Abstract: The wall of the friction spinning element has bores or holes with a predeterminate bore diameter and a coating on their side facing a fiber feed duct, the coating extending over the bore edges into the bores.

Abstract: Disclosed is a self-contained, rapid cooling device that can be stored for indefinite periods without losing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber.

Abstract: An array of sensors responsive to atmospheric electrostatic fields is deployed, preferably with the sensors elevated above the ground. Suitable sensors are corona point sensors having a stainless steel needle. The corona current signals from the sensors are digitized and processed to determine the peak in the rate of sharp discontinuities in the electrostatic field. The peak in the rate of sharp discontinuities precedes a thunderstorm microburst by several minutes. The signal processing apparatus also generates equipotential contour maps of electrostatic field for spatially locating a microburst. The latter signal may also serve as a predictor for windshear since anomalous electric fields caused by charge carrying downdrafts may occur without lightning.
