Granted: 1999-06-15
Abstract: A process for activating vulcanized waste rubber particles by treating the waste rubber particles with a rubber latex and a curing system and drying the treated waste rubber particles. The waste rubber particles are preferably treated with 1 to 4 % by weight of rubber latex (calculated as dry substance) and 0.5 to 3 % by weight of sulfur as vulcanizing agent, both being calculated on the waste rubber panicles. The treatment is carried out conveniently by mixing the waste rubber particles with the vulcanizing agent, adding the latex at a temperature of from 70 to 90°C and stirring the obtained mixture for 5 to 10 min. so as to evaporate the water. Also disclosed are processes for producing a rubber-like article by molding the activated waste rubber particles, whether or not mixed with a non-vulcanized rubber compound, while applying heat and pressure.

Abstract: Un système sonore numérique pour des films de projection animée utilise un code de temps numérique (20) sur le film (4) afin de déclencher le transfert des données sonores d'une mémoire audio numérique (40) vers une mémoire FIFO (42), (premier entré, premier sorti). Les données audio numériques sont lues de la mémoire FIFO et reproduites dans la salle à une cadence constante, les éventuels sauts du code de temps numérique étant résolus en effectuant un saut correspondant dans la mémoire audio numérique mais non dans la mémoire FIFO. La lecture de la mémoire FIFO et la synchronisation des convertisseurs numériques/analogiques (CN/A 1-4) utilisés pour la reproduction en salle sont synchronisées sur le réseau à courant alternatif (54) qui alimente le projecteur de la salle, ce qui permet d'obtenir une reproduction audio ininterrompue même si les entrées de code de temps sur le film sont oblitérées. La mémoire FIFO ne nécessite qu'une capacité suffisante pour gérer le temps d'accès en mémoire audio maximum, et peut être très petite.

Title: Electrochemical surface analysis using gel electrolyte
Inventor: WHITE JOHN T
IPC: G01N27/416
Filed: 1995-10-27
Granted: 2006-05-30
Abstract: Electrochemical surface analysis using a deoxygenated gel electrolyte provides advantages over a liquid electrolyte in processes such as sequential electrochemical reduction analysis. In sequential electrochemical reduction analysis, a solderable portion of an electronic component or circuit board to be tested is placed in contact with a deoxygenated gel electrolyte such as a borate buffer solution having a gelling agent. The gel electrolyte prevents capillary attraction up or along a lead of the component so that the power source cathode lead does not contact the electrolyte and electrochemical analysis can be localized to the area of interest, such as the portion of the component lead to be soldered. Interfering effects of atmospheric oxygen are minimized for deaerated gel electrolytes because convection mixing is practically absent and diffusion is generally a very slow process in a gel. For a gel electrolyte saturated with inert gas and including an oxygen scavenger, brief exposure to oxygen as test specimens are changed does not affect the electrochemical analysis. In some cases, it is be possible to perform electrochemical analysis in ambient atmosphere rather than in an inert gas as generally required by the prior art.

Title: Hydraulic cylinder for grain augers
Inventor: PLETT BENJAMIN
IPC: F15B15/20
Filed: 1996-09-12
Granted: 2000-11-14
Abstract: A grain elevator auger uses a hydraulic cylinder incorporating a checkvalve.  This checkvalve enables the volume of hydraulic fluid required to raise the elevator to be reduced to that required to replace the extended piston rod, instead of the full volume of the cylinder.  The necessary capacity of the tractor hydraulic system reservoirs which are used to raise the elevators are similarly lessened.  The checkvalve prevents hydraulic pressure retracting the piston, pressure is equalized on both sides of the cylinder piston, which then retracts slowly under the weight of the elevator, rather than rapidly under hydraulic pressure.

Abstract: Une focalisation automatique fiable est nécessaire pour l'obtention de mesures précises de composants cellulaires colorés fluorescents à partir d'un système capable de balayer de multiples champs de microscope. La focalisation automatique pourrait s'effectuer directement avec des images de fluorescence, mais en raison des sous-produits de photoblanchiment et de fluorescence destructifs, il est préférable de réduire au minimum l'exposition à la fluorescence pour les échantillons et les cellules vivantes photosensibles. On pourrait supprimer totalement ce problème d'exposition en utilisant la microscopie à contraste de phase mise en oeuvre avec les mêmes équipements optiques que dans la microscopie à fluorescence. On a évalué les fonctions de la focalisation automatique à contraste de phase et à fluorescence avec le système selon l'invention, puis la compatibilité de la focalisation à contraste de phase pour la microscopie à fluorescence. Le système de focalisation automatique selon l'invention prévu pour la microscopie à balayage peut être utilisé à des vitesses aussi élevées que 0,25 s/champ sans perte de précision. La vitesse de la focalisation automatique peut être encore augmentée par une image de volume obtenue par l'observation d'un objet d'image à chaque plan d'image d'une pluralité de plans d'image, lesquels sont déplacés verticalement les uns par rapport aux autres. Une représentation d'image électronique est obtenue à chaque plan d'image. Les plans d'image sont balayés sur l'objet d'image, les images étant ensuite alignées de manière temporelle dans un tampon qui comprend une image de volume contenant des images au niveau des plans d'image alignés par le tampon. Le plan d'image présentant la meilleure focalisation est sélectionné et un objectif de microscope est positionné automatiquement au niveau du plan sélectionné.

Abstract: The invention relates to a device and a process for gravitation measurement with an acceleration sensor fitted on a moving support, a satellite navigation receiver and a computing unit in which use may be made of several acceleration sensors instead of one for vector gravimetry, the satellite navigation receiver must show the spatial location as well as the position in order fully to indicate the inertial acceleration and finally the computing unit may finally be used off-line for the combination of the measured total and inertial acceleration to determine the gravitation. The numeric filtering of the accelerations measured is considerably improved by the drafting of filter coefficients best suited to the stochastic properties of the gravitational field over a "physically blind" low-pass filtration. The invention makes it possible to use simpler and more economical acceleration meters, to find the vector gravimetry, i.e. the full gravitation vector, and determine finer structures of the earth's gravitational field by aircraft/ship gravimetry.
