Title: Slow rotating tool with gear reducer
Inventor: TUCKER JAMES C
IPC: F16H1/32
Filed: 2000-08-02
Granted: 2007-03-13
Abstract: A slow rotating apparatus for use in performing downhole operations. The apparatus generally consists of a motor section with a rotor rotatable in response to fluid flow, a speed reducer section connected to the motor section such that an output speed of the speed reducer section is less than an output speed of the rotor, and a jetting section or other head attached to the speed reducer section and rotated thereby at the speed reducer output speed. A flow passage is defined through the speed reducer section so that fluid may communicate therefrom into the jetting head. The speed reducer section includes an input shaft attached to the rotor.      The input shaft has an eccentric portion and has an input gear disposed about the eccentric portion. The input gear is a solid gear having a first outer geared surface and a second outer geared surface. The pitch diameter of the first outer geared surface is less than the pitch diameter of the second outer geared surface. A speed reducer body has a geared inner surface defined thereon in geared engagement with the first outer geared surface. A follower gear is disposed in the body and is in geared engagement with the second outer geared surface. Rotation of the input shaft causes the eccentric portion thereof to rotate in the input gear causing eccentric rotation of the input gear. Eccentric rotation of the input gear is translated into pure rotation by the follower gear which rotates the output shaft.

Abstract: An edible anhydrous chocolate-based fat system is provided, having a significant granulated sugar component. This provides an unusual mouth sense, and allows for significantly different organoleptic properties of the chocolate-based fat system - which otherwise emulates chocolate. The chocolate may be light or dark, or white chocolate. An additional sweet flavor may be added to the chocolate-based fat system, allowing for a faster release of the additional flavor, by infusing or saturating the granulated sugar component of the fat system with the additional flavor. Typically, the granulated sugar component is saturated with an essential oil of a chosen flavor. Apart from the granulated sugar component, the remaining ingredients of the chocolate-based fat system are conched in the usual manner in keeping with chocolate production techniques. A process for production of the edible anhydrous chocolate-based fat system is discussed, and typical machinery for carrying out that process is shown.

Title: Arbitration method for high power transmissions in a code division multiple access system
Inventor: PROCTOR JAMES A JR
IPC: H04W52/50
Filed: 2000-01-14
Granted: 2010-06-08
Abstract: In an interference mitigation method, subscribers that will receive a high power transmission generate an alert message to surrouning base stations. A surrounding base station, before it generates new transmissions, determines the distance between it and a second subscriber that will receive the new transmission. If the distance is greater than an interference threshold, the base station delays the new transmission until the first high-power transmission concludes. The method prevents two high-power transmissions from occurring simultaneously.
