Abstract: A solid state switch (10) is provided which has the capability of retaining its last state memory in the event of a power failure or interruption. The solid state switch includes an output driver formed of at least one N-channel MOS field-effect transistor (N1), a holding capacitor (C1), a charging resistor (R1), a transistor-connected diode (D1) interconnected between a power supply voltage source (Vcc) and the charging resistor (R1) for preventing leakage of the holding capacitor (C1). The field-effect transistor (N1) has its drain connected to a first output terminal (14) and its source connected to a second output terminal (16). One end of the holding capacitor (C1) is connected to the gate of the field-effect transistor (N1) and its other end is connected to a ground potential. The holding capacitor (C1) retains the last state between the first and second output terminals (14,16) in the event of a loss of the power supply voltage source (Vcc).

Abstract: The present invention relates to a supporting elbow (12) for a sun vizor (1) supplied with electricity by at least two conductors (5, 6) running inside the said supporting elbow (12). The said supporting elbow (12) is made by over-moulding at least one portion (5c, 6c) of the said conductors (5, 6) with a plastic material in such a way that the said conductors form a block with this plastic material. According to the method of the invention, the over-moulding is carried out in two steps: a first step in which the said portion of conductors is over-moulded with plastic material in such a way as to obtain a supporting elbow blank (22) of which at least one part has a cross-section less than the corresponding cross-section of the said supporting elbow, and a second step in which the said blank is over-moulded in order to obtain the said supporting elbow in a finished state. …<IMAGE>…

IPC: F01C19/00
Filed: 1991-12-02
Abstract: The sealing between two machine parts has on one of the mutually facing surfaces (5), forming the sealing gap, a layer of plastic (1) with reinforcements (8) provided in close arrangement next to one another, which reinforcements have the form of partially cut-off bubbles of a foam plastic structure. They were created by removal of a layer of plastic (3) foamed onto the machine part, the layer thickness having been reduced evenly to such an extent that the bubbles (4) of the lowermost bubble layer (4), adjacent to the base surface (5) of the machine part (2), are opened. It is achieved in this way that the insulating effect of closed bubbles of a layer of foam plastic is avoided and that the layer of plastic has a very low weight, by which the risk of any detachment of the layer by centrifugal forces is avoided. In addition, a honeycomb-like open surface structure is achieved in a simple way, so that a labyrinth effect is obtained in the sealing gap. To achieve minimal sealing gaps by contracting, the open, honeycomb-like surface structure is particularly advantageous, since the contact occurring thereby, which is only linear, ensures a rapid contracting on the counter surface, which may be abrasively prepared. The sealing is suitable in particular for very quickly rotating machine parts. …<IMAGE>…

Title: Acide biliaire conjugue synthetique et procede d'utilisation de ce dernier
Inventor: HOFMANN ALAN F
IPC: A61K31/575
Filed: 1991-03-13
Abstract: L'invention concerne un procédé pour remplacer l'acide biliaire normalement présent dans les voies biliaires, lorsqu'il se produit une insuffisance de cet acide biliaire. Le procédé consiste à administrer une quantité efficace d'un acide biliaire synthétique renfermant le produit de réaction d'un acide biliaire naturel et d'un acide aminé N-alkyle. L'élément primordial de cette invention réside dans la présence d'un acide aminé N-méthyle en tant que fraction de molécule de conjugaison pour l'acide biliaire synthétique. Ce phénomène n'existe pas dans la nature et c'est un facteur clé de l'efficacité des composés ci-décrits dans la méthode de traitement de l'invention. Une composition de remplacement de l'acide biliaire fait également partie de l'invention, elle comprend le produit de réaction d'un acide biliaire naturel et d'un acide aminé N-alkyle. Cet acide aminé N-alkyle est une N-alkyle glycine, préferablement une N-méthyle glycine; l'acide biliaire naturel est l'acide cholique; et dans la version servant d'exemple, le composé est le produit de réaction entre la N-métyle glycine et l'acide cholique, c'est-à-dire la cholysarcosine. Des utilisations potentielles de ces composés au niveau clinique en tant que composés de remplacement de l'acide biliaire naturel comprennent l'utilisation des composés de ce type lorsqu'il se produit une baisse de la sécrétion d'acide biliaire dans l'intestin grêle ou lorsque les acides biliaires sécrétés normalement sont déconjugués par une surcroissance bactérienne.

Abstract: Un appareil destiné à effectuer des opérations d'entrée/sortie (E/S) dans un système informatique fonctionnant sous la commande d'un système UNIXXT comprend un ordinateur de traitement de communication spécialisé en plus de l'ordinateur central. Ces deux ordinateurs centraux communiquent par l'intermédiaire d'une mémoire partagée à laquelle chaque ordinateur a accès indépendamment. Les fonctions exécutées par le module de gestion d'E/S du terminal et les modules de gestion de lignes sont divisées entre l'ordinateur central et l'ordinateur de traitement de communication. L'ordinateur de traitement de communication effectue tous les traitement canoniques des données reçues des dispositifs d'E/S du terminal. Il entretient également une structure de données indiquant l'état instantanné de chaque dispositif d'E/S du terminal. Grâce à cette structure de données, l'ordinateur de traitement de communication peut fonctionner dans un environnement sensiblement exempt d'interruption, n'interrogeant que les dispositifs d'E/S qui sont indiqués, dans la structure de données d'état, comme nécessitant une prise en charge. Une fonction message dans la mémoire partagée gère les communications entre les ordinateurs. Chaque ordinateur envoie des messages à l'autre par l'intermédiaire d'une file d'attente circulaire spécialisée. Afin de recevoir un message, un ordinateur examine la file d'attente d'envoi de l'autre ordinateur. Des messages de réponse sont renvoyés à l'ordinateur d'envoi à l'aide du même tampon de message que celui utilisé dans le message original.

Abstract: A circuit arrangement is specified for the production of an alternating voltage in an electronic apparatus which is connected via a remote supply (ASL) to a DC voltage. Arranged in the apparatus are a power supply section (2) and a clock transmitter (4) whose pulses are supplied via a control element to the control electrode of a first transistor (T1). Located in the current path of the first transistor is the primary winding (6), which is connected to the DC voltage, of a transformer to whose secondary winding (7) at least one external load (RL) is connected which is equipped with a coupling capacitor (CK). A second transistor (T2), whose control electrode is likewise connected to the control element, is connected with its current path in series with the secondary winding (7) of the transformer. The control element has a logic unit allocated to it by means of which only one of the two transistors is always selectively connected to the clock transmitter (9). The coupling capacitor is thus alternately charged and discharged again. <IMAGE>
