Abstract: A multilayered flexible sheet for absorbing liquids comprises a nonsegmented flexible layer comprised of woven or nonwoven materials having the capacity to absorb liquids and a segmented flexible layer of woven or nonwoven materials having the capacity to absorb liquids being tacked face-to-face to the nonsegmented layer, the segments of the segmented layer being separated by substantially straight boundaries extending across one dimension of the sheet. The multilayered sheet can be easily folded along the boundaries between the segments of the segmented layer and therefore can be used unfolded as walk on mats, wipes, absorbent pads and response pads or folded as pillows or socks for absorbing liquids.

Abstract: Devices for holding mining and road maintenance cutter bits, wherein said devices for holding comprise a cutter bit support block, a clevis and a support block locking mechanism whose geometries have been adapted such that the cutter bit support block can be fixedly and rigidly held in a channel in the clevis by the support block locking mechanism, which has a locking bolt. The support block locking mechanism and the clevis have means for interacting and cooperating such that each abuts with, and applies a downward pressure to, a lower body portion of the support block and thereby drives downward facing longitudinal shoulders on the support block into abutment under pressure with upward facing abutment shoulders of two longitudinal walls forming the channel in the clevis.

Abstract: A method and apparatus for installing chemical anchor bolt assemblies in earth formations comprising the step of abutting the end of the anchor bolt protruding from the earth formation with a predetermined force such that turning of the nut on the end of the anchor bolt will cause the anchor bolt to turn in the hole formation.
