    Abstract: A dispensing apparatus provides a fluid flow path of the recirculating type. A pump provides circulation of fluid within the flow path from a reservoir through a dispenser whose nozzle output may be disposed for dispensing. An actuator is coupled to the dispenser and operates to dispense from the nozzle an accurate measured volume of fluid at times when the pump is inoperative and the fluid within the flow line is otherwise static. Fluid is dispensed upon distortion of the flow line as a result of displacement of surrounding fluid in a closed system.

    Abstract: A self-valving fluid reservoir and bubble trap for a fluid flow line is disclosed which comprises a tubular conduit carrying a transverse, flow-blocking partition in the conduit flow path. The conduit defines upstream and downstream lateral ports on each side of the partition to permit fluid communication between the interior and exterior of the conduit. A flexible, expansible and collapsible, sealed reservoir chamber is mounted on the conduit to enclose the lateral ports. The chamber receives excess fluid in the flow line by expansion, but collapses against and occludes the downstream port or ports in the absence of excess fluid in the reservoir chamber.

    Abstract: An injection site for a flow conduit for biological fluids and the like, such as blood or parenteral solutions, is provided having improved resistance to leakage through needle punctures, even when the pressure within the flow conduit is substantially different from the pressure outside of the conduit. The conduit comprises tubing made of a biologically compatible material, in which a portion of the tubing is surrounded by an elastomeric sleeve injection site. A second elastic sleeve surrounds the first elastomeric sleeve, the second sleeve having an unstretched inner diameter which is less than the outer diameter of the elastomeric sleeve. As a result, the elastomeric sleeve is compressed by the second sleeve, whereby the sealing of the elastomeric sleeve after puncture by a needle is improved.

    Abstract: A multi-wavelength photometer using a two-segment rotating circular variable filter to select the working wavelengths. Selection is made by gating respective integrating circuits receiving signals generated by a light beam passing through the filter and the sample cuvette. The gating signals are produced by variable delay circuits triggered respectively by timing pulses derived from an apertured timing disc mounted on the same shaft as the rotating filter. The timing pulses are generated by spaced photo diodes located adjacent the timing disc and receiving light through the aperture of the timing disc as it passes.

    Abstract: An apparatus to measure the difference in intensity between periodically recurring reference and measure light pulses of different wavelength reaching a photomultiplier tube, the apparatus having alternately keyed steady voltage-generating circuits keyed in synchronism with the light pulses and generating concurrent steady d.c. electrical signals with amplitudes corresponding to the light pulse intensities which are furnished to the respective inputs of a differential amplifier. The output of the differential amplifier is therefore a steady signal representing the difference in intensity between the reference and measure light pulses.

    Abstract: An apparatus for operating a liquid dispensing syringe in successive discrete equal forward strokes to thereby dispense corresponding equal successive amounts of liquid. The apparatus consists of a support in which the syringe is clamped in alignment with an actuating rod. The end of the rod is connected to the syringe plunger. The rod is connected through a unidirectional ball and cone coupling assembly and a coupling bar to the piston rod of an air-operated cylinder assembly arranged parallel to the actuating rod. The coupling bar extends through a yoke on which is mounted a micrometer for accurately establishing the reset position of the coupling bar, and thereby setting the length of the dispensing stroke of the syringe plunger.
