Abstract: A gasket includes a first slope at a first axial end. The fluid device includes a second slope that contacts the first slope. The first slope and the second slope have different gradients. The first slope allows at least the first axial end to be deformed along the second slope. The first slope contacts the second slope with a gradient that varies depending on a gradient of the second slope to seal a gap between the first slope and the second slope.

Abstract: A universal pipe joint for attaching two round pipes together accommodating misalignment using a female adapter fitting (30) engaging a male adapter fitting (44), each having a radial interior and exterior diameter (38) and (50) with a compression nut (52) urging them together. The female fitting has external threads (40) with a number of locking grooves (42) at right angles to the threads, and a compression nut with a spring-loaded ball (54) therein that clicks into the grooves while the nut is being tightened. When the nut is fully tightened, the radial diameters are compressed and the ball (62) is locked into the groove with a set screw (66). Thus securing the connection and eliminating loosening by over the road operation of a vehicle to which the device is attached. A second embodiment replaces the compression nut with a pair of flanges (68) held together by nuts and bolts.

Abstract: A connector for coupling pipe sections which may be either aligned or misaligned axially, the connector having a male fitting, a female fitting which mates with the male fitting and a retaining means which can be connected to the female fitting to hold the male fitting in place against the female fitting. In one embodiment, the retaining means comprises a hammer nut which has a retaining surface. The retaining surface of the hammer nut contacts a rear surface of a first one of the flanges for urging this flange forward. The hammer nut has threads which are complementary to a set of threads on the second flange. When the hammer nut is threaded onto the second flange, the first and second flanges are pulled together. The retaining surface of the hammer nut and the rear surface of the first flange have complementary spherical shapes so that the hammer nut can rotate and swivel with respect to the flange.

Abstract: The inlet nozzle suitable for swimming pools is constructed as a two-piece-spherical body. This is pivotally graduated on a seating ring and equipped with a continuous bore. One part of the spherical body is, with respect to the other, rotatable about the one axis which runs eccentrically with respect to the axis of the bore. Thereby the cross-section of the bore can be changed at the transition point between both bore sections by turning of the one part of the spherical body. Between the two parts is a gap through which air from the air pipe is introduced.

Abstract: For mounting a showerhead or the like to a pipe, a pivot ball is formed entirely of plastic material. It has a base internally threaded to attach to the pipe and a hollow shell coupled to the base so as to constitute the spherical portion of a ball joint. That spherical portion is composed of first and second mating approximately semi-hemispherical segments. The first segment is formed integrally with the base and the second segment is coupled to that base in establishment of the spherical ball. An internal tube extends from the second segment essentially through the entire assembly. In a second version, the internal tube is shorter but also serves to secure the two segments together. This version has a base which is externally threaded. Still another version has a different form of mating between the segments.
