Abstract: Abstract Anticoagulant is added to blood being aspirated through a hand-held wand having a venturi throat.  The anti-coagulant flows into the wand from a generally closed anticoagulant  reservoir  higher  than  the  wand  as replacement  air  flows  into  the  anticoagulant  air reservoir.   This  air  inflow  is  controlled  by  a regulator fixed on the wand and in accordance with the amount  of aspirated  blood  flowing  in  through the venturi throat.

Abstract: Abstract of Disclosure The invention concerns a filtering unit comprising a filter dia-phragm     , a backing surface      disposed against the diaphragm, and passages through which the liquid to be filtered can be sup-plied on one side of the diaphragm and the liquid that has drained through the diaphragm can be removed from the opposite side of the diaphragm. As taught by the invention, the backing surface      is provided with ridges      lying side by side and with grooves, moving liquid in the direction parallel to the diaphragm , between them and which start in the central part of the surface in different directions and lead to the periphery of the surface, curving in such manner that the spacing of mutually adjacent ridges is substantially constant on the entire area of the backing sur-face. The backing surface      will then to the filter diaphragm lend throughout uniform support. When the filtering unit has a backing surface      of said kind on both sides of the filter diaphragm  , the unit may be shaped to be a closed entity in which the filter diaphragm is cleanable after each filtering run by the aid of washing liquid conducted in the direction opposite to the filtering. Such a filtering unit, by which continuously repeat-ed filtrations can be carried out, is particularly appropriate for use as a component in automatically operating equipment.

Abstract: Abstract of the Disclosure:        Disclosed is a sliding gate valve and clamp mechanism which permits the utilization of bandless refractory for the top plate, sliding gate, and the attachment of a replaceable collector to the sliding gate. The refractory is formed with curvilinear side edges tapered centrally toward the inter face portion between the top plate and sliding gate plate.          Curvilinear edges are employed on both the stationary plate and the sliding gate, and desirably both have an identical exterior configuration, but optionally differ in the central portion where the well block nozzle is engaged by the stationary plate and where the collector is engaged by the sliding gate plate. Optionally a secondary sealing ring is employed to form a seal between the lower well nozzle and the top plate in a zero clearance environment.  Also desirably the top plate and sliding gate plate may both be ground on both faces to provide parallelism and planarity of the refractory faces. In certain embodiments the stationary plate and slide gate are identical.

Abstract: ABSTRACT OF THE DISCLOSURE:           In a waveguide structure, there is provided a waveguide section rotatable about its longitudinal axis and an electric DC stepper motor arrangement. The rotor of such an arrangement is constituted by magnetic returns fixedly mounted on the waveguide section, and has a rotation axis which coincides with the longitudinal axis of the section. The rotor is therefore rotatable with the waveguide section about the longitudinal axis of the same. The motor arrangement further includes a stator provided with a plu-rality of poles which cooperate with the magnetic returns to rotate the waveguide section so as to adjust as desired its angular position. When the waveguide section has a circular cross section and is provided with two diametrically opposed lines of tuning screws, the waveguide structure forms a microwave polarizer which can be used in a variable power combiner.
