摘要:
A subsea system comprises a wellbore within a reservoir, equipment downstream of the wellbore, and a barrier connected to the equipment. The equipment is rated for a maximum pressure that is less than a maximum reservoir pressure and equal to or greater than the maximum reservoir pressure less external hydrostatic pressure experienced by the equipment. The barrier is rated for a maximum pressure that is equal to or greater than the maximum reservoir pressure.

This invention is directed to the pharmaceutical use of phenyl compounds, which are linked to an aryl moiety by various linkages, for inhibiting tumor necrosis factor. The invention is also directed to the compounds, their preparation and pharmaceutical compositions containing these compounds. Furthermore, this invention is directed to the pharmaceutical use of the compounds for inhibiting cyclic AMP phosphodiesterase.
摘要:
A modulator is disclosed for creating a pressure pulse in a fluid-filled well. The modulator comprises a tool body on which a plurality of extendable arms are mounted. The arms may be retracted into a stowed position substantially adjacent the tool body, or may be extended to meet the wall of the borehole. The arms are preferably resilient bowsprings that may be flexed outwards from the tool by means of an actuator pushing on at least one end of the springs. A flexible valve sleeve or bag is suspended between the arms and cooperates with a valve mounted adjacent the sleeve on the tool body. The valve sleeve creates a fluid-flow path through the valve, and in operation, the valve closes one end of the valve sleeve to create the pressure pulse. Sealing of the valve sleeve against the wall of the well is a result of the fluid pressure inflating the sleeve against the well wall. As a result, sealing takes place over an extended area of the bag and is dynamically responsive to changes in fluid flow or pressure.

Enamine derivatives of formula (1) are described: wherein R1 is a group Ar1 L2Ar2Alk- in which Ar1 is an aromatic or heteroaromatic group, L2 is a covalent bond or a linker atom or group, Ar2 is an arylene or heteroarylene group and Alk is a chain —CH2—CH(R)—, —CH═C(R)— or in which R is a carboxylic acid or a derivative or biostere thereof; R2 is a hydrogen atom or a C1-6alkyl group; Cy is a cycloaliphatic or heterocycloaliphatic ring in which X is a N atom or a C(Rw) group; Rx is a oxo, thioxo, or imino group; Rw and Rz is each a hydrogen atom or optional substituent; provided that Cy is not a cyclobutenedione group; and the salts, solvates, hydrates and N-oxides thereof. The compounds are able to inhibit the binding of integrins to their ligands and are of use in the prophylaxis and treatment of immune or inflammatory disorders, or disorders involving the inappropriate growth or migration of cells.

摘要:
A method of making a multitubular sheath comprising providing a porous multitubular fabric impregnated with thermoplastic or deformable polymer, continuously feeding the fabric onto an array of parallel metal rods, one tube to each rod, the rods having straight sizing portions, while holding the rods in a fixed position, the rods having substantially the same cross sectional area over the whole of their length, the fabric at least immediately prior to the sizing portions being substantially at ambient temperature, heating the fabric on the sizing portions so as to permit the fabric to conform to the rod, thereafter cooling the fabric on the rods to solidify or the deformable composite material to set to shape and the tubes to become self supporting, feeding the fabric off the ends of the rods and cutting it to the required length.
