Abstract: La présente invention concerne un système de mesure (200) comprenant un débitmètre de Coriolis (222) et un système de régulation (224). Un liquide de base (250) circule tout d'abord à travers un débitmètre de Coriolis. Le débitmètre de Coriolis mesure la densité du liquide de base et transmet une mesure de densité de liquide de base au système de régulation. Un agent de soutènement (252) est ajouté au liquide de base pour produire un liquide de fracturation (202). Le liquide de fracturation passe alors à travers le débitmètre de Coriolis. Le débitmètre de Coriolis mesure la densité du liquide de fracturation et transmet une mesure de densité de liquide de fracturation au système de régulation. Le système de régulation détermine une quantité d'agent de soutènement dans le liquide de fracturation sur la base de la mesure de densité de liquide de base, de la mesure de densité de liquide de fracturation et de la densité de l'agent de soutènement.

Title: Combined liquid collector and mixer for mass transfer column
Inventor: ENDER CHRISTOPH
IPC: B01D3/00
Filed: 2004-04-07
Granted: 2011-11-15
Abstract: A collector (20) is used to collect and mix liquid from an overlying zone in a mass transfer column in which fluid streams are processed, such as to obtain fractionation products. The collector (20) has two or more liquid collection regions (38, 40, 42) and two or more sumps (28, 30, 32) positioned about the perimeter of the liquid collection regions. A plurality of channels and deflectors are spaced apart within each liquid collection region (38, 40, 42) and vapor passages are formed in the spacings between adjacent channels. The deflectors direct descending liquid into the channels and shield the vapor passages from the descending liquid. The channels within each liquid collection region (38, 40, 42) are arranged into interspersed sets, with one set of channels preferentially directing collected liquid into one sump and another set of channels preferentially directing collected liquid into another sump. Preferably, roughly equal amounts of liquid from each liquid collection region are deliver to the two sumps so that liquid in the sumps is of a more uniform concentration and composition. One or more of the sumps (28, 30, 32) includes a downcomer (34, 36) for directing the liquid from the sump (28, 30, 32) to an underlying zone. By mixing the liquid within the collector (20), the use of a separate mixing device can be avoided. As a result, vertical space in the column that would normally be occupied by the mixing device can be filled with packing or other internals to increase the efficiency of the column.

Abstract: Un algorithme calcule les coefficients (712) du filtre d'expansion spectral au moyen d'une valeur proportionnelle à une réciproque (720) d'un signal se propageant vers l'avant (a) et mémorise ces coefficients dans une table de consultation. Cette dernière est indexée selon un ensemble présélectionné de bits de coefficient afin de générer une fonction de coefficient de filtre. Une première partie de cette table de consultation mémorise une pluralité de valeurs discrètes au niveau de points de référence d'un segment linéaire correspondant à une approximation de la fonction du coefficient de filtre, de manière à générer une valeur discrète initiale correspondant à cette fonction de coefficient de filtre au niveau d'une valeur des bits d'ordre supérieur et une deuxième partie mémorise une pluralité de valeurs de pente indiquant une pente de cette fonction de coefficient de filtre. Un circuit linéaire effectue la décimation d'une approximation de la fonction du coefficient de filtre d'expansion en fonction de cette valeur de pente, de la valeur discrète initiale et d'un ensemble présélectionné de bits d'ordre inférieur de la valeur réciproque.

Title: Ray tracing in discontinuous multimode channel waveguides
Inventor: BIERHOFF THOMAS
IPC: G02B6/10
Filed: 2004-07-23
Granted: 2012-09-18
Abstract: The invention relates to a method for determining the transmission behaviour of an optical waveguide with a step index profile, wherein the optical waveguide is composed of guide pieces, protruding into each other, so that the surfaces of said guide pieces comprise real and virtual surfaces, lying respectively outside and inside another guide piece. The transmission behaviour is determined by geometric ray tracing, wherein the points of intersection of a ray with the surfaces of the guide pieces are determined, which are thus defined analytically, in particular, by extrusion of cross sections along an axial trajectory. A real material transition can be determined by an iterative procedure.

Title: A vector quantization apparatus
Inventor: MORII TOSHIYUKI
IPC: G10L19/12
Filed: 1997-11-06
Granted: 2012-01-17
Abstract: The device and method allow an inputted optimum gain to be converted to the vector (input) of the element of a ratio and a sum in a parameter conversion part. In a target extraction part, based on the vector obtained in the parameter conversion part, a target vector is obtained by using a decoding vector in the past stored in a decoding vector storage part and a prediction coefficient stored in a prediction coefficient storage part. In a distance calculation part, by using the prediction coefficient, a distance between the target vector obtained in the target extraction part and the code vector of a vector code book is calculated. A comparison part obtains the vector for minimizing the calculated distance and turns it to the code of the gain.

Granted: 2012-09-25
Abstract: The invention relates to a massage prophylactic and therapy appliance, which includes a suction head and a handle. The end of the suction head is in the form of a round flat opening. A blowhole is set on the wall of the handle. During the course of using the appliance, first, put the suction head snugly on the eyeball in order to vent the air of the suction head. Then, negative pressure is produced in the suction head by nipping the blowhole. When a hand grasps, or nips, the blowhole, a negative air pressure is produced. The handle is then pushed and pulled resulting in the suction head tip attracting the eyelid and eyeball and causing same to move back and forth. The suction head sucks the eyelid and the eyeball, and moves forward and backward by pulling forward and pushing backward the handle. Because the eyeballs are controlled by 6 extraoculars, when they are pulled and pushed, there will be a little distortion of the eyeballs. With this distortion, there will be a strong massage to the ciliary muscle. So the ciliary muscle will relax and get back to regulate normally. Then the eyes will relieve, so the utility model is convenient and effective.

Granted: 2013-09-03
Abstract: A system and a method are proposed for broadband communications over power lines comprising the area of the low-voltage transformer to the house connection unit and/or the electricity distribution inside the house. The new method allows for several parallel asynchronous data communications in different sub-channels with individual transmit power in each sub-channel. Sub-channel separation uses pass-band filters with high stop-band attenuation. High data rate in each sub-channel is achieved through the use of discrete wavelet multi-tone modulation. Coarse synchronization in each sub-channel and the optimization of the coefficients of the time-domain equalizer are carried out using a training sequence.
