Title: Innovations by Donald E Johnson
Introduction
Donald E Johnson is an accomplished inventor based in Cardiff by the Sea, California. He has made significant contributions to the field of gas compression technology. With a total of 2 patents, his work focuses on improving the efficiency and effectiveness of gas sealing arrangements.
Latest Patents
One of his latest patents is a method for controlling the concentricity of a member with a centering device. Conventional gas compressors utilize dry gas sealing arrangements mounted on a shaft. For these arrangements to function properly, the concentricity between the shaft and the sealing arrangement must be maintained within close tolerances. Johnson's innovative method addresses the shortcomings of past assembly techniques that failed to achieve this precision. His design includes a centering device with a first cylindrical portion that is cantilevered about the shaft, centering one end of the member. The second cylindrical portion and a transition portion provide mid-support for the other end of the member. This structure ensures a uniformly concentric mounting, enhancing the performance of gas compressors.
Another patent by Johnson also focuses on controlling the concentricity of a member with a centering device. Similar to his first patent, it addresses the challenges faced by conventional gas compressors in maintaining proper sealing. The apparatus he developed effectively controls the concentricity between the member and the shaft, ensuring optimal operation.
