Abstract: A platform loading system having an elevator platform mounted loader unit d a magazine mounted loader unit in each magazine served by the loader system. Each loader unit consists of one cargo tray and its associated tray transfer machinery. In each loader unit a cargo tray may occupy one of two positions, an upper position or a lower position. The load to be transferred is always carried by a tray in the upper position. Transfer of weapons between elevator platforms and magazines consists of a simultaneous exchange of a loaded and empty tray between mating loader units. The loaded tray traveling in the upper position passes over the empty tray in the lower position heading in the opposite direction. At completion of tray exchange, loaded trays may be off-loaded and the now empty tray lowered to the lower tray position by a tray jacking system as required by the next exchange operation.

Abstract: A throttle control that provides accurate and reliable control for a plurty of remote air driven devices. The throttle control employs a plurality of primary valves that are built into a common body with a handle and a plurality of operating levers. The body has a single air supply port which directs air through a common chamber to all of the primary valves. In the body are formed a plurality of separate chambers that communicate the outlet air from the plurality of respective primary valves to the plurality of air conduits to supply air to the respective air driven devices. The handle has a chamber through which exhaust air has a tortious flow path to atmosphere. Each primary valve employs an air control valve and an air vent valve that are sequentially actuated by the associated operating lever. When the lever is not depressed, the control valve is closed and the vent valve is open and vents the air in the supply conduit through the handle chamber to atmosphere.
