Long-range-ordered alloys modified by Group IV-B metals (open access)

Long-range-ordered alloys modified by Group IV-B metals

Ductile long range ordered alloys having high critical ordering temperatures exist in the (V,M)(Fe,Ni,Co)/sub 3/ system having the composition comprising by weight 20.6 to 22.6% V, 14 to 50% Fe, 0 to 64% Co, and 0 to 40% Ni, and 0.4 to 1.4% M, where M is a metal selected from the group consisting of Ti, Zr, Hf, and their mixtures. These modified alloys have an electron density no greater than 8.00 and exhibit marked increases at elevated temperature in ductility and other mechanical properties over previously known ordered alloys.

Method of recovery of alkali-metal constituents from coal-conversion residues. [Patent application] (open access)

Method of recovery of alkali-metal constituents from coal-conversion residues. [Patent application]

A coal gasification operation or similar conversion process is carried out in the presence of an alkali metal-containing catalyst producing char particles containing alkali metal residues. Alkali metal constituents are recovered from the particles by burning the particles to increase their size and density and then leaching the particles of increased size and density with water, to extract the water-soluble alkali metal constituents.

ac-resistance-measuring instrument (open access)

ac-resistance-measuring instrument

An auto-ranging ac resistance measuring instrument for remote measurement of the resistance of an electrical device or circuit connected to the instrument includes a signal generator which generates an ac excitation signal for application to a load, including the device and the transmission line, a monitoring circuit which provides a digitally encoded signal representing the voltage across the load, and a microprocessor which operates under program control to provide an auto-ranging function by which range resistance is connected in circuit with the load to limit the load voltage to an acceptable range for the instrument, and an auto-compensating function by which compensating capacitance is connected in shunt with the range resistance to compensate for the effects of line capacitance.

Catalytic-cartridge SO/sub 3/ decomposer (open access)

Catalytic-cartridge SO/sub 3/ decomposer

A catalytic cartridge internally heated is utilized as a SO/sub 3/ decomposer for thermochemical hydrogen production. The cartridge has two embodiments, a cross-flow cartridge and an axial flow cartridge. In the cross-flow cartridge, SO/sub 3/ gas is flowed through a chamber and incident normally to a catalyst coated tube extending through the chamber, the catalyst coated tube being internally heated. In the axial-flow cartridge, SO/sub 3/ gas is flowed through the annular space between concentric inner and outer cylindrical walls, the inner cylindrical wall being coated by a catalyst and being internally heated. The modular cartridge decomposer provides high thermal efficiency, high conversion efficiency, and increased safety.
