  • Patent number: 8994484
    Abstract: A stepped portion is formed in an outer peripheral portion of a slide core and is stepped to reduce an outer diameter of one portion of the slide core located on one axial side of the stepped portion. A first conducting portion of a ring core covers an outer peripheral surface of the one portion of the slide core and is slidable along an outer peripheral surface of the one portion of the slide core. The first conducting portion conducts a magnetic flux between the first conducting portion and the slide core in a radial direction. A second conducting portion of the ring core is configured into a form of a flange and radially outwardly extends from the first conducting portion. The second conducting portion conducts the magnetic flux between the second conducting portion and a bottom wall portion of a yoke in an axial direction.

  • Patent number: 8981884
    Abstract: A Hall effect grain level switch is positioned adjacent a grain fill opening at an upper portion of a grain enclosure. A Hall-voltage generator is coupled to the housing in a fixed position. An elongate member is pivotably coupled to the housing with the magnet being mounted adjacent a proximal end of the elongate member. A grain contact member is coupled adjacent a distal end of the elongate member. The Hall-voltage generator and magnet are positioned adjacent each other to provide a first output signal state when the elongate member extends vertically in a rest position. The Hall-voltage generator and magnet are distanced from each other to provide a second output signal state when the elongate member is pivoted to a non-vertical switched position in response to grain moving the contact member.

  • Patent number: 8975992
    Abstract: An electromagnetic drive for an electrical switch such as a circuit breaker, has at least one movable armature that can implement a lifting movement along a pushing direction for moving a movable switching contact of the switch. In a closed armature position, the armature closes a magnetic circuit through first and second magnetically conductive yoke parts. A permanent magnet produces a magnetic field for the magnetic circuit and a holding force for holding the armature in the closed position. A coil is disposed to generate a magnetic flux in the same or opposite direction as the magnetic flux of the permanent magnet. The electromagnetic drive can be readjusted after installation, where the first and second yoke parts are moved relative to one another by the permanent magnet into the adjusted state, whereupon they are fixed in position.

  • Patent number: 8957342
    Abstract: A sealed solenoid, magnetically operated electric power switch is suitable for use as capacitor, line and load switch operating at transmission and distribution voltages that includes no dynamically moving seals through the sealed container housing the contactor portion of the switch. The sealed solenoid switch includes a magnetically operated drive system with an actuator that magnetically couples across the container wall to avoid the use of a moving or sliding seal as part of the drive system. The sealed solenoid switch may also include a ballast resistor and resistor contact located inside the sealed container to avoid another seal as part of the ballast system. A magnetic latch holds the switch in a closed position, and a spring holds the switch in the closed position, to avoid the need for an energizing current to maintain the switch in either position.

  • Patent number: 8941453
    Abstract: An object of the invention is to provide a contact switching device that produces minimal hitting sound at the time of return. In the contact switching device, a movable iron core (42) provided at one end portion of a movable shaft (45) is attracted to a fixed iron core (38), based on excitation and degauss of an electromagnet portion (50), by which the movable shaft (45) reciprocates in a shaft center direction, and a movable contact (48a) of a movable contact piece (48) arranged at another end portion of the movable shaft (45) contacts and departs from a fixed contact (33a). Particularly, at the time of return, an annular flange portion (45a) provided at an intermediate portion of the movable shaft (45) abuts on an annular receiving portion (35c) of the magnet holder (35) to thereby restrict a position of the movable iron core (42).
