The present invention utilizes the method of producing a negative-pressure source in the outlet of wind turbine to concentralize wind energy for use. An ejector ora cyclone is used as the negative-pressure, and a wind channel is used for producing a higher pressure difference between the inlet and the outlet of the wind turbine, thus, to increase the efficiency of the wind turbogenerator. Furtherm...

Energy efficient process and apparatus are disclosed for forming glass fiber packages which are free of migration. Air from around the fiber forming bushing is passed beneath the bushing whereby it is heated by bushing heat and the heated air is then drawn into a chamber through which the glass fibers pass in heat transfer contact with the heated air. This heat transfer contact causes the water or...

The removal of sticky contaminants and/or ink particles during the production of recycled paper is accomplished utilizing a hydrocyclone (31) froth flotation process.
