Patent number: 8256092Abstract: A tool may be used to form an engine cylinder bore in a compacted graphite iron workpiece using helical interpolation. The tool may be rotated about a first axis while orbiting about a second axis that is parallel to the first axis. While rotating and orbiting, the tool may be advanced into the workpiece. This helical interpolation may be used to successively engage cutting or honing elements of the tool with the workpiece. The elements may thereby be permitted to cool between each successive engagement, which may reduce wear on the tool. Various operating parameters associated with the process may have certain relationships that may be exploited in certain ways to obtain ideal results. For instance, a helical interpolation process may be used to perform an act of rough cutting on the workpiece and finish honing on the workpiece, without having to perform an intermediary step of semi-finish boring.Type: GrantFiled: January 30, 2009Date of Patent: September 4, 2012Assignees: Makino Inc., AB Sandvik CoromantInventors: David C.

For example, the composite portion may include fibers that constitute at least 50% by volume, fibers that are at least 30 mm in length on average and/or fibers that are within 15° of being parallel to the longitudinal axis of the handle.Type: GrantFiled: May 29, 2008Date of Patent: September 4, 2012Assignee: Leatherman Tool Group, Inc.Inventor: Charles F. Goodrich

Patent number: 8256122Abstract: A two part scraper for scraping glass and other substrates, wherein a scraping part may be located on one side of the substrate and a handle member may be located on the other side. The two parts are magnetically coupled and move in tandem when the handle part is pulled by the user. A cutting blade may be received within a blade holder which may be mounted to the scraping part by screws and coil springs. The blade holder may be mounted at an angle such as a forty-five degree angle to the surface being scraped. The scraping part may comprise hook and loop material as a scrubbing surface and may have a suction cup located on that surface contacting the substrate. The handle part may have a soft felt lining for contacting the substrate.Type: GrantFiled: July 18, 2009Date of Patent: September 4, 2012Inventor: John T. Hatfield

Patent number: 8256123Abstract: Angular displacement of a flexible substrate is determined based on an electrical change of a mm-wave circuit associated with the flexible substrate. This electrical change may relate to, for example, one or more of a phase shift, an amplitude shift, a frequency shift, or a pulse shift. In some implementations the flexible substrate may include conductors on multiple layers whereby an angular displacement of the flexible substrate causes a relative displacement between conductors of different layers, thereby inducing the electrical change of the mm-wave circuit.Type: GrantFiled: March 24, 2009Date of Patent: September 4, 2012Assignee: Rambus Inc.Inventors: Fred S. Lee, Frank Lambrecht

Patent number: 8256124Abstract: A tilt sensor comprises a multi-layer circuit board, a holder, a first light-sensing component, a second light-sensing component, a light-emitting component, and a movable component. The multi-layer circuit board comprises a first layer board and a second layer board disposed on the first layer board. The second layer board comprises first, second, and third holding spaces each of which exposing a respective portion of the first layer board. The holder is disposed on the second layer board and has a containing recess connecting the first, second, and third holding spaces. A bottom surface of the containing recess is reflective. The first and second light-sensing components and the light-emitting component are disposed on the first layer board and in the first, second, and third holding spaces, respectively. The light-emitting component emits a light beam toward the bottom surface of the containing recess. The movable component is disposed in the containing recess.Type: GrantFiled: May 26, 2011Date of Patent: September 4, 2012Assignee: Everlight Electronics Co., Ltd.Inventors: Chao Hsuan Su, Chin Chia Hsu

Patent number: 8256125Abstract: The present invention relates generally to a sliding square that can be slipped over a standard retractable tape measure that is extendable perpendicularly to abutment wall allowing 0-90 degrees angle lines to be scribed at measured distances from the end of a work piece. Sliding Square also may include a depth gage, bubble levels on the x and y planes, a protractor scale along with linear dimensions along its right angle straight edge side and standard rafter pitch angles to be defined. Abutment wall t's into base 32 extending equally above and below base so that it functions right side up from the left side of a work piece or flipped over from the right side.Type: GrantFiled: December 14, 2009Date of Patent: September 4, 2012Inventor: Clifford J. Jarzynka, Jr.

Patent number: 8256127Abstract: A detecting apparatus is capable of detecting a vertical distance between a first axis and a second axis on a workpiece. The detecting apparatus includes a supporting plate, a first positioning member, a second positioning member, and a measuring member. The first positioning member and the second positioning member are arranged on the supporting plate along the first axis, and fix the horizontal position of the workpiece. The measuring member is arranged on the supporting plate along the second axis, and is capable to slide along the second axis. The measuring member is able to pass a bottom hole of the workpiece if the workpiece is qualified, and is unable to pass the bottom hole if the workpiece is not qualified.Type: GrantFiled: August 31, 2011Date of Patent: September 4, 2012Assignees: Hong Fu Jin Precision Industry (ShenZhen) Co., Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Bing-Jun Zhang

Patent number: 8256130Abstract: A way to safely fry turkeys by minimizing the hazard of overfilling oil, the Turkey Frying Oil Gauge (TFOG) comprises a device and method to properly pre-measure the frying oil used to fry whole turkeys. The Turkey Frying Oil Gauge is duel scale selectable for pot diameter and turkey weight. The turkey frying pot rim is measured and the size is selected on the gauge bottom. The mast is then slid out to view the weight of the turkey to be fried. The gauge is then placed in the bottom of the pot and frying oil is placed in the pot to the top of the gauge. The oil gauge is removed, the oil heated and the turkey introduced without overflowing the oil onto the heating flames.Type: GrantFiled: November 30, 2009Date of Patent: September 4, 2012Inventor: Edward Lee Jantz
