Patent GB-2346148-A (GB)
Title: Conducting polymers with switchable magnetic/electronic properties
Inventor: BROWN JOHN WILLIAM
IPC: H01B1/12
Filed: 1999-01-28
Abstract: A range of copolymers is provided, which exhibit switching of their electrical and optical properties under the influence of external stimuli. The general structural feature of these materials is a conjugated   f   polymer backbone which may be semiconducting or conducting. The backbone is substituted with pendant mesogens and spacer groups in either sequential block or alternating copolymer arrangements. The switching properties of these systems arise from the tendency for mesogenic pendant groups with positive dielectric anisotropy to align parallel to the applied electric field and the pendant groups with negative dielectric anisotropy to align perpendicular to the applied field. These various alignments apply torque to the polymer backbone and interupt the conjugation of the polymer producing changes in electronic conduction and electrical properties.

Title: Submersible water flow turbine with buoyancy chamber
Inventor: ARMSTRONG JOHN RICHARD CAREW
IPC: F03B13/10
Filed: 1999-03-01
Abstract: A turbine 1 to harness energy from river or sea water flows or currents has a rotor rotating about a near horizontal axis and supported by a buoyancy chamber 2. A restraining arm 3, which is rigid, telescopic or flexible, ties the turbine 1 to an anchorage 4 via a bearing 5, so that the turbine is free to follow current direction changes and accommodate water level changes. The buoyancy of the chamber may be changed by pumping air into the chamber 2 and water out, to adjust power output and blade tip clearance. Sufficient air can be used to cause the turbine to flip over (fig 3), lifting the rotor clear of the water for maintenance. The chamber 2 may be streamlined, or have rotors on side arms (fig 4), and may include a sealed tank and a tank in which the amount of air and water may be trimmed. An electricity generator in the turbine may be used as a brake. Electricity may be removed by an armoured cable, a controllable rudder ensuring that the turbine swings so as not to wind up the cable in the event of tide change.
