The present invention is directed to an applicator having an agricultural product mechanical and/or pneumatic conveying system which transfers particulate material from one or more source containers to application equipment on demand, and meters the material at the application equipment. The conveying system includes a static distributor interconnecting the supply lines of the conveying system with the distribution lines connected to the individual nozzles. The static distributor includes internal structures that effectively divert the incoming particulate material evenly across the interior of the static distributor such that the particulate material is evenly distributed into each of the distribution lines. The static distributor accomplishes this without the need for any moving parts or control systems/devices. In addition, damage done to the particulate material flowing through the distributor is not high, and the operation of the distributor creates a lower pressure drop across the distributor than prior art vertical distributors.

The present invention relates to articles comprising a plurality of molded hollow parts having different central axis through the hollow elements further having passages in walls of the hollow parts transverse to the central axis of the hollow parts. The present invention also relates to methods of applying two part curable materials to substrates using the molded parts of the invention as mixing elements.

The heat exchanger (1) contains a jacket element (2) and an insert element (3), wherein the insert element (3) is arranged in the operating state in the interior of the jacket element (2). The insert element has a longitudinal axis (4). The insert element (3) contains an insert jacket element (31) and a plurality of web elements (9, 10), the web elements (9, 10) having a first end (13) and a second end (14). The first end (13) and the second end (14) of each web element (9, 10) are connected to the insert jacket element (31) at different locations. At least a portion of the web elements (9, 10) includes web element channels (11, 12), the web element channels (11, 12) extending from the first end (13) of the web element (11) to the second end (14) of the web element (11). An intermediate jacket element (5) is arranged between the insert jacket element (31) and the jacket element (2).

Methods related generally to the removal of atmospheric pollutants from the gas phase, are provided. The methods involve contacting a first stream comprising NO and/or NO.sub.2 with a second stream comprising (ClO.sub.2).sup.0 to provide a third stream comprising NO and NO.sub.2 at a molar ratio of about 1:1; and contacting the third stream with a fourth stream comprising an aqueous metal hydroxide (MOH) solution to convert NO and NO.sub.2 to MNO.sub.2.

A mixer/heat exchanger insert or mixer/heat exchanger having a geometry which leads to less fouling of a fluid to be temperature-controlled.

Methods related generally to the removal of atmospheric pollutants from the gas phase, are provided, as well as related apparatus, processes and uses thereof. A single-stage air scrubbing apparatus is provided that includes at least one reaction vessel, at least one introduction duct, and a turbulence component, wherein a residence time is sufficient to allow the conversion of at least one atmospheric pollution compound to at least one other compound, molecule or atom. In some embodiments, the at least one atmospheric pollution compound comprises nitrogen oxide, sulfur oxide or a combination thereof. Additionally, methods of removing atmospheric pollution compounds from a waste gas stream are disclosed that include introducing a waste gas stream and at least one additional gas stream, mist stream, liquid stream or combination thereof into a single-stage air scrubbing apparatus at a flow rate sufficient to allow for conversion of the at least one atmospheric pollution compound.

One aspect of the invention relates to a method comprising a single stage conversion of an atmospheric pollutant, such as NO, NO.sub.2 and/or SO.sub.x in a first stream to one or more mineral acids and/or salts thereof by reacting with nonionic gas phase chlorine dioxide (ClO.sub.2.sup.0), wherein the reaction is carried out in the gas phase. Another aspect of the invention relates to a method comprising first adjusting the atmospheric pollutant concentrations in a first stream to a molar ratio of about 1:1, and then reacting with an aqueous metal hydroxide solution (MOH). Another aspect of the invention relates to an apparatus that can be used to carry out the methods disclosed herein. The methods disclosed herein are unexpectedly efficient and cost effective, and can be applied to a stream comprising high concentration and large volume of atmospheric pollutants.

A pipe welding structure includes: a channel plate that includes a fluid channel; through-hole plates stacked on the channel plate, each of the through-hole plates having through holes that communicate with each other and forming a combined through hole; and a pipe inserted into the combined through hole and welded to one of the through-hole plates disposed farthest from the channel plate, the pipe internally including a pipe channel that connects to the fluid channel.
