  • Patent number: 8587392
    Abstract: A MOC operator structure for a circuit breaker includes linkage structure coupled between the operating mechanism and an interface structure. An armature is associated with the linkage structure. Permanent magnet structure is associated with the circuit breaker and is disposed generally adjacent to the armature. Wherein, when the operating mechanism is coupled with the linkage structure and the operating mechanism moves in a first direction, a portion of the linkage structure moves in a first direction and moves the MOC operator structure to an open position, with the armature being magnetically engaged with permanent magnet structure to maintain the MOC operator structure in the open position. When the portion of the operating mechanism moves in a second direction, the portion of the linkage structure moves in a second direction and moves the MOC operator structure to a closed position, with the armature magnetically disengaging from the permanent magnet structure.

  • Patent number: 8486718
    Abstract: A magnetic system for biosensors is switchable between attraction force and repulsion force near the sensor surface. The magnetic system includes a magnetic source and a sensor. The sensor corresponds with the magnetic field in a way that the magnetic source creates inhomogeneous magnetic field lines that results in a magnetic force towards the magnetic system and which subsequently or adjacently exerts a magnetic force directed away from the magnetic system with all magnetic forces generated at the same magnetic source.

  • Patent number: 4891617
    Abstract: A molded case circuit breaker is provided with rubber stop assemblies disposed between the contact assemblies adjacent the outside poles and the cover portion of the housing. The rubber stop assemblies are disposed such that they prevent the contact assemblies from damaging the cover. The stop assemblies include a dual purpose U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin which defines a pivot point for the crossbar assembly. The other set of arms is also provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. The shock absorber assembly is mounted adjacent outside poles above the contact carrier but spaced away from the inside of the cover of the circuit breaker. Thus, when the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover.

The movable contact arm is pivotally mounted and structured to strike the stop means as the contacts are separated and being blown open during short circuit conditions and, after the circuit breaker is tripped, the collapsed toggle assembly of the operating mechanism shifts the movable contact arm away from the stop means and allows the arm to move an additional distance away from the fixed contact and thus increase the gap distance between the opened contacts.
