Abstract: In an air passage switching door, a packing material having a size approximately corresponding to a plate surface of a door base member is used, and the door base member is crossed with the packing material at a portion around a rotation shaft for rotating the door base member, so that both plate portions of the door base member are bonded to opposite surfaces of the packing material at different areas of the packing material. Accordingly, the air passage switching door can be manufactured using the single packing material.

Abstract: The present invention relates to a controller (11), a cabin pressure control system (10) and a method for controlling pressure in a cabin (30), especially an aircraft cabin. In accordance with the invention the controller (11) comprises a channel (15, 16) and a pressure differential safety function (22). The channel (15; 16) calculates a first output signal (40) for actuating an overflow valve (17) in a closed loop control based on the pressure differential between the cabin (30) and the atmosphere and additional critical parameters. The safety function (22) calculates a second output signal (41) based only on the pressure differential. The two output signals (40, 41) are compared, and the second output signal (41) is selected, if said first output signal (40) is found inaccurate. The safety function (22) assures operation of the outflow valve (17) even it the channel (15; 16) is out of function.

Abstract: A louver member is provided for forming louver assemblies for houses and other buildings for ventilation purposes.

Abstract: A venting apparatus for chemical containers comprises a vent duct having a plurality of vent ports, a flow control mechanism, and a damper. A closure of a chemical container is coupled to one of the vent ports using suitable tubing, and a second coupling connects the chemical container to equipment that uses the contents of the container. A distal end of the vent duct is coupled to an exhaust fan. In this configuration, vapors evaporating from the contents of the chemical are safely exhausted outside a work facility. As a result, a chemical container that normally would be classified as Use-Open under applicable fire codes is converted to Use-Closed, effectively enabling the work facility to substantially increase the volume of chemicals that may be contained or used in the facility under the code, without requiring upgrade of existing facilities to Hazardous Occupancy standards, or building new facilities that qualify as Hazardous Occupancy and that can use Use-Open chemical containers.

Abstract: A hidden ventilating sill plate is fundamentally a new building product, installed along the top surface of the exterior perimeter foundation. It replaces the existing wood sill plate. The invention has a continuous set of air slot channels of a proscribed size perpendicular to the longitudinal axis, along its base, communicating natural air flow from the exterior to the interior of the crawlspace. The exterior side of the slot channels can open earthwards to allow the venting to be completely hidden from view, when the sill member extends out beyond the exterior face of the foundation and wall. The vent concealment feature also functions as a base to the siding and an integral drip edge. Insect mitigation is achieve by adding a mesh screen over the exterior exposed slotted openings. The preferred material for this invention is a plastic-fiber composite, allowing rot resistance, shear capabilities and, rapid extrusion or molding of the sill profile.

Abstract: A ventilation controlling apparatus using a slide door made of a flexible film member to solve imperfect slide action attributable to film member rigidity degradation on the fringe of an aperture. The slide door is movably disposed inside a casing which forms an air passage, and the slide door is composed of the flexible film member provided with an air-circulation aperture. Ventilation of the air passage is controlled by varying an area of blending or connection between the aperture and the air passage in accordance with movement of the slide door. A rigid support member is fitted around the fringe of the aperture on the film member, thereby enhancing rigidity of the aperture fringe.
