A Mill for the Quantitative Grinding of TF₄
Abstract: "A monel metal rod mill has been designed, built, and tested for grinding five hundred gram batches of anhydrous tuballoy tetrafluoride to a fineness such that one hundred per cent will pass an eighty mesh screen; the grinding being accomplished without loss of material, and with the addition of less than two hundred parts per million of contaminating metals. The grinding time per batch is not more than fifty minutes."

Mine Flood Prevention and Control: Anthracite Region of Pennsylvania, Final Report of the Anthracite Flood-Prevention Project Engineers
Summary: "The engineering survey, summarized in this report, consisted of studies on acid mine water, underground-water pools, the "buried valley" of the Susquehanna River, inundated anthracite reserves, mine pumping plants, surface-water pools, seepage of surface water into mines, barrier pillars between mines, and geologic features of the region that included core drilling along alinement of the proposed Conowingo tunnel and to some extent along the proposed Marcus Hook alternate tunnel route. A comprehensive study was conducted to determine corrosion and erosion resistance of selected metals and alloys and to ascertain their suitability for components of pumps to be used in handling acid mine water."

Mine Pumping Plants: Anthracite Region of Pennsylvania
From Summary: "To obtain a reliable picture of the anthracite-mine-water problem and to solve that problem, it is necessary to have factual data on the volume and the quality and character of mine water handled by pumping plants in the anthracite region, as well as kinds of pumps utilized and problems concerning their operation. The main conclusion that be drawn from an investigation of drainage practices in the anthracite region is that, although efficient pumping layouts, tunnels for draining active mines, and large-scale surface-drainage facilities for keeping water out of mines are in use, the anthracite industry still is threatened with curtailment, to a major degree, and premature extinction because of the encroachment of water, unless remedial action is undertaken in the vary near future by all interests concerned."
