US Patent:

44154178, Nov 15, 1983

Filed:

Jul 19, 1982

Appl. No.:

6/399578

Inventors:

Lee W. Bush - Chesterfield MO
Marie S. Chan - Pittsburgh PA
Gary P. Craun - Bridgeville PA
William J. Erlanson - Pittsburgh PA
Wood E. Hunter - Pittsburgh PA
Wallace B. Ramsey - Pittsburgh PA

Assignee:

Calgon Corporation - Pittsburgh PA

International Classification:

C08F 250

US Classification:

20415924

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.

Assignee:

Calgon Corporation - Pittsburgh PA

International Classification:

B65D 3700

US Classification:

222207

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.

Assignee:

Calgon Corporation - Pittsburgh PA

International Classification:

B65D 3528
B67D 506

US Classification:

222 52

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.
