Patent number: 7932322Abstract: The invention relates to viscosifiers, especially terminated polymers that have functional terminal groups, said polymers being pre-extended by polyamines, polymercaptans, (poly)aminoalcohols, (poly)mercaptoalcohols or (poly)aminomercaptans and being reacted to give polymers that are terminated by other functional groups. The viscosifiers have a low content in educts or educt descendants that deteriorate the properties of compositions. They are also charaterized in that the formation of high-molecular addition products is considerably reduced or even excluded so that products obtained have low viscosity and good storage stability. The epoxy-terminated polymer of formula (I) is especially preferred.Type: GrantFiled: December 21, 2007Date of Patent: April 26, 2011Assignee: Sika Technology AGInventors: Andreas Kramer, Jan Olaf Schulenburg, Jürgen Finter, Norman Blank

Publication number: 20100155073Abstract: Systems and methods for improved hydraulic control systems for actuation of subsea equipment in deep water are disclosed. The hydraulic control system relies on smaller fluid flow associated with a hydraulic pressure pulse to actuate the small volume actuation control valve. In one embodiment, the system includes small diameter control umbilical hoses and pilot-operated valves with low actuation volumes. Particularly, a hydraulic control system for reducing the signal time to a subsea blowout preventer in water depth up to and greater than about 5000 feet. Some embodiments comprise a valve arrangement which hydraulically actuate one side of a hydraulic control function, while simultaneously evacuating the opposing circuit both at the seabed and at the surface. Some embodiments comprise an umbilical hose located proximate the center of an umbilical bundle. Preferably, the umbilical hose has a plurality of layers of reinforcing fibers which increase with the diameter of the reinforcement layer.Type: ApplicationFiled: September 4, 2009Publication date: June 24, 2010Applicant: DIAMOND OFFSHORE DRILLING, INC.Inventors: Robert Norman Blank, John Stephen Hiltpold, Tri Canh Le, Brian Frank Matteucci, Patrick D.M.
