Abstract: An adjustable floating seal piston type pressure regulator valve of the type wherein a spring biased piston engages a floating seal in a regulator body valve chamber to open and close a valve seat outlet in the valve chamber. The valve seat comprises a separate member from the regulator body and is adjustably movable in the valve chamber toward and away from the piston, such that movement of the valve seat toward the piston serves to lower a regulated outlet pressure and movement of the valve seat away from the piston serves to increase the regulated outlet pressure. The valve seat member is moved by an adjustment screw that is externally accessible by an adjustment tool. A tubular expansion chamber surrounds the regulator body and provides an enlarged expansion chamber that reduces valve recycle time. Convolutions or ribs in the expansion chamber housing enhance heat through transfer to the valve gases.

Abstract: An adjustable home entertainment cabinet for enclosing television sets of different sizes comprises a pair of movable tower cabinets and a bridge assembly that extends between the cabinets. A center section of the bridge rests on the tops of the cabinets. A bookshelf or shelf box is mounted on an underside of the center section. End sections movably mounted on the center section extend downwardly to cover gaps between the bookshelf and the inner sides of the tower cabinets. The center section includes a cornice molding that matches and is aligned with cornice molding on the tops of the tower cabinets. The end sections have a matching cornice molding that overlays and conceals the gap between the cornice moldings on the end sections and tower cabinets. Free standing television sets can rest on the floor. Table model sets and monitors can rest on free standing TV stands/storage cabinets of different widths that fit snugly between the tower cabinets.

Abstract: A connector for interconnecting vertical panels of adjacent cabinets comprises male and female connector elements releasably mounted in opposed openings in the sidewalls of adjoining cabinet modules. Each connector element comprises a body that is shaped to fit into a compatible opening in a sidewall of a cabinet. The body desirably has locking tabs extending radially outwardly therefrom. The locking tabs fit into the opening in the sidewall and then are rotated into locking slots in the sides of the openings. A projection with an enlarged head on the male connector element fits in a keyhole slot in the female connector element to lock the two connector elements together.
