Inventor: TAUBER KLAUS
IPC: G02C5/00
Filed: 1988-10-07
Abstract: Known alloys used for the production of spectacle frames have the disadvantage that a considerable loss in their strength occurs in the range in which heating of the materials has taken place during welding or during brazing of the individual elements of the spectacle frame. Even subsequent heat treatment does not result, in the alloys known hitherto, in adequate strengths. In order to overcome these disadvantages, the alloy according to the invention has the following composition (in % by weight): 17 to 25% of Ni, 0.5 to 4% of Al, 18 to 29% of Zn, 0.1 to 0.5% of Mn, impurities to a maximum of 0.5% and the remainder of Cu. <IMAGE>

Title: Arrangement for the centring connection between two axially orientated parts of a manipulating system
Inventor: REINAUER JOSEF
IPC: B23B31/26
Filed: 1988-10-07
Abstract: An arrangement for the centring connection between two axially orientated parts of a manipulating system is described in which a mating receptacle is provided in one of the parts, such as, for example, in the spindle of a machine tool, for an axial mating extension of the other part, such as, for example, a tool-system module, and a clamping device serving to produce an applied pressure between essentially radial supporting surfaces of the parts to be coupled is also provided. The clamping device has an actuating rod via which, by means of a wedge mechanism, at least three cramp-like clamping claws arranged at a uniform peripheral distance from one another and extending essentially parallel to the extension can be pivoted into a groove-like recess while supported in the one part with a claw section lying radially inside the extension when the parts are brought together. In order to facilitate the joining of the parts but at the same time to ensure that the quality of the centring connection is increased, the extension is adapted to the position and/or the shape of the groove-like recess in such a way that it can be widened under the action of the clamping claws, swinging radially outwards, at predetermined sections for the approach of the mating surfaces.

Title: Measuring edge angle of liquid drops on specimen with smooth or structured surface - by moving reflection surface section along boundary between drop and material and evaluating beam geometry
Inventor: WOLFRUM WERNER
IPC: G01N13/02
Filed: 1991-02-01
Abstract: The method is for measuring the edge angle (1) of liquid drops (2) on a material specimen (3) with a smooth or structured surface. It relies on light directed at a suitable angle of incidence at the drop surface being reflected in a certain direction from only one surface point, or from a small surface section. The surface section is perpendicular to the bisector of the angle between the incident and reflected light directions and is therefore defined by the beam geometry. The source and/or receiver position is varied w.r.t. the drop to move the surface section along the boundary between the drop and material to determine the edge angle from the beam geometry. USE/ADVANTAGE - The method and arrangement enables simple, precise measurement of edge angle for evaluation of materials in the chemical industry or for research.
