  • Patent number: 11377888
    Abstract: A remanence-eliminating magnetic lock includes a housing, an electromagnetic body and a resilient abutting member. The electromagnetic body can be assembled into the housing and receive externally-supplied electricity to generate a magnetic attraction force on a top surface thereof. The resilient abutting member has a fixing end to be fixed within the housing or the electromagnetic body, and an abutting end exposed from the housing or the top surface of the electromagnetic body. A peak of the abutting end is higher than the top surface of the electromagnetic body. When a metal member is magnetically attached to the top surface of the electromagnetic body, the metal member pressures the abutting end to deform. When the supply of electricity to the magnetic lock is cut off, the abutting end pushes the metal member through a restoring force thereof to move the metal member away from the electromagnetic body to eliminate remanence.

  • Patent number: 11136785
    Abstract: An elevator call box with internal, concealable latching mechanism comprises an internally disposed, cylindrical magnetic pin with a relatively low pull force that is slidably displaceable by an larger, external magnetic force supplied by a service technician. When the access door is closed, magnetic pin penetrates an orifice in a locking tab to lock the call box. The pin magnet is normally attracted to an adjacent, magnetically attractive clip snap-fitted to a latching block. The latch is externally disengaged via a stronger portable magnet carried by service personnel. The larger magnetic pull force of the portable magnet slidably displaces the smaller magnetic latch pin, freeing the locking tab to permit pivotal opening of the access door. Once the stronger magnet is moved away, the smaller magnetic pin, which is attracted magnetically to the clip, will return to it's rest position penetrating the locking tab and locking the control.

  • Patent number: 10450776
    Abstract: An electromagnetic lock assembly includes a magnet block having a coil assembly and a connection for receiving an electrical current; and a control system having a detection circuit and an activation circuit, wherein the detection circuit senses a voltage across the coil and automatically sends an activation signal to the activation circuit when the voltage decreases from a supply voltage to a reference threshold voltage, the activation circuit increasing the electrical current through or the voltage across the coil assembly upon receipt of the activation signal. The electromagnetic lock assembly may further include an armature for coupling with the magnet block, wherein the supply voltage is configured by the control system to magnetically couple the armature and the magnet block absent an external separating force applied against the armature or magnet block.

  • Patent number: 10366854
    Abstract: A contactor includes a plurality of switches mechanically coupled to an actuator. The actuator is moveable between operational and tripped positions. Switches that are closed in the operational position are open in the tripped position, and vice versa. The actuator extends through a coil as a core. The coil moves the actuator when an input signal is applied to the coil. A first input circuit receives a power-up input signal to transition the contactor from a tripped position to an operational position. A second input circuit receives a trip signal to transition the contactor from the operational position to the tripped position. First and second switches, coupled to respective first and second ends of the coil, reverse the polarity of the coil each occurrence of the actuator being actuated in preparation for the coil to be energized and magnetically polarized in an opposite direction during a next subsequent actuation.

  • Patent number: 10361541
    Abstract: Method and apparatus for sealing an air vent in a switchgear cabinet provide a vent seal assembly having a vent seal cover and a set of linear guides on which the vent seal cover may be mounted. The vent seal cover and linear guides are housed within a casing attachable to an interior surface of the switchgear cabinet and directly over an air vent. Within the casing, the vent seal cover may slide freely along the linear guides toward the air vent, with no spring or other mechanical biasing mechanism to oppose the sliding of the cover. A catch on the casing releasably holds the vent seal cover to keep the air vent open during normal operating conditions. When an arc event occurs, pressure from the arc event knocks the vent seal cover free of the catch and propels it toward the air vent, quickly slamming the air vent shut.
