Granted: 1992-07-21
Abstract: BLADE-TO-BLADE VIBRATION DAMPER    ABSTRACT OF THE DISCLOSURE           A blade-to-blade vibration damper for a turbine rotor blade is disclosed.  Each blade has airfoil, platform and root portions.  A plurality of blades are circumferentially spaced about a rotor disk.      An inclined recess extends into the platform portion of each blade from a first surface thereof, and toward its root portion.  A U-shaped wire-form damping member has its in-turned marginal end portions slidably received in each recess.  When the rotor disk is rotated at a sufficient angular speed, the damping members move outwardly by the centrifugal force acting thereon to engage the opposing surface of the platform portion of the adjacent blade.  When so engaged, the members damp vibrations of such blades and seal the space between the opposing platform surfaces.

Abstract: ADHESIVE-FREE BONDING OF CONTINUOUSLY            MOVING WEBS TO FORM LAMINATE WEB              AND PRODUCTS CUT THEREFROM     ABSTRACT            Method and apparatus for ultrasonically bonding continuously moving webs to one another using a stationary vibrating horn and a relatively slick, non-thermally softenable moving slip layer interposed between the webs to be bonded and the horn to prevent web damage. Interposing the slip layer between the webs to be bonded and the ultrasonic horn improves both the quality and efficiency of web bonding. It reduces friction between the travelling webs and the substantially stationary ultrasonic horn not only due to its relatively slick surface, but also due to the compressive force which the slip layer exerts upon the webs to be bonded.          This in turn minimizes jamming and hangups in the very limited clearance existing between the rotating anvil roll and the substantially stationary vibrating ultrasonic horn. In addition, the slip layer maximizes retention of heat either generated in the laminate web by the ultrasonic horn or transferred to the laminate web structure by preheating one or more of the webs. If desired, the slip layer may be comprised of a continuous belt which rotates about the ultrasonic horn. In addition, a secondary slip layer may be provided intermediate the webs to be bonded and the rotating anvil roll to minimize heat transfer from the webs to the anvil roll and to prevent sticking of the webs to the anvil roll. In a particularly preferred embodiment the peripheral edges of the raised anvil bosses are relieved slightly to minimize web tearing and to enhance bond strength. In still another preferred embodiment the anvil roll is heated to a temperature approximating the maximum temperature achieved by the webs being bonded to minimize heat transfer from the webs to the anvil roll during the bonding operation. Novel laminate products bonded on-the-fly without the use of an ancillary adhesive may also be produced.

Abstract: To achieve desired treatment results at both sides of a material web to be calendered, the material web is initially guided through a first nip formed between yieldable elastic surfaces confronting the throughpassing material web. In the first nip there is predominantly applied a relatively high pressure to the material web. Then the material web is guided through a successively arranged second nip formed between practically non-yieldable hard surfaces confronting the throughpassing material web. In the second nip there is applied, apart from pressure, in particular heat to the material web. The treatment result achieved in the first nip, namely the smoothness and glaze values of the treated material web, are augmented at both sides of the material web to achieve desired treatment effects.
