Abstract: A coupling which can be used in fueling lines (L1, L2) or the like, the coupling having a closure device which blocks the flow path of the fluid and are brought automatically into closed position as a function of a sensor-recorded displacement of the feed line with respect to the discharge line; in order to achieve a functionally optimized solution, the coupling is developed as rapid-closure coupling (K) having an ejector ram (41) acted on by pressure fluid as a result of the action of a sensor, for the separation of the two coupling halves (I, II) which have previously been brought individually into the closed position (closing of the shut-off valves V1, V2), also due to the action of a sensor.

Abstract: The present invention relates to a centrifugal-force vibratory grinding machine having a container (3) which receives filling material consisting of workpieces and work bodies and the bottom (4) of which rotates relative to the container wall (5) around the axis of the container and leaves a separating gap (7) towards the container wall (5), and it proposes, in order to reduce the wear within the region of the separating gap (7), that at least one discharge element (A) is provided for the removal of particles of filling material which have penetrated into the space of the gap, which element engages into the space of the gap and rotates with the bottom (4) and/or is stationary with respect to the container wall (5).

Abstract: A channel formed vibration abrasive container with a channel surrounding, in a non-circular longitudinal course, a centrally disposed vibration generator, to which channel there is coordinated a selectively operative discharge- and separation- device. The channel course comprises two 180.degree. curved arcs disposed opposite each other at a distance, which arcs are arranged in symmetrical position relative to the vibration generator and are connected with each other by two parallel extending linear channel sections.

Abstract: A vibratory apparatus for the surface treatment of parts with media in which the apparatus includes a generator for inducing supplementary vibrations superimposed upon the basic vibrations, in which the generator is in the form of a free oscillatory means of a bowl housed within a race for circular movement about an axis parallel with the axis of the means inducing the basic vibrations.
