    Abstract: An improved protective covering for paint brushes, paint rollers, and other paint applicators, consisting of a sheath of flexible, impermeable material. In one embodiment, a protector for a paint brush, roller or other paint applicator comprising a sheath of impermeable flexible material. Said sheath is comprised of two membranes. The inner membrane is polyethylene vinyl acetate, or ethylene vinyl acetate. This provides intrinsic adhesiveness thereby improving performance. The surface of said membrane has a frosted or translucent appearance. This membrane adheres to the paint on the tools for an improved barrier between the paint and oxygen. When the wet surface of the tool makes contact with the frosted membrane, the wet or paint shows through more clearly, while the dry areas maintain a frosted appearance, thereby indicating the product is working. The outer membrane is polyethylene plastic.

    Abstract: An atmospheric pressure plasma source includes a body including a distal end, a blade extending from the distal end and terminating at a blade edge, a plasma-generating unit, and a plasma outlet communicating with the plasma-generating unit and positioned at the distal end. The plasma outlet is oriented at a downward angle generally toward the blade edge, wherein the plasma outlet provides a plasma path directed generally toward the blade edge. The plasma may be applied to the coating at an interface between the coating and an underlying substrate. While applying the plasma, the blade is moved into contact with the coating at the interface, wherein the blade assists in separating the coating from the substrate while one or more components of the coating react with energetic species of the plasma.

  • Patent number: 8940103
    Abstract: Provided is a method for a resist removal system comprising a processing chamber and treatment liquid delivery system for single substrate processing. A primary stripping chemical is flowed in the treatment liquid delivery system at a primary temperature and flow rate; a secondary stripping chemical is injected at a first mixing point at a secondary temperature and flow rate. A tertiary stripping chemical is injected at a second mixing point at a tertiary temperature and a tertiary flow rate. The treatment liquid is dispensed onto a portion of the surface of the substrate wherein one or more of the primary temperature, secondary temperature, tertiary temperature, the primary flow rate, the secondary flow rate, and the tertiary flow rate are adjusted to meet a target strip rate and selectivity of strip over etch of silicon nitride and silicon oxide.

  • Patent number: 8876978
    Abstract: An object is to reduce changes in mechanical properties of a gas turbine blade base material during repair or regeneration of a gas turbine blade. For this purpose, a gas turbine blade after being operated is washed by being immersed into a strong alkaline washing solution, and the gas turbine blade after being washed with the strong alkaline washing solution is washed with water. The gas turbine blade after being washed with water is then washed by being immersed into a weak acid washing solution, and the gas turbine blade after being washed with the weak acid washing solution is subjected to heat treatment. The gas turbine blade after the heat treatment is then immersed into a strong acid washing solution, whereby the coating formed on the surface of the gas turbine blade is removed.

  • Patent number: 8871028
    Abstract: Process and system for removing printing in metallic packages used in drinks, food and other applications in general, comprising the removal of ink before the cure thereof, by means of spray with ink remover liquid and non abrasive friction. Preferably, said liquid is an alkaline aqueous solution, which is sprayed onto the package surface simultaneously with the friction thereof with a soft and non abrasive element. In a preferred embodiment, said friction results in the rotation of the package around the longitudinal axis thereof, which is mounted on a rotative support, and the soft non abrasive element in contact with the surface thereof keeps motionless.

  • Patent number: 8728245
    Abstract: The present invention includes a process using environmentally friendly materials for the removal of adhesive residues from hard substrates, particularly vehicles, e.g., cars, trucks, buses, aerospace vehicles including airplanes, and the like. The process uses a novel adhesive remover composition comprising one or more non-halogenated organic solvents, a non-abrasive thickening agent, a surfactant, and a vapor-pressure modulating agent. The total Hansen Solubility Parameter (?t) at 25° C. for each of the non-halogenated organic solvents is from about 14 MPa1/2 to about 24 MPa1/2. The invention provides a cost effective, safe, environmentally friendly adhesive remover composition specifically formulated for removal of, e.g., pressure sensitive adhesive residues from large areas of aircraft composite and aluminum surfaces, as well as others.
