The present invention provides a motor driven, helical screw conveyor having an impeller wheel at one end thereof. The screw conveyor is immersed in the liquid to be transferred and lifts the liquid so that the impeller may drive it through a first conduit and a first valve into a utilization device. The valve has three separate positions, the first of which permits delivery of a major portion of the fluid to the utilization device with a minor portion of the fluid being returned to the container via a second conduit. A second position of the first valve provides for flow of fluid from the container, through the first conduit, through the first valve and then directly back to the container via the second conduit. A third position of the valve is utilized with a flexible apron that encloses the utilization device so that when it is desired to clean the apparatus, a cleaning fluid is delivered through the first conduit to the utilization device and outwardly therefrom into the enclosing apron and then through the valve for return to the container via the second conduit. In conjunction with the closed loop cleaning system there is provided a filter that surrounds the helical screw conveyer.

A clevis assembly having a folding clevis for supporting an air launched missile has an attached pivot pin having a non-round cross section which rotates in a elongated hole in the sides of the clevis block in which the clevis lies in its stowed position. When the clevis is extended in position to engage the hooks on the missle ejector, the pivot pin is raised in the elongated hole to its upper position in which the non-round profile of the pin fits into the non-round profile of the elongated hole in the side of the recess in which it is mounted so that the pin cannot rotate. This provides a longitudinal restraint of the missile on the ejector because the clevis is prevented from rotation.
