  • Patent number: 10400577
    Abstract: Diversion material is particulate material used during wellbore treatment to temporarily seal a wellbore fluid passage such as a fracture. A method and apparatus for diversion material testing permits simulation of wellbore fracture parameters and testing thereof against a selected diversion material. The apparatus comprises: a fluid piping system including a fluid inlet end and a fluid outlet end; a fracture simulator chamber including a fracture-simulating outlet slot through a wall of the chamber, the fracture simulator chamber being releasably connectable to the fluid outlet end; a pump to pump fluid through the fluid piping system from the fluid inlet line to the fluid outlet end and into the fracture simulator chamber; a diversion material launch system connected in communication with the fluid piping system between the fluid inlet end and the fluid outlet line; and a pressure transducer in the fluid piping system to measure pressure in the fluid piping system.

  • Patent number: 7449117
    Abstract: A filtration unit that includes a casing that has a closed bottom and is immersed in a water storage tank (or water storage pond) into which raw water is introduced, the casing being composed of a introduction port which introduces the raw water in the water storage tank into the casing, an active carbon supply device which adds active carbon to the introduced raw water, an agitator which agitates the raw water inside the casing to which active carbon has been added, a filtration module which filters the raw water, a back flow preventing device which prevents the raw water inside the casing from flowing back into the introduction port and being discharged into the water storage tank, and a discharging device which discharges the raw water from the casing.

  • Patent number: 7252204
    Abstract: A combination lock container (10), suitable for accepting a wine bottle, consisting of an upper housing (12), a lower housing (50), a plurality of tumblers (18A-18E), and externally applied indicia (24). Cylindrical walls, or skirt portions, of each housing nest and engage into one another. Each housing has a key-like feature, consisting of a linear array of tabs with gap spacing between, that projects radially from the outer cylindrical wall surface. The upper housing has a longitudinal slot opening in the cylindrical wall, adjacent to its set of tabs, which can accept the tabs of the lower housing. When the housings are fully assembled, matching tab and gap features on each housing are adjacent and in lateral alignment with respect to each other. A plurality of tumblers, each with an internal annularly formed locking rib, are placed concentrically around the housings.

  • Patent number: 6240985
    Abstract: A remote filling device for use with a shipping container is described. A shipping container with specialized connections can be remotely opened using a single lightweight tool using a single drive screw latching mechanism. The actuation of the latching mechanism also compresses seals between the filling device and dewatering connections on the container. Dewatering is accomplished using reusable, backwashable filters. Once the container is filled and dewatered, the filling device is remotely removed and a lightweight, reusable lid is remotely scaled to the container using a single screw latch remotely actuated.
