Filed: 1995-10-19
Granted: 2010-02-16
Abstract: La présente invention concerne un procédé de prolongation de la conservation des plaquettes sanguines humaines à température réduite. Le procédé met en oeuvre un système inhibiteur permettant aux plaquettes sanguines de conserver leur forme discoïde et de conserver leur intégrité fonctionnelle pendant le stockage. Le procédé consiste à interrompre les fonctions normales des plaquettes pendant le stockage pour empêcher que les plaquettes ne s'activent et perdent leur forme. Avant d'utiliser les plaquettes en transfusion, un lavage élimine le système inhibiteur des plaquettes, ce qui leur fait reprendre leur niveau fonctionnel normal.

Abstract: Procédé et dispositif comprenant un moule qui définit une cavité (200) comportant une admission par laquelle une matière maléable en fusion est admise à l'intérieur de la cavité ou traverse celle-ci. Un dispositif de remplissage, permettant de préparer la matière maléable en fusion, est placé à distance du moule et expulse la matière en direction de la cavité ou d'un accumulateur relié à cette cavité. Un mécanisme assure la régulation de la température de la matière dans le dispositif d'alimentation, l'accumulateur et le moule, ainsi que la température d'au moins une unité d'injection de gaz (1000, 2000) qui contrôle le gaz, avant, pendant et après son injection dans la cavité et/ou dans les conduites de gaz situées à l'intérieur ou autour de la cavité. Un système de régulation en circuit fermé permet d'ajuster aisément le flux de gaz et de contrôler la pression moyenne du gaz injecté en fonction d'un signal d'état programmé. L'unité d'injection de gaz comporte des soupapes de sécurité (10, 20) et des réservoirs à gaz. Elle comporte également un dispositif de purge/mise à l'air libre (2020) qui permet de réaliser le vide à l'intérieur de la cavité et/ou des conduites de gaz et/ou d'induire un différentiel de pression générateur d'un flux de gaz sous pression.

Title: Memory exceed notification for wireless network communication device
Inventor: LAWRENCE CHRISTOPHER GREGORY
IPC: G08B5/22
Filed: 1997-06-09
Granted: 2007-03-27
Abstract: A wireless communication device comprises a memory exceed indicator. The wireless communication device receives a message from a network. Upon receipt of the message, the device determines whether there is sufficient memory to store the message. If there is insufficient memory, the device activates a memory exceed indicator which indicates that a message is being stored in the network and that the memory of the wireless communication device contains insufficient memory to receive and store that message. If one or more messages are deleted from the memory of the device in order to make mom for new messages, then a new message received from the network is stored in the memory of the device and the memory exceed indicator is deactivated.
Patent CA-2233281-C (CA)
Title: Fire suppression system
Inventor: SHIPLEY WILLIAM
IPC: A62C35/02
Filed: 1998-03-26
Granted: 2007-05-29
Abstract: The present invention relates to a fire suppression system and method in which an extinguishing agent is automatically discharged from a limited source of supply of the wet chemical extinguishing agent for rapid extinguishment of the fire, followed by water application to the locus of the fire from an unlimited source of supply of water. The subsequent automatic application of water provides rapid cooling of the hot burning material below its reflash temperature. The present hybrid system exploits the best fire suppression properties of both agents against fires i.e. the wet chemical extinguishing agent provides rapid flame extinguishment and water provides rapid cooling following extinguishment. The present hybrid system is significantly more robust (fire test variables are less critical to its fire suppression performance) than current water or wet chemical agent systems.
Patent CA-2235744-C (CA)
Title: Apparatus for buffering the dc voltage at the output of a power supply
Inventor: GEHRE HANS-JOACHIM
IPC: H02J9/06
Filed: 1996-10-23
Granted: 2005-05-24
Abstract: The buffer apparatus contains at least one buffer battery (BATT), in particular a rechargeable battery which can be charged via the power supply (SV), and a control unit (CU). The latter connects the buffer battery when the actual value of the DC voltage (Ua) is less than a predetermined minimum value (Uamin), generates a predetermined buffer time period (tm) and disconnects the buffer battery again, cyclically, after this time period has elapsed. The apparatus according to the invention has the advantage that the return of the output DC voltage of the power supply can be identified effectively without major complexity. The loads continue to be supplied both in the event of a failure of the supplying input voltage and in the event of a failure of the rower supply, since the output DC voltage, which is essential for the loads, of the power supply is monitored. The apparatus can be connected additively downstream of a power supply, without any intervention in its design being necessary.      The apparatus has the further advantage that it automatically connects the battery as a back-up, even in the event of drops in the output DC voltage caused by short-circuits, as soon as the load voltage falls below the minimum value. The invention thus enables a virtually continuous transfer and back-up of the output DC voltage in a multiplicity of fault situations.
