Publication number: 20110065154Abstract: The present invention relates to a method for the deracemisation or chiral inversion of chiral amines by enzymatic treatment. The method employs a stereoselective enzymatic conversion and either a non-selective or partially selective chemical or enzymatic conversion, simultaneously or sequentially. The invention also provides a method for selecting a suitable enzyme, particularly a suitable amine oxidase, and for the generation of novel enzymes suitable for use in the deracemisation method.Type: ApplicationFiled: November 16, 2010Publication date: March 17, 2011Inventors: MARINA VICTOROVNA ALEXEEVA, ALEXIS ENRIGHT, MAHMOUD MAHMOUDIAN, NICHOLAS TURNER

Publication number: 20100158693Abstract: The present invention relates to a test blade for a blade-release test. The blade is arranged in use to be mounted on a hub for rotation, and to be released therefrom by the action of a controlled explosion. The blade is arranged to receive at least one explosive charge and at least one detonator for detonating the charge. The blade further comprises a cut-through portion extending completely through the blade from a front face to a rear face, the cut-through portion also extending part way along the blade in an axial direction between a leading edge and a trailing edge of the blade.Type: ApplicationFiled: November 11, 2009Publication date: June 24, 2010Applicant: ROLLS-ROYCE PLCInventors: JOANA VAZ VIEGAS, Jermey Nicholas Turner

Patent number: 7546804Abstract: An artillery charge includes a generally cylindrical body with a hollow core; propellant disposed in the body and first energetic material disposed in the hollow core; and a seal disposed over one end of the hollow core, the seal including second energetic material disposed therein. A laser igniter ignites the second energetic material in the seal, thereby providing more reliable ignition of the first energetic material and the propellant. The artillery charge reliably ignites using a lower powered laser than known charges.Type: GrantFiled: October 10, 2006Date of Patent: June 16, 2009Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Anthony E.

Patent number: 7186035Abstract: An optical fibre connector includes a connector having a receptacle or socket with a recessed optical fibre ferrule assembly for aligning an optical fibre within the connector. An optical socket has recessed therein a sleeve for receiving and bringing into optical alignment an optical fibre ferrule assembly at an internal end of the socket with a similar optical fibre ferrule assembly of an optical plug connected to the optical socket. The optical connector has a housing with at least two portions that are removably secured to one another. A method of cleaning such a recessed assembley includes removing at least one of said portions from the remainder of the housing. Contamination is then cleaned from the optical fibre ferrule assembly. Then, the the removed portion(s) are reassembled with the remainder of the housing.Type: GrantFiled: May 12, 2004Date of Patent: March 6, 2007Assignee: Avago Technologies Fiber IP (Singapore) Pte.
