  • Publication number: 20090074589
    Abstract: In a gas turbine having a compressor discharge casing, a cooling circuit diverts compressor discharge air toward a high pressure packing (HPP) circuit. The cooling circuit includes an inlet pipe that receives compressor discharge air. One or several cooled cooling air pipes are in fluid communication with the inlet pipe via a pipe manifold, which distributes the discharge air across the cooled cooling air pipes. A seal is disposed upstream of an entrance to the HPP circuit to limit flow into the HPP circuit, and a second seal is disposed downstream of the HPP circuit at turbine wheelspace to limit ingestion and thus the purge flow air required. The circuit serves to reduce required purge flow in the HPP circuit so that an amount of compressor discharge air can be put back to the main flow path, thereby improving turbine performance.

  • Publication number: 20070157630
    Abstract: Conditioned air discharged from a vehicle heating, ventilation and air conditioning (HVAC) unit is further conditioned by a thermoelectric (TE) air conditioning unit and then directed to air passages in a vehicle seat. Activation of the TE air conditioning unit is based on climate control parameters utilized by the HVAC unit, including a set temperature, radiant heating effects, and cabin air temperature. The climate control parameters are utilized to establish a target seat temperature that optimizes occupant comfort and the transient response of the seat cooling effect.

  • Publication number: 20060283131
    Abstract: A hurricane shutter escape mechanism for allowing fast and easy removal of conventional hurricane shutters from a window or door of a structure in the event of an emergency. The device comprises a release member, an anchor, a removable stud for engaging and securing the hurricane shutters, and a spring-actuated panel fastener that includes a leaf spring to engage and hold the removable stud in position. The release member includes a slot having a small aperture to hold the stud in position and a large aperture to release the stud from the anchor. From inside the building, the release member is pushed down to release the hurricane shutters so that the occupants of a structure can escape during an emergency, such as a fire. From outside the building, a rescuer can depress the leaf spring to remove the spring-actuated panel fastener, and thereby, also remove the hurricane shutter panel.

  • Publication number: 20050270234
    Abstract: The present invention relates to a system and method for locating the direction and distance to a RF signal source from an avalanche beacon to find an avalanche victim. The system and method includes a RF signal locator and a graphical display residing on the signal locator. The receiver graphical display provides the searcher with an initial way point reading that includes directional and distance data associated with the beacon RF signal source from the avalanche beacon. The directional and distance data is based upon the received RF signals. A processor within the locator receiver receives and measures RF signals emitted by the RF signal source. The locator advantageously provides continuous subsequent way point readings for the user, where the subsequent way point readings include directional and distance data associated with the RF signal source. The distance data provided by the subsequent way point readings is based upon a path loss slope of the received RF signals from the avalanche beacon.

  • Publication number: 20050103031
    Abstract: In order to reduce refrigerant leakage from an automotive air conditioning system, the leakage paths are kept sealed by automatically reducing the output of a variable displacement compressor (12) after initial operation of the engine for a predetermined number of five minutes, and then only for a predetermined number of ten seconds, that is, so long as there has been an air conditioning on signal by the operator. After the reduction in output for ten seconds, the output of the compressor (12) is returned to full output for a predetermined number of two air-conditioning minutes, which is then followed by another ten seconds of reduced output.
