US Classification:

96134, 96135, 96153, 553852, 55521, 55524, 454354

Abstract:

A filter system including a housing with an intake and an outlet, a pleated carbon filter disposed between the intake and the outlet for filtering out vapors entering the intake, and a hydrophobic solution dispersed about the pleated carbon filter to inhibit adsorption of water thereby increasing the adsorption capacity of the pleated carbon filter especially in high relative humidity environments. The hydrophobic solution is selected so that it does not decrease the adsorption capacity of the carbon filter. Also disclosed is a method of making such a filter.

Abstract:

The present invention provides variable pore size filters. The variable pore size filters of the present invention comprise a fabric matrix, having a set pore size, wherein the fabric matrix is coated with a gel that expands and shrinks in response to a trigger. When the gel is expanded, the pore size of the filter is small and filtering is accomplished. When the gel is shrunken, the pore size of the filter is large and cleaning of the filter by a backwash or forward flush of fluid is accomplished.

US Classification:

427/212000

Abstract:

A method of preparing an anti-fouling coating, the method including the steps of soaking polymeric gel beads in the presence of a solution including a solvent and a biocide to swell the gel beads and absorb both the solvent and the biocide therein, evaporating the solvent, rinsing any biocide of the surface of the beads, and mixing the beads in a coating material.

International Classification:

F23G 5/027

US Classification:

110229

Abstract:

An on-site modular method and system for processing waste typically including food from a food services facility. The waste is processed in a size reduction unit and subsequently dried in a dryer. The dried shredded waste is processed to produce densified pellets. The food binds the non-food waste in the pellets. The pellets are burned in a thermal conversion unit to produce a gas and waste heat. The waste heat is directed to the dryer for use therein. The gas is fed to a generator or turbine to produce electricity. A portion of the electricity produced is used to energize the process.

International Classification:

C10J 3/72

US Classification:

48 87

Abstract:

A gasifier includes a gasification chamber including an annular chamber wall with a top opening for introducing fuel into the gasification chamber. A restricted bottom outlet section of the gasification chamber has inwardly angled wedge walls encouraging a mass flow rather than a funnel-flow of fuel through the gasifier.

US Classification:

252194

Abstract:

A vapor extraction apparatus includes a gel sorbent capable of absorbing vapor directly into the liquid state and capable of disgorging the absorbed liquid in a phase-transition. The apparatus includes a housing adapted for movement from a first position, where it is exposed to a vapor-containing gas stream and a first environmental condition, and capable of moving to a second position, where it is exposed to a second environmental condition. A gel sorbent is disposed on at least one surface of the housing. The gel sorbs vapor from the gas stream as liquid when the sorbent is in its first position. The sorbent disgorges the liquid during phase-transition collapse when it is in the second position. A method of extracting vapor from a process gas stream includes contacting a phase transition gel sorbent with vapor under conditions sufficient for the gel sorbent to undergo a phase transition and absorb vapor as liquid inside the gel sorbent. The gel sorbent is then exposed to conditions sufficient for it to undergo a phase transition and disgorge the liquid from inside the gel sorbent.

Abstract:

A transverse flow, self-heating electrically conductive sorption system for separating species of different adsorption characteristics in a fluid includes a containment vessel, an electrically conductive permeable sorbent bed having a multiplicity of adsorption sites in said vessel; a porting structure for supplying contaminated fluid in a first direction at one surface of the bed and for receiving the contaminated fluid at another surface of the bed; and a pair of spaced electrodes for applying current through the bed in a second direction transverse to the first direction to self-heat the electrically conductive sorbent bed.
