  • Publication number: 20030117890
    Abstract: A blender mixes a liquid and a quantity of particulate solids for use in hydrocarbon well operations. The blender is mounted on a vehicle having a suction manifold of rectangular tubing. The long side of the rectangular tubing is vertical, is positioned on one side of the vehicle and provides a large number of inlet connections which, in use, connect to hoses leading to tanks filled with a frac liquid or the like. The discharge manifold may be a mirror image of the suction manifold. The rectangular suction manifold tubing provides greater spacing between the inlet connections and greater volume throughput in use.

  • Publication number: 20030090958
    Abstract: A dispenser for a soft-serve food product includes a housing having a dispensing chute and a piston having a head positioned therewithin. A lateral wall, the piston head, and a front door define an enclosed hollow space. The head is slidable within the lateral wall for squeezing a deformable container to dispense product through the chute. A system for preparing and dispensing a soft-serve food product includes a tempering freezer for raising a temperature of the food product from hard-frozen to a condition for soft-serve dispensing. An apparatus for packaging a soft-serve confection into a multiple-serving-size container for transport includes a blender for blending ingredients together to form a blended product and a device for transferring the blended product into a deformable container. The deformable container filled with the blended product is transferred into a substantially rigid mold and frozen to a hardened state for transport and retention.

  • Publication number: 20010018931
    Abstract: This invention relates to a storage tank for a viscous oil containing easily polymerizable compounds. A storage tank of the present invention for strong viscous oil containing easily polymerizable compounds, comprising a bottom plate 12, a side wall 13, a draw-off pipe 3 and a inlet pipe 2. The bottom plate 12 slopes downward toward the draw-off pipe 3 and an angle of downward inclination of the bottom plate 12 is gradient at least 1/200. It becomes possible by the present inventive storage tank to effectively prevent the polymerization of the easily polymerizable compounds contained in the waste oil within the storage tank and the clogging of a pipe is suppressed considerably.
