The metering system includes a metering pump to convey a discharge of the multi-component composite material through the outlet opening. The metering system includes a control unit to output, to the metering pump, a control signal comprising control information andvadjust a metering output of the multi-component composite material through the outlet opening of the mixing head based on the control signal.

A robot end effector for dispensing an extrudable substance comprises a chassis and cartridge bays, attached to the chassis and each shaped to receive a corresponding one of two-part cartridges. Robot end effector also comprises a dispensing valve, attached to the chassis and comprising a valve inlet and a valve outlet. The valve outlet is in selective fluidic communication with the valve inlet. Robot end effector further comprises a manifold, comprising a manifold outlet and manifold inlets, which are in fluidic communication with the manifold outlet. Robot end effector additionally comprises a plunger assembly, comprising pairs of plungers and arranged to concurrently extrude contents of the two-part cartridges through the cartridge outlets. Robot end effector also comprises an electric motor, attached to the chassis and configured to selectively move the plunger assembly relative to the chassis.

A system for field internally coating a pipe joint comprising a polymer application unit, which has a first cart configured to selectively advance inside a pipe; a first and a second tank configured to contain a first and a second polymer component respectively; a mixer to mix the first and the second component; a first and a second pump to feed the first and the second component respectively from the first and the second tank to the mixer; an applicator to apply the polymer to the pipe; and a conduit comprising a free end configured to be placed near the applicator to feed the polymer from the mixer to the applicator.

An apparatus for coating carpet webs in a coating apparatus with varying adhesives includes a controller, one or more sensors for detecting a volume of a puddle of the adhesive pooled in front of an application roller, and an electronic valve in fluid communication with each of a plurality of mixers. The electronic valve directs flow of the adhesive from any of the mixers to the coating apparatus. To switch from one of the adhesives to new adhesive as a next carpet web passes through the coating apparatus, the controller calculates a remaining length of the carpet web that can be coated with the adhesive in the puddle of adhesive based on the volume of the puddle, so that the puddle of the adhesive coats the carpet web, and then proximate a seam to the next carpet web, the new adhesive begins to coat the next carpet web.

In one embodiment, a substrate treatment apparatus includes a mixer configured to mix a first liquid including a metal element and a second liquid being basicity to generate a third liquid including the metal element and being basicity. The apparatus further includes a supplier configured to supply the third liquid to a substrate. The apparatus further includes a first flow path configured to convey the third liquid from the mixer to the supplier not through a filter that removes particles from the third liquid.

A robot end effector (100) for dispensing an extrudable substance (102) comprises a chassis (110), a static mixer (101), and cartridge bays (122), extending from the chassis (110). Each of the cartridge bays (122) is shaped to receive a corresponding one of the two-part cartridges (104). Fluidic communication between the selected one of the two-part cartridges (104) and the static mixer (101) is established when the cartridge bays (122) are moved to a predetermined position with respect to the chassis (110).
