Abstract: A portable screen includes a conveyor which has a working position in which it extends out the end of the chassis, swivels, raises and lowers, and has a storage position in which it folds flat against the side of the chassis.

Abstract: An improved mounting system for mounting a forklift on a carrier vehicle where the forklift includes a frame, a mast connected to the frame, and a fork carriage having a pair of forks extending therefrom. The fork carriage is adapted to be vertically displaceable on the mast and laterally extendable relative to the mast. The carrier vehicle includes a mounting end with at least one fork receiver adapted to receive the pair of forks therein and to allow complete lifting of the forklift off of a ground surface by vertically displacing the fork carriage. At least one hook is attached to either the mast of the forklift or the mounting end of the carrier vehicle, and an engagement bar is secured to the other of the mast or the mounting end. The engagement bar is sized to be received within the at least one hook to thereby securely mount the forklift to the mounting end of the carrier vehicle. In one embodiment the at least one hook is two hooks rigidly attached to base portions of the mast.

Abstract: An optimized wireless communication system includes an enhanced communications transport protocol to reduce the overhead required by the system and intelligent protocol agents (IPAs) that process and optimize standard applications before passing them on to the transport protocol.

Abstract: A compact, programmable palletizer and method for forming at least one layer of packages on a pallet, comprising a rigid frame, an infeed conveyor positioned adjacent the frame for conveying successive packages into the palletizer, and a rollerbed assembly mounted on the frame and positioned juxtaposed the infeed conveyor for receiving successive packages from the infeed conveyor. The rollerbed assembly is formed on a single horizontal plane and is movable between an advanced position and a retracted position. The palletizer further includes a fixed back stop positioned adjacent the rollerbed assembly and rigidly connected to the frame for preventing the packages conveyed onto the rollerbed assembly from moving beyond a predetermined position thereon, and a sweeper arranged adjacent the rollerbed assembly and the fixed back stop for positioning the package in a predetermined position on the rollerbed assembly by rotating, displacing and squaring the package thereon.
