    Abstract: An apparatus for testing stiffness characteristics such as modulus of elasticity E of an article such as a piece of lumber moving in a conveying direction transverse to the testing axis, comprises a bearing unit capable of contacting the piece of lumber at two spaced apart portions thereof. There is provided a first deflecting unit including a first working element being normally disposed in a first static position relative to the conveying path for applying a first thrust against a loaded area on the article at an intermediary portion thereof located between the spaced apart portions, to produce an article deflection of a first magnitude. Each working element defines a loading surface extending substantially parallel to the article-conveying path. There is further provided a second deflecting unit including a second working element being normally disposed in a second static position relative to the conveying path for applying a second thrust against a loaded area of the article intermediary portion, to produce an article deflection of a second magnitude, wherein the second position differs from the first position relative to the conveying path by a differential value. The apparatus further comprises load cells coupled to the bearing unit for generating signals indicative of respective magnitudes the first and second thrusts as applied by first and second deflecting units, and a computer for deriving from such signals and differential value an indication of the stiffness of the article, such as modulus of elasticity E.

    Abstract: A method and apparatus for measuring substrate bending stiffness and thereby basis weight on a real time basis. Provided is a corrugator having a plurality of parallel ribs, with one or more sheets of the substrate provided below the corrugator wherein a predetermined gap exists between a topmost sheet of the sheets and the corrugator. A vacuum is applied between the corrugator and the topmost sheet, wherein the vacuum is sufficiently large to raise the topmost sheet, thereby deflecting and bending it into a profile corresponding to the arrangement and size of the corrugator ribs and bending stiffness of the substrate. One or more sensors are provided for measuring the deflection of the topmost sheet. The vacuum, an air knife output and/or a fluffer output are then adjusted according to predetermined rules and the measured deflection.

    Abstract: A fatigue testing system subjects a test specimen to a rotary stress applied about an axis at one or both ends which is perpendicular to the axis of the test specimen. The stress applied may be selected from sinusoidal, random, impulse or a signal generated by the stresses applied to an actual in service specimen. A servo applies the stress to the test specimen through a coupler and the changes in the electrical resistance of a portion of the test specimen is sensed to detect the initiation and propagation of a stress failure.

    Abstract: A method, technique, and apparatus proof test an optical fiber interconnect by applying an ends off-set stress on the optical fiber until the optical fiber fails or breaks, either immediately (short-term strength), or as a result of the delayed-fracture/"static-fatigue" phenomenon for the given off-set, and, hence, for the given stress (long-term strength), imposed for the measured period of time. If, for instance, the short-term strength is addressed, the off-set is measured at the time of the failure, and the corresponding critical strain of the optical fiber is then predicted. In predicting the critical strain, the method and apparatus iteratively determine the total strain, including non-linear components thereof, for an optical fiber interconnect experiencing the measured ends off-set. The analytical model/method includes the steps of iteratively processing characteristic parameters associated with the optical fiber, and determining the non-linear strain associated with the optical fiber. The apparatus includes a processor for implementing the disclosed method.
