摘要： An apparatus and a method for killing bacteria within an opaque liquid. The opaque liquid is moved along a high power ultraviolet radiation surface at a velocity which causes turbulent flow in the liquid. The turbulent flow mixes the opaque liquid so that all the liquid is exposed to the radiation even though the radiation does not penetrate the liquid to any significant depth. One embodiment of the invention moves the liquid in a serpentine path between multiple planar lamps which radiate UV from both planar surfaces.

摘要： Normal and superconducting magnets are employed in an electromagnetic (attractive) suspension system for MAGLEV vehicles. The super conducting magnet provides the principal magnetomotive force (MMF) to the system while the normal electromagnet compensates for dynamic or transient loads on the system that vary the suspension gap. The rapid variations are slowly compensated for by the superconducting magnet thereby minimizing heat generation by a superconducting coil.

摘要： A method and apparatus for controlling the level of power transferred through a stand-alone wind power generating system utilizing a wind turbine whose output is converted to electrical power by means of an induction generator are disclosed. In the disclosed system, the velocity of the wind incident upon the blade of the turbine is sensed by a velocity sensor. This information is then used to vary the excitation frequency applied to the generator to adjust the shaft speed of the turbine in proportion to the change in wind velocity. The excitation frequency is adjusted in accordance with a control algorithm so that the power output of the system is equal to a maximum fraction of available wind power at wind velocities below a pre-determined power/velocity point.
