U.S. Patents Awarded to Inventors in Oregon (Sept. 12)(Targeted News Service Via Acquire Media NewsEdge) Targeted News Service Targeted News Service ALEXANDRIA, Va., Sept. 12 -- The following federal patents were awarded to inventors in Oregon. *** Oregon Inventors Develop Patent for Wind Driven Power Generator ALEXANDRIA, Va., Sept. 12 -- Donald R. Gradwohl, Albany, Ore., and Jonald R. Gradwohl, Corvallis, Ore., have developed a patent (8,011,876) for a "wind driven power generator." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A wind driven power generator has a rotational shroud assembly for maximizing wind input and a turbine assembly with a shaft that rotates within the shroud assembly. The shaft end extends through the base of the shroud assembly. The turbine assembly has elongate arms attached to the top portion of the shaft of the turbine assembly. Each arm is essentially perpendicular to the shaft and has a vertical wind blade attached to each of the arm ends and spaced equidistance apart around the shaft of the turbine assembly. The shroud assembly covers approximately half of the turbine assembly during rotation and maintains a windward direction for maximum wind on the blade fronts while shielding the back sides of the blades from the incoming wind." The patent application was filed on Oct. 25, 2006 (11/586,803).

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A projectile device having a suction cup head made of a novel foam. The foam used in the suction cup head has an open cell density within the foam of between five percent and twenty percent. The suction cup head has a face surface of a first diameter. A shallow concavity is formed in the face surface. The concavity has nearly the same diameter as the face surface, however, the depth of the concavity is no more than one-tenth of that diameter. Furthermore, the face surface of the suction cup head is proportionally large, being at least twenty-five percent as wide as the entire projectile device is long. The combination of a large suction cup head, a shallow concavity and a soft, semiporous foam enables the suction cup head to adhere to both smooth surfaces and rough surfaces." The patent application was filed on July 2, 2008 (12/167,223).

The co-inventors are Benno Orschel, Salem, Ore., Joel Kearns, Springfield, Va., Keiichi Takanashi, Saga, Japan, and Volker Todt, Lake Oswego, Ore. The abstract of the patent published by the U.S. Patent and Trademark Office states: "An improvement to a method and an apparatus for growing a monocrystalline silicon ingot from silicon melt according to the CZ process. The improvement performs defining an error between a target taper of a meniscus and a measured taper, and translating the taper error into a feedback adjustment to a pull-speed of the silicon ingot. The conventional control model for controlling the CZ process relies on linear control (PID) controlling a non-linear system of quadratic relationship defined in the time domain between the diameter and the pull-speed. The present invention transforms the quadratic relationship in the time domain between the diameter and the pull-speed into a simile, linear relationship in the length domain between a meniscus taper of the ingot and the pull-speed. The present invention applies a linear control (modified PID) which operates in the length domain, and controls a system that has a linear relationship between the ingot taper and the pull-speed in the length domain to control the diameter of a growing silicon ingot." The patent application was filed on July 31, 2008 (12/184,016).
