Title: Artificial Christmas trees
Inventor: LIU HON
IPC: A47G33/06
Filed: 1985-05-28
Abstract: Branches for artificial Christmas trees are formed by sandwiching one or more thin strips of plastics sheeting 30 whose side edges have been severed by a very large number of closely spaced transverse cuts so as to give transverse elements simulating the pine needles, between a pair of wires 26, 28 approximately at the longitudinal centre line of the strip and twisting the resulting composite structure at the centre of its length relative the two ends.

Patent GB-2190487-A (GB)
Title: Optical profilometer
Inventor: PETTS COLIN ROY
IPC: G01B11/24
Filed: 1986-05-12
Abstract: An optical profilometer which is suitable for measuring the profile of a curved surface uses a beam of light which is focussed on and reflected by the surface to determine variations in the surface position. As the beam of light intercepts different regions of the surface, the optical axis of the focussing system is arranged to remain along the radius of curvature of the surface. Light from laser 1 is directed via polarising beam splitter 5 and quarter-wave plate 7 onto objective lens 9 which focusses the beam onto curved surface 17. The reflected beam passes to quadrant detector 13, and any focus error produces a signal from generator 15 which moves objective 9 to correct the error; the error signal providing the measurement. The surface 17 is mounted on a mechanical handling system which moves the surface so that the light beam remains along a radius of curvature. <IMAGE>

Title: Control of a wind turbine and adjustable blade therefor
Inventor: JAMIESON PETER MCKEICH
IPC: F03D7/02
Filed: 1989-01-17
Abstract: A wind turbine generator blade includes a movable front portion 1, adjacent the blade tip, and mounted on a pivot axis 3 permitting the front portion 1 to be displaced to a "high drag" position in which it defines a slot with the remaining portion 2, of the blade and has a high negative angle of incidence thus tending to slow down an overspeeding blade. A truncated aerofoil section for the front blade portion 1 has a relatively high stalling angle, allowing the angle of attack to approach 30 DEG  without stalling of the front blade portion 1, but resulting in considerably increased total drag. The portion 1 may be actuated mechanically by means of a torsion spring 7 and a mass 11 acting through a cable 8 passing around a pulley 9. At speed, centrifugal force acting on the mass 11 enables the spring to bias the portion 1 to its high drag position. Alternative actuation arrangements including levers or hydraulic transmission are referred to. <IMAGE>
