Latest Patents

One of Dennis A. White's latest patents focuses on the detection of delamination of rubber covers from metal substrates. This innovative method involves testing the bonding of an elastomeric cover to a metal roll by transmitting audible frequency waves through the compliant roll cover. The waves are received by a transducer mounted to the underlying steel roll, allowing technicians to analyze the resulting signal by listening to the audio frequencies transmitted. The elastomeric material, such as rubber, does not transmit sound effectively, while sound travels quickly through steel with minimal attenuation. This method enables the detection of any failure or significant variation in the roll/cover bond by analyzing the quality of sound transmitted through the rubber-steel interface.

Another significant patent by White is an ultrasonic inspection method. In this method, radially spaced calibration holes are drilled parallel to the exterior surface of a cylindrical shell for a dryer roll. An ultrasonic transducer is mounted in a fixture filled with a coupling medium, allowing for adjustment of the spacing and angle of the transducer as it traverses the shell during rotation. The transducer produces a signal directed to the shell, and a computer calculates the time the signal takes to travel from and return to the transducer, determining the depth of the shell from which the signal returns. This method allows for the detection of clear signals corresponding to holes up to one inch from the surface by adjusting the ultrasonic transmission angle.
