An exemplary foam dispenser system includes a housing, a container, a motor, an air pump, a foam pump, a first mixing chamber, a second mixing chamber, a foam cartridge, and an outlet for dispensing foam. The container holds a foamable liquid. The foam pump has a liquid pump portion that pumps liquid, and an air pump portion that pumps air. The first mixing chamber is located downstream of the liquid pump portion and the air pump portion, and the liquid and the air mix in the first mixing chamber to create a first foam mixture. The second mixing chamber is located downstream of the first mixing chamber and the air pump, and the first mixture and air from the air pump mix in the second mixing chamber to create a second foam mixture. The second foam mixture travels through the foam cartridge and exits the outlet as rich foam.

Refill units for foam dispensers include a container for holding foamable liquid, a foam pump secured to the container, a foaming cartridge, an outlet and an actuation mechanism. The foam pump includes a housing, a liquid pump diaphragm, a plurality of air pump diaphragms, and a mixing chamber. An actuation mechanism releasably connects to a drive system in the dispenser. The actuation mechanism sequentially activates the liquid pump diaphragm and the air pump diaphragms when the refill unit is connected to the dispenser and the drive system. Sequential activation of the liquid pump diaphragm and air pump diaphragms causes the liquid pump diaphragm to pump at least a partial dose of liquid into the mixing chamber and the air pump diaphragms to pump at least a partial dose of air into the mixing chamber.

An exemplary foam dispenser includes a housing, a container for holding foamable liquid and a foam pump in fluid communication with the container. The foam pump has a plurality of diaphragm pumping chambers wherein at least one diaphragm pumping chamber pumps liquid, and at least two diaphragm pumping chambers pump air. The foam pump includes a liquid outlet valve having a cracking pressure of at least about 5 pounds per square inch; and two or more air outlet valves having cracking pressure of less than about 5 pounds per square inch. A mixing chamber is located downstream of the plurality of diaphragm pumping chambers for mixing liquid and air to form a foamy mixture. A foam cartridge located downstream of the mixing chamber and an outlet is provided for dispensing foam.

An aerosol-generating system is provided, including an aerosol-generating device in cooperation with an aerosol-generating article. The article includes a first sealed compartment having a tubular porous element and a delivery enhancing compound sorbed thereon; and a second compartment having a volatile liquid. The device includes an outer housing adapted to receive the article; an elongate piercing member for piercing the first and second compartments. The elongate piercing member includes a piercing portion adjacent a distal end of the elongate piercing member; a shaft portion; and an obstructing portion adjacent a proximal end of the elongate piercing member. The piercing portion has a maximum diameter greater than the diameter of the shaft portion, and the obstructing portion has an outer diameter such that it fits within the tubular porous element of the article when the article is received in the device. A corresponding aerosol-generating device and aerosol-generating article are also provided.

In accordance with one aspect of the disclosure, a lubricant application device for providing lubricant to an airfoil of a gas turbine engine is disclosed. The device may include a container for holding a lubricant, a fluid outlet in fluid communication with the container, a discharge mechanism controlling a flow of the lubricant from the container to the fluid outlet, and an extension tube in fluid communication with the fluid outlet. When the discharge mechanism is activated the lubricant may flow out of the container and through the extension tube. The extension tube may be dimensioned to fit between an airfoil root and rotor cavity of a gas turbine engine.

A sequentially activated multi-diaphragm foam pump for a foam dispenser includes a housing with a liquid pump portion and air pump portion secured. The liquid pump portion has a liquid inlet and valve, a liquid pump diaphragm, a liquid outlet and outlet valve. The air pump portion has a first and second air inlet and air inlet valve, a first and second air pump diaphragm, and a first and second air outlet. The foam pump also includes a mixing chamber that is in fluid communication with the liquid outlet, the first second air outlets. The liquid pump diaphragm, the first and second air pump diaphragms, operate in sequential order and the foamy mixture is dispensed through an outlet that is in fluid communication with the mixing chamber.

The aerosol-generating article include a plurality of elements coaxially aligned and assembled within a wrapper, the article having an outlet end and a distal end upstream from the outlet end. The article includes a liquid aerosol-forming substrate, and a liquid retention medium for retaining the liquid aerosol-forming substrate. The wrapper is formed from a sheet of liquid-impervious material, the liquid retention medium being in a first element of the plurality of elements.

The aerosol-generating system includes an aerosol-generating article with an aerosol-forming substrate, the aerosol-generating article having an outlet end and a distal end upstream from the outlet end. The system also includes an electrically operated aerosol-generating device including a housing having a cavity configured to receive the distal end of the aerosol-generating article, an electric heating element, and a heat diffuser including a non-combustible porous body for absorbing heat from the electric heating element such that, in use, air drawn through the aerosol-generating article from the distal end to the outlet end is heated by the heat absorbed in the porous body.

The aerosol-generating article is has an outlet end, a distal end upstream from the outlet end, and a mid-point located an equal distance between the outlet end and the distal end. The article includes a liquid aerosol-forming substrate contained within a frangible capsule, the frangible capsule being located between the distal end and the mid-point. At least a portion of a liquid retention medium is located between the distal end and the mid-point. The article is configured such that, during use, air is capable of being drawn through the article from the distal end to the outlet end.

The disclosure relates to a spray gun, and particularly relates to a suction pipe rotating device, and a spray gun with same. The device includes: a rotary knob rotatably arranged at a top of a gun body of the spray gun; a rotary connecting portion, where one end of the rotary connecting portion is arranged on the rotary knob and is movably inserted into a material suction hole of the spray gun; and an angle suction pipe including a straight pipe and an inclined pipe that are connected to each other, where the straight pipe is rotatably arranged in the material suction hole and is connected to the other end of the rotary connecting portion, the inclined pipe is obliquely arranged, and an end of the inclined pipe is close to a joint between a side wall and a bottom of a material barrel of the spray gun.
