Abstract: Disclosed is an improved chain return support suitable for use in an en masse grain conveyor. The chain return support is comprised of track comprised of a pair of angle irons extending lengthwise in the interior of a trough and supported by horizontal cross members bridging two side walls of the trough. The angle irons have inwardly facing horizontal edge portions and vertical lower portions. A plastic slide is inserted between the angle irons and is engaged with the angular edge portions by way of grooves extending lengthwise on side surfaces of the plastic slide. Stops on the cross member contact the lower portions of the angle iron for proper positioning of the track. The plastic slide provides a low friction surface for supporting the chain return section.

Abstract: A valve (10) for controlling flow of hydraulic fluid.          The valve (10) includes first and second valve members (80, 82), each having a plurality of lands and grooves.  The valve members (80, 82) are relatively movable from a neutral position to a displaced position in which surface segments (202, 226, 208, 218) of respective pairs of lands overlap to form flow gaps (232, 234) for restricting flow of fluid between respective pairs of grooves.  At least one (234) of the flow gaps is divergent by having a cross-sectional flow area which increases along a direction of fluid flow therethrough and at least one (232) of the flow gaps is convergent by having a cross-sectional flow area which decreases along a direction of fluid flow therethrough.  The flow gaps (232, 234) have minimum cross-sectional flow areas (A, B) defined by the surface segments.  The flow gaps (232, 234) are sized such that the minimum cross-sectional area (A) of the convergent flow gap (232) is larger than the minimum cross-sectional area (B) of the divergent flow gap (234) at a first rotational position, and are sized such that the minimum cross-sectional area (A) of the convergent flow gap (232) is smaller than the minimum cross-sectional area (B) of the divergent flow gap (234) at a second rotational position for suppressing valve noise.

Abstract: The measurement of blood flow in a dialysis shunt (12) is obtained by injection of an indicator material into a venous line (32) leading from dialysis equipment (10) to the shunt (12). The blood flow in an arterial line (26) leading from the shunt (12) at a location downstream of the venous line (32) to the dialysis equipment (10) is monitored by an arterial line sensor (50) for the presence of the indicator material. A detector (58) connected to the sensor (50) provides a dilution curve in response to the presence of the indicator material and the blood flow in the shunt (12) is calculated from the area under the dilution curve. The locations of the arterial and venous lines (26, 32) in the shunt (12) can be reversed to obtain a measurement of blood recirculation from the venous line (32) into the arterial line (26).

Abstract: A syringe for dosed injection of a medicine from an exchangeable cartridge h as a housing comprising a cartridge holder and a dosing mechanism by which a dose is set and subsequently injected by successively advancing a piston rod to press a piston into the cartridge. The dosing mechanism comprises a threaded spindle and a nut member co- operating with the spindle. A dose is set by relative rotation of the spindle and nut member whereby the nut member is moved along the spindle . The position of the nut member on the spindle defines how far the piston rod is advanced. The spindle and the nut is locked agains t relative rotation when the dosing mechanism is not operated to set a dose. Access to the cartridge holder is obtained by opening a lid connected to the housing and coupled to the dosing mechanism in such a way that the locking of the nut element in its position on the spindl e is released when the lid is opened, and the opening movement of the lid is transmitted to a piston rod retraction mechanism.

Abstract: The alternator on an engine has a set of stator coils which are connected to supply current to power accessories and current for a battery charger when the engine is running. When the ignition is turned off, a braking switch is closed which short circuits the stator coils. The resulting high current in the stator coils produces a braking torque on the engine shaft that brings it and any attached implement to a rapid halt.
