  • Floating wastewater evaporator
    Patent number: 7448600
    Abstract: A working pontoon raft has frame that supports a plurality of high speed evaporator fans. An on board pump draws wastewater from under the raft and feeds it to the fans. Large amounts of wastewater from industrial reservoirs, such as oil drilling reservoirs, are evaporated into the air in an environmentally friendly manner. Power is supplied to the raft via hydraulic lines. A land base generator supplies the hydraulic power. The entire system fits on a custom trailer.

  • Fluid level measuring system
    Patent number: 7421895
    Abstract: A fluid level measuring system comprising a fluid level sensor is disclosed. The fluid level sensor may comprise a top or bottom mounted transducer and limited openings to enable accurate measurement of a fluid's depth while the fluid is moving. The fluid level measuring system may be calibrated without the use of calibration reflectors and may be used to retrofit prior art fluid level measuring systems. A control system may be used to control the fluid level sensor and interface the fluid level sensor to an external subsystem, such as a fuel gauge.

  • Dual head piston engine
    Patent number: 7412949
    Abstract: A gas or diesel internal combustion engine of either a two or four stroke design uses both ends of each piston to create a combustion chamber. The piston rod rides linearly through a lower cylinder head. The lower cylinder head forms a lower combustion chamber with its own set of valves and fuel/air inlet. A second set of lower cams and camshaft operate the lower set of valves. Crankcase oil is pumped up the middle of the piston rod to an outlet in the center of the piston.

  • Compact multi-frequency feed with/without tracking
    Patent number: 7408427
    Abstract: A method and apparatus forming an efficient and compact waveguide feed with all components for processing signals in multi-frequency band antenna feeds with single/dual linear/circular polarizations with/without tracking. The layout can be realized in a split block configuration using any number of fabrication methods, such as brazing, electroforming, and machining and is most effective when it is realized in a split-block construction, in which the waveguide components are formed in the recesses split about the zero current line. This layout results in a very compact feed, which has excellent electrical characteristics, is mechanically robust, eliminates flange connections between components, and is very cost effective.
