Abstract: Disclosed is a hollow fiber system for a humidifier, including hollow fibers that are permeable to steam. A first air flow can be conducted within the hollow fibers while a second air flow can be conducted outside the hollow fibers. The hollow fibers are located at least in part at a distance from each other via a device (6) that is disposed between the hollow fibers, respectively.
Abstract: A squeezing device for a wiping cover of a flat-body wiper, the wiper cover hanging downward and partially detached from a wiper plate of the flat-body wiper in a vertical position of the wiper plate, the wiper plate including a downward facing pressure surface in the vertical position. The squeezing device includes a funnel-shaped squeezing shaft having a counterpressure surface in a lower region of the squeezing shaft. The squeezing shaft is configured to receive the wiper cover and at least a portion of the wiper plate in the vertical position of the wiper plate so that a squeezing pressure of the pressure surface against the counterpressure surface squeezes out the wiper cover. The squeezing shaft includes stabilizing devices configured to stabilize the wiper plate against tipping relative to a first plane from the vertical position. In addition a cleaning system including the squeezing device and a method of squeezing a wiping cover of a flat-body wiper with the squeezing device.
Abstract: A method for production of a reactive polyurethane emulsion for use in impregnating and coating a textile fabric includes reacting polyols alone or in combination with at least one of diols and triols with a substoichiometric amount of diisocyanates so as to form medium-viscosity, OH-terminated prepolymers. The prepolymers are mixed with an external emulsifier. At least one of a diisocyanate, a triisocyanate and a polyisocyanate are added so as to bring about a crosslinking of the prepolymers.

Abstract: A tube seal is provided including a rigid cylindrical tube and an elastomeric seal body molded to the outer surface of the cylindrical tube. The rigid cylindrical tube includes a recessed annular groove at each end thereof for receiving the elastomeric seal body therein to create a mechanical connection to resist the seal body from being pulled away from the cylindrical tube. The tube seal is also incorporated into a diameter reducing tube seal, an integrated tube seal and filter design and an integrated tube seal and valve design.
Abstract: A thermally fusible interlining nonwoven includes a fusing layer (A) having at least one staple fiber nonwoven containing at least 50% by weight of thermoplastic staple fibers having at least one of a melting or softening temperature in a range from 60° C. to 165° C. A layer (B) is bonded together with layer (A) and includes at least one staple fiber nonwoven or a staple fiber nonwoven fabric having staple fibers. At least 80% by weight of the staple fibers of layer (B) have at least one of a softening temperature, melting temperature and degradation temperature that is higher than or equal to 170° C.

Abstract: An arrangement consisting of a cover and a filter element, wherein the filter element has a corrugated bellows with adjacent pleat ridges, wherein the corrugated bellows is hemmed by edge strips, wherein the filter element bears against one abutment side of the cover forming a seal and wherein the filter element is fixed with one side to the abutment side and in that context projects self-supporting from the abutment side of the cover, is in view of the objective to design an arrangement of the type mentioned at the outset and develop it further so that following cost-effective production, a reliable attachment of a filter element on the cover is assured, characterized in that gripping means are arranged on the abutment side which engage around an edge strip on both sides, which bears against the abutment side.
Abstract: A piston accumulator includes a housing having a housing wall and a piston disposed in the housing. The housing wall and the piston form a pressure chamber. The piston is slidably moveable along the housing wall so as to change a volume of the pressure chamber. A slide layer disposed on at least one of the piston and the housing wall is configured to guide the piston free of guide rings.
Abstract: A method for the production of a seal includes producing a support part, providing a complete coating over the support part, producing a sealing element separate from the production of the support part and adhesively bonding the support part and the sealing element so as to form a unit.
