Cold cathode ionization gage has rigid metal housing
Cold cathode ionization gage in a stainless steel housing accurately measures high pressures. The penning effect is used with a high voltage discharge in the presence of a magnetic field for an ion current proportional to the gas pressure in the gage.

Rod and dish cathode improves penning-type vacuum gage
Improved penning-type ionization gage provides range and sensitivity required to measure gas pressure below .01 torr under high vacuum conditions. The gage uses a highly conductive cathode composed of two disks of high magnetic permeability separated by a rod of low magnetic permeability.

Luminescent screen composition for cathode ray tubes
Screen composition for cathode ray tubes exhibits differential color of emission as a function of beam current variation at a constant accelerating voltage. The screen consists of a mixture of phosphors which emit different hues, have different current saturation values and exhibit a nonlinear current-brightness characteristic.
