摘要： An electrical isolator includes a flexible non-electrically conductive membrane and an inelastic flexible dielectric member journaled in the membrane and extending from the first end of the membrane to the second end of the membrane. First and second couplings are mounted to the ends of the dielectric member. The ends of the membrane are mated in sealed engagement with the couplings so as to fluidically seal the ends of the membrane and the dielectric member within the membrane. The membrane is filled with a dielectric fluid so as to displace any air in the membrane and the dielectric member. The couplings are adapted to couple to objects at opposite ends of the electrical isolator.

摘要： The disclosure relates to a gripping apparatus, for use in connecting to a pipe wherein the pipe defines an inside radius, the apparatus having at least one discrete gripping device mounted on a body, wherein the body is a wedge cone; an outer surface on each of the at least one discrete gripping device, wherein the outer surface has a transition surface defined by a means for reducing any sharp transition point; a collective actuation-retraction mechanism connected to the wedge cone and to each of the at least one discrete gripping device; and a collective extension-retractable mechanism connected to each of at least one discrete gripping device. The disclosure further relates to an alternative exemplary embodiment wherein the gripping apparatus further includes a spring, wherein the spring pre-biases each of the at least one discrete gripping device beyond the inside radius of the pipe to instantly grip the inside radius.

摘要： A grounding clamp includes a safety lock-out which locks the operation of the clamp in the absence of a cooperating hot-stick. The lock-out employs a clutch which prevents the translation of the clamping members relative to one another until the clutch is disengaged. The cooperating hot-stick is required for the disengagement of the clutch.

摘要： A temporary support and conductor re-locator includes a mounting arm and corresponding mounting bracket on one end of the arm, the other end supporting a pivotally mounted insulator depending downwardly from a crank arm. The upper end of the crank arm is attached to an actuator which, upon actuation, pivots the crank arm and insulator about the end of the support arm so as to rotate up and out of the way an energized conductor contained in the wire holder at the bottom end of the insulator. The support arm is temporarily mounted to an existing transmission line tower or pole so as to extend outwardly substantially horizontally therefrom thereby cantilevering outwardly of the tower the end of the arm supporting the crank arm and insulator. Actuation of the actuator firstly elevates a lower portion of the crank arm then rotates the crank arm about the cantilevered end of the support arm.

摘要： A continuous processing system and method for the continuous processing of an electrical conductor cable having aluminum strands encasing a steel core directly from a puller or from a puller and reel, simultaneously or on-the-fly during substantially the entirety of a reconductoring or re-stringing of the cable, wherein such cables are used for power lines or for static wires. The system is adapted to cooperate with a pulling machine. The pulling machine may be formed integrally within the system or may be a conventional pulling machine which cooperates with the system. The processing system runs continuously, substantially without interruption, during the pull of all of the cable from the pull zone of the reconductoring or restringing.

摘要： A coupler pivot. A coupler (10) comprises at least a first gimbal (31; 32) defining a pivot that is secured to a mounting (41) for securing to a frame member of a vehicle, the pivot also being secured to a buffer column (39) part of which protrudes on an opposite side of the pivot to the mounting (41) such that the buffer column (39) is moveable relative to the mounting (41) with at least two degrees of freedom.The buffer column (39) defines a free (42) end that is remote from the mounting (41) and that is securable to a further member. The buffer column (39) also includes both a reversible buffer that attenuates buff and draft forces acting between the free end (42) and the mounting (41) and also a non-reversible buffer that attenuates buff forces acting between the free end (42) and the mounting (41) and attaining or exceeding a predetermined energy threshold, the reversible and non-reversible buffers overlapping over at least part of their lengths in the buffer column (39) which in turn overlaps at least one of the pivots.

摘要： A gripping apparatus for use in gripping a pipe, for holding forces, or restraining relative movement. The pipe defines an inside radius. The gripping apparatus has an outer surface where the outer surface defines a transition surface or a curve. In certain embodiments the transition surface or curve has a radius less than or equal to the inside radius of the pipe.

摘要： A buffer comprising a first, elongate buffer element that is moveably received within the interior of a second, elongate, hollow buffer element such that the first and second buffer elements overlap over part of their length, such that the buffer elements define a hollow interior of the buffer and such that at an end of the buffer at least the second buffer element is exposed for engagement with a respective, further member, the first and second buffer elements being moveable between a first, extended or intermediate configuration of the buffer and a second, compressed configuration, compression of the buffer more energetically than a threshold energy level causing the first buffer element to energize a non-recoverable energy absorbing member, forming part of the buffer or capsule, to cause deformation of one or more plastically deformable parts of the buffer, characterized in that the non-recoverable energy absorbing member lies between the ends of the buffer at least in the region energized by the first buffer element.

摘要： A downhole tool having a throughbore is disclosed for use in a tubular located in a wellbore. The downhole tool has a sealing element configured to seal an annulus between the downhole tool and an inner wall of the tubular; at least one flow path formed in the downhole tool, wherein the flow path is configured to allow fluids in the annulus to flow past the sealing element when the sealing element is in a sealed position; and at least one valve in fluid communication with the flow path and configured to allow the fluids to flow through the flow path in a first direction while preventing the fluids from flowing through the flow path in a second direction. A guard may be installed proximate anchor elements. The guard extends radially beyond an outer diameter of the anchor elements when the anchor elements are in a retracted position.
