Abstract: A cap and shield assembly for a fluid conduit coupler has a shield and a cap hingedly connected to the shield with a shaft having a cross-pin extending therethrough. A cam bushing in the bore of the shield has a cam surface which coacts with the cross-pin to provide a positive closed position for the cap relative to the shield. Preferably, the cam bushing also provides a positive open position. The cap and shield assembly is particularly advantageous for couplers having a dry-break interface because the cap is readily moved between open and closed positions and operators will be more inclined to use the cap after fluid transfer. Shrouds on the cap and the shield coact to protect the coupler interface when the cap is in the closed position thereby protecting the dry-break interface from contamination by road and environmental debris. This is particularly advantageous compared to the dust cap of the prior art which tends not to be used for its intended purpose of protecting the fluid conduit coupler.

Abstract: A method for converting a gate panel into a rolling cantilever-type gate utilizing a conversion kit consisting essentially of a one-piece top-rail extrusion, commercially available roller assemblies, and hardware for attaching the top-rail extrusion to the existing gate panel.The top-rail extrusion is constructed in one piece with a flat vertical ribbed side face having vertical shoulders. The shoulders either bolt directly to the gate panel in a horizontal orientation or attach to the gate panel horizontally with contoured brackets selected to fit the gate's structural members. One side of the top-rail extrusion is provided with a longitudinal compartment having a downward facing opening along its length. The compartment serves as a trackway for upper roller assemblies which are secured to support posts. The upper roller assemblies access the compartment by way of the downward facing opening and support the gate.

Abstract: A door hole cover for covering a hole in a door has two substantially flat cover plates that are secured to opposite sides of the door for covering the door hole. The first cover plate has an attachment tube extending from the center of its inner surface such that the attachment tube is positioned inside the door hole during assembly. A centering disk is placed over the attachment tube and held in place by a retainer clip. A fastener fits through a hole in the second cover plate and engages an internally threaded hole in the attachment tube to secure the first and second cover plates to the door in a position covering the door hole. The centering disk inside the door hole substantially prevents movement of the cover plates in a plane that is parallel with respect to the door. The centering plate may include three removable tabs that are left in place to cover relatively large door holes, but may be removed to cover smaller door holes.
