Plastic Flow During Extrusion of Tubing (open access)

Plastic Flow During Extrusion of Tubing

Abstract: "A study of plastic flow during the extrusion of tubing was made by extruding colored Plasticine billets in a small-scale extrusion press. Decreasing the included angle of the conical die and tapering the ram end of the billet decreased the amount of coextrusion of the backer block into the tubing, lubricating the billet also decreased coextrusion."

Note on Table Top Injection : High Energy Injection Inside the Mirrors

"High energy injection into Table Top is discussed for the case in which the ion sources are to be located inside the mirrors in the mirror region. Two typical ion source geometries are considered. maximum time intervals available for injection indicated are on the order of 7 to 25 microseconds."

The Grüneisen Parameter for an Einstein Solid and Under Finite Strain (open access)

The Grüneisen Parameter for an Einstein Solid and Under Finite Strain

The Grüneisen constant, as evaluated from the equation of state, is obtained for an Einstein solid. the presence of a state of finite hydrostatic pressure is taken into account explicitly by means of Murnaghan's theory of finite strain, to obtain the Grüneisen parameter's on the Debye and Einstein models. Results are identical in the two cases with the corresponding values obtained without use of the formal theory of finite strain.

Comparison of Flame Photometer and Conductivity Meter for the Determination of NaCl from Respirator Testing (open access)

Comparison of Flame Photometer and Conductivity Meter for the Determination of NaCl from Respirator Testing

periodically the Industrial Hygiene Unit has the occasion to perform efficiency tests on respiratory protective devices and on filter cartridges used with these units. A study of the relative merits of the flame photometer and conductivity meter was made to determine which is more applicable for the determination of NaCl in filter samples.

Interim Evaluation of the Fluorox Process for UF4 and UF6 Manufacture (open access)

Interim Evaluation of the Fluorox Process for UF4 and UF6 Manufacture

The conversion of UNH to UF4 and UF6, utilizing moving-bed techniques, is being studied; sufficient progress has been made that an evaluation of the process is warranted. The procedures under study, the Fluorox Process, have three major advantages: (1) substitution of HF for high-cost fluorine, (2) considerable reduction in HF requirements, and (3) marked reduction in plant-size and mechanical complexity.
