Patent number: 8956548Abstract: The present, invention relates to liquid crystal compositions having a smectic A structure for use in an optical device in which the composition is sandwiched between a pair of electrodes (12-15). In essence the composition includes a siloxane oligomer (component (a)) which may be seen to construct a layered SmA system of particular spacing and “strength”. Within this structure a low molar mass nematic mesogen (component (c)) is provided that may be considered to be that of a “plasticiser” which moderates the layer “strength”, while simultaneously providing tuneability to the properties of the composition, e.g. its refractive index or dielectric anisotropy. The addition of a side chain liquid crystal polysiloxane (component (d)) allows such systems to be further moderated since they can be considered as binding together the la>¾rs, both within a given layer and between layers.Type: GrantFiled: March 15, 2011Date of Patent: February 17, 2015Assignees: Dow Corning Corporation, Cambridge Enterprise LimitedInventors: Terry Victor Clapp, William Alden Crossland, Anthony Bernard Davey, Martin Grasmann, Jonathan Paul Hannington, Russell Keith King, Mikhael Pivnenko, Steven Robson, Huan Xu

Patent number: 8889037Abstract: A method can include combusting an expanded turbine exhaust and a first fuel within a first reformer to produce a first exhaust. A hydrocarbon can be reformed in the first reformer to produce a reformed hydrocarbon and heat can be transferred from the first exhaust to a first medium. A refrigeration unit can be powered with thermal energy from the heated first medium and can cool a second medium. Heat can be transferred from one or more oxidants to the cooled second medium to produce cooled first and second oxidants. The cooled first oxidant and a second fuel can be introduced to a gas turbine unit to produce the expanded turbine exhaust and mechanical power. The cooled second oxidant can be compressed in a compressor powered with the mechanical power and the compressed second oxidant and the reformed hydrocarbon can be introduced to a second reformer to produce a syngas.Type: GrantFiled: February 1, 2011Date of Patent: November 18, 2014Assignee: Kellogg Brown & Root LLCInventors: Shashi Singh, Keith King
