Abstract: A dock leveler for bridging the gap between a loading dock and the bed of a vehicle parked at the loading dock. The dock leveler is configured for installation on the top of the dock and is designed to rotate from a vertically-stored raised position to at least one lowered, operative position. In some embodiments, the dock leveler can be lowered either for normal operation so that the deck assembly rests on the bed of the vehicle or it can be lowered to accommodate an end-loading condition.

Abstract: The present invention is directed to the high speed detection of flaws in a disk drive. In one embodiment, a preamplifier simultaneously receives and processes read signals provided by multiple heads reading a test pattern from multiple disk surfaces to detect flaws in the multiple disk surfaces. In another embodiment, a preamplifier simultaneously provides a write signal to multiple heads that simultaneously write a test pattern to multiple disk surfaces. A further embodiment reduces the time needed to detect flaws by writing a test pattern during servo track writing.

Abstract: A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly biased to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power. The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads. A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle.

Abstract: A dock leveler has a deck pivotally mounted to a frame. A counterbalance mechanism uses a pair of pivoting links connected together at a common point with a tension spring that is coupled at the other end to the deck. The links together with the frame and the deck form a four-bar linkage biased by the spring to counterbalance the weight of the deck.

Abstract: An automatic vehicle chock has a chock and a locking mechanism movable on a rail from a retracted position to a position where the chock is extended and held in position by the locking mechanism. A sensor moves with the chock to determine the position of the wheel to be chocked and extend the chock. The position of the sensor relative to the chock can be adjusted. The device also employs mechanical assemblies carried by the carriage assembly to retract the chock without the use of a brake. In one embodiment a cam is used to reverse the direction of the chock arm retaining spring after the chock has been engaged. In a second embodiment the chock is continuously biased to the stored position and a latch is used to hold the chock outward until it is locaked in posiion. The latch is then released and the bias to the stored position is restored so that the chock will retract when the lock is released.

Abstract: A vehicle restraint having a fixed member such as a frame mounted to a dock face and a hook movable relative to the fixed member for engaging a portion of a vehicle and restraining movement of the vehicle away from the dock. A non-contact sensor is employed to determine engagement of the hook with a portion of the vehicle. The sensor is positioned to provide an effective magnetic field in the zone of contact so that engagement with an ICC bar on the vehicle can be ascertained. The sensor may also be a sensor bar pivotally movable respect to a vertical restraining member. The sensor bar houses a sensor that determines relative movement between itself and a target to provide a signal indicative of engagement when the sensor bar is depressed by the vehicle.

Abstract: An adjustable bumper system for use at a loading dock which has a dock leveler having a deck pivotally mounted to a portion of the dock. The dock leveler has a lip pivotally attached to one end of said deck. The bumper system has a pair of support members each mounted to a portion of the dock. The support members may be pivotally mounted and extend along sides of the deck of said dock leveler. The support members may also be mounted to the dock face and move vertically. Dock bumpers are mounted to each support member and are positionable between two different vertical positions as the support member is moved. The dock bumpers project outward from the dock beyond the pendent lip and are adjustable to engage the rear of vehicles having different heights.
