Abstract: A vibrating abrasive container is formed with track-line which lies in a plane running at an acute angle to the horizontal and therefore at an acute angle to the vertical axis of the vibration generator, in such a manner that the uppermost and lowermost points face each other approximately diametrically, thereby causing a spirally circulating processing movement of the contents of the container to take place on the descending section of the container.

Abstract: Discharge and separating devices of vibratory abrasive containers forming a trough and having a flap for placing into operation a separating path which is coordinated behind the flap, the flap being swingable around the flap shaft axis which is transverse to the container trough and being able to be moved upwardly by means of an actuating device into a maximum upper position. A control lever is operatively connected to the actuating device being pivotally mounted under a portion of flap parallel to the flap shaft, the control lever having a free end formed with a pin. The flap is formed with an elongated slot having an end region, the pin engaging into the slot in the flap and limiting the upward movement of the flap by abutting against the end region of the slot.

Abstract: Workpieces are ground by rolling them around with grinding bodies and microbodies (7) in a vibratory scouring container (1) while a processing liquid is fed into, and runs out again from, the scouring container. The microbodies run out of the container with the processing liquid, are washed and screened in a device (17) to separate those having dimensions less than a predetermined size. The residual larger microbodies are collected in a storage container (8'). The container (8') is subsequently mounted on a post (10) in place of a similar container (8) and the microbodies are returned in controlled amounts into the scouring container by flushing out through a discharge opening (11) with water.

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.
