Abstract: A near netshape carbon preform is provided comprising a polar woven fabric of a plurality of carbon yarns, said polar woven fabric having a helical shape and an adjustable fiber orientation distribution, said polar woven fabric being laid down, turn by turn, into a near net shape preform, and each layer of said fabric being needled to produce a near net shape preform with increased interlaminar strength, an adjustable fiber orientation distribution and enhanced thermal conductivity. A method for manufacturing a near net shape carbon preform with a polar woven substrate is also disclosed.

Abstract: This invention relates to a toothpick holder and toothpicks. The toothpicks are provided in and securely attached by at least one part to a support means which provides protection on at least one end and both sides of the toothpick or toothpicks in one plane. The toothpick or toothpicks are therefore protected from damage by unintentional forces applied in those planes. The toothpick holder will generally incorporate a plurality of toothpicks, and may also include a holding means for used toothpicks and a base plate for securing the holder in a match-book-type folder. The invention also relates to particular designs of toothpicks held in the support means, said toothpicks having a substantially square or rectangular handle end and a scalpel-shaped blade end, upper and side edges of which come to a point to form the pick end.
