Abstract: Un générateur d'halogène produit un agent d'assainissement halogène afin d'assainir l'eau dans un contexte d'eau pour cuve thermale ou d'une autre eau. Un élément de montage sur une paroi coaxiale couple de manière souhaitable le générateur d'halogène à la source d'eau. Ce générateur comprend une cellule électrolytique bipolaire dans laquelle une plaque à électrode centrale tourne entre une anode fixe et des plaques cathodes. L'électrode bipolaire comprend une pluralité de pales qui provoquent l'écoulement d'eau entre l'anode et la cathode. Les pales de l'électrode rotative produisent également une circulation d'eau à travers le générateur. De cette manière, l'électrode bipolaire fonctionne comme une roue pour pomper l'eau à travers le générateur d'halogène. Les pales sont placées entre l'électrode et la cathode et elles sont suffisamment espacées de la cathode pour empêcher la formation de tartre sur celle-ci. Cependant, les pales n'entrent généralement pas en contact avec la cathode lorsqu'elles tournent. Le sens de rotation de l'électrode par rapport à la cathode peut être inversé périodiquement et/ou l'espace situé entre l'électrode et la cathode peut être diminué périodiquement afin de promouvoir l'enlèvement du tartre.

Granted: 2003-08-05
Abstract: A device for generating a magnetic field moving in at least one field plane located in a fluid to be treated and in which the gradient of the vector product between the intensity of the magnetic field and its displacement velocity induces stereochemical deformations of the molecules of the treated fluid, which may be a limestone water or a fuel. Each field plane may have a first magnetic field generator such as a pair of coils ( 10, 10' ) and a second magnetic field generator such as a pair of coils ( 12, 12' ) forming an angle theta with the first generator, both being disposed at the periphery of the pipe ( 20 ) through which the fluid to be treated is flowing. At least one of the two field generators generates a magnetic field whose amplitude is variable over time so that the resultant is a magnetic field moving in the field plane having a variable amplitude and a direction moving at an angular velocity such as to obtain the highest possible gradient of the vector product.

Title: Data transmission method in mobile communication system
Inventor: LEE HYUN-SEOK
IPC: H04W72/04
Filed: 1999-04-14
Granted: 2005-10-18
Abstract: A data transmission method in a mobile communication system is provided for transmitting user data via a common channel when the user data is generated in a suspended state. In a first embodiment, the method includes comparing a length of the generated data with a reference length for normal data transmission in an active state. When the generated data is shorter than the reference length, a generation frequency of the data generated in the suspended state is compared with a reference generation frequency for normal data transmission in the active state.      If the generation frequency of the data generated in the suspended state is lower than the reference generation frequency, a transition to a burst substate occurs to segment the data by a frame length of a common traffic channel and then the segmented data is transmitted via the common traffic channel. However, if a burst substate does not exist, the segmented data is transmitted via a previously assigned common traffic channel. In a second embodiment, the method includes, when data to be transmitted is generated in a suspended state, a transmission party which segments the data into frames having a specified length and transmits the segmented data via a previously established common traffic channel. Upon reception of the transmitted segmented frames in the suspended state, a reception party reassembles the received frames and transmits the reassembled frame to an upper layer.

Title: A capacitive measuring instrument for water level measurement in an oil tank
Inventor: TOTH FERENCZ NANDOR
IPC: G01F23/26
Filed: 2000-07-27
Granted: 2011-09-27
Abstract: A capacitive sensor for water level measurement in an oil tank is sensitive to all kinds of parasitic capacitances up to an input capacitance of a measuring instrument. In a "one port measurement" with "active guard" said parasitic capacitance of the input of a measuring instrument can be prevented by using "charge/discharge" as the measuring method and to have the measurement of the amount of charge that flows thereby take place by means of a charge-controlled oscillator. The output frequency of the charge-controlled oscillator is a measure for the amount of charge that has flown through, and that in turn is a measure for the capacitance of the sensor, which in turn is a measure for the height of the water at the bottom of the oil tank.
