Abstract:
Coating compositions, methods and articles of manufacture comprising a nanoparticle system employing same to impart surface modifying benefits for all types of soft surfaces, and in some cases, hard surfaces, are disclosed. In some embodiments, dispersement of nanoparticles in a suitable carrier medium allows for the creation of coating compositions, methods and articles of manufacture that create multi-use benefits to the modified surfaces. These surface modifications can produce long lasting or semi-permanent multi-use benefits that, in some embodiments, may include at least one of the following improved surface properties: cleaning, wettability, liquid strike-through, comfort, stain resistance, soil removal, malodor control, modification of surface friction, reduced damage to abrasion and color enhancement, relative to the surfaces unmodified with such nanoparticle systems.
Abstract:
A device and a method for facilitating the deposition and patterning of organic materials onto substrates utilizing the vapor transport mechanisms of organic vapor phase deposition is provided. The device includes one or more nozzles, and an apparatus integrally connected to the one or more nozzles, wherein the apparatus includes one or more source cells, a carrier gas inlet, a carrier gas outlet, and a first valve capable of controlling the flow of a carrier gas through the one or more source cells. The method includes moving a substrate relative to an apparatus, and controlling the composition of the organic material and/or the rate of the organic material ejected by the one or more nozzles while moving the substrate relative to the apparatus, such that a patterned organic layer is deposited over the substrate.
Abstract:
The automated system includes a fluid dispenser having an applicator tip which is used to apply a fluid to an object. A compliance mechanism is utilized to assist in maintaining the applicator tip of the fluid dispenser in contact with the object during the coating operation. A robot can be utilized to advance the object past the applicator tip during the coating operation. The fluid dispenser is mounted on a movable arm to allow the fluid dispenser to be moved or rotated into and away from the position where fluid is applied to the object. The automated system provides a fluid application system that can apply a precise and repeatable layer of fluid to an object. The use of the robot allows larger objects to be easily handled and for the coating process to be done in a rapid fashion. The automated system is flexible and can readily accommodate changes in the object that is to be coated or the configuration of the coating that is to be applied to the object.
Abstract:
Spray on polyurethaneurea coatings provide corrosion resistance over long periods of time to marine fixtures, particularly of active metals such as aluminum and steel. Radar arches, fishing platforms, railing systems, etc. can maintain their aesthetics over extended periods of time, even in salt water environments, when the coating has been penetrated to the metal surface.
Abstract:
Systems and methods are provided whereby pumpable viscous fibrous material may be applied onto surfaces of high temperature process vessels while hot (i.e., while at or near such vessels' high operational temperatures of several hundreds up to several thousands of degrees Fahrenheit). More specifically, there are preferably provided a lance having a nozzle structure at a distal end thereof, and a pump system for pumping a pumpable fibrous refractory material to the nozzle. The lance has a length sufficient to allow it to be inserted into the high temperature process vessel so that the nozzle structure is adjacent an area in need of repair while an operator holds a proximal end thereof outside the vessel. In use, the lance is inserted into the process vessel while the process vessel is at or near its high operational temperature so that the nozzle structure is positioned adjacent to an area of the process vessel wall in need of repair, and so that the lance may be manipulated from outside the process vessel during repair of the wall thereof. Manipulating the lance from outside the process vessel will thereby cause the atomized spray of the fibrous material to contact the wall of the process vessel thereby repairing the same.

The present invention is directed towards metallized carbon nanotubes, methods for making metallized carbon nanotubes using an electroless plating technique, methods for dispensing metallized carbon nanotubes onto a substrate, and methods for aligning magnetically-active metallized carbon nanotubes. The present invention is also directed towards cold cathode field emitting materials comprising metallized carbon nanotubes, and methods of using metallized carbon nanotubes as cold cathode field emitters.
Abstract:
The invention provides a method for suppressing insufficient spread of droplets or mixing of the droplets in neighboring regions when a liquid material is disposed in the regions on a substrate by ejecting the droplets composed of the liquid material. In addition, for a display device, the structure in which insufficient spread of droplets or mixing of the droplets in neighboring regions can be suppressed and the manufacturing method therefor are provided. To accomplish the above, substantially square regions can be formed by a partition provided on a substrate. In each region, among internal surfaces and of the partition surrounding this region, the internal surfaces forming the long sides of the region have irregularities. In addition, the distance between parts of the partition opposing each other with one of regions provided therebetween is increased and decreased along the long side of the region. Furthermore, along the long side of the region, the width of the partition will be increased and decreased.
Abstract:
There is disclosed a composition for forming a protective coating upon a substrate. The composition has been found particularly useful for forming a protective coating upon components of automotive vehicles, such as a bedliner for a pick-up truck. The composition may include, without limitation, an isocyanate component and an amine component and optionally includes one or more of a catalyst, stabilizer, pigment, fire retardant or other additives.
Abstract:
The invention is generally directed to techniques for reducing premature drying of solvent-based coatings, including premature drying at sites on the apparatus that applies the coatings. By introduction of solvent vapor proximate to the coating apparatus, and by passively bringing the solvent vapor to the site, the risk of premature drying is reduced. In the presence of the solvent vapor, solvent in the coating fluid tends not to evaporate quickly. The solvent vapor may be introduced by any of a variety of solvent vapor emission devices, and may be brought to the site passively by, for example, increasing the concentration of solvent vapor in a boundary layer that moves with the substrate being coated, diffusion, or natural convection.
