Patent CA-2256322-A1 (CA)
Title: Biocompatible glue
Inventor: JOHANSSON-RUDEN GUNILLA
IPC: A61L24/00
Filed: 1997-05-30
Abstract: Use of one or more saccharides, for example one or more non-toxic mono-, di-, tri-, oligo- or polysaccharides, in the manufacture of a biocompatible glue for adhering a first structure to a surface of a second structure. The biocompatible glue can be adapted to act as a temporary glue. In this case the glue may be used to enable a medical structure to be transferred from a medical instrument onto the surface of a structure of a human or animal body, for example as in the transfer of a buffer material from the fork of a surgical stapler to a diseased lung after one or more rows of staples have been fired through the buffer material into the lung during lung volume reduction surgery for treating emphysema. The biocompatible glue can also to advantage be used to adhere or secure medical structures to a structure of a human or animal body direct, such as in the case of a patch being applied to the skin of a mammal.

Patent CA-2259518-A1 (CA)
Title: Annealing magnetic elements for stable mechanical properties
Inventor: GADONNIEX DENNIS MICHAEL
IPC: C22C45/02
Filed: 1997-06-25
Abstract: A control element for a magnetomechanical EAS marker is formed by annealing an amorphous metalloid (20) so as to be at least partially crystallized while remaining substantially flat. Preferably a two-stage process is applied to induce semi-hard magnetic characteristics in an amorphous metallic material (20) that is magnetically soft as cast. In a first stage (26), the material is annealed for at least one hour at a temperature below a crystallization temperature of the material. This produces a reduction in volume of the material. The second stage (30) is carried out at a temperature above the crystallization temperature for a time sufficient to crystallize the bulk of the material and give it semi-hard magnetic properties. The two-stage annealing process prevents deformation of the material which has resulted from conventional crystallization processes.

Title: Method and apparatus for performing authentication in communication systems
Inventor: BERENZWEIG ADAM L
IPC: H04L9/32
Filed: 1999-03-29
Abstract: A method and apparatus for permitting global roaming between two communication networks which utilize different authentication schemes. The authentication interoperability function (AIF) and method translate between the authentication schemes of each network, for example, a triplet-based network and a shared secret data (SSD) network.

IPC: F04D13/12
Filed: 1997-09-23
Abstract: An improved fuel transfer pump (10) is provided for relatively high flow transfer of fuel from one aircraft to another during an inflight refueling procedure, wherein the fuel transfer pump (10) includes a jet-type scavenge pump (12) for evacuating residual fuel from a fuel line (14) or manifold (15). The scavenge pump (12) comprises a venturi element (56) connected along a recirculation conduit (48) through which a small fuel flow is diverted from the high pressure discharge side of the fuel transfer pump (10) for return to the fuel tank (20). The recirculation fuel flow induces a vacuum in a suction throat of the venturi element (56), and this vacuum is coupled by a suction line (58) to evacuate residual fuel from the fuel line (14) or manifold (15) to the fuel tank (20). A flow baffle (62) is mounted along the recirculation conduit (48) downstream from the venturi element (56) to ensure flooding and priming of the scavenge pump (12).

Patent CA-2276819-A1 (CA)
Title: Fuel cell system capable of reducing electric power loss
Inventor: IWASE MASAYOSHI
IPC: B60L11/18
Filed: 1999-07-06
Abstract: A fuel cell system minimizes the power loss that may occur in a conduction passage during supply of electric power from a fuel cell to a load. A bypass connects between the input of a DC/DC converter and the output thereof, and therefore supplies power generated by the fuel cell to an inverter, bypassing the DC/DC converter. A changeover switch selectively changes the connection of the output of the fuel cell between the connection to the input of the DC/DC converter and the connection to the bypass. When the fuel cell is connected to the DC/DC converter, the power from the fuel cell is supplied to the inverter or a battery via the DC/DC converter. When the fuel cell is connected to the bypass, the power from the fuel cell is supplied to the inverter, bypassing the DC/DC converter. A cutoff switch disconnects the output of the battery from a connecting line. That is, the cutoff switch disconnects the battery from the inverter, the bypass and the like when turned off. When turned on, the cut off switch 41 connects the battery to those components.
