Patent CA-2338829-A1 (CA)
Inventor: BARLOW DUANE ANTHONY
IPC: B23C5/22
Filed: 2001-02-28
Abstract: The disc saw blade has a plurality of teeth detachably mounted in sockets provided in a rim portion around the circumference thereof. Each tooth has an anchoring portion, and a cutting edge which projects slightly from the circumference of the saw blade. The sockets each have an anchor-receiving portion to receive the anchoring portion of a tooth. The teeth and the sockets are configured such that each tooth is installed by inserting its anchoring portion into a corresponding anchor-receiving portion of a socket, in an axial direction, and then securing the tooth to prevent axial removal, for example by making the anchoring portion cylindrical and rotating the tooth rearwardly about a center of the cylindrical anchoring portion to position a keyway on a key portion extending into the socket, or by using a bolt threaded into or through the tooth. Radial removal is prevented by the anchoring portion being shaped such that it cannot be extracted from the anchor-receiving portion, except axially. For example, in the cylindrical anchor version, the anchoring portion is more than 180 degrees engaged within the cylindrical anchor-receiving portion of the socket. A bolt, pin or the like may be used to secure the tooth in its installed position. A small throw gap is achieved, and a large gullet is provided by each socket for wood chip clearance.

Title: Method and apparatus for improving light power handling capabilities of polymer fibers
Inventor: LI KENNETH K
IPC: G02B6/26
Filed: 2000-03-07
Abstract: The power handling capability of polymer fibers is increased by broadening a n input intensity profile, which is typically Gaussian, without significantly decreasing the efficiency of coupling light into a polymer fiber. The method  for increasing the power handling capability of polymer fibers includes the steps of: a) emitting light having a Gaussian intensity profile from a fiber  light source (100); b) broadening the Gaussian intensity profile so that energy at the center of the Gaussian intensity profile is distributed to the  perimeter to reduce the peak power intensity of the emitted light before it is launched into the polymer fiber; c) transmitting the emitted light into at least one polymer fiber (300). Preferably, a tapered or twisted fused bundle  (200) is used to broaden the intensity profile and preferably the fused bund le has an angled input end face. As a result, more total power can be coupled into the polymer fiber while keeping below the melting threshold caused by t he light absorption -- enabling, for example, power in excess of 1 Watt to be transmitted through a 1-mm diameter PMMA fiber.
