A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a twist-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.

A system having a material sensor system coupled to a material tank is provided. The material tank is configured to receive a quantity of the material and output a flow of the material. The material sensor system includes a float system coupled to an inner surface of the material tank. The float system includes a float configured float within a float cavity. The material sensor system includes a switch coupled to an outer surface of the material tank. The switch is communicatively coupled to the float system through a wall of the material tank, and the switch is configured to send one or more signals to a control system when the float engages the switch.

A nozzle monitoring system is provided for a sprayer system of a work vehicle. The system includes a first sensor configured to generate signals associated with vibrations of a first nozzle apparatus on the work vehicle that disperses a primary fluid from the sprayer system during operation; and a controller having a processor receiving the signals generated by the first sensor and having a memory coupled to the processor and storing instructions. The processor executes the stored instructions to: convert the vibrations into a frequency domain representation; generate an image from the frequency domain representation; classify the image to generate a clog condition probability; and generate, based on the clog condition probability, a command to initiate a cleaning event of the first nozzle apparatus.

A nozzle apparatus includes a manifold defining a nozzle cavity within an interior, a fluid inlet passage, a fluid outlet passage, an air outlet passage, and an air inlet passage. A nozzle holder and a nozzle element are selectively pivotable within the nozzle cavity. In the nominal position, the nozzle element inlet is oriented toward the fluid passage inlet and the nozzle element outlet is oriented toward the fluid passage outlet such that the primary fluid flows through the fluid inlet passage and out of the nozzle outlet through the fluid outlet passage. In the cleaning position, the nozzle element inlet is oriented toward the air outlet passage and the nozzle element outlet is oriented toward the air inlet passage such that the flow of air is directed through the air inlet passage, and out of the air outlet passage to direct debris out through the air outlet passage.

A liquid delivery system including a spray nozzle that includes a spray tip. The spray nozzle receives liquid via a liquid supply line. The spray tip of the spray nozzle generates an atomized liquid spray output when the liquid flowing through the spray nozzle passes through the spray tip. The spray nozzle includes a fluid control valve and a flow meter. The fluid control valve controls a flow rate of the liquid dispensed by the spray nozzle. The flow meter determines a flow rate of the liquid dispensed by the spray nozzle. The spray nozzle also includes a housing configured to retain and support the fluid control valve and the flow meter. The liquid delivery system includes a controller that provides feedback and control of the spray nozzle by receiving a flow rate signal from the flow meter and outputting a control signal to the fluid control valve.

A hand-held sealing device may be used for sealing a tubeless tire on a corresponding wheel rim. The wheel rim may have a valve stem hole to receive a valve stem. The hand-held sealing device may include a device body. The device body may include an air output nozzle, a directed air outlet defined in the air output nozzle, and an air inlet defined in the device body. The air inlet may be fluidly communicated with the directed air outlet. The hand-held sealing device may also include a valve assembly disposed between the directed air outlet and the air inlet. A cable may be slidably disposed in the air output nozzle. The cable may pass through the directed air outlet. A valve stem engagement member may be configured to removably attach to the valve stem. The valve stem engagement member may be connected to the cable.

A dispenser system for a canister. The system includes an actuator with universal and replaceable component parts. The actuator may include an actuator frame, plunger, control, stem connector and canister connector. The actuator may be within a housing form factor that holds additional sensors. The sensors may be removable components that are used as part of a larger canister system. The sensor may communicate with a mobile device to indicate when to stop dispensing contents from the canister. The sensor may additionally be designed to prevent inadvertent actuation until the sensor is removed.

A sprayer system for spraying water, onto and for absorption by, a surrounding area, such as used in wastewater treatment. The sprayer system includes a substantially vertical tubular housing extending from a well base to a distal end from which water communicated to the sprayer system is discharged. The tubular housing includes an inner tubular casing slidably supporting a piston assembly which is movable from the well base to the distal end in response to water communicated from a source to the well base. The piston assembly includes a primary check valve that is biased into engagement with an associated seat and includes a spray nozzle located downstream of the main check valve. When water from the source is applied to an effective pressure area on the piston assembly, an upwardly directed force is applied to the piston assembly when water is delivered to the well base. At least one bypass passage communicates bypass water to a region defined between the piston housing and an inside wall of the tubular casing so that warming water is delivered from the well base and flows around the outside surface of the piston assembly, whereby icing, which would otherwise block movement of the piston assembly, is inhibited.

A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.

This installation for application of a coating product comprises a print head equipped with a plurality of nozzles each controlled by a valve supplied by a product source. A product accumulator, installed on a product circulation circuit, comprises a deformable or movable wall delimiting, at least in part, a first chamber of variable volume supplied with coating product and a second variable-volume chamber supplied with gas, under a predetermined pressure equal to a nominal operating pressure of the print head. The first chamber of variable volume is supplied or purged with coating product due to a difference between an instantaneous coating product ejection rate from the print head and a supply rate to the print head from the source. A control unit adjusts an operation setpoint value of the source as a function of the difference between instantaneous ejection flow rate and supply flow rate, to reduce this difference.
