An aeroponics system includes a spray manifold with a fluid inlet, a plurality of fluid injectors attached to the spray manifold and in fluid communication therewith, and a fluid pump in communication with the fluid inlet of the spray manifold. A timing controller is in electronic communication with the plurality of fluid injectors. A power source is in electronic communication with the fluid pump, the plurality of fluid injectors, and the timing controller. The fluid pump is configured to maintain a constant high pressure within the spray manifold. The timing controller is configured to control the timing and pattern of energization of the plurality of fluid injectors. When any one of the plurality of fluid injectors is energized, fluid is allowed to pass from the spray manifold through that fluid injector.

A nozzle include a first portion, a second portion joined to the first portion, and a third portion joined to the second portion. The first portion includes a first inner wall surface and a first flow channel including a first inlet and a first outlet. The second portion includes a second inner wall surface and a second flow channel including a second inlet having an inner diameter less than an inner diameter of the first outlet and a second outlet. The third portion includes a third inner wall surface and a third flow channel including a third inlet having an inner diameter greater than the inner diameter of the second outlet and a third outlet. The third flow channel includes a diameter-decreasing section having an inner diameter that gradually decreases and a straight section having an inner diameter less than the inner diameter of the second outlet and constant.

An effective implementation is shown for a height adjustment system for a plurality of spray guns used in a line striper.

A liquid spraying system having a liquid spray section and a controller for controlling liquid to the spray section. The controller includes a valve operable between multiple positions for controlling the supply of liquid to the spray section and enabling the flow of liquid from the spray section to a flow back line only after the liquid supply to the spray section has been terminated.

A process for the production of spunbonded nonwoven (1) is shown, wherein a spinning mass (2) is extruded through a plurality of nozzle holes (4) of at least one spinneret (3, 40, 50) to form filaments (5) and the filaments (5) are drawn, in each case, in the extrusion direction, wherein the filaments (5) are deposited on a perforated conveying device (10) to form a spunbonded nonwoven (1) and wherein the nozzle holes (4) of the spinneret (3, 40, 50) are arranged along a main axis (6) oriented in a transverse direction (12) to the conveying direction (11) of the conveying device (10) so that the spunbonded nonwoven (1) formed on the conveying device (10) extends in this transverse direction (12). So as to enable the spinning width and the basis weight distribution of the spunbonded nonwoven to be adjusted reliably and, respectively, to allow the basis weight distribution to be kept constant during operation by means of the process, it is suggested that the spinning mass throughput (31) of the nozzle holes (4) is adjusted variably along the transverse direction (12).

An applicator and method of use is disclosed for applying coatings and paints to various surfaces. As shown, the sprayer may have an undercarriage frame that supports three-wheels. All three wheels may run parallel with the first wheels and second wheels attached to the sprayer frame via an undercarriage with the third wheel positioned behind and between both the first and second wheels on a separate arm or frame. The width of the sprayer booms may be adjusted. The undercarriage may be folded entirely or only a portion therein. The arm of the third wheel may be folded or telescope, as required by a particular application. A handle, which may be adjustable, may be positioned between the sprayer frame and the undercarriage. Use of the applicator according to the method discussed herein reduces operator fall exposure and increases application efficiency.

The present invention relates to a novel sprinkler device. The device is designed to prevent the spread of wildfires to residential areas. The device comprises a plurality of sprinkler nozzle heads secured to a pole component. Each sprinkler nozzle head comprises a built-in sensor that will detect the presence of a fire, automatically activating the sprinkler nozzle head to extinguish a fire. Further, each sprinkler nozzle head comprises a backup system in case of a power failure, or the sensor fails. Further, the sprinkler heads can comprise a solar-powered battery and a manual power switch.

An apparatus includes an exterior surface including an aperture, a sensor defining a field of view oriented through the aperture, a nozzle shell on the exterior surface and including a nozzle panel facing the aperture, and a heating element disposed in or on the nozzle panel. The nozzle panel includes a nozzle.

A bead flow sensor module includes a housing, a beam, and a sensor. The beam extends into a flow channel of the housing through which a flow of beads and compressed air flows. The sensor outputs a signal indicative of bead impacts on the beam. A system incorporating the bead flow sensor module includes a compressed air source, a bead hopper, and a bead dispenser. The compressed air source delivers a flow of compressed air to the bead hopper. A flow of beads carried by the compressed air discharges from the bead hopper along a flow pathway connecting the bead hopper to the bead dispenser. The bead flow sensor module positioned along the flow pathway outputs the signal from which a bead flow volume through the bead dispenser is determined.

Various disclosed embodiments include illustrative sprayer assemblies, electric motor assemblies, and vehicles with cooling assemblies for stator windings of electric motors. An illustrative sprayer assembly includes a first spray device assembly configured to receive a fluid and further configured to spray the fluid therefrom. A second spray device assembly is configured to receive the fluid and is further configured to spray the fluid therefrom. A connecting tube is fluidly couplable to the first spray device assembly and the second spray device assembly and is configured to provide the fluid from the first spray device assembly to the second spray device assembly.
