Patent number: 7819609Abstract: A module is for use in drilling a borehole in a face of a mine passage using a drilling element and installing a bolt in the borehole once formed. The module may include a bolt holder for holding a plurality of bolts and a drilling element holder for holding a plurality of different drilling elements. A manipulator moves along an arcuate path between the bolt and drilling element holders to deliver the respective components to a drill head positioned along the arcuate path. The drill head may also slide relative to the mast in two different directions, and includes a drill guide for determining the location of the face to be worked. Related aspects of control of the module and methods are disclosed.Type: GrantFiled: July 5, 2007Date of Patent: October 26, 2010Assignee: J.H. Fletcher & Co.Inventors: Gregory E. Hinshaw, Henry E. Wilson, Craig M. Collins, William A. Kyslinger, William B. Schwab

Patent number: 5951208Abstract: A method of roof/side wall roof bolting in-situ includes the steps of drilling a bore hole, loading a rupturable resin cartridge into a lightweight, tubular wand through the delivery end, manually placing the wand with the delivery end adjacent the mouth of the bore hole, pushing the cartridge through the wand for transfer into the bore hole, and inserting the roof bolt to rupture the cartridge and for setting into place in the rock. The related apparatus includes a tubular wand, a flexible pusher that is extensible through the wand and into the bore hole for transfer of the cartridge and a driver in the form of a flexible snake assembly from a reel to push the cartridge. The snake assembly includes a cylindrical head on the end and a plastic retainer fits over the trailing end of the cartridge to prevent retro movement and to provide protection from premature rupture. A handle at the proximate end of the wand provides for easy manipulation of the wand.Type: GrantFiled: June 13, 1997Date of Patent: September 14, 1999Assignee: J. H.

Patent number: 4141224Abstract: A closed loop apparatus for spraying coolant against the back of a radiation target. The coolant is circulated through a closed loop with a bubble of inert gas being maintained around the spray. Mesh material is disposed between the bubble and the surface of the liquid coolant which is below the bubble at a predetermined level. In a second embodiment no inert gas is used, the bubble consisting of vapor produced when the coolant is sprayed against the target.Type: GrantFiled: August 31, 1977Date of Patent: February 27, 1979Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Donald L. Alger, William B. Schwab, Edward R. Furman
