Abstract: A pump for conveying a fluid includes a casing with a casing inner wall, a pump interior, an inlet opening, an outlet opening, a displacement assembly, and a radial protective element arranged in the pump interior in order to line at least one radial section of the pump interior, the radial protective element bearing against a radial section of the casing inner wall. A fastening element is provided which can be arranged in a fastening position in which the fastening element bears against an edge of the radial protective element and in the process fastens the radial protective element in the pump interior, wherein the fastening element has a longitudinal extent which extends from a first axial end of the pump interior along a recess arranged in the casing inner wall.

Abstract: Mine dust in underground coal mines is potentially explosive and must be sampled and tested for sufficient inert content regularly. The present invention comprises a pneumatic mine dust sampling instrument equipped with a specially designed nozzle arrangement that delivers a controlled pulse of air which entrains the mine dust, similar to the entrainment process that happens during a mine explosion. The entrained mine dust can then be collected and tested for compliance with applicable federal standards.

Abstract: Motor vehicle components, such as doors, trunks, bumpers, instrument panels at dash boards, top or shelf panels of dash boards, or horizontal storage panels behind rear seats, which include a plastic foam body.

Abstract: A composite material constituting foam particles and fibers, comminuted materials, or a combination thereof. They composite material may be manufactured by mixing the components prior to molding or mixing the components as they introduced into the mold. Heat may be used to weld the components together to form the composite material. Additionally, the composite material may also include reinforcement agents, adhesive agents, films or combinations thereof.

Abstract: The invention relates to a method for producing plastic hollow bodies which are filled, at least partially, with foam particles. The plastic hollow body is produced by rotational moulding and is filled, at least partially, in the rotational mould with foam particles. Foam particles which are made of the same type of a polyolefinic plastic material, from which the wall of the hollow body is also made, are used in order to simplify the recycling.

Abstract: According to the invention, the production of plastic foam products consisting of beads comprises the molding of pimples in an automatic molding machine. Said pimples reduce the noise that is produced when the product is subjected to friction.

Abstract: In order to facilitate the recycling of plastic composite materials and moldings produced thereof, the invention relates to a single-sort, mono-material composite material, comprising a core of thermoplastic foam and at least one reinforcing layer made of a composite consisting of fibers or strips of the same thermoplastic material as the foam. The invention further relates to a method for producing said single-sort composite material, during which the foam made of thermoplastic material is applied onto a pre-formed reinforcing layer and is welded there to each other and to the reinforcing layer by adding heat, a composite consisting of at least two layers of fabrics, knitted fabrics or non-wovens of fibers or strips made of the same thermoplastic material as the foam being used as reinforcing layer.

Abstract: The invention relates to a form tool for producing particle foam molded parts having at least one tool part consisting of a finite number of layers which are parallel to each other, at least in segments, in which the individual layers have contours such that a stack formed by the totality of all layers defines at least one part of a form cavity which can be filled with expandable beads of a thermoplastic material, and having means for supplying and discharging gaseous and liquid heat transfer media.

Abstract: There is now provided a motor vehicle dashboard for a motor vehicle. The motor vehicle dashboard has a frame structure that can be attached to a motor vehicle body. The dashboard has a first element with a first attachment side and a second attachment side opposite the first attachment side, with the first attachment side of the first element being configured to be adhered to the frame structure. The first element comprises foam. The dashboard has a second element with a first side that is configured to be exposed towards the interior of a motor vehicle, and a second, attachment, side opposite the first side of the second element. The first side of the second element provides a leather-like appearance to the dashboard. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.

Abstract: There is now provided a method for producing a product comprising plastic foam in an automatic molding machine. The method comprises providing a woven fabric on at least one surface of the mold cavity, with the woven fabric comprising a fabric having a fine-mesh woven fabric ply that faces the interior of the mold cavity upon assembly and a coarse-mesh woven fabric ply that is disposed adjacent at least one surface of the mold cavity and beneath the fine-mesh woven ply upon assembly to support the fine-mesh woven ply. The method further provides for introducing beads comprising plastic foam into the mold cavity; contacting the beads with a gaseous heat transfer medium, such as superheated steam; introducing the gaseous heat transfer medium into the mold cavity; flowing the gaseous heat transfer medium along a first surface of the mold cavity; and removing gaseous heat transfer medium along a second surface of the mold cavity; and removing the finished product from the mold.
