Abstract: A filter assembly includes a filter pad comprising fibers including natural, synthetic and/or hybrid fibers. A stabilizer frame formed of a non-metallic material may be imbedded in the filter pad. The stabilizer frame may be configured to provide support to the filter pad to maintain the filter pad in a generally flat configuration. In accordance with a particular embodiment, the filter pad may be comprised of at least first and second fibrous mats that are coupled together. In this embodiment, the stabilizer frame may be disposed between and coupled with the first and second fibrous mats.

Abstract: An odor absorption component is fitted to a duct in a manner that does not obstruct fluid flow through the duct while simultaneously facilitating absorption of odors from a fluid flowing within the duct. The absorbing component comprises one or more carrier structures that support a fabric/textile treated with an odor absorption coating. In one position, the carrier structures can be placed on the wall of the duct such that a plane of the support structure is parallel to and in physical contact with the fluid flow within the duct. The carrier structures may also be placed in another position within the duct such that at least two surfaces of the carrier structure that extend in a longitudinal direction along its length are parallel to and in the path of the fluid flow within the duct.

Abstract: A large single crystal of a complex such as an organic carboxylic acid metal complex, which crystal is useful as an adsorbent of various gases and vapors of organic solvents and as a hydrogen-absorbing material, as well as a process for producing the crystal, is disclosed. Two layers wherein an upper layer thereof is constituted by a solution containing a metal salt and an organic carboxylic acid having a conjugated system, or a solution containing a metal salt of the organic carboxylic acid having a conjugated system, and wherein a lower layer of the two layers is constituted by a solvent which is not miscible with the solvent of the solution, is formed. Vapor of pyrazine or a substituted pyrazine from a solution of pyrazine or the substituted pyrazine is introduced into the upper layer to allow reaction, thereby forming a large single crystal(s) of the organic carboxylic acid metal complex at the interface between the two layers, which crystal(s) has(have) a longer side with a size of not less than 0.8 mm.

Abstract: A bow-reduced precipitator collector plate assembly and an appertaining method include a precipitator collector plate that contacts a spring-like stiffening element configured to be attached to a fixed anchor or an adjacent anchoring collector plate. The stiffening element is configured to apply a force in a direction normal to a primary plane, which is generally co-linear but opposite in direction of a direction of bowing, of the precipitator collecting plate.

Abstract: An electrostatic precipitator includes an upright hollow body having a lower smoke inlet and an upper smoke outlet, with a pair of spaced horizontal partitions formed in the hollow body between the inlet and outlet. A set of parallel ducts extends vertically between the partitions, and a pair of distributor frames is arranged in the hollow body, with one of the distributor frames disposed over the ducts and the other of the distributor frames disposed under the ducts. Between the distributor frames is stretched a plurality of wires that extend through respective ducts. Furthermore, each of the distributor frames is formed with a plurality of terminals to be electrically connected to one electrode of a DC high-voltage power supply, but the ducts are adapted to be electrically connected to the other electrode of the DC high-voltage power supply.

Abstract: An electronic dust collector has a discharge line spaced parallel to a dust collector electrode. Discharge line fixing parts at the ends of the discharge line are bent outward to increase the distance from the dust collector electrode, thereby reducing the likelihood of abnormal discharge between the discharge line fixing parts and the dust collector electrode. In another embodiment, the discharge line and the discharge line fixing parts remain in alignment, and the ends of the dust collector electrode facing the line fixing parts are bent outward. The electronic dust collector may be part of an air conditioner. The dust collector electrode has a heater therein for self cleaning.

Abstract: An electrical dust collector has an ionization section for ionizing dust in air, and a collection section for collecting the ionized dust. The ionization section includes a high voltage wire to which a high voltage is applied, and a grounding member disposed near the high voltage wire so as to be spaced by a predetermined distance. An insulating member is disposed between the high voltage wire and the grounding member. The insulating member electrically insulates the space between the grounding member and at least an end of the high voltage line. An electrical discharge between the high voltage wire and the grounding member is prevented by the insulating member, whereby the operation of the electrical dust collector is stabilized.

Abstract: Discharge electrode wires are arranged between parallel discharge tubes by attaching one end of the discharge electrode wire to an end clip within the frame of an electrostatic precipitator having rows of collecting electrode plates. The opposite end of the discharge electrode wire is detachably connected with an in-line spring at one end of the spring. The opposite end of the in-line spring is detachably connected with another end clip. The end clips are detachably engagable with the tubes of the frame and the discharge electrode wire is arranged between parallel tubes by attaching one end clip to one tube and extending the discharge electrode wire through use of the in-line spring in order to attach the second end clip to a parallel frame tube. This arrangement allows for easy access and removal of a damaged discharge electrode wire.
