20110235679 | FASTENING APPARATUS WITH ENGINE AND CARTRIDGE THERMISTORS - The fastening apparatus for fastening elements includes a combustion chamber, a housing for a gas cartridge, means for injecting gas from a cartridge into the combustion chamber and a management module. An engine thermistor is provided to be subjected to the temperature of the chamber, as well as a second cartridge thermistor intended to be subjected to the temperature of the gas cartridge disposed in the cartridge housing. Both thermistors are mounted for transmitting their temperature information to the management module. The management module is operable for managing temperature information and determining the opening time of the injection means. | 09-29-2011 |
20120090155 | METHOD OF FASTENING A GUARD RAIL BY MEANS OF A GUARD RAIL BOLT, THE GUARD RAIL BOLT AND THE TOOL FOR FASTENING THE GUARD RAIL BOLT - A self-expanding and self-undercutting guard rail bolt includes a dowel having a guard rail fastening end and a ring. The fastening end is configured to be driven in rotation, and the ring is configured to rigidly connect to a first screwing end of the dowel by an incipient fracture portion. The self-expanding and self-undercutting guard rail bolt further includes a counter-dowel screwed to the dowel by a second screwing end. The counter-dowel includes an expansion cone, and an anti-rotation head having at least one edge which projects beyond a periphery of the dowel to prevent rotation of the counter-dowel about an axis of the guard rail bolt. | 04-19-2012 |
20120097727 | FASTENING TOOL FOR FASTENING MEMBERS WITH A FUEL INJECTOR - The fastening tool comprises a system for controlling the intake of a fuel into a combustion chamber, a source of fuel, a switch for igniting said fuel in said combustion chamber. A valve, normally closed, comprises an intake port arranged for communicating with said source of fuel and an exhaust port arranged for communicating with said combustion chamber. The valve is a piezoelectric injector arranged for pressurizing the fuel at the outlet thereof and thereby micronizing it. | 04-26-2012 |
20140011117 | ADAPTER FOR CONNECTING A FUEL CELL AND A FUEL RESERVOIR FOR AN ELECTROPORTABLE DEVICE, A CELL AND ADAPTER ASSEMBLY AND THE DEVICE - An assembly of a fuel cell for an electroportable device and of a connection adapter for connecting the fuel cell and a fuel reservoir, the adapter being arranged for receiving a member for supplying the cell and an ejection nosepiece of the reservoir, the adapter comprising a valve arranged for being actuated by the ejection nosepiece of the reservoir and switched from a plugging condition, before connection, to a fuel transmission condition, after connection. | 01-09-2014 |
20140069981 | COMBUSTION FASTENING TOOL HAVING LOCK FEATURES - A gas setting tool, wasting a limited amount of fuel. The tool comprises i) an internal combustion engine, with a device for injecting fuel in the chamber of the engine, comprising a check valve and an injection piston, the injection piston extending beyond the check valve, and iii) a sealing joint mounted on the injection piston of the check valve. The injection piston comprises an internal bore opened on the exterior and the check valve and its injection piston are arranged so that, in an opening position, the fuel in a container is able, outside the check valve, to only flow through the internal bore of the injection piston. Thanks to this invention, fuel waste is reduced to the best. | 03-13-2014 |
20150047608 | REMOVABLE ADAPTER FOR AIR AND FUEL INTAKE AND MIXING IN A COMBUSTION TOOL - According to the invention, the adapter is arranged to be mounted in the tool, to be connected to a fuel cartridge and to receive fuel and communicate with a combustion chamber so as to inject a mixture of external air and fuel therein. | 02-19-2015 |
20150343625 | ELECTROPNEUMATIC GAS FASTENING DEVICE - A gas fastening device comprising an internal combustion engine with a combustion chamber arranged between, on the one side, an upstream compression piston and, on the other side, a downstream propulsion piston, intake means to inject into the chamber a mixture of air and a fuel, means being provided to fire a mixture injected into the chamber, both pistons being mounted mobile into translation for the intake of a mixture into the chamber and, after firing a mixture, for the driving of the fastening element by the downstream propulsion piston. | 12-03-2015 |
