IPC: F24D1/08
Filed: 2006-10-12
Abstract: A closed cycle heat transfer device has an evaporator/boiler 10, a condenser 13, and an expansion device 16, arranged in a fluid circuit. The fluid circuit includes a first duct 12 transporting heated fluid from the evaporator/boiler to the condenser, and a second duct 15 returning condensate to the evaporator/boiler. The second duct also includes a connection to the expansion device, to permit compensation for expansion of the fluid vapour phase. The expansion device may include a flexible membrane (20 fig 3), and the device may be a vessel (17 fig 3) divided into two enclosed separate chambers 18,19. The vessel may also include a valve (21 fig 3) which permits adjustment of pressure within the chambers, and the valve may permit a gas to be introduced. The gas may act against one side of the flexible membrane, the opposite side of which is in communication with the working fluid in the liquid phase. The condenser may be an indirect heat exchanger which is used to heat a working fluid in an Organic Rankine Cycle. The closed cycle heat transfer device can also be a heat pipe.

Title: Detecting vibration in a gas turbine engine
Inventor: MERWE GERT JOHANNES VAN DER
IPC: F04D29/00
Filed: 2007-04-13
Abstract: A monitoring system 100 for a jet engine includes at least one sensor configured 102 to transmit a signal indicative of a vibration level of a rotor assembly within the gas turbine engine and an engine monitoring unit (EMU) comprising processor means 104 coupled to the at least one sensor for receiving the signal transmitted therefrom. The EMU is configured to detect the vibration level of the rotor assembly based on the signal transmitted from the at least one sensor and generate an output 106 if the detected vibration level exceeds a threshold level for a predetermined time period. In this way it facilitates identification of a gas turbine engine impulse event. The at least one sensor may be an accelerometer. Specifically, vibrations in the fan assembly and compressor may be monitored. The speed of rotor assembly components may also be measured. The system may be used to detect unusual operating conditions in use rather than waiting for a scheduled inspection.

Title: Electrode configuration of electrolysers to protect catalyst from oxidation.
Inventor: ROY AMITAVA
IPC: C25B9/19
Filed: 2009-04-06
Abstract: An electrode configuration for a water electrolyser wherein the anode and cathode are coated with a protective material which protects the active catalysts when the apparatus is not in use or is in standby mode. The anode is coated with a material defined as an "oxygen storage material" such that the coating is preferentially oxidised over the anodic active catalyst. The material may be cerium dioxide (ceria) or zirconium. The cathode is coated with a material defined as a "hydrogen storage material" which supplies or releases hydrogen when the electrolyses is not in use. When the electrolyser is not in use a reduction load is connected between the anode and cathode which converts metal oxides into pure metal by consuming oxygen from the electrolyser cell and hydrogen released by the hydrogen storage material. The coatings will increase the life time and durability of electrodes.
Patent GB-2459757-A (GB)
Title: Video signal comprising two camera viewpoints
Inventor: MUZAFFAR SAJ
IPC: H04N7/24
Filed: 2009-04-15
Abstract: A video signal comprises multiplexed sequences of synchronous frames taken from different camera angles that enable a viewer to play back and switch between camera angles. Frames 1-9 constitute frames from a first (camera angle one) video sequence and frames 10-18 from a second (camera angle two) video sequence. The viewer starts to play the encoded multiple angle video file and the sequence for camera angle one is played. At frame 3 the viewer presses a key to change the camera angle. The player counts the number of frames lapsed and then adds the number of frames between the two camera angle video sequences, (in this case nine), so the player jumps to frame 12 and starts to play camera angle two from frame 12 onwards. The signal may be used with a mobile device using cell, wireless or internet connections. Independent claims for methods and apparatus for recording, transmitting, receiving and replaying are included.

Title: Production and Distribution of Natural Gas
Inventor: ALFORD ADRIAN GRAHAM
IPC: F25J1/02
Filed: 2009-05-08
Abstract: Natural gas is liquefied at a production site by compression 10, cooling in an after-cooler 12, after first mixing with it a refrigerant. The condensed refrigerant is separated from the compressed gas in a separator 14, flashed through an expansion valve 16 and used to cool the natural gas further. To liquefy the now compressed natural gas, it is passed through heat exchangers 18, 22, where it is cooled by the refrigerant, such as liquid nitrogen, or a cooled refrigerant gas of a reverse Brayton cycle refrigeration circuit. At a market site (Fig 2), the liquid natural gas can be used to produce liquid nitrogen which is returned to the production site using the same insulated containers as used for transporting the liquid natural gas from the production site to the market site. The liquid nitrogen is produced at the market site by using natural gas to fuel an engine (60 Fig 2) that powers a compressor (68, 70, Fig 2)acting to compress the exhaust gases of the engine before they are cooled by the liquid natural gas. Water and carbon dioxide condense at different stages of the cooling process and are removed.

Title: Shape memory alloy actuation apparatus
Inventor: TOPLISS RICHARD
IPC: G02B7/00
Filed: 2008-02-11
Abstract: A miniature camera lens actuation apparatus provides an auto-macro function in which a camera lens element has two focus positions. In one type of apparatus, a shape memory alloy actuator arranged to drive movement of the camera lens element relative to a support structure against an end-stop arranged to limit the movement. The shape memory alloy actuator is connected to one of the movable element and the support structure by a compliant connector. This limits the stresses on the shape memory alloy actuator and therefore increases its lifetime. In another type of apparatus, the suspension system supporting the movable element on the support structure provides the movable element with two stable positions along the movement direction.

Title: Improvements in or relating to hydraulic control devices
IPC: F15B11/028
Filed: 1944-05-24
Abstract: 586,641. Fluid-pressure servomotor-control systems. MARTIN, E. May 24, 1944, No. 10084. [Class 135] A variable-pitch propeller is controlled by a hydraulic servomotor wherein some of the liquid supplied to the system at a low pressure is passed through a booster pump and on to a pressure chamber in which the pressure is limited by a relief valve, the latter being loaded by a spring in conjunction with the pressure of the low pressure liquid, and means is provided for alternatively connecting one side of the pitch-changing motor to the pressure-boosted liquid and the other side to the low pressure liquid. Oil is drawn from a reservoir 32, Fig. 1, by the engine lubricating pump 30 and is supplied to a booster pump 44, to a relief valve 80 where it acts to assist the loading spring 82, Fig. 2, and through a passage 53 to a part in a control valve 56 which is actuated by an engine speed governor 58. The high pressure oil from the booster pump passes to a chamber 46 and to a second port in control valve 56. When the pressure in chamber 46 is excessive, it acts on a piston 88 and pushes the latter back against its loading means to open a port 90 and vent the excess pressure back to the inlet of the booster pump. Valve 56 controls the connection of the high and low pressure lines through conduits 62, 65, oil collector ring 64, passages 38 and 40, 66 to alternative sides of a piston motor 24 situated in the hub of the propeller drive shaft. The resultant longitudinal movement of the latter is translated as described in Specification 505,077 into a rotary movement which, through bevel gears 22, 20, alters the pitch of the propeller 18. Specification 557,316 also is referred to.
