  • Patent number: 6734952
    Abstract: In geodetic measuring systems and measuring devices (14) there exists a need to find and detect, rapidly and automatically, marker points to be measured that are provided with a marker (retro reflector) (2a). For the rapid detection, identification and determination of the horizontal angles of such a marker, even at greater distances, electromagnetic radiation in the form of a vertical fan (17) is transmitted by a transmitter unit (1) whose radiation is received, after reflection from the marker, by a receiving unit with a view field in the form of a vertical fan. By analyzing the signal strength and the apparent object size, a plausibility test and a reliable suppression of foreign or interference markers can be achieved. Such a marker searching device is marked by a selective analysis of specific characteristics of a marker detected. On the basis of the plausibility test, a rapid, certain and robust location of markers is possible.

  • Patent number: 6126732
    Abstract: A shaped, high-strength dental ceramic prothesis is made by pressing a molding composition comprising about 1-50 wt % glass particles and about 50-99 wt % ceramic particles to form a ceramic frame, veneering the frame and firing the coated frame.

  • Patent number: 6031606
    Abstract: The invention relates to a process and device for the rapid detection of the position of a target marking. The target marking is picked-up by imaging optics and a local opto-electronic detector of a theodolite or tachymeter. Electric signals from the detector are rapidly evaluated in a pre-processing unit by formation of sum functions for determining coordinates of the target marking in such a way that the target marking is immediately automatically detected in coarse targeting and its further movement can be followed automatically. Its track data can simultaneously be recorded.

  • Patent number: 5916498
    Abstract: A process for manufacturing a non-metallic dental prosthesis including a ceramic frame and an esthetic ceramic veneer including the steps of: preparing the ceramic frame by press molding a composition comprising from 1 to 50 parts by weight glass particles and from 50 to 99 parts by weight ceramic particles at a molding temperature from 800 to 1300.degree. C.; applying a slurry comprising a dental ceramic veneering composition to the thus prepared ceramic frame; and firing the ceramic frame having the slurry applied thereto at a temperature lower than the molding temperature to produce said dental prosthesis. The dental ceramic veneering composition may have a melting point at least 50.degree. C. less than the molding temperature.

  • Patent number: 5849068
    Abstract: A shaped, high-strength dental ceramic prosthesis is made by pressing a molding composition including from about 1 to 50 percent by weight glass particles and from about 99 to about 50 percent by weight inorganic oxide particles at a pressure of from about 10 to about 40 MPa and a temperature of from about 1000.degree. to about 1200.degree. C. Dental prostheses prepared in accordance with the invention include crowns, bridges, inlays and onlays.

  • Patent number: 4829858
    Abstract: In order to ergonomically optimize the hand side of combination pliers, whose gripping arms in each case form a mouth jaw on their ends and are in operative connection by means of a joint in such a way that in the case of different activities with the pliers the adaptation of the gripping arms to the anatomy and anthropometry of the human hand is retained, it is proposed that the gripping arms face one another elliptically in the plane thereof and that in the vicinity of the coupling surface to the hand the gripping arms have an elliptical cross-section.

  • Patent number: 4748876
    Abstract: Prior universal pliers with two gripping arms (11, 15) and an adjustable jaw have the disadvantage that during adjustment one must change hands while using the pliers which is unfavourable as regards the economic requirements. This disadvantage is obviated by the present invention in that both gripping arms (11, 15) are non-displaceably articulated on one another and one of the two jaws (19) is displaceably mounted with respect to its associated gripping arm (15) at right angles to the jaw opening.

  • Patent number: 4046855
    Abstract: A method is provided for removing harmful organic compounds from the aluminate liquor obtained in the production of alumina according to the Bayer process. A magnesium obtained is added to the aluminate liquor to form a hydroxide mixture containing magnesium hydroxide and aluminum hydroxide which precipitates from the aluminate liquor. The precipitated mixture is maintained in the aluminate liquor, while being stirred, until at least a part of the organic compounds have been eliminated from the aluminate liquor. The hydroxide mixture containing the organic compounds then is separated from the aluminate liquor.

  • Patent number: 3986975
    Abstract: Red mud from the production of alumina from bauxite by the Bayer process is converted to a flocculating agent by reaction with sulfuric acid and drying the reaction product by direct heat transfer thereto by contact with hot solid bodies and by contact with hot gases. The resulting solid product is a mixture of water-soluble sulfates of iron and aluminum with minor proportions of other water-soluble metal sulfates in the form of free-flowing discrete particles.
