  • Patent number: 5110291
    Abstract: Apparatus for bending dental instrument for use in root canals. The apparatus includes two rotatable sleeves made of plastic material one of which is carried by a stationary element which acts as a handle and the other one of which is carried by a movable member articulated on the handle. A coil spring interposed between the handle and the movable member urges the two sleeves to be maintained at distance one from each other. The blade of the instrument to be bent is engaged between the two sleeves when they are positioned distant from each other. A force then is exerted on the movable member for moving one of the sleeves toward the other one and pinching the blade of the instrument between them. Then, while the blade is pinched between the sleeves, a traction is exerted on the instrument accompanied with a lateral displacement that produces the bending of the blade.

  • Patent number: 5077487
    Abstract: A driver circuit for a large capacity switching element like power transistors etc. having an overdrive function. The driver circuit supplies a sharp overdrive current only at the build-up time and the control thereafter is effected by a constant current source so that the current limiting resistor can be saved and the current capacity of the various elements may be decreased.

  • Patent number: 5073200
    Abstract: An improved system for extracting soluble substances from fibrous material by using a plurality of maceration and compression steps thereby excerting moderate pressure on the fibrous material up to 15 bars.Arrangements are made to saturate the fibrous material to its maximum absortion potential between each pressure application. Moisture content of the agent fibrous material is finally reduced with the combined application of moderate and high pressure. The application of imbibition liquid in this area and the use of the solvent received for the purpose of maceration in the preceeding extraction steps is made in accordance with the respective concentration of the solvent.The extraction system can operate without the application of process heat; therefore, a lixiviator is not required. Two or more maceration and compression steps can be located in a module, thus permitting a very compact arrangement of the extraction system.

  • Patent number: 5062214
    Abstract: An absolute measuring scale system comprising a scale which extends along a measuring length, and a measuring head which is movable relative to the scale. The system further includes a fine-measurement sensor which is intended to measure the absolute values within each of a multiple of intervals lying sequentially along the scale, and a coarse-measurement sensor intended to measure the absolute values with regard to the interval within which the fine-measurement sensor is located at that moment. The invention is characterized in that the scale (2) comprises a carrier made of a transparent and form-stable material, preferably glass, which has provided on its surface an outer coating or layer which forms an opaque pattern (3, 4). The pattern formed along the length of the scale (2) forms transparent, mutually parallel binary code tracks (12), preferably in accordance with the so-called Grey-code.
