Definitions for "Patenting"
A heat treatment process often applied to high carbon wire. The steel is heated to a suitable temperature well above the transformation range, followed by cooling in air or a bath of molten lead or salt. A structure is produced suitable for subsequent cold drawing and which will give the desired mechanical properties in the finished state.
Heating iron-base alloys above the critical temperature range followed by cooling below that range in air, or in molten lead or a molten mixture of nitrates or nitrites maintained at a temperature usually between 800-1050°F., depending on the carbon content of the steel and the properties required of the finished product. PEARLITE-A relatively hard constituent of steel made up of alternate layers of ferrite (iron), and cementite (iron carbide; that is, a compound of iron and carbon). See "Eutectoid Steel"
The process of heating carbon steel above its critical temperature and cooling at a controlled rate to achieve a final pearlitic microstructure.
A process established under the General Mining Law of 1872 which permits the conversion of mining claims on federal lands into full fee ownership, provided certain conditions are met.
