  • Patent number: 7744344
    Abstract: Vanes are generally hollow with a passage through which service pipes extend. These service pipes must be connected such that they can allow for thermal expansion and contraction but also anti rotation features are needed in order to prevent damage when a supply coupling is connected through a pipe end. This anti-rotation feature is generally provided between a top hat and a pipe end through flanges. In order to allow reduced spacing between the top of the vane and a casing the flanges are arranged to allow at least recessing of a first flange into a passage opening profile whereby those flanges inter-engage with second flanges at a surface interface to prevent rotation.

    Abstract: The system permits two tubular parts (1, 2) to be assembled, the assembly being able to be locked or released, without a cumbersome device being required. It includes in particular a toothed crown (10, 20) on each of the two tubular parts (1, 2), each with a series of teeth (11, 21) disposing of straight radial shoulders (12) on the first toothed crown and angled shoulders (22) on the second toothed crown. This assembly is completed by a locking ring (30) disposing of teeth (31) designed to fit between the shoulders (12, 22) of the two crowns, once they have interlocked. Turning the locking ring (30) allows, using the angled locking faces (33) of the teeth (31), the two tubular parts (1, 2) to be locked together. A locating ring (40) may be used to center the parts and receive the shear loads due to a transversal mechanical change.

  • Patent number: 5431507
    Abstract: A torque transmitting, bicycle frame coupling which connects to the frame tubes, replacing a portion of those tubes and having teeth on their engaging faces. Proper installation of two such couplings allows up to a 25 inch men's style bicycle with up to 700C (26 inch rim diameter) wheels to be cut in two pieces so that it fits in a suitcase with a combined height, width and girth measurement no larger than 62 linear inches and then be put back together with no loss of original frame geometry or stiffness. Each coupling is actuated, pulling the bicycle pieces together and joining them through use of specialized teeth under compression by a threaded lug, a removable-shoulder lug with a removable shoulder and a threaded coupling nut. The removable shoulder makes the nut and shoulder replaceable, and makes possible an additional shoulder on the tube connecting end of the removable-shoulder lug to keep the nut from slipping onto the frame and scratching the paint.

  • Patent number: 5349738
    Abstract: Cylinder-to-cylinder attachment method and construction featuring nonutiltion of mechanical fasteners or bonding, especially advantageous for attachment of cylinders which are composite or to be subjected to hydrostatic pressure. A fastening ring is interpositionally and rotatively engaged and aligned with a toothed axial end of each cylinder whereby the inwardly radial teeth for each cylinder appropriately mesh with the outer grooved circumferential surface of the fastening ring. The resultant joint is easily detachable and less susceptible than conventional joints to damage, breakage, degradation, stress concentrations and fluid infiltration.

  • Patent number: 5306052
    Abstract: In a compression type union for compressing two tubing segments against an intervening washer, a male nut, a female nut, and a pair of caps, the caps having interengaging tongues and slots. The nuts bear against respective caps, and the caps bear against respective heads of the tubing segments. The caps being non-integral with either tubing segment or with either nut, and there is no interengagement of any kind between the nuts and the tubing segments. The union can be joined without concern for positioning either of the nuts.

  • Patent number: 5007490
    Abstract: A downhole drilling apparatus which includes a progressive cavity drive train comprising a progressive cavity device and a coupling for converting the complex motion of the rotor into simple rotation. The coupling includes two shafts coupled to one another by joint assemblies connected to opposite ends of an intermediate shaft. The joint assemblies include interleaved annular extensions from the opposite ends of the joint assembly and an elastomer filling the spaces between the annular extensions. The elastomer is highly restrained by the interleaved annular extensions, but is still flexible in shear. The moving components within the coupling are perfectly isolated from the surrounding environment; the joint assembly may further include backup features such as a thrust bearing member and radial pins locking the interleaved portions together.

  • Patent number: 4821818
    Abstract: The present invention comprises first and second auger sections having upper and lower ends. The lower end of the first auger section is detachably secured to the upper end of the second auger section. The lower end of the first auger section includes a collar having axially extending indentations and projecting therein. The upper end of the second auger section includes a similar collar having axially extending projections and indentations therein. The two collars are matingly interlocked to prevent rotation of the augers sections with respect to one another. A detachable coupler surrounds the interlocked first and second collar means and holds them against axial movement away from one another. A seal causes the two ends to be sealed with respect to one another so that fluid cannot enter the internal bore of the tube sections.

  • Patent number: RE38204
    Abstract: A quick-connect coupling for interconnecting only matching fluid delivery and supply lines while preventing the inadvertent connection of mismatched lines where there are matched and mismatched delivery and supply lines. The coupling includes first and second coupling members that are releasably slidably, axially interfitted with their passageways in fluid communication. In the disclosed embodiment of a coupling for use in a chemical extraction system, one coupling member is a male member connected to the supply lines in the typical fifty gallon drum and the other coupling member is a female coupling member connected to the delivery lines. Key coding elements on the coupling members are movable into matched interengagement when the supply and delivery lines are matched but are precluded from moving into matched interengagement when the lines are mismatched.
