  • Patent number: 8389066
    Abstract: An innovative method of prepping a surface entails entraining a coating particle into a fluid stream, directing the fluid stream containing the coating particle at the surface to be prepped to thereby prep the surface using the coating particle. The prepped surface can then be coated using the same or substantially similar coating particle. This method can be used with a continuous airjet, a forced pulsed airjet, a continuous waterjet or a forced pulsed waterjet as the carrier stream. This invention solves the problem of foreign blasting particles becoming embedded in the atomic matrix of the surface to be prepped, which can result in unpredictable behavior of the surface properties and even catastrophic failure.

  • Publication number: 20090181176
    Abstract: Method and arrangement for separating impurities from the machine circulation of a processing agent of a processing station used in processing paper or board, in which method the processing agent is led from a reservoir (1) to the processing station (2), where it is spread on the surface of the web being processed, and the excess processing agent led to the processing station (2) agent is led back to the reservoir (1). The flow of processing agent coming from the processing station (2) is led to at least one pressure sieve (6), which is located below the level of the processing station (2), in such a way that the feed pressure of the processing agent is created on the basis of the difference in height between the station (2) and the pressure sieve (6).

  • Publication number: 20090061207
    Abstract: Apparel us for impregnating a porous substrate (e.g., wood) with an active agent, including a reservoir for containing a low boiling fluid, a controllable first fluid pathway to permit fluid to flow from the reservoir to a treatment vessel, a fluid junction for introducing the active agent into the first fluid pathway to permit mixing of the active agent with the low boiling fluid to produce an impregnation fluid containing an initial level of active agent and a controllable second fluid pathway to allow fluid to flow from the treatment vessel to the reservoir. The treatment vessel contains the porous substrate while it contacts the impregnation fluid in a liquid state to produce a treated substrate impregnated with the active agent.

  • Patent number: 7435447
    Abstract: In a high pressure processing system configured to treat a substrate, a flow measurement device is utilized to determine a flow condition in the high pressure processing system. The flow measurement device can, for example, comprise a turbidity meter. The flow parameter can, for example, include a volume flow rate or a time to achieve mixing of a process chemistry within a high pressure fluid used to treat the substrate.

  • Patent number: 7419699
    Abstract: The present invention is a CVD process for forming a thin film which includes a step of recovering an organometallic compound component from an exhaust gas which has been conventionally discarded, and a purifying step of purifying the recovered organometallic compound to thereby eliminate a by-product formed in a film forming step by CVD. According to this process, the organometallic compound is recycled. As a recovering technique, any of the followings is employed: a technique in which the exhaust gas is cooled and is recovered as a recovered content; a technique in which the exhaust gas is brought into contact with a solvent to dissolve the organometallic compound in the solvent; and a technique in which the exhaust gas is brought into contact with an adsorbent to thereby adsorb the organometallic compound.

  • Patent number: 7325750
    Abstract: Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator. The powder falls into a transfer pan and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver. The powder is then discharged to the feed hopper in the feed center. The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line cleaned by one or more cleaning elements drawn through the vacuum line.

  • Patent number: 7290589
    Abstract: Material is incrementally deposited using material directed toward a deposition zone. The scan path of the directed material is controlled according to a path plan derived to reduce derivation from an ideal uniform temperature profile for the deposition during the deposition process. A path plan having angled scan passes that intersect (or overcross one another), for example in a mirrorbox path plan, is preferred.

  • Patent number: 7022380
    Abstract: Method and apparatus for coating a traveling paper web includes a coater head. The coater head includes an inlet for receiving fresh coating material which is introduced into a mixing chamber. A looped flow path is established within the coater head which includes a feed channel extending from the mixing chamber and leading into a coating chamber where one portion of the coating material proceeds in the direction of the rotating backing roll. The aqueous slurry of coating material near the downstream end of the coating chamber enters a recirculation channel from which it is directed through a plurality of flow metering orifices back into the mixing chamber.

  • Patent number: 6926923
    Abstract: There is provided a method of forming a coat on an inner surface of a bearing, in which a jig 13 is attached to a rotor 2 while holding four bearings 12 for example, so as to form those in a cylinder shape. Then, while the rotor 2 is rotated at a circumferential speed of 0.3 m/sec, a nozzle 8 for airless spraying is inserted into the rotor 2, so that the nozzle 8 injects a coating material 30 from the inside of the bearings 12 toward an inner surfaces of the bearings 12 to apply the coating material thereon. Because the coating material 30 is injected from the nozzle 8 without using compressed air, the fly amount of the coating material is made less as compared to air spray painting.
