Title: Evacuated solar panel enclosure
Inventor: ALBINSON JOHN
IPC: F24S10/70
Filed: 2006-06-20
Abstract: An evacuated enclosure is provided to house a solar radiation panel 4 in which the front of the enclosure is formed by a curved and transparent solar radiation window 1 supported along its edge by a side rail 3 which is held in place by the force arising in a rear membrane 2 forming the back of the enclosure. Preferably, the solar radiation window is curved such that a compressive force resulting from the external air pressure acts substantially within the plane of the window and where this compressive force is opposed by a tension force resulting from the external air pressure acting on the rear membrane. Preferably, the tension force in the rear membrane is arranged to be of a larger magnitude than the compressive force in the solar radiation window, by virtue of the rear membrane having a flatter curvature than the solar radiation window. The net difference between the forces acting in the solar radiation window and the rear membrane may be transferred via the side rail into a network of rear struts 8 that may also provide a means of external mounting. The solar radiation window and rear membrane may either be curved in one axis with the enclosure completed by end sealing plates 11, or they may be curved in two axes to form a circular domed enclosure.

Title: Increasing reception quality in a wireless communication syst em incorporating relays
Inventor: SIMOENS SEBASTIEN
IPC: H04B7/15
Filed: 2006-06-28
Abstract: A wireless relay unit (105) comprises a receive front end (201, 203) generating time domain signal samples for a signal received from a source communication unit (101). A noise processor (205) generates a noise indication for the samples and a quantisation level processor (207) determines quantisation levels such that a noise contribution resulting from quantising relative to the noise indication meets a criterion. A quantisation processor (209) generates quantised signal samples by quantising the samples using the quantisation levels, which are then transmitted (211) to a mobile user unit (103). A receive front end (301, 303, 305, 309) of the mobile user unit (103) generates receive signal samples for the signal from the source communication unit (101) and a MIMO receive processor (311) performs a Multiple In Multiple Out, MIMO, reception of the signal using these samples and the quantised signal samples from the relay unit (105). By combining signals directly from a source unit with those passed through a relay unit, reception quality is improved.

Abstract: A parasol device 100 comprises a hollow pole 110 in which a reciprocally movable support pole 120 is mounted, at one end of which are mounted a number of spokes 130 designed to fix and carry parasol sheeting. Attached to each spoke is a holding rod 131 fixed to the hollow pole at its first end in a bearing 111 and with its other end supporting the relevant spoke at its centre.

Title: Communicating with a perforating gun across a barrier using high intensity signals
Inventor: HENDERSON STEVEN W
IPC: E21B43/1185
Filed: 2007-09-20
Abstract: A method of communicating across a communication barrier in a wellbore involves generating a first command-encoded signal with sufficient energy to cause a second command-encoded signal to emerge from the communication barrier. The second command-encoded signal is responded to and activates a downhole tool. The signal can be produced by a fluid hammer or a ballistic based impulse generator. Also claimed are methods of communicating in a well acoustic energy having most of its spectral energy at a frequency greater than 300 Hertz and communicating a ballistic wave in a well from a first point to a second point without propagating the ballistic wave along a detonation cord, where the first and second points are separated by one foot. The methods are said to be useful in communicating with and activating a perforating gun.

Title: Extracting energy from waves in the form of compressed air
Inventor: GARVEY SEAMUS DOMINIC
IPC: E02B9/08
Filed: 2008-12-11
Abstract: This invention relates to a Wave Energy Converter (WEC) system intended for compressing air. The system comprises a number of air compressor units (9 figure 2) arrayed in a flotilla such that although each individual device compresses by only a small ratio, the combined effect is to raise the air pressure from atmospheric conditions by a factor of several tens. The devices are arranged as a series of banks 2 & 4 interleaved with intermediate air reservoirs 1, 3, 5 & 6 between the banks and with each bank comprising a parallel combination of individual devices. The individual devices each use buoyancy to cause movement of one part relative to another part which includes a "heave-plate" or "drag-anchor" (22 figure 2) to resist vertical motion. A linear magnetic coupling (20 & 21 figure 2) may be used to transmit motion across the wall of a sealed chamber (9 figure 2) and by using a deformable divider within that sealed chamber, air compression is achieved without the use of any moving seal. Options are described using either a bellows-structure or a rolling-membrane (10 figure 2) as the deformable divider.

IPC: F16H48/42
Filed: 2008-12-18
Abstract: A method of machining a flange 20 on a differential pinion shaft (16, fig 1) having a input pinion 10 formed as a hypoid gear (14) and mounted for rotation in bearings (18), the method comprises rotating the input pinion 10 about its rotary axis Y, and forming an initial cylindrical surface of a recess 26 using a stationary cutting tool 30; determining a coordinate position of a central axis of the initial cylindrical surface; and consequently of a rotary axis Y of the input pinion 10; and holding the input pinion 10 stationary, and forming a finished cylindrical surface using a rotating cutting tool (36) which rotates about the central axis Y determined previously. As a result of this procedure, the finished cylindrical surface of the recess 26 is accurately generated and centred on the rotary axis Y. A dummy ring gear 28 is rotated about an axis X and in turn drives the input pinion 10 and flange 20. Apparatus for carrying out the method includes a motor (56) which rotates the dummy ring gear 28 and is mounted to a support structure. The dummy ring gear 28 may be locked against rotation by an internal brake of the motor (56) or it may be locked by a separate device. A contact sensor (34) establishes several coordinates around recess 26 and a processor calculates a position of the axis Y which is used as the rotating axis of the rotating cutting tool (36).

Title: Rotating machine with sealing arrangement
Inventor: PURDY MATTHEW J
IPC: F01D25/18
Filed: 2009-04-02
Abstract: A rotating machine, such as an axial power turbine or a turbocharger, has a housing (2) with a bearing cavity and a chamber separated by a first wall. A shaft (7) is rotatable about an axis in the bearing cavity, extends through an opening in the first wall and is mounted for rotation on a bearing assembly (10) provided in the bearing cavity. An oil sealing arrangement 31 including an oil diffuser device 37 is arranged on the shaft for displacing oil away from the shaft as it rotates. This restricts the flow of oil to the opening. The oil diffuser device defines a diffuser passage 39 between the bearing assembly and the first wall, the passage extending outwardly of the axis. The passage has a first portion that extends with a dominant radial component and a second portion that extends in a direction having a greater axial component than the first portion. The oil diffuser reduces the oil flow velocity along the passage such that gravitational and surface tension forces dominate and the oil pours from an outlet of the passage.
