Abstract: La constatation et/ou le contrôle d'un niveau de remplissage prédéterminé d'un réservoir s'effectuent à l'aide d'un détecteur comprenant un système oscillant mécanique, un transducteur d'excitation électromécanique et un transducteur de réception électromécanique. Ce dernier est relié à l'entrée d'un circuit amplificateur à la sortie duquel est raccordé le transducteur d'excitation, de manière à amener le système oscillant mécanique à osciller, à sa fréquence de résonance propre. Le système oscillant mécanique est monté à la hauteur du niveau de remplissage prédéterminé, de manière à être en contact avec le produit contenu dans le réservoir, lorsque ce dernier a atteint ledit niveau de remplissage prédéterminé, ce qui entraîne une modification de la fréquence de résonance propre. Cette modification est déterminée par un circuit d'évaluation raccordé à la sortie du circuit amplificateur. Pour identifier des erreurs ne pouvant être détectées à partir de la grandeur de la fréquence mesurée, la connexion entre la sortie du circuit amplificateur et le transducteur d'excitation est interrompue momentanément pendant des intervalles de test prédéterminé et une comparaison des phases est effectuée à chaque intervalle de test, entre le signal de sortie du circuit amplificateur et un signal extrait du transducteur d'excitation.

Abstract: A frequency-selective optical switch capable of switching separate optical signals in a physical input channel to a selected output channel. A diffraction grating (12) spatially divides the input channel (10) into its frequency components, which pass through different segments of a liquid-crystal modulator (24). The liquid-crystal modulator segments (20, 22) are separately controlled to rotate the polarization of the frequency channel passing therethrough or to leave it intact. The channels then pass through a polarization-dispersive element (28) which spatially separates the beams (14, 16) in the transverse direction according to their polarization. A second diffraction grating (40) recombines the frequency components of the same polarization into multiple output beams (42, 44).

Abstract: The present invention discloses surface covering products and methods and an apparatus for making surface covering products. In particular, the method of the present invention includes depositing color particles on a moving carrier to form a base layer.   The base layer then comes in contact with a patterned embossing device such as a roll to create a depressed or displaced pattern image on the base layer.  Afterwards, accent particles or pellets are sprinkled or applied over the embossed base layer. The embossed base layer is subjected to heat and/or pressure to consolidate the accent and color particles and form a preformed mass. The preformed mass is then pressed to form a fused, texture-created structure. The surface covering products made from the process of the present invention have unique geometric patterns with well-defined grout lines or irregular decorative designs.

Title: Method of predicting body cell mass using bioimpedance analysis
Inventor: KOTLER DONALD P
IPC: A61B5/05
Filed: 1995-12-11
Granted: 2001-08-14
Abstract: Predictive equations for body cell mass (BCM), fat free mass (FFM), and total body water (TBW), were derived, using single frequency bioimpedance analysis (BIA). Preliminary studies demonstrated more accurate predictions of BCM when using parallel transformed values of reactance than the values reported by the bioimpedance analyzer. Modeling equations derived after logarithmic transformation of height, reactance and impedance were more accurate predictors than equations using height2/resistance, and the use of gender-specific equations further improved accuracy. The addition of weight to the modeling equation also improved accuracy but was less important than the impedance measurements. These results indicate that body composition can be estimated accurately using simple, inexpensive, and easily applied techniques, and that the estimates are sufficiently precise for use in clinical investigation and clinical practice.

Abstract: A process for the production of radiostrontium consists  in  that  a  target  of  metallic  rubidium  is bombarded by a flow of accelerating charged particles. The target of irradiated rubidium is melted, whereas the extraction of radiostrontium is carried out by sorption on the surface of a sorbing material immersed into the irradiated  molten  metallic  rubidium.  As  the  sorbing material,  use  is made  of materials  selected  from the group  consisting  of  heat-resistant  metals  or  metallic oxides  or  silicon  which  are  inert  with  respect  to rubidium. The resultant radiostrontium is extracted from the irradiated rubidium. The temperature of the sorbing material is selected to be close to the optimum one for the sorption of radiostrontium which is within the range of from the melting point of metallic rubidium to 220°C. And the temperature of molten rubidium is selected to be close  to  the  optimum  one  for  the  desorption  of radiostrontium within the range of from 220°C to 270°C.

Title: Circuit for causing fpll to lock in desired phase
Inventor: MYCYNEK VICTOR G
IPC: H03L7/087
Filed: 1997-08-12
Granted: 2000-10-17
Abstract: A biphase stable FPLL includes a lock switch, operated in response to a frequency lock condition, that forces a predetermined voltage on the input of the third multiplier to guarantee that the loop locks up in a phase that produces a desired polarity of demodulated signal.  A frequency lock indicator operates the lock switch to force the predetermined voltage on the third multiplier irrespective of the actual lock up phase of the loop.  If the lock up phase is wrong, the voltage reversal causes the VCO to slip 180° in phase and the loop locks up in its other bistable state.
