Patent number: 6028910Abstract: The present invention is related to laminographic apparatus and method for imaging individual layers of a multilayer structure, for example the individual layers of a composite, with capabilities for imaging in multiple dimensions or along arbitrary surfaces within the space of the structure. A source of radiation and an areal detector are moved relative to a test specimen positioned therebetween such that a magnified two dimensional image of the test specimen is obtained at the detector. A single translational pass of the test specimen through the source/detector combination provides sensitivity to patterns in the test specimen which have small scale features lying in a direction parallel to the direction of the pass. An image with sensitivity to features in two perpendicular directions is obtained by taking passes in both directions, no mechanical registration between the perpendicular passes being required.Type: GrantFiled: January 19, 1998Date of Patent: February 22, 2000Assignee: Foster-Miller, Inc.Inventors: Theodore E.

Patent number: 5882741Abstract: Coatings of multiaxially oriented Thermotropic Liquid Crystalline Polymer (TLCP) are provided to elongated members. Suitable members include glass rods, glass fibers, pipes, beams, and other oval or polygonal members having an essentially regular cross-section. Members of ceramic, plastic, or metal can also be coated. This extrusion is performed using a die having inner and outer mandrels capable of rotating in opposite directions. Concentricity between inner and outer mandrels of the die is maintained to assure uniform coating thickness. In order to produce a high level of multiaxial orientation at lower die rotational speeds, the die design may include spiraling feed zones on one or both facing surfaces of the inner and outer mandrels. The application of the multiaxially oriented coating provides superior impermeability to water vapor and oxygen, and increased strength to the elongated member in the axial direction.Type: GrantFiled: January 26, 1996Date of Patent: March 16, 1999Assignee: Foster-Miller, Inc.Inventors: Leslie S.
