Abstract: SHAPED POLYETHYLENE ARTICLES OF INTERMEDIATE      MOLECULAR WEIGHT AND HIGH MODULUS                        ABSTRACT Solutions of intermediate molecular weight polymers from about 200,000 to about 4,000,000, such as polyethy-lene, in a relatively non-volatile solvent are extruded through an aperature at constant concentration and thereafter stretched at a ratio of at least about 3:1 prior to cooling to form a first gel.  The first gels are extracted with a volatile solvent to form a second gel, and the second gel is dried to form a low porosity xerogel.  Stretching occurs with any one or more of the first gel, second gel or xerogel.  The polyethylene products produced by our process include products having a molecular weight between about 200,000 and about 4,000,000 a tenacity of at least about 13 grams/denier, a modulus of at least about 350 gram/denier, a porosity of less than 10% by volume, a crystalline orientation function of at least about 0.95, and a main melting temperature of at least about 140°C.

Abstract: ABSTRACT OF THE DISCLOSURE           A treating process is shown for removing cloggants from the pores and surfaces of aeration diffuser elements used in an activated sludge treatment process or the like.  In this process, an acid gas is fed to the plenum chambers that support the respective elements to be treated, and water is permitted to flow from the sludge mass through the diffusers into the plenums to form the desired acid solution for reacting with the cloggants to be removed.  The process is performed so that the acid solution fills the pores and contacts the surfaces of the diffusers and the plenums and the submerged piping network and the acid solution is then agitated in contact with the diffusers to react with the cloggants in the pores and on the surfaces of the diffusers to rejuvenate these elements.  In another embodiment of the process, an acid solution is made to fill the aeration piping network, is fed through the plenum chambers that support the respective elements to be treated, and into the pores in said elements for reacting with the cloggants to be removed.
