Title: Procede de formation de bandes a partir d'une suspension dans l'air de matieres fibreuses
Inventor: DROBOSYUK VIKTOR MIKHAILOVICH
IPC: D21F1/02
Filed: 1999-10-25
Abstract: Cette invention se rapporte à un procédé et à un appareil de fabrication du papier par une technique aérodynamique. A cet effet, une suspension dans l'air est acheminée sur une toile de formation en mouvement, disposée de façon à former un angle par rapport à l'écoulement de la suspension dans l'air. Ensuite, le composant air est retiré par un dispositif d'aspiration situé du côté opposé de la toile de formation. Les opérations d'amenée de la suspension dans l'air et de retrait de l'air sont effectuées dans un canal à écoulement direct, dans lequel la valeur de la force d'aspiration est réglée de façon à augmenter dans le sens du déplacement de la toile de formation, pour que la force d'aspiration appliquée à la matière fibreuse dans la couche de surface de la bande en cours de formation soit approximativement la même le long de la toile de formation dans la zone de formation de la bande. Ainsi, une faible concentration de matière fibreuse dans la suspension dans l'air est maintenue jusqu'au moment où la suspension atteint la toile de formation, opération qui est suivie par un retrait efficace de l'air ne produisant pas de tourbillons à proximité de la toile de formation, les fibres étant maintenues de façon fiable sur la toile et les risques de cisaillement des fibres tombant sur la toile étant exclus. Ces facteurs, combinés, permettent la production de papier avec un degré d'uniformité élevé à une vitesse de production élevée.

Abstract: The spark plug has a top end portion of a main metal shell that is almost cylindrical on an outer circumferential face without having a plug attaching external thread screwed into the cylinder head. Further, the plug hole formed in the cylinder head has a top end counterpart corresponding to the top end portion of the main metal shell. And in the mounting structure of the spark plug into the cylinder head (plug hole), the clearance amount (.PHI.D - .PHI.d) satisfies a relation .PHI.D - .PHI.d <= 0.15 (unit: mm) where the outer diameter of the top end portion of the main metal shell is .PHI.d and the hole diameter of the top end counterpart of the plug hole is .PHI.D.

Abstract: L'invention concerne un procédé de préparation de zéolites X et LSX agglomérées avec un liant et dont environ 50 à environ 99% des sites échangeables sont occupés par des ions lithium.  Ce procédé consiste à procéder à l'échange lithium d'une partie des cations échangeables de la zéolite de départ par mise(s) en contact de ladite zéolite répartie dans un carrousel d'au moins deux récipients sous forme de lit fixe agencés en série de manière interchangeable, avec une solution de composés de lithium acheminée à travers le carrousel dont la succession des récipients est modifiée de manière cyclique à des intervalles de temps donné. Lorsque le taux d'échange en lithium souhaité est atteint pour la zéolite du premier récipient, celui-ci est dissocié du carrousel et la zéolite qui y est contenue est débarrassée de la solution de composés lithium par lavage puis déchargée et éventuellement remplacée par une nouvelle charge de zéolite à échanger. Avantageusement, on pratique une purge du flux correspondant à l'excès de lithium mis en oeuvre en la distinguant de l'effluent généré par le carrousel et on extrait du carrousel, d'abord le flux correspondant à la percolation en sortie de la colonne de tête du carrousel, et ensuite le flux correspondant à la percolation en sortie de carrousel.  Ce procédé permet d'atteindre un haut niveau d'échange en lithium avec un rendement en lithium fortement amélioré par rapport aux procédés de l'art antérieur.

Title: Monolithic serial optical parametric oscillator
Inventor: FUKUMOTO JOSEPH M
IPC: G02F1/39
Filed: 2000-12-18
Abstract: An arrangement (10) for efficiently shifting energy received at a first wavelength and outputting the shifted energy at a second wavelength. The arrangement (10) includes a laser (12) and an optical parametric oscillator (14) of unique design. The oscillator (14) is constructed with an energy shifting crystal (20) and first and second reflective elements (16) and (18) disposed on either side thereof. Light from the laser (12) at a fundamental frequency is shifted by the crystal and output at a second wavelength. The second wavelength is a primary emission and induces a secondary emission of energy in the crystal. A novel feature of the invention is a coating applied on the reflective elements (16 and/or 18) for minimizing the secondary emission. This constrains the energy to be output by the arrangement (10) at the wavelength of the desired primary emission. In the alternative, the arrangement (10) may be optimized to output one or more of the secondary emissions.
