Publication number: 20130279987Abstract: Slurry walls and methods of using those slurry walls to seal unlined solar ponds are provided. The slurry walls are formed from a mixture comprising clay and cement in water. A trench is keyed into the dike surrounding the solar pond, down to a geotechnically predetermined level. The slurry is deposited into the trench and allowed to harden, after which it is covered with a membrane or other covering. The inventive slurry walls reduce, and preferably prevent, leakage of water from the solar pond.Type: ApplicationFiled: June 20, 2013Publication date: October 24, 2013Inventors: Mark Reynolds, Thomas S. Burton, Corey R. Milne, Steven R. Day

Patent number: 7264606Abstract: A method for providing at least partial bypass of the heart to supplement the pumping function of the heart to thereby enable the surgeon to perform various surgical procedures thereon includes providing a circulatory assist system having a portable extracorporeal axial flow pump with a pump housing, a rotating pumping member disposed in the pump housing and inlet and outlet cannulated tubes respectively connected to inlet and outlet ports of the pump housing, accessing the patient's left atrium of the heart with the inlet cannulated tube, accessing the aorta with the outlet cannulated tube, actuating the rotating pumping member to draw oxygenated blood from the left atrium of the heart through the lumen of the inlet cannulated tube and into the inlet port of the pump housing whereby the pumping member imparts mechanical energy to the oxygenated blood passing through the pump housing and directs the oxygenated blood through the outlet port and through the lumen of the outlet cannulated tube to be transferredType: GrantFiled: April 5, 2004Date of Patent: September 4, 2007Assignee: United States Surgical CorporationInventors: Robert Jarvik, Daniel E. Alesi, John F. Klinger, Robert J. Geiste, Steven R. Day, Keith Payea, Kenneth G. Hammerquist, Steven J. Stern, Francis X. Kaczynski, Mark Howansky, Deborah M. Cashin

Patent number: 4730921Abstract: An automated vertical photo densitometer for reading solutions contained in microwell plates. The densitometer utilizes an optical system for minimizing the optical effect of a meniscus on the fluid sample. The invention also discloses a method for determining a centrally located position of a microwell beneath an interrogating beam of light by controlling the size of the light beam and by stepping the well through the beam. A measurement of the light intensity received by a detector is taken at each step. A maximum light intensity value is selected as corresponding to a well position wherein a central area of the fluid sample is substantially within the interrogating beam.Type: GrantFiled: October 31, 1985Date of Patent: March 15, 1988Assignee: Genetic Systems, Inc.Inventors: Gerald L. Klein, Gene D. Russell, Steven R. Day, Jerrold D. Liebermann
