Disclosed herein are embodiments of a plasma treatment system and methods for utilizing directed plasma to reduce instances of gas venting and leaking of contents from plastic bottles due to scratches occurring on sealing interfaces of the bottles and closures. In an embodiment, a plasma treatment system for repairing scratches applied to PET bottles comprises one or more plasma nozzles disposed along a bottle filling line and a plasma being issued by the plasma nozzles to repair the scratches. The plasma nozzles are arranged into a configuration that uniformly distributes plasma to all parts of a neck finish comprising the PET bottles. The plasma treatment of the PET bottles is performed prior to capping of the bottles. In an embodiment, the plasma treatment is performed after filling the bottles with contents so as to avoid a risk of scratches from misaligned filling tubes.

In some embodiments, for example, a system includes a controller configured to provide one or more control signals; a heater coupled to the controller, where the heater comprises one or more heating elements arranged to heat a blasting medium in response to the one or more control signals; a chamber coupled to the controller, where the chamber comprises an agitatable drum shaped to receive a plurality of additively manufactured objects, and to agitate the plurality of additively manufactured objects in response to the one or more control signals; and an applicator coupled to the controller, where the applicator comprises a nozzle operative to direct, in response to the one or more control signals, a plurality of thermally conductive particles in the blasting medium toward the plurality of additively manufactured objects within the agitatable drum.

An object of the present invention is to provide a method of joining resin tubes, in which the degree of freedom of selecting a tube material is large, and further a defect such as stiffness and contraction at joining portions of the tubes is not developed. The method of joining resin tubes according to the present invention is a method of joining resin tubes so that a first tube is joined to a second tube, the first tube and the second tube each being made of synthetic resin, the method comprising: a surface activation step of activating each of a joining region of the first tube and a joining region of the second tube; and an adhesion step of adhering the joining region of the first tube obtained via the surface activation step with the joining region of the second tube obtained via the surface activation step to each other.

The tube is stretchable. The tube is stretched by applying tension in a longitudinal direction. The tube returns to its short state by releasing the above-described tension applied in the longitudinal direction. A plurality of protrusions are formed on an inner surface of the tube. Each of the plurality of protrusions extends in a circumferential direction. The plurality of protrusions are arranged side by side in the longitudinal direction of the tube. A pitch of the protrusions is less than or equal to 1.5 m.

For producing a dome-shaped element (2) provided with thermal protection for a solid propellant rocket engine, a coupling annular body (4) is arranged in a mold (5) and has a surface (20) that is clean and activated, by an atmospheric-pressure plasma treatment, before depositing a primer layer (26) and an adhesive layer (27) on the surface (20); ablative material is then automatically applied to the adhesive layer and to an area (17) of the mold (5) so as to form a series of superimposed layers (30).

A system is provided for generating plasma within narrow diameter tubes, e.g., tubes with an inner diameter of less than 1 millimeter. The system may comprise the tube, a nozzle connected to at least one end of the tube configured to supply a gas into the interior of the tube at atmospheric pressure, at least one ring-shaped anode electrode and configured to surround an outer surface of the tube, at least one ring-shaped cathode electrode spaced apart from the anode electrode along the longitudinal axis and configured to surround the outer surface of the tube, and a voltage source connected to the at least one anode electrode. When activated, the system is configured to generate an electric field between the electrodes which ignites a plasma within the gas in the interior of the tube.
