Abstract: An intake manifold flange system prevents leakage between joining portions of an intake manifold and a cylinder head while permitting stress relief. A flange body has an opening for receiving a distal end of the intake manifold and fastener hole openings for fixing the flange body to the cylinder head. Spaced annular grooves are arranged in an axial direction of the intake manifold. O-rings of a dimension to extend from the annular grooves and provide a pressurized contact with the distal end of an intake manifold. An annular groove is formed at a surface opposite a mounting portion of the cylinder head and an O-ring seal enables offsetting of the flange body from the cylinder head surface.

Abstract: A single-chambered static pressure device and method for supporting and protecting a human lower extremity and for normalizing the pressure and forces acting thereon includes an inflatable wrap or boot-like device having a single internal air chamber and including an interior plastic sheet and an exterior plastic sheet joined peripherally together forming said air chamber therebetween, a nozzle valve for admitting air into the air chamber, and fasteners for releasably securing the inflatable device about the lower extremity. The plastics sheets forming the single air chamber have a plurality of aligned openings extending therethrough and the sheets are joined about the circumference of each hole for providing heat and moisture dissipation, ventilation and visibility therethrough.
