Abstract: A method and system for identifying personal possessions belonging to a number of owners includes a set of bar code labels, each bearing a predefined identifying insignia, each insignia corresponding to a unique owner.  Labels are affixed to the personal possessions. A set of owner identifiers is stored at a first location wherein each owner identifier corresponds to a unique owner. For each owner identifier stored, a set of insignia data records is also stored. Each insignia data record corresponds to one of the set of labels. At a second location, remote from the first, identifying data is input corresponding to the identifying insignia on one of the labels by scanning the bar code. The identifying date is received at the second location and transmitted to the first location. The identifying data is compared with the insignia data stored in a secure manner at the first location. Where the identifying data matches one of the insignia data records, the owner identifier is retrieved and displayed.

Patent CA-2177169-A1 (CA)
Inventor: BAUMANN THOMAS
IPC: H01L39/16
Filed: 1995-09-25
Abstract: In order to limit overload currents in electric lines, caused by a short circuit for instance, the invention calls for a current limiter to be inserted in the electric line to limit the overload current to a given multiple of the nominal current.  The simple, compactly designed current limiter has, disposed on each side of a disc-shaped insulator (1), a composite conductor made up of a high-temperature superconductor (3, 3') and a normal conductor  (4, 4') connected flat against each other to give good electrical contact.  Between the composite conductors and the insulator (1) is a chemically insulating buffer layer (2) made of 2-µm-thick silver.  Either the superconductor  side or the normal-conductor side of the superconductor makes flat contact with the insulator (1). The electrical resistance of the shunt (4, 4) should not be greater than that of the superconductor (3, 3') connected to it.  Each composite conductor is meander-shaped in design and electrically connected so that the current in adjacent strips of the composite conductor flows in opposite directions.

Title: Method for culturing mammalian cells and insect cells in a medium containing fish serum
Inventor: SAWYER EVELYN S
IPC: C12N5/00
Filed: 1994-12-09
Abstract: A method for culturing mammalian cells using fish serum. The method uses serum extracted from the blood of fishes to culture mammalian cells for various purposes. The technique has the key advantages of 1) freedom from mammalian infectious agents that could contaminate cell lines or endanger researchers or recipients of therapeutants derived from mammalian cell culture; 2) consistent and reproducible serum content and quality; 3) low cross-reactivity; and 4) provision of the appropriate serum nutrients to maintain the growth of mammalian cells. Fish serum is used together with designated defined media to allow mammalian cells to grow and populations of these cells to be maintained. Blood serum is derived from captive stocks of fish raised under controlled conditions such that the diet, habitat genetics, life history, and reproductive status of the fish remains substantially consistent and reproducible.
Patent CA-2184397-A1 (CA)
Title: Flexible Press
Inventor: FRANK ROBERT G
IPC: B21D22/14
Filed: 1996-08-28
Abstract: A flexible shaping ring for shaping heat softened glass sheets lifts a heat softened glass sheet and presses it against the shaping surface of an upper mold. As the shaping ring presses the marginal edge portion of the sheet against the upper mold, its shaping surface deforms to generally conform to a corresponding portion of the upper mold. A press ring subsequently contacts the shaping ring and presses it against the upper mold to further shape the marginal edge portion of the glass sheet and ensure the marginal edge completely conforms to the shape of the upper mold.

IPC: C12N15/13
Filed: 1995-06-16
Abstract: The variable chains of two human monoclonal antibodies (HMAbs) of the IgM  isotype are characterized by elucidation of cDNAs encoding those chains. The HMAbs are specific against cell cycle independent, glioma-associated antigen, and the antibodies do not recognize cultured normal human astrocytes.  Immunoconjugates based on the sequences identified should target both proliferating and non-proliferating glioma cells in vivo, thus providing a valuable adjunctive therapy in the treatment of these tumors.
Patent CA-2193505-A1 (CA)
Title: Capacitor polarity-based var correction controller for resonant line conditions and large amplitude line harmonics
Inventor: KEMERER RAY S
IPC: H02J3/18
Filed: 1995-06-06
Abstract: The invention is a static VAR compensator (SVC)(18) which provides optimized power factor correction in the presence of resonant line conditions and large amplitude harmonics. A gate drive signal is applied to the solid state devices (21) of the SVC (18) during only a minor fraction of the fundamental cycle to prevent damage to the solid state devices (21 ) and the capacitors (20) of the SVC (18), otherwise caused by resonant line conditions or large amplitude harmonics. This relatively short gate drive signal, in the presence of large amplitude harmonics, will force the solid state electronic components to turn-off prematurely. As a result, the capacitors (20) of the SVC (18) provide incomplete reactive power compensation. Feedback from a capacitor polarity circuit (31) is used to determine switched capacitor status at a specific instant in each cycle. A VAR correction controller (24), responsive to the feedback, executes a control scheme to account for incomplete reactive power compensation.

Title: Method for transferring and displaying data pages on a data network
Inventor: DOUGLIS FREDERICK
IPC: H04L29/06
Filed: 1997-09-30
Abstract: The apparent speed of a connection between a browser at a user station and a proxy or gateway on a network such as the Internet is increased by providing a local proxy at the user station which interacts with a remote proxy.  While the remote proxy is retrieving a newly requested World Wide Web page, for example, from the appropriate content provider, it may also be sending to the local proxy a stale cached version of that page.  When the new version of the page is finally retrieved, the remote proxy determines the differences between the new version and the stale version, and, assuming the differences do not exceed the new page in size, sends the differences to the local proxy which then reconstructs the new page from the differences and the stale version.  The local proxy delivers the new page to the browser, which need not even be aware that a local proxy exists; it is aware only that it received the page it requested.  Because computational speed and power are frequently higher and cheaper than transmission speed, the apparent speed of the connection between the user station and the network has been increased at modest cost.
