Abstract: An apparatus for optically inspecting a test specimen has an at least partly reflective surface including a camera having a number of pixels and an illumination device having a multiplicity of spatially distributed light sources. A workpiece receptacle serves for positioning the test specimen relative to the illumination device and the camera, such that light from the light sources is reflected by the surface to the camera. An evaluation and control unit generates a series of different illumination patterns on the surface, wherein in the course of the series different light sources are switched on. An individual light origin region is determined on the basis of the images recorded by the camera for at least one pixel, whereby the region represents a spatial distribution of individual light contributions generated by the light sources via the surface on the at least one pixel.

Abstract: An optoelectronic measuring method and a distance measuring device for carrying out the method for determining the dimensions with respect to length, width or height of objects mounted in or outside of processing or measuring machines. At least one ray bundle transmitted by a measuring head of a measuring device is projected on a surface of an object to be measured as a dot-shaped measuring spot at various locations on a circumferential line of a geometric figure, and the reflected ray bundle projects through a projection unit the respective measuring spot onto an optoelectronic transducer unit of the measuring head and the signals produced by the transducer unit are evaluated in an evaluating unit.

Abstract: The invention relates to a method for detecting measurement data on coordinate measuring and digitalizing machines. When the measuring times of the coordinate measuring machine and the sensor are determined by an electric signal (trigger), the equality thereof can be guaranteed and the influence of signal propagation delays can be excluded. The nth sensor information always corresponds to the nth machine information. Allocation is made easier when each value detected at a measuring time obtains an identifier. In one embodiment, surface points of a free forming surface can be detected during movement of the sensor on the coordinate measuring machine and by means of a measuring sensor. The measuring times are determined by an electric signal that is produced by the sensor and is transmitted to the coordinate measuring machine. The signal triggers distance measuring of the sensor as well as the output of the current machine position.

Abstract: The invention relates to a method for detecting measurement data on coordinate measuring and digitalizing machines. Usually, the position of the machine, e.g. the x-, y-, z-coordinate, has to be linked to a value, e.g. distance value, that is generated by calipers or a sensor for obtaining the space coordinates of a surface point during detection of geometries on a coordinate measuring machine or digitalizing machine. It has to be guaranteed that the information of the coordinate measuring machine and the sensor originate from the same measuring time, whereby said information has to be linked, when a measuring sensor is used for detecting the geometry of an object, e.g. a free forming surface, and when said sensor is moved during detection. When the measuring times of the coordinate measuring machine and the sensor are determined by an electric signal (trigger), the equality thereof can be guaranteed and the influence of signal propagation delays can be excluded.

Abstract: A profile member of hybrid composite materials including alternating layers of metal and fiber-reinforced composite is fabricated by three successive steps. In a first step, wet composite prepreg layers impregnated with a binder are alternately stacked with metal layers, so that the uncured binder wets the surfaces of the metal layers. Next, the initial uncured layer structure is plastically deformed using successive pressure or bending deformation steps until a prescribed cross-sectional contour of the layer structure is achieved. Finally, the formed layer structure is supported and fixed in an autoclave, in which the binder is cured under an applied mechanical pressure and elevated temperature, to form the finished profile member.

Abstract: The invention is directed to a method and an apparatus for measuring the edges 13 of a workpiece 5 with an optical probe 4. The probe 4 measures the distance values (a) between the probe 4 and an adjustable scanning point 15. In the method, the scanning point 15 is moved along a loop path (36a, 36b, . . . , 36n) over the edge 13 of the workpiece 5 to be measured in order to obtain more exact values for measured points of the edge at a higher measuring speed. During the method, distance values (a) are measured by the probe 4 and a point P of the edge 13 is determined from the course of the measured values.

Abstract: In the case of a printing cylinder for a printing plate made of a magnetizable material, a roller-shaped basic body is provided which, on its circumference, has an axial slot for the hanging-in of a bent edge of the start of the printing plate and several holding magnets distributed along the circumference, one wall of the slot being formed of a strip made of a magnetizable material which, inside the slot, is provided with holding magnets used for holding the bent edge of the printing plate.

Abstract: This disclosure relates to a method and an apparatus for producing a punch (3) having sharp cutting edges (41) for label cutting apparatus or the like. In order that the cutting edges (41) may have a constant height and that they may be made semiautomatically, a punch body (3) is provided with a raised edge (4) in a first process step, by etching for example, and this edge is then made into a sharp cutting edge (21) in a second process step by hammering. An apparatus suitable for this purpose contains a table (2) for the punch body (3), over which tool (32, 70) in the form of a hammering and/or cutting tool and having an roof-shaped notch (34) is disposed, which can be reciprocated automatically in the direction of the table (2) between two dead centers in order to give the raised edge (4) an external contor corresponding to the roof-shaped contour of the notch (34).

Abstract: The drying medium (T) is driven through the adsorbent (5) of the adsorption cell (1) in the same direction as the process medium (P). Initially it is ejected through an auxiliary output (19) and a device (26) for removal of dampness and then is changed-over towards a main output (18) and preferably into the workroom (A).
