Methods and apparatus are provided for obtaining a secure mechanical connection and a pressure-tight seal in the overlapping area of two telescoping tubular bodies. The two bodies, including the overlapping area, are radially expanded to increase the inside diameter of the bodies. The expansion forces an annular seal in the overlapping area into a pressure-sealing engagement between the bodies. A string of pipe assembled from joints secured to each other by telescoping, threadedly engaged expanded pin and box connections may be radially expanded into a surrounding well bore to provide a cased well having an internal diameter greater than the original internal diameter of the pipe string. The seal in the connection comprises an annular elastomeric seal ring and an annular Teflon spacer ring carried in a specially dimensioned groove formed in either the box or the pin, or both members of the connection. Radial expansion of the connection causes axial contraction of the groove, which acts with the spacer ring to expand the seal ring radially to seal the annular space created between the expanded pin and box.

Further characteristic impedance of the differential signal transmission pair cable is matched to that of the driver circuit and the receiver circuit, thereby enabling TEM waves of differential signals having GHz frequency band transmission mode to be maintained when the differential signals are transmitted.

An apparatus and method for sealing pipes or underground structures is provided. In one embodiment, the end of a pipe is sealed by the use of a pipe liner and a sealing member. The sealing member may be a hydrophilic material, a hydrophobic material, a compressible material, or a paste.

A device and method for sealing a first cylinder in a fixed position inside a second concentric cylinder. The inner cylinder has an annular depression in its wall at the point of sealant placement, which causes the wall of the inner cylinder to intrude inwardly. The depression is filled with a partially compressible fluid and is covered over by a malleable / ductile sleeve. The inner cylinder is placed within the outer cylinder with the covered annular depression positioned at the desired sealing point. A cylindrical displacement device is directed through the inside of the inner cylinder where it encounters the intrusion of the annular depression. The displacement device is forced past the annular intrusion and pushes the wall outward. The partially compressible fluid is forced to expand outward under the malleable / ductile cover in a manner that intrudes into the annular space between the inner cylinder and the outer cylinder and into contact with the outer cylinder. The partially compressible fluid has a residual energy sufficient to maintain the sealing element in contact with the outer cylinder.

A cable bypass assembly is disclosed for use in providing a high speed transmission line for connecting a board mounted connector of an electronic device to a chip on the device board.

The connector terminals are arranged in alignment with the cable signal conductors and shield extensions are provided so that shielding can be provided up to and over the termination between the cable signal conductors and the board connector terminal tails. Likewise, a similar termination structure is provided at the opposite end of the cable where a pair of terminals are supported by a second connector body and enclosed in a shield collar. The shield collar has an extension that engages the second end of the cable.

Conventional foamable cavity sealing articles are susceptible to sagging when expanded in a vertical orientation with the foaming material facing downwards, because of gravitational drag on the molten material during expansion. The problem is particularly pronounced in foaming materials formulated to have high expansion ratios and low melt viscosities. A solution to the problem is presented in the form of a cavity sealing article having a planar holder and a foamable sealer, the foamable sealer circumscribing the edge of the support member. This construction creates a gripping effect which prevents sagging of the sealing member during expansion.

The gasket includes a metal retainer member having generally planar first and second surfaces with at least one aperture formed therethrough which is configured for generally coaxial registration with a fluid passageway defined through the pipe flanges. At least one generally annular, flame resistant outer seal member is supported on the retainer member as disposed coaxially with the aperture thereof a spaced-apart, radially outward distance therefrom. The outer seal member has oppositely-disposed first and second outer radial sealing surfaces for abutting contact with a corresponding one of the interfaces surfaces, and is compressible axially between the interface surfaces for effecting a first fluid-tight seal about the fluid passageway. At least one generally annular, elastomeric inner seal member optionally is attached to the retainer member as disposed coaxially with the aperture thereof radially inwardly of the outer seal member. The inner seal member has oppositely-disposed first and second inner radial sealing surfaces for abutting contact with a corresponding one of the interfaces surfaces, and is compressible axially between the interface surfaces for effecting a second fluid-tight seal about the fluid passageway.

A gasket system for sealed interfaces utilizes a carrier ring having inner and outer compression stops to account for and control flange rotation effects in order to achieve a uniform and constant gasket seating stress across the sealing region. The inner compression stop provides a fixed fulcrum for flange rotation. The inner and outer compression stops have different heights, dependent upon the characteristic flange rotation, that allow the orientation of the sealing material to be angularly matched to the flange side profile and that allow the sealing material to be fully captured within the sealing region upon full compression, minimizing creep relaxation. A visual compression indicator on the circumference of the carrier ring permits assembly of the interface without the use of specialized or calibrated tools.

Explosion proof enclosures and explosion proof connectors and sensors are used to render a machine, intended to be operated in an explosive environment, explosion proof. An explosion proof connector includes an intermediate section having an input portion to receive a cable from a terminal external to an explosion proof enclosure and an output portion for passing the cable for connection to a terminal within an explosion proof enclosure. A sealing tube which extends between the input and output portions has a central opening for enabling a cable to be passed through. A sealant may be injected into the sealing tube to form an air tight connection between the cable and the inner walls of the sealing tube which inhibits a hazardous condition from passing through and around the sealing tube. An explosion proof sensor includes potting and encasing the sensor in its own explosion proof case.

A resilient gasket is disclosed for providing a seal between corrugated pipes having a plurality of concentric ribs on their outer surfaces, such as drain and sewer pipes to be buried in soil. The gasket comprises a base which is received around a first pipe over top of a rib adjacent an end of the first pipe, with an inner surface adapted to mate with a radially outer surface of the rib, and with legs adapted to extend along forward and rearwardly-sloped faces of the rib. The outer surface of the base is provided with sealing elements to engage the inner surface of the bell adjacent the end of a second pipe. The gasket also has a flap extending outwardly and forwardly from the forwardly extending leg. The flap and the forward leg form a V-shaped member. The flap engages the inner surface of the bell when the first pipe is inserted into the second pipe, and the gasket is rotated rearwardly relative to the rib. When the flap engages the inner surface of the bell, it prevents further rearward displacement of the gasket relative to the rib, thus preventing displacement of the gasket from the rib. The gasket also helps prevent gasket blowout during periods of unusually heavy water flow through the pipes.

The annular seal body defines one or more annular seal retainer grooves each having an annular soft metal sealing insert therein, with a portion thereof exposed for sealing engagement with the annular sealing surface. The spring loaded characteristic of the annular seal body applies constant force to maintain the soft metal seal insert in constantly energized sealing relation with the annular sealing surface and maintains effective sealing even when dimensional changes to the sealing surface occur due to temperature or pressure changes.
