  • Broadcast spreader with a directional control assembly
    Patent number: 8074904
    Abstract: A broadcast spreader includes a directional control assembly that defines a pathway for granular material from a hopper through a discharge port and onto a rotating fan. The directional control assembly includes a first plate that is secured to and adapted for slidable movement with respect to the hopper. The first plate defines an opening therethrough that is substantially in registry with but smaller than the discharge port, thus serving to define a pathway for the granular material from the hopper through the discharge port and onto the fan. The directional control assembly further includes a second plate secured to and adapted for slidable movement with respect to the hopper and the first plate. Movement of the second plate relative to the first plate selectively opens or closes the pathway for the granular material from the hopper through the discharge port and onto the fan.

  • Non-dusting copper pyrithione dispersion
    Patent number: 6627665
    Abstract: The present invention is directed to a non-dusting copper pyrithione dispersion, comprising an admixture of: from about 20 to about 99 wt % of copper pyrithione; from about 0.05 to about 30 wt % of a dust-inhibiting agent selected from the group consisting of surfactants, polymer resins, binders, and combinations thereof; and from about 0.05 wt. % to about 80 wt % of a dispersant; wherein all weight percents are based on the total weight of the dispersion.

  • Process for preparing copper pyrithione
    Patent number: 5650095
    Abstract: The present invention relates to a process for producing a gel-free dispersion or solution of copper pyrithione employing at least one surfactant. Also claimed is the dispersion or solution itself, as well as a solid particulate copper pyrithione composition comprising copper pyrithione particles having a particle shape selected from the group consisting of rods, spheres, needles, platelets and combinations thereof, and optionally containing at least a trace amount of a surfactant on the outer surface of at least a portion of said particles.
