Abstract: A support clamp for clamping different sized lubricator or oilfield tubulars to allow for laying down lubricator tubular assemblies during rig up and rig down operations.

Abstract: An animal pregnancy test which includes detecting a hormone level in a bodily extract. The bodily extract is tested for a threshold level of the hormone, specifically oestrogen. The test includes a test substance and a material capable of facilitating movement of bodily extract within it. The test substance includes a substance capable of reacting with oestrone sulphate and an indicator dye which is attached to the surface of the substance capable of reacting with oestrone sulphate. The threshold level of the test substance is calibrated to suit specific species and to indicate the desired litter size of that species so that if the detected level of oesterone sulphate exceeds a predetermined threshold level for that species, then there is a high probability of the actual litter size exceeding the calibrated litter size. The apparatus for detecting pregnancy in animals consists of a testing substance, a control test, a sample extractor, and a sample container.

Abstract: An optical fiber cable has a kingwire (10) provided with inner and outer extruded layers (12, 18) of a thermoplastic elastomer. A plurality of optical fibers (14) are disposed on the outer surface (16) of the inner layer (12) and are embedded in the outer layer (18). The cable is constructed by extruding a thermoplastic elastomer around a kingwire, setting the elastomer layer, laying a plurality of optical fibers along the set elastomer layer and extruding a further layer of thermoplastic elastomer over the fibers.
