Abstract: Dans les embrayages à friction connus dont les disques, déplaçables axialement et reliés en alternance de manière solidaire en rotation à une entrée d'embrayage et à une sortie d'embrayage qui lui est concentrique, sont amenés en contact de friction aux fins d'accouplement par une plaque de pression axialement déplaçable ainsi que par deux segments de pression disposés en ligne par rapport aux disques et pourvus respectivement de régions de surface correspondantes inclinées axialement en forme de rampe, la course utile d'embrayage est fonction du nombre total des disques; elle s'allonge en conséquence en cas d'usure des garnitures de friction. Ce nouvel embrayage à friction présente une faible course utile largement indépendante de l'usure, et cela indépendamment du nombre total des disques. Les deux segments de pression (6, 7) sont agencés entre la plaque de pression (5) et les disques proprement dits (3, 4).

Abstract: The spectra of voiced sounds lie predominantly at or below about 1 kHz. The spectra of unvoiced sounds lie predominantly at or above about 2 kHz. It is known to determine the lower- and higher-frequency energy components contained in a sound or sound element, to compare these energy components, and to use the result of the comparison to make a voiced-unvoiced decision. Since the distributions relative to voiced and unvoiced segments are overlapped, false decisions are liable to occur. The invention is predicated on the fact that a change from a voiced sound to an unvoiced sound or vice versa always produces a clear shift of the spectrum, and that without such a change, there is no such clear shift. From the lower-and higher-frequency energy components, a measure of the location of the spectral centroid is derived which is used for a first decision. Based on the difference between two successive measures, a second decision is made by which the first can be corrected.

Abstract: Disclosed are polymeric materials comprising an interpenetrating network (IPN) prepared from allyl polymers and epoxy resins. The allyl polymers are crosslinked under the influence of a radical initiator, the epoxy resin is crosslinked by a curing agent. The curing agent is a cyclic anhydride containing a polymerizable double bond. The two networks are interlinked as a result of the double bond being involved in the curing reaction of the allyl polymers. The cyclic anhydride preferably is maleic anhydride. Preferred IPN's are prepared from triallylcyanurate or triallylisocyanurate-based allyl polymers and phenol-type epoxy resin.

Abstract: Systems for interchanging information, for example, obtaining cash from a terminal by use of a portable device such as a credit card are well-known but suffer from being vulnerable to fraud. In the invention a highly secure information interchange system is achieved by utilizing an intelligent card (4) as the portable device which verifies that the terminal (3) is a valid one and the terminal in turn verifies that the card is valid. Unauthorized users are screened out by means of a physical characteristic scan of the user such as a finger print which is then compared with comparable data stored on the portable device (4). If an invalid terminal (3) attempts to communicate with the card (4), the card (4) erases the data and program from its memory. All programs and data in the terminal (3) are stored in memory which loses its contents when power is interrupted, thus improving the security of the system by making unauthorized use of a terminal very difficult. The terminal can only be brought back up by authorized personnel with their own access portable devices. Both a system and a method are claimed.

Abstract: Une fois que l'on a foré un nouveau puits de pétrole et qu'on l'a revêtu, on met en place une rame d'essai pour évaluer le potentiel de production de la formation choisie. L'une des façons de commander le fonctionnement des divers outils compris dans la rame d'essai du fond, comprenant aussi l'ouverture et la fermeture de la vanne de fond elle-même, consiste à utiliser les variations de différentiels de pression entre la colonne et l'espace annulaire l'entourant dans le puits, mais cela nécessite la présence et le maintien d'une pression 'de référence' prédéterminée dans l'outil, une telle pression appropriée étant la pression hydrostatique (annulaire) exercée sur la rame après qu'elle ait été descendue dans le forage et mise dans la garniture d'étanchéité. L'invention propose de piéger la pression de référence se trouvant dans la rame de test par un mécanisme nouveau, où une vanne (4), que l'on peut mettre en position fermée par le biais d'un premier piston (3) ouvert (en 5) à la pression annulaire, définit d'abord, puis définit et ferme, l'entrée ouverte à la pression de la colonne (6) donnant sur un passage (30,19) qui mène à une chambre contenant un gaz de référence (22) par le biais d'un second piston (20) qui s'y trouve. L'invention décrit également un mécanisme nouveau, par lequel on peut compenser les effets qu'ont les changements de température au fond sur le gaz dans une chambre de pression de référence, et dans lequel une chambre contenant un liquide hydraulique (27) est connectée à l'un des bouts, par un piston (25) qui y est monté, à un trou d'aérage (24) et à l'autre bout à deux passages 'à sens unique' (28, 29) qui la relient à la chambre contenant du gaz de référence (22) par le biais d'un second piston (23) contenu dans la chambre.

