    摘要: An apparatus for evacuating and sealing rectangular packages includes a turntable, a plurality of vacuum hoods arranged circumferentially on the turntable and having an open position in which a package to be evacuated and sealed is received and a sealed, closed position. There is provided a package-engaging surface on each hood on its inside and an abutting mechanism arranged on the turntable below each vacuum hood. Each abutting mechanism also has a package-engaging surface. The abutting mechanism is arranged for radially outward movement for displacing, with its package-engaging surface, a package towards the package-engaging surface of the vacuum hood. In the closed position of the vacuum hood the package thereunder is engaged at opposite sides by the two surfaces.

    摘要: In a planetary extruder for extruding thermoplastics materials, a threaded main spindle is meshed with and surrounded by threaded planetary spindle. To improve pull-in of material, the planetary spindles are provided in groups, each group comprising at least three spindles. The first planetary spindle of each group corresponds in length to the main spindle and succeeding spindles, considered in an opposite direction to the direction or orbital movement of the planetary spindles, of each group are each shorter than the spindle which immediately precedes it to form receiving spaces for material fed by a feed screw, which receiving spaces in operation are continuously enlarging.In one embodiment in each group, the spindles which are successively shorter are followed by spindles which are successively longer.

    摘要: A module for a tester for the testing of circuit boards is described. Such testers have a basic grid on which an adapter and/or a translator may be arranged in order to connect contact points of the basic grid with circuit board test points of a circuit board to be tested. The module comprises a support plate and a contact board. The contact board is formed by a rigid circuit board section which is described as the basic grid element, and at least one flexible circuit board section. Provided on the basic grid element are contact points which each form part of the contact points of the basic grid. The basic grid element is mounted at an end face of the support plate, and the flexible circuit board section is bent in such a way that at least part of the other section of the contact board is parallel to the support plate. Each of the contact points of the basic grid element is in electrical contact with conductor paths running in the contact board and extending from the basic grid element into the flexible circuit board section.
