Abstract: A gas valve apparatus is configured to receive a gas specific adapter. The apparatus includes a gas valve body having a first end configured to be coupled to a gas connection and a second end. A keyed body is configured to receive the second end of the gas valve body. The keyed body has a first keying mechanism. The apparatus also includes a cap coupled to the keyed body. The cap includes a keyed front face having a gas outlet configured to receive the gas specific adapter. The cap also includes a second keying mechanism configured to mate with the first keying mechanism on the keyed body to permit the cap to be coupled to the keyed body.

Abstract: A swiveling fluid connector includes a flexible fluid conduit connected to a check valve mounted for rotation. The flexible fluid conduit is connected between the check valve and a stationary fluid conduit. The check valve is mounted for rotating considerably with respect to the stationary fluid conduit. The flexible fluid conduit flexes to allow for rotation of the check valve relative to the stationary fluid conduit, and maintains leak-tight communication between the check valve and the stationary fluid conduit. The check valve extends through an aperture in a plate mounted in a gas services unit. Flanges on opposite ends of the check valve cooperate with the opposite surfaces of the plate to retain the check valve in the aperture, yet allow rotation of the check valve. The rotation of the check valve is limited to an acceptable range by the cooperation between protrusions and stops. The protrusions are connected to and travel with the check valve.

Abstract: The system of the present invention generally includes a base member, a plurality of frame members and means on the frame members and the base member for securing the frame members in an upright position at selected intervals along the length of the base member. The system further includes means on the frame member for receiving between adjacent pairs of the frame members a cabinet component.

Abstract: An apparatus for the positional adjustment of cutting tools for use on machine tools has a first block having a gauging surface mounted thereon and translationally and swivelly movable on a perpendicular shaft. A second block is coupled to the first block in such a manner that the two blocks move together translationally with the first block being free to swivel relative to the second block. The second block carries indicating means for indicating the amount of translational movement of the two blocks.

Abstract: A dolly including a frame together with an a plurality of casters mounted on the frame for low friction movement of the frame along a supporting surface together with elevating mechanism mounted on the frame and spaced below a part of the load when the dolly is inserted underneath the load, the elevating mechanism being operable to engage and to impart upward movement to the load and out of engagement with the supporting surface so that easy transport of the load is accommodated.

Abstract: A method and an apparatus for unloading hopper cars. The method includes the steps of placing a tube in the vicinity of an open hopper of the hopper car, and discharging a blast aerator through the tube. The apparatus includes a housing rotatably mounting the tube. The tube includes a tip to assist in entering the material to be unloaded. A motor to rotate the tube is mounted in the housing; and, a blast aerator is receivable on the housing. A fitting seals between the stationary blast aerator and the rotatable tube, and the fitting can receive an adapter to vary the size of the blast aerator.
