Patent CA-2065857-A1 (CA)
Inventor: HIETALA ALEXANDER W
IPC: H03L7/183
Filed: 1991-08-16
Abstract: Un synthétiseur à accumulateurs fractionnel-N déclenché ayant une erreur résiduelle réduite destiné à des émetteurs-récepteurs radio-numériques est divulgué. Le diviseur du dispositif diviseur de fréquence (103) du synthétiseur est modifié dans le temps par la somme des séquences numérique des sorties de report des 'accumulateurs, ce qui résulte en des accroissements de fréquence égales à une fraction de la fréquence de référence. Les accumulateurs (615, 617) sont déclenchés de façon qu'à l'arrivée de l'impulsion d'horloge, les données soient transférées dans chaque accumulateur successivement à chaque impulsion d'horloge, de sorte que le retard dans le système est égal à celui d'un seul accumulateur.  La sortie déclenchée de l'accumulateur du poids de second rang (619) est soustraite de la sortie déclenchée de l'accumulateur du poids le plus fort (621) et différenciée avant d'être appliquée au filtre à boucle (109).

Filed: 1992-04-15
Abstract: METHOD AND APPARATUS FOR PERFORMING MAPPING-TYPE     ANALYSIS INCLUDING USE OF LIMITED ELECTRODE SETS                  Abstract of the Disclosure A system (103 is disclosed that includes a monitor (16) for use in performing 12-lead electrocardiographic (ECG) and body surface mapping (BSM) analyses on a patient (12) with a single ten-electrode cable set (14). The monitor receives nine leads of data from the electrode cable set and initially preprocesses it to simplify further analysis. Then the data is transformed to produce a spatial distributionrelative to the patient's chest, representative of the data that would be collectible with a 192-electrode set. Feature extraction techniques are also described for use in evaluating transformed, as well as conventional, BSM data with respect to clinically evaluated populations. In that regard, features of interest are extracted from the data and statistically analyzed to detect select cardiac conditions.

Disturbances of cerebral and peripheral blood flow are likewise influenced beneficially.  Furthermore, compounds I are able to influence smooth-muscle organs such as uterus, bronchi, intestines and biliary system, the urinary tract (ureter, bladder and urethra) in the sense of spasmolysis.  They are therefore also suitable for the treatment of diseases associated with spasms of these organs, for example for the treatment of premature labor in pregnancy, of ureteral or biliary colic, of obstructive airway diseases such as asthma, of disturbances of intestinal motility such as, for example, of irritable colon or of bladder incontinence. Additionally, compounds of formula I can serve as anti-convulsants in the treatment of epilepsy and as hair growth inducers in the treatment of baldness.

Abstract: ABSTRACT A process for the preparation of isophorone nitrile utilizing solutions of lithium hydroxide or lithium cyanide, solid LiOH or solid LiOH?H2O as a catalyst. The reaction is carried out under precisely controlled temperature conditions and cyanide feed rate profiles to maintain a reasonably constant concentration of non-reacted cyanide, thereby minimizing the formation of undesirable diisophorone, its nitrile derivative(s) and HCN polymers. A polyacidic acid can be used to acidify the batch, followed by filtration to remove the precipitated lithium salt of the acid, and vacuum distillation to remove liberated HCN and excess isophorone. The resulting isophorone nitrile is obtained in high yield and with low impurity content.
