A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.

Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes an embedded moisture barrier and/or vapor barrier, and the topical coating comprises an oil barrier comprising acrylate, rice bran wax, pectin, and pea protein.

There is disclosed a valve assembly for washing cameras or sensors of an autonomous vehicle. The valve assembly includes a single fluid injector having a fluid inlet, a fluid outlet, and a fluid passage in fluid communication with the fluid inlet and the fluid outlet. A cup is disposed over an upstream portion of the fluid injector, relative to a direction of fluid flow through the fluid injector. A lower housing is disposed over and surrounds a downstream portion of the fluid injector, relative to the direction of fluid flow therethrough. A bracket member extends from the lower housing. The bracket member is configured for connecting to an anchor member for attachment within the autonomous vehicle. In this way, the valve assembly may be easily secured within a vehicle for providing a desired amount of fluid to the lens of the vehicle camera or sensor.

An additive delivery device includes a water supply waterway; and a delivery unit to deliver additives to the water supply waterway; an outlet of the water supply waterway being connected to a nozzle structure. A washing machine includes an inner drum configured to hold a load and the additive delivery device. An inlet of the water supply waterway communicates with a water inlet pipe, and the nozzle structure of the additive delivery device jets an additive solution towards the inside of the inner drum of the washing machine. Additives in the washing machine directly flow to the nozzle structure by the water supply waterway and are directly jetted into the inner drum by the nozzle structure without passing through a water box and an outer drum outside the inner drum, and then, onto the load in the inner drum to increase the utilization ratio of the additives.

Systems and methods for containing fluid splash include using a fluid flow spaced from a vessel and/or fluid surface to effectively trap materials from a fluid stream flowing through the fluid flow. The fluid flow creates a spray envelope in connection with the fluid surface and/or vessel and substantially prevents droplets of the fluid stream from exiting the vessel. The fluid flow is created by allowing a supply fluid to flow through a nozzle oriented to cast a spray pattern into the vessel and/or into contact with the fluid surface. The fluid flow may be selectively activated and deactivated and/or be automatically (e.g., light or motion) activated and deactivated.
