Abstract: According to a process for recovering reusable gas from waste through pyrolysis, the previously comminuted waste is transformed into fluff, granulates or pellets and introduced into a degassing drum (16), in which low temperature carbonization gas is generated and separated from the residual matter. The low temperature carbonization gas is decomposed into combustion gas in a gas converter (19) and cleaned in a subsequent gas washing installation (21-24 and 47-51) with circulating washing water. Part of the water of the circulation system of washing water is withdrawn and replaced with fresh water in order to limit its concentration of toxic substances. The pyrolysis residues to be withdrawn from the low temperature carbonization drum are withdrawn through a water bath (72). At least part of the quantity of liquid withdrawn from the circulation system of washing water of the gas washing installation (21-24) is introduced in the water bath (72).

Title: Inhibin containing compositions and methods of applying them
Inventor: FIORETTI WILLIAM C
IPC: A61K38/07
Filed: 1995-02-28
Abstract: The present invention relates to a method of accelerating the onset of puberty in avians, especially ratites and psittaciformes, by administering a heterologous protein comprising inhibin, or a fragment thereof, and a carrier protein. The present invention also relates to a method of increasing egg production in animals, particularly birds, more particularly ratites, via the administration of the heterologous protein. This invention further relates to the heterologous protein and a method for producing the heterologous protein. The heterologous protein can be either inhibin conjugated to the carrier protein or inhibin fused to the carrier protein. The method of producing the fused heterologous protein comprises inserting double stranded cDNA encoding inhibin, or a fragment thereof, into a vector which encodes a carrier protein such as maltose binding protein or bovine serum albumin. After inserting the vector into an expression system, the fused heterologous protein is expressed by the system. After purifying the expressed heterologous protein, an effective amount of the protein is administered to an animal such that an immunological response occurs in the animal against the heterologous protein.

Abstract: A fibreboard (4) formed by dry forming of a fibrous tissue (2) in a forming box (6) with subsequent heat treatment in an oven, wherein the fibres are selected from synthetic fibres, natural fibres or a mixture thereof, and wherein the fibreboard (4) is provided with rupture zones (30). The invention also relates to a forming box (6) for use in the manufacture of fibreboards (4), wherein the forming box (6) is arranged above a forming wire (14) which extends across a vacuum box (20). The object of the invention is to introduce rupture zones (30) in fibreboards (4) which are formed directly in the forming process, and that the gap (36) of the rupture zone is formed without the use of cutting tools. Hereby, fibreboards (4) can easily be adapted in width and length without the use of tools, while separation of the fibreboard (4) provides a regular rupture face ensuring that no thermal bridge is created at joints. The forming box (6) may be provided with vertical partitions (12) longitudinally of the forming wire (4) and sets of vertical partitions (13) transversely to the forming wire (14). The purpose of the partitions (12, 13) is to enable production of fibreboards (4) with incorporated rupture zones (30) or fibreboards (4) in independent webs/sections (58, 60).

Title: Method for nitro-carburization of metal workpieces
Inventor: SCHMIDT HANS-PETER
IPC: C23C8/30
Filed: 2000-08-04
Abstract: The invention relates to a known method for nitro-carburization of metal workpieces, whereby the workpieces are treated in a treatment chamber with a treatment atmosphere containing nitrogen, carbon monoxide and hydrogen at treatment temperature, whereby carbon dioxide is used as carbon contributor to generate the treatment atmosphere. The invention aims at modifying said method so as to be able to regulate as much as possible the type and volume of nitride formation. To this end, a gas flow (1; 21) containing carbon dioxide is introduced into a reactor (4; 24) connected upstream from the treatment chamber (6; 27) and modified therein into a carburizing gas (5; 25) by reaction with a hydrogen contributor (2; 22) at a reaction temperature above treatment temperature, said gas having a higher carbon activity at treatment temperature than the gas flow (1; 21) containing carbon dioxide.
