    Abstract: The invention is concerned with a novel container for receiving a liquid material having a fitting at one end adapted to provide a discharge port for the liquid within the container and having at its other end a plunger or piston adapted to be moved within the inside wall of the container to discharge one or more predetermined "aliquots" or "doses" of liquid from the container through the port. The invention also comprises a novel device adapted to receive a liquid-containing cartridge or package of the type just mentioned and having means for coacting with the package to move the plunger within the container during dose-dispensing or -discharge in such a manner as to gradually accelerate movement of the plunger from a position of rest within the container through a maximum rate of motion and then gradually decelerate the motion of the plunger to a final position at the end of the dose-discharge. The device also comprises means for accurately predetermining or "measuring" the amount of liquid discharged during each individual movement of the plunger. The device may comprise means for repeatedly actuating the piston with an accelerating-decelerating movement to discharge a plurality of measured samples repeatedly under non-spurt and non-splash conditions.

    Abstract: An automatically controlled test tube transporter apparatus which advances a test tube rack containing two rows of receptacles for test tubes under a vertically movable aspirating and dispensing tip or nozzle which is adapted to move down into adjacent tubes and aspirate or discharge depending on the test to be performed. The tip is operationally in communication with a twin pipette metering and dispensing apparatus which includes a linearly adjustable eccentric mechanism which drives the pipette pistons with a motion of adjustable sinusoidal amplitude. The apparatus includes a solid state control circuit which includes a binary shift register. The pipettes may be adjusted to either work in parallel or alternating strokes. An automatic tip wiping mechanism, controlled by the operation of the tip, is provided to insure precision in the processing. The apparatus is adapted to be set for continuous operation or for individual test tube processing cycle operation. Empty racks can be advanced without engaging the tip and pump apparatus. The pipetting mechanism may be operated separately without the operation of the transporting mechanism. A malfunction and alarm logic circuit gives a warning in case of certain malfunctions and stops the apparatus.
