Abstract: A system for generating sterile water is provided, including: a liquid holding container having thereon a container outlet; a filtration device including therein a low-pressure-differential pathogen filtration portion, wherein the filtration device has a filtration inlet and a filtration outlet; and a gas tube; wherein the container outlet is connected to the filtration inlet; wherein the filtration inlet has a gas hole with one end connected to the gas hole and the other end having a buoy; wherein the sterile water is substantially pathogen-free.

Abstract: An embossed porous membrane wipe and/or a method of making and/or using such embossed microporous membrane wipe. The preferred embossed microporous membrane wipe includes a microporous membrane embossed alone or with a polypropylene nonwoven. The nonwoven may be a spunbond, meltblown, and/or electrospun nonwoven. The microporous membrane may include a biaxially oriented microporous membrane. The biaxially oriented microporous membrane may be made from one or more block copolymers of polyethylene and/or polypropylene. A method of using such an embossed microporous membrane, composite or laminate wipe for skin oil blotting is also provided.

Abstract: A circulating filter and aerator system is to be installed in a pond of an aquaculture system and includes a pump unit which draws water from the pond and which is adapted to float and extend into the pond at a desired depth, a filter unit with an inlet port and an outlet port, a first control valve which connects the pump unit and the inlet port of the filter unit and which controls water flow from the pump unit to the filter unit, a floating aerator unit which receives filtered water from the filter unit and which generates sprays of the filtered water to release harmful gas and to reintroduce oxygen into the pond, serially connected second and third control valves which connect the outlet port of the filter unit and the floating aerator unit and which control water flow from the filter unit to the floating aerator unit, a fourth control valve which is provided on the filter unit to permit release of air in the filter unit when water fills the filter unit, a fifth control valve which is provided between the

Abstract: A spray spinning collection unit includes a cylindrical collection mandrel and a cooperating press roll. The cooperating press roll has a peripheral surface disposed adjacent to a cylindrical surface of the mandrel so as to define a gap therebetween. To provide a predetermined radial density gradient in a cylindrical nonwoven product formed by the gap between the press roll and the mandrel, the gap has a varying height defined by the contour of the peripheral surface. The contour is selected to give the predetermined radial density gradient. Portions of the peripheral surface of the press roll may be either convex, concave, or both.

Abstract: A spray spinning nozzle for producing a substantially continuous filament from a molten synthetic resinous material includes a nozzle with a removable orifice from which a filament of molten material is emitted and a gas attenuation assembly which is laterally removable from the nozzle. The attenuation assembly includes at least three gas jets spaced about and radially close to the nozzle axis for emitting high velocity jets which converge upon and contact the filament at a point along the axis in front of the orifice. Drag forces produced by the gas jets attenuate the filament to a thin diameter.

Abstract: A spray spinning nozzle for producing a substantially continuous filament from a molten synthetic resinous material includes a nozzle with an orifice from which a filament of molten material is emitted and a gas attenuation assembly which slides axially over the nozzle. The attenuation assembly includes at least three gas jets spaced about and radially close to the nozzle axis for emitting high velocity jets which converge upon and contact the filament at a point along the nozzle axis in front of an orifice. Drag forces produced by the gas stream attenuate the filament to a thin diameter. The nozzle includes a plurality of circumferentially spaced recesses which cooperate with corresponding recesses and projections of the attenuation gas assembly to accommodate heater means and to provide mounting means.
