Abstract: Golf ball comprising one or more layers and/or indicia formed from a fluorescent composition comprising: a base polymer; and a colorant; wherein the colorant is a small-molecule ionic isolation lattice formed from one or more fluorescent dye and one or more cyanostar macrocycles. The one or more fluorescent dyes may include at least one dye selected from xanthenes, oxazines, styryls, cyanines, trianguleniums, or mixtures thereof. The colorant may be a dispersion of the small-molecule ionic isolation lattice in a carrier medium or a powder. In particular embodiments, at least one of the one or more layers is a cover layer and/or a coating layer.

Abstract: A gas turbine engine control for regulating bleed from a compressor which has an engine performance map that is compressor stall stable when the ambient inlet air temperature of the engine exceeds a predetermined level and including a compressor bleed valve having a servo controlled pressure diaphragm operated poppet valve therein that is operative to bleed valve from the compressor in accordance with compressor discharge pressure conditions to extend the stall limits of operation of the compressor during engine start and low power or ground idle operation and wherein the bleed valve is associated with a thermally responsive solenoid valve controlled by a thermal switch responsive to ambient inlet air and supported on the inlet of the compressor at a point beyond the influence of engine generated heat for imposing an override pressure on the bleed valve to hold it in a closed position to prevent engine compressor bleed thereby to avoid engine power depreciation at ambient inlet air temperatures above the pred
