Title: Innovations by James A. Sweety

Introduction

James A. Sweety is an accomplished inventor based in Houston, TX (US). He has made significant contributions to the field of subsea technology, holding 2 patents that enhance the reliability and efficiency of underwater operations. His work is particularly relevant in the context of fluid pipeline management and hydraulic couplings.

Latest Patents

One of his latest patents is a method and apparatus for remote control of an underwater valve. This innovation provides improved techniques for opening or closing an underwater valve in a subsea fluid pipeline. The system utilizes an acoustic signal transmitted from the surface to a receiver adjacent to the valve. A predetermined torquing force is applied to a shaft directly coupled to the valve stem, while rotation of the valve stem is prevented by a mechanical connection of an explosive bolt. The receipt of the transmitted acoustic signal initiates the release of stored electrical energy, which detonates the explosive bolt and breaks the mechanical connection. This process enables the pre-existing torquing force to rotate the valve stem, significantly increasing the reliability of valve operation.

Another notable patent is the radial seal hydraulic coupler. This improved hydraulic coupler is designed for interconnecting subsea fluid lines and features a radial seal between the male and female body portions. A C-shaped metallic seal is housed within the female body of the coupler, allowing for easy checking or replacement between successive mating and unmating operations. An elastomeric secondary seal is also provided, enhancing the reliability of the connection. Additionally, a wiper member cleans the cylindrical surface as the body portions are brought together, further improving the effectiveness of the seals.
