  • Apparatus and method for verifying the volume of liquid dispensed by a liquid-dispensing mechanism
    Patent number: 8434345
    Abstract: An apparatus for improving the procedure for quantifying the volume of liquid dispensed by a liquid-dispensing mechanism of an analytical instrument. The apparatus of this invention comprises (a) at least one weigh cup; (b) at least one standard mass; (c) at least one transducer assembly to convert a value of weight to an electrical response; and (d) at least one electronic circuit for converting the electrical response to a measurement of volume. This invention provides a method for calibrating readings of the volume of liquid dispensed by a liquid-dispensing mechanism of an analytical instruments so that absolute measurements of the volume of liquid dispensed can be obtained.
    Type: Grant

  • Control system for valveless metering pump
    Patent number: 5120199
    Abstract: A control system for the working piston of a valveless metering pump for the precision delivery of fluids to a plurality of sequentially spaced output ports is adapted to control and alter the speed of rotation of the pump piston depending on predetermined angles of rotation of the piston as it cycles.
