Our analysis of this patent is as follows:

Natural Earth Technologies, Inc.’s patent US 5409166 A deals with Battery-powered particulate spreader.
A portable electric-powered particulate spreader has a housing having an inlet and an outlet. A reservoir holds particulate material located on the housing. A blower located in a flow path from the inlet to outlet to induce air flow along the flow path. A clean intake ports formed in a channel wall containing an exhaust channel came down from the blower outlet. A valve controls flow of particulate material from the reservoir to the intake port unclean. Misleading located between the reservoir and exhaust channel rotationally retaliate and accelerate the formulation vibrations that help the flow of particulate material. A foil exhaust channel a low static pressure which tends to draw particulate material from the reservoir to the air flow. Delays built so that the blower turns before the opening of the valve which opened and closed the valve before the blower is turned on.

The Rhone-Poulenc Inc. patent solves the following problem:

This invention relates to the manufacture of uniform glass fiber mat of wet-laid process, and particularly, it is concerned that more glass fiber dispersion composition for use as a process.

Our analysis of this patent is as follows:

Rhone-Poulenc Inc.’s patent US 5409574 A deals with Propoxylated fatty amine ethoxylate surfactants as glass fiber dispersants for the manufacture of uniform glass fiber mats.
According to the present invention, there is provided in developed glass fiber dispersions in making uniform glass fiber mat of wet-laid process. The well dispersed glass fiber compositions to create this usually prepared by mixing chopped glass fiber bundles in the water with a small amount of a propoxylated fat wet ethoxylate surfactant to disperse the bundles of individual fibers. As a part of the invention, the dispersions can be formed at relatively high glass fiber consistencies. The resulting dispersions are characterized by lower mouth and can be used to make very high quality glass fiber mat at high production rates.
