Title: A tidal turbine blade
Inventor: SIDDHARTH SUHAS KULKARNI
IPC: F03B13/26
Filed: 2014-12-05
Abstract: A caudal fin shaped blade for use on a horizontal axis tidal current turbine is designed by bio-mimicking the Blue Marlin fish caudal fin. A method for forming the blade includes the steps of defining a traditional horizontal axis tidal turbine using a symmetrical airfoil comprising nine airfoil stations placed at 10 percent of the blade, determining a twist angle distribution by creating a twist angle distribution rule for root airfoil and tip airfoil and using a third order polynomial function passing through the centre of each airfoil to twist the blade from root airfoil to tip airfoil.

Title: Testing the bending behaviour of rigid pipes
Inventor: NORMAN COX
IPC: G01N3/20
Filed: 2014-12-05
Abstract: Pipe-bending rig 10 anchors an end of pipe 16 and comprises former 18, presenting a convex forming surface. Bending drive 32 exerts, possibly via wire 38, a lateral force on the unfixed end to effect plastic deformation of the pipe against the former. A carriage 28 is movable along a path, preferably parabolic and defined by parallel rails 22. A link 26 carried by the trolley 28 imparts longitudinal tension to the pipe during lateral deflection. The carriage may be moved passively by the pipe, or may have separate means (not shown) to maintain angular alignment with the pipe end. A straightening former 20 and corresponding drive 34 may also be present, opposed to and having a greater radius of curvature than the convex former. The rig may be used for pipes with composite structure, the rig simultaneously bending and tensioning a pipe for testing purposes, as occurs during spooling.

Title: Gear change system incorporating simultaneous selection of multiple gears
Inventor: WILLIAM R ABBOTT
IPC: F16H31/00
Filed: 2015-05-19
Abstract: Drive gears 1 incorporate a standard, or actuated, freewheel 8 that allows each gear to rotate at a different speed to the other drive gears. The drive gears maybe mounted coaxially about a drive shaft 4 with gear selection by means of actuating the freewheel, also called an overrunning clutch or one-way clutch, incorporated within each gear. Each freewheel may be driven by a separate motor (5.2 fig. 5). Driven gears 2 on the output shaft 3 can remain permanently meshed with drive gears. The system can provide a compact, clutchless continuously meshed gear system that does not have a neutral phase, therefore the system results in quicker gear changes as multiple gears remain selected with only the highest gear actually driving the load.

Title: Group III-N transistors on nanoscale template structures
Inventor: THEN HAN WUI
IPC: H01L29/78
Filed: 2013-06-24
Abstract: A III-N semiconductor channel is formed on a III-N transition layer formed on a (111) or (110) surface of a silicon template structure, such as a fin sidewall. In embodiments, the silicon fin has a width comparable to the III-N epitaxial film thicknesses for a more compliant seeding layer, permitting lower defect density and/or reduced epitaxial film thickness. In embodiments, a transition layer is GaN and the semiconductor channel comprises Indium (In) to increase a conduction band offset from the silicon fin. In other embodiments, the fin is sacrificial and either removed or oxidized, or otherwise converted into a dielectric structure during transistor fabrication. In certain embodiments employing a sacrificial fin, the III-N transition layer and semiconductor channel is substantially pure GaN, permitting a breakdown voltage higher than would be sustainable in the presence of the silicon fin.
