  • Patent number: 6499772
    Abstract: A radial conduit coupling is provided. The conduit coupling may include a tubular first connector having an exterior diameter, an interior diameter and first and second ends. The first end may be adapted to receive a first conduit. The second end may include at least one locking lug configured to cooperate with at least one shaped cavity associated with a component of a conduit system. The locking lug may extend from at least one tab lock disposed at the second end of the first connector. In one embodiment, a protrusion may extend from the interior diameter and generally separate the first end from the second end. The protrusion may include an interior diameter which generally corresponds to the interior diameter of the first conduit.

  • Patent number: 4385778
    Abstract: The subject of the invention is a device for compensating for the movement of the pipelines which supply two separate gaseous agents to an industrial revolving appliance. The device possesses two independent systems of compensation positioned coaxially such that an external conduit movement compensation assembly is positioned relative to the external conduit. Each of the compensation assemblies possesses a packing comprises the body (15) and (25), the sealant (16) and (26) placed inside it and the gland (17) and (27) and two elastic collar-type articulated joints comprises elastic collars (19) and (29) and spacing rings (20) and (30), holding rings (21) and (31) and fastening rings (22) and (32).

  • Patent number: 4355827
    Abstract: A swivel joint for connecting together a pair of pipes and for transferring fluid between the pipes at ambient temperatures and at cryogenic temperatures. A cryogenic seal between the joint's relatively rotatable inner and outer elements prevents fluid leakage at cryogenic temperatures, and an ambient seal assembly between the joint elements provides a seal at ambient temperatures and prevents fluids from contacting the cryogenic seal. The ambient seal assembly includes an elastomeric O-ring retained in the outer element, and an annular sealing ring fastened to the inner element and spring-biased towards the O-ring. At ambient temperatures the sealing ring is held against the O-ring in a fluid-tight manner. As the temperature decreases, a plurality of rods or wires, or an annular sleeve, having a high coefficient degree of linear expansion, contracts and pulls the annular sealing ring away from the adjacent O-ring to prevent wear of, and other damage to, the O-ring at low temperatures.
