US Classification:

342354, 342372, 342373, 343781 R

Abstract:

A antenna system for generating and distributing power among a plurality of non-focused beams is provided The system comprises a reflector having a focal plane and a non-parabolic curvature configured to form the defocused beams. The curvature is configured to create a symmetrical quadratic phase-front in an aperture plane of the reflector. The system further comprises a plurality of feed antennas disposed in the focal plane of the reflector and configured to illuminate the reflector. Each feed antenna is configured to contribute power toward each of the defocused beams. The system further comprises a plurality of fixed-amplitude amplifiers, at least one of which corresponds to each feed antenna.

Abstract:

This invention relates to the use of activated charcoal granule compositions which, when dry spread and "watered-in" to a site, reduces undesirable biological activity of deleterious organic compounds. When wet, these granules disperse very rapidly with a large dispersion area to original granule diameter ratio. The granules have high loadings of charcoal, i. e. , from about 60 to about 95 weight percent and contain from about 5 to about 40 weight percent of a surfactant system which exhibits excellent dispersing; rewetting; and binding properties.
