摘要： A separator for use in installations for conveying objects over distances by means of a flow of air, the separator including a generally cylindrical separator grid within a casing, and a spiral grid portion extending outside the cylindrical grid. The spiral grid portion is tangential to said cylindrical grid and to the outside wall of an inlet pipe for admitting a mixture of air and objects. The cylindrical grid and the spiral grid portions permit the passage of air, but not the objects. An adjustable flap is pivoted on the line of intersection between the inside wall of the inlet pipe and said cylindrical grid for controlling the flow of air and objects entering the separator. The spiral grid portion has a rough surface exposed to the gas flow.

摘要： The present invention relates to an asymmetric gaseous permeation membrane, also applicable to fractionation of a gaseous mixture and in particular dehydration and deacidification of gases, in particular gaseous hydrocarbons, and obtained from polymers of the polyquinoxaline family presenting the unit: ##STR1## and R=H or phenyl radicalG=carbon-carbon bond, or --O--, --S--, --SO.sub.2 --, --CO-- ##STR2## presenting a dense "skin" of low thickness of 0.05 to a few microns substantially without defects to permit gas molecules to pass through by a dissolution-diffusion mechanism.
摘要翻译：本发明涉及不对称气体渗透膜，其也适用于气体混合物的分馏，特别是气体脱气和脱酸，特别是气态烃，并且由提供该单元的聚喹喔啉族的聚合物获得：＆lt; IMAGE＆gt; n = 10，R = H或苯基G =碳 - 碳键，或-O-，-S-，-SO 2 - ， - CO- + TR 基本上没有缺陷的0.05至几微米的低厚度的致密“皮肤”，以允许气体分子通过溶解扩散机制通过。
