Publication number: 20050011346Abstract: A carrier assembly for a gun comprises a gun bolt carrier disposed to reciprocate axially with respect to the central axis of the gun, and a gun bolt disposed to reciprocate axially within the carrier. The gun bolt has a locking groove therein. The assembly also comprises a bolt locking mechanism extending through a portion of the bolt carrier to selectively engage the locking groove and thereby prevent the bolt from moving with respect to the carrier. The assembly further comprises a generally axial groove in a non-reciprocating portion of the gun that engages and selectively rotates the rotatable bolt locking mechanism to selectively lock the bolt to the carrier.Type: ApplicationFiled: May 13, 2003Publication date: January 20, 2005Inventors: Peter Wolff, Peter Bates

Publication number: 20020171029Abstract: A nanowire array supports axially-propagating TEM modes. The resolution of the array is determined by the interwire spacing rather than by the optical wavelength. The resolution can be made smaller than the optical wavelength. A bipartite honeycomb configuration is the preferred structure to support the TEM modes. Each nearest neighbor wire pair in the array (from opposite classes in a bipartite nanowire array) can be viewed as a two-wire transmission line, embedded in the surrounding matrix. Selective pairs of nanowires can be activated with wire loops, in a manner similar to that used to couple light to coaxes. The pattern of the wire loops determines where the array is excited; hence where light is transmitted. In effect, loop positioning provides a method of “writing” a desired transmission pattern into a pristine array in a similar manner as lithography.Type: ApplicationFiled: March 28, 2001Publication date: November 21, 2002Applicant: NEC Research Institute, Inc.Inventor: Peter A. Wolff
