  • Method and installation for making a workpiece comprising at least a tubular section
    Patent number: 6988390
    Abstract: A method of forming a tubular workpiece which consists in pre-bending a metal plate along at least two longitudinal lines of bend (12–13) then in bending the plate along at least one of the lines of bend (12–13) using a bending member (103–104) that exerts an external clamping force (F7, F8) along a part (23, 24) of the plate towards the at least one of the lines of bend (12, 13). Thereby preventing any sliding of part (23, 24) of the plate along the bending member (103–104) as the bending member bends the part. The bending member is articulated about a virtual geometrical axis (a, c) located inside a tubular section of the workpiece.

  • Heddle, heddle frame and weaving loom equipped with such a frame
    Patent number: 6981527
    Abstract: The heddle according to the invention is provided at the level of each of its ends with at least two sections for simultaneous bearing on corresponding surfaces formed on a traction bar fast with a crossbeam of a heddle frame. These sections and surfaces allow the transmission of an effort of traction exerted by one of the crossbeams on the heddle. They are offset in a direction substantially parallel to a longitudinal axis of the heddle and to an axis of the uprights of the frame.

  • Method and device for performing secure transactions
    Patent number: 6948061
    Abstract: A certificate validity verification engine is integrated into the logic of a secure token, in turn, making the use of a private key conditional upon the determination that the certificate for the corresponding public key is valid at that particular instant in time. In this manner, the existence of a digital signature that is verified with a certificate implies that the certificate was valid at the time the signature was created. The verification of the certificate's validity by the relying party is unnecessary, as the signature could not have been created had the certificate been invalid. The validity of a certificate is communicated at the time the signature was created, rather than at the time the signature was verified.

  • Feeding apparatus for cellulosic material
    Patent number: 6945487
    Abstract: An apparatus for pressure tight discharge of refiner material, such as cellulosic material by using a screw which feeds the material between a screw shaft and screw housing whereby a pressure tight material plug is formed at an outlet of the screw housing. The screw is, at the out end, provided with a flange which together with a throttle journalled around the flange forms an adjustable outlet opening through which material is fed out by the screw while the material forms a pressure tight material plug.

  • Rotating dobby for weaving loom and weaving loom equipped with such a dobby
    Patent number: 6938647
    Abstract: The dobby according to the invention comprises, at the level of each of its blades, an oscillating piece associated with an actuation element, at least one mobile coupling member borne by the actuation element and two pivoting levers subjected, on the one hand, to the action of a reading device and, on the other hand, to that of elastic means which tend to engage catches of the pivoting levers either with a jamming surface provided on the actuation element, or with the coupling member, while the lever in engagement with the jamming surface is out of range of a selector of the reading device. In addition, mechanical members independent of the reading device are adapted to displace, against the action of the elastic means, a lever whose catch is not in engagement with the jamming surface, with the result that it does not interfere with the angular displacement of the selector.
