Abstract: A mixing system mixes liquid adhesive and gas to create a solution. The mixing system it a manifold defining an adhesive input that receives the liquid adhesive, a gas input that receives the gas, a mixing chamber in fluid communication with the adhesive and gas inputs, an output that outputs the solution, and an output passage extending from the mixing chamber to the output. The mixing system also includes a rotor that rotates within the mixing chamber about a longitudinal axis so as to mix the solution, a motor that rotates the rotor, and a static mixer positioned within the output passage that statically mixes the solution flowing through the output passage.

Abstract: A syringe for dispensing liquid materials to a substrate. In one embodiment, the syringe includes a barrel having a first end, a second end, and an interior reservoir. A piston is slidably disposed within the reservoir and is movable to increase or decrease a volume of the interior reservoir near the first end of the barrel. A first end of the piston has a hemispherically-shaped surface profile, with an elongated apex extending therefrom, to dispense liquid from the first end of the barrel when the piston is moved in a direction toward the first end.

Abstract: A handheld valve dispenser includes a barrel having proximal and distal ends and a fluid chamber adapted to store a fluid. A dispense tip is coupled to the distal end of the barrel and includes a piercing element and a valve seat. The piercing element is configured to pierce the seal and establish an aperture therethrough when the dispense tip is first coupled to the barrel. A valve stem is received within the fluid chamber and is movable between a closed position in which the valve stem sealingly contacts the valve seat to prevent fluid dispense, and an open position for dispensing fluid. The barrel may include an outer barrel member and a disposable inner barrel liner removably received within the outer barrel member.

Abstract: A dispensing assembly including a cartridge and a retainer. The cartridge includes a dispensing end and defines a reservoir for holding a liquid. The dispensing end includes a connector portion for receiving an end fitting with a rotational connection. The retainer includes a first open end and receives the cartridge such that the connector portion communicates with the first open end in a manner allowing connection of the end fitting. The retainer couples with the cartridge in a manner preventing relative rotation between the cartridge and the retainer.

Abstract: A liquid dispensing valve includes a valve body, a valve seat, and a reciprocating valve member engageable with the valve seat for controlling flow through a liquid outlet. A calibration device includes a rotatable stroke control stop member and a rotatable reference ring. The reference ring and stop member may be initially rotated to a zero position and, subsequently, the stop member may be rotated to set the desired stroke length. One or more fluid fittings are provided and sealed against the valve body using a clamp plate.

Abstract: A curable liquid dispensing pen has a pen body to which a curable liquid dispensing reservoir may be removably attached. The pen body further has a coupling which may be coupled to a source of pressurized air. The air is directed through a passage in the pen body to the reservoir. The pressurized air moves a piston in the reservoir to cause curable liquid to be dispensed from the reservoir. A controller provides a timed pulse of pressurized air to the curable liquid dispensing pen and this controls the volume of curable liquid dispensed from the reservoir.
