Abstract: The present invention relates to an air cleaner element holding structure for an air cleaner device for use in filtering intake air for an engine. The air cleaner device includes an air cleaner element and an element holder, provided in an air cleaner case. The air cleaner element includes at least a pair of element support plates and the element holder includes at least a pair of circular plates. The air cleaner case includes an intake duct facing an inner circumferential side of the air cleaner element for conducting air thereto. Each of the support plates has an outer diameter that is larger than that of the air cleaner element. The element support plates support the air cleaner element in such a manner that both ends, in the axial direction, of the element holder contact an inside surface, in the axial direction, of the element support plates.
Abstract: To improve in pulse cleaning of filters, a filter element includes a media pack of Z-media having first and second opposite flow faces and a side wall extending between the first and second flow face. A gasket is secured to the side wall. The gasket has a sealing portion and an attachment portion. The sealing portion has a flat surface at least one inch long and is located between being planar with and 0.5 inches recessed from the first flow face, inclusive.
Abstract: A fabric filter bag (50) and cage (10) system for use in a bag house (66) for industrial process gas stream particulate removal. The bag house (66) includes an inlet (68) for process gas flow into an interior space (65) thereof, at least one fabric filter bag (50) and cage (10) system within the interior space (65) for filtering the process gas as it flows therethrough, and an outlet (70) for flow of cleaned process gas out of the interior space (65) of the system. The subject fabric filter bag (50) and cage (10) system provides about an additional 14% filter material per bag as compared to like sized round filter bags, thereby effectively reducing the size of bag house (66) required to achieve a particular air to cloth (A/C) ratio. Reducing the size of the bag house (66) required to achieve a particular A/C ratio significantly reduces capital costs typically associated therewith.
Abstract: A process for the separation of the aromatic compounds benzene, toluene and xylene from an aromatics-containing reformate gasoline and pyrolysis gasoline or a coke-oven light oil or an aromatics-containing refinery stream, in which the aromatics are separated by an extractive distillation uses a novel solvent combination made up of the compounds n,n?-diformyl piperazine or 2,2?-bis-(cyanoethyl)ether in a combination with n-formyl morpholine as a second solvent for extractive distillation so that the solvent combination obtained shows a higher selectivity with regard to the aromatics to be extracted so that a lower solvent load is required. The aromatics-containing feed mixture is first submitted to a pre-distillation so that the obtained fraction has a narrow boiling point range. This fraction is then submitted to an extractive distillation in a first column, in which an aromatics-lean head product of predominantly paraffinic hydrocarbons is obtained as well as an aromatics-enriched bottom product.

Abstract: An objective of the invention is to obtain a cleaning unit which allows a cleaning mechanism, such as a dust removal device, for an air filter to be easily mounted in an indoor unit of an air conditioner that has an air filter on the intake side of an indoor fan. The cleaning unit includes: a chamber casing (101) connected to a room side of an indoor main unit (10) having an indoor heat exchanger (22) and an indoor fan (21) which draws air from the room and blows the air to the indoor heat exchanger (22); an air filter (30) provided in the chamber casing (101) on an intake side of the indoor fan (21); and a dust removal device (50) configured to remove dust captured by the air filter (30).
Abstract: In an indoor unit of an air conditioner including an air filter arranged on a suction side of an indoor fan, dust trapped on the air filter is reliably and efficiently removed by a simple structure. For that purpose, an indoor unit (13) is provided with a dust remover (50) for removing dust trapped on an air filter (40) arranged on a suction side of an indoor fan (39), and a filter presser (70) for pressing a frame (42) of the air filter (40) so as to press the air filter (40) against the dust remover (50). The air filter (40) is configured to move relative to the dust remover (50), and the filter presser (70).
Abstract: An air filter (30) intermittently rotates by a predetermined rotation angle at each time, while being in contact with a bristle portion (51b) of a rotating brush (51). Accordingly, dust on the air filter (30) is scraped by the bristle portion (51b). The brush member (51) rotates about an axial center of a shaft (51a) at each stop of the intermittent rotation of the air filter (30), to come into contact with a cleaning brush member (52). According, dust on the brush member (51) is removed by the cleaning brush member (52).
Abstract: A method of dehydrating tolylenediamine which includes subjecting tolylenediamine having a water content of 5-40 wt. % to first-stage distillation at a vacuum of 13-101.3 kPa and subjecting the bottoms from the first-stage distillation to second-stage distillation at a vacuum lower than 13kPa.
Abstract: An upper endcap of a fuel filter cartridge includes a skirt, an axially extending pin surrounded by the skirt, and a plurality of ribs that define fluid flow channels leading to the pin. The pin is extendable through an axially facing fuel inlet opening at the upper end of a standpipe for actuating a valve to an open position allowing fuel to flow through the axially facing inlet opening and into the standpipe. The valve can include a hole that receives the pin therein to help stabilize the valve when the valve is actuated open.

Abstract: An absorbent liquid according to the present invention is an absorbent liquid for absorbing CO2 or H2S or both from gas, in which the absorbent liquid includes an alkanolamine as a first compound component, and a second component including a nitrogen-containing compound having in a molecule thereof two members or more selected from a primary nitrogen, a secondary nitrogen, and a tertiary nitrogen or a nitrogen-containing compound having in a molecule thereof all of primary, secondary, and tertiary nitrogens. The absorbent liquid has an excellent absorption capacity performance and an excellent absorption reaction heat performance, as compared to an aqueous solution containing solely an alkanolamine and a nitrogen-containing compound in the same concentration in terms of wt %, and can recover CO2 or H2S or both from gas with smaller energy.

Abstract: A pleated filter is made from a monocomponent monolayer nonwoven web of continuous monocomponent meltspun partially crystalline and partially amorphous oriented fibers of the same polymeric composition that are bonded to form a coherent and handleable web having a Gurley Stiffness of at least 100 mg and which further may be softened while retaining orientation and fiber structure. Rows of pleats are formed in the nonwoven web, and the web is cut to a desired size and shape to provide a pleated filter element containing a self-supporting porous monocomponent monolayer matrix of fibers bonded to one another at least some points of fiber intersection and having an average initial submicron efficiency of at least 15% at a 1.52 meters/sec face velocity. The filter element is deformation resistant without requiring stiffening layers, bicomponent fibers, adhesive or other reinforcement in the filter media layer.

Abstract: Disclosed are fibrous activated materials that can remove and/or deactivate potentially dangerous airborne agents from a gas or air stream. Disclosed materials are multi-layer materials that include a fibrous nonwoven interceptor layer and an active layer immediately adjacent the interceptor layer. The interceptor layer is a fibrous membrane of very low basis weight and defines a relatively low porosity, and the active layer describes geometries, chemistries, etc. that can entrap and/or decontaminate compounds contained in an airstream passing through the material. Disclosed materials can be utilized in forming protective garments, face masks, and the like.
