Anticaking Patents (Class 71/64.12)
  • Patent number: 11534367
    Abstract: An irrigation system for use with a spa includes a water heating circuit, an automatic water fill valve connected to a water source, and an irrigation pump in fluid communication with the spa through a first irrigation line and electrically connected to a power source through a switch arrangement. The irrigation pump is adapted to pump water to at least one irrigation head. The automatic water fill valve then refills the spa from the water source. The system may include a fertilizer injector, a skin-product injector, a water softener, and various sensors running through an irrigation application on a smart phone to control the irrigation system and operation of the spa.

  • Patent number: 8419820
    Abstract: Improved, solid water-soluble fertilizer (WSF) compositions are presented which comprise at least one acid (optionally nutritive) and at least one basic fertilizer component. In one or more embodiments of the present invention, the WSF compositions demonstrate improved solubility of one or more nutrients or additives in solution, do not require additional dissolution aids or anti-caking agents, demonstrate fast dissolution times, produce precipitate free solutions, are readily compounded without intermediate wetting or drying steps, do not generate gas, and demonstrate improved stability under typical usage conditions. Finally, the WSF compositions may be used in improved processes for the creation of stock solutions, optionally with cold water, and/or delivery of nutrients to plants.

  • Patent number: 8343891
    Abstract: A method of improving the properties of urea granulates, more especially the caking tendency, the dust formation and the foaming tendency in aqueous media, by the addition of an additive to the urea, wherein the additive comprises a carboxylic acid compound with the general formula XY—(Z)—COOH, in which Z is a saturated or unsaturated hydrocarbon with 1-25 carbon atoms and X and Y are selected from the group consisting of a hydrogen atom or a polar organic functional group, and in that the additive is added as a solution in a polar solvent to the urea granulates, which are subsequently dried.
