Patent number: 8011602Abstract: Many areas watered by prior art oscillating sprinklers are substantially rectangular. However, prior art oscillating sprinklers typically produce generally or substantially elliptical water distribution patterns. This geometric incompatibility causes problems and inefficiencies. Embodiments of the current invention include an oscillating sprinkler that automatically produces a substantially rectangular water distribution pattern. The substantially rectangular water distribution pattern may be produced by automatically controlling the distance from the sprinkler that streams of water travel before impacting the ground. This is accomplished by automatically and sequentially opening and closing and/or restricting flow to select nozzles at select points and within select portions of the oscillation cycle. A current invention oscillating sprinkler may reduce waste water, may reduce run-off waste water, and may automatically provide water to the corner areas of typical substantially rectangular areas to be watered.Type: GrantFiled: August 15, 2008Date of Patent: September 6, 2011Inventor: Eldon Coppersmith

Patent number: 7789320Abstract: A safety drinking straw includes a beverage delivery tube having a tube first end for insertion into a quantity of beverage and a tube second end for placement between user lips; and a debris blocking structure substantially at the tube first end permitting a free flow of the beverage through the delivery tube while preventing entry of debris of a selected minimum target size into the delivery tube; so that the debris blocking structure prevents debris from entering the delivery tube and thus prevents debris from lodging and becoming an obstruction within the delivery tube. The debris blocking structure preferably includes at least one cord extending across the interior of the delivery tube substantially at the tube first end, and alternatively includes at least one tube partition or at least two tubular barrels fitted longitudinally and in tandem inside and secured within the delivery tube.Type: GrantFiled: June 1, 2006Date of Patent: September 7, 2010Inventor: Jason P. Schwartz

Patent number: 7792611Abstract: The purpose of the invention is to provide a method to characterize a spray pattern by detecting and quantifying asymmetries resulting in detailed information on location, size, and type of asymmetries within the spray pattern, which are important for spray characterization comparability and classification. A system is provided for in-situ monitoring of the spray characteristics.Type: GrantFiled: October 3, 2005Date of Patent: September 7, 2010Inventor: Ingo Werner Scheer
