A fluid dispensing gun for 1K-polyurethane foam includes a dispensing tube with a dosing nozzle at its outlet, a spring-loaded needle co-axially moveable in the dispensing tube for opening and closing the dosing nozzle, a trigger actuating the needle to open the nozzle and to dispense the fluid, a regulator regulating the degree of opening of the nozzle outlet and a coupler coupling a pressurized can to the gun. It also concerns a method for dispensing 1K-polyurethane foam. The fluid dispensing gun includes a delivery device delivering a curing fluid essentially parallel to the nozzle outlet that includes a curing fluid reservoir, a curing fluid outlet situated near the nozzle and a curing fluid line connecting the curing fluid reservoir and the curing fluid outlet, the trigger activating the delivery device. The curing fluid delivered in the same direction as the 1K-polyurethane foam and separately therefrom makes the foam cure more rapidly.

The invention comprises an apparatus and/or a method of use thereof for dispensing whipped cream, comprising: a profi including a pressure containment housing, a first receiving port integrated into the pressure containment housing, a dispensing port integrated into the pressure containment housing, and at least a first pressure cartridge containing at least a liquid form of nitrous oxide, where the pressure cartridge includes a pressure gas delivery port and where a connection between the receiving port and the pressure gas delivery port form: (1) a section of a pressure containment unit encompassing contents of the pressure containment housing and the pressure cartridge and (2) an open path between the pressure containment housing and the pressure cartridge.

A backpack material dispenser that includes a pumpless pressure tank for storing and discharging a material under pressure contained in the pressure tank and a hose and a shut off valve connected to an output opening of the pressure tank for allowing flow of the material from the pressure tank under pressure and through a nozzle communicating with a discharge end of the hose. A discharge valve communicates with the nozzle proximate the hose for allowing controlled discharge of the material from the nozzle. A backpack assembly mounts the pressure tank for being carried by a user. A charging tank contains a gas under pressure to charge the pressure tank to a predetermined pressure, and a releasable connector of the charging tank attaches to a complementary connector of the pressure tank for charging the pressure tank with the gas under pressure to the suitable pressure tank pressure.

Applicant discloses a novel method of spray applying multiple courses of a rapid cure, two part polymer sealant to an aircraft surface. The method sometimes uses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The multiple courses cure to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.

A device configured to deliver a pressurized fluid includes a body having an input opening for receiving the pressurized fluid and an output opening for delivering the pressurized fluid, a handle defining a lumen, wherein the lumen is configured to receive a container containing the pressurized fluid, and at least one aperture fluidly connecting the lumen to an atmosphere external of the device.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

An aerial paint spraying vehicle includes a body and a paint reservoir removably coupled to the body and configured to store paint. The aerial paint spraying vehicle includes a pressure vessel removably coupled to the body and configured to pressurize the paint from the paint reservoir. The aerial paint spraying vehicle includes a paint applicator assembly configured to receive the pressurized paint and expel the pressurized paint through a spray nozzle towards a target surface.
