  • Anemometer
    Patent number: 5195367
    Abstract: An anemometer having a surface resistor disposed on a substrate and having a meander shaped current path imprinted into it. To permit presetting of the resistance value of the current path, resistance trimming lines are disposed parallel to the partition lines that limit the current path.
    Type: Grant
    Filed: June 24, 1991
    Date of Patent: March 23, 1993

  • Process and apparatus for the production of fillings in teeth
    Patent number: 4634383
    Abstract: Gold powder is inserted in a cavity for the production of fillings in teeth by means of filled gold and this is subsequently hardened mechanically. The moisture sensitivity of this process can be avoided by using a paste made of platelet shaped gold powder with a plastic, organic binder which liquifies at 20.degree. to 45.degree. C. and the mechanical hardening is carried out with ultrasonic.
    Type: Grant

    Assignee: Degussa Aktiengesellschaft
    Inventors: Hans-Hermann Beyer, Walter Diehl, Karlheinz Eckert, Kurt Eiermann, Hans-Martin Ringelstein
  • Process for the production of fillings for teeth
    Patent number: 4610631
    Abstract: Powder of a ductile, mouth resistant metal such as silver, platinum, palladium, aluminum, or titanium, or an alloy thereof, or a cold weldable, mouth resistant synthetic resin, such as a polyacrylate or methacrylate, polycarbonate or polysulfone is worked to a paste with a plastic organic binder which liquifies at 20.degree. to 45.degree. C. This paste is hardened in the tooth cavity by ultrasonic action.
