Abstract: The head for the hydrostatic detection of a liquid level includes a main enclosure which is divided by a membrane into two chambers, one of which communicates with a supply of air under pressure, while the other is joined to a probe that is immersed deeply into the liquid. That connection is made, in this case, by the intermediary of an auxiliary enclosure that also contains a primary chamber that communicates with the inlet of the air under pressure, and a secondary chamber which is separated from the primary chamber by a membrane. That membrane forms one piece with a valve mounted between the chamber and a small connecting conduit connected with a probe, which prevents any ill-timed rise of the liquid inside the device, in the case of the disappearance of the compressed-air supply, and which makes it possible, at the same time, to install the detector head above the tank.

Abstract: The invention relates to a method and apparatus for sorting out recycled paper pulp obtained from scrap material containing contaminants in the form of large pieces of foreign material such as plastics, adhesives, pieces of rope and the like. The invention avoids the need to disintegrate such large pieces of foreign material prior to their removal. The device of the invention comprises a drum (1) with an horizontal axis (2), an end wall (3) of the drum being fitted with a perforated plate (4) and an helical stirrer (5) having profiled blades rotating in a plane parallel to this plate at a short distance thereof, these blades having a transverse cross-section with a hydrodynamic profile adapted for generating a depression in front of the perforated plate, and a leading edge (6) forming a Bernouilli spiral with a constant angle of approximately 30 DEG , the drum (1) comprising a pulp inlet (10) with a valve (11) located opposite the perforated plate, an auxiliary enclosure (7) for recovering accepted pulp behind the perforated plate, connected to the suction side of a pump (8), a water inlet (12) with a valve (13), a vent (16) and a large bottom opening (14) with a valve (15) for discharging the refuse after the accepted pulp has been recovered. While the above-described device is designed for batch operation, a modified embodiment is provided in which twin units of the above design are associated for continuous operation (1a and 1b, FIG. 5) controlled by a 3-way valve (24) for alternatively feeding contaminated pulp to either sorting unit. In either case, the refuse is washed clear and water is drained out of the refuse before its discharge, so that it may be readily discarded without further processing, and the stirrer permanently prevents the perforated plate from becoming plugged.
