  • Patent number: 12377732
    Abstract: A shunt apparatus includes a mounting bracket assembly configured for connection to a vehicle, an actuator connected to the mounting bracket assembly, and a shoe unit connected to the actuator. The actuator is controllable to move the shoe unit to an extended position where a conductive shoe of the shoe unit is positioned to contact a conductive first running surface on which the vehicle travels. The shoe unit includes a resilient biasing assembly that is configured to exert a force on the shoe, to press the shoe against the running surface during movement of the vehicle. Two of the shunt apparatuses may be attached to opposite sides of the vehicle. The shoes of the two shunt apparatuses are electrically connected to one another by an electrical cable. When the shoes are brought into contact with respective running surfaces, the running surfaces are electrically shunted for vehicle signaling purposes or otherwise.

  • Patent number: 11938829
    Abstract: A third rail paddle system includes a support assembly configured for attachment to a vehicle, a pivot connection attached to the support assembly and that defines a range of up and down movement, and a third rail paddle assembly having an arm unit and a paddle. The paddle assembly is attached to the pivot connection for the paddle to contact a third rail and move up and down relative to the third rail when the support assembly is attached to the vehicle. One of the pivot connection, the paddle assembly, or the support assembly includes a stop element that limits the range of the up and down movement and prevents the paddle assembly from moving downwards to a bottom of the range of movement.

  • Patent number: 10926989
    Abstract: A dispensing unit is operatively associated with a refrigeration appliance for selectively dispensing water and ice at a dispensing station. The dispensing unit includes an actuator that is movable to selected positions in order to support the dispensing of the water and ice. The dispensing unit can include a passageway through which ice is dispensed, and an ice door can be provided for selectively opening and closing the passageway to the dispensing of ice. In one aspect, the ice door can be opened and closed mechanically and in another aspect, the ice door can be opened and closed electromechanically. The dispensing unit also can provide for the position of a water-dispensing nozzle to be adjusted for the purpose of dispensing water to receptacles outside a recessed area at which the nozzle is located and to provide for the activation of illuminating devices to indicate operating conditions at the refrigeration appliance.

  • Patent number: 10451328
    Abstract: A refrigerator with a freezer compartment having a door to open and close the freezer compartment. An ice maker is disposed within the freezer compartment for forming ice pieces. An ice storage bin is mounted to the door for receiving ice from the ice maker. A cover is hinged to the ice marker. The cover is moveable between an unrestricting position in which ice is discharged when the door is in a closed position to a restricting position in which ice does not discharge when the door is in an open position. A sliding tray having sidewall enclosing an area behind the ice maker and extending the depth between the ice maker and a rear wall of the refrigerator, defines a storage chamber.

  • Patent number: 10077183
    Abstract: A refrigerator includes a cabinet defining a fresh food compartment and a door pivotally mounted to the cabinet and including an interior surface in communication with the fresh food compartment when the door is closed. A shelf unit is disposed adjacent the interior surface of the door, and a container is supported by the shelf unit. A fill mechanism is positioned vertically above the container and the container is configured to receive liquid from the fill mechanism. A sensor is configured to sense a property of the container or liquid received in the container. A control is in communication with the sensor and regulates a dispensing of liquid into the container based upon the sensed property. The sensor utilizes a capacitive sensor located adjacent to the container.

  • Patent number: 9557097
    Abstract: A refrigerator includes a cabinet defining a fresh food compartment and a door pivotally mounted to the cabinet and including an interior surface in communication with the fresh food compartment when the door is closed. A liquid dispenser is arranged on the interior surface of the door, and a container is supported on the door and configured to receive liquid from the liquid dispenser. A sensor is configured to sense a property of the container, and a control is in communication with the sensor. The control is configured to regulate dispensing of liquid into the container based upon the sensed property of the container. In one example, the sensor is resiliently biased into contact with the container to sense a property of the container. In another example, the control indicates a stale liquid condition if a timer expires before the container has been removed from the door.
