Abstract: An axial flow-type pump for separating immiscible fluids having different specific gravities and a discharge manifold fluid connected to the fluid pump for drawing of the fluid having the heavier specific gravity. The fluid pump employs a rotatable impeller mechanism having a hollow core and a decreasing axial pitch in the direction of fluid flow. The fluid interface between the pump and the discharge manifold is adjustable, so that the discharge of the fluid having the heavier specific gravity can be adjusted. The fluids are introduced into the inlet end of the rotatable impeller to produce a high velocity swirling action in the fluids and a low pressure area along the longitudinal axis of the flow line, to generate a high centrifugal force as the fluids move axially and cause the fluid having the heavier specific gravity to migrate to the perimeter. The discharge manifold is then used to draw off the fluid having a heavier specific gravity.

Abstract: A drain valve for handling contaminated fluids includes a body having a drain port and an internal passage communicating therewith. A plug is disposed in the internal passage and the plug defines a drain passage which communicates with the internal passage. Further, the drain valve includes an actuating device for selectively positioning the plug to a drain port opening position and to a drain port closing position, and a device for preventing contamination of the actuation device.

The plug sealingly engages the seal in the drain port closing position. With the seal located above the drain port, contaminates in the fluid are unable to collect thereon and thus do not abrade the seal as the plug is actuated into the drain port closing position.

Abstract: A novel valve mechanism using the so-called "rolling seal" type flexible cover tube. This cover tube is fitted fluid-tight on the outer circumference of a generally cylindrical inner movable valve member which is formed with an axial bore providing a fluid passage and which is further formed at its outer circumference with a valve port having communication with the axial bore. The cover tube has its at least one end radially turned or rolled radially outwardly to provide a turned annular lip where it is fitted on a fastened outer cylinder. Thus, the valve port is opened and closed by the outward and inward rolling motions of the annular lip of the cover tube due to the relative movements in the axial direction between the outer cylinder and the inner valve member. By the use of the valve mechanism thus constructed, a charging valve for a gas lighter can be provided.

Abstract: A needle valve nozzle is employed in a hot melt adhesive gun used to apply thermoplastic adhesive. Actuation of a trigger mechanism supplies pressurized gas to a nozzle chamber which urges the nozzle in an outward direction to an open position, the needle remaining stationary during operation of the nozzle.