Date Dec. 13, 1990.The removal of sulphides from gas streams while using a solid absorbent containing tin, tin oxides or mixtures thereof and optionally a stabilizing component consisting of nickel, copper, cobalt, iron or oxides thereof takes place by contacting the sulphide-containing gas stream with the solid absorbent, which is expediently in the form of a carrier with the tin component and the stabilizing component; hereby the absorbent is sulphided and the gas stream desulphided. Subsequently the sulphided absorbents are regenerated by being contacted with a stream of steam. The regeneration process employed is substantially thermoneutral so that superheating and consequent sintering of the absorbent is avoided; moreover it is not necessary to operate at low temperatures, whereby the formation of sulphates as a by-product is avoided.

Abstract: For coating planar substrates, for example the interior or exterior surfaces of buildings, a substrate (10), which is as flat as possible, is coated with an adhesive layer (12) which supports a planar carrier (16). According to the invention, this is a thin, flat material having in its depth dimension a zone of which the material strength is less than the adhesive strength with respect to the substrate. It is preferred to use a porous, impregnated long-fibre paper, having a thickness in the range of 0.30 to 3.00 mm, especially 0.50 to 0.80 mm, and having a basis weight not below 130 g/m<2>, particularly of bleached cellulose fibres having a length of 2 to 5 mm and a fibre thickness of 10 to 50  mu m. A capillary width in the range of 50 to 150  mu m is also favourable for impregnation with acrylate resin and/or a fungicide. The adhesive layer is a high-viscosity, humidity-insensitive adhesive, for example a pasty, rollable dispersion adhesive made of polyvinyl acetate or acrylate. The carrier (16) adhering to the substrate can simultaneously be an insulating material and can be externally coated, for example with a coat of paint or plaster (22). <IMAGE>

Abstract: Immunologically active peptides or polypeptides with a partial amino acid sequence of the capside protein VP1 and VP2 of parvovirus B19 are obtained which provide an economical, sensitive and specific test to detect antibodies against the human parvovirus B19. Short peptide sequences are identified which when used as an antigen serve to identify anti-B19 IgG-positive sera. The production of these peptides by gene-technological means is revealed. Other gene-technologically produced antigens which form stably in large quantities in E. Coli and can subsequently be separated from them act as additional antigens for IgG confirmation. Finally a set of antigens facilitates testing for the detection of IgM antibodies against the virus. In addition, the gene-technologically produced components of the surface proteins are substances which may be used for prophylactic immunisation.

Abstract: Un modulateur Fabry-Perot (FP) asymétrique comprend une structurede puits quantiques présentant des puits plus larges (environ 150Å) que les puits normaux (environ 100Å). La cavité FP présente une résonance à une longueur d'onde d'une crête d'absorption excitonique maximum de la structure de puits quantiques. Bien que la modification maximale de l'absorption sous la polarisation appliquée soit moins grande dans les puits de 150Å que dans les puits de 100Å, les caractéristiques de l'électroabsorption se modifient également, ce qui fait que la modification la plus grande se produit à la longueur d'onde de l'excition el-hhl de la limite de bande sous une polarisation nulle. On peut réduire l'absorption en polarisant le puits quantique, et ledit modulateur FP peut donc présenter la caractéristique d'être normalement au repos (polarisation nulle, réflectivité nulle). Un tel agencement rend possible une modulation à contraste plus élevé et/ou des tensions de fonctionnement moins hautes. Le modulateur FP peut s'utiliser dans les dispositifs à effet électro-optique (SEED).
