摘要:
A gel-forming composition is used in a process for molding a ceramic composition. The gel-forming composition, such as agar, is improved with a gel-enhancing agent, e.g. polyethyleneimine. As a result, the gel-forming composition improves the ceramic molding process and/or the ceramic product formed therefrom.

An improved oil filter, for use with an internal combustion engine, comprises a hollow filter housing defining a chamber therein and having an inlet and an outlet with a flow path therebetween; a mechanically active filter member disposed inside the filter housing in the flow path; and a chemically active filter member disposed inside the filter housing in the flow path. The chemically active filter member comprises a plurality of composite oil additive pellets. The plurality of pellets is interconnected to form a substantially integral permeable member, and the substantially integral permeable member is impregnated with an alkaline composition. The alkaline composition is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine.

An evaporative emissions filter for an engine air induction system. The evaporative emissions filter includes a hydrocarbon vapor-adsorbent member disposed within the air induction system outside the direct air flow path. A mechanism is provided for mounting the evaporative emissions filter within the air induction system. Hydrocarbon vapors present in the air induction system after engine shut-down are substantially retained in the adsorbent member until air flows through the air induction system after the engine starts.
摘要:
Modification, neutralization and/or decontamination of airborne biological and/or chemical contaminants from a breathable atmosphere by subjecting the breathable atmosphere to a filter which is formed from a plurality of polymeric multilobal fibers. These fibers include a central core with T-shaped lobes projecting therefrom, wherein each T-shaped lobe has a leg and a cap. The lobes define a longitudinally extending internal cavity between two adjacent legs that extends the entire length of the fiber. The filter is impregnated with a biological and/or chemical decontamination reagent for chemically modifying, neutralizing and/or decontaminating airborne biological and/or chemical contaminants from a breathable atmosphere. A filter projection preferably extends into an external reservoir containing a supply of biological and/or chemical decontamination reagent. This configuration increases the capacity and efficiency of the filter, and causes a lower pressure differential across the filter.
