Latest Patents

One of Schelhaas's notable inventions is a **Synchronous Belt Drive System**. This system features a synchronous belt made from high-modulus fibers such as glass, carbon, PBO, or aramid. It includes a driver sprocket, at least one driven obround sprocket, and a unique tensioner designed with an eccentric arm and a torsion spring that applies a biasing force. Schelhaas’s design ensures that none of the components, including the eccentric arm, pulley, or torsion spring, are axially displaced from one another. The obround sprocket has a toothed surface incorporating both linear and arcuate portions, enhancing its performance.

Another significant patent is the **Hose Anti-collapse Ribs, Systems and Methods**. This invention consists of an integral hose anti-collapse rib with a unitary structure shaped by two cantilevered portions that curve in opposite directions. The design includes a locking mechanism that secures the ends of the rib, maintaining its circular shape under stress, while allowing for a non-circular, generally spiral shape in a relaxed state.
