Abstract: A biodegradable, non-pressure compression leg wrap for cattle suffering lameness from for example digital dermatitis with disintegration time controlled by the ratio of polyvinyl alcohol to copolymer starch or cellulose in the wrap composition.

Abstract: A device (10) for testing samples of aviation fuel drained through a drain valve of an aircraft fuel system is disclosed including a pin (22) upstanding from the bottom (18) and extending concentrically with the sidewall (16) out of and above the inlet (20) of a container (12). Thus, the fuel draining from the drain valve is caught and collected by the inlet (20) and is contained in the container (12) for visual observation for particulate contamination and liquid separation. Device (10) further includes specific gravity floats (32, 34) having densities to float in water but not in jet fuel and gasoline and to float in water and jet fuel but not in gasoline, respectively. Thus, by observing the condition of the floats (32, 34), the pilot can quickly, accurately, and clearly determine whether the sample is gasoline, jet fuel, or water.

Abstract: A method and apparatus for microencapsulating an electroluminescent phosphor with an extremely thin coating. The process involves vaporizing a poly-para-xylylene, pyrolyzing the resulting vapors to form reactive monomeric radicals, and then passing such vaporous radicals to a vacuum deposition zone where they contact tumbling particles of an electroluminescent phosphor under vacuum conditions. As the particles are being coated, they are sifted by means of a screen. The reactive monomeric radicals deposit on the tumbling particles, are adsorbed by the particles, and polymerized into a very thin coating on the surfaces of the particles.
