  • Patent number: 5512179
    Abstract: A process for the separation of liquid component mixtures by combined pervaporation-vapor permeation with a feed flow in the form of a vapor-liquid mixture being employed and the feed flow being passed from bottom to top as a vapor-liquid mixture over a vertically arranged membrane, so that a permanent thorough mixing of vapor and liquid results, and no stationary liquid film is able to form on the surface of the membrane.
    Type: Grant

  • Patent number: 5417259
    Abstract: A fuel dispensing nozzle with controlled vapor recovery including a fuel passageway, a main fuel valve in the fuel passageway, a vapor recovery passageway, a main vapor valve in the vapor recovery passageway, a manually operable trigger mechanism for controlling the main fuel valve to control the flow of fuel through the fuel passageway and for opening the main vapor valve, an auxiliary vapor valve in the vapor recovery passageway for controlling the rate of flow of vapor through the vapor recovery passageway when the main vapor valve is open, a fuel flow sensing permanent magnet in the fuel passageway and moveable responsive to the rate of fuel flow, and a follower magnet connected to the auxiliary vapor valve and magnetically coupled to the fuel flow sensing magnet for opening the auxiliary vapor valve an amount correlated to the rate of fuel flow to control the rate and thus the volume of vapor recovered in direct correlation to the rate and thus the volume of fuel dispensed.
