A roll to roll fabrication apparatus includes an injection plate for injecting a chemical treatment liquid on a film transferred from a supplying roll to a collecting roll; and liquid blocking rolls disposed between the supplying roll and the collecting roll, and configured to prevent the chemical treatment liquid injected from the injection plate from being introduced to another process region.

A method of treating a tubular surface which defines an axis extending from a first surface end to a second surface end includes partially surrounding the tubular surface, at a first position, with a first set of treating units, with the treating units arranged in a first arcuate array. Furthermore, each treating unit is configured to include a plurality of first applicator heads. Additionally, an embodiment of the method includes determining a position of each of the plurality of first applicator heads relative to the tubular surface and moving the first set of treating units from the first position towards a second position. In one non-limiting example, the method further includes independently controlling each of the plurality of first applicator heads to selectively apply a first treatment as the first set of treating units moves from the first position towards the second position.

A system paints the external and internal faces of a splayed end of a hollow shaft, with a rotary paint bench. This splayed end includes an end support face and an opposite support face. The system includes a fixing ring applied against the end support face and a counter-ring applied against the opposite support face as well as a fixing device, an end hub fixed to the fixing ring in line with the splayed end, and including a running belt suitable for resting on two rollers of the bench, a hollow external hub including two half-hubs delimiting a running belt suitable for resting on two rollers of the bench, and fixed to the counter-ring while surrounding the splayed end.

Methods and systems comprising a first and a second powder coating apparatus, with each apparatus comprising a tubular barrel having an axial bore extending longitudinally therethrough, are usable for coating an interior surface of a tubular member. Each coating apparatus comprises a conical member connected with the tubular barrel and at least one gas conduit connected to the tubular barrel for communicating gas into the tubular barrel. The at least one gas conduit contains a gas flow control valve connected thereto for controlling the volumetric flow rate of gas through the at least one gas conduit. Each coating apparatus further comprises at least one container for holding a coating material, an inlet conduit for communicating the coating material into the axial bore of the tubular barrel, and a plurality of gas nozzles connected to the tubular barrel for inducing spiraling gas flow through the axial bore of the tubular barrel.

A nozzle for use in an etching apparatus and an etching apparatus including the nozzle are provided. The nozzle includes: a hollowed main body having a connector at one end thereof and a main-body outlet at the other end thereof, a main-body connection part being provided at an outer wall of the main body, said one end of the main body being connected with a pipe via the connector and a nozzle sleeve including a nozzle-sleeve connection part and a nozzle-sleeve outlet, the nozzle sleeve being connected to an outer side of said the other end of the main body having the main-body outlet through the nozzle-sleeve connection part and the main-body connection part and the nozzle sleeve is movable relative to the main body in an outflow direction of the main body.

The present invention relates to a colmating improvement device for cork stoppers, comprising at least three cylindrical shaped rotating means, able to receive a cork stopper entering in a rotational movement with a slight pressure, which stopper is inserted through an insertion tubular device assisted by two pneumatic cylinders. The device further comprises two openings, an inlet opening and an outlet opening, two electric motors/reduction gears, a worm, a chain and a tank that can contain a substance consisting of a binder and cork dust with a solid content between 50 and 100%.

A prosthetic heart valve includes a base and a plurality of polymeric leaflets. Each leaflet has a root portion coupled to the base, and each leaflet has an edge portion substantially opposite the root portion and movable relative to the root portion to coapt with a respective edge portion of at least one of the other leaflets of the plurality of leaflets. Each leaflet includes) at least two polymers along at least one portion of the leaflet, and each leaflet has a composition gradient of each of the at least two polymers along at least one portion of the leaflet.

A coating apparatus for coating a perimeter surface of a pipeline. A frame selectively mounts a sprayer on the pipeline. The sprayer can spray fluid along a flow path in a spraying mode and preparation mode. In the preparation mode, a fluid diverter moves into the flow path to divert the fluid delivered from the sprayer away from the pipeline. In the spraying mode, the fluid diverter moves out of the flow path to permit the sprayer to coat the perimeter surface of the pipeline with a curable liquid. A vacuum system can draw a vacuum through the diverter to remove the fluid the sprayer sprays in the preparation mode. The flow path can be located in a spray shroud. The diverter can fluidly couple the vacuum system to the shroud interior in the spraying mode to remove overspray.
