    Abstract: A female component for a tubular hydrocarbon working string subjected to dynamic bending strength includes a tapered female threading cooperating with a male threading to form a rigid mutual connection of tubular elements, a free end and female sealing surface disposed between the free end and the female threading, the female sealing surface to contact in a made up condition with a male sealing surface to form a metal-metal seal, and an annular groove provided between the free end and the female sealing surface, leaving an axial distance greater than zero between the free end and a transition region outwardly of the female sealing surface, and a radial distance greater than zero between the female sealing surface and a chamfer at the free end, the groove including borders formed by the chamfer and a portion of the transition region protecting the female sealing surface prior to makeup.

    Abstract: A torque-less threaded connection is shown for connecting a drill tool to a drill string for use in horizontal directional drilling operations. An up-hole end portion has a female, box end opening with a non-threaded, slightly tapered first circumferential surface having a first median inner diameter; a non-threaded, slightly tapered second circumferential surface having a second inner diameter that is larger than the first diameter. A threaded tapered section extends between the first and second circumferential surfaces. The threaded tapered section has threads thereon which make up a multi-lead thread form. The downhole end portion of the coupling has mating external pin surfaces for engaging the internal surfaces of the up-hole end portion. A torque collar slides over portions of the up-hole and downhole end portions and prevents relative rotation between the downhole and up-hole portions and prevents toque from being transmitted to the threaded portions of the connection.

    Abstract: A rapid-connect coupler includes: an end fitting for conveying a fluid stream; a probe for conveying the fluid stream; a valve configured to occupy a closed position blocking fluid communication between the probe and the end fitting and an open position enabling fluid communication between the probe and the end fitting; a handle configured to actuate the valve between the closed and open positions; a sleeve moveable between a first sleeve position and a second sleeve position. The sleeve, in the first sleeve position, is configured to prevent the handle from actuating the valve from the closed position to the open position.

    Abstract: An embodiment of the invention is a cryo-connector, a connector that allows for the delivery and return of a cryogen in an axial configuration. In one embodiment, the connector is a tri-axial configuration allowing for the delivery and return of pressurized cryogen as well as the application of an independent vacuum in the third lumen. Various configurations, however, may accommodate any number of luminary spaces such that cryogen (or other fluids) and/or vacuum spaces may be created in a fashion complementary to the components that the connector will affix to and interconnect with. The connectors can be utilized with any low temperature, cryogenic device and at varying pressures.
