  • Patent number: 4617975
    Abstract: A tension actuated fuel (e.g. gasoline) delivery hose uncoupler is disclosed in which, upon a predetermined tension or pressure load being applied to the delivery pump hose, the coupling will automatically uncouple thus releasing one end of the hose which, for example, may remain inserted in the fuel tank of a vehicle driving away from the fuel dispensing pump, and the other portion of the hose which is permanently affixed to the pump. The coupler includes normally closed checkvalves which, upon uncoupling of the coupler, close thereby preventing spillage of fuel. Further, the coupler is adjustable so that it may be calibrated to uncouple at predetermined tension loads.

  • Patent number: 4612964
    Abstract: A valve bag filling apparatus that combines an auger-type feed and an air pressure-type feed in a unitary filling system for filling valve bags with flowable particulate material at higher speed and with greater accuracy. A concentric tube configuration is used to deliver such material at high speed into the bag during a major portion of the filling cycle with both feed systems acting simultaneously. A novel cutoff tube closes an annular air feed passage during the final portion of the filling cycle when the auger feed portion of the system completes the bag filling operation at a highly accurate and readily controlled low feed rate. Air purge jets clear the air passage of remaining material during the final portion of the filling cycle. A unique fluidizing section of the apparatus aerates the product and feeds it into both the auger and air passage during high speed filling.

  • Patent number: 4611642
    Abstract: The present invention is directed to a bagging device for directing a flowable substance from a transport trailer to a flexible agricultural bag. The device includes a tunnel housing attached to the back of the trailer. The open end of the bag is held behind a ridge member and between the ridge member and a stretchable strap so as to resist release of bag until the bag on the ground has been filled. A tray beneath the housing supports the bottom portion of the bag to prevent it from stretching and ripping. A shield near the tires of the trailer prevent the bag from entangling in the tires. The device is especially appropriate for use with flowable commodities such as brewers grains and stillage by-product which rapidly deteriorate unless promptly stored in an air exchange-free enclosure.

  • Patent number: 4611643
    Abstract: A tubular fluid transfer device is operative by itself to seal the end of a conduit. By coupling two of the devices together, a fluid path can be selectively established between two conduits by applying heat energy. The device includes a generally planar surface having a meltable region. The generally planar surface of one device is slidable against the generally planar surface of another one of the devices to bring the meltable regions into registration. The device includes a coupling mechanism which guides the meltable regions into the desired alignment as registration occurs. Furthermore, as the meltable regions register, the coupling mechanism generates forces which bias the meltable regions into intimate contact. The coupling mechanism thereafter releasably retains the devices in this snug interlocked relationship, so that the energy can be applied to jointly heat the meltable regions and melt open a fluid path between the two devices.
