20100316885 | Assembly method by reactive brazing and vacuum cartridge assembled according to this method - The present invention relates to an assembly method by reactive brazing of a first metallic element such as an end cover plate of a vacuum cartridge with a second element such as the cylindrical body of said cartridge, said second element comprising an ion-covalent oxide at least at the surface by means of an alloy called added alloy designed to constitute a liquid brazing alloy designed to wet the two respectively metallic and ion-covalent oxide surfaces to be assembled of the above-mentioned two elements, said brazing alloy containing titanium and said metallic element containing nickel. This method is characterized in that in the case where the percentage by weight of the alloy elements content of the metal which can form intermetallic compounds with titanium is less than 20%, the titanium content in the brazing alloy is comprised between 2% and 5% by weight, and in the case where the percentage by weight of the alloy elements content of the metal which can form intermetallic compounds with titanium metal to be assembled is comprised between 20% and 50%, this titanium content is chosen between 5% and 10%, and in the case where the percentage by weight of the alloy elements content of the metal which can form intermetallic compounds with titanium is more than 50%, this titanium content is chosen between 2% and 5% and the percentage by weight of Ag is less than 60% so as to minimize the non-wettability areas on the surface of the second element made from ion-covalent oxide by forming a sufficiently thick and stable reactional layer at the interface of said element, and to minimize formation of intermetallic compounds in the brazed joint. | 12-16-2010 |
20110084117 | Device for assembly by brazing an end cap onto a cylindrical body and vacuum cartridge comprising one such device - The present invention relates to a device for assembly by brazing an end cover onto a cylindrical body, said end cover presenting a circular peripheral rim via which said cover is brazed onto a part of one of the end surfaces of the cylindrical body, this device being characterized in that the above-mentioned cover is shaped in such a way that, on the above-mentioned end surface of the cylindrical body, the circular peripheral part of the above-mentioned cover exerts a compressive stress, after brazing, on substantially the whole contact area between the end surface of the cover and the end surface of the cylindrical body. | 04-14-2011 |

20110056327 | Steering and Braking Pedal Arrangement for Tractors - A tractor steer-by-braking pedal arrangement. The pedal arrangement has a central brake pedal connected on one side to a right side pedal, and on the other side to a left side pedal. The central brake pedal acts on a brake system to produce the desired braking action. Each of the two side pedals when foot-operated by the driver, generates an activating signal to activate an electronic brake system, which only activates the brake required to steer-by-braking in the desired direction. | 03-10-2011 |

20100116605 | Apparatus for the Parking Lock of an Agricultural Vehicle - An apparatus for the parking lock of a vehicle, in particular, of an agricultural tractor. The apparatus comprises a parking lever mechanically linked to a braking lever by a cinematic chain. The braking lever comprises a tooth apt to engage at least a braking element vehicle. The braking lever is provided with a yielding device placed in correspondence to its own hinge. The yielding device is able to ease the engagement of the tooth with a gap comprised between two teeth of a driveline gear in order to guarantee a reliable parking lock of the vehicle. | 05-13-2010 |
