Abstract: An elastic joint, in particular for a wheel suspension of a motor vehicle. The joint includes an inner armature, an outer armature surrounding the inner armature, wherein the armatures define an axial direction and two radial directions perpendicular to the axial direction as well as perpendicular to each other and disposed in a circumferential plane, and an elastomeric body for the mutual elastic retention of the armatures, wherein the elastomeric body consists of at least four connecting columns respectively extending from the inner armature to the outer armature.

Abstract: System for loading and unloading of cold media, for example LNG or LPG, to or from a vessel, through pipes (1) connected with ball joints, where the pipes are insulated, and when each ball joint's inside part (4) has an inside pipe (3) which is sealed against the inside part (4) substantially over the letter extent, and which thereby forms an inside annulus (6) which can be evacuated, and that each ball joint's outside part (10) is surrounded by an outside annulus (9) which also may be evacuated.

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 flexible pipe joint capable of joining connecting portions of connected objects such as pipes to each other while permitting the direction of joining between both to be varied as desired. First and second joint members (11,31) are formed with spherical inner surfaces (13,37) which slidably contact spherical outer surfaces (54,56) on an interpolating member (51) located between the joint members. Thus, the interpolating member (51) is rockable relative to the joint members (11,31) about the centre of each of the spherical outer surfaces (54,56). Press rings (16,40) are arranged to keep both spherical outer (54,56) and inner (13,37) surfaces in contact with each other through bearing balls (23,47).

Abstract: The spigot joint for metallic pipes, particularly for liquids comprises a protector for the lining of the pipe. The protector is associated with an end portion of the outer surface of the pipes.

Abstract: An insulating joint for pipelines comprises two metal tubular parts each having a dilated end portion, the dilated portion of one of the tubular parts being located within the dilated portion of the other tubular part and the dilated portions extending substantially parallel to each other so as to form a gap therebetween, two sleeves composed of an insulating material and forcefully introduced into the gap one after the other in a longitudinal direction so as to form a space therebetween, and a gasket located in the space and forcefully compressed between the two sleeves.

Abstract: A flexible joint assembly for interconnecting two conduits that transport fluid under pressure includes an annular housing and a tubular member of smaller diameter than the housing. The housing has an opening at each end, as well as two spaced apart, annular flanges that extend radially inwardly with respect to the housing. The tubular member has adjacent one end a flange which extends radially outwardly and which is disposed between the two flanges of the housing. The other end of the tubular member projects from an opening at one end of the housing for attachment to a fluid conduit. Between each housing flange and the flange of the tubular member is an annular flexible element that includes at least one body of elastomer. One side of one of the flexible elements is exposed to the pressurized fluid flowing through the conduits and the joint, while one side of the other flexible element is exposed to the exterior of the joint.

Abstract: A flexible joint for a conduit transporting fluid under pressure includes a pair of spaced rigid rings. An annular flexible element is disposed between and sealingly engaging the rings so as to define a pair of annular exposed side surfaces on the element. One side surface is exposed to pressurized fluid flowing through the conduit, thereby creating a pressure differential across the flexible element between its side surfaces. To resist the load that results from the pressure differential, the flexible element incorporates a body of elastomer that has a thickness between the rings which decreases from the one side surface of the element to the other side surface. The flexible element can thus resiliently accommodate relative motion between the rings, while providing a fluid-tight, pressure-resistant seal.
