Title: Prabhakar P. Rao: Inventor in Pressure Control and Autoclave Testing.

Introduction

Prabhakar P. Rao is an inventor based in Duncan, Oklahoma, whose work includes inventions for pressure control and high-pressure, high-temperature fluid testing. He is associated with Halliburton Company and holds 4 patents.

Latest Patents

Rao’s listed patents include a digital pressure controller and a high-pressure, high-temperature autoclave system for testing fluids.

The digital pressure controller uses a set-point mechanism to select the pressure to be maintained in a vessel. A pressure transducer measures the actual pressure and sends a corresponding electrical signal to a computer. The computer uses these signals to control a volume-adjustment mechanism, which changes the vessel’s effective volume and the amount of pressurizing fluid. A stepper motor moves a piston in precise increments to make the adjustment.

The autoclave system features a fluid chamber shaped to improve reception of the first signal arriving from a transmitter transducer after passing through a cement or fluid sample. It also incorporates an improved sealing arrangement for the chamber.

Career Highlights

Rao’s patent work addresses practical engineering challenges in pressure regulation and the testing of fluids under demanding conditions. His inventions combine sensing, computer-based control, and mechanical adjustment, as well as improvements to test-chamber design and sealing.

Collaborations

Rao is associated with Halliburton Company. His listed coworkers include Jack C. Penn and Jim Basuki Surjaatmadja.

Conclusion

Prabhakar P. Rao’s patents reflect contributions to digital pressure control and high-pressure, high-temperature fluid-testing equipment.
