Abstract

An ultraviolet absorption hygrometer is provided including a source of pulsed ultraviolet radiation for providing radiation in a first wavelength region where water absorbs significantly and in a second proximate wavelength region where water absorbs weakly. Ultraviolet radiation in the first and second regions which has been transmitted through a sample path of atmosphere is detected. The intensity of the radiation transmitted in each of the first and second regions is compared and from this comparison the amount of water in the sample path is determined. 5 figs.

Development of an ultraviolet absorption hygrometer for industrial dryers. Phase I. Final report

Technical Report Gersh, M E; Matthew, M W; Bien, F; ...

The breadboard version of the UVAH was successfully designed and fabricated. During this process, tests were performed on the components and assemblies in order to assure the validity of the design concepts. A performance model of the UVAH was developed on the SSI computer, in order to guide the design, assess the performance, and analyze the data of the UVAH. The success of the design effort was demonstrated by the results of the system performance tests. These tests demonstrated that the UVAH could measure the absolute humidity of a (clean) test chamber between temperatures of 50 to 90/sup 0/C andmore »« less
Development of a prototype ultraviolet absorption hygrometer for industrial dryers: Phase 2: Final report

Technical Report Gersh, M E; Domingue, R P; Matthew, M W; ...

The motivation for this program is the observation that the use of reliable and accurate hygrometers to monitor or control the processes in industrial drying chambers could result in a significant reduction in the energy usage of the United States. At the present time, there are no commercially available hygrometers which have the required characteristics of a measurement capability at simultaneously high temperature and humidity, along with the ability to operate for long periods in a severely contaminating and/or particle-laden environment. The goal of this program is the development of an industrial hygrometer which can be employed to monitor themore »« less

Magnetic fluorescent lamp having reduced ultraviolet self-absorption

Patent Berman, Samuel M [San Francisco, CA]; Richardson, Robert W [Pelham, NY]

The radiant emission of a mercury-argon discharge in a fluorescent lamp assembly (10) is enhanced by providing means (30) for establishing a magnetic field with lines of force along the path of electron flow through the bulb (12) of the lamp assembly, to provide Zeeman splitting of the ultraviolet spectral line. Optimum results are obtained when the magnetic field strength causes a Zeeman splitting of approximately 1.7 times the thermal line width.
