  • Publication number: 20130028999
    Abstract: A device for continuous production of an extrudate from finely divided plant material and a thermoplastic material. When viewed in an extrusion direction, first the finely divided plant material and then the thermoplastic material are fed to an extrusion device, which can be a twin-screw extruder. The fed-in materials are mixed with one another, degassed and jointly extruded from the extrusion device and thus form the extrudate, and the plant material is embedded in the thermoplastic material, wherein the plant material and the thermoplastic material are fed into the extrusion device at a common position or two directly successive positions. The thermoplastic material is plastified in a separate plastifier extruder before being fed into the extrusion device and is fed from the extruder to the extrusion device in a plastified state, and the plant material is then degassed together with the thermoplastic material.

  • Publication number: 20100295207
    Abstract: The invention relates to a process and a device for the continuous production of an extrudate from finely divided plant material and a thermoplastic material, in which, as viewed in the extrusion direction (E), firstly the finely divided plant material and then the thermoplastic material are fed to an extrusion device (1), which is embodied as a twin-screw extruder, the fed-in materials are mixed with one another, degassed and jointly extruded from the extrusion device thus forming the extrudate (6), and the plant material is embedded in the thermoplastic material, wherein the plant material and the thermoplastic material are fed into the extrusion device at a common position or two directly successive positions, the thermoplastic material is plastified in a separate plastifier extruder (4) before being fed into the extrusion device and is fed from said extruder to the extrusion device (1) in a plastified state, and the plant material is then degassed together with the thermoplastic material.

  • Patent number: 6141914
    Abstract: A door panel formed with a throughgoing hole carries adjacent the hole a shaft pivotal about an axis and having radially projecting retaining formations. An assembly body engaging the panel around the hole carries a movable handle. Retaining formations on the body are engageable with the shaft retaining formations in a predetermined angular holding position of the shaft. The body formations are disengaged from the shaft retaining formations in an angularly offset freeing position of the shaft. The shaft formations are cam lobes and the body has an inwardly extending projection formed with a seat snugly receiving the shaft formations in the holding position of the shaft.

  • Patent number: 5906072
    Abstract: A motor-vehicle door has an outer door panel, an annular inner door panel including a front frame member fixed to the outer door panel, a lower frame member fixed to the outer door panel, a separate upper frame member, and a rear frame member fixed to the outer door panel. The front, lower, and rear members together form an opening and the front frame member is formed with a pair of vertically spaced hinge holes each having a horizontal front part and a downwardly and rearwardly inclined rear part. An insert plate carries the upper frame member, fits in the opening, and is provided with hinge lugs engaged in the openings. The insert plate is pivotal about the lugs in the hinge holes between a raised position projecting inward from the door and a lowered position fitting in the opening. Mechanical, electromechanical, and electronic subassemblies are fixed on the insert plate, and fasteners retain the insert plate on the inner door panel in the lowered position of the plate.
