A mold paint-spraying device includes a frame and a mold fixed to the frame. A motor is fixed to the frame, an output end of the motor is fixedly connected to a mounting rack, a servo motor and a linear guide rail are fixedly connected to the mounting rack, a rail slide is arranged on the linear guide rail, a screw nut is fixed on the rail slide, a spray gun is fixed on the screw nut, and an output end of the servo motor is connected with a screw matching the screw nut.

A system for coating a heat transfer tube for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube, and is able to uniformly coat a plurality of heat transfer tubes. In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.

A water display is described whereby parabolic water streams may be controlled so as to appear to move towards or away from each other or step over each other.

An adaptable method and apparatus for applying pressurized liquids to the exterior of industrial surfaces, such as large, commercial buildings. The method and apparatus are capable of being programmed for automated use and capable of being used with fewer people, reducing the need for more expensive equipment and allowing companies to maintain and reach areas that they may not have been able to easily access before. The pressurized liquid application could be for the application of paint or high-pressure water solutions for cleaning.

Embodiments relate to surface treating a substrate, spraying precursor onto the substrate using supercritical carrier fluid, and post-treating the substrate sprayed with the precursor to form a layer with nanometer thickness of material on the substrate. A spraying assembly for spraying the precursor includes one or more spraying modules and one or more radical injectors at one or more sides of the spraying module. A differential spread mechanism is provided between the spraying module and the radical injectors to inject spread gas that isolates the sprayed precursor and radicals generated by the radical injectors. As relative movement between the substrate and the spraying assembly is made, portions of the substrate is exposed to first radicals, sprayed with precursors either one of the spraying modules or both spraying modules using supercritical carrier fluid, and then exposed to second radicals again.

A three-dimensional (3D) printing system and method for printing with the 3D system. The 3D system includes a pneumatic dispense gun for mixing a thermoset resin and catalyst and dispensing a catalyzed resin to a rotary dispense valve for application of the catalyzed resin to a substrate on a movable table. The dispense gun contains a catalyst injection unit and a mixer for mixing the catalyst with the thermoset resin. The mixer is downstream of the catalyst injection unit and the catalyst injection unit includes a catalyst injector and a distribution ring surrounding the catalyst injector. One or more first pumps are provided for pumping the thermoset resin from a storage container to the pneumatic dispense gun. A second pump is provided for pumping the catalyst from a storage container to the dispense gun.

The systems and methods described herein relate to basting food-related items. The food-related items may include baked goods, baking sheets, cake pans, cupcake pans, and the like. The food items may include pastries, baked good, pies, etc. The item to be basted, glazed, or otherwise deposited with a fluid is placed in a target area. A movable head is then able to move along a track and distribute a fluid over the fluid- related item. The item is stationary during the process.

An apparatus for treating a surface of a structure includes a main carriage having an accessory carriage that is vertically movable with respect to the main carriage.

A powder coating plant for coating a workpiece with coating powder includes a booth, which receives the workpiece delivered via a floor conveyor. In addition, the powder coating plant has an upper spray applicator arrangement for spraying coating powder downward, and a lower spray applicator arrangement for spraying coating powder upward. The upper and the lower spray applicator arrangement are thereby oriented toward the same workpiece. In addition, a manipulator is provided, to which the upper and the lower spray applicator arrangement is fastened. The manipulator is formed such that the spray applicator arrangements can be moved at least in the transport direction of the workpiece by the manipulator.

The arrangement of a combustor and a device for selective non-catalytic reduction includes a nozzle for injecting a reagent, a control system for controlling the flow from the nozzle, the control system being arranged for generating a pulsed flow from the nozzle.
