Abstract: A deckle-edge-simulating apparatus generally comprising a conveyor system (22-32) for transporting a web of paper through the apparatus, and a novel deckle-edge-simulating assembly (10) operatively associated with the conveyor system. The deckle-edge-simulating assembly generally includes a configured transport roller (66) or anvil in association with a deckling fixture (71, 80). The anvil is disposed beneath the web of paper, and includes one or more circumferential grooves (85) in its surface. The deckling fixture includes a blunt-edged blade (80) extending from and between a pair of nip forming rollers disposed on either side of the blade, and into one of the grooves of the anvil. As the web of paper passes across the anvil, the blunt-edged blade operates to burst the fibers of the paper to create a simulated deckled edge. The nip forming rollers serve to firmly hold the web of paper in position during this deckling procedure.

Abstract: Planing vessels of improved performance capability and methods for improving such performance and foils which may be associated with a planing vessels for providing improved performance capability. A dynamic downward force generated as the vessel (1) moves through water, preferably by a foil (3), is imposed on the vessel, with the locus of the force positioned, in the transverse direction, at the longitudinal vertical centerline plane of the vessel. In the longitudinal direction the locus of the dynamic force is positioned, relative to the other forces acting fore-to-aft on the vessel, to decrease the trim angle of the vessel, desirably to less than two degrees. Vessel wetted surface configurations are provided for stable and efficient operation at low trim angles, including the following. A deep draft, fine entrance (32) which minimizes rise at the bow experienced with conventional planing vessels and assists in maintaining laminarity of flow at the planing surfaces. A foil (31) extending along the bowpeak below the waterline and spaced forwardly thereof streamline the flow passing the bow to thereby decrease spray and turbulence. A skeg (32) extending downward at the bottom of the hull at the entrance along the longitudinal centerline plane which improves directional stability and also assists in maintaining flow laminarity. A sweptback wing located at the entrance, preferably mounted at the lower margin of the skeg positioned with an angle of attack which generates an upward force to improve the vessel stability against pitch and yaw in disturbed water. An aftmidships planing floor (11) having a rise from midships to the stern trailing edge desirably from 50% to 100% of the midships draft improves the stability of the vessel when operated at trim. A release floor (21) extending aftward 5 to 25% of the waterline length of the vessel, preferably from a transverse step (4), and rising over this length 10 to 50% of the midships draft to a transverse trailing edge (22). The trailing edge and the release floor, in the transverse direction, are parallel with base plane of the vessel. The pressure release floor reduces the pressure on the aftward flow to separation at the trailing edge in a gradual and uniform manner which reduces drag. Chine lines (12) at the margins of the aft planing floor are provided with fins which extend aftwardly and upwardly of the stern trailing edge to effect a smooth flow separation. The foil to generate a downward force in the flow desirably is positioned below the stern trailing edge and contoured to produce minimum induced drag and to divert the flow at its trailing edge downwardly so as to reduce turbulence and drag at the stern.

Abstract: A method and apparatus for monitoring the structural acoustic signature of a structural member in response to a transient load, corresponding to detected vibration frequencies transmitted by the structural member including the fundamental and harmonic frequencies of the structural member, to determine changes in structural integrity and to determine the nature and type of transient loads. The structural acoustic signature of the structural member in a first condition in response to a first transient load is compared to a structural acoustic signature from a second transient load whereby differences in the signatures correspond to the occurrence of changes in the elastic qualities or condition of the structural member. The signatures are preferably evaluated in the frequency domain. The nature and type of transient load can be deter­mined by evaluating the waveform shape of B struc­tural member in response to the unknown load against a history of waveform shapes corresponding to known loads. A plurality of remote structural members such as highway bridges may be monitored by a central station.
