Patent CA-2165183-A1 (CA)
Title: Alternateur hybride avec regulation de la tension
Inventor: SYVERSON CHARLES D
IPC: B60L50/15
Filed: 1994-06-09
Abstract: Alternateur hybride qui comporte un stator (10) et un rotor (20), le rotor (20) ayant des parties champ bobiné (24) et aimant permanent (38) séparées longitudinalement. Un circuit d'excitation du rotor applique une polarité avant sur la partie champ bobiné (24) du rotor pour augmenter le niveau de sortie dans un mode de tension additionnelle à des vitesses de rotation basses et une polarité inverse pour diminuer le niveau de sortie à des vitesses de rotation élevées dans un mode d'opposition pour maintenir une tension de sortie constante. D'autres modes de réalisation combinent une conception concentrant le flux magnétique pour un fonctionnement efficace à vitesse faible avec une structure intégrale pour le fonctionnement à vitesse élevée. Une tension de sortie double est obtenue soit grâce à deux bobinages de stator, soit grâce à un circuit de conversion de tension. Une tension de sortie unique est obtenue en utilisant seulement un bobinage de stator. Un régulateur de tension à trois états permet la régulation de la tension sans induire des courants inverses sur le bus de puissance dans des conditions de batterie faiblement chargée ou d'absence de batterie. Ledit régulateur possède un enclenchement automatique de manière à être allumé et éteint sans risque.

Title: Process and apparatus for controlling reaction temperatures
Inventor: GIROD CHRISTINE JEANNINE BERNA
IPC: C07C5/333
Filed: 1994-07-02
Abstract: A reactor arrangement and process for indirectly contacting a reactant stream (A) with a heat exchange stream (B) uses an arrangement of corrugated heat ex-change plates (10) to control temperature conditions by varying the number and/or the arrangements of the corrugations  (13) along the plates (10). The reactor arrange-ment and process of this invention may be used to operate a reactor under isother-mal or other controlled temperature con-ditions.  The variation in corrugation ar-rangements within a single heat exchange section is highly useful in maintaining a desired temperature profile in an arrange-ment having a cross-flow of heat exchange medium relative to reactants.  The corruga-tions arrangements eliminates or minimizes the typical step-wise approach to isother-mal  conditions.
