A lower end of the cover has an arcuate nose disposed substantially above the outer edge of the gutter. The surface of the gutter is treated with one or more combinations of coatings and/or substrate textures to slow the flow of water while improving flow to the cover surface. Rainwater will flow around the arcuate nose into the gutter while debris carried by the rainwater is expelled outwardly over the edge of the gutter.

Method of reducing material size

The present invention relates to a method of reducing particle size by the use of a supercritical fluid, generally carbon dioxide. The material is swollen by the supercritical carbon dioxide at a high pressure. After the material has been allowed to swell under a high pressure, the pressure is rapidly dropped. When the external pressure is rapidly dropped, the material explodes as the supercritical gas absorbed into the material rapidly expands outward.

Particle size reduction using supercritical materials

The present invention relates to a method of reducing particle size by the use of a supercritical gas, such as carbon dioxide or a refrigerant. The material is swollen by the supercritical gas at a high pressure. After the material has been allowed to swell under a high pressure, the pressure is rapidly dropped. When the external pressure is rapidly dropped, the material explodes as the supercritical gas absorbed into the material rapidly expands outward.
