Title: Innovations of James O Porteus
Introduction
James O Porteus is a notable inventor based in Ridgecrest, CA (US). He has made significant contributions to the field of engineering, particularly in the development of advanced machining processes and optical measurement techniques. With a total of 2 patents to his name, Porteus continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is titled "Machining process for metal mirror surfaces." This invention describes a method of producing uniform metal mirror surfaces that are harder than the starting material. The process involves a three-step machining technique that eliminates polishing defects and ensures spatial uniformity. The first step utilizes standard diamond turning methods, while the second step requires a negative rake angle of approximately 30 degrees, creating plastic deformation in the surface material. The final step involves machining at a top rake angle ranging from -5 degrees to +5 degrees, resulting in a uniform surface akin to regular diamond machining. An alternate method allows for a single cut at an intermediate rake angle.
Another significant patent is the "Method and apparatus for measuring optical coupling coefficients." This invention provides a novel approach to measuring optical coupling coefficients by utilizing the thermal expansion of a sample to reduce an externally applied tensile load of predetermined magnitude. The sample is illuminated with a known amount of incident energy, which causes it to expand and reduce the tension. This reduction in tension allows for a direct calculation of the coupling coefficient, α, using the known parameters of the sample.
