Patent CA-2195197-A1 (CA)
Title: Corticotropin-releasing factor-binding-protein inhibitors and their use
Inventor: VALE WYLIE W JR
IPC: A61P25/28
Filed: 1995-07-14
Abstract: Levels of free corticotropin-releasing factor (CRF) in the brain are increased by administration to a patient of a ligand inhibitor of a CRF/CRF-binding protein complex. The ligand inhibitor binds to CRF-binding protein causing the release of CRF. The ligand inhibitor may be a peptide derived from CRF or a related protein or a non-peptide. Administration of the ligand inhibitor may provide improvement in learning and memory, resulting in decreased food intake or provide treatment for diseases associated with low levels of CRF in the brain, notably Alzheimer's disease. A method is also provided for screening compounds to select particularly effective CRF antagonists for in vivo administration to mammals.

Patent CA-2210397-A1 (CA)
Inventor: CHRISTENSEN KURT HESSELDAHL
IPC: B65G27/32
Filed: 1996-01-29
Abstract: Les circuits d'entraînement connus pour transporteurs vibrants commandent la puissance fournie au moyen d'un transformateur variable ou d'un système de régulation à commande de phase. Les transporteurs sont réglés mécaniquement sur la fréquence du réseau électrique ou sur son double. Cela présente des inconvénients, par exemple le fait que le réglage mécanique doive être effectué régulièrement, le transporteur étant alors arrêté. Selon l'invention, on mesure en permanence le courant et la tension, et des relations élémentaires permettent de calculer la longueur de l'interstice sur la base de ces mesures. Le résultat est utilisé dans une boucle de commande qui maintient l'alimentation sinusoïdale en électricité à la fréquence de résonance mécanique considérée, qu'il n'est pas nécessaire, par conséquent, de régler périodiquement.

Abstract: A method of holographic recording in a photorefractive medium wherein stored holograms may be retrieved with maximum signal to noise ratio (SNR) is disclosed. A plurality of servo blocks containing position feedback information is recorded in the crystal (200) and made non-erasable by heating the crystal (300). The servo blocks are recorded at specific increments, either angular or frequency, depending whether wavelength or angular multiplexing is applied, and each servo block is defined by one of five patterns. Data pages are then recorded at positions or wavelengths enabling each data page to be subsequently reconstructed with servo patterns which provide position feedback information. The method of recording data pages and servo blocks is consistent with conventional practices. In addition, the recording system also includes components (e.g. voice coil motor) which respond to position feedback information and adjust the angular position of the reference angle of a reference beam to maximize SNR by reducing crosstalk, thereby improving storage capacity.

Abstract: L'invention concerne un système et un procédé pour ajuster automatiquement un seuil de détection dans un défibrillateur qui surveille l'activité électrique du coeur et, en réponse, envoie des impulsions électriques appropriées. Un amplificateur amplifie l'activité électrique. Un circuit de détection détecte les dépolarisations dans l'activité électrique amplifiée. Il fournit ensuite un signal de détection d'un événement cardiaque correspondant à une dépolarisation, quand l'activité électrique amplifiée dépasse un seuil de détection variable. Un circuit numérique d'ajustement du seuil de détection réagit rapidement aux amplitudes détectées de l'activité électrique, pour placer le seuil de détection variable à un niveau proportionnel à la valeur de pic de l'amplitude de l'activité électrique amplifiée. Ensuite, il diminue le seuil de détection variable depuis ce niveau par des étapes discrètes, jusqu'à ce que le seuil de détection variable arrive à une valeur de seuil basse. Les étapes discrètes sont groupées en groupes d'étapes. Chaque groupe d'étapes diminue le seuil de détection variable d'un pourcentage défini.

Title: Catheter for peritoneal dialysis
Inventor: NILSSON CHRISTER
IPC: A61M25/14
Filed: 1996-10-09
Abstract: Catheter, particularly intended for peritoneal dialysis, comprising a proximal end arranged for connection with a supply and removal arrangement for peritoneal dialysis liquid, and a distal end which is intended to be placed into the peritoneal cavity and provided with a plurality of holes (21, 22) as well as a tip opening (17). The tip is provided with an insert (18) consisting of a restriction (19) and a diffusor (20). The flow which passes out through the tip opening is thereby reduced to 20 % - 25 % of the total flow, while the outflow speed is kept low due to the diffusor. A restriction (26) may be positioned along the portion of the catheter provided with holes at about twothirds the distance of the vented catheter region measured from the tip opening. The holes in the sidewall of the catheter may comprise different dimensions so that the holes (21) closest to the tip have a small diameter, while the holes (22) near the restriction (26) comprise a larger crosssectional area. The holes (21) which are closest to the restriction seen from the tip again have the smaller cross-sectional area, followed by holes (22) with larger cross-sectional area. In this way, approximately the same outflow speed is obtained through the different holes as well as through the tip opening.
