摘要： A blank for producing a formed dental part has closely toleranced reference faces being arranged at one end of a blank member lying opposite a retainer projection. The reference faces comprise two surfaces lying opposite one another that have a defined spacing from one another with close tolerances. The surfaces are advantageously formed by a reference part with a cylindrical cross section that is secured onto the blank member.

摘要： A dental x-ray diagnostics installation for producing panorama tomograms of the jaw of a patient has clocked CCD sensors which generate electrical signals proportional to the radiation intensity thereon, and which are operated at a speed to simulate a moving x-ray film. For the purpose of simultaneously acquiring exposures of a number of different jaw slices at different depths of field during one exposure, at least some of the CCD columns are driven with different clock frequencies by separate clock inputs.

摘要： The invention relates to a measuring device and a method based on a confocal microscopy principle. The inventive device comprises a light source (1), a diaphragm unit (3) for limiting a beam, an imagine optical system (4) for focusing the light (5) which is irradiated by said source on a measurable object (6) and passes through said diaphragm unit. Said device also comprises an optical system (10) for receiving the light (5) reflected from the object and passing through said optical system or another diaphragm unit disposed in an observation beam (7) and an image receiver (10) which is provided with at least two radiation-sensitive sensor elements (13, 14) (pixel). Said invention is characterized in that, in order to obtain the image of an altitude information-containing measurement, the device is also provided with means (11) for modifying the beam optical path length disposed between the light source (1) and/or the image receiver (10), on one side, and the object (6) on the other and the optical distance (d) of a focal point is modifiable in a predetermined manner. In addition, said intention makes it possible to influence the dependence of an accumulation of charges (Q13, Q14) in at least two sensor elements (13, 14) on the light intensity of the observation beam (7) during the exposure time in such a way that a correlation associated with the optical distance (d) of an image plane can be carried out by the imagine optical system (4), thereby making it possible to reconstitute the altitude co-ordinate (zs) of the object by distributing the intensity values obtained during the exposure time from at least two sensor elements (13, 14).

摘要： The invention relates to a method for producing a dental prosthesis element (7), according to which the dental prosthesis element (7) is manually reworked. Construction data (17, 17′, 17″) relating to the dental prosthesis element to be produced is recorded together with measurement data (7′) relating to the dental prosthesis element (7) to be produced and is reproduced on a display (4), the measurement data having been recorded by means of a three-dimensional measurement device (2). The invention also relates to one such method whereby a 3D data record of the tooth situation (14) is reproduced on the display (4) instead of the construction data. The invention further relates to a device for the partial manual treatment of the dental prosthesis element. Said device comprises a three-dimensional measurement device (2), a display (4), and a computer unit (3) comprising means for the correlation and comparison of two data records and for graphically presenting the data generated by the comparison.

摘要： A method for detecting and representing one or more objects, such as teeth, their preparations and their immediate environment, using a camera. A first recording is made wherein a still image is produced. The still image is blended into a current, mobile search image in at least one sub-area in the second step, so that both images are recognizable. In the third step, the camera is positioned in such a way that the search image overlaps the blended-in still image in at least one sub-area. The second recording process is initiated in a fourth step.

摘要： A descaling device for slabs or strips in hot rolling mills includes nozzles fed by a pressurized water piston pump for directing water jets against the slab or strip for removing scale adhering to the surface of the slab or strip. At least one additional pressurized water piston pump is provided, wherein the piston pumps are connected in parallel and the pumps can be switched on and off separately. A second row of nozzles may be arranged in front of the nozzles at a distance which ensures that the water jets do not influence each other. The water pressure of the water supplied to the second row of nozzles is preferably lower than the water pressure supplied to the first row of nozzles.

摘要： A driver for rolled strip includes a first roll which is mounted so as to be essentially stationary and a second roll which is adjustable relative to the first roll. The second roll is supported in a swivel frame which is adjustable by a pressure medium cylinder. The swivel frame is composed of two oppositely located links which are connected in the area of their common swivelling axis by a base which is supported on both sides thereof in the driver frame. The links can be adjusted by pressure medium cylinders which can be actuated separately and the base connecting the links is constructed as a torsion spring.
