    Abstract: A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a vent hole and first and second passageways. The hydraulic control unit housing has an accumulator housing portion that houses a biasing assembly and a piston. The accumulator housing portion forms an accumulator chamber with the piston. The vent hole is defined in the hydraulic control unit housing. The first passageway is defined in the hydraulic control unit housing. The second passageway is defined in the hydraulic control unit housing that intersects the vent hole and is oriented at a different angle than the first passageway. The vent hole is dual purpose permitting hydraulic fluid entry into the accumulator chamber through the second passageway while air is permitted to escape the hydraulic control unit housing through the vent hole.

  • Publication number: 20180358791
    Abstract: An apparatus includes a cell pan that supports a circuit breaker within a switchgear cell, and a lift pan that carries a circuit breaker outside of the switchgear cell. The lift pan has a track for a roller on the circuit breaker. The apparatus further includes an extension rail that interconnects the lift pan with the cell pan in an aligned position. With the lift pan in aligned position, the track on the lift pan can receive the roller upon horizontal draw-out movement of the circuit breaker from the cell pan. A latch on the extension rail has a blocking position in which it blocks the roller from rolling outward off the cell pan, and has a non-blocking position in which it does not block the roller from rolling outward off the cell pan. The latch automatically moves from the blocking position to the non-blocking position under the influence of the lift pan upon movement of the lift pan into the aligned position.

  • Patent number: 10151787
    Abstract: An audible ground fault detection device may include: a pulse-width modulation (PWM) circuit to produce a pulse signal in response to an occurrence of a ground fault; and a buzzer circuit to emit an audible sound in response to receipt of the pulse signal. The device may include a power circuit configured to transfer power from the power line to the PWM circuit when a ground fault occurs in a load of the power line, and not to transfer the power from the power line to the PWM circuit when no ground fault occurs in any load of the power line. When the PWM circuit has no power, it will not produce the pulse signal. The power circuit may also provide DC power to the buzzer circuit in response to the occurrence of the ground fault. The buzzer circuit may include a passive buzzer.

  • Patent number: 10141128
    Abstract: A circuit breaker apparatus may include a housing, a circuit inside the housing for protecting the conductors and the load of the circuit, a display attached to outside of the housing, a controller, and a power control device. The display may be an electronically-alterable display that does not require power in situations other than changing its state. The power control device may provide power to the controller and the display when the apparatus is being tampered with. When the controller is powered, it may cause the power control device to cause the display to change from a state that indicates that the apparatus is authenticated to another state that indicates that the apparatus has been tampered with. The power control device may include a battery and a switch, or a power harvester, which can be configured to provide power to the controller when the apparatus is being tampered with.
