Abstract: The present invention relates to a tissue suitable for use in the disinfection of hard surfaces, instruments and human or animal skin or as a sheet inclusion in a washing process for the purpose of disinfection or bleaching. The tissue comprises first and second substrate layers which are bonded together with an adhesive polymer. This polymer also retains solid particles between the layers, which particles, when dampened with a suitable liquid become active and release chlorine. Preferably, the adhesive polymer comprises either a copolyester, copolyamide or polyethylene hot melt adhesive powder or an ethylene vinyl acetate (EVA) or modified EVA hot melt adhesive powder with a particle size between 0 and 750 microns inclusive.
Abstract: An improved tunable citizen band antenna includes an adjustable tuning assembly located at the tip of a wire wound fiberglass core antenna to lengthen or shorten the effective electrical length of the antenna, so that the antenna can be tuned to a specific, desired resonant frequency, resulting in enhanced antenna radiation, reception, and power transmission.
