Inventor: FLEMING ANGUS
IPC: F03B13/26
Filed: 2011-10-20
Abstract: A system for attaching a rotor blade, e.g. a marine turbine blade to a turbine shaft, comprises a hub with a blade engagement portion 108 extending from the hub for engagement with a root portion 102 of a rotor blade. The engagement portion 108 has an alignment aperture (114, figure 3) and an alignment device 120 received within the alignment aperture. The alignment device 120 comprises a housing 130 and a liner 132 within the housing 130 defining an alignment space 141 between the housing 130 and the liner 132.

Title: Pressure Testing Subsea Modules, Piping or Components
Inventor: KAJANDER THOMAS
IPC: G01M3/00
Filed: 2011-11-18
Abstract: A method of pressure testing a module containing fluid, the method comprising: sealing the module; applying heat to the module to increase the temperature and thus the pressure of the fluid from a working pressure to a test pressure; and conducting a test, and subsequently cooling the module or allowing the module to cool until the fluid pressure returns substantially to the working pressure. Application of heat may be by fluid recirculation by pump 6 around the piping in the isolated test section 3, and the loop 7. Electric motor 9 drives the pump 6 and this motor heats up in use and imparts heat to the fluid within the isolated section 3 and the pressure of the fluid increases as a result. Figure 2 shows an alternative method of heating which comprises using a heat exchanger to increase the temperature in the isolated section 3.

Title: 3D prescription spectacles
Inventor: BOFFEY JOHN ROBERT
IPC: G02B30/25
Filed: 2011-12-07
Abstract: A 3D lens blank for prescription 3D spectacles, comprising a thermo-formed dished 3D laminate blank fixed to a curved lens blank by adhesive, with contacting surfaces of the same profile. The front and back faces of the lens blank may have identical curvature and made of CR39 grade optically clear plastic. The 3D blank may be formed from 3D polarised film and tri-acetate cellulose, and adhered to a convex surface of the lens blank. Both lens blanks may be circular and of the same diameter, or the 3D blank may be of a lesser diameter than the Rx blank. The plano lens blank may have a 4 base curve. The manufactured blanks may be between 0.25 and 6 diopters. The 3D lens blank is machined on the non-laminated side of the lens blank and around its periphery, adhered by applying pressure between the inner and outer faces of the composite blank, and cured using heat. In order to prevent de-lamination during manufacture, the 3D laminate is broken in a direction perpendicular to the plane to form the shape of the spectacle lens, and edge machined to size. Machined blanks are inserted into frames to produce 3D prescription glasses.

Title: Near-field communication system in which power transfer is interleaved in time with data transfer
Inventor: MCFARTHING ANTONY LAWRENCE
IPC: G06K19/07
Filed: 2013-08-20
Abstract: The present invention is concerned with power transfer between a Near-Field Communication (NFC) interrogator and a passive NFC tag. The power is transferred in a first time period 602 and data communications take place in a second time period 600. This allows data to be transmitted at a high data rate using phase shift keying (PSK), frequency shift keying (FSK) or quadrature amplitude modulation (QAM). Preferably, power transmission periods alternate with communication periods in time. The interrogator preferably uses a higher Q-factor antenna for power transmission than for data transmission. This may be achieved by periodically switching between different antennas or by periodically adjusting an impedance of the antenna system.
