A plural component spray gun system for use with a reactor having a chemical supply, a heater, a pump and a compressor, includes a trigger module with a spool valve having an air inlet and an activating outlet and an deactivating outlet; and an air body connected to the trigger module by an intermediate extending portion and having a mixing chamber to combine pressurized chemical components upon activation of a piston by pressure from the activating outlet.

A method and apparatus for applying a foamed mixture of paints on a structural surface. A continuous stream of high velocity gas moves through a nozzle and is directed toward the structural surface, and two or more paints may be intermittently moved into the gas stream of the nozzle and aerated and mixed with each other and moved with the gas stream to form a foam that is applied to the structural surface. The components of the foamed mixture may include single component or plural component materials such as polyurethane foam, adhesive, and polyurea formulations, and may be moved through a volumetric metering device consisting of material heaters, a heated hose, and an applicator gun. The nitrogen gas stream fluidizes the mixture as it passes through and out of the nozzle and forms the mixture into a foam that is applied to the structural surface.

Provided a spray tray device capable of rotatably spraying a die lubricant, wherein a rotating driving mechanism drive the rotating shafts and the spray tray rotators to rotate, and several external nozzles are arranged on the spray tray rotators. The air pipe joints and the lubricant pipe joints respectively input compressed air and a lubricant into cavities, formed between the spray tray rotators and the connection sleeve bodies, through the nozzle connection pipes, and then the compressed air and the lubricant are sprayed out through the external nozzles. The device implements that the same dosage of the lubricant is uniformly sprayed into the surfaces of the maximum pitch circles of upper and lower dies.

A spray gun includes a gun body and valves configured to control flow of material and air through the gun body. A trigger is mounted to the gun body and is disposed relative to the valves such that the trigger actuates the valves in sequence to begin air flow and material flow. A sensor senses when the trigger is in an actuated state and the sensor causes a pump to begin pumping material to the spray gun. Release of the trigger causes the trigger to leave the actuated state. A detent mechanism holes the trigger in a detent state intermediate the actuated state and a resting state. The sensor does not sense the trigger with the trigger in the detent state. The trigger maintains the valves open with the trigger in the detent state.

A forming method includes atomizing a raw material solution to form a raw material mist, mixing raw material mist and carrier gas to form a gas mixture, placing substrate on a stage, forming a film on the substrate by supplying gas mixture to substrate from a gas mixture supply means, and exhausting gas mixture after the film formation by exhaust means, in which a channel plate is arranged above substrate and faces the substrate via a space, a gas mixture flow is formed in the space above the substrate flowing linearly from the gas mixture supply means to the exhaust means such that the gas mixture flow flows along at least a part of a main surface of the substrate, and in the forming step and the exhausting step, at least a temperature T1 of the gas mixture supply means, and a temperature T2 of the channel plate are controlled.

A device for delivering a predetermined amount of a substance within at least one body cavity of a subject, where the predetermined amount is at an effective amount for treatment of obesity or binge eating disorder. The device includes (a) A volume to contain the predetermined amount of the substance. (b) A delivery end placeable in proximity to the body cavity. The delivery end is in fluid communication with the volume and comprises at least one orifice. (c) A valve mechanically connected to the volume, with at least two configurations: (i) an active configuration configured to deliver the predetermined amount of the substance; and, (ii) an inactive configuration, in which the valve prevents delivery of the predetermined amount of the substance. (d) A fluid tight chamber configured to contain a predetermined volume of pressurized gas at a predetermined pressure.

A spray gun for a plural component system is provided. The spray gun includes a first component delivery line and a second component delivery line. The spray gun also includes a nozzle, configured to receive and mix a first component received from the first component delivery line with a second component received from the second component delivery line. The spray gun also includes an air purge system configured to, when the spray gun is in a non-actuated position, purge the nozzle of the first and second components and, when the spray gun is in an actuated position, aid in atomization of the mixture of the first and second components.

The application provides a disinfecting device. The device comprises an aircraft trolley-sized body comprising two side surfaces. The body is adapted to move along a longitudinal axis of an aisle of an aircraft such that the side surfaces face two opposing sides of the aisle. The device includes a powering unit, at least one air compressor for providing compressed air, a disinfectant bottle for storing liquid disinfectants, and at least two nozzle assemblies. Each nozzle assembly includes an electrically actuated valve, a connector, and at least three nozzles. The compressed air flows from the compressor to the valve, to the connector, and to the nozzles to form droplets of disinfectants. The nozzles are provided on upper surfaces of the body such that the nozzles point away from the respective side surfaces for spraying the disinfectants onto objects located on the two opposing sides of the aisle.

An apparatus for printing discrete high-resolution high-density features on a surface is provided using an aerosol stream. An aerosol chamber has a transport gas that enters through a port and entrains aerosol in an aerosol chamber to form an aerosol-laden transport gas. A flow cell is provided that has a flow cell channel and sheath gas conduits. The aerosol-laden transport gas passes through the flow cell channel and is surrounded by sheath gas passed through the sheath gas conduits. At least one aerodynamic lens receives the aerosol-laden transport gas surrounded by sheath gas. A method of printing the aerosol droplets from the aerosol-laden transport gas onto the substrate with a mean diameter of 0.5 to 8 microns is also provided.

A method of preventing damage generated in a microbial aerosolization process is provided. The method includes a first step of injecting microorganisms into an atomizer containing a phosphate-buffered saline (PBS) solution in which one or more selected from the group consisting of ascorbic acid (AA) and bovine serum albumin (BSA) are contained; and a second step of injecting compressed air into an atomizer and spraying a bioaerosol.
