  • Peristaltic fluid dispenser
    Patent number: 4778085
    Abstract: A peristaltic apparatus for dispensing a fluid, which contains a mounting plate, a container support/anvil connected to the mounting plate, a rigid container for holding the fluid to be dispensed, a flexible dispensing tube which is connected to the bottom of the container and which contains a check valve, a housing which encloses the container support and dispensing tube and an actuator which integrally contains a flexible spring bar which exerts a peristaltic force on the flexible tube, thereby forcing fluid from the dispenser.
    Type: Grant

    Assignee: Calgon Corporation
    Inventors: Lee W. Bush, George A. Rauh
  • Photo-electric controlled dispenser
    Patent number: 4645094
    Abstract: A fluid dispenser for dispensing liquid detergents, soaps and germicides. A pressure plate imparts a squeezing force to a flexible reservoir containing the liquid material to force the material therefrom. A battery operated photoelectric device is positioned adjacent the dispensing valve which is opened for a timed period upon locating an object such as a hand, near the photoelectric device. Also, a device is provided to control the power to the photoelectric device upon sensing the condition of the ambient room lighting.

  • Photopolymerization using copper ions
    Patent number: 4415417
    Abstract: Photopolymerization of monomers by visible light using a photoreducible dye, a reducing agent and a controlled level of copper ions allows for high molecular weight polymer formation. The molecular weight is found to be proportional to the copper ion concentration. At 10 to 1,000 ppb copper ion concentration, the molecular weight of the polymer is optimum.
