of the Invention The subject of this invention is a novel polymeric composition useful in membrane technology such as microfiltration, nanofiltration, ultrafiltration, reverse osmosis and gas separation. The composition is formed by taking a known condensation polymer such as polyether sulfone, polysulfone or a polyarylether sulfone and modifying it to change the molecular weight distribution. The...

A combination motor-pump and soil separator (20) assembly includes a reversible motor (17) which drives a wash pump and a drain pump. When operated in a wash mode, the wash pump directs pressurized wash liquid to one or more wash arms (22). In addition, a centrifugally sampled portion of the wash liquid containing a high concentration of entrained soil particles is directed to a guide chamber (52)...
