  • Patent number: 8973758
    Abstract: An ash basket can act as a sieve or strainer, allowing a user to lift out the charcoal from a kamado grill, clean out the ash, and place the ash basket back into the grill for future use. The ash basket retains larger pieces of charcoal that can be reused, while allowing the ash to pass through to a bottom plate of the grill. The bottom plate has openings to permit the ash to fall to an ash collection chamber. Without the ash basket, pieces of charcoal can block the openings in the bottom plate, making ash collection difficult. Moreover, with the openings blocked, proper air flow through the openings. Finally, the ash basket creates and additional air space that covers the entire surface of the interior walls by separating the ash from the wall, improving air flow, which is critical to the kamado grill design.

A crossflow classification device is used to separate large catalyst particles from catalyst fines, A slurry of a catalyst composition is introduced into the crossflow classification device. A classified catalyst composition is retrieved from a retentate produced as a result of subjecting the catalyst slurry to a crossflow classification process. The solids content of the pre-classified and/or post-classified catalyst slurry is determined by way of NMR spectroscopy. The solids content determination accounts for migration of wash liquid from the catalyst composition and into the slurry liquid phase, The classified catalyst composition has a low-fines content and produces a polyolefin composition with a low polymer fines content.

  • Patent number: 7833303
    Abstract: Sifting apparatus, for sifting solid particles from a gaseous or liquid fluid, having a rotating conical filter and fan blade assembly connected to the filter exterior, both rotated together by a motor/pulley assembly, the fan blades slanted in a direction opposite the rotation direction, so that air is drawn through the filter from its interior to its exterior, having an inlet for admission of air only at the narrow end of the filter, and having a receptacle for collection of the particles at the broad end of the filter. Applications include cleaning of particle contaminants from air; cleaning beach sand by sifting out broken glass, sea weed or other debris; extraction of mineral particles from water slurry; collection of soil samples picked up by an air stream; lawn maintenance collection of weeds, leaves and burrs; biohazard removal operations; and an alternative to auger food particle transport in food processing.

  • Publication number: 20090255856
    Abstract: The device for delivering bulk material has a supply container having a product outlet with an outlet opening which has a rectangular shape. Further, is has a perforated plate having a hole-free product inlet surface arranged underneath the product outlet of the supply container. The perforated plate serves to receive individual products from the product outlet and to move them further in a transport direction while removing broken products and dust. The hole-free product inlet surface of the perforated plate has a surface width in a direction perpendicular to the transport direction and the outlet opening of the product outlet of the supply container has an opening width in a direction perpendicular to the transport direction, the opening width corresponding to 60-95% of the surface width.

  • Patent number: 7537122
    Abstract: A portable processing plant apparatus is transported to a location convenient to a freight supplier or like destination and then set up to receive gross agricultural commodities and discharge clean agricultural commodities into a clean commodity receptacle, such as a rail car. A batch of commodity from a farm location is received into a storage bin. The batch is conveyed in a stream through a gross scale, cleaning module, and net scale and into a receptacle, such as a rail car. A gap is created between the stream of one batch and the stream of the next, and a computer is operative to control flow of the commodity streams. The computer can store batch identity information, and record the source farm location of the commodity in each receptacle.

  • Publication number: 20080202989
    Abstract: A multi-screener apparatus in which the height of the apparatus may be adjusted for the convenience of a user. This multi-screener apparatus prevents the unwanted movement of the apparatus frame without the addition of counterweights or excessive frame mass to prevent the unwanted movement. Also, this multi-screener design may function with a variety of power sources, including electrical and fossil fuel based power sources. The unit is easily placed in a desired location by optional vehicle attachment means for towing as well as gripping handles and wheels for manually positioning the apparatus in a desired location. Further, the lightweight design of the apparatus also plays an important role regarding the mobility of the apparatus.

  • Patent number: 7373996
    Abstract: A method of separating drilling/production fluids from solid cuttings from a mixture received from down hole, without the use of shale shakers, de-sanders, or de-sanders, through the steps of flowing the mixture from the well bore into a flow line above the surface of a well; next, flowing the mixture into a single separation zone of a size capable of receiving the mixture directly from the flow line on a continuous basis; circulating or centrifuging the mixture to a desired RPM within the separation zone; providing a liquid permeable barrier surrounding the mixture as the mixture is centrifuged within the separation zone; collecting the liquid in a first retrieval zone after the liquid has penetrated permeable barrier; and collecting the solids that could not penetrate the permeable barrier in a second retrieval zone within the barrier.

  • Patent number: 7322882
    Abstract: A drive linkage is described for reciprocating a sieve that is suspended within a frame of a combine harvester for movement in mutually orthogonal directions. The drive linkage comprises a cranking mechanism for imparting a reciprocating motion to the sieve in the direction of travel of the harvester and a pivot arm pivotably connected at one end to one side of the sieve to cause the sieve to move in an arc centered on a pivot axis at the opposite end of the pivot arm as the sieve is reciprocated. In the invention, the pivot axis of the pivot arm is displaced relative to the frame in synchronism with the reciprocation of the sieve in such a manner as to cause the sieve to follow a substantially rectilinear path relative to the frame.
