Abstract: A pump assembly for use within a high pressure pumping system includes housing, a head and a base. The housing contains at least one centrifugal pump stage. The head and base are attached to the housing with corresponding internal threaded connections. The head and base are further retained to the housing with corresponding external flanged connections. The external flanged connections provide redundant connections that reduce the risk of separation between the housing and the head and base.

Abstract: A coupling apparatus and method for coupling two duct sections together to form a joint therebetween. The apparatus includes a catcher ring component formed coextensive with the edge of one section of duct, and a catcher finger component formed coextensive with an edge of the other section of duct being coupled to form the joint.

Abstract: There is provided a spring comprised of a wire which includes an elastic, coiled central portion and opposing end portions formed as hooks. Each hook terminates in an end having a hole therethrough. The spring is useful with an exhaust system of the type having a pair of sections joined but not affixed to one another to thereby form a flexible joint. A loop is fixedly connected to each section adjacent to the joint. The opposing hooks of the spring are securely received by the loops, and a safety wire is received through the hole in the end of each hook and secured to the corresponding loop. In an aircraft having an exposed exhaust system, the safety wire prevents a broken spring or loop from impacting and damaging vital components of the aircraft, particularly a pusher propeller positioned to the rear of the exhaust system.

Abstract: A quick coupler retention clip is disclosed for preventing an inadvertent disconnection of a quick coupler. The clip device includes a unitary clip having a first and a second end. The first end of the clip is of annular configuration so that the body of the coupler extends through the annular first end for anchoring the first end of the clip relative to the body. The second end of the clip is a C-shaped configuration to removably engage a groove defined between a collar and the body of the coupler. A strap extends between the first and second ends of the clip for securing the first and second ends of the clip together. The disconnection of the body from the port of the quick coupler is permitted only when the C-shaped second end is removed from engagement with the groove so that inadvertent disconnection of the body from the port is prevented.

Abstract: A high pressure flow line that is formed from sections of pipe that are coupled together is provided with a safety restraint assembly. The safety restraint assembly is formed by wrapping short, flexible rib tethers around the pipeline near the ends of each section of pipe. A plurality of long tethers are linked end-to-end to form a continuous spine, which is threaded through all of the rib tethers. Each of the tethers contains continuous filaments. The spine is then anchored at each of its terminal ends to suitable anchoring structures. Alternatively, the safety restraint assembly may utilize anchor elements in addition to the tethers.

Abstract: The present invention is a flanged connection repair device and method for flanged pipe joints and the like that produces axial compression against the flanges of the joint so that the flange bolts may be removed and replaced, while simultaneously producing radial pressure on the sealant between the flanges, mechanically and radially compressing the sealant into the joint, directing the sealant around the full perimeter of the flanged joint. By providing both axial and/or radial compression the invention stops leaks in the pipe without interrupting the use of the pipe, duct work, and the like, and can be used permanently or temporarily, repeatedly, and under a variety of conditions including moderate to high internal pressures, vacuums, and temperatures.

Abstract: An adaptor for use with dockside pumps to facilitate pump out of sewage holding tanks is constructed so that it readily accommodates both of the two most common fittings for dockside pumps, an elastomeric material right circular cone frustrum, and a cam actuated fitting having a number of curved locking surface locking cams. The adaptor is a tubular body of rigid material having first and second ends with a concentric bore. An interior surface of the first end defines a cone frustrum cooperable with the dockside pump cone frustrum fitting, and the exterior surface of the first end is a cylindrical surface with a semi-toroidal recess at a central axial portion, which recess cooperates with the curved surfaces of the locking cams. The second end of the adaptor has external threads that fit one of three common sizes of boat deck fitting internal threads (e.g.

Abstract: A casing scraper for well casings in which the scraper blades are positively held on the scraper body. The blades are provided with retainer arms which engage a series of splines formed integrally with the scraper body, and slide up the splines to a cutting position. The blades are held in place by a retainer ring which has two sets of threads, with a gap in between the two sets. The lower set of threads normally engages annular threading on the scraper body to bear against the lower end of the blades and hold them in place. If the ring becomes partially unscrewed, the gap between the two sets of threading tends to resist further disengagement, and the ring remains sufficiently in place to prevent the blades from unloading. The orientation of the ring threading and of the annular threading is also reversed from the scraper's direction of rotation in normal use, so that under normal rotation the ring is urged to rotate more tightly against the blades, rather than to unscrew.

Abstract: A device used to restrain the flying or whipping of hoses that are accidentally detached while under pressure. The device is formed of a cable halter having slip knot type snares at each of the extremities for engagement about the hoses at a position on both sides of the expected place of separation, a pair of springs forcing the snares to close, so as to obtain a tight engagement with the hoses, and a safety fastener adapted to lock together the hose connectors. The safety fastener is connected to the cable halter by means of a secondary cable, which encircles the hoses to keep the halter cable close to the hoses.

Abstract: A tether adapted for use in a device for inflating and deflating an inflatable article. The device shown has a body affixed to a wall of the inflatable article at a hole therethrough, the device having a tubular insert or nipple sealed to the body and a closure element or plug functioning as a stopper for the nipple, the plug being completely removable from the nipple to deflate the article. The plug has threaded engagement with the nipple, and functions as an inflating check valve when the valve is opened by partially unscrewing the plug from the nipple. The inflation device incorporates a novel tether for the rotatable plug, the tether permitting free rotation of the plug with respect to the nipple, and the complete removal of the plug from the nipple while retaining it tethered, as during the deflation of the inflatable article.
