Patents by Inventor Roy C. Hauser

Roy C. Hauser 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).

  • Device for placing a charge on an object and a method of retrofitting a conveyor for the device
    Patent number: 6728090
    Abstract: A device places a charge on an object passing by and proximate to the device in a first direction along a transport axis. The device includes a body having a surface. A power input is disposed in the body. A plurality of resistors each have a longitudinal resistor axis and each are capable of receiving power from the power input. Each of the plurality of resistors is disposed in the body with the longitudinal resistor axis being generally parallel to the surface. An ionizing pin is electrically connected to each of the plurality of resistors for receiving power to generate ions. The object is charged by passing the object by and proximate to the surface of the body in the first direction to receive ions generated by the plurality of ionizing pins. The device provides a relatively long object dwell time, thereby increasing the amount of time that the area of the object is exposed to an ion stream from the device.
