Patent number: 8107152Abstract: An electrically tunable Lyot type filter is a Lyot that include one or more filter elements. Each filter element may have a planar, solid crystal comprised of a material that exhibits birefringence and is electro-optically active. Transparent electrodes may be coated on each face of the crystal. An input linear light polarizer may be located on one side of the crystal and oriented at 45 degrees to the optical axis of the birefringent crystal. An output linear light polarizer may be located on the other side of the crystal and oriented at ?45 degrees with respect to the optical axis of the birefringent crystal. When an electric voltage is applied between the electrodes, the retardation of the crystal changes and so does the spectral transmission of the optical filter.Type: GrantFiled: August 29, 2008Date of Patent: January 31, 2012Assignee: Nova PhotonicsInventor: Fred M.

Patent number: 8101693Abstract: This invention relates to the polymerization of ethylene polymers using a continuously stirred tank reactor (CSTR) that is connected in series to a tubular reactor. The tubular reactor receives a polymer solution from the CSTR. Further polymerization in the tubular reactor improves production efficiencies, particularly with respect to lowering the amount of energy required to recover the polymer and residual comonomer from the solution. The use of tempered i.e. (heated) ethylene in the tubular reactor has been discovered to mitigate gel problems and lower/reduce levels of hexane extractables.Type: GrantFiled: December 6, 2010Date of Patent: January 24, 2012Assignee: NOVA Chemicals (International) S.A.Inventors: Lauwrence Martin Jozef Van Asseldonk, Stephen John Brown
