Dr. Mel Giberson, P.E. - TRI President Announces Recent US Patents Issued to TRI


These are the result of TRI's extensive and intensive efforts over the past 20 years to improve the efficiency and reliability of high power fluid drive, typical of Boiler Feed Pump and Fan applications. Many are also useful when upgrading existing fluid drives for sliding pressure applications and/or high turn-down ratio applications.

5,331,881 Fluid Drive Impellers and Runners machined via 3-D CAM/CNC from alloy steel forgings with integral reinforcing ring and improved vane edge shapes. Increased power and efficiency result from the optimized cavity shapes and stronger vane structure. The multi-axis CAM/CNC machining provides the necessary flexibility to precisely configure the rotating element size to the power requirement.
5,315,825 Fluid Drive Oil System incorporating a circuit oil temperature control valve and separate oil reservoir. This system improves efficiency and reduces oil leakage, foaming, and disposal. 
5,303,801 Fluid Drive Brake System. Large calipers on fold-back/removable arms provide greater breaking power, improve reliability, and simplify maintenance. The conventional master cylinder is replaced by a hydraulic intensifier and oil reservoir allowing the system to work. 
5,207,903  Filter Stand Assembly for the support of conventional filters and double circuit valves incorporating trays for draining used filter elements, and an environmentally friendly pan underneath to contain oil drips and leaks. 
5,188,170  Rocker Connection for Heat Exchangers and Pipes that permits rolling, and not the typical sliding support action. No restraint along the axis of the heat exchanger, and almost rigid support in both transverse directions.
