Patent EP-0419753-A1 (EP)
Inventor: GULMINI CARLO
IPC: H05G1/46
Filed: 1989-09-28
Abstract: The identification system essentially consists of an emission source (1) of electromagnetic waves which are sent towards a receiver-sensor (2) fitted at a distance determined in advance. In absence of an interposed body the energy level reaching the receiver-sensor (2) is the reference measurement. Owing to the interposition between the emission source (1) and the receiver-sensor (2) of a plastic material body (3), such as polypropylene, polythene, polystyrene, vinyl chloride resin and others, a specific and charateristic modification is obtained of the energy level that can be observed for each type ofr different interposed plastic material, by reading the voltage level supplied by the receiver-sensor (2).

Title: Method for producing hall effect sensor for magnetic recording head
Inventor: MALLARY MICHAEL
IPC: H01L43/14
Filed: 1988-11-25
Abstract: A method of forming a Hall effect sensor for a magnetic recording head including the steps of providing a single 
crystal substrate having a chemically dissimilar single crystal film thereon, providing a ceramic substrate having a first 
magnetic pole piece of a selected thickness formed on a surface thereof, positioning the single crystal substrate and the cer­
amic substrate with the single crystal film and magnetic pole piece surfaces in an opposing relationship, bonding the posi­
tioned ceramic substrate to the single crystal film on the positioned single crystal substrate to form a laminated structure 
having a substantially thin uniform bond line, removing chemically the single crystal substrate from the single crystal film, 
forming a Hall effect pattern in the film while one surface of the film is exposed, and depositing a second magnetic pole 
piece on the formed Hall effect pattern.

IPC: A47J43/26

Abstract: Avec les casse-noix habituels, on endommage souvent non seulement la coque mais encore la noix en cassant la coque pour l'ouvrir parce que la force est appliquée de manière non contrôlable et que les leviers du casse-noix sont pressés l'un contre l'autre d'un coup. Pour les grosses noix en particulier, la main n'est souvent pas assez large pour tenir les deux leviers et l'importance de la force requise, pour les noix dures particulièrement, peut avoir des effets désagréables sur le poignet. En séparant la mâchoire (1) du casse-noix du levier (3), on obtient une trajectoire maximale du levier constante et indépendante du diamètre des noix. Simultanément, en munissant la mâchoire (1) du casse-noix d'une couronne dentée, on limite le mouvement des leviers du casse-noix. Lorsque l'on répète le mouvement de tenaille des leviers (2) et (3), la mâchoire (1) se rapproche cran par cran de la noix. On ne casse ainsi que la coque, sans endommager la noix. De plus, la force requise est sensiblement réduite.

Abstract: Cette invention concerne un procédé simple permettant la production d'oxime anhydre par la séparation de l'oxime d'une solution aqueuse. Le procédé présente l'avantage d'éliminer les dangers d'explosion inhérents aux procédés actuels, et de séparer facilement l'oxime de la phase aqueuse. Ledit procédé comprend les étapes consistant à (a) vaporiser une solution d'oxime aqueuse; (b) à vaporiser un solvant organique de l'oxime, non miscible à l'eau, le point d'ébullition dudit solvant étant inférieur au point d'ébullition de l'oxime; (c) combiner les vapeurs; (d) condenser les vapeurs collectées; (e) éliminer de la phase aqueuse la phase organique du condensat; (f) récupérer l'oxime anhydre de la phase organique éliminée. L'oxime anhydre produite selon le présent procédé est utile dans des applications telles que la condensation d'isocyanate et la formation de carbamate.

