Patent number: 4913196Abstract: A cassette containing a group of sealed cells is used for delivering doses of fluid to be injected into a sterilizing chamber. After the cassette is automatically positioned over a piercing mechanism, the cassette is moved downwardly so that a cell is pierced. Fluid is then forced out of the cell by pneumatic pressure into an injector valve, which opens in a manner which does not adversely affect a vacuum within the chamber.Type: GrantFiled: May 20, 1987Date of Patent: April 3, 1990Assignee: Surgikos, Inc.Inventors: Harold R. Williams, Robert M. Spencer

Patent number: 4908163Abstract: A nonreinforced microfiber fabric is disclosed. The fabric has minimum grab tensile strength to weight ratio greater than 0.8 N per gram per square meter and a minimum Elmendorf tear strength to weight ratio greater than 0.04 N per gram per square meter. The fibers in the fabric have an average length greater than 10 centimeters and at least 80% of the fibers have a diameter of 7 microns or less. The fabric is made by thermally embossing a microfiber web which is made with a minimum of degradation to the polymer and employing high velocity secondary air to maintain air flow uniformity and fiber length.Type: GrantFiled: July 11, 1986Date of Patent: March 13, 1990Assignee: Surgikos, Inc.Inventors: Larry H.
