  • Real time mottle measuring device and method
    Patent number: 4966455
    Abstract: Devices and methods for measuring mottle of paper-like materials are provided. the invention includes directing a radiation over a paper-like material and scanning it in a plurality of directions. Radiation scattered by the paper-like material is detected to produce an output. This output is processed to provide a reading proportional to the mottle of the paper-like material. The invention uses electro-optical devices and signal processing to quantify mottle as an appearance property. Gloss measurements of the paper-like material can also be quantified and simultaneously displayed.

  • Laser induced acoustic generation for sonic modulus
    Patent number: 4674332
    Abstract: A method and device which measures the velocity of ultrasonic waves in a moving web is disclosed. The excitation source is a laser or other device which produces short intense light pulses and the detection system is either a peizoelectric transducer or a microphone. The latter obviates any need for physical contact with the web in order to carry out tests for strength parameters as the web is manufactured.
