Patent CA-2531359-A1 (CA)
Inventor: HASKETT TREVOR
IPC: E04B1/98
Filed: 2005-12-22
Abstract: A pendulum arrangement for a Tuned Mass Damper utilizes a pair of generally equal masses, the masses being arranged so that first surfaces thereof face each other and second surfaces thereof face away from each other. A hinge structure is affixed to the first surfaces of the masses so as to hingedly connect the two masses together.  Spaced apart tension members are connected at one end thereof to a supporting frame and at the other end to the hinge structure. Each one of a pair of compression members is pivotally connected at one end thereof to an upper portion of an adjacent mass and pivotally rests on a lower support surface. The masses are supported by the tension and compression members for limited swinging movement thereof with a substantially lower period that could be achieved within the same space with a conventional pendulum.
Patent CA-2533805-A1 (CA)
Title: A method of suspending, completing and working over a well
Inventor: NISKI JOHN EDWARD
IPC: E21B33/129
Filed: 2004-08-06
Abstract: In the various methods of the present invention, reliance is placed on a first and second barrier (26) and (30) respectively positioned in a well (10) to provide well control during well suspension, completion and/or workover operations. Each of the barriers is below the depth of the lowermost end of a completion string when that string is installed in the well (10). By not placing either barrier higher up in the well-bore, both of the barriers can remain in place during suspension and completion and workover operations, thus obviating the need to use a BOP stack to supplement well control. This results in a considerable saving in drill rig time and thus significantly reduces the cost of constructing a well.

There is also provided a method for installation of pipes on a floating structure having such a storage assem+y, wherein the individual pipes (4) are provided on a production plant and are guided therefrom into the storage assembly, the floating structure being ballasted to a desired draft so that the relevant pipes can be guided directly into the correct position in the storage assembly.
Patent CA-2536457-A1 (CA)
Title: Ttl exploration technique for determining capabilities and configuration of a peer router
Inventor: COOK DAVID ANTHONY
IPC: H04L12/56
Filed: 2004-09-16
Abstract: An exploration technique allows a router to efficiently determine capabilities and configuration of a neighbor (peer) router. In addition, the technique enables peer routers of an adjacency to negotiate a capability "outside" of a protocol, such as a rout~ing protocol, before a routing session is established between the routers. In this con~text, the term "outside" of the protocol denotes that there is no field within a protocol packet (message) implementation that can be used to negotiate the capability. More~over, the inventive technique obviates the need to manually configure a router to sup~port a particular capability and interoperate correctly within a network of routers that both support and are unaware of the capability.

Patent CA-2562585-A1 (CA)
Inventor: THOMPSON DIANE O
IPC: A61K47/40
Filed: 2005-04-22
Abstract: An inhalable dry powder formulation containing SAE-CD and an active agent is provided. The formulation is adapted for administration by DPI. The SAE-CD  serves as a carrier rather than as an absorption enhancer. The average particle size of the SAE-CD is large enough to preclude (for the most part) pulmonary deposition thereof. Following release from the DPI device, the SAE-CD-containing particles dissociate from the active agent-containing particles in the buccal cavity or throat, after which the active agent-containing particles continue deeper into the respiratory tract. The physicochemical and morphological properties of the SAE-CD are easily modified to permit optimization of active agent and carrier interactions. Drugs having a positive, neutral or negative electrostatic charge can be delivered by DPI  when SAE-CD is used as a carrier.
