Abstract: Système assurant la commande des gaz dans un véhicule composite commandé par un conducteur, ledit véhicule comprenant au moins deux moteurs dont chacun est actionné par un papillon indépendant. L'un des papillons est commandé par une pédale d'accélération normalisée tandis que l'autre est commandé par un accélérateur à commande manuelle. En cas de freinage d'urgence, le second moteur ne tient plus compte du second accélérateur, et est contraint à se mettre au ralenti. En outre, le second accélérateur ne peut redevenir actif que lorsqu'il est réinitialisé manuellement vers une position déterminée. Il s'agit généralement de la position de ralenti. Ce système trouve application dans les cas où le conducteur peut se voir contraint de procéder à un freinage d'urgence et n'est pas en mesure de commander l'accélérateur à main afin de s'assurer que le second moteur ne continue pas à entraîner le véhicule. Un perfectionnement supplémentaire de l'invention réside dans le fait que, lors d'un freinage d'urgence, le système de transmission accouplé au second moteur, qui est le plus souvent automatique, est contraint à se mettre en mode transformation afin de protéger la transmission de toute dégradation.

Abstract: In a method for joining at least two plate-shaped workpieces by a fastening tool and a device for operating the fastening tool, the fastening tool comprises a punch for exerting a punch force to perform a joining operation and a clamp for exerting a clamping force upon the workpieces at the joining area. During the joining operation the punch exerts a high punch force to perform the joining operation and the clamp exerts substantially no clamping force to allow for free material deformation in the joining area. After the joining operation both the punch and the clamp exert high forces at the same time to reduce any material deformations of the workpieces and to provide for compression of the workpieces in the joining area.   Preferably the invention is used in a riveting tool for setting self piercing rivets; as an alternative it may be used in a clinching tool.

Filed: 2004-02-02
Abstract: The invention provides methods for identification and determination of target-specific sites in peptides and proteins, including a method for determining the primary sequence of a secondary structure within a known parent polypeptide that binds to the target of interest. In one embodiment of the invention, a residue or mimetic containing a nitrogen atom and a sulfur atom available for binding to a metal ion is serially substituted for single residues in or inserted between adjacent residues in a known primary sequence of a peptide or protein. The resulting sequence is complexed with a metal ion thereby forming a metallopeptide. The resulting metallopeptides are then used in binding or functional assays related to the target of interest, and the metallopeptide(s) which result in significant or substantially decreased or changed binding or functionality are determined to identify the primary sequence involved in such binding or functionality.

Abstract: The invention relates to a method and an assembly for compensating the temperature of circular resonators with dual-mode function consisting of a material with a low thermal expansion coefficient, in which tractive or compression forces are transmitted to the resonator wall, producing elastic deformations. According to the invention, the resonator wall (1) is deformed at one or more points along its axial extension in two directions that are perpendicular to one another by a respective identical absolute value, the deformation forces being directly introduced into the resonator wall (1) by means of at least one flange (2). The advantage of this is that the peripheral form of the circular resonator casing is deformed in such a way that both orthogonal dual modes are subjected to a uniform shortening during a simultaneous expansion of the material, thus achieving a significant compensatory effect.
