John Paul Wilkinson 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).

  • Rheometer control system
    Patent number: 9958368
    Abstract: A rotary rheometer is disclosed that includes improved control logic. This logic can provide continuously sampled force control logic, compliance control logic, adaptive control logic, anti-windup logic, and/or inertial correction logic.
    Type: Grant
    Filed: July 31, 2009
    Date of Patent: May 1, 2018
    Assignee: Malvern Instruments Limited
    Inventors: John Paul Wilkinson, Ian Pearson
  • Expert-system-based rheology
    Patent number: 9389159
    Abstract: A rheometer is disclosed that includes rheometry logic that is responsive to a material selection control, to an objective selection control, to material property storage, and to process parameter storage, and is operative to assist the user with a measurement using the rheometer. In another general aspect, a rheometer includes sample history storage operative to store a history that spans a plurality of different operations performed by the rheometer on a same sample.

  • Rheometer with modular environmental control system
    Patent number: 8225644
    Abstract: A rheometer uses a removable integrated environmental control cartridge that includes at least one environmental control unit, at least one supply port operative to interact with the supply port for a chassis of the rheometer. It also includes at least one mechanical alignment interface that is operative to interact with the mechanical alignment interface of the chassis to align both the mobile part with respect to the fixed part and the chassis supply port with respect to the environmental control cartridge part. In another general aspect, a rheometer can use an environmental control cartridge interface operative to report an identity of the integrated environmental control cartridge to an environmental control cartridge identification interface of its chassis.
