Title: Optical fiber connector in which an optical fiber is protected even when connection is not made
Inventor: USUI MITSUO
IPC: G02B6/38
Filed: 1999-06-29
Abstract: In an optical fiber connector (1), an outer member (2) holds a portion of an optical fiber (4A) remote from its connecting end which is connectable to a connecting end of a counterpart optical fiber. An aligning member (3) is held by the outer member so as to be movable along the optical fiber. The aligning member carries out positioning of the connecting end of the optical fiber.

Patent CA-2282111-A1 (CA)
Inventor: MEARS ARTHUR WILLIAM
IPC: B65D63/10
Filed: 1999-09-14
Abstract: The present invention discloses a releasable and reusable tie strap for bundling a group of wires together.      A plastic tie strap has a clip head attached to the strap.      The clip head has a hinged cover which can be releasably closed over the strap. The clip head has a ratchet tooth which engages ribs on the strap. The hinged cover is closed over the strap to cause the ratchet tooth to engage the ribs. The strap may then be drawn through the clip head to achieve the desired tightness around the object it is tying.      The ratchet tooth prevents withdrawal of the strap from the clip head until the hinged cover is opened. Thus, the device may be opened and reused. Alternate embodiments utilize pins in lieu of the hinged cover.

Title: Doucine aqua foam
Inventor: PIUZE STEPHANE
IPC: E04H4/00
Filed: 2000-02-03
Abstract: PRÉCIS  Depuis que les piscines hors terres existent, il y a toujours eu un problème avec le remblais dans le bas du mur intérieur qui vient protéger la toile pour l'empêcher de venir en contact avec les pièces métalliques de la structure qui pourraient endommager celle ci.  Il existe plusieurs types de remblais. -Remblais en terre -Remblais en sable -Remblais en poussière de pierre  Dans chaque cas le même problème se pose, le remblais étant constitué d'un matériel gélif, lorsque la piscine est soumis a un gel, il devient très dur et pratiquement non compressible, la masse de glace à l'intérieur de la piscine viendra se déposer sur ce remblais qui par la suite viendra endommager le mur, la structure et la toile de la piscine peut importe la dimension du remblais. Même pour les endroits ou le gel n'est pas présent les remblais de ce type se déforment, se mine avec les pluies, se font détériorer par les insectes, etc. Un remblais en mousse de polystyrène expansé (EPS) a été mis sur le marché mais toujours en gardant quelques désavantages des remblais mentionnés si haut.  Après avoir installé plus de 4000 piscines hors terre j'ai pû concevoir un coin protecteur préfabriqué (Aqua Faom) qui élimine les inconvénients des autres types de remblais.  Ce type de coin protecteur agira comme un amortisseur pour le bloc de glace et même dans les endroits ou il n'y a pas de gel, il ne se fera pas détériorer par les facteurs naturels ou autres, car il est conçu d'un matériel compressible ayant une mémoire de sa forme originale, c'est à dire qu'une fois la pression enlever sur la pièce elle reprendra sa forme initiale.

Title: Method for suppressing multiple drug resistance in cancer cells
Inventor: NOBORI TSUTOMU
IPC: C12Q1/34
Filed: 1998-10-23
Abstract: Methods for treating and preventing the onset and maintainance of multiple drug resistance (MDR) in animals undergoing chemotherapy for cancer are provided wherein target cells are depleted of adenosine 5'-monophosphate (AMP) and adenosine 5'-triphosphate (ATP) such that the cells are unable to support P-glycoprotein activity. One method obtains a population of target cells from a host and assays for loss of methylthioadenosine phosphorylase (MTAse) activity. MTAse catabolizes methylthioadenosine to adenine for endogenous salvage incorporation into the intracellular AMP pool. MTAse deficient cells are treated with a purine synthesis inhibitor, such as L-alanosine, which starves the cells of adenine and suppress P-glycoprotein activity. MTAse competent cells are also treated for MDR with purine synthesis inhibitors. MTAse competent and deficient cells are also treated for maligancy with other anti-cancer drugs. The figure depicts the effect of chemotherapeutic drugs on the cell lines.

Patent CA-2310832-A1 (CA)
Inventor: KLEFENZ FRANK
IPC: G06F17/00
Filed: 1998-11-13
Abstract: A method and apparatus to segment-wise detect and bring into coincidence signal waveforms which can be converted into monotone and continuous trajectories, in particular for purposes of real-time pattern recognition, localization and monitoring optical and acoustic signals and to determine transit-time differentials.      The desired monotone and continuous trajectories are made to coincide in translation-invariant manner with the key signal waveforms which are also storable in reconfigurable manner. The said method and apparatus therefore detects in a very short time said trajectories with high accuracy of measurement. Even in other applications (Fig. 3), the determination of transit-time differentials implemented by the method of the invention takes the form of detecting key signal waveforms in the upper or lower signal detection unit C1a or C1b and in further processing the data in the subsequent multi-coincidence unit C2, shift-invariant parallel multi-template matching being carried out in the detection units C1a and C1b, wherein the trajectories are correlated in parallel and a set of transit-time differentials in the form of an output vector D being emitted from the subsequent multi-coincidence unit C2. The method is suitable to accurately determine trajectories and accordingly is useful for instance to localize signal sources in space, to measure displacement trajectories, to measure speed and acceleration, etc.
