A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets introduced by Sir John Herschel in 1842. [1] The process allowed rapid and accurate production of an unlimited number of copies.
Whiteprint describes a document reproduction produced by using the diazo chemical process. [1] It is also known as the blue-line process since the result is blue lines on a white background. It is a contact printing process that accurately reproduces the original in size, but cannot reproduce continuous tones or colors.
This would raise the temperature of the ore to the point where its sulfur content would become its source of fuel, and the roasting process could continue without external fuel sources. Early sulfide roasting was practiced in this manner in "open hearth" roasters, which were manually stirred (a practice called "rabbling") using rake-like tools ...
A US defense agent scanning in architectural documents. Architectural reprography, the reprography of architectural drawings, covers a variety of technologies, media, and supports typically used to make multiple copies of original technical drawings and related records created by architects, landscape architects, engineers, surveyors, mapmakers and other professionals in building and ...
The naturally occurring mineral binary compounds of copper and sulfur are listed below. Investigations of covellite indicate that there are other metastable Cu-S phases still to be fully characterised. [1] CuS 2, villamaninite [2] or (Cu,Ni,Co,Fe)S 2 [3] CuS, covellite, [2] copper monosulfide; Cu 9 S 8 (Cu 1.12 S), yarrowite [4] Cu 39 S 28 (Cu ...
Iron sulfides occur widely in nature in the form of iron–sulfur proteins. As organic matter decays under low-oxygen (or hypoxic) conditions such as in swamps or dead zones of lakes and oceans, sulfate-reducing bacteria reduce various sulfates present in the water, producing hydrogen sulfide. Some of the hydrogen sulfide will react with metal ...
