| 20080251296 | Countersink Roof Bit Drill And Method For Using The Same - A roof bit drill has a central shaft with a front end and a back end. The drill also has a base secured about the central shaft proximate to the front end, wherein the base has clearance channels extending axially therethrough. At least one cutting element is arranged on the base in a convex cutting pattern to permit loosened material to be evacuated. The roof bit drill may further include a drill depth locator to identify when the drill has been advanced within a mine roof to a predetermined depth. A method for using the roof drill bit is also disclosed herein. | 10-16-2008 |

| 20120024607 | Dust Collecting Device For A Roof Tool - A dust collecting device disposed circumferentially around a roof tool and in association with a roof drill bit and slidable thereon for collecting and removing dust generated during a dry drilling operation. The dust collecting device comprises a cylinder member, a bushing, and a mounting assembly comprising a top washer, a rubber insert, and a bottom washer. Another aspect of the invention provides a dust collecting device comprising a cylinder member, a bushing, and a mounting assembly comprising a disk and clips. The rubber insert and the clips resist movement of the dust collecting device along the drill steel of the roof tool during the drilling operation. | 02-02-2012 |

| 20110052128 | Optical Fiber Preform With Improved Air/Glass Interface Structure - An optical fiber preform comprising a plurality of longitudinal air holes is subjected to a thermal treatment (i.e., heating), coupled with the application of a compressive force on either end of the heated preform to compress the entire preform structure a predetermined amount. The thermal compression treatment has been found to smooth any roughened glass surfaces and heal microcracks that may have formed during the preform fabrication process, essentially “knitting” the glass material back together and forming a preform of improved quality over the prior art microstructured preforms. | 03-03-2011 |
