  • Patent number: 11984280
    Abstract: A remote controlled miniature circuit breaker includes a helical gear that engages with mating teeth of a slider plate coupled to main contacts of the circuit breaker, the helical gear including a flat portion to allow the sliding plate to slide past the helical gear. A unidirectional motor responds to an external signal to drive the helical gear while engaging the mating teeth of the slider plate, thereby moving the slider plate to close the main contacts. The motor is configured to respond to an external signal to resume the unidirectional rotation of the helical gear to position the flat portion of the gear to allow the slider plate to slide past the helical gear and contact a kicker lever to thereby open the main contacts. A trip lever pivotally mounted separately from the kicker lever, pushes the kicker lever to open the main contacts in a trip operation.

  • Patent number: 11875953
    Abstract: A calibration joint for a three-phase electric disconnect switch includes a linkage pipe extending through a lock ring, which includes an axial guide shaft, a threaded shaft, and a self-piercing set screw securing the lock ring to the linkage pipe. The linkage pipe also extends through a clevis housing, which includes an axial joiner shaft and a clevis bracket securing the clevis housing to an operating lever of the disconnect switch. An adjustment rod extending through the axial guide shaft of the lock ring, through the axial joiner shaft of the clevis housing, and engaging with lock nuts allows axial adjustment of the clevis housing with respect to the lock ring, and thus with respect to the linkage pipe. This, in turn, allows fine adjustment of the blade and jaws of an associated phase switch with respect to the switch actuator independent of the other phase switches.

  • Patent number: 11822394
    Abstract: A portable information handling system keyboard includes plural keys that each have a programmable variable-feel response to an end user experience with key interactions in real time. In one example embodiment, a magnetic-rheological fluid is disposed in a chamber of the key to pass through openings formed in a piston that moves downward with a keypress and upward in response to a biasing mechanism, such as a spring disposed in the chamber. Current applied to a coil around the chamber creates a magnetic field that varies the viscosity of the fluid so that key compression and range of motion associated with an input as well as key movement to a raised position are programmable to adjust based upon a sensed key position and movement.
