Provided herein is a system for disinfection and deactivation of contaminants, and more particularly to a self-contained compressed air disinfection system and method to deactivate pathogens on all surfaces and/or in the air of the targeted interior space comprising reusable compressed air cylinders and single-or multi dose containers of disinfectant or decontaminant.

A medical device including an application device with a first fluid path and a container movably attached to the application device. The container and the application device have a second fluid path therethrough, the container includes an inner chamber that is intermediate proximal and distal portions of the second fluid path, the inner chamber is fluidly isolated from the proximal portion of the second fluid path at a first position of the container, and the inner chamber is fluidly coupled to the proximal and distal portions of the second fluid path at a second position of the container. The first fluid path bypasses the container and the passage of fluid through the first fluid path is separately controllable from the passage of fluid through the second fluid path.

A portable water batching system for mixing fireproofing coatings. A controller allows the user to pre-set the volume of a batch of water to be dispensed into the mixer for the fireproofing coating. The water batching system can also be used in conjunction with an acid/activator injection system that allows an acid solution to be introduced to the fireproofing coating slurry prior to reaching the spray gun used for application. The water batching system and acid injection system can be used in tandem with a system that proportionally controls the amount of acid solution pumped from the acid injection system to the amount of fluid pumped from the water batching system. The systems can each be equipped with data sensors to allow for recording of information for each batch of fireproofing coating.

The present invention provides unique pressure actuated valves and related methods that may be used in applications where a plurality of fluid emission devices are provided on a plurality of lines containing fluid under pressure, in order to prevent fluid from escaping from the fluid emission devices until a consistent threshold or predetermined level of fluid pressure is obtained in the lines, without causing significant water pressure and/or flow loss through the valves. Valves of the present invention include a housing having an upper body and a lower body that may be coupled together to form an inner chamber, the lower body having an inlet in communication with a source of fluid under pressure, the upper body having an outlet in communication with a fluid emission device. A hollow movable fluid transmission piston is provided in the chamber for communicating between the inlet and outlet. The chamber formed between the upper and lower bodies may be provided with cup seals at opposite ends of the chamber to reduce friction and prevent fluid from entering therein, and a side air vent. A wider lower end of the piston is urged toward the lower housing body using a biasing mechanism, which pushes an O-ring at the lower end against a stop to prevent fluid from entering into the hollow center of the piston. When fluid with a sufficient pressure is provided from the source, it pushes the O-ring away from the stop and against the urging of the biasing member, allowing fluid to flow around the stop, through the center of the piston, and out through the upper body into the fluid emission device. The vent in the chamber allows air inside the chamber (surrounding the biasing mechanism) to escape so that there is no added air pressure within the chamber to be overcome by the fluid pressure.

A programmable, electronically controlled sprinkler system has a hermetically sealed internal chamber which encloses all of the internal water flow, valves, mechanical and rotational components and a plurality of magnetic coupling arrangements which allow external motors to control operation of the internal mechanical components without requiring any hydraulic seals.

The disclosure relates to a pressure cleaning device comprising a pressure generating unit for pressurizing a fluid and for dispensing a pressurized fluid via a hose attachment, preferably via a hand gun or via a cleaning nozzle. The pressure cleaning device can be operated in at least two different operating modes. According to the disclosure, a preferably electric pressure sensor for determining an actual operating pressure and/or a flow rate sensor for determining an actual flow rate and a control device are associated with the pressure generating unit. The control device is designed to control the pressure generating unit in particular, based on a respectively set operating mode in accordance with an actual operating pressure and/or an actual determined flow rate.

A product system for an agricultural sprayer includes a product tank configured to store an agricultural product. A reclaim system can be configured to provide the agricultural product within a flow assembly to a product tank. A computing system can be communicatively coupled to the reclaim system. The computing system can be configured to receive information indicative of one or more characteristics of the agricultural product inputted into the fill station during a fill mode; detect termination of the fill mode; and activate a reclaim mode to move the agricultural product from the flow assembly to the product tank through activation of the reclaim system, wherein one or more operating conditions of the reclaim mode are based on the one or more characteristics of the agricultural product.
