Latest Patents
One of his latest patents is the "Magnetic trip means for circuit breaker." This invention is designed to automatically open a circuit breaker contact when predetermined fault current conditions occur. It features a stationary yoke, an armature that is biased away from the yoke, and an actuating coil in series with the contacts. The design includes a sealed capsule that houses a movable magnetic core, which is biased to a normal position. This core moves toward the armature during overload conditions, with its movement being controlled by the spacing of the capsule walls and a viscous fluid inside.
Another significant patent is the "Unitized motor starter." This invention provides a combination motor starter within a single insulated housing that contains multiple pole units. Each pole unit includes both a circuit breaker contact section and a contactor contact section. The design incorporates a spring-powered mechanism for circuit breaker operation and an electromagnet for contactor operation. The arrangement of current-carrying elements creates a current loop that enhances mechanical forces during high current flow, ensuring effective protection for the contactor contacts.
