Patent CA-2174256-A1 (CA)
Inventor: DUVAL MAURICE J
IPC: F26B3/00
Filed: 1996-04-16
Abstract: Les méthodes actuelles d'extraction du solvant des bouteilles d'acétylène disqualifiées pour le service consistent à chauffer les bouteilles après les avoir reliées à un collecteur de vapeur. Les vapeurs de solvant ainsi extraites sont recondensées grâce à un condenseur relié au collecteur. L'adjonction d'une pompe entre le collecteur et le condenseur peut éventuellement être utilisé. Dans le présent procédé de notre invention, les masses sont d'abord retirées de la bouteille. Les masses poreuses sont ensuite comprimées à froid pour réduire la proportion de solvant qu'elles peuvent absorber. Cette compression mécanique permet éventuellement d'extraire une certaine proportion de solvant. Les masses compactées sont placées dans un autoclave et recouvertes de solvant. L'air résiduel est éliminé de l'autoclave par une purge à l'azote. Un système de chauffage intégré à l'autoclave permet d'élever la température du solvant et des masses qui en sont imprégnées. La température à atteindre doit être suffisamment élevée pour assurer la vaporisation de tout le solvant contenu dans les masses sans apport de chaleur extérieur. Le solvant ajouté dont le seul rôle est d'assurer l'efficacité du chauffage est retiré de l'autoclave et transféré dans un réservoir de stockage dès que la pression de vapeur requise est atteinte. Après ce transfert, la valve reliant l'autoclave à un refroidisseur-condenseur est ouverte et le solvant imprégnant les masses se vaporise en même temps que la pression et la température des masses diminue. ~ la fin de la vaporisation, la pression cesse de diminuer alors que la température des masses a atteint une valeur légèrement supérieure à la température d'ébullition du solvant. L'injection d'azote dans l'autoclave à la fin du procédé termine l'extraction du solvant. Le coût énergétique et la durée d'extraction du solvant est considérablement réduit. L'efficacité de l'extraction est assuré et facilement contrôlable.

Title: Process for injection stretch blow molding
Inventor: TAKEUCHI SETSUYUKI
IPC: B29C49/08
Filed: 1996-09-25
Abstract: An improved method for injection stretch blowing is provided. In the process, a molten resin is injected into an injection cavity defined by an injection mold, a lip mold and an injection core to form a desired preform, where cooling time for this preform is positively reduced to form a rigid skin layer on the outer surface of the preform without increasing the thickness. After then it is released from the injection mold and transferred into a blow mold with a mouth portion being held with the lip mold while the skin layer keeps the configuration of the preform and the interior is in a high temperature state, and is stretch blow molded into a hollow molded article, e.g. a bottle of which major portion is ultra-thin at the moment when a surface temperature of the preform that rises due to its own interior temperature is significantly higher than a glass transition temperature (Tg) and is expected to reach to a peak temperature. Thereby, it is possible to allow molding of a hollow molded article having a thickness of 0.17 mm or smaller without being affected by limitations of thickness of the preform and molding temperature even in a molding process where the preform is released from the mold at a high temperature and is then immediately subjected to stretch blow molding.

Patent CA-2196987-A1 (CA)
Title: Upward deflecting support disk for electrochemical cell seal
Inventor: DEPALMA CHRISTOPHER L
IPC: H01M2/04
Filed: 1995-08-17
Abstract: A metal support disk (10) for an electrochemical cell seal exerts a resilient outward radial force against the seal to maintain seal integrity over a wide range of operating temperature and, at the same time, exerts an upward force against the bottom of the metal end cap terminal of the cell to assure electrical contact between the anode inside the cell and the terminal. The disk includes a central, circular platform (14) connected to an outer, sealing edge sealing flange (28) by an annular flexure means which permits radially inward and outward movement of the sealing edge (30) when the end of the cell is radially crimped during the sealing process. The crimping also moves the central portion (12) of the disk up which results in the upward force being exerted against the end terminal. The flexure means is a sequential series of three annular, curved ribs with the first (20) and third (26) curved downward and the second (24) curved upward. A ring (22) depending radially outward and at an upward angle from the first rib connects the first rib to the second rib and helps to prevent plastic deformation of the disk sealing.

Title: Raman fibre laser, bragg fibre-optical grating and method for changing the refraction index in germanium silicate glass
Inventor: DIANOV EVGENY MIKHAILOVICH
IPC: C03C25/105
Filed: 1996-07-05
Abstract: The invention pertains to laser technology, fibre optics and integrated optics and has industrial applicability in the field of fibre-optical and waveguide elements made from germano-silicate glass, in particular in fibre-optical Bragg and long-period gratings, dispersion compensators, integrated optical waveguides and so forth. The invention solves the problem of simplifying Raman fibre-optical lasers operating at wavelengths of 1.24 µm and 1.48 µm and enhancing the efficiency of the radiation conversion associated with Raman scattering. The 1.24 µm laser comprises a pumping source (1), a fibre-optical waveguide (2) containing 1-30 Mol % P2O5; sections of the fibre-optical waveguide containing 11-39 Mol % GeO2 form Bragg fibre-optical gratings (3, 4). The grating (3) forms an opaque dispersion mirror of an optical resonator for a first Stokes component, while the grating (4) is an output dispersion mirror for the same resonator; the first Stokes component issues at the output. In the 1.48 µm Raman fibre-optical laser, the second Stokes component issues at the output. The refractive index in the section of fibre-optical waveguide (11) is altered by directing 270-390 nm laser radiation (12) onto the section, said radiation passing through the protective polymer sheath of the fibre-optical waveguide (11).
