20100038444 | Oscillating Sprinkler that Automatically Produces a Rectangular Water Distribution Pattern - 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. | 02-18-2010 |
20110101123 | OSCILLATING SPRINKLER AUTOMATICALLY PRODUCING EVENLY-SPACED RECTILINEAR WATERING AND A RECTANGULAR WATERING PATTERN - A sprinkler includes an oscillating tube that receives water from a supply, and the tube oscillates about a longitudinal axis through a range of radial angles. A plurality of nozzles spaced along the oscillating tube distribute water generally upward and outward from the oscillating tube to create a water distribution pattern on the ground. The longitudinal angles of at least some of the nozzles are automatically selectively regulated as a function of the radial angle of the oscillating tube, controlling the impact locations on the ground of the water emanating from the respective nozzles. The longitudinal angles may be automatically regulated such that the water emanating from the respective nozzles reaches parallel, rectilinear, evenly-spaced impact locations on the ground. The ranges of radial angles traversed by at least some of the nozzles may be automatically regulated such that the ends of the water distribution pattern are rectilinear. A rectangular or square water distribution pattern may be thereby automatically produced. | 05-05-2011 |

20120205870 | Portable target apparatus - A portable target apparatus for use in target practice is provided. The target may be comprised of metal, for example steel. The target includes a base frame and a target plate that is attached to the base frame. Upon being struck by a projectile, the target plate rotates about the base frame into a knocked down position. One or more sensors sense the target is displaced into the knocked down position and a reset mechanism drives the target plate back to the initial position. The base frame of the target apparatus is of hollow construction, thereby making the target portable with relative ease. | 08-16-2012 |
20120263557 | License Plate Fastener - A license plate fastener assembly includes a female collar including an internally threaded cylinder and a radially outboard flared shoulder. A bumper is mounted on the shoulder. A bolt is compatibly received in the threaded cylinder. The bolt presents a bolt head to define a selectively adjustable distance between the bolt head and the bumper. One or more washers made or synthetic resin may be mounted on the cylinder for selective depth adjustment of the distance. | 10-18-2012 |
20130152435 | License plate frame pivoting fastener cover - A specialized fastener cover is suitable for concealing a fastener used to attach one object to another. The fastener cover includes a decorative emblem and a method of pivoting the emblem between two positions. In one position, the decorative emblem conceals the fastener. When the emblem is pivoted to the second position, the fastener can be accessed so that it can be inserted in fastener receptacles in the objects to attach the objects to one another or removed from the fastener receptacles to separate the two objects. The fastener cover can be incorporated into an attachable object, such as a license plate frame to be attached to a vehicle. | 06-20-2013 |
20130302108 | PIVOTING FASTENER COVER - A specialized fastener cover is suitable for attaching to a fastener used to attach one object to another. The fastener cover includes a decorative faceplate and a method of pivoting the faceplate between two positions. In one position, the fastener can be inserted into the two objects to hold the objects together, or can be removed from the objects to release them from each other. When the faceplate is pivoted to the second position, the decorative faceplate conceals the fastener. The fastener cover can be used to cover fasteners attaching a variety of objects to each other. | 11-14-2013 |
