Abstract: A drain basin has a basin with walls and a cavity therein. The basin can have one or more sleeves coupled thereto. The sleeves are in communication with the cavity. The sleeves form pipe couplings to the basin. Each sleeve has a free end and a fixed end. The fixed end is coupled to the basin. The sleeve has an inside diameter that decreases toward the fixed end, which inside diameter is structured and arranged to receive the outside diameter of a small pipe. The sleeve also has an outside diameter that increases toward the fixed end, which outside diameter is structured and arranged to receive the inside diameter of a larger pipe. In addition, catches are provided to couple a corrugated pipe to the sleeve. The catches comprise fingers that flex or projections on ribs. Thus, the drain basin allows several diameters of several different pipes to be coupled to the drain basin.

Abstract: An open-ended coupler for joining a pipe to a larger opening defines a passageway having straight and angled sections. The straight section has a uniform inner diameter concentric about a centerline sized to receive the outer diameter of the pipe. The angled section has a narrow end with an inner diameter less than that of a wide end and of the straight section, and being at least as large as the inner diameter of the pipe. The angled section has an upper portion above the centerline that at least in part increases in radius from the narrow end to the wide end. A lower portion has a constant radius, at least along a line extending between the narrow and wide ends at a six o'clock position with respect to the open end of the angled section. A face groove holds an o-ring and an alignment tab fixes the rotational orientation of the coupler.

Abstract: In a connecting structure of a pipe of an air conditioning unit and a pipe joint for supporting the pipe, an insertion hole through which the pipe is inserted is formed within the pipe joint. The insertion hole has substantially a L-shaped cross-section and includes a first portion for receiving an end portion of the pipe and a second portion for receiving a flat portion of the pipe. The second portion is elliptical-shaped. In connecting the pipe to the pipe joint, the pipe is pressed into the insertion hole by a pressing punch. As a result, the pipe is bent and shaped along the elliptical shape of the second portion in the pipe joint, thereby forming the flat portion in the bend of the pipe. At the same time that the flat portion is formed, the pipe is clamped in the pipe joint.

The seal face segments may each have a nose that is held snugly by each holder half and is supported axially. Aligning pins received in aligning holes of the holder halves may be used to align the face segments. A fixture may be used to axially align the seal segments. A split o-ring and inner axial wall may be included that position the seal face concentrically with a shaft. Each holder half may have an integral band that clamps and also positions the face segments concentrically with the shaft. The walls of the holder halves may be stress-relieved proximate the junctions of the holder halves. A kit is provided for a rotary seal component with a rigidly mounted seal face. Another seal component includes a seal face comprising two seal face segments resiliently mounted in two holder halves.

Abstract: The invention relates to a fluid connector for sealing an interface between first and second fluid passages in a plasma processing apparatus.
