Patent CA-2364285-A1 (CA)
Inventor: RACKI JEROME G
IPC: G01M11/00
Filed: 2000-03-07
Abstract: A system for measuring polarization mode dispersion (PMD) in a fiber using a  polarizer controlling the polarization state of light input to the fiber and  a polarization analyzer measuring the polarization state of light output from the fiber. Jones matrix analysis is applied to data derived from three input  polarization states and two wavelenghts of probing radiation. Performance is  improved by using incoherent light sources such as light emitting diodes in conjunction with two bandpass filters. However, a laser source and optical detector are used to align the fiber. The system is particularly useful in measuring PMD values in short lengths of fiber and mapping those values with  a long fiber from which the test fiber was cut. Preferably, the PMD is measure d for various values of twist experimentally induced in the test fiber, and th e short-length PMD value is that associated with zero-internal twist in the fiber as calculated according to a model. The fiber may also be loaded durin g measurement.

Title: Container manufacturing method and device
Inventor: DAI WEN-LONG
IPC: B27N3/08
Filed: 2001-12-28
Abstract: A container manufacturing method and device. The container manufacturing method includes steps of mixing, board-making, molding, guiding/crimping and demolding. Lower protruding guide bodies are arranged along the circumference of the mold cavity of the lower mold seat of the container manufacturing device at intervals. Upper protruding guide bodies are arranged on the press board and aimed at the intervals between the adjacent lower guide bodies. In the step of guiding/crimping, when the press board is pressed down by an oil pressure cylinder, the interlaced upper and lower guide bodies clamp and press the circumference of the board body to form regular crimps thereon. Therefore, when the upper mold block presses the board body into the mold cavity, the material can be evenly distributed and flowed so that the wall of the molded container can have uniform thickness.

Title: High-temperature fuel cell
Inventor: KAISER WOLFRAM
IPC: H01M8/2465
Filed: 2000-03-08
Abstract: The problem associated with a high-temperature fuel cell (10, 20, 30) is that the electrical serial resistance increases during the operation of said high-temperature fuel cell (10, 20, 30). This increase is caused by an oxidation of the bipolar plate (11, 21, 31) surface on the combustion gas side. An oxidation of this type is largely prevented by an oxidation buffer element which is located in the combustion gas chamber (13) and which absorbs the oxygen.

Filed: 2000-05-11
Abstract: La largeur de bande d'un système de transmission bilatérale à bande large (Figure 2) est étendue par superposition de fréquence de signaux à bande commune. Les systèmes de conversion amont et de conversion aval utilisent des filtres adaptés (27, 37, Figure 2), directement reliés, sans mélangeur, pour produire le signal superposé dans le cas du système de conversion amont (Figure 3), et sans répartiteur pour séparer les signaux superposés dans le système de conversion aval (Figure 4). Un signal d'oscillateur local à base simple est utilisé pour créer tous les signaux d'oscillateurs locaux nécessaires dans le système de conversion amont et aval. Dans un système hybride fibre et coaxial, le signal d'oscillateur local à base simple est créé par un oscillateur local redondant dans la tête de station et transmis à tous les noeuds de zone de desserte dans le signal aval. Un générateur en peigne (69, Figure 4) au niveau de chaque noeud de zone de desserte et de la tête de station (69, Figure 3) crée les signaux d'oscillateurs locaux nécessaires à une conversion amont/aval en tant qu'harmoniques du signal d'oscillateur local de base aux fins de la stabilité du système dans une large plage de fréquence.

Abstract: Reactive foils and their uses are provided as localized heat sources useful, for example, in ignition, joining and propulsion. An improved reactive foil (14) is preferably a freestanding multilayered foil structure made up of alternating layers (16, 18) selected from materials that will react with one another in an exothermic and self-propagating reaction. Upon reacting, this foil supplies highly localized heat energy that may be applied, for example, to joining layers, or directly to bulk materials that are to be joined. This foil heat-source allows rapid bonding to occur at room temperature in virtually an environment (e.g., air, vacuum, water, etc.). If a joining material is used, the foil reaction will supply enough heat to melt the joining materials. If no joining material is used, the foil reaction supplies heat directly to at least two bulk materials, melting a portion of each bulk, which upon cooling, form a strong bond. Additionally, the foil (14) may be designed with openings that allow extrusion of the joining (or bulk) material through the foil to enhance bonding.
