The invention relates to a round dental blank holding ring, in particular having a holding projection () forming an undercut, wherein the holding ring () consists of at least two components (), the harder one of which overlaps the softer one.

Round dental blank holding ring and an arrangement having a blank and a holding ring

A blank holder and a blank are provided, the blank holder having a receiving area for a substantially disc-shaped blank, the receiving area being curved. The receiving area forms a straight, circular or part-circular or arc-shaped form-fitting profile. The blank has a matching guide shell which can be inserted or turned into the form-fitting profile.

Blank holder and blank

The invention relates to a clamping device () for a tool () on a machine tool having a holder block () with at least 2, in particular a multiplicity of, apertures () for receiving clamping sleeves (), wherein at least two clamping sleeves () are received in the apertures (). Each clamping sleeve () has a clamping element (), with which a tool (), in particular a shaft () of a tool (), can be clamped. The clamping sleeve () at least partially passes through in each case the aperture () in the holder block () and has, at its end opposite the clamping element (), the rear end, an expansion element () which engages behind the holder block () or a counter-support element () of the holder block ().

Clamping device for a tool on a machine tool

A lightweight construction fastener or clip having a clip body and a fastening element. The clip body includes a first leg and a second leg, which are connected with each other by a webat one end. The clip body is formed of one piece, but includes at least two volume sections, wherein the first sectionis formed of a first plastic and the second volume sectionis formed of a second plastic. The properties of the first and second plastics are different from each other with respect to one or more criteria. A method for producing such a clip body includes manufacturing it in one piece in a multi-component injection molding process from at least two plastics. Further the invention includes a method for manufacturing the lightweight construction fastener or clip by placing a fastening elementinto the injection molding tool; encapsulating the fastening elementand overmolding the fastening elementin a multi-component injection molding process.

2-component clip

The invention relates to a ball screw () with a threaded spindle (), a nut (), rolling bodies () and at least one deflecting device (), wherein the threaded spindle () is displaceable by rotation, and wherein the deflecting device comprises an inner first body part () and an outer second body part (), which body parts together form a deflecting channel (), wherein the deflecting channel () has two tubular ends () which are connected to each other via a transfer region (), wherein the tubular ends () of the deflecting channel are in each case formed by mutually complementary partial tubular sections () of the body parts (), and wherein a sleeve () surrounding the nut () is provided, the deflecting device () sits in an opening () in the nut (), the deflecting device () projects radially beyond the outer lateral surface of the nut () in a relaxed state when the sleeve () is absent and, in the presence of the sleeve (), said sleeve exerts a radially inwardly directed force on the deflecting device ().

Ball screw

An attachment receptacle () which can be fixed on a head covering, such as a helmet, of a user and has a clamping device is provided. The attachment receptacleis fixed by means of a fixing component, for example having hook-like retaining brackets, on the back of a head covering and is connected via a clamping element to the front or to a sighting device mounted on the front, such as a night vision device. The attachment receptaclewith the clamping device is formed in such a way that externally accessible components are integrated in the form of the receptacle, in such a way that no projecting or protruding components can cause unintentional actuation of the clamping device. The attachment receptacleis furthermore advantageously formed on the head covering so as to be adjustable in height.
