Title: Methode pour determiner l'effectif en serveurs
Inventor: MASSEY WILLIAM A
IPC: G06Q40/00
Filed: 1996-11-25
Abstract: éthode qui détermine le nombre de serveurs, en tant que fonction de temps, nécessaires pour un système de file d'attente pour serveurs à états finis, lequel est fondé sur une charge de travail prévue.  Le nombre de serveurs est choisi en tenant compte de la contrainte voulant que la probabilité de retard avant de commencer le service ne soit jamais plus élevée que la probabilité cible.  Le système de file d'attente pour serveurs à états finis est construit avantageusement selon le modèle d'un système à serveurs à états infinis, le moyen et la variance du nombre de serveurs occupés à l'heure t étant déterminés et la distribution établie de façon approximative.  En tout temps, le nombre de serveurs choisis est le plus petit afin de garder la probabilité que tous les serveurs soient occupés moins élevée que la probabilité cible.  Comme raffinement optionnel, la probabilité cible du serveur à états infinis pour la fin de la file d'attente est alors mise en relation avec la probabilité de retard réelle dans le système de serveurs à états finis.

Title: Foams made from high internal phase emulsions useful as absorbent members for catamenial pads
Inventor: DYER JOHN COLLINS
IPC: A61F13/15
Filed: 1996-01-11
Abstract: Foams capable of absorbing blood and blood-based fluids, especially menses.  These absorbent foams have high capillary absorption pressures required of absorbents used in catamenial products, yet have sufficient openness to allow free movement of the insoluble components in blood-based fluids such as menses. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs) where the volume to weight ratio of the water phase to the oil phase is in the range of from about 20:1 to about 125:1. These foams are particularly useful as absorbent members for catamenial pads.

Title: A method for enhancing fluid loss control in subterranean formation
Inventor: LAVIN WES C
IPC: C09K8/575
Filed: 1997-07-22
Abstract: The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore.          A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range.  A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles.  The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation.  The filter cake provides further fluid loss control to the permeable formation.

Title: Balanced multiple hot runner coinjection tool
Inventor: HOFSTETTER OTTO
IPC: B29C45/26
Filed: 1996-02-27
Abstract: A hot runner mould for injection moulding multilayered mouldings by simultaneously injecting various plastic melts into several cavities has a hot runner block (23a-c) slidingly supported between a top plate (21) at the side of the extruder and a hot runner plate (22) at the side of the cavities. A  joining piece (24) firmly secured to said hot runner block is coupled to a feed bush (12) slidingly mounted on the top plate (21). The hot runner plate (22) can thus expand freely with temperature changes and the compression forces of the extruder do not act upon the hot runner block (23a-c) but are absorbed by the top plate (21). The feed paths for the various plastic melts change thanks to the structure in several parts of the hot runner block (23a-c) and to the controlled expansion movements of the hot runner block (23a-c) that are identical for all cavities.

Title: Eb1 gene product binds to apc
Inventor: VOGELSTEIN BERT
IPC: C12Q1/68
Filed: 1996-05-22
Abstract: Inactivation of the APC tumor suppressor gene plays an important role in the development of both sporadic and familial forms of colorectal cancers. The majority of these mutations result in the loss of the carboxyl terminus of the APC protein. A cellular protein, EB1, that associates with the carboxyl terminus of APC both in vitro and in vivo has been identified. The EB1 gene is predicted to encode a 268 amino acid protein without significant homology to any protein with known function.

Title: Moving interferometer wafer stage
Inventor: KREUZER JUSTIN
IPC: H01L21/68
Filed: 1997-12-15
Abstract: A stage (10; 10') used for positioning and aligning a wafer (12), as used in photolithography or microlithography in semiconductor manufacturing having a plurality of interferometer laser gauges (14, 16; 14' 16') placed on a movable wafer stage (10; 10') associated with a pair of stationary orthogonal return mirrors (30, 32; 30', 32'). A beam of light parallel to the X axes is directed through a penta prism (36) to interferometer laser gauges (14, 16; 14' 16') placed on the wafer stage (10; 10') near the wafer plane through a plurality of beamsplitters (22, 24, 26; 22' 24') and fold mirrors (28; 46, 48, 50, 52). The present invention is less sensitive to rotation or twisting of the wafer stage and eliminates or reduces certain errors introduced by the rotation. Additionally, large stable return mirrors may be used, increasing the travel distance permitted by the wafer stage while reducing weight on the wafer stage. The wafer stage can be more accurately positioned and accommodate larger wafer sizes with improved positioning and alignment accuracies.

Abstract: A coding and decoding system which uses CRC check bits is disclosed. When a coding apparatus performs coding, symbol interleaving is performed after coding by an outer code of a concatenated code, and coding by an inner code is performed after CRC check bits are added. Then, upon decoding by a decoding apparatus, error detection using the CRC check bits is performed after decoding of the inner code. After symbol deinterleaving is performed, decoding of the outer code by erasure decoding or error correction is performed depending upon the number of symbols included in a frame in which an error has been detected.

Title: Electrical connector having time-delayed signal compensation
Inventor: ADRIAENSSENS LUC W
IPC: H01R24/64
Filed: 1998-08-18
Abstract: An electrical connector ¢60! achieves improved transmission performance by introducing predetermined amounts of compensation between two pairs of conductors that extend from its input terminals to its output terminals along interconnection paths. Electrical signals on one pair of conductors are coupled onto the other pair of conductors in two or more compensation stages that are ti me delayed with respect to each other. Illustratively, the electrical connector is a modular jack that is adapted to receive a modular plug ¢20!. Associated with the modular plug and the input of the modular jack there exists a known amount of offending crosstalk ¢A0!, which is approximately canceled by the two or more stages of compensating crosstalk. In a first stage, compensating crosstalk ¢A1! is introduced between the pairs, and it has a first predetermined magnitude and pha se at a given frequency. In a second stage, compensating crosstalk ¢A2! is introduc ed between the pairs, and it has a second predetermined magnitude and phase at the given frequency. Multiple compensation stages are needed because, at high frequencies, compensating crosstalk cannot be introduced that is exactly 180 degrees out of phase with the offending crosstalk because of propagation delay. The electrical connector ¢60! is constructed using a multi-layer printed wiring board ¢600! having input and output terminals where connection to metallic wires is made. These terminals are interconnected on the printed wiring board by metallic paths that are arranged to provide multiple stages of compensating crosstalk. When the connector ¢60! is joined to a plug ¢20!, the near-end crosst alk of the combined structure is extremely low at frequencies up to at least 200 MHz

Title: Spark ignition engine with pressure-wave supercharger
Inventor: WENGER URS
IPC: F01N3/24
Filed: 1997-03-03
Abstract: The invention relates to a spark ignition engine (1) having a pressure-wave supercharger (5) and a three-way catalyst (4). To remove the pollutant constituents HC, CO and NO x in an efficient manner, an oxidation catalyst (12) is connected downstream of the three-way catalyst, said oxidation catalyst being arranged between the outlet of the supercharger and the exhaust (11). The oxidation catalyst can, consequently, function with excess air which comes from the supercharger. The above combination reduces pollutants substantially with a high specific output of the engine.
