Granted: 2002-02-07
Abstract: The invention relates to a particularly long component (1), with a closed, roughly channel-shaped hollow cross-section, such that said component may support large forces in various directions and is suitable as a support. The component comprises two individual parts (3) and (4), which have two contact patches (2) with each other, running in the longitudinal direction. At least one first part (3) of the both parts thus has a U- or channel-shaped cross section and is in working connection to the second part (4) which closes the first as a form of lid. The first part (3) is a metal profile (5), extrusion-coated on at least one side with a plastic layer (6) which increases the section modulus and is thus multi-layered. Said plastic layer (6) extends to the edges (7) of the first part (3) and forms there a contact patch for the second part (4). The second part (4) is made from plastic and in the working position is welded to the plastic layer (6) at the contact patch. A stiff component (1) is thus produced with a hollow cross-section, making common use of the advantages of metal and plastic.

Abstract: A process is disclosed for incinerating sewage sludge (1). Sewage sludge is dried by a drier (30) heated by means of a heat transfer medium, then incinerated in a furnace, preferably a cycloid furnace. The heat transfer medium is heated during the incineration process and the furnace smoke gas is dedusted and purified. In order to discharge non-contaminated solids, a basic additive (9a, 9b) is fed to the furnace, the smoke gas is subjected to a first dedusting (17) and cooling (13) process, and its heat is again removed by cooling it down to a lower temperature higher than the limit cooling temperature of the smoke gas. Another basic additive (22) is then added to the smoke gas before the smoke gas is dedusted (23) in a filter. The first dedusting process (17) is carried out before heat is removed for drying the sewage sludge.

Inventor: WITZKO RICHARD
IPC: C08J5/18
Filed: 1996-09-19
Granted: 1997-11-13
Abstract: Microporous PTFE (ePTFE) is known to possess certain properties based on which it is excellently suited for specific purposes, for example, the material is air-permeable and water vapor-permeable, but not water-permeable so that it can be used for filter membranes, etc. In order to create additional functions and application possibilities for this material, a material is proposed that consists of a blend of a fluoropolymer and a thermoplastic. The two substances in the material are present as continuous structures, in which at least one of these structures, preferably both structures, are microporous. The two structures are intertwined with each other and form a so-called co-continuous macrostructure.

Granted: 1998-09-03
Abstract: The invention concerns fibre-reinforced composite ceramics with high-temperature fibres, in particular based on Si/C/B/N, which are bound in terms of reaction to an Si-based matrix. These composite ceramics are produced by impregnating bundles of fibrous material comprising Si/C/B/N fibres with a binder which is suitable for pyrolysis and solidifying the binder, the fibrous material bundles then optionally being conditioned with a silicating protective layer suitable for pyrolysis, such as for example phenolic resin or polycarbosilane. Subsequently a mixture of fibrous material bundles, fillers, such as for example SiC and carbon in the form of graphite or carbon black, and binders is produced. The mixture is then compacted to form a green compact which is then pyrolysed under vacuum or protective gas in order to produce a porous shaped body which is then infiltrated, preferably under vacuum, with molten silicon. In this way, fibre-reinforced composite ceramics which have greatly improved properties with respect to conventional composite ceramics and are in particular suitable for use in heavy-duty braking systems can be produced in an efficient manner suitable for production on an industrial scale.
