Abstract: Mine run coal is pulverized and the extended surfaces of the coal particles are rendered hydrophobic and oilophilic by a chemical bonding and graft polymerization reaction with a water insoluble organic polymerizable monomer under peroxidation influence in a predominantly water reaction medium.The mineral ash present in the coal and particularly the iron pyrites remains hydrophilic and is separated from the polymeric organic surface bonded coal product in a water washing step wherein the washed coal floats on and is recovered from the water phase and the ash is removed with the separated wash water in a critical wash step.Excess water is removed from the beneficiated hydrophobic surface-altered coal product mechanically. The hydrophobic and oilophilic organic polymeric surface bonded coating about the coal particles is fortified by inclusion of additional unbound free fatty acids by further small additions thereof.

Abstract: Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body. The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path. The beading spindles are provided with beading tool portions corresponding to the chime and intermediate beads to be formed on a can body. The frame supports axially offset and sequentially arranged outer beading rails positioned along the arcuate path of spindle movement. During movement of the spindles along the path between input and output stations of the apparatus, can bodies on the spindles are rotated about the spindle axes and, as each can body moves past the outer beading rails, the beading tool portions of the spindles and the outer beading rails cooperatively engage a can body therebetween to sequentially form first the chime bead and then the intermediate beads on the can body.

Abstract: A web tension transducer device which is easily in-installed, has a high natural frequency, excellent linearity, and extremely low hysteresis. A twin beam type transducer having strain gages at the flex points of the beams is coupled to the shaft supporting the moving web through a self-aligning anti-friction bearing, the strain gages being so located and electrically connected that effects of friction in the bearing due to bending of the shaft are automatically cancelled out in the circuitry in which the strain gages are connected. The self-aligning bearing coupling is arranged to permit relative axial displacement between the shaft and the twin beam transducer for accommodating comparatively large amounts of shaft expansion. The bearing also may have a bearing surface liner comprised of a low coefficient of friction thermoplastic resin material such as teflon fiber or teflon fiber-filled acetal resin fabric.
