  • Publication number: 20190315110
    Abstract: A method and installation for joining a cover layer to an object in a continuous process. Joining is effected with the aid of a joining material having thermoplastic properties, wherein the joining material is arranged between the cover layer and the object and is liquefied using ultrasonic vibration energy. Before application of the ultrasonic vibration energy, the joining material is preheated in a contactless manner with the aid of electromagnetic induction in the region of the glass transition temperature of the joining material or above this glass transition temperature. The object is in particular a chip board and the cover layer an edge strip to be joined to an edge of the chip board.

  • Patent number: 10427359
    Abstract: A joining element has an anchoring portion for in-depth anchoring in the object and a head portion arranged proximally of the anchoring portion with respect to an insertion axis. The head portion has a lateral outer surface that has a structure that is well-defined, especially within tight tolerances. The joining element is positioned relative to an object of a non-liquefiable material such that the anchoring portion reaches into an opening of the object or is placed adjacent a mouth thereof. Then, the joining element is pressed towards a distal direction, to press the anchoring portion into the opening, while mechanical vibration energy is coupled into the joining element by a tool, in an amount and for a time sufficient for liquefaction of a portion of the thermoplastic material to cause interpenetration of the thermoplastic material into structures of the object.

  • Patent number: 10406757
    Abstract: A first object is anchored in a second object. The first object has a material with thermoplastic properties, and the second material has a material that is solid and is penetrable by the first material when in a liquefied state. The second object has an insertion face with an opening having a mouth in the insertion face, and the first object has an insert portion that for anchoring is placed in the opening or about the mouth thereof. For anchoring, energy suitable for liquefaction of the first material impinges in an amount and for a time sufficient for at least partial liquefaction of the first material and interpenetration of the first and second materials. The second object, around the opening, has an anisotropic strength with respect to forces perpendicular to the opening axis.

  • Patent number: 10337543
    Abstract: An adaptor is secured to a first object. The adaptor includes an anchoring part and an adjustment part. The anchoring part includes a distally facing anchoring surface and a proximally facing first control surface. The adjustment part has a distally facing second control surface positioned to abut against the first control surface. The first control surface or the second control surface or both is/are helical. Thereby a relative z position of the adjustment part with respect to the anchoring part is defined by the relative orientation of the adjustment part with respect to the common axis while the second control surface abuts against the first control surface. This is used to adjust the z position of the adjustment part relative to the first object, in connection with the orientation of the adjustment part being defined and possibly fixed by the function of the adaptor/the adjustment part.

  • Publication number: 20180304543
    Abstract: A method of mechanically securing a first object including a thermoplastic material in a solid state to a second object with a generally flat sheet portion, with a perforation of the sheet portion, and with the sheet portion having an edge along the perforation is provided, wherein the first object is positioned relative to the second object so that the edge is in contact with the thermoplastic material and wherein mechanical vibration energy is coupled into the assembly including the first and second objects until a flow portion of the thermoplastic material due to friction heat generated between the edge and the thermoplastic material becomes flowable and flows around the edge to at least partially embed the edge in the thermoplastic material. After the mechanical vibration stops, the thermoplastic material is caused to re-solidify, whereby the re-solidified thermoplastic material at least partially embedding the edge anchors the first object in the second object.

  • Patent number: 9931165
    Abstract: A light diffuser, which is particularly suitable for introducing diffuse light into a tissue, is produced by interpenetration of a diffuser material in a liquid state into a boundary layer of a porous shaping material, by which process a diffuser surface is formed having a surface structure which represents essentially a negative of the pore structure of the shaping material and includes undercut structures induced by a surface tension. The light diffuser is e.g. produced by introducing a diffuser blank including material that is liquefiable through mechanical vibration into the shaping material and simultaneously stimulating it with mechanical vibrations, such that the liquefiable material liquefies at least there where it is in contact with the shaping material and is pressed into the shaping material. An in situ production of the diffuser is particularly advantageous for photodynamic therapy in bone tissue.

  • Patent number: 9924988
    Abstract: A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

  • Patent number: 9888939
    Abstract: A punching device for preparing a recess in a bone has a punching tool usable for such a punching device. An implant usable with the punching tool is provided and a method for preparing a recess in a bone are disclosed. The punching device comprises an ultrasonic sonotrode and a punching tool which is fixable to the sonotrode at its proximal extremity. At its distal extremity, the punching tool has a thin-walled portion having a non-rotational symmetric cross-section. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. Subsequently, an implant can be held in such recess. Due to its lack of rotational symmetry, the implant may absorb rotational forces around its longitudinal axis.
