  • Patent number: 10363077
    Abstract: A perforated sheath is anchored in a tissue opening with the aid of a tool, wherein the anchorage is achieved with the aid of mechanical vibration and a material which is liquefiable by the vibration. The tool includes a vibrating element and a counter element. Distal portions of both elements are introduced into the sheath to be in contact with each other at an interface. The vibrating element is connected to a vibration source and the vibrating element and the counter element are held against each other for effecting liquefaction of the liquefiable material at the interface. Under the effect of the force applied to the vibrating and counter element for holding them against each other, the liquefied material flows from the interface through the sheath perforation and penetrates the tissue.

    Abstract: A sonotrode and anvil are adapted for ultrasonic welding of work pieces, to produce a narrower weld region that exhibits greater durability, permitting use of less material per package. The horn-to-anvil contact is through a plurality of energy directors arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors include a series of plateau surfaces regularly spaced apart in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The energy directors of the horn are configured to interlock with the energy directors of the anvil. The rectangular-shaped plateaus are spaced apart by angled side-surfaces that form valleys. A stepped transition to a corresponding region of reduced height for the energy directors of the sonotrode and anvil may form a cosmetic seal region with a lesser integrity, in addition to the main barrier seal.

  • Patent number: 8905291
    Abstract: Selected surface regions of coulomb vibration damping strips are bonded face-to-face by ultrasonic welding to a surface region of an article that may experience excessive vibration in use. In one embodiment, prior to welding, the intended facing side of the damping strip is treated to form surface regions that are oxidized, roughened, or coating so that the treated regions do not weld to the article surface. In another embodiment of the invention the ultrasonic welding process is controlled so as to produce regions (sometimes randomly interposed regions) of welded and non-welded regions between the damping strip and adjacent article surface. The unbonded regions of the otherwise welded strip lie in closely-spaced, interfacial, frictional contact with the adjacent article surface to damp vibration in the article.

  • Publication number: 20140338814
    Abstract: A vibration welding system and method having an operating vibration frequency of 260 Hz or higher. A pressing action between two workpieces is effected by directly controlling, with a control system and a sensor, the relative positions of the workpieces during some or all of the weld cycle, or by controlling the speed between the workpieces during some phase of the weld cycle and controlling the force between the workpieces during other phases. An external control device can be coupled to a control system, to produce an input signal to adjust the speed of relative motion between the workpieces, the force therebetween, or both speed and force based on the input signal.

  • Publication number: 20140338841
    Abstract: The linear friction welding (LFW) apparatus of this invention, in various embodiments includes a vibrating assembly or assemblies, which simultaneously vibrates both work pieces along the weld axis during the weld process. In one embodiment, separate vibrating assemblies are used to vibrate each work piece along the weld axis relative to each other. Each vibrating assembly has its own oscillator mechanism with motors and cams that can be moved into and out of phase with that of the other vibrating mechanism to generate the relative movement between the work pieces. In another embodiment, the apparatus includes a vibrating assembly that uses a single oscillator and two sets of rocker arms supporting carriages operatively connected by a linkage mechanism to simultaneously vibrate both work pieces along the weld axis.

  • Patent number: 8858742
    Abstract: A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host device, a check station, and a robot. The robot moves the horn and anvil via an arm to the check station. Sensors, e.g., temperature sensors, are positioned with respect to the welding equipment. Additional sensors are positioned with respect to the check station, including a pressure-sensitive array. The host device, which monitors a condition of the welding equipment, measures signals via the sensors positioned with respect to the welding equipment when the horn is actively forming a weld. The robot moves the horn and anvil to the check station, activates the check station sensors at the check station, and determines a condition of the welding equipment by processing the received signals. Acoustic, force, temperature, displacement, amplitude, and/or attitude/gyroscopic sensors may be used.
