Abstract: The present invention discloses either an apparatus that is adapted for selective mounting to and demounting from a pallet jack for use therewith or a transport vehicle having an apparatus permanently mounted thereto, which can effectively and efficiently transport articles or stacks of objects, such as boxes, furniture, trays, or the like from one location to another. The apparatus comprises a housing and an article engaging and lifting member, which includes a base and a back support member for supporting the article or stacks of objects. The article engaging and lifting member is pivotally mounted to the housing, preferably adjacent the bottom of the back support member. In one embodiment, the apparatus further includes a first clamp member for maintaining the article adjacent the back support member. In another embodiment, the apparatus further includes an upper displacement member which can engage and displace an upper object from the stack of objects to reduce the effective height of the tilted stack for transport. In another embodiment of the present invention, the base is linearly moveable along the back support member for raising and lowering articles along the length of the back support member. The base comprises a plurality of laminated forks or a laminated platen projecting outwardly from the back support member.

Abstract: There is provided a cart for lifting and moving materials. The cart includes a lift mechanism for raising and lowering a support surface to lift the materials during transport. The cart also includes a motorized drive wheel assembly which provides a drive force in a forward or backward direction to assist the operator in moving the materials. The motorized drive wheel assembly has a variable vertical position relative to the cart wheels to enable the drive wheels to provide a drive force over contoured surfaces, such as near the base or top of a ramp. The motorized drive wheel assembly also includes a weight to maintain a minimum normal force for traction and includes a differential to allow the drive wheels to rotate at differing speeds to facilitate convenient steering of the cart. The cart is powered by one or more rechargeable batteries.

Abstract: There is provided a cart for transporting dies, molds, and similar objects. The cart includes a lift mechanism for raising and lowering a support surface to the height of the surface onto which or from which the die will be moved. The support surface includes a transfer mechanism for coupling to the die, either with an electromagnet or a suction device, to thereby slide the die as desired without damaging critical components on the exterior of the die. The cart also includes a motorized drive wheel assembly which provides a drive force in a forward or backward direction to assist the operator in moving a die that has been transferred onto the cart. The cart is powered by one or more rechargeable batteries. The cart enables a single operator to safely and conveniently remove, insert, and transport dies or other similar objects.

Abstract: In a field emitter structure, a method for removing a lift-off layer and an overlying closure layer. In one embodiment, a field emitter structure includes a cavity formed into an insulating layer overlying at least a portion of a first electrically conductive layer. A second electrically conductive layer has an opening formed above the cavity. The second electrically conductive layer has lift-off layer and a closure layer disposed thereon. The present invention removes the lift-off layer and the closure layer from the second electrically conductive layer according to the following method. First, the present invention immerses the field emitter structure in an etchant which attacks the lift-off layer. Next, the present invention activates a transducer immersed in the etchant to subject the lift-off layer of the field emitter structure to vibrational forces generated by the transducer. The vibrational forces, in conjunction with the etchant, causes the lift-off layer and the overlying closure layer to be removed from the second electrically conductive layer. The present invention then removes the field emitter structure from the etchant, removes residual etchant from the field emitter structure, and dries the field emitter structure using a Marangoni drying process.
