  • Patent number: 5942336
    Abstract: A method for recycling contaminated flush water from a wet electrostatic precipitator emission control system in a wood panel fabrication process. The recycled flush water containing solid byproducts from the emission control system is combined with wood products in a wood panel fabrication mix in a predetermined ratio of flush water to wood products, resulting in a finished wood panel having improved internal bond strengths and formaldehyde scavenging capacity without the need for excess binding resins and formaldehyde scavengers.
    Type: Grant

    Date of Patent: August 24, 1999

  • Patent number: 5285903
    Abstract: A thin film membrane filtration system recovers particulate from the waste water stream of a wood panel fabrication process to a desired concentration of approximately 30-50% solid by weight. The high concentration level enables improved transport or disposal. Rather than discard the concentrate, however, the concentrate is added into subsequent wood panel "particle board" batches at a rate of approximately 0.5 to 0.65 gallons per 1000 pounds of wood product. The concentrate reduces press time, serves as a scavenger for tying up formaldehyde and serves as a resin extender for strengthening internal bonds of fabricated panels. The membranes capture the particulate into an accumulated concentrate, while passing permeate output to a recycle water stream.

  • Patent number: 4729535
    Abstract: An assembly for supporting a cooking device, such as a barbecue, including a main platform and folding end platforms. The main platform is connected to a shaft which in turn is mounted to a conventional structure such as the rail of a boat by means of a mounting bracket. The support assembly which supports the cooking device thereon, is secured in a level manner above the ground or water. Repositioning of the main platform and end platforms relative to the mounting bracket is accompanied by slidably mounting the main platform to the support shaft. When it is desired to store the support assembly when not in use, the end platforms are folded inward to locations atop the main platform, the mounting bracket and shaft are moved inward toward the main platform, and the support assembly is stored inside the cooking device.
