Patent EP-0404209-A1 (EP)
Inventor: HALL WILLIAM D
IPC: H05B6/06
Filed: 1986-04-29
Abstract: A ferromagnetic element (10) has current passed through it either by direct electrical connections or by induction. The current through the ferromagnetic element may be far greater than is necessary to heat the element above its effective Curie temperature. As the element is heated and is passing through its effective Curie transition (that is its temperature is rising from below its effective Curie temperature to, or above, its effective Curie temperature) the change in permeability of the element is sensed and the current through the element is cut off. The element then cools. When the temperature falls below the effective Curie temperature, the full current is restored. The heating and cooling process repeats itself indefinitely. The result is that the element is maintained at its effective Curie by a pulsating current fed to the element. The Curie transition may be sensed by directly sensing changes in permeability as by an auto-transformer winding (11), on the element (10); or by sensing changes in the power to the element by reason of the change in resistance of the element as it passes through the effective Curie temperature.

Abstract: A process for the preparation of optically pure diastereoisomers of tetrahydrofolate compounds is described, comprising the conversion, for example, of only the 5,6S,7,8-tetrahydrofolic acid component of a racemic mixture of 5,6,7,8-tetrahydrofolic acid to 10-formyl-5,6S,7,8-tetrahydrofolic acid in the presence of a formyl tetrahydrofolate synthetase, followed by cyclizing, hydrolyzing and derivatizing. The process is also useful to make a desired substantially pure (6R or 6S) enantiomer of a derivative or (radiolabeled) tetrahydrofolic acid or a salt or ester thereof.

Abstract: L'invention concerne un convertisseur logarithmique à étages multiples du type à "détection successive" ou "compression progressive" qui comprend des moyens assurant une fonction précise de transfert logarithmique à température stabilisée. Les étages de gain sont couplés par courant continu, bien que chacun d'eux utilise également un démodulateur comprenant un redresseur d'ondes pleines permettant le fonctionnement tant dans le mode de bande de base que dans le mode de démodulation. Le chemin du signal est différentiel et est équilibré, y compris les démodulateurs. Chaque étage de gain se base sur un amplificateur différentiel ou "une paire à queue longue" qui fonctionne dans un mode à boucle ouverte et est polarisé par un générateur de courant de queue qui envoie un courant de queue qui est à la fois proportionnel à la température absolue et est compensé automatiquement pour les effets de résistances finis de transistor beta et de base et d'émetteur. Les démodulateurs sont polarisés par une tension de décalage très faible qui est également proportionnelle à la température absolue. L'interception logarithmique est stabilisée en température soit en utilisant un atténuateur PTAT du système d'amplification complet soit en introduisant au niveau du noeud de sortie (une jonction d'addition de courant) un courant qui varie avec la température de manière à décaler le mouvement d'intersection qui, le cas échéant, serait généré.

Abstract: Une aube (20) de turbine composite présente une section aérodynamique monocristalline (22), une plate-forme monocristalline (26) et une section de fixation composite (24). La section de fixation (24) est constituée d'une fine couche (34) de matière monocristalline recouvrant et liée par procédé métallurgique le long de lignes de liaisons interfaciales (36) un noyau (30) constitué d'un superalliage polycristallin à grains fins. La couche (34) possède une configuration externe ayant des arêtes et rainures (28) pour permettre une fixation amovible dans une rainure complémentaire ménagée dans un disque d'une turbine. L'aube est préparée en coulant un corps monocristallin présentant une cavité dans la section de fixation (24), puis en remplissant la section de fixation avec un support superalliage polycristallin pour former une structure composite. Le remplissage s'effectue de préférence en vaporisant au plasma la cavité avec le superalliage, puis le superalliage atomisé subit un compactage isostatique pour réduire au minimum la porosité. La structure composite subit ensuite un traitement thermique pour développer une microstructure optimalisée dans la section de fixation à double alliage (24). L'aube (20) de turbine obtenue possède une longévité améliorée due à une moindre susceptibilité de la section de fixation composite (24) à la fatigue en cycle lent.

Abstract: The methacrylic ester polymers produced according to this invention are uniquely distinguished from the radically prepared polymers of similar composition by the fact that both polymers produced: by anionic living polymerization and by deactivating the active terminals of anionic living polymers; contain acetal and/or ketal groups as the blocked hydroxyl groups and have narrow molecular weight distribution. Hydroxyl group-containing methacrylic acid ester polymers are produced by hydrolysis of the above-mentioned polymers. The anionic living polymers are produced in high yields by anionically polymerizing methacrylic acid esters containing an acetal or ketal group in the presence of initiators such as alkaline metal alkoxides. The polymers of the present invention can be used in various fields of applications such as coatings and adhesives. The polymers of the present invention yield curable high solids compositions.

Abstract: Press, straight-slide piston press, large bale, tying device, needle, knitting principle, interrupt, protective device, wear reduction. The invention relates to a drive mechanism for tying devices on baling presses, especially such that a collision between the tying needle and press piston can be prevented. The aim is to prevent damage in the event of a sudden interruption of the drive, without any material-intensive oversizing of the needle-return device or any necessary combination of the piston stop and needle-return device. The object is to design the drive mechanism in such a way that there is no possibility of the needle rocker remaining stationary at top dead centre or in the immediate region of this, but overlock protection and a reliable functioning of the needle-return device are guaranteed. The object is achieved in that the driver (5) in the indexing wheel (1) is arranged pivotably in a bearing (4) and is held in the engagement region of the indexing pawl (8) by an overload protection means (6) attached in or outside the pivot axis, and in the event of an overload at top dead centre "T" of the tying needle (12) and in the immediate vicinity of this the driver (5) is positively guided by means of a roller (17) on a guide track (16) in engagement with the indexing pawl (8).
