The Effect of Geometry and Voltage Variations on the Operations of the Phillips Ion Gage

Description: Abstract: "The study of ten P.I.G. geometries with copper electrodes and d.c. voltage indicates that from a pressure of 0.1 to about 3.0 microns, depending upon the gage, there is a consistent change in the air pressure-current characteristics of a P.I.G. as the geometry and voltage are changed. At higher pressures discontinuities appear in the gage current and prohibit its use as a pressure gage. In all useful geometries, the greater the applied voltage above 1000 volts, the shorter the useful… more

100-F area unit purge, May 3, 1945

Description: This report discusses the pressure drop on the 100-F unit, as measured on the eight pressure drop tubes, which had increased to 24 lbs./in.{sup 2} above base by May 2. The unit was shut down on May 3 to purge with 50 ppm solids for 1.1 hr. and to take care of necessary maintenance work.

The Digging-in of a Warped Rod Into a Rib

Description: Abstract. Some rather idealized considerations are given regarding the depth a warped rod presses into the ribs at the places of contact. It appears that this distance may, under some conditions, be of the order of 70 times greater than for a straight rod resting uniformly on the ribs.
