Title: Innovations by Daniel L Hertz, Jr.
Introduction
Daniel L Hertz, Jr. is an accomplished inventor based in Red Bank, NJ (US). He has made significant contributions to the field of sealing technology, holding a total of 5 patents. His innovative designs focus on enhancing the performance and reliability of seals used in various applications.
Latest Patents
One of his latest patents is the "Multilayer, multihardness seal." This invention features an annular multilayer seal that includes a series of more than two successive layers of elastomeric material. The layers vary in hardness in the axial direction, with the outermost layers being the hardest and the innermost layer being the softest. The design allows for at least five layers, where the hardness of each layer between the innermost and outermost layers is about the average of the hardnesses of those layers. The innermost layer may have a trapezoidal cross-sectional shape, and the thickness of the other layers may vary nonlinearly from the inside to the outside surface of the seal. The hardness specifications range from a Shore Durometer A Scale hardness of 40 to 75 for the innermost layer and 70 to 95 for the outermost layer.
Another notable patent is the "Annular seal with V-cut." This invention describes an annular elastomer seal designed for both primary compression-type sealing and secondary lip-type sealing capabilities. The seal features a pair of grooves in a radial seal face that diverge with depth, forming a V-shaped cut when viewed in radial cross-section. This design allows for effective sealing even when compressive stress diminishes due to elastomer relaxation phenomena.
