  • Patent number: 6951628
    Abstract: A method for producing a scattered radiation grid or collimator which, for an incident radiation type, has transmissive regions and nontransmissive regions of predeterminable geometry. First the geometry of the transmissive and the nontransmissive regions of the scattered radiation grid or collimator is set. On the basis of this geometry, a base body is constructed according to the geometry, optionally differing by a particular layer thickness, of the transmissive regions or the nontransmissive regions by a rapid prototyping technique through layer-wise solidification of a structural material under the action of radiation. On the basis of this base body, the scattered radiation grid or collimator is finally completed.

  • Patent number: 6942826
    Abstract: Method for spectroscopically monitoring resin applied to a planar surface of veneer-wood sheets during travel in an assembly line. Spectroscopic instrumentation for monitoring applied resin is calibrated by measurements of predetermined resin applications to reference-test-samples, so as to provide a pre-determined relationship enabling monitoring of applied resin, during commercial production of a veneer-wood product using the visible light spectrum and near infrared extending to 2500 nm. Monitoring of selected radiation absorbance by the applied resin is carried out by spectroscopic measurement of non-absorbed electromagnetic radiation, as reflected back by the wood-veneer matrix; selected wavelengths are utilized for determining average resin-weight per designated surface area of a sheet.

  • Patent number: 6939500
    Abstract: Method and apparatus for molding a sealing surface of revolution on a molded part in first and second partable mold halves that mate at a major parting line plane. First and second mold inserts each have a sub-insert trim wheel component shaped to mold form the sealing surface of revolution when closed at a minor parting line plane. The sub-inserts are rotatable between a position flush with the major parting line plane and a starting position angularly offset therefrom. The mold cavity is filled with liquid molding material that is allowed to harden to at least a self-sustaining solidification strength. The sub-inserts are then rotated to thereby move any minor parting line flash toward a position angularly offset from their starting position. This rotation causes any parting line flash that might otherwise remain on the sealing surface to be removed from attachment to, and/or smeared smooth along, such surface.

  • Patent number: 6911169
    Abstract: A method of making a composite article of a graphite-filled polymer mixture that is robust during high shear mixing and compounding, and that exhibits relatively low electrical resistivity after molding. The mixture is formed by shear mixing a liquid polymeric material, graphitized carbon fibers having diameters of less than one micrometer, and glass fibers longer than the carbon fibers. The carbon and glass fibers constitute up to about 25 volume percent and up to about 50 weight percent, respectively, of the mixture, though the addition of as little as about 1 weight percent of the glass fibers has been shown to dramatically reduce resistivity. The mixture is then introduced into a mold so that the glass fibers are substantially oriented parallel to the direction of flow.
