Patent number: 10988861Abstract: An apparatus for continuously making a spunbond web of filaments comprises a spinneret, a cooling chamber into which process air for can be introduced for the purpose of cooling the filaments, a monomer suction device between a spinneret and cooling chamber, a stretcher and a deposition device for depositing the filaments of the spunbond web. The cooling chamber is divided into two cooling compartments, and process air can be suctioned out from a first upper cooling compartment at a volumetric flow rate (VM) to a monomer suction device. Process air exits from the first upper cooling compartment at a volumetric flow rate (V1) into a second lower cooling compartment and from the first upper cooling compartment at a volumetric flow rate (V1) into a second lower cooling compartment. A ratio (VM/V1) is 0.1 to 0.35.Type: GrantFiled: August 16, 2019Date of Patent: April 27, 2021Assignee: REFENHAEUSER GMBH & CO.

Patent number: 6582690Abstract: The invention concerns a cytotoxic, MDR-associated substance for producing a therapeutic agent for tumor therapy, which is characterized by a) the tumor cells of a tumor patient are chemosensitized with a cytokine, b) the scope of expression of one or more MDR-associate genes (e.g. mdrl, Mrp, Lrp) in the tumor tissues of the patient is determined according to the beginning of the cytokine treatment, c) the time domain is determined, in which the expression of one or more MDR-associate genes is substantially reduced by the cytokine treatment, d) the patient is treated in the determined time domain (“therapeutic window”) with a therapeutically effective amount of a cytotoxic, MDR-associated substance, the effectiveness of which is influenced (enhanced) by the expression of one or more MDR-associate genes. The use of said substance leads to an improved tumor therapy.Type: GrantFiled: March 19, 1999Date of Patent: June 24, 2003Assignee: Max-Delbrück-Centrum für Molekulare MedizinInventors: Ulrike Stein, Wolfgang Walther, Peter Schlag
