摘要： There is provided a pipe joint between a first pipe end and a second pipe end. The pipe joint includes telescoping means allowing the ends to move axially with respect to each other while maintaining fluid-type communication. The joint also includes a plurality of contraction units located exterally of the pipe ends and the telescoping means. Each contraction unit includes a rod member with one end engaged with a first flange member fixed with respect to the first pipe end, while the other end of the rod member is secured to a piston riding in a cylinder with a cylinder bottom, the cylinder being engaged with a second flange member fixed with respect to the second pipe end. The cylinder bottom lies is between the piston and the previously defined one end of the rod member, and the cylinder is displaced axially away from the telescoping means. A fluid conduit connects the interior of one of the pipe ends with the cylinder volume lying between the piston and the cylinder bottom, so that the pressure inside the cylinder volume is a function of the pressure inside one of the pipe ends. This allows compensation for the expansion forces arising from pressure in the pipe joint, but does so with a structure in which the contraction units are not located directly opposite the telescoping means, thus facilitating disassembly for repair and other purposes.

摘要： This invention provides a pipe joint which includes a first pipe end and a second pipe end juxtaposed in substantial alignment. The pipe joint is capable of providing for movement of one pipe end with respect to the other, and also for pressure-compensation. A sleeve member spans between and externally of both pipe ends. Two annular ring structures are positioned between the pipe ends and respective ends of the sleeve member. Sealing surface engagement takes place between each annular ring structure, its respective pipe end, and the sleeve member. Articulating means are provided for interconnecting each annular ring structure with the opposite pipe end, thereby to permit the pressure-compensation.

摘要： A magnetic shaft guard for use with a rotating shaft has a permanent magnet to hold the guard in place on the rotating shaft. Sufficient clearance is present between the shaft and an inner diameter of the guard so that the guard will cease rotation freely relative to the shaft should external contact with the guard occur. The magnet is loosely mounted within a cavity near the tip of the shaft guard so that the magnet is able to cant and thereby adhere better to shafts with tips which are not squarely cut. A spiral or other design may be placed on the guard to visually alert persons in the vicinity that the shaft is rotating.

摘要： There is provided a spherical bearing arrangement within a pipe joint between a first pipe end and a second pipe end. The pipe joint is telescoping to allow the pipe ends to move axially, rotatably and genicularly with respect to each other, and includes the plurality of contraction units located radially outwardly of the pipe ends. The contraction units are connected between the pipe ends and are supplied with fluid under pressure so that they counteract the axial separation tendency between the pipe ends when the latter are filled with a fluid under pressure. The joint includes a hollow cylinder extending between the pipe ends, and the spherical bearing is in a form of a ring member snugly but slidably surrounding each end of the hollow cylinder and mounted thereon in a liquid-tight manner. Each ring member has a male spherical surface with its center of curvature located on the axis of the cylinder, and mating with female spherical seat means on the respective pipe end. The fluid within the pipe ends has direct access to part of each ring member adjacent its respective pipe end and thus exerts a first axial force on the ring member in the direction away from the respective pipe end. Further fluid conduit means are provided from the interior of one of the pipe ends to a part of each ring member remote from its respective pipe end, and thus exerting a second axial force on the ring member in the direction toward the respective pipe end. The axial projections of the areas of the parts of the ring member subjected to these forces are such as to make the first and second axial forces substantially identical, so that the ring member is in hydraulic balance.

摘要： There is provided a pressure-compensating pipe joint which includes sleeve members adapted to be affixed to respective lengths of pipe to be joined, and telescoping means which allows the sleeve members to move axially with respect to each other while maintaining fluid-type communication between them.A number of piston-type contraction units are located exteriorly of the sleeve members and of the telescoping means, and are connected to link members attached to the sleeve members. By placing the contraction units outside of the general telescoping arrangement of the pipe joint, replacement and repair of these units is a relatively simple matter.
