Abstract: The racking arm includes a housing affixable to a tank side wall. A racking shaft extends through the housing with an inlet pipe coupled to an inside end of the racking shaft, with an entrance offset from a rotational axis of the racking shaft. A control arm is affixed to the racking shaft and can be rotated to cause rotation of the racking shaft relative to the housing and to change the entrance to different elevations within the tank. A clearance groove surrounds the inside end of the racking shaft to facilitate cleaning of the inside end of the racking shaft. The arm can interface with an indexing plate to hold the racking shaft fixed with the arm indicating by its position the orientation of the entrance. At least one leak detection port extends through the housing to indicate whether fluid is leaking between the racking shaft and housing.

Abstract: A pipe system has an elbow 70 with a snake-passing opening 72 (FIG. 3) that is normally closed by a plug 88, with the walls of the snake opening and plug constructed to avoid harmful wear during use of the snake. The elbow forms a nipple 82 that surrounds the snake opening. The nipple has threads (102, FIG. 4) on its outside so snake-caused wear does not initially occur in the threads. The snake opening has an axis 108, and the plug middle forms a cup 112 that extends axially inward to block a majority of the volume within the inner end of the nipple.

Abstract: A swage or coupling tool is provided for use in coupling a fluid line to a compression fitting, a fluid coupler, or the like. The swage tool provides multiple degrees of freedom and/or multiple pivots or pivot joints to facilitate and maintain alignment of the jaws with the compression fitting during use of the swage tool to facilitate properly-aligned assembly of the compression fitting, and to limit bending or kinking of the fluid line when the fitting is being attached. The swage tool includes a pair of movable jaws, which may have stepped or rounded engagement surfaces, which may be forced against corresponding engagement surfaces of the compression fitting to securely assemble the fitting to the fluid line. The shape of the engagement surfaces facilitates properly-aligned assembly of the compression fitting, and limits bending or kinking of the fluid line when the fitting is being attached.
