Progress in Environmental Specimen Banking (open access)

Progress in Environmental Specimen Banking

In October, 1986, the 10th U.S.-German Seminar of State and Planning on Environmental Specimen Banking was held at the Virginia Institute of Marine Sciences in Gloucester Point, Virginia. At this meeting the current status of specimen banking activities in the U. S., FRG, Canada, and Japan was presented and discussed. This publication contains the proceedings of that meeting with contributions describing various activities related to banking and analysis of samples from aquatic, atmospheric, terrestrial, and human monitoring programs.

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France (open access)

Stone Dusting or Rock Dusting to Prevent Coal-Dust Explosions, as Practiced in Great Britain and France

From Introduction: "Coal dust as an agent of widespread explosions had been under suspicion, and watering to allay the dust was recommended by some mining engineers but the watering of coal-mine dust was adopted in comparatively few mines of the United States and Great Britain, and had not been introduced widely in any country except Germany. Rock dusting, another method of preventing explosions of coal dust, was early tested with success by the Bureau of Mines in its first gallery at Pittsburgh and, beginning in 1911, at the experimental mine, Bruceton, Pa."

Development of the Fischer-Tropsch Oil-Recycle Process

From Introduction: "This report on the development of the oil-recycle process covers: 1. Review of the work in Germany on the first oil-circulation process. 2. Work by the Bureau of Mines, United States Department of the Interior. (a) Preliminary experiments on a laboratory scale, consisting of orientation tests and bench-scale operation, employing a 1-foot bed of catalyst in a 3-inch diameter vessel. (b) Operation of 2 pilot plants with a 4- or - 8 foot bed of catalyst in 3-inch-diameter reactors. Up to 3 gallons of C2+ hydrocarbons was produced per day in each of these plants. (c) Operation of a barrel-per-day pilot plant with an 8-foot bed of catalyst in an 8-inch-diameter reactor."

From Introduction: "This part of Bulletin contains 250 European patents that relate to retorting (and distilling underground), refining, and utilization of oil shale and its products. The largest single group, of which the majority was assigned to a single company, relates to fluidized handling shale. The patents are arranged numerically, and alphabetical list of investors and assignees follow them. A classified list of all the patents follows the author index of Part III. Parts I and II were published in 1958."

An Index of Shale-Oil Patents

From Introduction: "Work on this project was begun early in 1944; and the results with respect to shale oil are reported in this Bulletin. Since this bulletin is only an index to this large repository of ideas relating to the the treatment of shale oil, the material is presented in the form of short notices describing the subject material of each patent, which consist of an abridgment of the patent (if British or Australian) or a typical claim in the case of the United States or foreign patents."
