Richard Hartel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11529307
    Abstract: Colorant particles made from an insoluble protein-based substrate to which a dye is adsorbed are disclosed. The colorant particles are highly dispersible onto solid surfaces or within liquid systems, and thus can be used as substitutes for the alumina-based lake particles that are conventionally used as colorants in consumer products, such as food or beverage products, cosmetic products, pharmaceutical products, nutraceutical products, or toys.
    Type: Grant

    Date of Patent: December 20, 2022
    Assignee: Wisconsin Alumni Research Foundation

  • Publication number: 20060128953
    Abstract: A method is provided for making large, uniform and individual crystals from aqueous solutions including the steps of obtaining a concentrated aqueous solution by means of evaporation; rapidly cooling the solution from a post-evaporation high temperature to a first lower temperature, wherein the first lower temperature is lower than the post-evaporation high temperature and further wherein the first lower temperature is an isothermal crystallization temperature of said solution; generating a batch of initial nuclei by inducing nucleation at the first lower temperature and starting crystal growth; uniformly spreading the initial nuclei into a bulk solution; maintaining simultaneous and rapid growth of crystals from the nuclei at the first lower temperature for a predetermined length of time; continuing the growth of the crystals to produce large, uniform and individual crystals for a predetermined length of time at a temperature that varies gradually from between a first lower temperature to a second lower temp
