Patent number: 11318500Abstract: The composition of articles can be identified using luminescent codes printed or coated onto the articles (or labels on the articles) by means of an ink which contains long persistence luminescent materials. Radiation is used to excite the luminescent materials and this is then extinguished before the article passes beneath a spectrometer. An infrared beam then strikes the article in order to stimulate emission from the long persistence luminescent materials, via a detrapping mechanism, and the spectrometer detects the emission in order to identify the article.Type: GrantFiled: April 19, 2018Date of Patent: May 3, 2022Inventors: Paul Gregory Harris, George Robert Fern, Jack Silver

Patent number: 10042096Abstract: A method for manufacturing a waveguide for a display apparatus comprising providing a planar optical waveguide part (20), depositing upon the optical waveguide part a fluid material (11) curable to form an optically transparent solid, impressing (30) upon the fluid material an impression defining an input diffraction grating region, an intermediate diffraction grating region and an output diffraction grating region wherein the fluid material of the intermediate diffraction grating region is continuous with the fluid material of at least the input diffraction grating region, curing (45) the impressed fluid material to solidify said impression. The physical location of the input diffraction grating is located wholly within the geographical area of the intermediate grating, and the grating vectors of the input diffraction grating and the intermediate diffraction grating are oriented in different respective directions.Type: GrantFiled: December 12, 2014Date of Patent: August 7, 2018Assignee: BAE SYSTEMS plcInventors: Michael David Simmonds, Anthony Robert Ferns

Patent number: 9874667Abstract: A waveguide for a display apparatus comprising a planar optical waveguide part (20) for guiding light to be displayed, an input diffraction grating (21) to diffract received light (7) along the optical waveguide part for guiding thereby, an intermediate diffraction grating (22) to receive diffracted light from the input diffraction grating and to expand the received light in a first dimension by diffraction (8), and an output diffraction grating (23) to receive the expanded light and to output the received expanded light (10) from the optical waveguide part by diffraction for display. The input diffraction grating is positioned so as to be located wholly within the geographical area of the intermediate grating, and the grating vectors of the input diffraction grating and the intermediate diffraction grating are oriented in different respective directions.Type: GrantFiled: December 12, 2014Date of Patent: January 23, 2018Assignee: BAE SYSTEMS plcInventors: Michael David Simmonds, Anthony Robert Ferns

Patent number: 8776892Abstract: A system for rotating an element inside a pressure containing housing. In some embodiments, the mechanism includes a pressure containing housing having an opening through a wall of the housing into an internal chamber in which, in use, the element to be rotated is located, a bushing located within the opening, and a worm gear rotatably mounted in the bushing. The worm gear is offset from the axial centre of the bushing such that rotation of the bushing moves the worm gear between an extended position, wherein the thread of the worm gear engages an element in the chamber, and a retracted position, wherein the thread is disengaged from the element in the chamber.Type: GrantFiled: January 18, 2013Date of Patent: July 15, 2014Assignee: Cameron International CorporationInventors: Robert Fern, Ted Thornburrow

Patent number: 8627895Abstract: A running tool for delivering a hanger into a wellcomprises a main body. In addition, the running tool comprise an attachment means for connecting a hanger to the main body. Further, the running tool comprises a sleeve having an external profile and being rotatably mounted around the main body. The sleeve has engagement means for releasably connecting the sleeve to a landing ring mounted via a thread on the hanger such that rotational movement of the sleeve causes rotational and thus axial movement of the landing shoulder on the hanger.Type: GrantFiled: October 13, 2008Date of Patent: January 14, 2014Assignee: Cameron International CorporationInventors: Robert Fern, Ted Thornburrow
