Abstract: The invention is directed to a microbiological interception enhanced filter medium, preferably having an adsorbent prefilter located upstream from the filter medium. Preferably, the prefilter is adapted to remove natural organic matter in an influent prior to the influent contacting the microbiological interception enhanced filter medium, thereby preventing loss of charge on the filter medium. The microbiological interception enhanced filter medium is most preferably comprised of fibrillated cellulose fibers, in particular, lyocell fibers. At least a portion of the surface of the at least some of the fibers have formed thereon a microbiological interception enhancing agent comprising a cationic metal complex. A filter medium of the present invention provides greater than about 4 log viral interception, and greater than about 6 log bacterial interception.
Abstract: The artificial firelogs of this invention provide a natural visual and audible sensation so that the artificial firelogs have both a soothing flickering flame and a crackling or popping sound normally observed only with natural wood logs. The crackling additive can be mustard seeds, sesame seeds and synthetic hollow spheres.

Abstract: The instant invention generally relates to absorbents containing effective odor absorbing amounts of activated carbon. The activated carbon-containing absorbents may also be formed in conjunction with a wide variety of adsorbent materials including bentonite, opaline silica and the like and are suitable for use as absorbents in a wide variety of absorbent application and are particularly well suited for use as animal litters. Such absorbent may also contain fluoropolymer dedusting agents and bactericides to form unique absorbent compositions with diverse properties and uses.

Abstract: A disposable pet litter basin is disclosed. The basin includes a bottom and a first sidewall which forms the container for animal litter and a second sidewall spaced apart from the first sidewall by a plateau and trough. The plateau and trough increase the basin's ability to resist spillage of litter by providing increased strength and stability and by providing an area to receive spillage from the container for animal litter which is inside the litter basin. Further, the basin has an anti-tipping feature to stabilize the basin during use.
Abstract: A closure device providing tactile confirmation of occlusion is disclosed. The closure device comprises first and second interlocking fastening strips arranged to be interlocked over a predetermined length, at least one of the fastening strips having a deformation in the closure device after occlusion of the closure device. This deformation allows a user to tactually confirm that the closure device has been occluded, even after the closure device has been occluded. The deformation may be an inward deformation or an outward deformation on the fastening strip. The deformation may be on one or both of the fastening strips. The fastening strip may include multiple deformations. The deformation may be facilitated by providing a flexure point in the fastening strip, such as, an area of reduced cross-section or a coextruded portion with a different modulus of elasticity. In one embodiment of the invention, the fastening strips include mateable male and female closure elements.
Abstract: The instant invention generally relates to absorbents formed from compacting bentonite-containing materials containing an effective amount of the bentonite particles of a size under 100 U.S. mesh.
Abstract: The instant invention generally relates to absorbents formed from compacting bentonite-containing materials containing an effective amount of the bentonite particles of a size under 100 U.S. mesh. The absorbent is compacted under effective compacting pressures to form a bentonite material suitable for use as an absorbent and is characterized as having lower costs, increased absorbency over similarly sized and compositionally similar non-compacted bentonite-containing materials and/or improved clump strength when used as an absorbent.
Abstract: An aqueous polymer preservative and protectant composition containing a silicone emulsion, an aminofunctional silicone emulsion, a film forming thickening agent and a polyol.

Abstract: The present invention features a high-speed registration system for the manufacture of plastic bags. The system has a registration apparatus that senses the leading and trailing edge of each sinusoidally-shaped tie pattern from a continuous web. Each sinusoidally-shaped tie is associated with an individual bag entity and, therefore, represents a midway point for each bag to be cut from the continuous web. The leading and trailing edge of each sinusoidally-shaped tie, therefore, is used to determine the center line of each bag. A plurality of center line determinations are averaged upstream of the sizing apparatus.
Abstract: The process relates to the reinhibition of recycled antifreeze/coolant. The process is particularly well suited for use with recycled, used antifreeze/coolant from the cooling systems of internal combustion engines.

Abstract: A multi-component polish composition and polishing process for a surface. The polish composition comprises a multi-component mixture which when applied to a surface, e.g., the painted surface of a vehicle, under effective drying conditions forms a substantially dry hydrophilic wax-containing film which may be substantially removed from the surface by water rinsing of the surface whereby a hydrophobic protective layer is provided to the surface.

Abstract: The invention relates to a write-on surface derived by surface treatment (corona-discharge or other similar surface treatment) of a novel write-on composition. The write-on composition to be treated is characterized as a physical mixture of two substantially incompatible polymers and, optionally, a particulate material.
