Title: Barry L. Maltby and Hydraulic Power Generation
Introduction
Barry L. Maltby is an inventor associated with Long Beach, California, and Sundstrand Corporation. His work includes a patent for an electric power generation system that combines a permanent-magnet generator with hydraulic drive and control mechanisms.
Latest Patents
Maltby is credited with 1 patent: “Hydraulically Driven Low Reactance, Large Air Gap Permanent Magnet.” The invention describes a hydraulic motor driving a low-reactance, large-air-gap permanent-magnet generator to produce poly-phase AC power. A servovalve adjusts the motor’s speed in response to output-power conditions, helping regulate the generator’s voltage. Protection circuitry monitors output parameters and can activate a solenoid to stop hydraulic flow if a monitored value exceeds preset limits, thereby halting power generation. In one embodiment, a second stator winding supplies another output, which is rectified to provide DC power for DC loads.
Career Highlights
The patent reflects Maltby’s work on integrating hydraulic drive systems, permanent-magnet generation, voltage regulation, and protective controls. His listed company affiliation is Sundstrand Corporation.
Collaborations
George H. Seffernick and Mahesh J. Shah are identified as Maltby’s coworkers. The available information does not specify their roles in the patent or the nature of their collaboration.
Conclusion
Barry L. Maltby’s patent describes a controlled and protected hydraulic power-generation system designed to provide regulated AC output and, in one embodiment, DC power.