Abstract: La présente invention se rapporte à une nouvelle plaque porte-échantillons (10) pourvue de plusieurs cuvettes à échantillons (11) et servant pour des tests de liaison radiomarqués. Une partie substantielle des cuvettes à échantillons (11) de la plaque porte-échanitillons (10) est produite par scintillateur plastique. Les surfaces internes des cuvettes à échantillons (11) sont recouvertes d'un composé de liaison (12) qui se lient spécifiquement au réactif radiomarqué qui est en cours d'examen et qui se trouvent sous la forme d'une solution dans les cuvettes à échantillons (11). La partie du réactif radiomarqué qui se lie à la surface du composé de liaison (12) est suffisamment proche des parois des cuvettes à échantillons (11), de sorte que le rayonnement émis par le réactif radiomarqué lié peut agir en interaction avec le matériau de scintillation des parois des cuvettes à échantillons (11). Il résulte de cette interaction qu'une partie de l'énergie du rayonnement est convertie en lumière, laquelle peut être mesurée par un appareil approprié n'entrant dans le domaine traité par les pièces descriptives de cette invention.

Abstract: Die Erfindung betrifft ein Verfahren zum thermischen Oberflächenhärten von metallenen Werkstücken, insbesondere von Wellenenden, mittels einer Laserquelle, bei dem ggf. unter Relativbewegung von Werkstück und Laserquelle, die zu härtende Werkstückoberfläche bereichsweise durch Laserstrahlung erwärmt wird. Erfindungsgemäß wird die Laserstrahlung im wesentlichen gleichmäßig in einer Härtezone eingestrahlt, die sich in einer Hauptrichtung wenigstens annähernd über die gesamte zu härtende Werkstückoberfläche erstreckt. Weiterhin betrifft die Erfindung eine Einrichtung zum thermischen Oberflächenhärten von metallenen Werkstücken, insbesondere von Wellenenden, mit einer Laserquelle zur Abgabe von Laserstrahlung auf die zu härtende Werkstückoberfläche und ggf. mit Einrichtungen zur Relativbewegung von Laserquelle und Werkstück; erfindungsgemäß vorgesehene Spiegeleinrichtungen formen die von Laserquelle abgegebene Laserstrahlung zu einem flächigen Strahl um und richten diesen auf eine Härtezone, die sich in einer Hauptrichtung wenigstens annähernd über die gesamte zu härtende Werkstückoberfläche erstreckt. So wird eine wesentlich homogenere Erwärmung der Werkstückoberfläche erreicht, die Härteschwankungen aufgrund übermäßiger oder mangelnder Aufhärtung ausschließt.

Abstract: In the process of fixing a metal screen in the housing of a vacuum switch, the screen is plastically deformed radially outwards over an internal supporting edge in the housing. The plastic deformation of the screen is carried out at an edge thereof, in such a way that an outward flanged edge is formed. Thus, the screen is retained on the supporting edge by that flanged edge and a part of the housing with a relatively large diameter. Therefore, the screen has a part with a relatively small diameter which is essentially equal to the internal diameter of the supporting edge of the housing.

Abstract: This clamp is intended for butt welding two tubes disposed along an axis (3), by means of an electrode (14) given a circular movement (18). Two rings (1, 2), which are mounted so as to rotate about the axis (3), are rotatably driven by means of pinions (7, 8, 10, 11). A swinging member (13) serving as support to the welding electrode (14) is pivotally mounted to a ring (1). A cam (16), which interacts with an element (15) integral with the swinging member (13), is provided on the other ring (2). The two rings (1, 2) are driven by separate motors with which are associated drive and control means enabling the speed of rotation of at least one of the rings to be modified in such a way as to vary the distance between the electrode (14) and the shaft (3). The height of the arc is thus adjusted.

Abstract: The mechanism of the subject invention provides for an efficient interface between the hardware parts and software parts of communication modules used in a communication node wherein one module communicates with another module through a very high speed communication media. It insures the integrity of the data messages transferred between modules without impairing the performance of the data transfers. 
     To deal with the problem of data message integrity at a very high speed, data link control DLC protocol relevant to steady state functions is implemented in hardware by finite state machines in the data store interfaces 14 and software running in microprocessor 16 is in charge of the initialization and recovery procedures.The steady functions are implemented by the hardware using sets of indicators in a request table which are representative of the transfer conditions, control blocks SCB which are representative of the transmission protocol variables and a message parameter/status field to carry the xmission protocol variables relevant to the message to the destination node. If an error is detected by the hardware part the indicators allows to freeze the operations of the hardware in order the microprocessor performs the error recovery functions using the transmission protocol variables in the control blocks.
