摘要： A self-propelled continuous mining machine includes a mobile frame assembly having a front end portion with a boom assembly pivotally retained thereon. A dust collecting system is positioned on the mobile frame assembly for inducing a flow of air through a hollow interior portion of the boom assembly. As a dislodging head removes material from a mine face, the dust collecting system draws airborne dust created by the dislodging head through a hollow interior of the boom assembly and into the collecting system mounted on the mobile frame assembly. Two portions of the boom assembly are pivotally connected to portions of the collecting system mounted on the mobile frame assembly to provide pivoting joints to allow the collecting system to draw airborne dust through the boom assembly with the boom assembly in any preselected position relative to the mobile frame assembly. Twin ducts of the collecting system meet the boom on each side of the mining machine and the ducts of the collecting system extend rearwardly along each side of the mobile frame assembly. A conveying system mounted on the mobile frame assembly receives material from the dislodging head and transports the material rearwardly of the machine. One of the twin ducts crosses to the other side of the mobile frame by passing between the conveying reach and the return reach of the conveying system and joins with the other duct so that a single fan may be used to draw airborne dust through the system.

摘要： An improved wastewater aeration and mixed liquor pumping arrangement for an orbital-type actuated sludge purification method includes the addition of a radial flow impeller on a shaft extension below the normal surface aerator. Both the combined radial flow impeller and surface aerator are positioned with respect to an end of a partition wall forming the flow channels of the orbital system such that both the impeller and the aerator pump the mixed liquor in the same direction, so that the mixed liquor is moved at a sufficient velocity through and around the various channels and returned. The radial flow impeller is positioned adjacent to the bottom of the orbital channel and enhances the propulsion of the mixed liquor along the bottom of the channel thus permitting deeper channels with attendant concrete and land area savings in constructing the system. The system may be operated at various wastewater levels so that when oxygenation levels are high or oxygenation needs are low, the level is lowered by a weir so that only the lower radial impeller functions to propel the mixed liquor. Auxiliary compressed or aspirated air may also be inputted through the lower radial impeller.

摘要： A single-pass roof bolt adapted to drill and to be secured in a bore in the roof of a mine for supporting the roof comprising a tubular body open at one end thereof, constituting the inner end of the bolt, and a cutting structure at the opposite end of the tubular body, constituting the outer end of the bolt. The bolt is adapted to drill a bore in the mine roof upon rotation of the bolt, with the cutting structure being wider than the tubular body for forming an annulus between the tubular body and the wall of the bore. The bolt has a head at its inner end to facilitate rotation of the bolt, and to bear against the mine proof in pressurized relationship. The tubular body further has a transfer port at its outer end, and is free of flow obstructions between its ends, whereby during drilling air is flowable through the bolt for removing cuttings from the bore, and upon completion of drilling grouting material from a source external to the roof bolt may be delivered to the annulus via the transfer port for securing the bolt in the bore. A roof bolting system including a machine for rotating, applying force and delivering the grouting material to the bolt to install it is also disclosed. In addition, a method of installing the bolt is disclosed.

摘要： A method of drilling a subterranean well utilizing a downhole drilling apparatus is disclosed. The apparatus has a driven rotary drive shaft and a relatively fixed tubular housing circumjacent the drive shaft, with the housing having an annular upwardly facing bearing surface at an angle to a longitudinal axis of the housing and an annular sealing surface facing downwardly at an angle to the axis and axially spaced above the upwardly facing bearing surface. The method includes the steps of securing the drilling apparatus to the lower end of a string of drill pipes suspended in the well with the longitudinal axis of the housing coincident with the longitudinal axis of the string of drill pipe. Thereafter, the drill bit is secured to the lower end of the drive shaft, and fluid is pumped through the drilling apparatus to rotate the drive shaft and the bit. A rotating bearing and sealing device is positioned and secured relative to the drive shaft remotely within the well and axially between the spaced-apart annular bearing surface and annular sealing surface, with the rotating bearing and sealing device having a lower annular surface bearing upon and in face-to-face contact with the upwardly facing bearing surface and having an upper annular surface biased upwardly against the annular sealing surface in face-to-face contact therewith, whereby the axially spaced-apart pairs of annular surfaces provided a seal between the shaft area within the downhole apparatus and that area radially external of said bearing and sealing surface.

摘要： A bearing supports a rotatable shaft in a fluid environment. The bearing can be utilized to support a drive shaft connected to a drill bit in a downhole drilling apparatus. The drive shaft extends through a housing in which drilling fluid is flowing. Preferably, the bearing includes an inner elastomeric sleeve and an outer rigid sleeve attached to the interior side wall of the housing. The drive shaft has a wear sleeve attached for rotation therewith. The wear sleeve is rotatably received in the bearing inner sleeve. The inner sleeve is relatively short as compared with the drive shaft and absorbs radial loads imposed on the drive shaft. The bearing is lubricated by a portion of the drilling fluid in the housing which flows between the exterior side wall of the wear sleeve and the interior side wall of the inner sleeve.

摘要： An apparatus, such as a shear-out safety joint, which is incorporated in a subterranean well tubing string for separating or severing the tubing string when subjected to excessive loads is disclosed. The shear-out safety joint is used with a safety valve and by providing a prescribed failure point will ensure that the safety valve remains intact. The apparatus includes inner and outer telescoping members which can separate when the tubing above and below the joint moves in opposite directions. A shear ring connecting the two telescoping members will shear when a predetermined load is applied. The joint also has a second releasable connecting member extending through the inner telescoping member and engaging the outer telescoping member which will support a load greater than that which can be carried by the shear ring. A longitudinally shiftable member, movable within a recess, holds the second connecting member in engagement but disengages the second connecting member when moved to a second position.
