An automated planer machine for planing a piece of lumber. The planer machine has a feed table for slidably receiving the bottom surface of the piece of lumber along a traveling course. One or more planing heads extend on sides of the traveling course to plane the surfaces of the piece of lumber. A linebar laterally guides the piece of lumber. Feed rolls along the traveling course move the piece o...

The invention features a soft foam sled board for use by a sitting or kneeling rider to slide over a snow or ice covered surface. The sled is prepared from a shaped polyethylene foam core, and at least the bottom surface of the core is covered by a slick, polyethylene film/polyethylene foam sheet laminate which provides little frictional resistance between the sled board and sliding surface, and p...

Methods are disclosed for identifying and treating oil sand ores having degraded bitumen. This can be done by considering the location from which the ore is mined or its history, or by microscopic examination of a bitumen froth made from the ore, or by near-infrared spectroscopy. Ore which contains degraded bitumen is treated with at least 0.05 wt/wt % alkaline material, preferably 0.1 wt./wt % of...

A belt feed apparatus receives and feeds a continuous web of expanded graphite. The apparatus comprises a First pair of endless belts for receiving the web of expanded graphite therebetween, a drive motor operably connected to the first pair of belts for driving the first pair of belts at a drive speed, a controller for varying the drive speed, and a first load means for varying a friction force a...

The invention relates to a wind power plant with a tower, a rotor having at least one rotor blade being substantially radially distant with respect to a rotor axis and being rotatably supported with respect to a substantially horizontal rotation axis in a portion at the top of said tower, preferably at machine nacelle rotatably supported on a rotation axis extending substantially along the gravita...

In order to improve visibility and hence to reduce the risk of accidents, a rope, for example a wire rope, is equipped with a number of luminous elements (6, 8, 15, 15', 66, 86) . A luminous element (6, 8, 15, 66, 86) may in this case assume the position of a wire or of a braid, may be integrated in an insert, or may be guided in the spaces between wires or braids or, preferably, the theoretical r...
