  • Patent number: 6561674
    Abstract: Through the use of a variety of reinforcing structures, a ribbon light string is described that can be shaped in decorative ways, and it is made of a material that, due to its coloring and/or texture, can become camouflaged into its environment, or of a material that is preferably reflective and compliments the light from the lamp bulbs of the light string. Essentially, the ribbon light string is a reinforced ribbon having a passage therethrough for carrying substantially all, of the non-illuminating portion, of a light string while allowing the illuminating portion to be exposed. To facilitate the shaping of the ribbon, several embodiments are described including the use of pliable ribbon material; the use of at least one reinforcing wire running through the longitudinal extent of the passage; or the use of a “ribbon wire” type conductor for the light string. Also described are the use of novel hole and flap arrangements and lamp bulb/lamp base configurations.

  • Patent number: 6553133
    Abstract: A method and apparatus are provided by which a sheet-forming web may be characterized in four dimensions. Light images of the web are recorded at a point adjacent the initial stage of the web, for example, near the headbox in a paperforming operation. The images are digitized, and the resulting data is processed by novel algorithms to provide a four-dimensional measurement of the web. The measurements include two-dimensional spatial information, the intensity profile of the web, and the depth profile of the web. These measurements can be used to characterize the web, predict its properties and monitor production events, and to analyze and quantify headbox flow dynamics.

  • Patent number: 6536061
    Abstract: A method and system for separating oil form oil-absorbent materials for recycle of both the oil and the materials. The method comprises placing the oil absorbent material on a grid over a catch basin to drain, then centrifuging the material to remove additional excess oil. The excess oil is processed to separate water, grit, dirt, metal chips and shavings from it so that it can be sent to a refinery. After centrifuging to remove excess oils, the materials are dry cleaned in doubly distilled dry cleaning fluid to remove additional oil so that the materials can be reused.

  • Patent number: 6533790
    Abstract: A transpedicular screw having a round head and thin neck so that when the head encounters resistence, such as the harder cortex of a pedicle, it bends toward the softer axis of the pedical, thus avoiding violation of the pedicle cortex. The screw is inserted following the formation of a hole toward the pedical axis using a guide rod and a pin. Preferably this hole is made at an angle of approximately 35° with respect to the perpendicular and extends just to the pedical. The screw has a threaded body behind the neck and a tail formed to receive a tool that facilitates rotation of the screw into the pedical.
