Abstract: For an automobile with a gasoline fuel system wherein fuel is delivered by a fuel pump from the gas tank to a carburetor and on to the engine through an intake manifold, a substitute non-petroleum fuel system including a storage tank from which liquid fuel is pumped to an atmospherically maintained vaporization tank fitted with a heating coil. Mixed air and fuel vapors, the flow being regulated through a second accelerator, are fed directly from the vaporization tank to the intake manifold of the engine. The vapor tank is also equipped with an electrical resistance heater to facilitate engine starts. An alternative embodiment teaches mechanical linkage and circuitry for selectively operating either the gas or substitute fuel system through a single accelerator pedal.

Abstract: A method and apparatus for aligning the longitudinal margin of a loose sheet piling section above the mating margin of a set piling section to permit the piling sections to interlock. A base which supports a movable jaw mechanism is positioned on top of the set piling section. The jaw mechanism receives the loose piling section and includes rollers which guide the loose section as it is raised. When the loose section clears the top of the set section, a camming roller forces it laterally to align its margin above the mating margin of the set piling section. A further embodiment includes gripping elements on the base and interchangeable templates on the jaw mechanism which accommodate piling sections of various configurations. The templates carry universally rotatable rollers which guide the loose section and shift it laterally by camming action when it clears the top of the set piling section.

Abstract: A hanger for supporting a spanner beam used in the construction of bridge decks and the like. A bracket includes a flat tongue which rests on a girder and opposed side plates which receive one end of the spanner beam therebetween. A camming pin is inserted through opposed openings in the side plates and rotated to become tightly lodged in a supportive position beneath the spanner beam. A Z-shaped accessory plate may be used to support the bracket in an alternative position a short distance below the top of the girder. A leveling mechanism which rests on top of the girder receives the bracket tongue and is adjustable in order to vary the elevation of the spanner beam.
