Title: The Innovative Contributions of Daniel Weinstein

Introduction

Daniel Weinstein is a notable inventor based in San Jose, California. He has made significant contributions to the field of engineering, particularly in the development of advanced sensor technologies. With a total of 3 patents to his name, Weinstein's work has had a considerable impact on various applications, especially in nuclear reactor environments.

Latest Patents

Weinstein's latest patents include a double cantilever beam crack growth sensor. This innovative assembly comprises a fracture specimen with a notch that defines first and second spaced, substantially parallel, outwardly extending beams. These beams terminate at a closed end where crack growth occurs and extend to an open end. The beams are interconnected along a portion of their facing surfaces by two substantially parallel ligaments, which are spaced from each other. Another embodiment of his work is a corrosive environment measuring apparatus, which includes a double cantilever beam assembly designed for use in the aqueous portion of a reactor vessel. This assembly is often utilized in nuclear reactors, where it is typically housed within a tube that can be selectively lowered into the reactor's aqueous environment.

Additionally, Weinstein has developed a method and apparatus for controlling the load on a double cantilever beam. This apparatus allows for the measurement and control of the crack growth rate within a double cantilever beam type test specimen. The test specimen's arms are equipped with pressure-actuated bellows to induce a predetermined load, along with a sensing assembly that provides feedback on beam displacement. This technology enables remote mounting and adjustment of the test specimen within the reactor pressure vessel or piping, ensuring a constant or predetermined stress intensity to induce stress corrosion cracking or corrosion fatigue.
