Abstract: A pump system for a helicopter tanker includes an axial flow electric pump coupled to a lower end of a snorkel having a generally tubular pump housing extending along a central axis between an open upper end and an opposite open lower end serving as an inlet of the pump. An in-line electric motor is supported within the housing along the axis and has an output drive shaft mounting an impeller. A filter screen basket is mounted on the lower end of the housing to filter water for filtering the incoming water. An electric power cable extends from the motor through a the housing and is shrouded externally by a protective metal cable guard.

Abstract: A portable foldable ramp for bridging the space between ground level and a raised level such as the bed of a pickup truck, to permit the passage of the wheels of all-terrain vehicles and like products. The ramp has a pair of generally U-shaped ramp sections hingedly connected in end-to-end alignment so as to be foldable to coextensive bottom-to-bottom abutment for ease of transport. A somewhat stiff, flexible cable has its ends connected to the remote ends of the bottoms of the ramp sections to support the load. The cable is guided when the ramp sections are folded to dispose it in looped configuration within the confines of the coextensive ramp sections which intermesh when the ramp sections are folded.
