Title: John Taylor Armstrong: Innovator in Subsea Technology
Introduction
John Taylor Armstrong is a notable inventor based in Banchory, GB. He has made significant contributions to the field of subsea technology, particularly through his innovative designs and patents. With a total of 2 patents, Armstrong has focused on enhancing the capabilities of subsea actuator assemblies.
Latest Patents
Armstrong's latest patents include advancements in subsea actuator assemblies and methods for extending their water depth capabilities. One of his key inventions is a hydraulic pressure compensation system for valve actuator assemblies, which is particularly applicable for subsea wellhead installations. This system features a valve actuator assembly with a housing that retains a reciprocable piston, which is spring biased into a fail-safe configuration. The actuator assembly is hydraulically linked to an accumulator reservoir, which defines both a closed and an open fluid reservoir. The two chambers are separated by a membrane, allowing for effective pressure management.
Another significant patent is the shearing gate valve, which possesses downstream shear and seal capabilities. This innovative gate valve is designed to stroke sufficiently to cover the downstream seat interface and features a single shearing surface for wireline shearing. The gate incorporates an inlay of a hard ductile material, such as Stellite®, along its shearing edge, and is coated with an extremely hard material like tungsten carbide on the sealing surface. This design ensures that the gate fully covers and seals the upstream seat interface after the shear media has fallen below it.
