An axial flow filter element having alternating flat and pleated layers of fluid permeable filter media which form channels with an open cross section, one end of a first group of channels and the other end of a second group of channels being tightly sealed such that fluid being filtered must pass through one of the filter layers to pass through the filter element, a peripheral seal for sealing the inflow side of the filter from the outflow side in a housing, and a support body arranged in the f...

The present invention provides a fluid discharge apparatus for producing a curtain of air. The apparatus comprises a body member having an air inlet chamber and an air outlet chamber. The air outlet chamber is in fluid communication with the air inlet chamber. The body member defines a discharge orifice through which fluid is discharged from the body member with the discharge orifice being in fluid communication with the air outlet chamber. The air outlet chamber has a pair of opposing sidewalls...

An air-bag is formed from two super-imposed layers of fabric which define between them at least one inflatable region. A gas supply duct extends into the air-bag. Apertures are formed in the gas supply duct. The gas supply duct is of elongate form, and is formed from a fabric having intersecting warp and weft yarns, the warp and weft yarns being inclined at an angle of between 30.degree. and 60.degree. and preferably 45.degree. to the axis of the gas supply duct.

In an air purifier including a streamer discharge part (40) generating plasma by streamer discharge, a catalytic part (34) promoting the treatment of air using active species contained in the plasma and a dust collecting part (33) collecting dust in the air, the streamer discharge part (40), the dust collecting part (33) and the catalytic part (34) are arranged in sequence from the upstream side of the air flow to allow the entire face of the catalytic part (34) to effectively work and also perm...

A register to be mounted in a vent opening of a wall, floor, or ceiling for regulating the passage of air. The register includes a grill having a plate with grill openings for directing the passage of air therethrough, a frame connected to the bottom of the grill, at least one damper for regulating air flow through the register, a pivotal connection connecting the damper to the frame to allow pivotal movement therebetween, and a control mechanism for moving the damper between an open position pe...

An object is to provide an air conditioner in which a desiccant air conditioner is combined with a refrigerating device to cool an indoor by a refrigeration cycle including a compressor and the like and in which a drop of energy efficiency is suppressed. An air conditioner 200 includes a desiccant air conditioner 220 and a refrigerating device 210 which cools the indoor by a usual refrigeration cycle, this refrigerating device 210 has an auxiliary heat exchanger 17 between an outlet side of a he...

An air-bag comprising an inflatable element having an inflatable region and a gas inlet throat extending from the inflatable region, a gusset of excess fabric being present in the region proximate to the junction between the gas inlet throat and the inflatable region.

An air bed is disclosed. The air bed includes an air pump, an inflatable body and a cabinet detachably or fixedly connected to the inflatable body. The cabinet is a rollable and foldable airbag having at least one valve for inflation and deflation and includes at least one recess for receiving an air pump and other articles.

A domestic air purifier includes a plurality of non-linear conduits through which room air is drawn and into which fluid is introduced to remove particulate matter from the air. A plurality of non-linear conduits having a plurality of fluid spraying nozzles provides thorough mixing between air and fluid to maximize the removal of particulates from the air. The fluid circulates continuously from a reservoir through the nozzles and conduits back to the reservoir. Simple fluids, such as water, are ...
