The ridges have a larger bottom width than top width. The centre lines of the die ridges are substantially parallel at a distance, and the die, when unengaged, is radially movable between abutment of the die ridges to the die holder and abutment of the die to at least one stop member of the die holder.

A machine for welding saddle connectors by polywelding, during pipe laying, includes a base which extends in a first direction, a clamp which can move along the base in the first direction, a bracket mounting means for detachably coupling the machine to a pipe arranged transversely to the first direction, and a means for detachably coupling the base to the bracket mounting means.

A clamp arrangement for a cylindrical object including a clamp member adapted to receive an end of a cylindrical object, the clamp member having an inner clamping surface and an internal thread; a wedge having an inner surface adapted to be in contact with a side surface of the cylindrical object, and an outer surface adapted to be in contact with the inner clamping surface; and a circular tightening member having an external thread compatible with the internal thread of the clamp member, and an end surface adapted to be in contact with an end surface of the wedge. The clamp member, the wedge, and the circular tightening member are adapted to co-operate with each other for fastening the cylindrical object to the clamp member.

The clamp assembly includes a mount ring with a first portion including a first passage extending along a first longitudinal axis, a second portion including extending along a second longitudinal axis spaced transversely apart from the first longitudinal passage, and third portion including a third passage extending along a transverse axis between the first and second longitudinal axes, and a clamp movably carried in the third passage of the third portion of the mount ring, and a cam engageable with the clamp to move the clamp toward the first portion of the mount ring. Also disclosed are related clamps and mounting rings.

An adjustment device to align a plurality of tube sections is disclosed. The device comprises at least two sheave sections fixedly attached to a threaded shaft via a socket assembly, wherein the threaded shaft substantially extends in a longitudinal direction to meet a base plate. An adjusting means positioned at an upper end of the threaded shaft is configured to radially align the base plate along the confronting ends of the tube sections via a plurality of wire rope wound around the sheave section. The adjusting means comprises a socket and a ratchet to adjust the device to align the tube sections and the plurality of wire rope (conform a basket hitch) the confronting ends of the tube sections for alignment in a limited room for space.

Provided is an apparatus for preparing wire rope having a stand; a first cross-member; a second cross-member; a first clamp arm; a second clamp arm; a first clamp; a second clamp; an adjustment wheel; an adjustment screw; and an adjustment gear; wherein the second cross-member is at least partially contained within the first cross-member; wherein the first clamp is disposed at the distal end of the first clamp arm, the second clamp is disposed at the distal end of the second clamp arm, and wherein the first and second clamp arm are spaced from each other; and wherein the distance between the first and second clamp arm is adjustable. Also provided is a method of use for the same.

An apparatus for aligning sections of pipe includes a first clamp member and a second clamp member coupled with the first clamp member. The first and second clamp members each include a first clamp jaw and a second clamp jaw longitudinally spaced from the first clamp jaw. Each one of a first plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the first clamp member, and each one of a second plurality of turnbuckle assemblies is coupled with each one of the first and second clamp jaws of the second clamp member. An assembly made from a kit of components is also disclosed. The kit includes an apparatus for aligning sections of pipe, and a plurality of shoe inserts. The assembly includes the apparatus and at least two of the shoe inserts coupled with the apparatus.

An apparatus for making a flow determination with respect to a flow through a fluid conduit such as a domestic water pipe, the fluid conduit comprising a wall having an inner surface surrounding a flow space through which the fluid flows and an outer surface, the apparatus comprising: a first temperature sensor arranged to be mounted on the outer surface of the fluid conduit and arranged to generate a first temperature signal indicative of a first temperature being the temperature of the outer surface; a second temperature sensor arranged to be positioned spaced apart from the first temperature sensor and to generate a second temperature signal indicative of a second temperature being the ambient temperature outside of the fluid conduit; and a processor having inputs for the first and second temperature signals; in which the processor has an output for the flow determination and is arranged to make the flow determination by determining a measure of the convergence of the first and second temperatures over time.
