Abstract: L'invention concerne un procédé pour déterminer la charge longitudinale s'exercant sur des supports soumis à des contraintes longitudinales, notamment des rails de chemins de fer, en particulier pour déterminer la température neutre de ces derniers. Le support est excité dans le sens longitudinal dans une plage de fréquences acoustiques, et la valeur du bruit magnétique de Barkhausen au niveau de la surface de la région excitée est mesurée; des mesures du bruit magnétique de Barkhausen sont effectuées pour différents états de contrainte longitudinale et utilisées pour tracer la courbe d'étalonnage du bruit magnétique de Barkhausen en fonction de la contrainte longitudinale, le bruit de Barkhausen étant mesuré en au moins trois points sur la face du support intégré, et la courbe d'étalonnage sert à déterminer la charge longitudinale sur la section transversale en question à l'aide du calcul de la moyenne, pondérée s'il y a lieu. La température neutre est ensuite déterminée le cas échéant sur la base de la charge longitudinale et compte-tenu du module d'élasticité, du coefficient de dilatation et de la température du rail. L'invention concerne également un dispositif pour déterminer la charge longitudinale exercée sur des supports soumis à des sollicitations longitudinales, notamment des rails, en particulier pour déterminer la température neutre de ces derniers. Ce dispositif comporte une unité d'excitation à fréquences acoustiques, un capteur magnétique qui est amené en contact magnétique avec le support, une unité de mesure sélective de fréquence reliée au capteur magnétique et sensible aux fréquences supérieures à celle de l'unité d'excitation, et un processeur qui calcule les résultats de mesure sur la base des valeurs mesurées. Une jauge d'entrefer (403) déterminant l'écart entre le capteur (404) et la surface du support est adjointe au capteur magnétique. Cette jauge est reliée à l'entrée du processeur (406), laquelle ajuste la valeur mesurée du bruit de Barkhausen en fonction de l'entrefer.

Title: Multilayer thin film bandpass filter
Inventor: CUSHING DAVID HENRY
IPC: G02B5/28
Filed: 1998-09-03
Abstract: A novel design for producing band pass filters with essentially square shapes with little or no ripple in the passband zone. Filters are of the all-dielectric type consist of multiple cavities of band passes. Quarter wave thick layers of low index material separate all of the cavities from each other. Multiple half-waves may be added to the outer cavity quarter-wave stacks in particular. This invention provides the addition of half wave to some of the inner cavity stacks to remove ripple that would otherwise be present. Together, these additional half wave layers added to the outer and inner cavities sharpen the transition from low transmission to high transmission without unduly adding ripple to the high transmission zone.

Title: Radio receiver for digital audio broadcasts including messages as well as radio programs
Inventor: SCHEPERS HEINER
IPC: H04H20/59
Filed: 1998-10-26
Abstract: The radio receiver (100) for digital radio broadcasts containing different message signal types has a loudspeaker output (16) and a message filter device (28) that passes or conveys only certain predetermined types of message signals to the loudspeaker output and interrupts a current state of the radio receiver (100) to make the preselected messages audible but suppresses the remaining types of message signals so that the current state of the radio receiver is not influenced by those latter signals. The message filter device has different states. These states in a preferred embodiment are designated only, for example, with "OFF", "ON" and "PS". "ON" means that the special message having this attribute is conveyed to the loudspeaker output through the filter device, i.e. the filter device is in the active state. "PS" expands the filter action, since only those programs are selected which contain message signals having this attribute when the program is changed, i.e. when the receiver is tuned to a new program. "OFF" indicates the state of the filter device is not active for message signals having this attribute, i.e. messages of this type are ignored and not passed through the filter device.

IPC: B65D75/58
Filed: 1998-10-28
Abstract: An easy-open and tamper-evident beverage container and opening system for the beverage container are provided which include a container barrier wall.  The barrier wall has a series of slits therein which define a pierceable straw hole.  The series of slits divides the barrier wall into a hole portion and a remainder portion, with the hole portion connected to the remainder portion by attachment points provided between adjacent slits of the series.  A membrane seal is located inside of the container and sealingly covers the straw hole.  This membrane seal is liquid impervious and includes (a) an outer portion which is sealed to an inside surface of the front barrier wall about the straw hole, and (b) an inner portion integral with the outer portion which is not sealed to the inside surface of the barrier wall and which covers the straw hole.  With this construction, when piercing the container with the straw, the straw breaks at least some of the attachment points as the straw pushes on the hole portion and as the straw then easily pierces the membrane seal.  The breakage of the attachment points thus provides readily observable and unrepairable evidence of opening of the straw hole. Preferably, the series of slits form a circular straw hole and the membrane seal is circular and centered about the straw hole.

Abstract: An oxygen sensor is disposed behind an exhaust gas purifying catalyst for an internal combustion engine and which suppresses the influence of unburnt hydrocarbon on the output voltage. A sensor element 1 is provided with a detection electrode 4 on the outer face of a zirconia ceramic body 2, a reference electrode 3 on the inner face of the ceramic body 2 and a spinel protective layer 5 on the outer surface of the detection electrode 4. The tip end of the sensor element 1 is covered with a protective cover 10 which is provided with an outer partition wall 11 having through holes 11a and an inner partition wall 12 having through holes 12a.      In a case where the pressure difference between the inside and outside of the protective cover 10 is .DELTA.P(atm) when the atmospheric air with a volume flow rate Q(1/min) is passed into the protective cover 10 from the outside, the ratio .DELTA.P/Q2 is 3.2×10 -5(atm.cndot.min2.cndot.1 -2).  When the surface temperature of the sensor element 1 is changed in a range of sensor active temperature, the reversing time is substantially constant. Therefore, the catalyst deterioration can be detected by the oxygen sensor with high accuracy.
