Patent number: 6274230Abstract: A process for producing sharp surface visible patterns on composite articles formed of resin coated reinforcing strands employs a liquid uncured resin having a coloring component therein to produce an opaque resin of light color to mask the color of the reinforcing strands. An absorbent surface veil is applied to the surface of the article before curing the resin to produce an absorbent opaque surface layer of light color into which a pattern of contrasting color is then transferred by sublimating an ink or dye pattern from a pattern carrier into the opaque resin impregnated surface layer and veil. Articles ready for application of the surface pattern thereto by sublimation may be produced using pultrusion or hand lay-up methods. Distribution of the surface pattern partially or entirely through the thickness of the surface layer results in an article having a surface in which the pattern remains sharply visible despite surface wear.Type: GrantFiled: June 25, 1999Date of Patent: August 14, 2001Assignee: Jas.

Patent number: 6017284Abstract: A hollow archery arrow shaft has a rearward end portion which is reduced in inside diameter to frictionally receive and hold the mounting shank of a standard nock. This configuration eliminates the need for a bushing in the rearward end of the arrow shaft for accepting the mounting shank of the nock. Reduced arrow weight and better nock positioning and alignment results in faster and more accurate arrow flight. In aluminum arrows, the reduced diameter portion can be formed by swaging the end portion of the arrow shaft to the smaller diameter.Type: GrantFiled: October 1, 1998Date of Patent: January 25, 2000Assignee: Jas. D. Easton, Inc.Inventor: Kenny R. Giles
