Thomas J. ZOLPER 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: 10933390
    Abstract: A system for fabricating microparticles useful for example in managing invasive species is provided. The system provides a nozzle for atomizing liquefied droplet material which is then suspended in a cyclonic separator receiving refrigerated gas until the droplets can solidify. In this way small droplets (less than 100 ?m) can be readily fabricated in bulk without clumping and aggregating.
    Type: Grant

    Date of Patent: March 2, 2021
    Assignee: WiSys Technology Foundation, Inc.

  • Patent number: 10765102
    Abstract: The present invention provides a molluscicide application apparatus and process that disperses the molluscicide below the water's surface in a manner that minimizes air entrainment and ensures that the molluscicide solution settles at the targeted floor of the body of water, such as a river or lake bed where driessenid mussels are concentrated, and do not rise to the water's surface or disperse. The present invention also maintains a desired viscosity level, for example, 180 centistokes, at typical freshwater temperatures varying from 15° C. to 25° C. by adjusting the flow rate and/or nozzle orifice area of the molluscicide application.
    Type: Grant

  • Patent number: 9896640
    Abstract: A method of using lubricant compositions to reduce wear between two surfaces exposed to a load condition of at least 1 GPa is provided. The lubricant compositions comprise polysiloxane base oils having alkylaryl or a combination of alkyl and aryl functionality. The polysiloxane base oils may be defined according to the formula: wherein R, R?, and R? are independently selected, such that R is an alkyl group having between 1-3 carbon atoms; R? is an alkylaryl group comprising alkyl functionality with 3-12 carbon atoms and aryl functionality with 6 to 12 carbon atoms; R? is an alkyl group having between 1-3 carbon atoms or an alkylaryl group comprising alkyl functionality with 3-12 carbon atoms and aryl functionality with 6 to 12 carbon atoms; and m and n are integers, such that 8<(m+n)<500.

  • Patent number: 9765278
    Abstract: A method of using energy-efficient lubricant compositions to reduce wear between two surfaces exposed to a high shear condition is provided. The lubricant compositions comprise polysiloxane base oils having alkyl, aryl, or a combination of alkyl and aryl functionality. The polysiloxane base oils may be defined according to the formula: wherein R, and R? are independently selected, such that R is an alkyl group having between 1-3 carbon atoms; R? is an alkyl or aryl group having between 6 to 20 carbon atoms; and m and n are integers, such that 25<(m+n)<500 and the ratio of m/(m+n) is greater than 0.05 and less than 1.00.

  • Publication number: 20150307808
    Abstract: Traction fluids and a method of using such tractions fluids to increase the interface friction between two surfaces moved relative to one another is provided. The traction fluid may comprise a polysiloxane base oil corresponding to the structural formula: wherein R and R? are independently selected, such that R is an alkyl group having between 1-3 carbon atoms; R? is a cycloalkyl dicycloalkyl, or aryl group having between 5-20 carbon atoms; m is an integer; and n is an integer or 0 with 5<(m+n)<100 and 0.50<m/(m+n)<1.00.
