Abstract: A frequency mixer circuit comprises a first differential circuit (12) composed of first and second transistors having common-connected emitters, and a second differential circuit (14) composed of third and fourth transistors having common-connected emitters. A collector of the first transistor is connected to a collector of the third transistor and also connected through a first resistor to V CC . A collector of the second transistor is connected to a collector of the fourth transistor and also connected through a second resistor to V CC . A base of the first transistor is connected to a base of the fourth transistor, and a base of the second transistor is connected to a base of the third transistor. An emitter-grounded, fifth transistor is connected at its collector to the common-connected emitters of the first and second transistors, so as to constitute a current source for driving the first differential circuit. An emitter-grounded, sixth transistor is connected at its collector to the common-connected emitters of the third and fourth transistors, so as to constitute a current source for driving the second differential circuit. The base of the first to fourth transistors are biased with a first bias voltage, and a first high frequency signal is applied in the form of an unbalanced signal to the base of the first and fourth transistors. The base of the fifth and sixth transistors are biased with a second bias voltage, and a second high frequency signal is applied in the form of an unbalanced signal to the base of the fifth transistor.

Abstract: A pneumatic tyre and a method of making the same are disclosed, wherein the tyre is made by vulcanising a green tyre in a split mould. The mould has circumferentially extending split lines at a position corresponding to the tyre buttress region (11). The inner surface of the mould is provided with protrusions (12) immediately radially outside the split lines and a rib (13) immediately radially inside the split lines, so that the finished vulcanised tyre has depressions and grooves corresponding to the protrusions and rib, respectively. During mould closure in the manufacture of the tyre the raw tyre rubber does not get between the split faces of the mould as the protrusions and ribs (12,13) resist this, and the occurrence of burrs along the mould-split lines can be completely prevented.

Abstract: Système informatique comprenant un ou plusieurs écrans, tels qu'un écran cathodique (CRT) ou un afficheur à cristaux liquides (LCD) permettant un affichage visible pour l'utilisateur du système. Le système informatique comprend un contrôleur d'affichage vidéo (VDC) à générateur graphique. Celui-ci reçoit les données-images, telles que du texte ou des graphismes générés par un processeur (UC) ou ramenés par l'UC depuis un autre équipement (tel qu'un CD-ROM) du système informatique, et fournit des signaux commandant l'afficheur cathodique ou l'afficheur à cristaux liquides ou les deux. Le contrôleur d'affichage vidéo comprend un séquenceur et contrôleur (SEQC) destiné à une mémoire à accès direct dynamique (DRAM) en interface avec le VDC. Le SEQC arbitre les requêtes provenant des divers équipements du système informatique pour l'accès àla mémoire DRAM et organise cet accès en fonction d'un schéma de priorités multi-niveaux. Ce système assure aux divers équipements du système informatique un accès plus efficace à la mémoire DRAM, ainsi qu'une meilleure utilisation de cette dernière, et réduit le temps qui leur est parfois nécessaire pour accéder à la mémoire DRAM.

Title: System and method for producing drug-loaded microparticles
Inventor: BOMBERGER DAVID C
IPC: A61K39/00
Filed: 1996-06-06
Abstract: Method and system of producing microparticles loaded with biologically active drugs, including proteins such as ICAM-1, for controlled release of the drugs in a nasal passageway. The method includes introducing a drug/polymer feed solution and an emulsifier into a first mixing chamber to create an emulsion, then mixing a cross-linking agent together with the emulsion under controlled conditions to create microparticles loaded with the drug. The system includes a first mixing chamber, in which the emulsion is created, having a first port for introducing the drug/polymer solution, and a second port angled substantially perpendicular to the first port for introducing the emulsifier. A second mixing chamber adjacent to the first mixing chamber receives the emulsion and either contains a cross-linking agent or receives a stream of a cross-linking agent to solidify the microparticles. The formed microparticles are filtered and deaggregated to form individual microparticles that then may be formulated for nasal passageway delivery.

Abstract: The present invention relates to a method for making joints (10) between pipes. A first pipe part (1) to be connected is made of plastic material and it has an original inner diameter (D1), which is smaller than the outer diameter (D2) of a second pipe part (2) to be connected. The end section (11) of the first pipe part is expanded so that its inner diameter becomes larger than the outer diameter of the second pipe part; the first and second pipe parts can then be arranged one within the other, and the memory of the plastic material is allowed to reset the dimensions of the first pipe part, which then presses against the second pipe part forming a shrink joint (10) between the pipe parts (1, 2). Both end sections (11) of the first pipe part are expanded, and support pieces (3a, 3b) maintaining the expanded inner diameters are placed within the pipe parts. After the first pipe part has been transported to the site of operation, the support piece is removed, the first and second pipe parts are placed one within the other, and the memory of the plastic material is allowed to reset the expanded section of the first pipe part in order to provide a shrink joint between the pipe parts.

Abstract: For acquiring and evaluating measured variables which are critical for safety, e.g. yaw rates (GR), as input variables of a motor vehicle control system, the measured variables are obtained by means of two mutually independent measuring channels (M1, M2) of which one measuring channel (M1) acquires the entire range to be measured whilst the other measuring channel (M2) is set at a partial range. In order to detect errors, the output variables of the measuring channels (M1, M2) are checked for conformance of the measured variables acquired by the measuring channels and/or for plausibility of the measurement results.

Abstract: L'invention concerne de nouveaux réactifs bifonctionnels de phosphitylation et leur application dans la préparation in situ de phosphoramidites de nucléosides protégés en position 5', ainsi que la synthèse d'oligonucléotides. Ces réactifs bifonctionnels de phosphitylation réagissent rapidement avec des nucléosides dans des conditions neutres ou faiblement basiques, sans étape supplémentaire d'activation. De plus, ces réactifs génèrent in situ, de façon chimiquement sélective, les phosphoramidites de nucléosides correspondants, sans qu'il soit nécessaire de purifier les phosphoramidites de nucléosides avant de les utiliser dans la synthèse d'oligonucléotides. Enfin, ces réactifs sont relativement stables et faciles à manipuler.

Les modes de transmission par salves assurent différentes combinaisons de modulation (de type QPSK et 16-QAM), de débits de symboles, de niveaux de codage FEC et de structure de trame et de préambule. Ledit appareil convient particulièrement aux transmissions montantes sur des réseaux hybrides de télévisions reliées par câbles coaxiaux à fibres optiques.
