Patents by Inventor Sheldon Dean Shumway

Sheldon Dean Shumway 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: 11794193
    Abstract: A system to measure and control real-time parameters of a mill for grinding particulate without using auxiliary energy is disclosed. Sensors connected to the mill produce signals. A signal transmitting and receiving module is connected to the sensors and receives and transmits the mill process signals to a network. A modular power generator unit powers the system. A radio antenna receives and transmits signals from and to the signal transmitting and receiving module. A master controller connects to the network and to a distributed control system to receive and use process variables and the signals to compute and transmit setpoints to the distributed control system. The system alarms for upsets conditions, alters mill control variables, or both.

  • Patent number: 10399089
    Abstract: A system to control in real time a charge volume of an autogenous mill or a semi-autogenous mill including at least one accelerometer connected to a rotatable mill shell producing acceleration over time signals. The system includes a wireless antenna, a signal receiver module, and a modular magnetic power generator unit communicating with a master control processor connected to a network and to a distributed control system of the mill. The system has computer instructions to receive the acceleration over time signals and compare the acceleration over time signals to preset charge limits and produce commands to the distributed control system to automatically alter at least one of: speed of the rotatable mill shell, a particulate feed rate, a water feed rate, and combinations thereof when compared acceleration over time signals exceed or fall below preset charge limits.
