  • METHOD OF CLEANING CONTAMINATED SURFACES
    Publication number: 20110104373
    Abstract: A method for cleaning contaminated surfaces of surgical waste management equipment. The method includes rinsing surfaces of the equipment with water to remove water soluble contaminants and waste material. A rinse solution is applied to the surfaces of the equipment to provide a residual film thereon. The rinse solution includes a first nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 12 to about 15, a second nonionic alkoxylated alcohol surfactant having an HLB value ranging from about 16 to 20, an aqueous solvent, and a bio-film permeation agent. A total of the first surfactant and the second surfactant in the composition ranges from about 2 to about 20 percent by weight of a total weight of the composition.

  • FLUID EXPANSION-DISTRIBUTION ASSEMBLY
    Publication number: 20100313585
    Abstract: An expansion-distribution assembly for simultaneously throttling, mixing, and distributing refrigerant fluid upstream of a heat-absorbing component (e.g., an evaporator) of a heat pump system. The expansion-distribution assembly comprises a valve-nozzle adjustment device which moves a pin relative to a nozzle chamber to vary flow-characteristics therethrough. The pin is moved during operation of the heat pump system (based on, for example, pressure and temperature data) to dynamically customize the valve-nozzle for the current load of the system.

  • Non-Metallic Mandrel and Element System
    Publication number: 20100294483
    Abstract: A non-metallic element system is provided as part of a downhole tool that can effectively seal or pack-off an annulus under elevated temperatures. The element system can also resist high differential pressures without sacrificing performance or suffering mechanical degradation, and is considerably faster to drill-up than a conventional element system. In one aspect, the composite material comprises an epoxy blend reinforced with glass fibers stacked layer upon layer at about 30 to about 70 degrees. In another aspect, a mandrel is formed of a non-metallic polymeric composite material. A downhole tool, such as a bridge plug, frac-plug, or packer, is also provided. The tool comprises a support ring having one or more wedges, an expansion ring, and a sealing member positioned with the expansion ring.

  • AUTOMATIC FAULT DETECTION AND LASER SHUT-DOWN METHOD FOR A LASER-GENERATED WINDSHIELD DISPLAY
    Publication number: 20100243858
    Abstract: The laser of a laser-generated windshield display is controlled to initially deflect the laser beam in the direction of a reflective target disposed outside a display region of the windshield, and a sensor disposed in a reflection path of the target is sampled to detect the presence of a feedback signal that occurs when the laser beam impinges on the sensor. If the feedback signal is detected, the laser beam is deflected onto the display region to generate a driver display; but if the feedback signal is not detected, the laser is automatically turned-off. Once the laser is turned off for lack of a feedback signal, the control is repeated following a specified delay interval so that the driver display will automatically resume the when the condition that prevented generation of the feedback signal is cured.

  • Live attenuated viral vaccines for Eastern Equine Encephalitis virus
    Patent number: 7790181
    Abstract: Live attenuated Eastern Equine Encephalitis (EEE) vaccines that outperform the PE-6 vaccine in mice aerosol challenged with >1,000×LD50. Candidates include four furin-cleavage deletion mutants and one E3 deletion mutant. Each vaccine provided protection in birds against antigenically distinct North and South American strains of EEE. The PE-6 vaccine does not provide protection against South American EEEs. Animals inoculated with each of the vaccines of the invention developed neutralizing antibodies to EEE.
