Title: Roy C Johnston: Innovator in Seismic Technology

Introduction

Roy C Johnston is a notable inventor based in Richardson, TX (US). He has made significant contributions to the field of seismic exploration, holding a total of 4 patents. His innovative work focuses on enhancing the efficiency and effectiveness of seismic source devices, particularly air guns.

Latest Patents

One of Johnston's latest patents is the "Internal sleeve air release control apparatus in seismic air gun." This invention discloses a seismic source device, known in the industry as an air gun, which features internal sleeve and shuttle control. This design allows for a predetermined discharge of compressed air into water for seismic exploration purposes. The shuttle engages an internal sleeve with ports that align momentarily with exhaust ports, sealing them off before all compressed air is exhausted. This mechanism prevents further air discharge with minimal loss in acoustic output, significantly reducing pulses and enhancing the overall operation of the system. Additionally, by retaining some air in the firing chamber, the system becomes more efficient and cost-effective.

Another of his patents is the "Internal air release control apparatus air gun." This invention also pertains to a seismic source device, utilizing shuttle control to manage the discharge of compressed air. The shuttle is regulated by valve means that close the exhaust ports before the complete discharge of air from the firing chamber. Similar to his previous patent, this design minimizes secondary pulses and improves the system's efficiency and cost-effectiveness.
