摘要： A process and an apparatus for making thermoplastic polyurethanes continuously, the apparatus combining a storage tank and dehydrating equipment for a polyol and storage tanks for other components of a polyurethane reaction mixture all connected through conduits to a mixing device which discharges the reaction mixture continuously over the surface of a conveyor belt. The conveyor belt is provided with means for controlling the temperature thereof. The solidified thermoplastic product discharged from the belt is continuously granulated and conveyed to containers.

摘要： A sealing device for sealing at least two facing surfaces of two adjacent machine elements includes an inflatable sealing tube arranged in a groove in a first surface of a first machine element. The sealing tube can be filled with a medium to which pressure can be applied, and can be inflated by the medium as well as made to rest against a second surface of a second machine element, forming a seal. The ends of the sealing tube are each arranged in an insert piece. The insert pieces are each structured as a sleeve and surround the ends of the sealing tube under elastic pre-stress, forming a seal. The sleeves are each arranged in a recess of the first machine element that extends essentially crosswise to the lengthwise direction of the groove. In the non-pressurized state, the sealing tube and the face of the sleeves that faces the second surface of the second machine element are essentially flush with the first surface of the first machine element.

摘要： A device for sealing a gap between two members. The device comprises at least one elastically expanding hose accommodated in a groove (2) in the wall of the gap. The hose can be expanded by a compressible fluid introduced through a rigid opening such that the hose cannot be displaced in relation to the opening. To provide a device that is easy to install and remove and that requires no straps to secure it, the hose (1) is inserted into the opening (3) and has one end loose and the other end secured by supports.

摘要： A method of producing inside linings with a skin of polyurethane material and a polyurethane support reinforced with fiberglass pour-behind foamed together in a mold. The method operates in such a fashion that the support is first produced separately from a fiberglass mat, cut to size with exact contours and dimensions relative to the finished inside lining, and saturated with polyurethane material to form a support with a protruding edge section consisting only of the polyurethane material. The polyurethane skin is inserted into a lower mold with an edge that protrudes in the separation plane of the lower mold. The separately produced polyurethane support is then inserted into the upper mold with the edge section, made only of polyurethane material, lying in the separation plane. The support and the skin are pour-behind foamed by filling the polyurethane material into the open mold. The mold is closed so that the edge section of the separately produced support in the separation plane contacts the skin and forms a seal. The mold is then opened, and the molding is taken out. If one works with a closed mold, the mold naturally is first closed; and the polyurethane material is filled into the closed mold. The edge section consisting only of polyurethane material is cut off from the end product so that the waste consists solely of recyclable polyurethane material. At the same time, the edge section forms a seal during pour-behind foaming, which prevents the polyurethane material from reaching the outside surface of the skin during pour-behind foaming.
