Abstract: A vessel for use in a refrigeration system. The vessel includes a vessel body and at least one end wall for closing the vessel body, the end wall having a threaded receptacle. The threaded receptacle is configured to accept a threaded fitting and the threaded receptacle includes: an annular sealing surface for engaging a corresponding surface of the fitting, the sealing surface formed on a first side of the end wall; and a threaded surface defined by an inside wall of an annular protrusion, the annular protrusion having a longitudinal axis disposed generally perpendicular to the sealing surface, and wherein the protrusion extends longitudinally from a second side of the end wall toward an interior of the vessel body.

Abstract: An adjustable sliding assembly. The sliding assembly includes an article sliding surface, the sliding surface having a proximal end pivotally connectable to a work surface and a free distal end; and a support member pivotally connected to the sliding surface between a midpoint of the sliding surface and the distal end of the sliding surface, the support member selectively holding the sliding surface in one of a plurality of inclinations and being actuated to progressively adjust the height of the distal end of the sliding surface in correspondence to the plurality of inclinations. Also disclosed are methods of stacking articles using the sliding assembly.

Abstract: A vessel (50) having a cylindrical wall (52) and an end wall (54). The cylindrical wall (52) includes an edge portion (58), a radially inward shoulder portion (60), and a capture portion (62) therebetween. The end wall (54) is interference-fit in the capture portion (62) with the shoulder portion (60) forming a positive stop therefore and the edge portion (58) being turned radially inward thereover. An inlet/outlet fitting (70) extends through an appropriately-sized opening in the end wall (54) and is secured thereto by, for example, a lip (72) and a weld (74). The vessel (50) can be incorporated into the construction of refrigeration components wherein compressor-generated vibration causes stress concentration concerns for inlet/outlet interfaces on the end wall (54).
