  • Publication number: 20070297941
    Abstract: This present invention provides materials for use as solid or concentrated chemical precursors for the production of organic peroxy acids (peracids). Organic peroxy acids are formed using a precursor according to the invention when they are combined with hydrogen peroxide or a hydrogen peroxide precursor such as a percarbonate or a perborate in aqueous medium. Organic peroxy acids, such as peroxyacetic acid, are used currently to disinfect medical equipment such as endoscopes and related items.

  • Publication number: 20070212256
    Abstract: Provided herein are systems and methods associated therewith for killing molds and reducing other contaminating bioburden that may include bacteria and their spores, yeast, and viruses within various dwellings including homes, office buildings, institutions, and any other enclosed space in which humans reside, either temporarily or permanently. The technology of the present invention can be used to treat vehicles, airplanes, and ships. A process according to the invention includes the generation of a gaseous oxyhalogen species and distribution of the gaseous oxyhalogen species throughout a selected dwelling. It has been unexpectedly found that the concentration level of gaseous oxyhalogen species necessary to kill molds according to the inventive methods is far below that previously recognized in the art as being necessary for the killing of such molds. Thus, mold infestations may be killed in dwellings with minimal disruption to the usual business of the inhabitants.

  • Publication number: 20050150665
    Abstract: A fire extinguisher includes a tank and a gas generator breech connected to the tank. The gas generator breech is provided with a hermetically sealed gas generator cartridge. The hermetically sealed gas generator cartridge avoids the need to have a release poppet or burst shims on the gas generator breech. The enclosed space that contains combustion gas pressure is provided by the gas generator cartridge itself and not the gas generator breech. The gas generator cartridge is made from a container that can be the precursor to a beverage can used for carbonated beverages. The beverage can may come in a thickness and material of construction that makes it a suitable, cost-effective container for the gas generator cartridge. However, other containers besides precursors of beverage cans can be used.

  • Patent number: 6025841
    Abstract: A method for managing simultaneous display of multiple windows in a graphical user interface (GUI). A computer system with a display and user interface input device displays a primary or container window on the display, comprising a predetermined region for displaying information and/or receiving user commands associated with a first computer process. The system displays a target window comprising a predetermined region for displaying information and/or receiving user commands associated with a different computer process. The target window is typically displayed in a higher z-order relative to the primary window to maintain it on top. In response to a predetermined triggering condition, the target window is manipulated by movement, temporary disappearance, and/or size reduction, while maintaining the relative z-order of the target window relative to the primary window and away from a predetermined avoidance region associated with the first computer process.

  • Patent number: 4839587
    Abstract: A test fixture for TAB (Tap Automated Bonding) circuits includes circuit boards for maintaining a characteristic impedance to inner lead bond areas of a circuit under test. A plurality of vertically disposed test pins are soldered to conductors in one of the circuit boards, and provide contacts for supplying power and test signals to test pads on a circuit under test. A thermoelectric heat pump is thermally connected to a circuit under test with a copper thermal chuck or heat spreader, and is used to subject the circuit to a wide range of operating temperatures. A two piece anvil is provided to apply pressure to the test pad/test pin interface and to the circuit die/thermal chuck interface.
