Patent WO-0220853-A1 (WO)
Title: Procede permettant de fournir simultanement de l'energie et une isolation thermique a un bain de metal liquide
Inventor: COMINI PAOLO GIUSEPPE
IPC: C21C7/076
Filed: 2001-09-10
Abstract: La présente invention concerne, dans une première étape, un procédé de fourniture d'énergie et ensuite, un procédé d'isolation thermique destiné à la surface des bains de métal pour la fonte brute, l'acier, etc.  Dans les usines sidérurgiques intégrées, après que les hauts fourneaux ont été percés, la fonte de première fusion liquide est transportée dans des voitures torpédo jusqu'à l'atelier où elle sera traitée de différentes manières.  Au cours de ce voyage, la fonte brute et l'acier perdent une grande quantité de chaleur.  Pour éviter cette perte, les usines utilisent deux types de procédés.  L'un d'eux consiste à utiliser de la paille de riz que l'on jette à la surface du bain afin de former une couche qui continuera à brûler, produisant de l'énergie et, de ce fait, maintenant la température du métal liquide.  L'autre procédé, qui est de plus en plus utilisé, consiste à augmenter la température de la coulée qui sort du haut fourneau afin de compenser la perte d'énergie du métal liquide en mouvement.  La présente invention permet de réduire les coûts industriels et d'apporter une solution nouvelle au recyclage des déchets des usines, elle concerne un nouveau procédé qui permet de pallier les inconvénients des procédés utilisés à l'heure actuelle, qui est économiquement praticable et qui permet de contribuer à réduire la pollution environnementale.

Title: Nouvelles proteines hybrides issues de la nuclease staphylococcique et destinees a la production de peptides recombinants
Inventor: SU ZHENGDING
IPC: C12N15/62
Filed: 2003-08-07
Abstract: L'invention concerne la production de peptides sous la forme de fusions avec une protéine porteuse appropriée. Les protéines porteuses selon l'invention sont conçues à partir du domaine N-terminal de la nucléase de staphylococcus. Cette nouvelle protéine porteuse agit de manière à favoriser la surexpression de la fusion peptide-protéine sous la forme de corps d'inclusion, minimisant ainsi la protéolyse dans la cellule de peptides recherchés. La protéine hybride est aisément purifiée au moyen de procédures classiques ou de la chromatographie d'affinité par étiquette His quand une telle étiquette est introduite dans la protéine hybride. Le peptide cible est libéré de la protéine hybride purifiée au moyen d'une simple étape de clivage et il est séparé de la protéine porteuse libérée au moyen d'un processus de chromatographie HPLC à phase inversée ou par répétition du même procédé de purification par affinité. Le procédé selon l'invention présente un caractère avantageux, en plus des rendements élevés, en ce qu'il est utilisé aux fins de production de peptides étiquetés par voie isotopique et destinés à une caractérisation NMR de peptides bioactifs et leurs interactions avec des protéines cibles.

Abstract: EFFICIENT ENCODING/DECODING IN THE DECOMPOSITION AND RECOMPOSITION OF A         HIGH RESOLUTION IMAGE Abstract More efficient encoding/decoding in decomposing and decomposing a high resolution image is obtained by employing a unique pixel cluster arrangement. The pixel clusters of an image are classified as one of a plurality of classifications. A unique encoding/decoding technique is assigned to each classification. In one embodiment, a cluster including at least one high resolution pixel to be recomposed from a corresponding low resolution pixel which is a so-called exception to general prediction rules is classified as a first classification. A cluster including no pixels which are exceptions is classified as a second classification. Supplemental information is encoded/decoded for all pixels in a cluster classified as the first classification. Pixels in the cluster classified as the second classification are encoded/decoded according to the general prediction rules. (FIG. 1)

Abstract: SUSPENSION WITH STIFFENER ARM  ABSTRACT OF THE DISCLOSURE A air spring suspension system includes ground-engaging wheels mounted on an axle housing which is secured to trailing arms pivotally mounted at one end to the frame of the vehicle for vertical swinging movement relative thereto.  The other ends of the trailing arms are connected by a transverse beam which extends between them.  The beam is connected with the trailing arms by bushed articulating joints which permit the trailing arms to move with respect to each other.  A stiffener arm is mounted at one end to each trailing arm by a bushed connection, and rigidly secured at another end to the transverse beam near to where the transverse beam is connected to the trailing arm.  The bushed connection between the stiffener arm and the trailing arm provides limited articulation, and resists roll forces imparted to the suspension when the vehicle turns to provide increased stiffness at low rates of roll.
