Abstract: A new and improved workstation including a base member, a first vertical mast mounted with the base member and extending upwardly therefrom, a second vertical mast disposed about the first vertical mast for vertical movement with respect thereto, a monitor shelf with the second vertical mast for movement therewith, a third vertical mast disposed about the second vertical mast for movement therewith, a work surface with the third vertical mast for movement therewith, and computing structure integrally mounted therewith.

Abstract: A closure member for a pressure vessel, the closure member including a flange member secured with the pressure vessel, a pressure vessel door supported by the pressure vessel, a ring assembly mounted with the flange member for engaging the pressure vessel door as a result of selective rotational movement of the ring assembly from an unlocked position to a locked position by the radially contracting cooperative movement of engaging members into engagement with the pressure vessel door as a result of such rotational movement.

Abstract: A mounting structure for a cylindrical window section of a pressure vessel, wherein the mounting structure includes a cylindrical outer band, a mounting block mountable within the cylindrical outer band, securing members for securing the outer band and mounting block a predetermined fixed axial distance from the end portion of the pressure vessel, and a seal member for axial movement with respect to the outer band for maintaining sealable engagement of the cylindrical window section between the seal member and the end portion of the pressure vessel.

Abstract: A new and improved workstation including a base member, a first vertical mast mounted with the base member and extending upwardly therefrom, a second vertical mast disposed about the first vertical mast for vertical movement with respect thereto, a monitor shelf with the second vertical mast for movement therewith, a third vertical mast disposed about the second vertical mast for movement therewith, and a work surface with the third vertical mast for movement therewith.

Abstract: A cutting tool guide assembly for guiding a cutting tool over a workpiece for making a precise cut on the workpiece, including an elongate rail member, a trolley mounted for movement along the length of the rail member with the trolley supporting the cutting tool for cutting operations on the workpiece, and a securing member fixed to the rail member for securing the rail member with the workpiece and a method for using same.

Abstract: A router guide assembly for guiding a router over a workpiece for making a precise cut on the workpiece, including an elongate rail member, a router trolley mounted for movement along the length of the rail member with the router trolley supporting the router for cutting operations on the workpiece, and a securing member fixed to the rail member for securing the rail member with the workpiece.

Abstract: An apparatus (A) and method for preserving living organs extracorporeally in vessel (V) having a hyperbaric chamber (C) therein. The organ (O) stored in chamber (C) is provided with perfusate (P) from a reservoir (R) which is open to the atmosphere and freely accessible for the user who may thereby change or add constituents to the perfusate (P) without depressurizing the apparatus (A).

Abstract: A control system for a hyperbaric chamber and method for doing same which provides for an initial purging of a portion of the oxygen contained in the air within the chamber until an analyzer detects that the oxygen concentration has been reduced below the oxygen concentration of air at one atmosphere absolute pressure. Having reduced the oxygen concentration within the chamber using a pressurized inert gas, valves are operated to pressurize the chamber at a desired rate to a desired value. The patient within the chamber is connected to an independent breathing system where breathing gas is delivered to the patient at substantially the same pressure as the pressure in the hyperbaric chamber.

Abstract: A closure member for a pressure vessel having a ring assembly that has a radially expansible outside diameter and an inside diameter defining a central area, with the central area of the diameter greater than one-half the outside diameter, and with the ring assembly selectively engaging the pressure vessel between a locked position and an unlocked position.
