Abstract: The invention relates to a hydraulic coupler. The coupler comprises a male and female coupling, each with a poppet valve moveably supported by an inner surface of a main body of the coupling. Each coupling further comprises a movable connector part in its front end with a spherical rear surface accommodating a spherical connector seat in the main body, where the connector is provided with sealing means between the connector part and the main body of the coupling.

Abstract: In an apparatus having at least one first hollow element for conducting a fluid having a connection element, to enable and facilitate a simple and reliable connection to a second hollow element, a snap-in element of the connection element having a latching surface which contacts an abutment surface in a connection state with the second hollow element is made as a radially widenable snap-in ring.

Abstract: The tube (60) includes first and second portions (66, 58) that each have mating spherical sections (82, 84) at adjacent ends (72, 74) of each portion (66, 68). The second portion (68) includes a spring sleeve (92) configured to surround an outlet end (72) of the first portion (66). A spring (102) is captured inside the spring sleeve (92) and secured between a retaining clip (100) and a shoulder (88) protruding from the exterior surface of an outlet end (72) of the first portion (66) to maintain fluid seals between the spherical sections (82, 84). The spherical sections (82, 84) permit slidable motion relative to each other thereby facilitating rotational and angular motion between the tube portions (66, 68). One of the two portions (66, 68) may include a telescope mount (110) to permit limited axial motion of the tube (60).

Abstract: A knuckle joint 18 for the exhaust system of an internal combustion engine comprises first and second pipe segments 20, 22, the second pipe segment having an outwardly deformed end portion 24 which enters with clearance into a flared end portion 26 of the first pipe segment. There is a flange 32 on the first pipe segment and a flange 34 on the second pipe segment. A plurality of circumferentially spaced bolts 36 pass through corresponding holes in the flanges, there being a nut 40 on each of the bolts. On each bolt there is a coil spring 38 between the flanges, and a coil spring 42 between the flange 32 and the nut.

Abstract: The present invention relates to a ball joint mechanism which is adapted to permit setting of two members relative to each other, said members forming part of a settable device for gas transport, whereby one of said members preferably consists of a gas conduit and the other member preferably of a nozzle which is connected with said gas conduit and settable in various positions in relation thereto.

Abstract: The fire extinguisher bottle is intended for a vehicle or other moving structure and is clamped in a horizontal position. The outlet is ducted to locations where the fire extinguisher fluid may be required, such as the engine compartment and/or passenger compartment. The pick-up tube in the bottle is ball-and-socket mounted so that it is gravitationally carried to the bottom of the bottle no matter what the vehicle orientation.

Abstract: A novel quick disconnect ball joint coupling which utilizes as a misalignment ball locking mechanism, a combination of a plurality of locking balls and a locking sleeve. The locking sleeve provides an annular race or groove for receiving the locking balls, thereby obviating the high stress point-to-point contact problem associated with prior art locking ball techniques, but still provides the advantage of high speed, low torque rotation available with the use of such locking balls. More specifically, in the present invention, the locking balls do not come in direct contact with the misalignment ball, but are instead positioned in an annular groove on the exterior surface of the locking sleeve between the locking sleeve and the quick disconnect releasing sleeve. The locking sleeve is preferably spring loaded so that upon rotation, the locking sleeve remains stable with respect to the misalignment ball, thereby gaining the benefits of the low friction of a ball and race configuration during rotation.

Abstract: Sewage manholes having a deteriorated or defective manhole housing which is subject to undesired ground water infiltration are rehabilitated by inserting annularly expandable tubular sleeve assemblies partially into each inflow and outflow pipe of the manhole, connecting the sleeve assemblies to one another via an annularly-closed tubular conduit or network of tubular conduits and then sealing the sleeve assemblies to the inflow and outflow pipes and to the tubular conduit or conduits to form a fluid flow path between the inflow and outflow pipes which is sealably enclosed against water infiltration and sewage exfiltration.

Abstract: A remotely-operable connector comprising a pair of female end fittings, each adapted to be permanently fixed one to each of a pair of pipes to be coupled together, and a jumper assembly having a jumper pipe terminating at opposite ends in male end fittings which are received one in each of the female end fittings. Each mating pair of male and female fittings is received in a pivot housing which is mounted for universal articulation on the female fitting for enabling the housing to be angularly aligned with the end of the male fitting which is received in the female fitting.

Abstract: A Swivel Joint for use on producing wells which are being pumped, having an upper and a lower annular member, in juxtaposition, with a coil spring separating the members, the lower member having a curved external face to receive, in line contact, the inside wall of the retaining member, which is engaged with the upper member, and having a packing chamber and a packing nut having one end extending into said packing chamber, and a grease chamber in said packing nut, and packing members mounted in said packing chamber compressed by one end of said packing nut.

Abstract: A swivel assembly comprises a housing having a bore extending therethrough along a central axis. The housing has an end wall with an opening about the axis extending therethrough. A generally spherical swivel member is rotatably and swivelly disposed in the bore and includes an extension protruding through the opening. The portion of the extension within the opening is substantially smaller in transverse cross-section than the opening to permit limited swivel movement of the swivel member in the housing. The bore has first and second sections. The first section has a smaller diameter than the second section and thereby forms a wall. A stiff resilient element is provided between the wall and the swivel member for preventing movement of the spherical swivel member when subjected to a heavy load.

Abstract: The invention pertains to a rotary joint wherein pressures imposed upon the joint by the pressurized medium therein are internally compensated. The joint is characterized by its ability to accommodate axial drum expansion, minimize rotative friction and the major joint components are self-aligning with respect to rotary motion. The basic components include a body member receiving an end of a nipple member, one of the members being fixed against axial displacement. A single annular nipple seal mounted upon the nipple member within the body member chamber engaging a seal ring constitutes the sole mechanical connection between the body and nipple members, and the fact that the nipple seal is axially displaceable upon the nipple member permits an internal compensation of axial forces produced within the joint, permits accommodation of axial thermal expansion of the joint components, and the spherical configuration of the nipple seal provides self alignment between the body and nipple members.

Abstract: An angularly adjustable liquid outlet nozzle for directing a stream of fluid under pressure into a body of fluid has a unitary body with an inlet opening at one end communicating with a mixing chamber through a venturi air inlet, and an outlet opening at the other end in which is seated a directional ball outlet between a pair of low friction bearing and sealing rings. A spring maintains a sealing engagement between the low friction rings and the ball outlet so that the latter may be directionally adjusted without interrupting the seal.

Abstract: An adjustable shower head has a pivotal attachment of the body of the shower head to a conventional swivel or ball member which includes a releasable retainer interlocked to the shower head in a tamperproof manner. At the discharge end of the shower head there is a removable spray forming member and means for creating water pressure behind the spray forming member to maintain it in an appropriate spray forming position.
