Title: An adhesive-free lens-attached optical fibers to optical waveguide packaging system
Inventor: BENHAM VICTOR
IPC: G02B6/30
Filed: 1999-12-21
Abstract: A method of forming a package of an optical waveguide and optical fibers. The optical fibers are positioned between two compressive material layers and, with the fibers located in alignment grooves with one of the compressive layers between fibers and the groove surface, compression is applied. For compression, two rigid substrates, disposed one disposed one on each side of the arrangement of fibers any compressive. layers, are urged towards each other. As the compressive layers are being compressed, the fibers are urged laterally into the grooves and into optical alignment with the waveguide. Preferably, two rigid plates, one on each side of the above assembly, are urged toward each other for compression. The plates are urged together at plurality of localized positions so that the force applied may be adjusted individually at each of these locations so as to more precisely align the fibers and waveguide. The invention also include a package made by the method.

Patent CA-2296827-A1 (CA)
Inventor: ROBLES ANTONIO T
IPC: C22B11/08
Filed: 2000-01-18
Abstract: A process is disclosed for the recovery of gold and/or silver values from activated carbon, wherein they are adsorbed as cyanide complexes. The process uses an eluant containing sugar. The process allows the eluant to pass through fresh carbon twice, thereby reducing the volume of the gold-loaded eluant.  This, in turn, reduces the size of the electrowinning or zinc precipitation circuits. The process also improves elution efficiency when barren electrowinning solution is recycled in the elution process.

IPC: G06F17/30
Filed: 2000-06-02
Abstract: A context manager supports creation, storage and retrieval of data to implement state maintenance in a vault process using "scoping" of multiple levels of storage.  A user request is initiated by invoking an URL with embedded Application Domain and Instance Context. The URL request is processed by a Vault Supervisor to obtain a user ID and password to initiate a vault process running in a secure vault for the user. On vault process start up, access to the vault encryption/decryption keys are made available to the request. A global context file stored on disk is decrypted and read in to memory. If the global context file does not exist, a new global context file is created on disk. For each Application Domain, the application context is decrypted and read in to memory. If an application context file does not exist, a new application context file on disk is created based on the request. All Instance Context files are scanned to determine if they have expired. If they have expired, they are deleted from the disk. At this point, the vault process is in a steady state ready to process the user request. A dispatcher running in the vault responds to a user request after all posted data as well as CGI variables are available. The dispatcher parses the URL and determines the Application Domain as well as the Instance Context. If no previous Instance Context exists, the dispatcher generates a new random value for the new instance context. If the Instance Context does exist, the vault process will then attempt to load a "local variable pool" from memory or from disk. All CGI and post-data are stored in the local variable pool for the given Instance Context and Application domain. Any previous values will be overwritten so that any CGI or post-data needed across requests are stored in specific user variables. The dispatcher will then find an idle vault process thread to service the request. This thread will be instantiated with the Application Domain and the Instance Context. The context manager will process the thread and import the application function from disk after decryption. The local instance function will be imported from disk after decryption and loaded into the application function running in the vault process. After processing. a return code is generated by the application indicating whether the local instance should be retained for the next user request.

Abstract: An apparatus and method to determine a position of a mobile wireless transceiver. The invention merges GPS position location and wireless communication technologies to achieve a precise position location in dense urban and other environments when line-of-sight to the satellites is somewhat obscured.

In a most general sense, the inventive method includes the steps of receiving at a base station (10) a first signal transmitted from a first GPS satellite and a second signal transmitted from a second GPS satellite. The mobile's transmitter (200) and receiver (100) are adapted to receive these GPS signals as well and transmit a third signal to the base station in response thereto. The base station (10) receives the third signal and uses it to calculate the position of the wireless unit (20).

Title: Retrofitting existing concrete columns by external prestressing
Inventor: SAATCIOGLU MURAT
IPC: E04G23/02
Filed: 1999-03-23
Abstract: A large number of existing reinforced concrete structures, such as buildings and bridges, if subjected to abnormal loads, such as those expected during earthquakes or bomb blast, may experience significant inelasticity in their critical regions. It is economically not feasible to replace the entire existing infrastructure with new and improved structures; retrofitting provides the only solution to the problem of seismically and otherwise structurally deficient existing structures. A new retrofitting process has been developed to improve strength and deformability of existing reinforced concrete columns (10). The process involves determining column (10) critical regions, identifying critical stresses that may lead to brittle shear and/or compression failures, determining external prestressing to overcome some of these stresses and to provide lateral confining pressure to improve the ductility of compression concrete. External prestressing is provided by placing prestressing hoops (14) around the column (10) at predetermined locations. Each hoop (14) includes a strand (16) that encircles the column (10) with its ends fixed under tension to an anchor (1S). The invention is applicable to concrete columns (10) of any geometric cross section. For circular columns prestressing may be applied directly on the surface of the column (11) by the strands (16).      For columns (10) with rectilinear geometry such as square, rectangular and other polygonal cross-sectional shapes, additional hardware (76, 77, 85, 86) is necessary between the strand (16) and the flat surfaces (74) to distribute the prestressing force as evenly as possible on the surfaces (74) of the column (10). External protection of hardware against corrosion, fire and vandalism may be carried out by means of fiber reinforced or plain concrete jackets, shotcreeting or similar sprayed applications of cement based materials (62), and different types of paints.
