The subject matter of this specification can be embodied in, among other things, a fuel delivery component, a substantially rigid, unitary structure formed as a single piece of material, and at least a first seamless lumen defined by the unitary structure as a first loop.

The present disclosure includes a mobile liquid dispensing system adaptable to be implemented on an arm-bed truck. The disclosure includes an apparatus comprising a spray rig capable of engaging arms of an arm-bed truck, and a carrier operable to be hoisted by an arm-bed truck. A method of mobile liquid dispersion is also presented that be performed from an arm-bed truck. The disclosure offers many advantages in the art, including novel uses of an arm-bed truck and a spray rig that is resistant to damage from impacts.

An apparatus for cooling a steel sheet includes: an apparatus body provided spaced apart from a steel sheet in the conveying path of the steel sheet; and a cooling unit provided in the apparatus body to supply a cooling fluid. The apparatus body includes: a first edge body that faces a first edge portion extending a certain distance from one side end of the steel sheet toward the center of the steel sheet; and a second edge body that faces a second edge portion extending a certain distance from the other side end of the steel sheet toward the center of the steel sheet. The first and second edge bodies may have stepped cross-sections in a direction perpendicular to the conveying direction of the steel sheet.

The disclosure concerns a device for dispensing an atomized spray of a cosmetic composition. The device is capable of individual or commercial use, and provides yaw and pitch actuation of an operational head, along with the atomized spray to deliver the cosmetic composition to the body of a user. Electronics are configured to acquire data from a disposable spray bottle assembly, and approximate remaining volume or spray time according to the data. A linear laser provides guidance to the user for standing in order to receive optimal spray coverage.

A grinding apparatus includes an ultrasonic cleaning unit. The ultrasonic cleaning unit includes a pair of side walls that surround the inside and the outside of a base and grindstones, a bottom surface that connects the pair of side walls, a jet port that is formed in at least either of the side walls or the bottom surface and that jets a cleaning liquid toward at least either of the base or the grindstones, a cleaning liquid supply section that supplies the cleaning liquid to the jet port; an ultrasonic vibrator that applies an ultrasonic wave to the cleaning liquid supplied from the cleaning liquid supply section, and an electric power supply section that applies electric power to the ultrasonic vibrator.

A vehicle door epidemic prevention device applied to a public transportation vehicle is disposed on the public transportation vehicle, especially a bus. The public transportation vehicle has at least one door. The door has a doorway for passengers to enter and exit. The doorway is provided with at least one door panel. The door panel is provided with at least one disinfection unit. The disinfection unit faces the doorway when the door panel is in an open position. The disinfection unit is connected with a control unit for activating the disinfection unit to disinfect the passengers passing through the doorway when the door panel is in the open position, so as to achieve the purpose of epidemic prevention.

A self-cleaning, automated apparatus with a filter for fluids includes a nozzle unit assembly that has two nozzle tubes, one inside of another. Each of the tubes has a respective pattern of one or more slots or holes. As the tubes rotate, one with respect to the other, part of the pattern of the one coincides at times with part of the pattern of the other, resulting in a jet of fluid directed toward a filter to remove debris from the filter. The filter is rotated so the jet can reach all parts to be cleaned. The respective patterns of the two nozzle tubes may be an approximation of a helix and/or an approximation of a line.

Described herein is a sidewall suitable for use in a metallurgical furnace, and metallurgical furnace having the same. The sidewall has an upper wall, an outer wall coupled to an outer side of the upper wall, and extending downward from the outer wall. A sloped wall is coupled to an inner side of the upper wall. The sloped wall extends downward and inward from the upper wall. The sloped wall has a first surface facing the outer wall and a second surface facing a centerline of the sidewall. A spray cooling assembly is disposed between the sloped wall and the outer wall. The spray cooling assembly is configured to spray coolant on the first surface of the sloped wall.

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.

A misting system includes at least one support pipe, at least one first water supply conduit, a first plurality of anti-drip misting nozzles and at least one first valve. In some embodiments, the misting system also includes a base including least one second water supply conduit, a second plurality of anti-drip misting nozzles, and at least one second valve. The first plurality of anti-drip misting nozzles provide general misting to an area and to (generally) an upper body of a user located about the area. The second plurality of anti-drip misting nozzles provide misting to (generally) a lower body of the user. Used together, the first plurality of anti-drip misting nozzles and the second plurality of anti-drip misting nozzles provide misting to the area, as well as full body misting to the user.
