摘要:
A filter element for an air filter assembly of an engine including a breather conduit and an intake conduit, comprising filter media having a closed loop, the filter media having a top and bottom; a first wall provided on the top of the filter media, the first wall having no openings; and a second wall provided on the bottom of the filter media, the second wall having two separate openings; wherein the filter media, the first wall, and the second wall define an interior chamber of the filter element, and wherein the two openings connect to the interior chamber such that air filtered by the filter media mixes with unfiltered gases provided through a first of the two openings by the breather conduit prior to exiting the interior chamber through a second of the two openings into the intake conduit.

A system for collecting matter provides a low energy, low cost and nearly zero pollutant process for extracting suspended and/or dissolved matter in a medium. The system collects the matter on a material which is deployed into the medium, and the matter is extracted off the material. If the extracted matter is algae, then it can be processed into end user commercial products such as pharmaceuticals, nutraceuticals, cosmetics, biofuels, food products, crop fertilizer, animal feed and polymers. If the extracted matter is oil or bitumen, then it can be recovered at oil spills or in tar sands. If the medium is infected with a harmful algae bloom of cyanobacteria, then the system could not only harvest the algae for processing but also cut off a food source of remaining algae by additionally extracting suspended silt. This invention collects matter in an economically and environmentally viable manner.

The present invention provides a multi-functional nonwoven fabric for filter that has excellent properties to adsorb various toxic/harmful substances such as odorous substances, VOCs, allergens, and pathogenic viruses, has antibacterial/antimold properties, and suppresses pressure loss to a minimal level, and the present invention also provides a method that can produce such a nonwoven fabric in a simple manner. Due to the simple steps of immersing the nonwoven fabric in an aqueous polypeptide solution and further treating it with a metal salt, it is possible to obtain a nonwoven fabric for filter having excellent adsorption properties in which the fiber surface of the nonwoven fabric is coated with insolubilized polypeptide that has been crosslinked with a metal. Also, a method that can produce such a filter in a simple manner was found.

摘要:
[Problem to be Solved] A sheet made of a fabric or paper coated with a substance which has a strong function to adsorb, remove and make harmless microbes such as bacteria and viruses is to be configured so as to be usable as a filter, a mask or the like capable of removing the microbes such as the bacteria and viruses. [Solving Means] A sheet made of a fabric which uses a fibrous material, for example, polyester in which a sulfenate group or a carboxylate group has been introduced, and has a surface coated, for example, with anatase type titanium oxide makes microbes such as bacteria and viruses harmless by adsorbing these microbes and has sufficient air permeability, therefore being usable as a filter, a mask or the like. Furthermore, a sheet made of a fabric or paper which is impregnated with an aqueous solution of polyvinyl alcohol copolymerized with a monomer having a sulfonate group or carboxylate group as a fabric size and on which titanium oxide is coated and fixed has a function to make harmful microbes harmless by adsorbing these microbes, therefore being usable not only as a filter or a mask but also as fruit packing material or the like.
摘要:
The invention relates to a filter bag for a vacuum cleaner. Said filter bag is made of a composite material encompassing at least three layers. At least two layers, which are composed of a fleece layer and at least one fiber fleece layer, are connected by means of a welded joint. The invention further relates to the use of such a filter bag.
摘要:
It is intended to provide an air purification filter which has a high dry tensile strength, a high wet tensile strength in association with a high water resistance and a high water repellency and exhibits a bactericidal effect due to a gas phase reaction in a gas phase. Namely, an air purification filter having a high dry tensile strength, a high wet tensile strength (a high water resistance) and a high water repellency as well as a bactericidal effect which is obtained by blending a filter fiber having a functional group with a mixture of a modification enzyme which has an ionic polarity opposite to the ionic polarity of the whole filter fiber as described above and a bactericidal effect with an ionic synthetic resin binder having the opposite ionic polarity similar to the modification enzyme.
