Title: Tubular heat exchanger for a motor vehicle air conditioner
Inventor: SEYBOLD LOTHAR
IPC: F28D7/10
Filed: 2010-12-03
Abstract: A tubular heat exchanger for a motor vehicle air conditioner comprises an internal tube 12 through which a fluid flows and an outer tube 14 radially enclosing the internal tube thereby forming a space therebetween and through which a fluid flows. The internal tube has a plurality of stampings 16 on its surface and are spaced from one another and extend part way along the length of the tube. The stampings may be substantially rectangular with their longitudinal axis extending at an angle of 0 degrees to plus or minus 45 degrees. The stampings are arranged around the circumference of the internal tube, may be spaced in the longitudinal direction by 15mm to 30mm, their depth may be between 1mm and 3mm, the sum of their area may between 10 and 60 percent. The stampings may widen in a circumferential direction (fig 7), may be curved (fig 8) and may be, triangular, diamond (fig 9) trapezium or circular shaped. A gaseous refrigerant from an evaporator flows through the internal tube and a liquid refrigerant from the condenser flows through the space between the internal and outer tube.

Title: Protecting against theft of metal or other items from roofs and buildings
Inventor: THORNTON STEPHEN PATRICK
IPC: E04D13/14
Filed: 2011-07-01
Abstract: In one aspect, a securing arrangement is provided for fitting to a roof or wall of a building for securing a sheet of metal which is part of the building structure. At least one edge of the sheet is provided with the securing arrangement, which functions as an anti-theft arrangement, and comprises a wire reinforcement adhered over at least an edge of the sheet by an adhesive.

Title: Transmission having park pawl which is engaged after a predetermined delay
Inventor: CLARKE RICHARD
IPC: F16H63/34
Filed: 2011-09-05
Abstract: In response to driver selection of park, a vehicle transmission 13 is commanded to momentarily select and hold neutral before park, whilst a vehicle wheel brake is applied. Such an arrangement avoids trapping torque in the driveline, and thus can obviate pawl 'thump' when park is next disengaged. A control system comprises a rotary selector 16 is mounted on a centre console 17 and controls a condition of the transmission via an electric transmission actuator 14. A selector detector senses if a park or neutral condition has been selected and, if a brake controller has automatically commanded brake application, a park pawl is engaged after a pre-determined delay. The actuator 14 may also momentarily engage and hold the neutral condition of the transmission prior to engagement of the park pawl. The pre-determined delay may be settable and range from 1 second to 0.35 seconds.

Title: A connection formed under water between a wind turbine tower and a wind turbine foundation
Inventor: CHAMBERS PETER RONALD
IPC: F03D11/04
Filed: 2011-09-15
Abstract: A connection formed under water between a wind turbine tower and a wind turbine foundation. Mounted to the column 2 are brackets 6 which pass around posts 7 which are connected to a base member 3 comprising foundation 4. Enlarging members 8 are connected by swaged, crimped, pegged, wedged or other joints to the posts 7. For pre-loading, jacking members 10 or flanges 110 are operated to load the enlarging member 8 or flange 101 and spreader member 11 bearing on brackets 6 and column 2 with compression force and post 7 with same tension force to connect column 2 to base 3. A plinth extends from the base 3 into the column 2 forming a horizontal shear connection. The combined actions of tension in posts 7 and compression on base 3 and the shear plinth rigidly connect the tower to the foundation. Brackets 6 also increase the columns stiffness, which reduces horizontal deflections of tower.

Title: Image sensor
Inventor: DO THANH-TRUNG
IPC: H01L27/146
Filed: 2008-12-22
Abstract: The sensor includes a cascaded light guide that is located within an opening of the insulator and extends above the insulator such that a portion of the cascaded light guide has an air interface. The air interface improves the internal reflection of the cascaded light guide. The cascaded light guide may include a self-aligned color filter having air-gaps between adjacent color filters. The width of the gap t is 0.45/ngap (where ngap is the refractive index of the material within the gap).The footprint B of the light guide is within the footprint of the footprint A of the colour filter. Additionally, an anti-reflection stack is interposed between the substrate and the light guide to reduce backward reflection from the image sensor. Two pixels of having different color filters may have a difference in the thickness of an anti-reflection film within the anti-reflection stack. These characteristics of the light guide eliminate the need for a microlens.

Title: Electrical energy storage and generating unit with suspended weight
Inventor: BERGLAND WARWICK JOHN
IPC: F03G3/00
Filed: 2012-09-20
Abstract: An electrical energy storage and generating unit includes a large weight 1 suspended on a strong cable or chain 2 in a deep hole 3, eg a disused mine shaft, in the ground. The cable or chain passes over a pulley wheel 4 supÂ­ported over the top of the hole and is connected to and wound round a nearby winding drum 5 which can be engaged to and disengaged from an electric motor 6 and an electric generator 7 via gearboxes 8. Under low demand power is taken from an external primary source of electricÂ­ity to drive the motor to wind up the weight. During high demand on the primary source the weight descends under gravity, turning the generator to provide a secondary supply of power to supplement the primary source. The weight may be of streamlined shape to work in a flooded hole 3. In a modification (figs. 3,4), a combined motor-generator (12 is used instead of separate machines and the weight 1 is suspended using a block and tackle (10,11). Two winding drums 5 may be connected to one weight (fig.5).

Title: Polyelectrolyte dispersant filter aid
Inventor: DAY PAUL
IPC: C09K23/00
Filed: 2013-01-14
Abstract: A method of optimising the filter action of a filtering means in an aqueous containing liquid system in which the aqueous containing liquid system passes through an in-line mechanical filter means is characterised by introducing an additive formulation comprising a soluble polyelectrolyte dispersant into the aqueous containing liquid system. The additive formulation is not flushed from the system by draining the circuit and then replacing the system water, but remains in the system to effect removal by an in-line filter of the particulate debris upon which it has acted. Further, in remaining in the system, the additive formulation will disperse and suspend any solid particulate matter subsequently formed (e.g. by corrosion) or introduced into the system to allow effective capture by the filter. The additive formulation can be used in a central heating radiator.
