a bearing having a permanent, adjustable corrosion prevention device that requires only minor structural changes is achieved according to the invention in that the bearing part, in particular the bearing ring (5, 6), is connected as the cathode of an external power source, and that the anode (8, 10) of the external power source is arranged spaced apart from the bearing part, in particular the bearing ring (5, 6).

The invention provides a needle bearing which has an extraordinarily large number of contact points and allows a long life to be expected even in a corrosive and/or hydrogen-containing working atmosphere. This is achieved by means of a needle bearing which has a bearing ring with a hardened austenitic steel which has a total carbon and nitrogen content of from 0.8 to 1.2% by weight and needles which roll on a bearing surface of the bearing ring and are composed of a ceramic whose surface defects are smaller than 40 μm.

The invention provides a novel filter press comprising: a support frame; a plurality of filter plates mounted adjacent one another on the support frame, the filter plates being displaceable between an inoperative position wherein adjacent filter plates are spaced apart, and an operative position wherein adjacent filter plates abut to form filtration cavities between abutting filter plates; a backing arrangement located adjacent an outermost filter plate, the backing arrangement being displaceable relative to the support frame and being releasably lockable in a fixed position relative to the support frame; and a pressure exerting mechanism adapted to force the filter plates in co-operation with the backing arrangement into sealing abutment when the filter plates are in an operative position and the backing arrangement is releasably locked relative to the support frame.

摘要:
A method for producing an active substance-containing polyurethane plaster for transdermal application is described, said plaster containing at least one active substance at a highly accurate declared dose. In the described method, a solvent-free active substance-containing polyurethane is produced by reactively coating a solvent-free active substance-containing polyurethane material (40), which is mixed in a coating unit (60) immediately before or during the application process, onto an elastic backing foil (20) that has been rendered non-extensible at least in the direction in which the applied polyurethane material is processed by means of a supporting, adhering auxiliary foil (30) which is at least mono-axially non-extensible.

The aim of the method is to achieve a higher penetration depth of the diffusion element coupled with a greater depth of case hardening and a higher case hardening degree, whilst preventing an excessive enrichment of the case, thus obtaining an increased fatigue limit for the component. To achieve this, the full hardening of the component and the plasma-ion hardening of the case of the component are carried out in a common working step. The component is heated to a common hardening and diffusion temperature TH+D lying above the upper transformation temperature AC3, the component being held at the common hardening and diffusion temperature TH+D until the carbon in the component has fully austenitized and dissolved and until the case has been enriched to the desired degree by the diffusion element. The component is then quenched.
