Abstract: Automated cold storage unit and systems for storing, monitoring, and maintaining a supply of temperature sensitive pharmaceutical and/or other products in compliance with regulatory requirements are provided. Such units contain an array of independently addressable holding locations for containers with product in one or more controlled temperature zones fitted with temperature sensors. The units include a reader to track product information and status. Product movement within the unit is performed by a computer-controlled robot. A user interface device, preferably in communication with an application service provider to provide remotely managed inventory management and other services, provides users with secure access to the contents of the unit and associated product data and information.

Abstract: A spindle assembly includes a main housing, a spindle mounted for rotation within the housing, a wheel hub attached to the spindle, a coupling located adjacent to an inner end of the spindle, and a disconnect shaft located within a bore of the coupling. The disconnect shaft is moveable in an axial direction between an engaged position in which a splined portion of the disconnect shaft mates with splined portions of both the spindle and the coupling to prevent the spindle from rotating independently of the coupling, and a disengaged position that allows the spindle to free-wheel relative to the coupling. A sprocket or gear is connected to an inner end of the coupling to connect the spindle assembly to a drive motor. An actuator is connected to an inner end of the disconnect shaft to move the shaft between its engaged and disengaged positions.

Abstract: A fluid control valve for controlling the flow of hydraulic fluid at a high pressure from a primary pump and the flow of the hydraulic fluid at a low charge pressure from a charge pump to cam-lobe type hydraulic motors which are used to assist in driving a vehicle. When energizing the motors, charge pressure is first delivered to the motors. Thereafter, all of the supply and return lines leading to the motors and to the primary pump and the charge pump are connected together to further increase the pressure delivered to the motors. Finally, the charge pressure line is disconnected and the supply and return lines leading to the motors are connected to the high pressure supply and return lines leading to the primary pump. When the supply and return lines leading to the motors are disconnected from the primary pump, the lines leading to the motors are drained into a reservoir. An accumulator is provided within the motors to absorb sudden pressure delivered thereto.
