Title: Procede et systeme de commande de la puissance de transmission d'appareil dans un reseau de communication sans fil
Inventor: CHEN XIXIAN
IPC: H04B1/7097
Filed: 2002-01-10
Abstract: L'invention concerne un procédé et un système de commande de puissance en boucle fermée dans un réseau de communication sans fil. Un signal reçu est désétalé, la puissance de signal du signal reçu désétalé est estimée, et la puissance de bruit du signal reçu désétalé est estimée. L'estimation de la puissance de bruit consiste à multiplier le signal reçu désétalé par un code de bruit orthogonal afin d'éliminer le signal reçu, à accumuler le signal reçu désétalé multiplié sur une trame et à déterminer un rapport signal sur bruit du signal reçu au moins partiellement par division de la puissance de signal estimée par la puissance de bruit estimée. Un bit de commande de puissance inverse est déterminé sur la base du rapport signal sur bruit déterminé.

Abstract: The electroviscous fluid is a suspension composed of a finely divided dielectric solid dispersed in an electrically nonconductive oil. The viscosity of the fluid increases swiftly and reversibly under an influence of electric field applied thereto and the fluid turns to a state of plastic or solid when the influence is sufficiently strong.  The electroviscous fluid of the present invention comprises 1-60% by weight of a dispersed phase of carbonaceous particulates having average particle size of 0.01-100 micrometer, and 99-40% by weight of a continuous liquid phase of an electric insulating oil having a viscosity of 0.65-500 centistokes at room temperature.  The electroviscous fluid exhibits an excellent electroviscous effect even at a high temperature with a low electric power consumption together with maintaining the improved electroviscous effect for a long period of time.

Title: Process for the preparation of 2,2,2-trichloro-1-hydroxymethyl phosphonic acid diesters
Inventor: CSABA ATTILA
IPC: C07F9/40
Filed: 1989-10-10
Abstract: ABSTRACT    A process for the preparation of 2,2,2-trichloro-1-hydroxyethyl phosphonic acid esters, typically the dimethyl ester known as trichlorfon, wherein a three stage reaction is used, without isolating the intermediate products, and wherein the reactants taken for the process are phosphorus trichloride, an alkanol (which can be phenol), water and trichloroacetaldehyde.  The reaction is carried out in a hydrocarbon, typically benzene, at a temperature of about 80°C.  The presence of the water both moderates the reaction, and substantially reduces the formation of methylchloride as a by-product.

Abstract: A prosthesis, useful as an implant, comprises a peripheral silicone membrane (1) filled with a number of small individual closed cells (5) with a thin silicone membrane and filled with a biocompatible fluid, said small cells (5) being distributed around a central compartment (4) delimited by a closed, relatively thick silicone membrane (6,7), said compartment being filled with an adjustable quantity of a physiological solution.      The prosthesis can be adjusted as to its volume and shape by insertion or extraction of liquid into, or from, the central compartment through a self-sealing silicone membrane without the need of surgery. The prosthesis also overcomes the danger of major loss of fluid due to leaking or rupture of the membrane.

IPC: H04N5/93
Filed: 1989-10-13
Abstract: A system for determining the sequential position of video fields of a received video signal that was derived from a film having successive image frames in accordance with the 3:2 pulldown method, wherein the video fields are produced at a greater rate than the film frame rate and in a predetermined repetitive sequentially varying relationship to the film frames wherein at predetermined positions in the sequence a video field is identical to the video field that preceded it by the duration of two video fields. The system includes means for delaying each field of the received video signal; means for comparing each received videofield with a video field that has been delayed by the duration of two video fields; and means for comparing the results of a successive number of said comparisons with the predetermined sequence to determine when identical fields are located in only said predetermined positions in a sequence of the compared received video fields. An video signal processing system is synchronized by said determination that identical fields are located in only said predetermined positions in a sequence of the compared received video fields, for inserting indications of sequential video field position in the vertical blanking intervals preceding video fields that are received subsequent to said synchronizing determination. A counter times said comparisons of said compared results with the predetermined sequence and provides an indication that the received video fields were not so derived from film when a determination that identical fields are located in only said predetermined positions in a sequence of the compared received video fields, is not made within a predetermined time. This indication is used to set the mode of operation of a system for providing a progressive-scan video display in accordance with whetheror not the received video signal was derived from film.

Abstract: ABSTRACT       The present invention is a liquefaction process for atmospheric gases.  In the process, one or more atmospheric gas streams (e.g., air, nitrogen, etc.) are compressed in a compression zone to provide both an intermediate stream and a high pressure stream.  The high pressure stream is then cooled and at least a portion of it is expanded to provide refrigeration.  The remaining high pressure stream is then further cooled and expanded whereby it is partially liquefied and separated into a vapor stream and a liquid atmospheric gas product stream.  The intermediate pressure stream is cooled and at least a portion of it is expanded to provide refrigeration.  The remaining intermediate pressure stream is further cooled and combined with the expanded portion of the high pressure stream and expanded to provide refrigeration.  The discharge from this expansion, the vapor stream, and the discharge of the expansion of the portion of the intermediate pressure stream are warmed and recycled to the compression zone.  The process of the present invention can include the use of companders and a dense-fluid expander.

Filed: 1990-05-10
Abstract: PIPETTE PUMP                     ABSTRACT OF THE DISCLOSURE           A pipette pump for pipetting fluid includes an elongated hollow barrel and a pump mechanism at one end of the barrel.  The pump mechanism includes a compressible portion which is actuated to fill the pipette barrel.     Thereafter, the pipette barrel is vented to the atmosphere to bypass the pump mechanism such that the fluid in the pipette barrel is discharged by gravitational forces and atmospheric pressure rather than by actuation of the compres-sible portion of the pump mechanism.  The pipette barrel may be repeatedly vented to discharge the contents of the pipette in a series of aliquots.  The pump mechanism, when compressed and not bypassed, provides rapid, positive displacement discharge of the contents of the pipette.

Title: Edible spread
Inventor: GABRIEL GERHARD
IPC: A01J17/00
Filed: 1990-10-09
Abstract: Abstract EDIBLE FAT COMPOSITION       Edible spreads are prone to microbiological spoilage by a number of organisms, including molds and bacteria as well as by physical changes occurring on storage  While the growth of these organisms and consequently the onset of spoilage can be inhibited by the use of preservatives, some consumers find preservatives unacceptable.  We have determined that in edible fat products wherein the fat phase comprise a homogenous dispersion of fine crystals and in which the fat phase is essentially free of crystalline aggregates spoilage is greatly reduced.  Anhydrous products can be produced by melting the fat, substantially in the absence of ah aqueous medium, cooling the melted fat to a temperature at which partial crystallization occurs, homogenising the partially crystallised fat, and, cooling the homogenised fat to further crystallise the fat.  By means of a modified process it is possible to produce comprising 50-60% fat phase, 40-50% water phase, 0.1-1% lecithin, 0.01-1% salt, being essentially free of monoglycerides, proteins and sorbate salts, which are stable on storage.
