Abstract: A liquid mass measurement and fluid transmitting apparatus includes a container for measurement of a mass of fluid therein. A sensor is coupled to the container which measures a mass of fluid within the container independent of variations of pressure within the container. A diaphragm sensor may be located on the bottom of the container whereby electrical signals representing the mass of fluid within the cylinder are created by movement of the diaphragm caused by the mass of fluid thereon. A pressure equalizer which equalizes the pressure within the container to the pressure on the opposite side of the diaphragm allows the measurement of the mass to occur independent of any variations and pressure within the container. Liquid within the mass of liquid within the container can be accurately measured such that a desired mass of liquid may be transmitted for further use. The liquid may be vaporized and transmitted as a vapor.

Abstract: In an arrangement for limiting the fill level in a fuel tank having a filler neck with a tank inlet end, a valve flap is pivotally supported in the inlet end such that, in an open position, the valve flap is pivoted toward the fuel flow entering the tank during refueling and is connected, by way of a crank arm and a coupling rod to a float which is disposed in an essentially vertical guide tube. The coupling rod extends through the float and has spaced top and bottom stops providing for lost motion coupling between the float and the coupling rod whose weight is sufficient to keep the valve flap in an open position. When the fuel in the tank lifts the float and, after the float engages the top stop, lifts the coupling rod, closing movement of the valve flap is initiated which is then fully closed by the inflowing fuel utilizing the lost motion distance between the float and the bottom stop of the coupling rod.

Abstract: An automatic irrigation device for plants which is automatically activated in correlation with the evapotranspiration needs of the plants comprises an open-top fluid evaporation pan containing the irrigating fluids, the fluids being capable of evaporating from the pan, thereby reducing its weight. A fluid conduit attached to a fluid inlet port conducts the fluids to the plants and the pan while a valve, interposed between the inlet port and the conduit and operatively connected to the pan, controls the conduction of the fluids to the pan and the plants. A counter-force member exerts a force on the pan in a direction opposite to that of the force of gravity. When the pan holds more than a first amount of fluid the valve closes and the device enters the evaporating stage. When the pan holds less than a second, lesser amount of fluid the valve opens and the device enters the irrigating stage. The device can be used to automatically irrigate a large number of plants simultaneously.

Abstract: The surface of the intravenous liquid in a container is maintained at substantially constant height above the patient by suspending the container from an elastic member which stretches along an axis other than the suspension axis for the container. In this manner, the total vertical length of the intravenous unit, including the container, the elastic member and the support hook, is minimized. In a particular embodiment the elastic member is a spring oriented substantially horizontal and combined with a pulley and idler roller to redirect the suspension cord for the intravenous liquid container. In another embodiment the spring is disposed vertically along an axis parallel to the suspension axis. An alarm circuit includes one or more micro switches which are actuated by the moveable spring-attached pulley to provide an audible or visible alarm indication when the suspension spring retracts to a specified position, thereby indicating that the intravenous container is approaching an empty condition.

Abstract: The invention disclosed herein is a "fail safe" apparatus for controlling the level of a liquid in a tank. The apparatus includes a holding tank for temporarily containing the liquid. There is an access opening along the top surface of the tank so that the tank is open to the atmosphere at all times. An outlet conduit, with a swivel joint therein, connects the bottom of the tank to an ultimate use point for the liquid. One end of a delivery conduit extends into the holding tank and the opposite end connects into a source for the liquid. A fill valve in the delivery conduit is linked to the holding tank by a mechanical valve operator and an air spring is fastened to the tank. When liquid is drawn out of the tank, the air spring expands and swivels the tank to a position which opens the fill valve. Filling the tank with liquid causes the air spring to compress and swivels the tank in the opposite direction to a position which closes the fill valve.
