Title: Roger Alexander Sutherland: Innovator in Actuation and Heat Recovery Systems

Introduction

Roger Alexander Sutherland is a notable inventor based in Derby, GB. He has made significant contributions to the fields of actuation systems and heat recovery technologies. With a total of 4 patents to his name, Sutherland continues to push the boundaries of innovation in engineering.

Latest Patents

Sutherland's latest patents include an innovative actuator control system. This actuation system comprises a fluid supply that is fluidly connected to a position control actuator. The output of the position control actuator is determined by the fluid supply, which is controlled by a piezoelectric actuator. Another significant patent is his heat recovery system. This pulsed pressure heat recovery system includes a pressure vessel for holding a vaporisable first fluid. The vessel contains a heat exchanger and provides communication to the heat exchanger for the flow of a heated second fluid. The heat exchanger enables heat transfer from the second fluid to vaporise the first fluid. The system also includes a flow loop for the first fluid extending from an outlet of the vessel to an inlet to the vessel, having in series: a first non-return valve, a turbine, and a second non-return valve. The first non-return valve allows the vaporised first fluid to flow from the vessel to the turbine when the pressure of the vaporised first fluid in the vessel exceeds a predetermined limit. The turbine extracts energy from the expansion of the vaporised first fluid, while the second non-return valve prevents flow reversal around the flow loop between the turbine and the inlet.
