Patent number: 5503928Abstract: In the manufacture of reinforced composites having reinforcing filaments within a matrix, a filament consisting of a staple yarn spun from discontinuous fibers with low twist is subject to controlled stretching to vary the weight per unit length of the yarn along the length of the yarn. Apparatus for performing the stretching operation comprises two roll pairs spaced apart along the yard feed path and rotated at controlled relative speeds to obtain the desired elongation of the yarn. The yarn may be used directly in producing a composite, e.g., by applying resin to the yarn and winding it onto a mandrel or former, or it may be used to prepare a perform, prepeg tape, woven fabric or the like to be used in the production of a shaped composite. The invention makes it possible to vary the characteristics, e.g., thickness and/or strength, over a composite in a way not previously possible.Type: GrantFiled: August 18, 1992Date of Patent: April 2, 1996Assignee: New Millennium Composites LimitedInventor: Edward J.

Patent number: 5500266Abstract: When a dye material layer is spin-coated on an optical storage medium of the type having grooves fabricated in a substrate thereof, the dye material layer surface has depressions in the vicinity of the grooves. These depressions have a profile which is a function of the distance from the center of the storage medium. To compensate for the radial dependence of the depressions, the geometry of the grooves is changed by varying the base dimension of the groove as a function of the distance from the center of the storage medium. In this manner, the difference in phase for radiation traversing the storage medium by an optical path that includes a groove as compared to an optical path that does not include an associated groove is constant as a function of distance from the center of the storage medium. The phase difference which is a constant as a function of distance from the center of the storage medium is important in the generation of signals used in tracking the groove.Type: GrantFiled: March 10, 1994Date of Patent: March 19, 1996Assignee: Eastman Kodak CompanyInventor: James E.
