Methods of and systems for treating a web of chopped nonwoven mineral fibers passing through a chopped nonwoven mineral fiber mat process are provided. The methods comprise spraying strength aid onto the web of chopped nonwoven mineral fibers in a forming section of the chopped nonwoven mineral fiber mat process. The systems comprise a first spray bar comprising a delivery conduit configured to provide a flow of strength aid at a flow rate to one or more nozzles in fluid communication with the delivery conduit. The one or more nozzles are configured to receive the strength aid from the delivery conduit and to spray of the strength aid onto the web of chopped nonwoven mineral fibers in the forming section of the chopped nonwoven mineral fiber mat process.

A valve is disclosed that includes a valve body defining an inlet and a plurality of outlets, the inlet and the plurality of outlets cooperating to form a plurality of alternative fluid flow paths through the valve body. The valve further includes an outlet selection member carried by the valve body and defining a port configured to complete a fluid flow path selected from the plurality of alternative fluid flow paths. The valve further includes a first magnet assembly configured to enable reciprocation of the outlet selection member and a second magnet assembly configured to enable rotation of the outlet selection member. A washer fluid supply system incorporating the valve and a method of operating the valve are also disclosed.

Valve and associated system and method

A sampling nozzle is operatively coupled to a vacuum device and has a tubular coring member removably mounted at its upper end for extracting a sample of material from goods suspected of being hazardous. A canister is removably carried in the nozzle beneath the coring member in co-active, in-feed relation therewith for receiving the extracted sample. Air passages through the nozzle sidewall cooperate with a conical shroud carried on the upper end of the nozzle to create a blanket of air vacuum surrounding the coring member and the area around which the sample has been extracted. A high efficiency particulate filter may also be provided between the nozzle and the vacuum device. The sample is extracted while the surrounding blanket of air vacuum is active by placing the sampling nozzle against the goods to be sampled with the coring member in firm contact with the surface of the goods and pressing the nozzle causing the coring member to penetrate the material. The blanket of air vacuum surrounding the coring member draws airborne particulate material, vapors, and fumes in the vicinity of the extracted sample into the nozzle to be filtered. The cored sample falls through the coring member into the canister. The coring member is removed from the nozzle, and a compression spring ejects the container partially outward of the nozzle and it is capped under the same vacuum blanket to sealingly contain the extracted sample after which it may be safely transported to a convenient location for further analysis.
