Patent CA-2415313-A1 (CA)
Title: Method and system for densifying cryogenic propellants
Inventor: HOOD CHARLES B
IPC: F25J1/02
Filed: 2001-07-12
Abstract: The present invention relates to methods and systems (100) for densifying liquids, specifically the densification of cryogenic propellants. A preferre d system of the present invention subcools and densifies liquid propellants by  utilizing a countercurrent gas or liquid flow. The countercurrent flow preferably utilizes a gas having a lower boiling point than the propellants.  A packed tower may then be used, at or above atmospheric pressure, to introduc e the countercurrent flow to the propellant. This methodology avoids the costs  and problems associated with subatmospheric operation. A preferred embodimen t is directed toward the densification of liquid oxygen and liquid hydrogen. Systems and methods of the present invention may also be used to densify oth er liquids in similar fashion.
Patent CA-2416664-A1 (CA)
Title: Zinc finger domain recognition code and uses thereof
Inventor: SERA TAKASHI
IPC: A61K48/00
Filed: 2001-07-19
Abstract: The present invention relates to DNA binding proteins comprising zinc finger  domains in which two histidine and two cysteine residues coordinate a centra l zinc ion. More particularly, the invention relates to the identification of a context-independent recognition code to design zinc finger domains. This cod e permits identification of an amino acid for positions -1, 2, 3 and 6 of the .alpha.-helical region of the zinc finger domain from four-base pair nucleotide target sequences. The invention includes zinc finger proteins (ZFPs) designed using this recognition code, nucleic acids encoding these UF Ps and methods of using such ZFPs to modulate gene expression, alter genome structure, inhibit viral replication and detect alterations (e.g., nucleotid e substitutions, deletions or insertions) in the binding sites for such proteins. In addition, the invention provides a rapid method of assembling a  ZFP with three or more zinc finger domains using three sets of 256 oligonucleotides, where each set is designed to target the 256 different 4- base pair targets and allow production of all possible 3-finger ZFPs (i.e., >>106) from a total of 768 oligonucleotides.
Patent CA-2419107-A1 (CA)
Inventor: LAFONTAINE DANIEL M
IPC: A61F2/958
Filed: 2001-06-18
Abstract: Devices and method for rcooling vessel walls to inhibit restenosis in conjunction with medical procedures such as coronary artery angioplasty.  Stenosed vessel walls can be cooled prior to angioplasty, after angioplasty, or both. The invention is believed to inhibit restenosis through cooling to a temperature near freezing, preferably without causing substantial vessel wall cell death. One catheter device includes a distal tube region having coolant delivery holes radially and longitudinally distributed along the distal region. In some devices, holes spray coolant directly onto the vessel walls, with the coolant absorbed into the blood stream. In other embodiments, a balloon or envelope in interposed between the coolant and the vessel walls and the coolant returned out of the catheter through a coolant return lumen. Some direct spray devices include an occlusion device to restrict blood flow past the region being cooled. Pressure, temperature, and ultrasonic probes are included in some cooling catheters. Pressure control valves are included in some devices to regulate balloon interior pressure within acceptable limits.  In applications using liquid carbon dioxide as coolant, the balloon interior pressure can be maintained above the triple point of carbon dioxide to inhibit dry ice formation. Some cooling catheters are coiled perfusion catheters supporting longer cooling periods by allowing perfusing blood flow simultaneously with vessel wall cooling. One coiled catheter is biased to assume a coiled shape when unconstrained and can be introduced into the body in a relatively straight shape, having a stiffening wire inserted through the coil strands.

Title: Multi-level security network system
Inventor: WILLIAMS TIMOTHY C
IPC: H04L12/22
Filed: 1999-07-21
Abstract: A network prevents unauthorized users from gaining access to confidential information. The network has various workstations and servers connected by a common medium and through a muter to the Internet. The network has two major components, a Network Security Center (NSC) and security network interface cards or devices. The NSC is an administrative workstation through which the network security officer manages the network as a whole as well as the individual security devices. The security devices are interposed between each of workstation, including the NSC, and the common medium and operate at a network layer (layer 3) of the protocol hierarchy. The network allows trusted users to access outside information, including the Internet, while stopping outside attackers at their point of entry. At the same time, the network limits an unauthorized insider to information defined in their particular security profile. The user may select which virtual network to access at any given time. The result is trusted access to multiple secure Virtual Private Networks (VPN), all from a single desktop machine.
Patent CA-2423147-A1 (CA)
Inventor: SLAMECKA ERNST
IPC: G01R31/333
Filed: 2003-03-24
Abstract: A method for testing high-voltage alternating-current power switches in a synthetic test circuit has the step of connecting a high-voltage oscillating circuit in parallel to a test switch B t in a time interval before the current zero of an interruptible high current, which is determined by a half-cycle duration (T h/2) of the oscillating current (i h) less the duration of equivalence (.increment.t se) of the sole flow of the oscillating current as sequential current in the test switch with a stress exerted upon the switch by the homogeneous current in a direct test circuit. The sequential-current flow duration of the equivalence results, at least approximately, from the comparison of the values of common physical stress parameters acting in the test switch during the test, on the one hand, in the synthetic test circuit and, on the other hand, in the direct test circuit.

Title: A cryopreservation bag assembly for mammalian cell lines
Inventor: MERED MOKHTAR
IPC: A61J1/00
Filed: 2002-05-09
Abstract: The invention is a novel cell freezing and storage bag assembly and method for using the assembly in the seed train expansion of mammalian cells. The bag is constructed principally of polytetrafluoroethylene fabric. The bag is designed to hold enough cells that a bioreactor can be inoculated directly. The bag is designed to be filled to a fraction of its maximum capacity so that the cell suspension has a very thin cross-section (less than about 10 millimeters). The bag design includes a transfer set that can be sterilely welded to the source of the mammalian cells. This sterile-weldable transfer set allows the bags to be filled quickly with minimal risk of contamination. In the method, once each bag is filled, it is sealed below the connection with the transfer set and the bag is cut "above" the new seal (on the same side of the seal as the transfer set). When a bioreactor is to be inoculated, the contents of the bag are drained via a sterile-weldable inoculation line. During freezing and storage, the inoculation line is protected from mechanical damage.

Title: Anti-submarining seat-belt assembly
Inventor: GO GIOK DJIEN
IPC: B60R22/03
Filed: 1998-11-10
Abstract: Seat belts of a transport system are provided with anti-submarindng seat-belt assemblies. A lap-belt portion of each assembly, restraining the lower part of the body of a belted passenger, is subdivided into two anti-submarining belt portions, which properly restrain the thighs when plug-in connecting at least one anti-submarining latch-plate to one of the anti-submarining buckle assemblies, all of which, equipped with energy absorbers, are arranged in a seat cushion. As a result, the energy-absorbing, anti-submarining seat-belt assembly substantially lowers great belt force in an accident, reduces the elongation of the seat belt and prevents submarining. A separately operated release button, when depressed, frees the passenger from the anti-submarining protection. Ease of use is ensured by one-click operation of a master release-button, which, when depressed, releases all latch-plates. Detachable anti-submarining latch plates, when not in use, are stored in a storage box. When needed they are attached to the lap-belt portion.
