Title: Measuring device and process for determining the level in fluid containers, preferably for tank installations, and use of a sound waveguide.
Inventor: DAEGES JOHANNES
IPC: G01F23/28
Filed: 1990-08-22
Abstract: In a level measuring device for containers filled with fluid, preferably tanks in tank installations, the fill level height h is determined from the transit time of ultrasound pulses which are emitted by first sound pulse transmitters along a main measuring path extending from the bottom region of the tank to the fluid surface and are reflected from the fluid surface to first sound pulse receivers. Temperature sensors are provided for finding the temperature distribution throughout the fill level height h. Processing the measurements provides a mean temperature TM in the fluid volume. In addition to the main measuring path there is a reference path in the fluid volume, with second sound pulse transmitters and receivers and a reference temperature sensor for measuring a reference temperature TRef. The reference path makes it possible to find the sound velocity v*(TRef) in the fluid volume at the reference temperature TRef from the measured difference in transit time, so that a temperature-corrected sound velocity v(T) in the fluid volume: v(T)=v*(TRef)[1+Kkx DELTA T], and thus a temperature-corrected fill level height h(T)=v(T)xtH, are found, in which  DELTA T=TM-TRef, and Kk is a medium-dependent correction factor. The measuring device and a process for determining the fill level use a measuring tube with first and second sound waveguides.

Abstract: Dans le cas de machines à excitation par aimants permanents, les aimants permanents (5) et pièces intercalaires (6) en métal amagnétique disposés sur le corps (3) du rotor sont retenus par une frette (7) située dans l'entrefer (9), laquelle est en matière plastique renforcée par fibres de résistance élevée. Lorsque la machine tourne, cette frette (7) s'élargit plus fortement que le corps (3) du rotor (1), même si elle est précontrainte, de telle façon qu'il peut y avoir des défauts d'équilibre. Pour maintenir le centrage, la surface externe (4) du corps de rotor (3) est subdivisée, selon l'invention, sur toute la longueur axiale par des évidements (11) et la rigidité d'extension du corps de rotor (3) en sens radial est adaptée, par des mesures de construction particulières, de manière approximative à la rigidité de la frette (7) avec les aimants permanents (5). Les évidements (11) forment des fentes (12) radialement extérieures et ont radialement à l'intérieur des extensions (14, 15) arrondies pour éviter l'effet d'entaille. Sur un rayon plus petit, on peut encore prévoir des évidements arrondis (16) supplémentaires. Un tel rotor d'une machine électrique à aimants permanents convient en particulier à des machines à grande vitesse de rotation.

Abstract: A multiple-stator synchronous induction motor which is started as an ordinary induction motor and then switched into synchronous operation when the rotational speed becomes close to the synchronous speed. The motor includes a plurality of stators (21, 22), an integrated rotor having rectifier circuits (33, 34) and rotor cores provided with rotor conductors (31, 32), static magnetic field generating devices (40) that generate static magnetic fields around the rotor cores, and voltage phase-shifting devices that generate voltage phase differences of 0° and 180° between the voltages induced at the rotor conductors. At the time of start, a circulating current flows between the rotor conductors with the voltage phase difference of 0°, so that the motor starts as an ordinary induction motor. During the steady-state operation, the voltage phase difference is switched to 180° and the static magnetic field generating devices are energized, whereby an alternating voltage induced by the static magnetic field is rectified through rectifying circuits, the direct current flows into the rotor conductors to form magnetic poles on the rotor cores, and the rotational speed is pulled into the synchronous operation owing to the attraction by the above magnetic poles and the rotary magnetic field established by the stators.

Abstract: Traitement d'états pathologiques chez un patient à l'aide de lipoprotéines oxydées, de préférence à l'aide de lipoprotéines peroxydées de faible densité. On décrit des procédés et un appareil de préparation des lipoprotéines oxydées. On découvert que les cellules malades, caractérisées par un nombre accru de récepteurs de lipoprotéines ou une capacité augmentée d'absorber des lipoprotéines sont plus sensibles que les cellules en bonne santé à l'effet cytotoxique de lipoprotéines oxydées. On utilise des lipoprotéines oxydées afin de traiter des états pathologiques tels que le cancer, le paludisme et les infections virales tels que le syndrome d'immunodéficience acquise (SIDA). On utilise la spectroscopie par RMN à protons et au carbone 13 afin de mesurer le degré et l'effet du traitement à l'aide des lipoprotéines oxydées.

Abstract: The invention relates to a construction device permitting assembly of a framing skeleton for targets, using modules. The module system used for manufacturing a framework for framing targets makes it possible to obtain a technique for changing the length of the frame, without any harmful effect on the quality of the assembly and makes it completely possible to construct archery targets of unlimited length. The object of the invention is also to facilitate implementation during installation on site. In fact, it is a simple question of fitting the "A" modules together and of fitting the "B" modules to the "A" modules at each end so as to construct a frame of any length. The modules are produced by means of elongate elements which are fixed together by means of sleeves, stiffeners and removable fixings (such as bolts). For every case, the frame thus produced serves to hold the material making it possible to stop the projectiles fired (such as arrows). <IMAGE>
