A vehicular cleaning system performs cleaning to remove foreign matter attached to a cleaning target in a vehicle. The vehicular cleaning system includes: an air pump driven to generate an air spray; a washer pump driven to supply a washing solution; a spray nozzle which blows an air-liquid mixed fluid, obtained by mixing the air spray and the washing solution, onto the cleaning target; a washing solution storage unit configured to store the washing solution supplied from the washer pump, and to be capable of discharging the stored washing solution when the washing solution is to be mixed with the air spray; and a mixing and outputting unit configured to blow the air-liquid mixed fluid, obtained by mixing the air spray and the washing solution introduced from the washing solution storage unit, from the spray nozzle toward the cleaning target.

A method for applying an ultraviolet curable coating material and a method for producing an ultraviolet cured film include the steps of: supplying an ultraviolet curable coating material containing an ultraviolet curable acrylic monomer into a mixer under a condition of greater than or equal to 8 MPa without diluting the ultraviolet curable coating material with an organic solvent; supplying carbon dioxide with a critical pressure or more into the mixer; mixing the ultraviolet curable coating material and the carbon dioxide supplied into the mixer to form a mixed fluid; spraying the mixed fluid under a condition of a critical pressure or more of the carbon dioxide to form a coating film; and irradiating the coating film with ultraviolet rays to form an ultraviolet cured film.

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 metering and application system for a moisture-curing polymer material includes a reservoir for the polymer material and a first pump and a second pump, wherein the polymer material is conveyable by the first pump from the reservoir to the second pump. In addition, a gas metering device with a defined pressure ratio is provided to bring a gas to a defined pressure, wherein the gas metering device is connected to the input of the second pump on its outlet side. In addition, a mixer for mixing the polymer material and the gas and a valve arranged downstream of the mixer for metering and a nozzle for applying the polymer material/gas mixture are provided.

A method for applying an ultraviolet curable coating material and a method for producing an ultraviolet cured film include the steps of: supplying an ultraviolet curable coating material containing an ultraviolet curable acrylic monomer into a mixer under a condition of greater than or equal to 8 MPa without diluting the ultraviolet curable coating material with an organic solvent; supplying carbon dioxide with a critical pressure or more into the mixer; mixing the ultraviolet curable coating material and the carbon dioxide supplied into the mixer to form a mixed fluid; spraying the mixed fluid under a condition of a critical pressure or more of the carbon dioxide to form a coating film; and irradiating the coating film with ultraviolet rays to form an ultraviolet cured film.

A foam discharging nozzle of the invention is a foam discharging nozzle for a foam discharging device, including: a foam diffusion space to which foam produced by mixing a liquid and a gas is supplied from a foam supply opening located on an upper side; and at least one foam discharging opening formed in a bottom portion of the foam diffusion space. The area of the bottom portion of the foam diffusion space is wider than the area of the foam supply opening. The centroid of the foam discharging opening does not match the centroid of a supply opening projected portion formed by projecting the foam supply opening onto the bottom portion parallel to a central axis of the foam diffusion space.

A gas mixing apparatus includes: a discharge port of gas provided near conduit space through which the high-viscosity material can flow; a piston pump including a cylinder that can communicate with the conduit space through the discharge port, a piston arranged inside the cylinder, and a drive device for moving the piston between a top dead center and a bottom dead center inside the cylinder; a discharge valve that opens and closes the discharge port; and a suction valve that opens and closes a suction port of the gas into a cylinder space, in which the cylinder forms the cylinder space having a predetermined volume when the piston is located at the top dead center, and in which a tip of the piston approaches the discharge port when the piston is moved toward the bottom dead center.

A coating apparatus that can coat a substrate while assuring a volatile organic compound (VOC) free atmosphere outside the equipment. The coating apparatus can be used in-line, where flat materials and substrates that are typically carried along a conveyer may enter the coating apparatus without requiring the substrate to be moved into any other configuration. The coating apparatus may be configured to permit the user to perform any number of treatment steps while providing isolation between the steps. The coating apparatus can be formed by nesting one or more inner chambers inside a central chamber which may be nested inside an outer chamber. The outer chamber may be, for example, a vacuum chamber to ensure removal of VOCs.

An insulation material formed of a composition, and a method of making an insulation material is provided. The composition forming the insulation material includes magnesium oxide; at least one of magnesium chloride, magnesium sulfate, and hydrates thereof; water; a foaming agent; a thickener; and a foam stabilizer. The composition is foamed to promote aeration of the composition to reduce density of the insulation material formed from the composition.

A distribution system for delivering preheated epoxy material for spray application includes a bundle of lines that terminate on their far end in a manifold. The distribution system is uniquely constructed in a manner such that it delivers the correct materials individually to the manifold while maintaining separate flows of the materials. This separation of the materials until ready for spraying prevents mixing of the two-part epoxy which at the elevated delivery temperatures would result in early curing of the epoxy within the delivery system itself. The bundle of lines contains at least one and preferably two base epoxy delivery lines, at least one catalyst delivery line, at least one heating circuit and an auxiliary heater at the manifold end. The manifold terminates in a static mixer that in turn delivers the mixed epoxy to a spray head for spray application to the substrate.
