| 20110152405 | Diene Rubber Composition for Tire Including a Silica as a Reinforcing Filler - A diene rubber composition for tires based on at least (i) one diene elastomer, (ii) one reinforcing inorganic filler and (iii) one coupling agent which provides the bonding between the inorganic filler and the elastomer. The inorganic filler comprises at least one silica capable of being obtained by the preparation process of the type comprising the reaction of a silicate with an acidifying agent, whereby a silica suspension is obtained, followed by the separation and the drying of this suspension. The reaction of the silicate with the acidifying agent is carried out according to the following successive stages: (i) an aqueous suspension of precipitated silica, exhibiting a pH of between 2.5 and 5.3, is brought into contact (mixing) with acidifying agent and silicate, in such a way that the pH of the reaction medium is maintained between 2.5 and 5.3, (ii) silicate is added to the reaction medium obtained, so as to increase the pH of the reaction medium up to a value of between 4.7 and 6.3. | 06-23-2011 |

| 20090294418 | Device for the Weld Joining of Sheet Metal Strips - A device for the laser weld joining of sheet metal strips includes the following elements: a main frame, a laser welding unit including a laser beam generator for welding the sheet metal strips to be joined and a welding head, a clamping jaw unit supported by the frame and used to clamp the sheet metal strips, and a shearing unit for shearing the head and tails of the sheet metal strips to be joined. The shearing unit includes upper blades mounted to a blade holder and lower blades which can move in relation to the upper blades and which are designed to shear a strip, as well as a blade connecting structure fixed to the frame, the above-mentioned welding head being mobile between the blade holder and the lower blades. | 12-03-2009 |
| 20110032540 | POSITION-MEASURING METHOD AND DEVICE ADAPTED FOR THE POSITIONING OF A WHEEL - A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position. The measuring position is vertically below a reference wheel. The reference wheel is continuously vertically lowered so that its lower surface comes into contact with the rotary roller and produces a bearing force on the roller. The roller is continuously moved in the direction of lowering. A distance between an index, which is secured to a measuring arm of the frame, and an articulated column of the frame is repeatedly measured during the continuous movement. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position in which the distance is equal to a predefined factor of the distance threshold. The first operating position is recorded as a reference point in a system for the vertical movement of the reference wheel. | 02-10-2011 |
| 20130037530 | MACHINE FOR JOINING THE ENDS OF STEEL STRIPS WHICH MACHINE IS SUITED TO THE INDUCTION HEAT TREATMENT OF JOINING WELDS - A joining machine for joining ends of successive strips in a strip treatment installation includes a device welding a first end of a strip to a second end of another strip, a first pair of symmetrical clamping jaws including a first upper and a first lower clamping jaw gripping the first end of a strip, a second pair of symmetrical clamping jaws including a second upper and a second lower clamping jaw gripping the second end of a strip, the clamping jaws holding and positioning the first end facing the second end for welding the ends together. At least two clamping jaws of the two pairs each include a part for contacting one of the ends to be welded to another end. The part has a geometry and at least one constituent material reducing a strength of eddy currents likely to be created in the clamping jaw by electromagnetic induction. | 02-14-2013 |
| 20140197141 | SAFETY CONFINEMENT EQUIPMENT FOR LASER RADIATION - Safety confinement equipment for laser radiation includes a safety confinement enclosure having two laterally opposite openings through which at least one metal strip can pass, the enclosure including first and second jaw devices for clamping the strip disposed on a path of travel of the strip between the two openings, the jaws being transversely disposed at least over the width of the strip. A cutting or welding equipment head emits a beam of laser radiation to be confined, in which the beam can be moved transversely between a pair of jaws disposed opposite each other on one side of a surface of the strip. In the position in which the jaws clamp the strip, the engagement of the jaws on the surfaces of the strip induces the formation of a physical screen against the laser radiation, which prevents the radiation from passing through the two openings of the chamber. | 07-17-2014 |
