Abstract: ABSTRACT OF THE DISCLOSURE           An integral clarifier is provided that operates without a pump by deriving the clarifier feed stream and its accompanying pump head from the flow being pumped through the draft tube of a draft tube circulator/aerator assembly in a complete mix system or in a basin oxidation ditch.  The clarifier feed stream is delivered to the clarifier with this pump head substantially intact to create a differential hydraulic head between the surface of the clarified liquor within the clarifier and the surface of the mixed liquor within the complete mix tank or within the endless channel of the barrier oxidation ditch.  The clarifier may be located in any suitable place but is preferably alongside the complete mix tank or alongside the discharge channel of the barrier oxidation ditch, within the discharge channel so that its upstream side forms the barrier, or surrounded by the endless channel, particularly if the clarifier and the ditch are circular in shape.

Abstract: ABSTRACT OF THE DISCLOSURE           A device for determining hydrogen flux through a metal membrane comprises two parts, a top part and a bottom part respectively.  The top part is electrically insulated relative to the bottom part.  The top part which is a sheet of iron or steel, is provided with an interior palladium coating.  The top part constitutes together with the interior coating a metal membrane which is selectively permeable to hydrogen.  Within the bottom part which is made of a metal, e.g. nickel, or nickel-coated steel, a metal oxide filling is arranged.  The bottom part constitutes together with the metal oxide filling a metal/metal oxide cathode.  The device is also provided with an electrolyte solution electrolytically communicating with the metal membrane and the metal/metal oxide cathode.  The device is adapted to be maintained in a substantially short-circuited condition by either a direct connection between the metal membrane and the metal/metal oxide cathode or a connection to a current measuring system with low internal impedance, such as a conventional am-meter.

Abstract: ABSTRACT OF THE DISCLOSURE     A thurst bearing device for high axial loads, particularly for journalling blades in an axial flow fan impeller.  A thrust bearing device for high axial loads comprises two thrust bearings which are series-coupled with respect to the loading forces, and in which the two outer race rings are relatively movable, whereas the two inter-mediate race rings are rigidly connected and are prevented by means of two springs surrounding the race rings in each bearing to exert a lateral clamping action thereon from turning in one and the other direction of revolution, respectively, relative to each respective one of the outer race rings.  An intermediate ring rigidly connected with the intermediate race rings comprises a cylindrical wall with a central portion opposite the race rings and outer portions with a reduced wall thickness on either side of the central portion opposite the ball holders of the two bearings. Holder parts surrounding the outer race rings have wall portions surrounding the sides of these race rings.  In order to reduce the hysteresis of the bearing device and avoid a risk of blocking of the bearings due to clamping of the windings of the helical springs, the springs for each bearing surrounds an outer portion of the intermediate ring and the wall portion of the holder part around the outer race ring of the respective bearing and are surrounded on their external side by external rings.

Abstract: ABSTRACT       An elastomechanical sphincter comprising a prosthetic device for implantation about a patient's lumen such as the urethra for occluding or relaxing the lumen for the treatment of incontinence. The prosthetic sphincter includes a body of elastomeric polymer material configured to define an articulating structure (10, 52) having a normally closed elongated occlusion orifice (11, 53) arranged to embrace the patient's urethra with minimal ischemic interruption of circulatory blood flow. In a first sphincter embodiment, an integrally formed manually manipulable pressure relief cuff (14, 15) extends from a peripheral portion of the articulating structure (10) in such a manner that physical pulling on the pressure relief cuff in a direction transverse to the elongation of the occlusion orifice will open the orifice and thereby open the lumen. The natural elasticity of the device results in occlusion of the lumen upon releasing of the pressure relief cuff. In a second sphincter embodiment, the articulating structure (52) includes a hollow chamber (54) formed therein which is adapted to receive a fluid under pressure from an associated fluid reservoir (64).     As the chamber is filled, the articulating structure expands at a portion (52-1) thereof in which the hollow chamber is located, such that the occlusion orifice thereof applies a corresponding increased pressure to occlude the patient's lumen.  A pressure relief disk (91) or surface (112) is provided which may be manually operated while  in  situ  to  permit  fluid  to  be transferred from the chamber to thereby reduce the occlusive pressures being applied by the occlusion orifice, whereby to permit an opening of the patient's lumen thus maximizing the movement of material (e.g. blood) therethrough.
