  • Patent number: 4909544
    Abstract: Apparatus for the transfer of material from one container to another container. The one container is placed in an attachment having a 45.degree. coupling joined by a straight bend to a fixed part with a 45.degree. second coupling. A motor rotates bend relative to the fixed part. Gears ensure an equivalent joint rotation of the attachment with respect to the bend. The one container is turned over and its content flows into the other container. This apparatus is particularly useful with polluting, toxic and radioactive products.

  • Patent number: 4903992
    Abstract: A connection assembly secured a running tool into a tubular casing hanger. The connection assembly includes a frusto-conical threaded section on a running tool and a nose section of cylindrical shape located below the threaded section. The casing hanger has a bore with at least one circumferential recess. A collet ring having internal threads is initially carried on the nose section. The collet ring lands in the recess when the running tool is moved into the casing hanger. Continued movement causes the collet ring to deflect outward. The collet ring has threads on its inner diameter that slide on the threads of the running tool to latch the members together. Slots in the collet ring enable the outward deflection to occur. A pin engages the collet ring to enable rotation of the running tool relative to the collet ring to unscrew the members from each other.

  • Patent number: 4903993
    Abstract: A tieback connector for connecting a conductor to a subsea wellhead mandrel utilizes two points of interference fit. The tieback connector has a tubular body from which depends a downward opening funnel. The mandrel has an upper bearing surface and a lower bearing surface, spaced apart by a cylindrical wall section. The lower bearing surface protrudes outward and is a frusto-conical surface. The mandrel has upper and lower bearing surfaces that are dimensioned to frictionally engage the upper and lower bearing surfaces of the mandrel as the funnel makes the final seat on the mandrel.

  • Patent number: 4903996
    Abstract: A coupling band for forming a pipe joint between adjacent ends of a pair of respective pipe lengths has an elongate fastener tongue at one end which is fed through a corresponding receiver at the other end of the band. The tongue and the receiver are provided with complementary ratchet-type teeth so that the tongue can be fed through the receiver in a band-tightening direction and so that the teeth will effectively hold the tongue within the receiver, preventing it from being withdrawn in a band-relaxing direction. A manually operated rotary ratcheting tool is provided for feeding the tongue through the receiver in order to tighten the band when forming the pipe joint. When the band has been tightened to the required extent, the ratcheting tool is removed and a leading end of the tongue which has passed through the receiver is bent back over the top of the receiver in the form of a hook providing additional security against release of the band.

  • Patent number: 4900065
    Abstract: A quick-connect fluid coupling for fluid conduits includes first and second identical inter-fitting bodies (10, 10'). Each of said bodies includes barrel portions (14) and sleeve portions (16). The sleeve portions include barrel accepting recesses (34). Each body portion also has a forward projection (48) including an angled ramp (50) and a step (52) and an opposed U-shaped latch (54). The body also has tubing accepting bores (26, 42) which accept ends of fluid conduit tubes. First and second fluid passages (30,46) extend through the body to the barrel portion and barrel accepting recess respectively. When the bodies are joined in opposed inter-fitting relations, the barrel portions on the first body are accepted into the barrel accepting recesses on the second body and vice versa. The step on the forward projection on the first body catches in the U-shaped latch on the second body and vice versa to hold the bodies together.

  • Patent number: 4895397
    Abstract: A clamp for forming a seal on a pipeline section, the clamp comprising a pair of complementary clamp members to be clamped together, each clamp member having an inner surface with a pair of axially spaced, circumferentially extending circumferential seals, and one clamp member having a pair of circumferentially spaced longitudinal seals which extend axially to bridge the gaps between the opposed circumferential ends of the pair of circumferential seals to define four junction zones where the circumferential seals and the longitudinal seals abut, and retention means at each junction zone to connect the circumferential and longitudinal seals together in the retention zones, and at the same time connect the seals to the clamp member at the junction zones. The clamp includes corner seals to provide back-up sealing for the junction zones. The clamp includes heat protection grooves to protect certain of the clamp seals. The clamp may include a pipe branch to provide a hot tapping facility.

  • Patent number: 4895395
    Abstract: Quick connector for flexible tubes or pipes, which comprises a hollow body, equipped on the inside with a seating for an annular seal, to which body is secured a collar carrying a conical elastic ring having radial slits open towards the inner edge, the ring diverging towards the free end of the body, into which conical ring there may be inserted a flexible tube in sealing contact with the annular seal, which tube can be advanced towards the interior of the hollow body with limited elastic deformation of the conical ring and in conditions of jamming of said conical ring when the tube moves outwards, there being also present a shell projecting outwards from the body and surrounding the flexible tube and having a tapered end towards the inside, the shell being in contact with the internal edge of the slit conical ring and being adapted for preventing, when pushed inwards into the hollow body, the jamming of the conical ring on the surface of the flexible tube, thus making its withdrawal possible.
