Abstract: Le dispositif de perfusion rapide est un système de pompage mécanique pour l'apport rapide d'un volume de fluide filtré, sans bulle, chauffé à un patient souffrant d'hypovolémie aiguee. Le principe de fonctionnement permet de surmonter la résistance mécanique. L'écoulement des fluides est entièrement régulé par la résistance rencontrée au niveau de l'orifice du tube le plus petit le long du chemin de perfusion. Les composants du dispositif de perfusion rapide, assemblés sous la forme d'un système, assurent la perfusion rapide d'un volume de fluide filtré, sans bulle et chaud. Le mot volume est utilisé pour décrire le fluide apporté par le dispositif. Le dispositif de perfusion rapide (RID) se compose de deux systèmes, à savoir un équipement permanent durable et une unité jetable s'utilisant une seule fois. L'équipement durable consiste en une pompe à rouleau (22), ses commandes (12), un élément de chauffage monté à demeure (38) et ses commandes (39), et une console de montage (37) pour fixer l'élément de chauffage au corps (21) de la pompe à rouleau. L'unité jetable (50) est constituée en plastique moulé coulé en deux moitiés. Tous les sous-composants de l'unité jetable (50) sont montés au stade de la fabrication et avant que les deux moitiés soient jointes, collées et scellées pour assurer l'intégrité du liquide.

Abstract: Procédé servant à l'enregistrement de spectres de résonance magnétique sur des échantillons comportant au moins trois groupes de spins. Un premier groupe est couplé avec un deuxième groupe, tandis qu'un troisième groupe est sans couplage avec le deuxième, mais présente une position spectrale, p. ex. un décalage par suite de liaison chimique, qui concorde pour l'essentiel avec la position du premier groupe, et seulement de ce dernier. Pour représenter le seul signal originaire du premier groupe, il faut supprimer le signal du troisième groupe. De manière connue en soi, on soumet l'échantillon à une séquence de trois impulsions de radiations HF (10, 13, 17). On règle la deuxième impulsion (13) de telle sorte que l'état de magnétisation des spins des premier et deuxième groupes, par transfert de cohérence, soit transmis dans un état de cohérence de deux quanta. Ensuite, l'échantillon est soumis à une première impulsion de champ magnétique à gradient (15), de surface prédéterminée (epsilon2), et de nature à déphaser l'état de cohérence des deux quanta. La troisième impulsion HF est réglée de telle sorte que la cohérence à deux quanta soit retransmise par transfert de cohérence à l'état de cohérence à un quantum, état soumis finalement à une deuxième impulsion de champ magnétique à gradient (19), de nature à remettre en phase les spins du premier groupe (A), la surface de cette deuxième impulsion étant n fois celle de la première impulsion de champ magnétique à gradient (15).

Abstract: A method of controlling the operation of a solenoid, particularly for operating the fuel delivery valve of a fuel injector of an internal combustion engine. The method comprises controlling the rate of rise of the current in the solenoid (11) winding at a predetermined rate during at least the period between initiation of the current supply (10) and the commencement of movement of the solenoid armature. The said predetermined rate of rise of the current being preferably linear and being independent of the maximum rate attainable at the nominal voltage of the electrical source supplying the current. The rate of rise of the current is monitored (13) and the supply voltage is cyclically varied in response to said monitoring to maintain the predetermined rate of rise of the current. Also the cyclic variations of the current is monitored (22) to detect when the frequency of said cycles substantially change indicating the completion of the full extent of the movement of the solenoid (11) armature.

Abstract: 5 n7 The transformer comprises an annular core (1) of a soft-magnetic material on which there are provided a first winding and a second winding. The second winding comprises n turns more than the first winding. The first winding consistsd of a first conductor (3) and a second conductor (5), the second winding consisting of a third conductor (7). The three conductors (3, 5, 7) are twisted over a part of their length so as to form a cable (9) wherefrom a common winding is formed which includes at least a part of the second winding and substantially the entire first winding. Near one end of the common winding there are provided n additional turns of the first conductor (3) and near its other end there are provided n additional turns of the second conductor (5). The corresponding end portions of the first and second conductors (3, 5) are electrically interconnected in order to form terminals (13, 19) of the first winding, and the end portions of the third conductor (7) form terminals (11, 15) of the second winding. Because the n additional turns of the second winding are situated substantially symmetrically with respect to the first winding, the leakage inductance is comparatively low.
