    摘要: Apparatus and method for attenuating fluid foil tip vortices, featuring a "Coanda tip" and a "Coanda curtain." The fluid foil tip has a Coanda surface and means for discharging compressed fluid adjacent thereto; a resultant fluid barrier is formed generally chordwise and perpendicular to the fluid foil plane and tangential to the fluid foil tip upon Coanda entrainment and deflection of the discharged compressed fluid. The fluid barrier prevents crossflow from the higher pressure fluid region to the lower pressure fluid region, the fluid regions being separated by the fluid foil when moving relatively through a fluid, the fluid barrier thereby stemming tip vortex generation at its source.

    摘要: A radial or azmuthal non-resonant flow-through optoacoustic cell is operated without windows, completely eliminating the window background interference. The cell is constructed of an elongated tube the length of which is 34.times.10.sup.3 cm.times.1/f, where f is the light source modulating frequency and is made of conducting material which is perforated along the center one-half length with holes. A metalized sheath surrounds this center region to form a capacitor microphone.

    摘要: A polphthalocyanine with the structure formula: ##STR1## prepared by mixing SnCl.sub.2.2H.sub.2 O with N, N'-bis(3,4-dicyanophenyecane diamide of which the structural formula is: ##STR2## heating the mixture to a temperature from about 175.degree. C. to about 185.degree. C. for about 15 to 20 minutes to form a resin; and curing the resin at a temperature from about 190.degree. C. to about 230.degree. C. The polyphthalocyanine is useful as an adhesive, as a matrix for glass or carbon-fiber reinforced composites, and as structural material.
