Abstract: Un système de communication équilibre le trafic de messages entre et au sein des groupes de voies de retour, de sorte que l'utilisateur ne commande par la fréquence d'émission spécifique utilisée. Les fréquences de liaison montante et les largeurs de bande pour les voies de retour sont établies par le système dans un message de commande de voie de retour, contenu dans le signal diffusé, de manière que la charge du système et du groupe de voies de retour soit pris en compte ainsi que l'arriéré de messages utilisateur. Une émission initiale par un utilisateur éloigné peut être effectuée au moyen d'un signal impulsif du type ALOHA envoyant un arriéré de message à la station de commande, sur une fréquence déterminée par un processus de sélection de fréquence en fonction de la charge, et pondéré de manière aléatoire. Le système, et non pas les utilisateurs individuels, déterminent les attributions de fréquence et de voie. Pour les arriérés importants ou les utilisateurs prioritaires, une largeur de bande périodique est prévue. Un procédé d'équilibrage des charges parmi et entre les groupes de voies de retour du système de communication, consiste à demander à une station de commande la largeur de bande de voies de retour dans un message sol-air d'un utilisateur éloigné. Le message sol-air peut comprendre à la fois un indicateur d'arriéré et une demande d'attribution de largeur de bande fournis à un centre d'exploitation de réseau (NOC) pouvant être utilisé pour fixer la largeur de bande des voies de retour et la fréquence pour la liaison montante éloignée. Un message utilisateur est transmis sur la fréquence de voie de retour désignée, dans la largeur de bande attribuée en fonction de l'indicateur d'arriéré et d'une demande d'attribution de largeur de bande, de sorte que les charges de trafic soient équilibrées entre les groupes de fréquences de voies de retour, et au sein de chaque groupe de fréquences de voie de retour.

Title: Recovery of sulfur from h2s and concurrent production of h2 using short contact time cpox
Inventor: KELLER ALFRED
IPC: C01B17/04
Filed: 2000-07-26
Abstract: A method, apparatus and system for treating a stream containing H2S are disclosed. A preferred method comprises mixing the stream containing H2S with a light hydrocarbon stream and an oxygen containing stream to form a feed stream, contacting the feed stream with a catalyst while simultaneously raising the temperature of the stream sufficiently to allow partial oxidation of the H2S  and partial oxidation of the light hydrocarbon to produce a product stream containing elemental sulfur, H2O, CO and hydrogen, and cooling the product stream sufficiently to condense at least a portion of the elemental sulfur and produce a tail gas containing CO, H2, H2O and any residual elemental sulfur, and any incidental S2O, COS, and CS2 from the hydrocarbon stream or produced in the process. The CO in the tail gas is then reacted with water to produce CO2 and hydrogen. Any elemental sulfur, SO2, COS, and CS2 in the tail gas is preferably converted into H2S, and the resulting H2 and H2S-containing tail gas stream is then contacted with an alkanolamine absorber to remove the H2S, producing a hydrogen stream which may be compressed and further purified for use in a hydrogen consuming process.

Abstract: An animal experiment method is proposed, in which a live test animal is prepared, and at least one tube is intubated into a body of the test animal, wherein one end of the tube comes into contact with body fluid of the test animal, and the other end of the tube is exposed to outside of the test animal. And, a monitoring system is connected to the exposed end of the tube, so as to monitor instant physiological conditions of the test animal in a limited space. Since the test animal stay alive and conscious during entire experiment, no anesthetic is necessarily applied to the test animals, and no undesirable interference caused by anesthetics with animal physiological mechanisms is generated. Therefore, experimental results can truly reflect real physiological and pharmaceutical conditions of the test animals, thereby making experimental data more reliable and significant for use as clinical reference.

Title: Support d'enregistrement magnetique et procede de fabrication dudit support
Inventor: WELLER DIETER KLAUS
IPC: H01F10/30
Filed: 2001-06-01
Abstract: On conçoit un disque d'enregistrement magnétique en zones magnétiques et non magnétiques discrètes, lesdites zones servant de bits utiles de données d'enregistrement magnétique. La couche d'enregistrement magnétique (20) comporte deux films ferromagnétiques (22, 24) séparés par un film de séparation non ferromagnétique (26). On sélectionne l'épaisseur et la composition de la matière du film de séparation (26), de telle manière que les premier et second films ferromagnétiques (22, 24) sont couplés de manière anti-ferromagnétique à travers le film de séparation (26). Une fois cette couche d'enregistrement magnétique (20) formée sur le substrat du disque (11), on l'irradie d'ions (62) par le biais d'un masque à motifs (60). Les ions rompent le film de séparation (62), ce qui détruit le couplage anti-ferromagnétique entre les deux films ferromagnétiques (22, 24). Par conséquent, dans les zones (55) de la couche d'enregistrement magnétique (20) que l'on irradie d'ions, les premier et second films ferromagnétiques (22, 24) sont essentiellement couplés sur le plan ferromagnétique, de telle manière que les moments magnétiques des films ferromagnétiques (22, 24) sont parallèles et produisent un moment magnétique qui est égal à la somme des moments des deux films (22, 24). Dans les zones non irradiées (52, 54) de la couche d'enregistrement magnétique (20), les premier et second films ferromagnétiques (22, 24) restent couplés sur le plan anti-férromagnétique, de telle manière que leurs moments magnétiques sont orientés dans un sens antiparallèle. On sélectionne la composition et l'épaisseur des premier et second films ferromagnétiques (22, 24), de telle manière que pratiquement aucun champ magnétique n'est décelable à une distance prédéterminée au-dessus de la couche d'enregistrement magnétique (20) correspondant à la hauteur à laquelle la tête d'enregistrement magnétique serait située.

These signals are constantly displayed for the operators who manually control the machine (20), archived for record purposed and/or extended to feedback loops of control means for automating control of the tensions during operation of the machine (20). Better quality control and avoidance of corkscrew, wave or sunken strand phenomena are aimed at.

Abstract: L'invention concerne une méthode permettant de réaliser une recombinaison homologue entre un segment d'acide nucléique natif dans une cellule et un segment d'acide nucléique donneur introduit dans le cellule. Cette méthode consiste à a) introduire dans une cellule un système de distribution d'acides nucléiques contenant (i) un troisième brin d'oligonucléotide doté d'une séquence de base pouvant former une triple hélice au niveau d'une région de liaison sur au moins un des brins d'un segment d'acide nucléique natif, (ii) un acide nucléique donneur doté d'une séquence d'acide nucléique suffisamment homologue au segment d'acide nucléique natif, de telle manière que la séquence donatrice peut subir une recombinaison homologue avec la séquence native au niveau de la région cible, (iii) un segment adaptateur doté d'une séquence d'oligonucléotide pouvant lier au moins une portion dudit acide nucléique donneur par un appariement de base de Watson-Crick, ledit segment adaptateur étant lié audit troisième brin d'oligonucléotide. Ladite méthode consiste aussi à b) permettre à l'oligonucléotide de se lier au segment d'acide nucléique natif pour former un acide nucléique à triple hélice, ce qui inclut donc une recombinaison homologue au niveau de la région cible du segment d'acide nucléique natif, et c) enfin permettre à une recombinaison homologue de se produire entre les segments d'acide nucléique donneur et natif. On peut notamment mettre en oeuvre cette méthode afin d'effectuer une altération génétique ou une réparation de mutation au niveau d'un site de séquence spécifique sur un ADN double brin.
