  • Patent number: 5839485
    Abstract: A method and apparatus for filling a container with a magnetic material using an electromagnetic valve and a demagnetizing circuit to control the flow and properties of the material. Initially an empty container is placed under a fill tube through which the material will be supplied to the container. In the filling process an auger located inside of the fill tube rotates to move the material through the fill tube. When the container is filled, the auger stops rotating and the electromagnetic valve is actuated. The electromagnetic valve supplies a magnetic field which holds the material particles in place, plugging the fill tube with the material. The filled container is removed from the fill tube and an empty container is put in its place. When the electromagnetic valve is switched off, a demagnetizing circuit is activated. After the material particles are demagnetized the auger is switched on and the material flows again to fill the container.

  • Patent number: 5249612
    Abstract: Devices and methods are disclosed for controlling the dispensing of fluid, particularly hazardous or flammable fluids, such as automobile gasoline. A recurring problem is the dispensing, particularly by untrained members of the public, into unsuitable or unapproved containers or into no container at all, which can cause leakage, fire, damage to the container, or environmental or health hazards. The invention detects the presence of a container closely adjacent to the outlet of the pump or other dispenser and attempts to determine whether a detected container is of a suitable type by generating a field, such as an electromagnetic field, and measuring the reaction of the container to the field, thus identifying information about selected physical characteristics of the container, such as its metallic or non-metallic material composition. Unless a suitable container is detected in a predetermined position, the invention will block dispensing of the fluid.

    Abstract: The present invention is an automatic volume fill control apparatus to be used in conjunction with a recovering device which is operable upon being electrically connected to an electrical power source. The automatic control apparatus comprises a control unit electrically interconnected between the electrical power source and the recovering device. The control unit has an electrical circuit which includes an electrical relay switch and connects with a float switch installed in a recovered refrigerant tank. The float switch is normally closed when the refrigerant tank is less than 80% filled, which causes the relay switch to be closed to establish electrical connection between the power source and the recovering device, so the filling of the refrigerant tank continues. When the refrigerant in the tank reaches 80% in volume, the float switch will be opened, which causes the relay switch to open to cut-off the electrical connection between the power source and the recovering device, so the filling process stops.
