    摘要: A point-of-use membrane filtration system and method for water or other liquids including an automatic control system for purge, rinse-up, sanitization, or combinations thereof. The system may be used for microfiltration, ultrafiltration or hyperfiltration (reverse osmosis) depending on the membrane pore size of the filtration cartridge employed in the system. A reject valve at the bottom of the filter cartridge is automatically opened when filtered product is drawn, thus to direct some water and any waste to drain. The control system is programmed to accomplish purge, rinse-up and sanitization procedures at predetermined intervals with predetermined combinations of procedures.

    摘要: A system and method for depositing a pattern of media on a moving surface includes a media depositing apparatus that deposits media in a predefined pattern on the moving surface. A media applicator roll having a media receiving region, such as engraved or raised portions, receives the media from a media feeder as the media applicator roll rotates. A media retaining member maintains the media in contact with the media receiving region until the media reach a bottom region of the media applicator roll and are released from the media applicator roll in the predefined pattern onto the moving surface. The method for depositing a pattern of media includes synchronizing the speed of rotation of the media applicator roll with the speed of the moving sheet of material so that the media are precisely deposited as they are released from the media receiving region. The method also includes minimizing the distance that the media must drop from the applicator roll receiving region to the moving surface.

    摘要: A weatherproofing membrane having a high traction surface is used on a roof or other such location to prevent individuals from slipping. The weatherproofing membrane includes a facer sheet formed of a weatherproofing material and one or more polymer regions disposed on an upper side of the facer sheet. The weatherproofing membrane also includes a layer of modified asphalt disposed on the lower side of the facer sheet and a release backing disposed over the modified asphalt. The polymer is softer than the weatherproofing material and thus provides a higher traction surface than the weatherproofing material of the facer sheet. The polymer includes a low molecular weight polyethylene and an amorphous polyolefin (APO) in respective proportions ranging from about 50/50 to 90/10. The low molecular weight polyethylene and the APO are mixed hot and applied to the facer sheet, for example, using conventional coating techniques.

    摘要: An asphalt roofing material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill, to reduce the asphalt material granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled, either during heating and milling by continuously venting the heated milling apparatus, or before the heating and milling in a drying apparatus. The heated milling apparatus preferably includes a rotatable milling vessel rotated at an acute angle with respect to the horizontal plane and having an opening that provides continuous venting. The rotatable milling vessel includes a plurality of mixing members, such as rods or paddles, extending from an interior surface and preferably arranged in a helical pattern to force the asphalt material away from the opening. The asphalt material recycling system further includes a storage apparatus for storing reduced asphalt material and a filter apparatus for filtering reduced asphalt and removing foreign objects therefrom.
