Patent number: 7637766Abstract: A receptacle assembly for a twist-lock photocontrol that is mounted on a luminaire housing. The assembly includes a receptacle and a spring clamp. The receptacle has a disc portion with a hub extending from the central portion of the back side, a perimeter side wall with a castellated bottom edge that engages stops on the luminaire housing. Three fingers extend from the back side of the disc and terminate at a lip edge. The spring clamp has a substantially flat, ring-shaped body that includes a top surface, an opening, an inner edge, an outer edge, and at least one pair of spring members. The receptacle is attached to a luminaire housing using the spring clamp. The orientation of the receptacle can be adjusted and can be locked into a stationary position without tools.Type: GrantFiled: September 19, 2008Date of Patent: December 29, 2009Assignee: Howard Industries, Inc.Inventors: Rick Kauffman, Jason Cook, Gerald Ballard, William E.

Patent number: 5405766Abstract: Enzymes and certain other bioactive substances are immobilized on solid substrates which have sufficient functional groups such as hydroxyl or carboxyl. The bioactive substances are linked to the substrates through spacer compounds having a long open alkyl chain with 7-18 carbon atoms and also through phospholipid intermediates. The spacer compound is chemically linked to the substrate. The phospholipid is covalently linked to the spacer compound. Immobilized bioactive substances of the invention exhibit a marked increase in activity and stability. In a preferred embodiment, immobilized enzymes having a high degree of resistance to thermal inactivation are prepared.Type: GrantFiled: March 25, 1993Date of Patent: April 11, 1995Assignee: Her Majesty the Queen in right of Canada, as represented by the Minister of National DefenceInventors: Krishna M.

Patent number: 5133625Abstract: A system and method for establishing, maintaining or enhancing microorganisms utilized to remediate contaminated soil or groundwater which includes of a direct push rod or cylinder equipped with a fluid or gas delivery system. The system also includes computer-based monitoring capabilities which can monitor or control the subsurface events. Microorganisms, nutrient solutions, or gases such as air can be introduced into the subsurface environment of predetermined locations. The delivery device is a long rod or cylinder which is pushed into the ground via applied pressure at the surface. The internals of this device contain tubing or other means to deliver fluid through openings in the rod or cylinder to the surrounding environment. The fluid may be driven into the environment by surface pumps or gas pressure. The delivery rod or cylinder may be withdrawn for reutilization or left in place for continuous service.Type: GrantFiled: February 22, 1990Date of Patent: July 28, 1992Inventors: Nicholas Albergo, Philip B. Hildebrand, William E. Lee, III

Patent number: 4645679Abstract: A process for making a corn chip with potato chip texture is described. The chip has increased mouthmelt, crispness, and lightness like potato chips and it is less hard and gritty than standard corn chips. It also has a distinctive corn flavor. In a preferred process, corn is cooked in water at 140.degree. F. (60.degree. C.) to 212.degree. F. (100.degree. C.) for 30 minutes to 4 hours. The corn hulls are removed, and the corn is comminuted. A starch material is cooked in water until it is adequately hydrated, and then comminuted. The comminuted corn and starch material are mixed together to form a dough having a ratio of corn to starch material of 95:5 to 80:20. The dough is extruded, formed into a sheet, cut into segments, and deep-fried to form the finished chip.Type: GrantFiled: December 24, 1984Date of Patent: February 24, 1987Assignee: The Procter & Gamble Co.Inventors: William E. Lee, III, James M. Bangel, Robert L. White, David J. Bruno, Jr.
