Title: Innovations of William Ernest Grass
Introduction
William Ernest Grass is a notable inventor based in Sussex, WI (US). He has made significant contributions to the field of electrical engineering, holding a total of 2 patents. His work primarily focuses on enhancing the functionality and safety of electrical systems.
Latest Patents
One of his latest patents is the "Remotely Operated Meter Disconnect Switch." This innovative device features multiple pairs of stationary and movable contacts that can be toggled simultaneously between open and closed positions. This allows for the disconnection or connection of a meter from a line power source through a reciprocating operator driven by a low-power clock motor. The operator is connected to the contacts via a series of pivotally coupled toggle links, which are spring-biased to maintain the contacts in either of two stable states: open or closed. The disconnect switch is designed as a modular unit that is interposed between the meter socket and the meter, enabling remote actuation and cycling of the motor through a predetermined number of degrees of rotation sufficient to change the state of the contacts.
Another significant patent is the "Circuit Breaker Incorporating Trip Coil as Shunt Resistor in Parallel." This invention features a solenoid trip unit that is electrically connected in parallel with a current-limiting polymer element in series with circuit breaker contacts. This configuration functions as a shunt resistance for the polymer element, becoming energized by the transition of the polymer element to its high resistive state. This transition triggers the breaker contacts to open. The solenoid may be particularly wound with a resistive wire, enhancing its functionality.
