Abstract: A fitting for joining pipe elements together includes housing portions held preassembled in spaced apart relation to permit pipe elements to be inserted without disassembly of the fitting. Elbow and tee fittings include sealing elements which support the housing portions in spaced relation. Angled surfaces on each housing portion interact with one another to rotate the housing portions in opposite directions to form a rigid joint between the fitting and the pipe elements.

Abstract: A coupling for joining pipe elements in end to end relationship is disclosed. The coupling includes a sealing member having an inner diameter and an outer surface. A plurality of segments are supported on the sealing member's outer surface. Each segment has a pair of arcuate surfaces positioned in space relation on either side of the sealing member. A compression band surrounds the outer perimeter of the segments, the segments being captured between the band and the sealing member. The pipe elements are inserted into the inner diameter between the segments. A tensioning member is mounted on the band. Tightening of the tensioning member causes the compression band to force the segments radially inwardly into engagement with outer surfaces of the pipe elements.

Abstract: A mechanical pipe coupling formed of segments attached end to end surrounding a central space is used to connect pipe elements having a raised circumferential shoulder in end to end relationship. The segments have arcuate surfaces and arcuate landings which subtend an angle less than 180° and which have a radius of curvature greater than the radius of curvature of outer surfaces of the pipe elements on the raised circumferential shoulder. The segments are maintained in spaced relation allowing the pipe elements to be inserted into the central space without disassembling the pipe coupling. Connection members attaching the segments to one another are tightened to engage the arcuate surfaces or the arcuate landings with outer surfaces of the pipe elements to effect the connection.

Abstract: A processing circuit 4 is responsive to at least one conditional instruction to perform a conditional operation in dependence on a current value of a subset of at least one condition flag 22. A trace circuit 6 is provided for generating trace data elements indicative of operations performed by the processing circuit 4. When the processing circuit 4 processes at least one selected instruction, then the trace circuit 6 generates a trace data element including a traced condition value indicating at least the subset of condition flags 22 required to determine the outcome of the conditional instruction. A corresponding diagnostic apparatus 12 uses the traced condition value to determine a processing outcome of the at least one conditional instruction.

Abstract: A trace unit, diagnostic apparatus and data processing apparatus are provided for tracing of conditional instructions. The data processing apparatus generates instruction observed indicators indicating execution of conditional instructions and result output indicators indicating output by the data processing apparatus of results of executing respective conditional instructions. The instruction observed indicators and result output indicators are received by a trace unit that is configured to output conditional instruction trace data items and independently output conditional result trace data items enabling separate trace analysis of conditional instructions and corresponding conditional results by a diagnostic apparatus. The instruction observed indicator is received at the trace unit in a first processing cycle of the data processing apparatus whilst result output indicator is received at in a second different processing cycle.

The dietary supplement is particularly, but not exclusively, suitable for animals.

Abstract: A method of manufacturing an installation-ready pipe coupling is disclosed. The method includes providing pipe coupling segments each having an initial radius of curvature and an initial subtended angle. The segments are each deformed so as to take a permanent set and have a final radius of curvature greater than the initial radius of curvature and a final subtended angle smaller than the initial subtended angle. The deformed segments are assembled in end-to-end relation using adjustably tightenable fasteners to form a coupling. The deformed segments are maintained in spaced relation so that pipe elements can be inserted between them without disassembly of the coupling.

Abstract: A method for drilling a wellbore comprises extending a rotatable drill string in the wellbore, where the drill string has a bottom hole assembly coupled to a bottom end thereof. A lower section of the bottom hole assembly comprising a steering apparatus is coupled to an upper section of the bottom hole assembly with a controllably adjustable clutch. A steering apparatus toolface angle is detected. The clutch is controllably adjusted to maintain the steering apparatus toolface angle within a predetermined range about a target steering apparatus toolface angle while rotating the upper section with the drill string.

Abstract: A preassembled mechanical pipe coupling having spacers is disclosed. The coupling has a plurality of interconnectable segments that straddle the ends of pipe elements to be joined. The segments have arcuate surfaces that engage outer surfaces of the pipe elements. Spacers, positioned between the segments, maintain them in spaced apart relation sufficient to allow the pipe elements to be inserted between the segments. The segments have adjustably tightenable connection members for connecting the segments and drawing them to one another. When the connection members are tightened and the effect of the spacers is overcome, the arcuate surfaces are brought into engagement with the outer surfaces of the pipe elements.

Abstract: A mechanical pipe coupling having segments joined end to end by connection members has arcuate surfaces and flanges in spaced relation to the arcuate surfaces on each segment. The coupling is positionable between a first pipe element having a cylindrical outer surface and a second pipe element having an end flange to couple the pipe elements to one another. The arcuate surfaces engage the outer surface of the first pipe element; the flanges engage the end flange on the second pipe element. One or more spacers support the coupling segments in spaced relation to one another to permit insertion of the first pipe element between the segments. The spacers are deformable upon tightening of the connection members to permit the arcuate surfaces to engage the pipe element and the flanges to align with the end flange.

Abstract: A preassembled mechanical pipe coupling for joining pipe elements in end-to-end relationship is disclosed. The coupling is formed from a plurality of interconnectable segments that are initially maintained in spaced apart relation. The segments have arcuate surfaces that project inwardly. Connection members in the form of lugs and fasteners are mounted on the segments. The connection members are adjustably tightenable for drawing the coupling segments together and forcing the arcuate surfaces into engagement with the outer surfaces of the pipe elements. Notches are formed at ends of the arcuate surfaces to provide clearance allowing the pipe elements to be inserted between the segments when they are in the pre-assembled, spaced apart configuration.
