Abstract: An electrically conductive cement which when used to bond electrically conductive mating surfaces provides substantially stable conductivity characteristics under high humidity conditions; comprised of a carrier that provides a volumetric shrinkage of more than about 6.8% (vol.) and a conductive filler including agglomerates, particles, powders, flakes, coated nickel particles, and coated glass spheres, having size and surface characteristics that maintain stable electrical contact by forming a moisture resistant contact with an electrical component lead. The carrier having a volumetric shrinkage between the uncured and cured states of greater than about 6.8% (vol) appears to effect a compaction of the filler particles causing the particles to be forced into enhanced electrical contact with the surfaces to be connected and to provide a measure of compaction between the particles themselves to enhance particle-to-particle conduction. The shrinkage of the polymeric carrier during curing places the interior particles under compression with sufficient force to urge the particles into engagement with one another as well as to cause the particles to penetrate non-conductive oxides that may be present on a component lead. <IMAGE>

Abstract: La présente invention concerne un procédé permettant de catalyser un dépôt de rapport pour mieux détecter ou quantifier un  élément d'analyse se trouvant dans un échantillon, par l'amplification du signal de détection. Le procédé consiste à immobiliser un système d'activation par enzyme dépendant de l'élément d'analyse qui catalyse le dépôt de rapport en activant un conjugué consistant en un substrat étiqueté de manière décelable et spécifique pour ledit système d'enzyme. Ledit conjugué réagit avec le système d'activation par enzyme dépendant de l'élément d'analyse pour former un conjugué activé qui se dépose sensiblement partout là où le récepteur pour le conjugué activé est immobilisé, ledit récepteur ne réagissant pas avec le système d'activation par enzyme. Dans un autre mode de réalisation, l'invention décrit un procédé d'analyse permettant de détecter ou de quantifier la présence ou l'absence d'un élément d'analyse dans un échantillon utilisant le dépôt de rapport par catalysation pour amplifier le signal de rapport. On décrit également des composés nouveaux que l'on peut utiliser comme agents de réaction pour préparer des conjugués de type HABA.

Abstract: Le procédé décrit, qui sert à la production de bouchons en caoutchouc pour fioles, se caractérise en ce qu'un film en résine synthétique est déposé en couche sur le côté des branches d'un bouchon en caoutchouc fourchu. Ce procédé de production comprend: (i) une première étape de formation qui consiste à superposer un film en résine synthétique (1) résistant aux médicaments ou aux substances chimiques médicales sur une feuille en caoutchouc non vulcanisée (2) puis à presser, chauffer et façonner conjointement ce film et cette feuille entre deux moules (A, B); une seconde étape de formation qui consiste à placer une feuille en caoutchouc non vulcanisée ayant sensiblement le même trou (10) que la partie de base de la partie des branches (4) de la pièce moulée primaire qui en résulte sur la pièce moulée primaire à partir du côté de ces branches, puis à presser, chauffer et façonner conjointement cette feuille et cette pièce moulée entre une paire de moules; et une étape de découpage et de retrait des bavures qui se sont formées autour de la pièce moulée secondaire produite. Ce procédé de production permet de mouler la partie de bouchon en caoutchouc et la partie de stratifié en résine synthétique en un seul procédé. En outre, étant donné que les étapes précitées peuvent être effectuées tandis que les matériaux utilisés sont maintenus en continu sous la forme de feuilles, ce procédé est particulièrement approprié pour la production d'un grand nombre de bouchons en caoutchouc pour fioles.

Abstract: It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to detect increases in transient D.C. current flowing in the respective phases of a distribution cable (10) feeding a transformer and also to detect increases in other selected functions of supply parameters for identifying and quantifying a fault current flowing in the distribution cable (10). Increases in these other functions are analysed to identify whether the increases indicate a fault current. Any such fault current can then be quantified and the triggering of a circuit breaker (19) initiated to isolate the supply cable on identifying a fault current. The circuit breaker (19) is not triggered for any increases in the other functions for as long as there is a detected increase in D.C. current in any phase.
