A dual slot die coater including a lower plate, an intermediate plate positioned on the lower plate and an upper plate positioned on the intermediate plate, a lower slot being formed between the lower plate and the intermediate plate, and an upper slot being formed between the intermediate plate and the upper plate. The lower plate, the intermediate plate and the upper plate have a lower die lip, an intermediate die lip and an upper die lip, each forming an front end with respect to the current collector, respectively, and a distance between the current collector and the lower die lip is larger than a distance between the current collector and the upper die lip and a distance between the current collector and the intermediate die lip.

A method for applying contrasting thermoplastic markings to a roadway in a single pass. The contrast road marking apparatus includes two or more ribbon guns configured to apply a first thermoplastic marking to a roadway surface area and a second thermoplastic marking, which comprises a color that contrasts with a color of the first thermoplastic marking, to another roadway surface area. The resulting contrast road marking has no visible or substantially negligible overlap or gap between the individual thermoplastic markings.

A coating die includes: a first body; a second body; a discharge port; an intermediate member; a first shim to define a first flow passage; a second shim to define a second flow passage; and a confluence passage in which the first flow passage and the second flow passage join together and that communicates with the discharge port. The first shim includes a pair of first arms, and the second shim includes a pair of second arms. Each first arm includes a first female portion and a first male portion. Each second arm includes a second female portion and a second male portion. The first female portion and the second male portion are engaged with each other, and the first male portion and the second female portion are engaged with each other.

A coating composition for application to a substrate utilizing a high transfer efficiency applicator. The coating composition includes a carrier and a binder. The coating composition has an Ohnesorge number (Oh) of from about 0.01 to about 12.6, the coating composition has a Reynolds number (Re) of from about 0.02 to about 6,200, and the coating composition has a Deborah number (De) of from greater than 0 to about 1730.

A production line for powder coating items, such as food pieces, having a conveyor and a powder depositor arranged having a powder reservoir, a screen, a vibratory actuator to apply intermittent vibrations to the screen to cause powder to pass through apertures in the screen; and a controller to control the interval between the intermittent vibrations so that powder is deposited predominantly onto the items as they pass below the screen.

A dual-slot die coater including a first slot and a second slot for discharging a coating solution in a direction opposite to gravity, a first die block vertically installed on a rear portion of an upper surface of a base, a second die block arranged on a front surface of the first die block to form the first slot between the second die block and the first die block, and a third die block arranged on a front surface of the second die block to form the second slot between the third die block and the second die block, and further includes an alignment block provided between a front portion of the upper surface of the base and a lower surface of the second die block and fastened and coupled to the lower surface of the second die block and a lower surface of the first die block by bolts.

A casing of an aircraft turbomachine includes an annular shell extending around an axis A and made of a composite material having fibers that which are woven and embedded in a resin. An annular layer made of abradable material extends inside the shell, around axis A and is obtained by spreading and polymerizing a paste. Support panels extend around axis A and are interposed between the shell and the abradable layer.
