  • Hull cleaner
    Patent number: 9139269
    Abstract: A boat hull cleaner comprises a pole having at least two parts 2, 3 which can be set at an angle with respect to one another, a float 6, and a brush 7, the float having a buoyancy portion which gives a minimum buoyancy to the float. The float has an opening or openings arranged to admit water into the float when it is tilted while under water with the result that effective buoyancy of the float is adjusted. The hull cleaner is formed such that when it is in use a human operator can hold one end of the pole from above water level and move it to manipulate the float and the brush beneath water level such that the float encourages the brush against a boat hull to assist the operator to clean the hull.

  • Device and process to reduce pressure and temperature loss from a solar thermal receiver
    Patent number: 8763397
    Abstract: A solar-thermal receiver with a superheater isolation valve is disclosed. The superheater isolation valve is positioned so as to impede the transfer of steam from a steam drum or vertical separator into a superheater. The decays in temperature and pressure, within components of a solar-thermal receiver system that may occur throughout the shutdown period of a solar-thermal receiver, may be reduced or minimized.
