Patent EP-0216887-A1 (EP)
Inventor: MULLIN JOHN BRIAN THE HOO BROC
IPC: C07F3/06
Filed: 1986-04-09
Abstract: Un procédé de préparation de zinc diméthyle ou de cadmium diméthyle de pureté élevée approprié au dépôt de couches épitaxiales du groupe II-VI consiste à former un produit d'addition de l'alkyle métallique avec une amine tertiaire de non-chélation contenant au moins deux groupes amino tertiaires par molécule d'amine, et à dissocier ultérieurement le produit d'addition pour libérer l'alkyle métallique sous forme de vapeur. Les produits d'addition formés pendant le procédé de préparation se dissocient aisément en chauffant et cependant sont sensiblement involatils et par conséquent ne contaminent pas l'alkyle métallique libéré. Une amine préférée appropriée pour être utilisée dans le procédé de préparation est 4,4' bipyridyle.

Abstract: Des polyesters colorés insaturés contiennent certains colorants de méthine copolymérisés qui se condensent pendant la polymérisation dans la chaîne polyester. Les parties de colorant sont thermiquement stables aux températures de mise en oeuvre du polymère, ont des couleurs stables, et ne sont pas extractibles du polymère, ce qui rend ces polyesters insaturés colorés particulièrement indiqués pour la réticulation dans le moulage d'accessoires de salles de bains (éviers, douches, baignoires), bateaux, certaines applications automobiles, et similaires. L'addition de colorants au polyester de cette manière diminue les risques d'une non-uniformité du colorant comme c'est le cas lorsque le colorant est dispersé dans le mélange du polyester insaturé, de l'agent de réticulation, du catalyseur, etc., avant les opérations de coulage, moulage, et vulcanisation.

Abstract: The movement of an injector valve member (52) which closes and temporarily opens discharge orifices (58) communicating with the combustion chamber of an internal combustion engine is controlled by the fuel pressure in a control chamber (72) and by a difference in the pressure forces acting on a piston (60) having two sections (63, 69) with different diameters arranged at one end of the valve member (52). The pressure in the control chamber (72) to control the movement of the valve member (52) is controlled by means of two axially aligned orifices (67, 70) and by a solenoid valve (S) for closing and temporarily opening one of said orifices (70). A member (71) and the top end of the thicker section (69) of the piston (60) define said control chamber (72). Said thicker section (69) guides said member (71) at its inside, while the latter is not guided on its circumference 71b). The thinner section (63) of piston (60) is guided in the injector housing (44). The piston (60) is provided with a bore (65) connecting a chamber (46) communicating with the discharge orifices (58) across the other orifice (67) with the control chamber (72).

IPC: A61B5/1495

Abstract: An oximeter and method is disclosed for non-invasively measuring blood which is capable of determining the oxygen saturation of arterial blood. The oximeter includes at least one light source addressed to a tissue area of a patient, such as a finger or earlobe. A photodetector receives emitted light passing through the sample and a receiver circuit analyzes the data and produces an output which is proportional to the oxygen content of blood. The light source is driven at a preselected carrier frequency and the receiver circuit is tuned to said carrier frequency so that undesired signals can be filtered out leaving only the signals created by the emitted light passing through said tissue. The oxygen content is calculated using the patient's known red cell count, thereby correcting the final saturation value for patient anemia. Moreover, the calculation for oxygen saturation incorporates red cell scattering parameters for increased accuracy in clinical environments.

Une ou plusieurs bases de données (104) sont codées et enregistrées sur un dispositif (100) à mémoire rémanente de grande capacité (par exemple un disque optique). Un dispositif décodeur inviolable (310) et son contrôleur associé (316) décodent des parties seléctionnées de la base de données en mémoire (104) et mesurent la quantité d'information décodée. L'information concernant cette quantité mesurée est transmise à une installation centralisée de facturation à distance et utilisée pour taxer l'utilisateur en fonction de son utilisation de la base de données. Le système (10) peut comprendre une fonction d'auto-destruction qui invalide le fonctionnement du système en l'occurrence d'un événement prédéterminé, à moins que l'utilisateur applique un ''antidote'' - et les instructions d'application de l'antidote ne lui sont données par le propriétaire de la base de données que s'il a réglé sa facture. On obtient ainsi une sécurité absolue de la base de données et une facturation en fonction de l'utilisation dans un type de système où toutes les tâches d'accès à la base de données sont exécutées chez l'utilisateur. En outre, l'invention assure un environnement compétitif caractéristique d'un marché libre, étant donné que des droits d'auteur sur la propriété littéraire peuvent être calculés en fonction de l'utilisation réelle des données.

Abstract: A shock absorber useful in motor vehicles which includes a piston inside of which an entire quantity of a damping fluid exchanged between two work chambers flows via a throttle cross section the size of which is defined by an electromagnetic adjusting device comprising primarily a magnet coil and an armature. The armature is annular and merges with an annular control slide provided with a slide control edge, which slide, in cooperation with a piston control edge on the piston determines the size of the throttle cross section. The control slide and armature are statically in pressure equilibrium, and because of their annular embodiment they have only a slight weight of their own, so that the shock absorber operates with short adjusting times. By way of a defined profile of the slide control edge or piston control edge, certain damping characteristics are attainable.

Abstract: A process and a device for measuring the phase of arbitrary signals at a test point, for example of surface waves on piezoelectric substrates, in which surface waves are excited on the surface of a specimen exhibiting piezoelectric properties. A test point on the specimen surface is scanned with the aid of a particle beam (PE) by a stroboscopic method and at the test point of the specimen surface in which the beam is applied in each case, a secondary electrical signal (SE) is supplied to an evaluating circuit (AS) via a detector (DT). The phase detector (PD) in the evaluating circuit (AS) is operated in a linear range of its output characteristic with the aid of a feedback (RK). This makes it possible to keep the phase constant at the phase detector. It is either the phase of the particle beam (PE) or of the signal to be examined, for example the surface wave which is generated at the inter-digital converter (IDW), which is influenced by the feedback (RK). <IMAGE>

Abstract: Provision is made here to form the submersible body (1) as a receiving vessel by means of an envelope of flexible material and to arrange it between a dimensionally stable bow and stern element (5 and 6). Here, water-inlet openings (11) are arranged in the bow area so that a dynamic pressure of the trapped water arises due to the closed stern area. The flexible body thereby acquires a rigid configuration which serves to produce pressure zones of real ships/submarines. Furthermore, the type of construction of the envelope ensures that magnetic ship zones are produced and enables noise generators (10) to be fitted. <IMAGE>
