Abstract: An odor adsorbing pet pad includes an adsorbent mat with a nonwoven hydrophobic fabric; and a bio-enzymatic odor reducer with bacillus in spore form which is applied to the adsorbent mat. In particular, the bacillus in the bio-enzymatic odor reducer is activated when animal waste interacts with the adsorbent mat of the odor adsorbing pet pad.

Abstract: A downhole assembly includes a float tool configured to be connected to a casing string and including one or more one-way valves configured to permit fluid flow in a downhole direction and to prevent fluid flow in an uphole direction, and a first wiper plug configured to be deployed into a well via the casing string and engage the float tool. The first wiper plug comprises a valve element that is configured to prevent fluid flow through the first wiper plug at least in the uphole direction.

Abstract: A downhole valve includes a housing, and a sleeve positioned within the housing. The sleeve has a first axial end, a second axial end, and a seat positioned between the first and second ends. The sleeve defines an opening facing in a radial direction. The sleeve prevents fluid flow in an opposite radial direction, away from the opening. The valve also includes a retaining element coupled to or integral with the sleeve, and a first obstructing member positioned in the sleeve and movable between the seat and the retaining element. In a first position, the first obstructing member engages the seat and prevents fluid flow through the housing. In a second position, the first obstructing member is separated apart from the seat such that at least a portion of the opening is axially between the first obstructing member and the first obstructing member.

Abstract: A composition including a blend of rechargeable biospheres and water, and optionally bacteria, biological and/or chemical reagents, wherein the biospheres are cellulosic and/or starch based biopolymers and have a free swell absorption capacity, wherein the composition is formable into an environmentally responsive gelatinous matrix which delivers and sustains bacteria, biological and/or chemical reagents in situ.

Abstract: A composition is provided including biospheres and bacteria, wherein the biospheres are cellulosic biopolymers and sized in the range from 500 nanometers to 80 microns and have a minimum free swell absorption capacity of 400 times by weight and a maximum free swell absorption capacity of 1200 times by weight, wherein the composition is formable as a gelatinous matrix.

Abstract: A resin reinforced fibre product such as glass fibre impregnated with a thermosetting resin is treated to recover fibre by initially shredding the waste, pulverizing the shredded waste and sieving the pulverized waste to separate the free fibres. The remaining waste is milled to produce a fine powder suitable as a filler. The pulverizing is completed without classification and a portion of the pulverized product above a nominal cut size recampaigned. Free fibres are separated by an airlift during the sieving process.
