Semiautomatic MDF deburring tool. [Mild detonating fuse]

Description: A device for semiautomatically deburring the ends of lengths of MDF (mild detonating fuse) was developed by the Automation Development group at Mound Laboratory. The device performs the deburring function by cutting a 0.002 in. x 0.002 in. chamfer on the MDF with small rotating blades. This air-operated, semiautomatic device provides improvement over the manual method of removing burrs by reduction in time and operator strain. A time study is underway to determine the time saved which is expect… more

Effect of the relative humidity in test atmospheres on uranium--0. 75% titanium and uranium--2. 25% niobium alloys

Description: Tensile tests of uranium--0.75 percent titanium and uranium--2.25 percent niobium alloys showed decreased ductility values with an increased humidity of the test atmosphere (12 to 80 percent rh). Similar results were obtained when the specimens were coated with a commercial rust preventive prior to testing. Results show that testing of the alloys should not be performed in laboratory atmospheres above a 50 percent relative humidity. The tensile-test ductility was not degraded in a dry argon atm… more
