A hydrological barrier plate for in-grade light fixture housings and a housing for use with light fixtures to prevent water entry into the water sensitive compartments of the light fixture. The barrier plate has a plate body with an opening in which is sealably disposed an anti-syphon wire pass-through valve for electrically connecting the components on one side of the barrier plate with the wires in the junction box on the opposite side of the barrier plate. The barrier plate is sealed around its outer edge against the housing wall. The pass-through valve is configured to prevent water from wicking along the wires and to prevent water from passing around the valve. The barrier plate is installed without tools and an effective seal is easily obtained. Using the barrier plate, water is prevented from migrating between the junction box and the primary housing compartments of the housing.       Recently Added Patents System for billing rating and selection of accounts Battery Thin film transistor having a crystalline semiconductor film including indium oxide which contains a hydrogen element and method for manufacturing same Method and apparatus for providng and using public transportation information Periodic magnetic field generation device, and linear motor and rotary motor using the same Heat exchanger for vehicular air conditioning apparatus Bacillus thuringiensis gene with lepidopteran activity   Randomly Featured Patents Optical attenuator CLI configuration dump command support generation Plant wrapper Power savings in a voltage supply controlled according to a work capability operating mode of an integrated circuit Method for encrypting data using IEEE 1394 serial bus network Ring voltage termination by means of a spare fuse Methods of forming field effect transistors, methods of forming field effect transistor gates, methods of forming integrated circuitry comprising a transistor gate array and circuitry peripher Digital programmable delay scheme to continuously calibrate and track delay over process, voltage and temperature Ice distribution system and method Electrical connector housing © 2006-2008 PatentGenius.
