Abstract: A filter cartridge has a frame made of tough material, which sealingly surrounds an accordion fold pack on its circumferential side. The frame is made of assemblable, plate-shaped frame elements and has, on the circumferential side along the lower and/or upper edge of the frame, a tongue, the tongue being insertable in a latticed holder having a U-shaped profile. A viscous joining compound is used to affix the tongue in place. The tongue is formed by strip-shaped tongue elements, each tongue element being joined to a frame element, wherein the adjacent ends of the tongue elements are sealingly fastened to each other by connecting corner pieces.

Abstract: Copolymer DMC-catalyzed polyoxypropylene polyols which exhibit processing latitude similar to base-catalyzed copolymer analogs and homopolyoxypropylene analogs may be prepared by oxyalkylation with a mixture of propylene oxide and ethylene oxide such that a finite ethylene oxide content is maintained in the oxyalkylation reactor for the most substantial part of the oxyalkylation, the polyoxypropylene polyol having randomly distributed oxyethylene moieties which constitute 1.5 weight percent or more of the polyol product. Block copolymer polyols having external blocks containing lesser oxyethylene content than internal blocks and bicompositional compositions containing discrete multimodal and dissimilar and optionally multimodal polyols produced by a continuous addition of starter process are useful as polyols exhibiting greater processing latitude.

Abstract: In a pressure sensor, the force is introduced onto a piezoresistive measuring element via a diaphragm and a punch. Since no exact mechanical adjustment between the diaphragm and the measuring element is necessary, various relatively inexpensive forms of diaphragm with different measuring sensitivity can be used. The punch and the piezoresistive measuring element can be pushed through an opening in the housing and pressed onto the diaphragm so as to provide an interlocking frictional connection between the punch and the measuring element.
