  • Patent number: 8323359
    Abstract: A crystallizer system for forming solid crystals includes a vessel defining a cylindrical sidewall, a sparge device located at a bottom of the vessel, a plurality of impellers attached to a shaft, and a plurality of redistribution funnel assemblies vertically spaced apart. Each funnel assembly may be positioned underneath a respective impeller of the plurality of impellers. Each funnel assembly may include a funnel, a disc attached to the shaft such that the disc rotates with the impellers, and a channel extending radially inward from a location near the sidewall. The channel may be adapted to direct gas bubbles from the sidewall to a location near blade outer edges of the respective impeller A lower edge of the funnel and the disc may define a lower gap therebetween, such that solid particles falling from within the funnel are directed out of the lower gap when the disc is rotated.

  • Publication number: 20120147513
    Abstract: A portable, in-line conveyor grounding system includes an electrically conductive metal pipe having a material flow section, with an inner diameter greater than that of an inlet and outlet, and a metallic grating disposed in the material flow section. An inlet attachment device and an outlet attachment device, as well as an electrically conductive wire with a grounding clamp, is provided. An electrically insulating wrapping is wrapped about the conductive wire and electrically conductive pipe, with a section of the wire having the grounding clamp exposed.
