Title: Method and system for improving the processing time of the path selection in a high speed packet switching network
Inventor: BERTIN OLIVIER
IPC: H04L12/56
Filed: 1994-08-18
Granted: 1999-01-26
Abstract: The routing paths between origin and destination nodes in a packet  switching network  are selected more efficiently by reducing the total number of links potentially  visited  by the   routing  algorithm.     The  path  selection technique  involves two phases,  the first   phase   for   principal   links identification,  and the  second phase for selection of the best point-to-point path in the network.    Principal  paths are minimum hop count paths with a transmission delay less than a  specified  threshold.    The  algorithm  limits the screening  of the  network links in the second phase to the principal links and  excludes  the  secondary  links.    The exploration  of  a  much  smaller number  of  links has the advantage  to  considerably  reduce  the  computation time required  for the path selection.   The fact the number of principal links is generally small compared with  the  total number  of  links  potentially explored, allows to limit the additional processing time necessary in case of unsuccessful attempt.

Title: Train tire profile
Inventor: BLAZER DORMAN S
IPC: B60B3/00
Filed: 1995-08-11
Granted: 2000-10-31
Abstract: A section of a train wheel tread is formed into a continuous hyperbolic curve to respond asymptotically to changes in the path of a rail, thus,dampening lateral oscillation of the train wheels back and forth across rail. The hyperbolic curve at a minimum extends from a taping line to a wheel lift point. However, for further dampening effects the hyperbolic curve is extended from a fillet section across the taping line toward the field side of the wheel. Two tires having the same hyperbolic profile work in conjunction as a feedback system to dampen lateral oscillation while at the same time saving energy, reducing tire and rail wear.

Title: Use of isovaleramide as a mild anxiolytic and mild sedative agent
Inventor: BALANDRIN MANUEL F
IPC: A61K31/16
Filed: 1994-06-10
Granted: 2006-08-29
Abstract: Isovaleramide has been found to exhibit mild anxiolytic (anxiety-reducing) activity at low to moderate dosage levels and mild sedative activity at somewhat higher dosage levels. In contrast to certain other materials thought to be anxiolytic or mildly sedative, isovaleramide is non-cytotoxic and does not paradoxically stimulate the central nervous system. Isovaleramide is therefore useful as a mild anxiolytic and mild sedative agent which can be made available to the general public.

Abstract: A two-stage method for the preparation of polyol fatty acid polyesters is provided. The resulting polyol fatty acid polyesters are very lightly colored (i.e., colorless to slightly yellow) and have a high degree of substitution with fatty acid groups. The first stage of this two-stage method is a solvent-based esterification reaction; the second stage is an essentially solvent-free esterification reaction. In the first stage, a polyol in a solvent (e. g., sucrose in dimethylsulfoxide)) is reacted with fatty acid lower alkyl esters at relatively low temperatures using an alkaline salt catalyst. After the desired degree of esterification is obtained, the resulting partially-esterified polyol fatty acid polyesters and the solvent-containing phase are separated. The separated partially-esterified polyol fatty acid polyesters are further esterified with the same or different fatty acid lower alkyl esters in a second stage with an alkaline salt catalyst using essentially solvent-free, high temperature conditions whereby the degree of substitution is significantly increased. Most of the color bodies and other contaminants capable of producing color are removed with the solvent in the first stage and, therefore, are not present during the higher temperature reaction conditions of the second stage. The resulting polyol fatty acid polyesters, and in particular the sucrose fatty acid polyesters, are especially useful as fat substitutes in food applications and products.

Abstract: Pour refroidir un local (1), on refroidit un élément de refroidissement (3) disposé dans le plafond pendant les phases de refroidissement jusqu'en-dessous du point de congélation, de préférence jusqu'à -40  DEG C environ, de façon que l'eau de condensation qui se dépose sur l'élément de refroidissement gèle aussitôt. Pendant les phases de régénération, quand le local (1) n'est pas utilisé, on dégèle l'élément de refroidissement (3), et l'eau de condensation est amenée dans une cuve de condensation disposée sous l'élément de refroidissement (3), dont elle sort par un orifice d'évacuation (8). La grande différence de température permet d'obtenir un refroidissement intense, même avec un petit élément de refroidissement (3), grâce surtout à l'échange indirect de rayonnement entre le local (1) et l'élément de refroidissement (3) par l'intermédiaire d'un faux-plafond (9). En outre, l'air du local est déshumidifié, puisque la vapeur d'eau se dépose sous forme de glace sur l'élément de refroidissement (3), où elle reste.
