Abstract: Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

Abstract: A compressor assembly includes compressor means having an inlet, an outlet and a means for drawing air through the inlet and exhausting compressed air through the outlet, rotary drive input means, and gear means for changing the speed of the rotary drive input means and having an input connected to the rotary drive input means and an output driving the compressor means, the gear means comprising planetary gear means.

Abstract: To permit accurate centering by means of compression rings which are pressed against conical surfaces of a tubular element inserted in the hub, and a sleeve with conical surfaces placed on the shaft, the compression rings are formed with axial centering ring extensions which, at their inner and outer surfaces engaging the hub, and the shaft, respectively, are bowed or curved in cross-section to be, for example, at least approximately part-spherical. Sequential tightening of bolts to draw the compression rings together and the respective conical surfaces over each other thus will not result in misalignment of the compression rings, or tilted or slanted bindings thereof with respect to the hub, or shaft, respectively, but insure accurate positioning of the compression rings, with the centering extensions around the shaft and within the hub.

Abstract: The wires or strips (corona-discharge electrode elements) of a corona-discharge electrode are tensioned in the support frame thereof by anchoring one end of each element to a bar of the frame, drawing the other element with a predetermined tension by fluid pressure toward an opposite bar of the frame, and anchoring the latter end to this bar. The tool for tensioning the element comprises a caliper or C-shaped member, one arm of which is provided with a fluid cylinder whose piston bears against the latter bar, and means on at least one arm of the caliber engaging the electrode wire or strip. Preferably the arm opposite that on which the cylinder is provided has means for engaging or guiding the electrode element.

Abstract: To decrease the cost of such a connection, and increase power transmission as well as decrease stresses on the shaft, conical surfaces formed of respective inner and outer clamping rings are so arranged that one of the conical surfaces has an engagement friction relationship which provides for self-binding, whereas the other conical surface does not have self-binding engagement friction; the difference in engagement friction can be obtained by changing the cone angles, or the surface characteristics of the engaging surfaces.

Abstract: To couple a hub having a connecting boss to a shaft, with improved centricity and torque transmission, the hub is formed with a ring groove in the end face leaving a protruding boss surrounding the shaft, in which ring groove a pair of concentric rings having matching continuous conical surfaces are inserted, the depth of the ring groove, and the rings themselves being so relatively dimensioned that, in loosely assembled condition, the inner surface of the outer ring is spaced from the axially facing surface of the ring groove by a pretermined distance which is taken up during tightening, the inner face of the ring groove then forming a stop or abutment surface upon such axial tightening of the outer ring over the inner ring to completely fill the ring groove and provide for radial support of the hub in the region of the ring groove as well as for transfer of power from the shaft to the hub by engagement of the boss of the hub with the shaft, and of the rings with each other and with the hub, respectively.

Abstract: To simplify manufacture of double conical hub-to-shaft connections and to improve centricity, a double conical centering ring is located intermediate the connection, formed with a cylindrical groove, so dimensioned that it will entirely receive a radially resilient ring, which ring can snap into a matching ring groove formed on a double conical surface, to entirely fill the groove and accept compressive forces without deformation of the conical surfaces adjacent the groove.
