Determination of Manganese in Urine by Atomic Absorption Spectrometry

Abstract: An analytical procedure was developed for the determination of urinary manganese by atomic absorption spectrometry. Manganese is extracted from a buffered solution of the ashed urine salts by complexing the metal with 8-hydroxyquino-line and extracting with MIBK-CHCl3. The extract is then treated with acid, and the acid solution is aspirated into the instrument for the determination of microgram quantities of manganese. The accuracy and precision of the analytical technique were evaluated by comparison with data obtained on identical samples by means of spectrographic analysis.

Wire rope and strand unreeling apparatus

Abstract: A system and apparatus for unreeling wire rope and strand in which reels of rope or strand are rotatably journaled upon especially designed fork lift pallets and stored in unreeling position upon especially designed structural racks positioned such that any one of a number of ropes or strands can be drawn as needed from the rack and through a length measuring mechanism prior to delivery to a customer.

STRESS-CORROSION CRACKING BEHAVIOR OF AN 18% Ni MARAGING STEEL

Abstract: Stress-corrosion cracking of an 18 pct Ni maraging steel in aqueous solutions was studied using precracked cantilever beam specimens. By appropriate heat treatments, six different structures having the same yield strength were obtained. Although significantly different plane strain fracture toughness values (KIc) resulted, it was found that the threshold plane strain stress intensity (KIscc) was the same for all structures.KIscc had the same value in 3 pct NaCl at various pH values, in 1N H2SO4, and in distilled water. Specimens tested in 3 pct NaCl under both anodic and cathodic applied potentials also exhibited this sameKIscc value. Fractographic inspection of the crack surfaces revealed no apparent differences due to changes in solution, pH, or applied potential. The crack path was intergranular in all cases. However, specimens austenitized at 1500°F exhibited crack branching, whereas in specimens austenized at much higher temperatures branching no longer occurred. Aging time and temperature seemed to change only the time to failure. The mechanism most consistent with all observations appears to be hydrogen cracking.
