    摘要： A pleated paper filter element is disclosed which is formed from a mechanically-treated filter paper (10') which has the side thereof opposite to the wire-side (12) mechanically teased so as to form thereon an open, textured layer (18) of raised fibers. The starting material used is a standard, commercially-available filter paper which is resin-impregnated with an uncured phenolic resin. The pleated paper filter element formed from the treated filter paper (10') displays, after the element has been heated to cure the resin, a substantial increase of up to 73.5% in the dust-holding capacity over a like element formed from the standard, commercially-available filter paper.

    摘要： The present invention is directed to a method of removing metallic hydroxide salts having impurities from an aqueous medium. The method includes the steps of:(a) providing an edge type filter;(b) passing an aqueous medium with metallic hydroxide salts having impurities to the filter;(c) removing the metallic hydroxide salts with the filter and forming a cleaned aqueous medium;(d) removing the cleaned aqueous medium from the filter;(e) drying the filter after the filter has become blocked by the metallic hydroxide salts and forming a powder; and(f) removing the powder from the filter, whereby the filter is unblocked.

    摘要： A hot-extraction paper consisting substantially of cellulose and manufacturing assistants needed in cellulose and manufacturing assistants needs in cellulose production, such as pH modifiers based on acids and/or bases, the paper comprises exclusively cellulose having fibre lengths of at least 2.0 mm on length-weighted average, more particularly at least 2.5 mm on length-weighted average, and has isotropic extension properties which are substantially equal in machine and cross directions and amount to at least 7.5%, more particularly at least 8.5%.
