    • An electrostatic clamp is provided having a clamping plate, wherein the clamping plate has a central region and an annulus region. A plurality of gas supply orifices are defined in the central region of the clamping plate, wherein the plurality of gas supply orifices are in fluid communication with a pressurized gas supply, and wherein the pressurized gas supply is configured to provide a cushion of gas between the clamping surface and the workpiece in the central region of the clamping plate via the plurality of gas supply orifices. One or more gas return orifices defined in one or more of the central region and annulus region of the clamping plate, wherein the one or more gas return orifices are in fluid communication with a vacuum source, therein generally defining an exhaust path for the cushion of gas. A seal is disposed in the annulus region of the clamping plate, wherein the seal is configured to generally prevent a leakage of the cushion of gas from the central region to an environment external to the annulus region. One or more electrodes are further electrically connected to a first voltage potential to provide a first clamping force.

    • A pressure measuring device includes a resilient expandable pressure sensor element having an open end and an opposite closed end. The pressure sensor element includes spiral flutes extending between the open and closed ends defining spiral bellows. The pressure sensor element is tapered over at least a portion of its length from the open end to the closed end. The pressure measuring device also includes a supporting structure having a pressure indicating scale. The supporting structure holds the pressure sensor element such that the open end of the pressure sensor element is in communication with a fluid whose pressure is to be measured and pressure applied by the fluid causes the pressure sensor element to expand axially and be visibly displaced relative to the pressure indicating scale by a distance related to the pressure applied by the fluid.

    • A hose connection system comprises a body including an internal cavity and a port in fluid communication with a portion of the internal cavity. In addition, the system comprises a hose end fitting positioned in the cavity. The hose end fitting includes an inner tubular member and an outer tubular member concentrically disposed about the inner tubular member. The outer tubular member includes a plurality of circumferentially spaced axial slits. Further, the system comprises a plurality of wedge members arranged circumferentially about the outer tubular member. Still further, the system comprises an annular piston movably disposed within the internal cavity of the body. An end of the piston has an inner frustoconical surface that slidingly engages the plurality of wedge members. The piston is configured to move axially through the body and compress the wedge members and the outer tubular member radially inward.
