Abstract: ABSTRACT    A fuel tank for a motor cycle has a filling orifice recessed below the top of the tank whereby air spaces will be maintained above the fuel level at all times.   A protrusion or blister at one side of the tank at the lowest level of the tank forms a sump from which fuel enters an engine supply pipe. The pipe extends transversely below the tank and then turns upwardly to terminate at an open end above maximum fuel level thus acting as a tank vent.   Another pipe tapped from the point of upturn leads fuel to the engine.    If the cycle were to fall over on one side when the blister will be at the highest point, the tank air space will be trans-ferred to the blister effectively isolating the engine supply pipe from the fuel.   Should the cycle fall over on the other side, air will enter the open end of the fuel supply pipe to destroy any siphon which might otherwise act to drain fuel from the tank. In either case, fuel spillage will be limited to whatever small quantity is in the fuel supply pipe system.   The filler orifice is of course taken to be properly closed.

Abstract: ABSTRACT A vortex-sensing fluid flowmeter has a freely rotatable vortex-shedding body suspended in a section of conduit through which a fluid stream passes, the body being oriented generally transverse to the direction of fluid flow.  The body has an integrally formed upstream-facing portion adapted to shed a series of vortices within the fluid, which vorticoes alter-nately influence opposite lateral faces of the body, tending to produce a periodic rotation of the body about a firmly attached rotational shaft. The shaft is rotatably mounted to the conduit and passes at one end through the wall of the conduit to the exterior thereof.  A sleeve-like tube surrounds the shaft and is fastened tightly at its bottom end to the shaft and at its top end to the conduit wall to provide a fluid-tight seal around the shaft.  The tube is sufficiently flexible and pliable to exert negligible restraining for of against the rotation of the shaft. A sensing device located outside of the fluid stream and coupled to the externally protruding portion of the shaft exerts a predetermined restraint on the shaft.  This restraint limits the maximum rotation of the shaft at high flow rates, for minimizing the fatiguing stress exerted on the sealing tube, yet does not impede rota-tion at low flow rates.  The sensing device responds to the restrained rotations of the shaft, and electronic circuitry associated with the sensing device oonverts the response to a signal output indicative of the flow rate of the fluid.
