  • Patent number: 10981186
    Abstract: In a method of coating a particulate material, a particulate material is fed into a mixing chamber. The particulate material is agitated within the mixing chamber and conveyed to a mixing chamber outlet. A coating is directed into the mixing chamber and the flow of the coating is controlled based on the volumetric flow rate of the particulate material into the mixing chamber. The coating includes at least one compound selected from herbicides, insecticides, nutrients, wetting agents, surfactants, fungicides, biologicals, inoculants, and mixtures thereof.
    Type: Grant

  • Publication number: 20130251901
    Abstract: An apparatus and method are provided for coating a particulate material. A mixer defines a mixing chamber and receives a particulate material. An agitator includes a plurality of arms projecting radially outward from the shaft and a plurality of paddle blades positioned on the ends of the arms. The blades are formed such that the particulate material in the mixing chamber is directed in a rotational direction, a radially inward direction and an axial direction within the mixing chamber. A material feed system is provided for delivering a first coating material into the mixing chamber during rotation of the agitator, a polymer material during mixing of the coated particulate material and a reaction material for causing a reaction between the colorant feed and the polymer feed for creating an encapsulated particulate material.

  • Patent number: 7734316
    Abstract: A mobile wireless communication device, and methods therein, including producing a user-configurable sensory output (620) upon the occurrence of some event on the device, for example, the transition between sleep and active modes, or the mechanical actuation of a portion of the device. In some embodiments, the user-configurable sensory output terminates (630) after a specified time period. In other embodiments, a service provider selects the sensory output and associates it with a particular event that occurs on the device, whereupon the sensory output is produced on the device upon the occurrence of the event, for example, to communication information from the service provider.
