Abstract: A fibreboard, insulating, wall panel includes an integral air and vapor barrier of metal foil or metallized plastic film adhered to one surface of the panel. Panels are attached to a stud wall frame. Abutting panel joints are taped to provide a continuance vapor barrier. Increased thermal and acoustic insulation as well as structural integrity of the barrier is provided by the panel.

Abstract: This invention relates to a valve assembly that has a seat for the flow control seal that is contained on a sleeve-like seating assembly that sits upon a shoulder in the housing whereby the extension of the seating assembly beyond the lower end of the housing in a downward and axial direction is fixed. This construction insures that the seat for the flow control valve must be withdrawn from the faucet body with the rest of the valve assembly.

Abstract: In a liquid loading system for the gravity loading of a liquid storage tank from a tank truck the present invention provides an improved mechanism for interrupting the flow of liquid when the level of liquid in a tank rises above a predetermined level. The structure includes a valve in the fill line which is moveable between an open position and closed position. A pressure responsive latch means is provided for releasably locking the valve in the open position. A vent passage communicates between the pressure responsive latch means and a predetermined level below the upper end of the underground storage tank. A vacuum passage communicates between the vent passage and a vacuum source in the fill line. The flow of liquid through the liquid fill line generates the vacuum in the fill line in the area of the vacuum passage. Until the level of liquid in the underground tank rises above the end of the vent passage, atmosphere from within the tank is drawn into the vacuum passage from the vent passage.
