Title: Method for developing enhanced texture in titanium alloys, and articles made thereby
Inventor: AMATO RICHARD ANTHONY
IPC: B22F3/20
Filed: 1990-07-30
Abstract: Enhanced crystallographic texture is developed in an alpha or alpha-beta titanium alloy having a dispersion of particles therein, by heating the alloy to essentially the all beta phase range and mechanically hot working the alloy in this range. The mechanical working is preferably accomplished by extrusion, rolling, or forging. The particles are stable during working, and prevent the formation of random texture in recrystallized beta phase grains at the working temperature. The particles are preferably oxides formed from rare earth elements such as erbium or yttrium, that are introduced into the alloy during manufacture. The alloys processed according to the invention are preferably prepared by powder metallurgy to achieve a uniform microstructure prior to working. A particularly suitable alpha-beta (but near alpha) titanium alloy contains aluminum, zirconium, hafnium, tin, columbium, molybdenum, tungsten, ruthenium, germanium, silicon, and erbium.

Title: Angle divider
Inventor: SMITH DAVID
IPC: B27G5/02
Filed: 1991-08-08
Abstract: An angle divider is a tool designed to automatically divide any given angle, ideal for use in mitering. It works by placing the tool on or inside the known angle with both movable arms 7 running parallel along either side of that angle. Because the arms have an intermeshing gear mechanism at one end pivoting in a main body 9 the movement of each arm is dependent on the other and so keeping the main body central to both arms. A detachable dividing arm 6 is located on the main body, the angle between it and either movable arm will be exactly half that of the overall angle. <IMAGE>
