Abstract: A cover assembly for mounting onto a rescue vehicle includes a housing extending between a first end and a second end. The housing includes a first wall, a side wall, and a top wall defining an interior region. A hose reel extends within the interior region of the housing and is coupled with the first end of the housing and the second end of the housing. The hose reel is spring loaded within the housing. A cover is disposed about the hose reel, and the cover includes a bottom end having at least one fastening mechanism configured to engage with the rescue vehicle. The cover is actuated between a stored configuration and a deployed configuration.

Abstract: Methods of monitoring a chemical dosing subsystem for treating a fluid in a waste collection system are disclosed. The methods include deploying at least one sensor to the waste collection system, transmitting to an external controller data for a measured parameter of the fluid or treating agent, and comparing a treatment regimen determined responsive to the data to a reference protocol to determine whether the chemical dosing subsystem requires adjustment. Methods of treating a fluid in a waste collection system having a chemical dosing subsystem are also disclosed. Waste treatment management systems including a chemical dosing subsystem, a sensing subsystem, and an external controller are also disclosed. Methods of retrofitting a waste treatment management system are also disclosed.

Abstract: A biofilter irrigation system comprises a cylindrical vessel having a central axis, a media bed positioned within the vessel, a spray head system positioned above the media bed, the spray head system comprising a central hub positioned at the central axis of the vessel, at least one arm extending distally from the central hub toward a wall of the vessel and configured to rotate about the central axis, and a plurality of nozzles connected to the at least one arm. The biofilter irrigation system further comprises a fluid outlet positioned below the media bed.

Abstract: A rolled sheet dispensing cabinet for storing and dispensing rolled sheets includes a housing having a top, a bottom, a front, a back, and opposing sides defining an internal space. Each of a plurality of rods is coupled to and extends between the opposing sides. Each of a plurality of slots is positioned in the front and extends from proximate to each opposing side. The slots are parallel to the top and the bottom. Each slot is positioned proximate to a respective rod. The rods are positioned in the internal space and are configured for insertion into tubular cores of rolled sheets. The slots are positioned in the front and are configured for insertion of leading edges of the rolled sheets. The leading edges protrude from the front of the housing and are configured for grasping by a hand of a user to extract a portion of the rolled sheet.

Abstract: The invention can provide or facilitate systems and methods for feeding a slurry and, in particular, to systems and methods for treating wastewater streams with a slurry having periodic flushing of conduits.

Abstract: A prepreg which is capable of being cured-in-place into a solid surface by irradiation, heating or a combination of the two is prepared. The cured-in-place solid surfaces can be used as veneer cladding for rigid substrates such as floor and wall tiles, kitchen and bath counter tops, sinks, cabinet door veneers, bath surrounds, architectural surfaces such as columns and roofs and the like.

Abstract: The present disclosure relates generally to reinforced composite resin formulations used for molding body panels for transportation vehicles. Particularly, but not by way of limitation, the disclosure relates to low-density thermosetting composite molding compounds used to mold body panels and having a density of less than 1.6 grams/cubic centimeter and excellent surface smoothness without the use of hollow glass microspheres.

Abstract: An association complex formed in a liquid environment from a metal-based chromium (VI) reducer and a non-lignosulfonate-based complexing agent is introduced into cement clinker or hydratable cement particles. In preferred embodiments, the formation of the association complex provides storage stability to the chromium reducer within the cement, such that the level of chromium (VI) after water is added to the cement remains less than 2 ppm for certain duration after mixing with water and without the necessity for further additions of chromium reducer during said duration (e.g., 26-84 or more days after addition). Compositions having the association complex are also described.

Abstract: The present invention is directed to ion-conducting, nitrile containing sulfonated polymeric materials formed by the direct polymerization of sulfonated monomers and aromatic nitrile monomers. These nitrile containing sulfonated polymers may be used to form membranes that have application in fuel cell and ion exchange technologies. In particular, the membranes may be used in hydrogen, direct methanol, reformate, and other direct oxidation fuel cells.

Abstract: The present disclosure relates generally to resin formulations for sheet molding compounds. Particularly, but not by way of limitation, the invention relates to low-density thermosetting sheet molding compounds (SMC) comprising an organic-modified, inorganic clay, a thermosetting resin, a low profile agent, a reinforcing agent, a low-density filler, and substantially the absence of calcium carbonate. The present disclosure relates particularly to the use of alternative reactive monomers present as aromatic, multiethylenically-unsaturated compounds that aid thermosetting SMC in yielding exterior and structural thermoset articles, e.g. auto parts, panels, etc that have Class A Surface Quality.
