Abstract: A table arrangement has a mounting element to be fastened to a fastening structure element. A first table element is connected to the mounting element, pivotally relative to the mounting element about a first pivot axis between a stowage position, in which the first table element extends substantially parallel to a mounting plane defined by the mounting element, and a position of use, in which the first table element extends substantially perpendicular to the mounting plane. A second table element is connected to the first table element substantially parallel to the first table element and rotatable relative to the first table element about a rotation axis that is parallel to the mounting plane in the position of use.

Abstract: A screw-type extruding machine includes a housing; a driveable shaft disposed inside the housing and including a rotational moment transfer element; and at least one screw element. The screw element has two ends and defines a longitudinal groove therein for receiving the rotational moment transfer element of the shaft, the shaft thereby transferring its rotational moment to the screw element. The groove is configured such that it defines two expansion regions, each expansion region having an axial extent, the groove having side surfaces which diverge with respect to a longitudinal axis of the groove along the axial extent of each expansion region in a direction toward a corresponding one of the two ends of the screw elements, a width of the groove thereby increasing in a direction toward its two ends along each expansion region.

Abstract: A twin screw extruder for processing plastic material having a housing provided with a plurality of juxtaposed housing segments arranged axially in succession and defining two longitudinal, overlapping bores respectively containing two coaxially arranged extruder screws, rotatable about respective longitudinal axes, and having intermeshing threads. One of the housing segments serves as a degassing housing segment for degassing the plastic material and it is connected to a degassing chamber. The degassing housing segment has a transverse, radial opening in which an insert member is fitted, the insert member having a degassing opening providing communication between the degassing chamber and the bores in the housing. The degassing opening tapers in widening fashion in the direction from the longitudinal bores to the degassing chamber, and the degassing opening has a longitudinal axis disposed in a plane passing through the longitudinal axes of the screws.
