Inventor: BELL GORDON DAVID
IPC: F03D9/00
Filed: 2009-02-06
Abstract: A vertical axis wind turbine comprises either a hinged vane machine or a weather cocking shielded or unshielded curved blade machine having a wheel or disc 1 at the bottom of the rotor. Multiple generators, each comprising a rotating shaft, are mounted to a base plate beneath the rotor such that the shafts extend radially of the rotor and a wheel e.g. a car tyre wheel is mounted on each shaft. The tire is in frictional contact with the disc and driven to rotate thereby. The generators could be raised or lowered for maintenance by several different methods depending on the size of the generators to bring the tyres into or out of contact with the disc. The turbine may be housed in a 'compass' shaped structure having radial wind gathering or funneling walls. May be installed in steel or cement works, oil refineries, industrial estates and redundant coal power stations. The conversion of high torque, low speed VAWTs to high speed that work on the principle that a large wheel turning slowly, can turn several smaller wheels, quickly.

Title: Image layout constraint generation
Inventor: WIDDOWSON SIMON
IPC: G06T13/00
Filed: 2007-07-25
Abstract: In a method (400) for generating a dimensionally tractable set of image layout constraints, a selected constraint is applied to limit a dimension of a highly dimensional solution space (410). Through random selection one or more unconstrained dimensions of the highly dimensional solution space are identified which, when constrained, will further limit the highly dimensional solution space to a dimensionally tractable solution space (420). The tractability of the dimensionally tractable solution space is associated with a capability of a computational resource (430).

Title: A turning device
Inventor: MARTIN JAMES
IPC: B60B19/00
Filed: 2009-03-18
Abstract: The turning device described herein presents an alternative to the conventional wheel and associated steering mechanism. The turning device has a surface gripping member (23) which contacts a surface in use. The frictional and contact forces between the surface gripping member (23) and the surface can move an object to which the turning device is attached relative to the surface. Alternatively, the turning device may remain in situ and act on a surface of an object which is required to be deflected. Only a portion of the surface gripping member (23) need be laterally deflected to turn an object. A deflection means is provided in order to deflect the surface gripping member (23). The turning device has applications in vehicle wheels for cars, golf buggies, factory machinery such as forklift trucks or transportation devices and luggage or parcel sorting devices.
