Patent CA-2071324-C (CA)
Title: Device for guiding a transversely stable web
Inventor: NIEMANN HEINRICH
IPC: B65H23/038
Filed: 1992-06-16
Granted: 1998-05-19
Abstract: For guiding webs of paper or cardboard, a guide cylinder extending across half of the web grips onto the surface of the web and achieves moving corrections on the webs by rotation or swinging.  The long, linear support zone of the guide cylinder causes a high mechanical stress, whereby the guide cylinder exerts almost no corrective effect in its center zone.  By dividing the guide cylinder into at least two spaced-apart, parallel guide rolls having their axes disposed perpendicular to the running direction of the material web, a suitable larger effective area is obtained for correction of the direction of movement.

Abstract: A hermetically sealed optical fiber cable (20) includes a core (21) comprising a plurality of optical fiber ribbons (22,22) disposed within a core tube (30) comprised of a high temperature resistant polymeric material. The core tube is disposed within a hermetic sealing member (40) which comprises a metal of low electrochemical activity having a sealed seam. An outer jacket (50) is disposed about the hermetic scaling member. The core may be filled with a waterblocking filling material (35). The material of the core tube undergoes only limited degradation because of the limited amount of oxygen and/or moisture trapped in the hermetically sealed cable. The filling material and/or other materials of the cable scavenge moisture and oxygen which travel longitudinally of the cable and reach portions of the cable subjected to a high temperature because of a leak in an adjacent steam line. The filling material and/or other materials are such that they cooperate with polymeric materials of the cable to prevent oxygen and humidity from degrading coating material of the optical fiber. Further, the filling material and the core tube are such that degradation of the core tube in the hermetically sealed cable is avoided.

Abstract: La présente invention concerne un groupe de composés qui sont des dérivés de la xanthine et qui agissent de façon sélective au niveau des récepteurs A1 de l'adénosine. Les antagonistes de l'adénosine agissant au niveau du récepteur A1 dépolarisent les neurones post-synaptiques et stimulent au niveau pré-synaptique la libération d'un certain nombre de neurotransmetteurs, dont l'acétylcholine, le glutamate, la sérotonine et la norépinéphrine. Cette action pourrait être utile pour traiter les déficits cognitifs tels que ceux liés à la maladie d'Alzheimer, car ces transmetteurs ont été associés à l'apprentissage et à la mémoire et leur nombre est réduit dans la maladie d'Alzheimer. Certains des composés anti-A1 décrits dans la présente invention ont stimulé l'activité des neurones de l'hippocampe dans un modèle d'apprentissage in vitro par potentialisation à long terme et inhibé un déficit en scopolamine dans un modèle d'apprentissage in vivo utilisant un labyrinthe aquatique. Ces composés pourraient donc avoir des effets bénéfiques sur la cognition.

Title: Biometrically secured control system for preventing the unauthorized use of a vehicle
Inventor: BORZA STEPHEN J
IPC: G07C9/00
Filed: 1995-08-16
Granted: 1999-07-20
Abstract: A method and system are provided for restricting the use of a vehicle such as anautomobile to a person or persons whose fingerprints match biometric data stored within a memory in the vehicle's control system. A user's digitized fingerprints are stored in a non-volatile permanent ROM in the BIOS of a microcontroller on in a ROM accessed by a microprocessor. The microprocessor's primary task is that of executing instructions related to the operation of the vehicle, such as regulating the fuel flow rate, and performing other such tasks. Before the microprocessor can execute its instructions related to its primary task it must complete and exit a conditional loop of instructions that relate to validating a user's "real-input" biometric data. Real scanned fingerprints must be compared with fingerprint(s) stored in ROM. If the result of the compare is a true, i.e. is a match, then the conditional loop is satisfied and the microprocessor can execute its instructions relating to operating the vehicle.

Abstract: A plasma-enhanced vacuum drying method is disclosed. It is advantageously applied in plasma sterilization processes in particular, and represents a significant improvement for general evacuation drying methods. Articles to be sterilized are placed in a sealed chamber and the chamber is evacuated. A plasma of residual gas species is generated in the chamber during an initial evacuation step. This promotes drying of the articles and advantageously allows a desired pressure to be attained more quickly than without the plasma. Sterilizing gas is injected into the chamber, and a second plasma is generated to activate the sterilizing gas plasma, thereby sterilizing the articles in the chamber.
