Abstract: An improved enclosure including the use of a seamless urethane gasket which is continuous and formed in situ on a planar surface, with no requirement for the gasket to be formed in a groove or for additional backing structure to be added. The enclosure also includes the use of concealed hinge with cutouts positioned on the door to permit at least a 180.degree. swing. The hinges are located outside of the sealing surface and do not overlap it, permitting the entire opening to be used, such that a full front window may be incorporated into the door without interference from the hinges.

Abstract: A cable supporting structure includes a longitudinally extending channel-shaped support structure having a pair of spaced side walls with free end portions turned inwardly to form opposed longitudinally extending flanges. A locking strap has opposite end portions and an intermediate portion therebetween. A support member is positioned within the support structure to extend between the side walls with opposite ends thereof respectively supported by the flanges. The support member includes a pair of slots for receiving the locking strap to cause the intermediate portion to extend around a central body portion of the support member in overlapping relation therewith. The support member includes resiliently deflectable extensions at the ends thereof for producing frictional contact between the support member and the side walls tending to resist movement of the support member within the support structure.

Abstract: A conduit support includes a longitudinally extending channel-shaped member having a pair of spaced apart side walls. The side walls have free end portions turned inwardly to form opposed flanges that extend the length of the conduit support. A rigid buckle-like member is positioned within the conduit support so as to bridge the opposed flanges. The rigid member is supported by the flanges for slidable movement to a selected position along the length of the channel support. The rigid member includes a body portion having a plurality of fingers forming a first slot and a second slot extending through the body portion and spaced from one another. Each slot includes an open end portion and a closed end portion, thereby forming parallel, spaced apart arms connected by a bridge section. A flexible locking strip or cable tie of a preselected length extends upwardly through one of the slots across one of the arms and through the other slot and into surrounding relation with a cable.

Abstract: A tubular fitting is threaded at one end for connection to a valve, meter, or the like and at the opposite end to a compression nut. A bore extends through the fitting and includes a tapered or restricted portion. The tapered portion forms an internal shoulder. A compressible sleeve is positioned in the fitting bore opposite the internal shoulder. A reinforcing insert extends through the sleeve. The insert abuts the end of the sleeve. An annular space is provided between the sleeve and the insert for receiving an unthreaded conduit. The insert includes a plurality of annular serrations adapted to frictionally engage the end of the conduit positioned in the annular space. The application of a force on the conduit in a direction to pull the conduit out of the fitting advances the sleeve against the fitting internal shoulder. The sleeve is compressed onto the flexible conduit to increase the frictional engagement of the conduit with the insert serrations.

Abstract: A first clamp member and a second clamp member are positioned in opposed spaced relation with a conduit, pipe or the like, positioned therebetween.

A pair of apertures extend through the clamping member. A pair of resilient polymeric annular flanges extend upwardly from the upper surface of the clamping member and around the apertures. The U-bolt threaded ends extend upwardly through the apertures. A pair of polymeric nuts engage the threaded ends above the annular flanges of the clamping member. A resilient sealing flange extends radially from the open end of each encapsulated nut.

Abstract: A cable connector includes an insert having a tubular body portion with a conical end portion longitudinally spaced from an annular flanged end portion by diametrically opposed radial grooves. The insert is positioned in an aperture extending through a wall of an electrical junction box. The tubular body portion is contractable to permit the wall surrounding the aperture to be positioned in surrounding relation with the grooves to retain the tubular body portion in the aperture. A passageway extends through the tubular body portion and includes a rectangular inlet and a rectangular outlet. Vertical sidewalls of the passageway diverge outwardly from the inlet to the outlet so that the cross sectional area of the outlet is greater than the cross sectional area of the inlet. A pair of wedge shaped members are positioned in the passageway to secure a cable, such as an insulated conductor, extending through the passageway from being pulled out of the junction box.

Abstract: A tubular body portion has an internally threaded portion and a cylindrical portion and includes an annular recess portion therebetween. The annular recess portion includes a first shoulder adjacent the threaded portion and a second shoulder adjacent the cylindrical portion. A circumferential cutting edge portion is provided at the juncture of the second shoulder and the adjacent cylindrical portion. A first conduit to be joined is extended through the cylindrical portion into substantially abutting relation with the first shoulder. A suitable expanding tool expands the end portion of the first conduit outwardly into the annular recess portion and against the cutting edge to produce a distinct gouge or circumferential cut therein. The coupling remains rotational relative to the first conduit with the end portion thereof expanded into the annular recess portion. A second conduit to be joined is threadedly advanced into the threaded end portion of the coupling by rotation of the coupling.

Abstract: A molding apparatus for applying a protective coating to an irregularly sized article includes a mold shell having upper and lower portions with mold cavities of a preselected configuration in each portion to receive the article, such as a threaded fitting or coupling, for coating. The shell upper and lower portions are secured together to position the cavities in overlying relation and surrounding the article. Openings extend through the shell portions into the overlying cavities to expose the end portions of the article. Seal members are advanced into the openings and are secured as by threaded engagement to the end portions of the article. The seal members seal the openings and position the article within the cavities to form an annulus surrounding the article as defined by the surface of the cavities. A fluid inlet extends through the shell and into the annulus.
