Title: Ttl exploration technique for determining capabilities and configuration of a peer router
Inventor: COOK DAVID ANTHONY
IPC: H04L12/56
Filed: 2004-09-16
Granted: 2012-11-13
Abstract: An exploration technique allows a router to efficiently determine capabilities and configuration of a neighbor (peer) router. In addition, the technique enables peer routers of an adjacency to negotiate a capability "outside" of a protocol, such as a rout~ing protocol, before a routing session is established between the routers. In this con~text, the term "outside" of the protocol denotes that there is no field within a protocol packet (message) implementation that can be used to negotiate the capability. More~over, the inventive technique obviates the need to manually configure a router to sup~port a particular capability and interoperate correctly within a network of routers that both support and are unaware of the capability.

Abstract: An Nb-Ti-Co alloy having both good hydrogen permeability and good hydrogen embrittlement resistance comprises one of Fe, Cu or Mn as a fourth element, incorporating from 1 to 14 mol%. The content of Mn, if any, is preferably from 1 to 9 mol %. The desired hydrogen permeability can be attained by the (Nb,Ti) phase and the desired hydrogen embrittlement resistance can be attained by the CoTi phase, making is possible to obtain excellent hydrogen permeability and excellent hydrogen embrittlement resistance. None of Fe, Cu or Mn can impair these properties. Fe, Cu or Mn can replace some of the Co elements. Fe, Cu or Mn enhances the workability of the alloy.

Granted: 2010-05-18
Abstract: A method and apparatus in a wireless communication network for providing and maintaining authentication credentials required for a common data application accessible through the wireless communication network. The wireless portable communication device has default authentication credentials for the common data application. When it receives a data session configuration file including authentication credentials based upon a predetermined condition, it prioritizes between the default authentication credentials and the received authentication credentials, and uses the authentication credentials with the higher priority. The wireless communication network maintains the current authentication credentials and transmits a data session configuration file having the current authentication credentials upon detecting a predetermined condition. The wireless communication network allows proper access to the common data application upon receiving the current authentication credentials.

Title: Crop oil concentrate adjuvants containing amine surfactants
Inventor: TANN R SCOTT
IPC: A01N25/04
Filed: 2005-03-03
Granted: 2013-06-25
Abstract: In agricultural practice it is known to use emulsifiable oils (commonly referred to a Crop Oil Concentrates, COC ) as bioefficacy enhancers for pesticides, especially herbicides. Cationic surfactants are widely known to be particularly effective bio-active enhancers for herbicides, especially for glyphosate-type herbicides. The present invention includes two novel aspects:  1) While the vast majority of COCs are petroleum-based paraffinic oils or esterified seed oils, this invention embodies a new oil phase, a hydrocarbon oil such exemplified by EXXON-MOBIL'S D-130, which when combined with the surfactants described herein, exhibits surprising enhancement of herbicidal activity in field tests; and 2) COC's are designed to form stable emulsions in water. The combination of cationic surfactants and phosphate esters in this invention not only form very stable emulsions in water, but, surprisingly, also form extremely stable emulsions in concentrated liquid fertilizers, including 32-0-0 fertilizer.

Title: Printing paper winding device
Inventor: KOJIMA MASAHIRO
IPC: B41J15/16
Filed: 2005-12-26
Granted: 2009-03-17
Abstract: A printing paper winding device for enabling winding of printing paper even paper with a base material having a low resistance to bending stresses or printing paper having RFID labels carrying IC chips. Bending stresses are reduced by dividing the movement region of the tension roller into four regions in order to enable the successive detection of the position or posture of the tension roller and by making the bending angle of the printing paper in the winding path close to a more obtuse angle. A winding control unit of the present invention determines whether the tension region where the tension roller is positioned is a first tension region, second tension region, third tension region, or fourth tension region, controls the drive unit to limit the tension roller to a tension region in which winding is possible in the direction such that the bending angle of the printing paper in the winding path, which follows the winding of the printing paper, is close to a more obtuse angle.

Title: Process for manufacturing a part of a metal matrix composite material
Inventor: NAKAO YASUHIRO
IPC: B32B15/20
Filed: 2001-05-04
Granted: 2010-11-09
Abstract: A part is manufactured from a composite material containing an aluminum alloy as a metal matrix. Blanks are prepared from a billet of the composite material, and worked on in a press, while they are held at a temperature ranging from the solidus temperature, Ta, of the aluminum alloy minus 50 (Ta - 50) deg. C to Ta deg. C. At a temperature below (Ta - 50), the blanks have too high a resistance to plastic deformation to be easily worked on. At a temperature over Ta, a liquid phase is produced and makes the blanks likely to crack easily during plastic deformation. At the specified temperature range of Ta-50 deg. C these problems are avoided and improvements in manufacture are realized.

Abstract: Compositions and methods for improving demolding polar resin molds used in the production of silicone hydrogel materials are described. The present compositions and methods include the use of one or more reactive demolding agents. The reactive demolding agents react with components of a polymerization mixture to produce a polymerized silicone hydrogel device containing a reactant product of the demolding agent and the other components of the polymerization mixture. Polar resin molds used during the polymerization of the polymerization mixture are more easily separated than substantially identical molds used in the polymerization of a substantially identical material without a reactive demolding agent. The present compositions and methods may be used in the manufacture of silicone hydrogel lenses, such as contact lenses. The demolding aids may also be useful as delensing aids.
