  • Patent number: 4696329
    Abstract: An apparatus for automatically adjusting a preselected volume of material dispensed by a volumetric filling machine into containers to be filled by weight. The apparatus has a scale for sequentially weighing a plurality of containers each containing the preselected volume of material dispensed by the filling machine and sequentially generating an equal plurality of weight signals representative of the weight of the dispensed material in the containers. A microprocessor receives and stores the sequential weight signals and stores them in a memory, and calculates an average weight value. The microprocessor then compares the average weight value to a preselected weight value and generates a correction signal representative of the comparison. A controller responsive to the correction signal adjusts the preselected volume by an amount sufficient to cause the average weight value to be equal to the preselected weight value.

  • Patent number: 4694870
    Abstract: A vented fuel system for a vehicle includes a plurality of fuel storage tanks and a fuel sump tank with at least one fuel storage tank positioned on each side of the vehicle. The sump tank is positioned on the vehicle between the fuel storage tanks and at a lower elevation than the fuel storage tanks. Each of the fuel storage tanks is connected by a fuel line to the sump tank and all of the fuel storage tanks are interconnected by air transfer lines. One of the fuel storage tanks on each side of the vehicle is provided with a filler spout and a vented fuel cap assembly for closing the filler spout. All of the fuel tanks can be filled from either side of the vehicle, and during refueling, air is expelled from the closed vented fuel cap assemblies and the open filler spout. The plurality of air transfer lines prevent air entrapment in any of the tanks by transferring air between the tanks and subsequent venting of the air through either or both vented fuel cap assemblies.

  • Patent number: 4693286
    Abstract: A piston is forced in a direction to disengage from a cylinder containing a fluid such as an adhesive. The piston while in engagement with the cylinder abuts a stop in response to the disengagement force. While the disengagement force is kept on the piston, the chamber between the fluid and piston in the cylinder is evacuated. After evacuation, the disengagement force on the piston is gradually released and the piston is forced against the fluid to squeeze the fluid through fluid couplings into an array of corresponding containers releasably secured to the piston, simultaneously filling the containers without exposing the fluid to air.

  • Patent number: 4691748
    Abstract: Bottle filling machines are known in which a centering bell is attached to a bushing for vertical movement up and down on a filler tube. Downward movement of the bushing and bell is limited by a shoulder on an enlarged tip portion of the filler tube. The area of contact between the bushing and shoulder in prior art arrangements is a narrow circular flat area perpendicular to the long axis of the filter tube. Repeated contact between the bushing and the shoulder on the tube tip causes wear on the bushing and on the shoulder. The present invention reduces the rate of wear of the contact areas by forming the shoulder so that it slopes downwardly and outwardly an an angle of about 20.degree. to 45.degree. with respect to a vertical axis. The region of the bushing which engages the shoulder is also sloped downwardly and outwardly at substantially the same angle.

  • Patent number: 4688608
    Abstract: A filling valve mechanism for cans is presented. The valve includes a sleeve slidably mounted on a pair of pins and limited in downward motion by means of a stop. The sleeve carries an O-ring circumferentially thereabout for engaging within the throat of a container or can to be filled. The O-ring is of slightly greater diameter than the throat of the can such that sealing engagement is achieved. Also carried on the sleeve is a resilient compressible stripping member adapted for engaging the mouth of the can. The stripping member compresses against the mouth of the can, short of full compression by virtue of the limited downward movement of the sleeve against the stop. After the can is filled, the stripping member urges the O-ring from the throat of the can while holding the can in place.

  • Patent number: 4687031
    Abstract: A pair of flapper valves are mounted in parallel to control the flow of a fluid into a reservoir. The flapper valves are opened by a first rotatable cam which is rotated through one or more complete revolutions when a float control switch in the reservoir is opened thereby indicating a drop in the level of fluid in the reservoir. Each complete revolution of the first cam actuates an impulse switch for a short duration. The impulse switch energizes a low speed memory motor and increments the output shaft of the motor. Each increment corresponds to one complete revolution of the first cam and, therefore, one unit of a fixed quantity of fluid passing through the valves. The output shaft of the memory motor rotates a second adjustable cam that controls the actuation of a switch which in turn controls a dispenser for dispensing a chemical additive into the fluid added to the reservoir.

  • Patent number: 4681144
    Abstract: An improved below-ground apparatus and method for fueling a vehicle through an inlet on a exposed tank bottom. The apparatus is characterized by a frame carrying an upwardly-facing nozzle, a lift to move the frame and the nozzle from a fully-retracted to an intermediate position and from the intermediate position to a position for full engagement with the inlet. The intermediate position is determined by sensing the vertical position of the tank bottom and, at the intermediate position, the nozzle member is positioned on the frame in vertical alignment with the inlet prior to final lifting. In preferred embodiments, a blower creates an air ride for the nozzle member facilitating its positioning on the frame, and another blower creates a vacuum to hold the nozzle member is proper position and to eliminate fuel vapors. The nozzle member is preferably conical in shape.

  • Patent number: 4679603
    Abstract: A filling valve fills liquid from a filling machine vessel into containers. When the filling valve is opened a complete pressure equalization takes place between the vessel and the container to be filled. The container is held in the filling position by a vertically movable centering member. At the end of the filling operation, with the centering member still holding the container, a return gas tube extending into the container can be emptied and the volume of the container above the liquid level can be relieved without any inflow of atmospheric air. Further, the usual expansion below the liquid level is avoided. The centering member along with the filling valve can be lowered into the filling position by a cam disc and a pressure spring and/or assisted by the overpressure within the filling machine vessel. After movement by the cam disc the centering member and filling valve can be pressed against the container opening by the pressure spring and/or the pressure in the vessel.

  • Patent number: 4676280
    Abstract: A method of dispensing a liquid including providing a liquid containing resilient storage reservoir, positioning the reservoir in the path of traction portions a vehicle, providing a shroud which is generally outwardly open and adapted to receive a hose and storing the hose therein. The hose is removed from the shroud and secured to connector which communicates with the interior of the reservoir. The vehicle is moved over the reservoir in such a manner that the traction portions runs over at least a portion of the liquid storage reservoir in a generally longitudinal axial direction to urge the liquid out of the reservoir while resisting substantial lateral expansion of the reservoir in front of the traction portions. The method and reservoir may be employed to refuel a vehicle by connecting the reservoir with a fuel inlet of the vehicle. The hose is preferably secured within the shroud when the reservoir is not receiving or dispensing liquid.
