Abstract: An ultrasonic metal welding device for welding electrical conductors using a compression chamber that is adjustable at least n height and that is delimited on opposite sides by a section of a sonotrode as a first delimiting surface and by at least one section of a counter electrode (156) as a second delimiting surface, wherein for welding, the counter electrode and the sonotrode are displaced relative to one another. The counter electrode used is one that comprises sections (152, 154) of geometrically different working surfaces or is composed of at least two sections that are displaceable relative to one another.

Abstract: The invention relates to a method for producing a positioning element for fixing a drilling template on a gingiva of a patient's jaw in a position relative to a jawbone of the jaw. The positioning element is configured to fix the drilling template, by means of pressure, which the patient applies to the positioning element by closing the jaw and an opposing jaw, in the position for making implant holes in the jaw for dental implants.

Abstract: A device for welding rod-shaped electrical conductors and a sonotrode for such includes a compression space for receiving two connection regions of the conductors to be connected, said connection regions extending in a first axial direction (x-axis), the compression space being defined by a working surface of a sonotrode, which transmits ultrasonic vibrations, and a counterface of an anvil at two opposite sides in a second axial direction (z-axis) and by a boundary surface of a slider element, displaceable in the second axial direction (z-axis), and a boundary surface of a boundary element on two opposite sides in a third axial direction (y-axis). In a special contact zone, which is a section of the working surface of the sonotrode and serves to subject at least one connection region to ultrasonic vibrations, the working surface has a surface configuration that differs from a contact zone formed by the remaining working surface.

Abstract: The invention relates to a device and to a method for producing a tested weld joint between two contact elements (11, 12), which are joined together in a welding plane S, comprising a compressing space for accommodating the contact elements (11, 12), said compressing space being delimited by a work surface of a sonotrode, which transmits ultrasonic oscillations, and a counter-surface (15) of a counter-electrode (16) in a first axial direction at two opposing sides and by delimiting surfaces of opposing delimiting elements in a second axial direction at two opposing sides, said device comprising a test head (27) next to the compressing space, and said test head being able to be transferred from a position outside of the compressing space to a position within the compressing space in such a manner that the test head (27) is disposed within the open compressing space in a test mode of the device for subjecting a contact element (12) of the previously produced weld joint to a shear force essentially oriented para

Abstract: The invention relates to a drill template for drilling an implant hole for a dental implant, the drill template having a through-opening and at least one aperture, wherein the drill template is provided or can be placed for resting or bearing against a jaw, palate and/or one or more teeth and is at least partially adapted to the geometry of the jaw, palate and/or one or more teeth, wherein the through-opening is provided for guiding a drill, in particular a dental implant drill, and/or for inserting a guide sleeve for a drill, and wherein the aperture is provided for conducting a fluid, wherein the drill template comprises a fluid-conducting element.
