20100147048 | Devices, Systems and Methods for Automated Wire Bending - Devices, systems and methods are disclosed which relate to a wire bending apparatus capable of both on and off-plane nose and mandrel bends. Exemplary embodiments of the present invention incorporate a center turret cluster with a plurality of radii possible, a nose-bending mandrel, and a mandrel-bending mandrel. This apparatus forms a bending head that is attached to a CNC wire bending machine. This combination allows increased flexibility in forming complex wire forms and cuts down secondary operations, such as operations from robot arms, sometimes associated with CNC wire bending. In addition, the turret cluster position in the center allows for bending support with mandrel bends or nose bending on the back side of the bending head, usually 180 degrees away from the normal bending area. This allows the manufacturing of double end-loop forms without the addition of external clamps or robotic manipulation. | 06-17-2010 |
20120217709 | Devices, Systems and Methods for Securing a Stake - Devices, systems, and methods are disclosed which relate to a stake that is twisted into and out of the ground via an adaptor. The adaptor adapts the stake to a power drill, allowing the power drill to twist the stake into and out of the ground by activating the drill. The adaptor is designed to fit a standard drill chuck at one end. At the other end, the adaptor has a fitting to receive the stake. The fitting is such that the stake and adaptor are axially locked so that the stake and adaptor rotate in unison when the drill is activated. The stake is a wire designed in a coil shape with a pilot. The pilot is fit into the adaptor which axially locks the stake with the adaptor. | 08-30-2012 |

20130122327 | APPARATUS AND METHOD FOR IMPARTING SELECTED TOPOGRAPHIES TO ALUMINUM SHEET METAL - A method for surface treating work rolls to produce isotropic textured aluminum sheet features shot-peening the surface of the working rolls that produce the sheet. The media may be steel balls, such as ball bearings or other media, such as glass or ceramic balls, depending upon the optical properties desired for the aluminum sheet, e.g., in terms of diffuseness or brightness of reflection. The various parameters of shot-peening can be varied to accommodate given properties of the roll, such as hardness and existing surface texture to achieve a given desired surface texture. A sheet surface with target properties and the work roll processing needed to produce it may be generated by computer modeling. | 05-16-2013 |

The spherical media can be introduced into a nip between two rolls and indent by compression, but ultrasonic peening or knurling. The aluminum sheet produced by the roll has properties that facilitate mechanical forming, such as when the sheet is processed by forming tools. | 10-17-2013 |
