Abstract: Cette invention se rapporte à des colorants polysulfonamide anthraquinoniques que l'on obtient à partir de chlorures de pyrosulfuryle contenant des chromophores anthraquinoniques en les faisant réagir avec diverses diamines. Ces colorants polysulfonamide anthraquinoniques servent à colorer une grande variété de produits tels que plastiques, fibres, films, cosmétiques, lotions et crèmes de beauté, encaustiques, cires, colorations capillaires, revêtements, peintures, encres, etc. et ils s'avèrent particulièrement utiles dans les cas d'utilisations finales où la sublimation, la migration, l'extraction et l'exsudation des colorants utilisés à ce jour constituent des problèmes.

Abstract: Ce système informatique sert à déterminer un ensemble de prix d'ouverture pour un certain nombre de séries d'options échangées sur un marché d'options et à attribuer des déséquilibres dans les ordres publics, lors de l'ouverture du marché. Des contrepartistes entrent une position actuelle, une position cible souhaitée, ainsi que des ordres (104) de contrepartistes, pour des séries d'options provenant de terminaux de contrepartistes. Un système d'entrée d'ordres reçoit des ordres publics (102) pour des séries d'options. Un gestionnaire (2) détermine, pour chaque série d'options, un ensemble de volatilités implicites (prix) qui va servir à maximiser un volume pondéré d'échanges sur toutes les séries d'options, lors de l'ouverture du marché. Des contrordres qui correspondent au prix d'ouverture sont alors exécutés. En cas de déséquilibre résiduel d'ordres publics non exécutés, ce déséquilibre est assigné à des contrepartistes de la pluralité de contrepartistes, de façon à minimiser une mesure cumulée de déviation entre la position cible désirée et la position actuelle de chaque contrepartiste. Ce système peut s'appliquer à un marché d'options, ce terme recouvrant toute installation de gestion d'un marché hors cote d'options.

Title: Echo canceller with silence detection
Inventor: EL MALKI KARIM
IPC: H04B3/23
Filed: 1997-09-29
Abstract: An echo cancellation method and apparatus (20) determines whether a window W(m) of samples on an incoming communications path (30) contains silence, the window W(m) including the sample obtained at time t(m) and prior samples. If the window W(m) contains silence, coefficients of an adaptive filter (52) of the echo canceller (20) are set to silence detection values prior to receipt of a sample at time t(m+1). If the window W(m) does not contain silence and there is no double-talk, the sample obtained at time t(m) is used to update coefficients of the adaptive filter; the adaptive filter as updated generates an echo estimate after a sample is obtained at time t(m+1); and, the echo estimate is used to modify a signal on an outgoing communications path (32).

Abstract: A collector structure (20) for collecting tissue or bone
from a dental patient during a dental implant procedure
generally includes a housing (30) which includes a cover
member (34) and a support member (32). A porous filter medium
(24) is mounted on the support member (32). The support
member (32) is mountable within the cover member (34) with a
gasket member (36) positioned therebetween. A passage (50,
86) is provided through the collector structure (20) to allow
the passage of fluid material through the collector structure
(20). The support member (32) has a pair of spaced-apart,
opposed filter support arms (62) for removably supporting a
substantially flat section of filter medium (24) so that the
filter medium (24) overlies an inlet passage (50) such that
fluid material passing through the collector structure (20)
must pass through the filter medium (24) which will filter out
any bone or tissue specimens. The filter medium (24) is
removable from the support structure (32) so that it can be
positioned in a flat-orientation to facilitate the removal of
bone or tissue specimens therefrom. Once removed, the filter
medium (24) cannot be reattached to the support structure
(32). A pair of latch arms (46) releasably secure the cover
member (34) and the support member (32) together. The gasket
member (36) provides an integral one-way valve which normally
blocks the inlet passage (50) and can be moved out of
association with the inlet passage (50) to provide a path for
the flow of fluid material through the collector structure
(20).

Abstract: A process for device fabrication and resist materials that are used in
the process are disclosed. The resist material contains a polymer in
combination with a dissolution inhibitor and a photoacid generator (PAG).
The dissolution inhibitor is the condensation reaction product of a saturated
polycyclic hydrocarbon compound with at least one hydroxy (OH) substituent
and a difunctional saturated linear, branched, or cyclic hydrocarbon
compound wherein the functional groups are either carboxylic acid or
carboxylic acid chloride groups. The polymer optionally has acid labile
groups pendant thereto which significantly decrease the solubility of the
polymer in a solution of aqueous base. A film of the resist material is formed
on a substrate and exposed to delineating radiation. The radiation induces a
chemical change in the resist material rendering the exposed resist material
substantially more soluble in aqueous base solution than the unexposed
portion of the resist material. The image introduced into the resist material
is developed using conventional techniques, and the resulting pattern is then
transferred into the underlying substrate.

Abstract: A centrifugal separtor for non-cohesive particulates, such as are found in transmission oils and hydraulic liquids, rather than the cohesive combustion products found within internal combustion engine lubricants, consists of a housing enclosing a vertical spindle on which spins a liquid reaction driven rotor container. The container is divided internally by inwardly extending partition wall into separate outflow chambers. Non-cohesive particulates which separate from the liquid, and are held against the peripheral side wall by centrigual force during rotation, slump therefrom in the absence of rotation and risk forming a slurry that gets carried to the outflow chamber. An upwardly extending, outwardly inclined barrier wall forms a contaminant retention region with a restricted neck defined by the separation of the barrier wall edge from the side wall, that permits deposits on the barrier wall to carry to the peripheral side wall and spread across it during rotation, and does not interfere with slumping absent rotation and inhibits the slumped material from being washed into the outflow before rotation recommences.
