It is a still further object of our invention to provide new and improved methods and apparatus for the utilization of hydrocarbon fluids in the production of visually opaque aerosols.

It is a further object of our invention to pro- vide new and improved methods and apparatus for obtaining the maximum obscuring power of an aerosol by controlling the droplet size whereby …

It is an object of our invention to provide new and improved methods and apparatus for the production of aerosols or suspensions of matter 30 such as fluids in an atmosphere.

In 1943, the focus of Schaefer's and Langmuir's research shifted to precipitation static, aircraft icing, ice nuclei, and cloud physics, and many of their experiments were carried out at Mount …

From an aircraft over Massachusetts, he seeded clouds with pellets of dry ice (solid carbon dioxide) and succeeded in producing snow, initiating the science of experimental meteorology …

Finally during the past year arrangements were com-pleted for Schaefer, Falconer, Vonnegut and Blanchard to work together again as part of the Atmospheric Sci-ences Research Center of …

"The Vapor Method for Making Replicas of Liquid and Solid Aerosols," V.J. Schaefer, Undated

During World War II Schaefer had worked on atmospheric research and, more specifically, the problem of airplane wings icing up, and had discovered that he could produce a snow storm in …
