  • Patent number: 10731768
    Abstract: A fluid dispenser system is disclosed that can have a plurality of dispensers, each having a valve. Each valve can be connectable in series with another valve. The dispenser system can include a manifold permitting passage of a common fluid therethrough. Any of the valves connected to two adjacent valves can be removable without removing either of the valves to which it is connected. The common fluid can have a fluid pressure associated therewith. The fluid pressure can generate a tension force for pushing two adjacent valves apart and thereby lock the valves into a series connection. A method of removing a valve from a series of valves comprises stopping flow of the common fluid through the manifold, thereby releasing the tension force. The valve intended to be removed can be rotated, and thus removed with respect to the valve intended to be left in the series connection.

  • Patent number: 10731087
    Abstract: The present invention generally relates to a method for separating solids from liquid in a slurry comprising solids and a liquid (e.g., an aqueous solution). More specifically, the method comprises contacting an effective amount of a high molecular weight polymeric flocculant with the slurry in a tanker truck or as the slurry is flowing to the truck, allowing the solids to settle during a settling time whereby the solids settle to the bottom of the tanker truck, and the liquid is removed from the tanker truck at a level above the settled solids. The high molecular weight polymeric flocculant can comprise repeat units derived from a cationic monomer, an anionic monomer, a nonionic monomer, or a combination thereof.

  • Publication number: 20200239928
    Abstract: A method for detecting the presence of bacterial spores is described by measuring microbial metabolic activity over time. Spores are distinguished from vegetative cells and other microorganisms by detecting a burst of metabolic activity indicating germination of spores. This method may be used to detect bacterial spores in a commercial process system, such as a papermaking system within the time frame of a typical work shift.
