Visual-type hygrometer

TL;DR: In this article, the authors measured the time rates of change in the intensity of the transmitted radiant energy while the intensity is changing due to the perturbing pulse, after each such perturbation starts or ends or both, such rates were proportional to the concentration of the analyte in the medium.

TL;DR: In this article, the authors present a thermal imaging apparatus using the radiation detector scanned to form the thermal image as the radiometer detector. But the reference source temperature is not changed by the measuring apparatus.

TL;DR: In this paper, the authors proposed novel chemical compositions for use in primary, optical/capacitance hygrometric devices for precise measurements of the humidity of gases as well as the apparatus.

TL;DR: In this paper, the optical changes from a birefringent phase to a nonbireferingent phase due to change of water vapor pressure in the environment contiguous with any selected one of the compositions (3) and also as a function of the temperature of the same selected composition (3).

TL;DR: In this article, the authors describe a POROUS METAL-ION-CHAIN-BRIDged POLYMERIC product with surface area of at least 5 M.2/G.

TL;DR: In this paper, a VINYL POLYMER COMPLEX is described, which is used as a SIZING AGENT for the PAPER INDUSTRY and is also useful as a FLU-OCCULANT or a HEAT-SENSITIVE OR PRESSURE-sensitive ADHESIVE agent.
