Abstract: The invention concerns a rotary belt tool for surface working which is much more versatile and effective than known tools but is nevertheless easy to handle, durable, safe, easily maintained, as well as compact and economical. The belt of the tool is designed as an endless, narrow closed ring to which are attached radial external elements such as bristles, teeth, abrasive grain, or burnishing compounds. The belt is attached along its entire periphery to the periphery of the axial surface shell of a single belt carrier which can rotate. The tool, for example for structuring wood, finishing leather, or derusting steel profiles, can be designed as a wire brush, in which the bristles which extends radially outward from the tool axis as the axis of rotation can be attached, for example, in an equally spaced non-rotatable manner to their main bristle axis such that bristles positioned one behind the other in the peripheral direction are laterally offset to one another in the axial direction and the end regions of the bristles for example also in the peripheral direction can be slightly bent, the tips of the bristles can be smooth, and the rate of removal of material can be appreciably varied by changing the direction of rotation of the tool. By varying the lengths of the bristles, for example, over the axial length of the tool, rods of any type of material having a profile cross-section in the longitudinal direction can be surface worked over partial contour regions.

Abstract: To ensure that a web (11) of filter material is properly passed between filter plates (25) of a filter stack (23), without skewing, which might cause leakage along the edges of the filter plates, the web is guided to the filter plates by guide rollers and, after being received from the stack of plates, passed over an inclined deflection edge (13) on a deflection element or rod, located at an angle of 45 DEG  with respect to the edge of the essentially rectangular plates, so that the run-on and run-off surfaces of the web will form a web deflection angle ( alpha ) of about 90 DEG , and a web plane diversion angle ( beta ) of 0 DEG . A plurality of deflection rod groups may be used, guiding webs alternately, for example, for example, to the right or left after having passed through a stack, or permitting passage of the webs through an additional stack (FIG. 13) since, upon passage about the deflection rods, the orientation of the surfaces of the filter web is reversed. The webs are pulled from between the filter plates after separation of the filter plates by a transport mechanism, located downstream of a last group of deflection rods. Preferably, a cleaning apparatus (41), such as a tensioned wire, is located at or adjacent the deflection element to remove filtrate and filter cake and the like from the filter web before the latter is rewound or collected for disposal.

Abstract: An electrically conductive medium flows through a tube (11) across which a magnetic field (H) is established at right angles to the flow by excitation coils (12,13).

The rate of flow is derived from the prod. of the measured velocity and the cross-sectional area (18). External stress on the tube (11) tends not to affect the minor axis (B) which remains substantially constant, so that the cross-section is unaltered in the presence of variations in pressure and temp.

Abstract: The thickening process takes place in three stages, where in the sedimentation vessel 8 a partial dewatering takes place under pressure. To increase the dewatering effect, a removal system for separated water can be installed in the sedimentation vessel 8 in the form of the collection shaft 20 with the attached hood profiles 22 which are open in a downward direction. The previously dewatered sludge is subsequently led into the aerating vessel 11 and there, similarly under pressure, aerated with gas in the form of fine bubbles. This charging with gas in fine bubble form takes place near the base of the vessel 11. The incorporation of gas into the sludge can also take place as a result of intensive mixing of the sludge/gas mixture by means of a mechanical agitator. In the final phase, the previously dewatered sludge aerated under pressure in vessel 15 is further dewatered by the action of the flotation effect. The flotation takes place under atmospheric pressure or even under reduced pressure.
