Abstract: The present invention is embodied in a sprinkler head adaptor assembly including a sprinkler head adaptor having a generally cylindrical shape and a female threaded interior wall in a central aperture for receiving a male threaded sprinkler head. The sprinkler head adaptor includes an exterior surface that includes an exposed portion. The assembly includes a pipe extension formed from an injection moldable material with a length suitable for spanning a distance from a pipe system to sprinkler location that is formed integrally with the sprinkler head adaptor, wherein the exposed portion of sprinkler head adaptor is sized and shaped for engagement with a wrench. A metal ring maybe formed in the central aperture.

Abstract: The present invention is embodied in a pipe coupling device for joining two pipe segments including a cylindrically shaped gasket for receiving the pipe segments and a cylindrically shaped clamp having a first and second semi-cylindrical segment attached by a hinge that extends along a length of one side each segment parallel to the axis of the cylinder. The clamp includes an inner wall having at least one groove forming a channel aligned in each of the semi-cylindrical segments and extending about the circumference of the inner wall of the clamp. A second side of the semi-cylindrical segments includes flanges that extend radially away from the segments. The flanges include complementary apertures and bolts that are received through the apertures for sealing the flanges together.

Abstract: A light-weight, portable display system which includes plural, hollow, plastic panels having uniquely contoured corners. The panels may be of flat or curved configuration. Most of the plastic panels are fabricated to present smooth front and rear faces. However, some panels are made with at least one slotted face for supporting shelves therein. Straight plastic connector components are designed to accept the corners of the panels, thereby connecting the panels in a manner to form a display area. Hinged plastic connectors are provided so that adjacent panels may be arranged at angles ranging from ninety to one hundred eighty degrees.
