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.
Abstract:
A fiber optic connector includes a ferrule having a mating end and an insertion end and a ferrule holder having a first end portion in which the ferrule is received and a second end portion opposite the first end portion. The first end portion defines a first bore having a first bore width for receiving the ferrule. Additionally, the first end portion defines a bore surface and at least one groove formed in the bore surface. The at least one groove extends from where the insertion end of the ferrule is located within the first bore to a front face of the ferrule holder. Ridges are formed around the first bore because the at least one groove also extends in a circumferential direction. The ridges contact the ferrule and are deflected by the ferrule in a direction toward the insertion end of the ferrule.
Abstract:
An adhesive bolt for forming a fastening point to a workpiece has a head and a shank connected to the head. The shank is set up to be introduced into a cutout on the workpiece. An adhesive is situated in the region of the shank and the workpiece. The shank is configured to enter into a non-positive preliminary connection with a bounding face of the cutout until the adhesive has hardened.
Abstract:
The invention relates to an edge trim for pieces of furniture, comprising a meltable film. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable film contains both polar and non-polar parts.
Abstract:
Endoprosthesis assemblies and methods of making endoprosthesis assemblies are disclosed. For example, endoprosthesis assemblies are described that include an endoprosthesis body and a polymeric coating about the endoprosthesis body. The polymeric coatings are engaged tightly to the endoprosthesis wall through engageable features created on the surface of the polymeric coatings and the surface of the endoprosthesis wall prior to engaging the surfaces.

Abstract:
An e-vapor device may include a vaporizer assembly that is detachably coupled to a battery assembly via a connector. The connector may include a male connecting portion and a female connecting portion. The male connecting portion may include mating arms extending from a rim of the male connecting portion. The female connecting portion may include an inner surface and lugs on the inner surface. The mating arms of the male connecting portion are configured to engage the lugs of the female connecting portion so as to electrically couple the vaporizer assembly and the battery assembly. A knurled pattern may also be provided on an outer surface of the male connecting portion and/or female connecting portion so as to conformally interface with a reversed pattern on an inner surface of the vaporizer assembly and/or the battery assembly.
Abstract:
A method can be used for joining workpieces using a fastener. The fastener includes a first head and a shank extending from the first head along a fastener axis. The joining method includes the following steps: (a) rotating a fastener about a fastener axis; (b) moving the fastener toward the first and second workpieces while the fastener rotates about the fastener axis such that the fastener increases the temperature in the first and second workpieces in order to soften and pierce the first and second workpieces along the fastener axis; and (c) advancing the fastener through the first and second workpieces and toward an open cavity of a die after piercing the first and second workpieces while the fastener rotates about the fastener axis such that the shank is partially disposed inside the open cavity in order to form a second head.
Abstract:
A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.
Abstract:
[PROBLEMS] To bond a paper sheet containing no thermally fusible component with sufficient strength without forming a through hole, deteriorating texture and increasing the material cost.[MEANS FOR SOLVING PROBLEMS] While pressing a second paper sheet (11) containing no thermally fusible component against a first paper sheet (10) containing no thermally fusible component, an ultrasonic wave is applied to the press contact portion so that fibers of the second paper sheet (11) enter mechanically between fibers of the first paper sheet (10) thus forming a bonding portion without requiring thermal fusion.
