A portable, hand-held computer handle that may be detachable secured to a conventional hand-held computer such as a personal digital assistant or the like. The handle preferably includes a substantially planar hand-held computer-mounting portion with an ergonomically-shaped joystick-style handle portion extending orthogonally therefrom. The handle portion includes a trigger in electrical communication with the hand-held computer such that one or more functions of the hand-held computer can be controlled by actuation of the trigger. In a preferred embodiment, the hand-held computer includes a conventional scanner or other data reader thereon, and the trigger on the handle portion activates the scanner. Preferably, the handle portion is aligned with the center of gravity of the handle and hand-held computer. More preferably, the forward and backward and side-to-side position and angle of the handle portion with respect to the computer-mounting portion is adjustable thereby allowing a user to individually adjust the position of the handle to their particular needs. In a preferred embodiment, the handle is sized to receive a conventional off-the-shelf hand-held computer, and it includes conventional connectivity jacks in electrical communication with the hand-held computer to facilitate charging of the hand-held computer and/or data transmittal and exchange between the hand-held computer and another computer system.

The device in accordance with claim 13, wherein said antifriction bearing units are each mounted floating in said housings. 15. The device in accordance with claim 13, wherein said antifriction bearing units are each supported in said housings via hydrostatic bearing units. 16. The device in accordance with claim 13, wherein said antifriction bearing units have identical structures that comprise fixed bearings. 17. The device in accordance with claim 1, wherein said adjustment devices comprise piston/cylinder units structured and arranged to axially adjust positions of at least one of said at least four rolls and said sealing units. 18. The device in accordance with claim 1, wherein said sealing units comprise seals having a dog's bone shape. 19. The device in accordance with claim 1, wherein said sealing units comprise flexible sealing arrangements. 20. The device in accordance with claim 1, wherein said sealing units, which are provided on each side of a roll arrangement formed by said at least four rolls, are embodied identically. 21. The device in accordance with claim 1, wherein said sealing units comprise first and second plates and elastic elements arranged to couple said first and second plates together for relative movement between said first and second plates. 22. The device in accordance with claim 21, wherein a face of said first plate is structured and arranged to face one of an end and a plug of said at least four rolls, and said first plate face is arranged to maintain one of sealing engagement and at least a small gap with said one of said end and said plug of said at least four rolls to provide an adequate seal for said pressure chamber. 23. The device in accordance with claim 22, wherein said first plate face comprise a groove and an O-ring located in said groove, and said O-ring is arranged to one of contact and maintain said small gap with said one of said end and said plug of said at least four rolls. 24. The device in accordance with claim 1 wherein said at least four rolls and said sealing units are structured to exhibit heat expansion characteristics, and said adjustment devices are arranged to axially adjust positions of said at least four rolls and said sealing units to compensate for the heat expansion. 25. A process for dewatering a fibrous material web in an apparatus that includes at least four rolls arranged to radially limit at least one pressure chamber, sealing units arranged to axially limit the at least one pressure chamber, and adjustment devices coupled to the at least four rolls and the sealing units, said process comprising: introducing gas into the at least one pressure chamber axially adjusting the positions of at least one of the at least four rolls and the sealing units with the adjustment devices, whereby one of sealing contact is made and a small gap is formed between the sealing units and ends of the at least four rolls to provide maintain sufficient pressure in the pressure chamber; and passing the web through the at least one pressure chamber, whereby water in the web is expelled by the gas pressure. 26. The process in accordance with claim 25, wherein the adjustment devices comprise piston/cylinder devices coupled the at least four rolls and the sealing units, and the axial adjustment of the at least one of the a
