Abstract: On a mis au point une carte de paiement portative contenant un circuit de mémorisation pouvant être réécrit, conçu pour mémoriser une représentation d'une valeur monétaire (un "crédit"). Ladite représentation se présente sous une forme complémentaire chiffrée, représentant la différence entre le chiffre le plus élevépouvant être représenté dans une mémoire donnée et la valeur que l'on veut en fait représenter. Ladite carte est conçue pour accepter l'entrée d'un second chiffre, qui est représenté sous forme arithmétique normale et consitute la valeur en espèces d'une "imputation" que l'on veut appliquer au crédit stocké précité. On procède à ladite "imputation" en faisant une addition arithmétique normale à la valeur mémorisée, et audit chiffre d'"imputation". L'apparition d'un "report" à la fin d'une telle addition (signifiant que la somme finale est trop élevée pour être mémorisée dans la mémoire disponible) sert à indiquer une imputation non valable, ledit "report" servant à la fois à empêcher une éventuelle altération de ladite valeur de crédit mémorisée, et à indiquer à un autre moyen d'affichage associé que la transaction demandée ne peut être exécutée.

Abstract: Dans la sonde à charnières décrite, plusieurs plaques (4, 10, 45, 46, 47) sont empilées dans la direction de l'axe (11) de la sonde. Les plaques sont reliées entre elles par paires au moyen de charnières (12, 50, 52 et 53) (dont diverses formes sont décrites), qui définissent des axes de pivot et qui obligent chaque paire de plaques à effectuer un mouvement pivotant relatif autour d'un bord latéral de la paire. Les axes de pivot sont placés perpendiculaires les uns aux autres pour permettre l'inclinaison d'un palpeur (2) (fixé à l'une des plaques (4)) dans n'importe quelle direction grâce au mouvement pivotant de l'une au moins des plaques, lors de l'application d'une force sur le palpeur. Une position de repos axiale pour chaque plaque mobile située sur une plaque adjacente est définie en combinaison avec la charnière par un support supplémentaire (4, 16) disposé entre chaque paire de plaques sur le côté de l'axe (11) de la sonde opposé à l'axe de pivot respectif. Un ressort (17) maintient les plaques dans leurs positions de repos respectives. Tout mouvement transversal relatif des plaques d'une paire est empêché grâce à un ressort plan (20) (ou autres dispositifs) (en plus de la charnière éventuelle). La charnière peut ainsi être conçue entièrement flexible, assurant alors au palpeur une position de repos précise dans laquelle il retourne, lorsque l'application d'une force d'inclinaison est interrompue, et la force nécessaire pour retirer le palpeur de sa position de repos est réduite au minimum.

Abstract: Un circuit d'élimination de signaux transitoires (11, 14) disposé dans une boucle de communication locale s'étendant d'un téléphone d'abonné (15) à un central téléphonique (12) effectue le couplage de signaux de sonnerie et d'état raccroché/décroché au travers de la boucle après élimination des signaux transitoires dans ces signaux. Le réseau de circuit isole également l'abonné et le central de la boucle locale jusqu'à ce qu'un signal d'état décroché soit détecté et rétablit cet isolement lorsqu'un état raccroché existe au niveau du téléphone de l'abonné. De cette manière, la boucle locale peut être utilisée simultanément à la fois pour des communications vocales et un second signal d'information, chaque signal étant capable d'occuper la même largeur de bande. Ces signaux peuvent fonctionner indépendamment l'un de l'autre.

Abstract: In an arrangement for carrying out the method, a first sensor (1) a second (2), a computer (3) and a display (4) are present, which together form a measuring arrangement (5) for measuring the physical quantity (x), which is a distance (L), for example, which is present between a front surface (7) of a moving body (6) and front surface of the first sensor (1). The moving body (6) has, e.g., a mechanical stop (8). The computer (3) serves to evaluate output characteristics (f[x],g[x]) of the two sensors (1, 2), which are approximately the same, but unknown. The output characteristic of the first sensor (1) is subdivided into partial measuring ranges whose width is of the same size as a prescribed constant difference value (a) through which the values (x, x+a), simultaneously determined by the two sensors (1, 2), of the physical quantity differ from one another. With the aid of measurement results of the second sensor (2), in the course of the method, starting from known coordinate values (f[x0]-,x0) of an initial point (A) of the output characteristic of the first sensor (1) a known part of the output characteristic is increasingly expanded in the direction of rising values of the physical quantity by new, known partial measurement ranges, two adjacent, known partial measurement ranges overlapping in each case at least for an abscissa value (xk).

Abstract: The purpose of the façade plate, which is intended, in particular, for panelling the façade between window openings in a building fitted with transparent glass panes, for example insulating glass panes, is to produce a glass façade which is visually uniform in outward appearance. The façade panel has a transparent glass backing at the back of which there is a metal oxide coating to match the outer appearance of the façade panel in reflection and hue to that of the glass panes and an essentially optically dense outer layer applied to this coating on the side remote from the glass backing. The panel is characterised in that an inner layer (12) formed as a light-transparent metal or metal-alloy layer is applied to the glass backing (10) and its thickness is such that it reduces the light transparency of the glass backing (10) coated with it by 30 % to 85 % compared with the uncoated glass backing (10), in that the metal oxide layer (14) adjacent to the inner layer (12) is formed as a dielectric layer composed of at least one metal oxide and has an optical thickness in the range from 60 nm to 100 nm, in that the outer layer (10) is formed as such a metal or metal-alloy layer, in that the light transparency of the finally coated glass backing (10) is < 5 % and its light reflection in the outer appearance is in the range from 8 to 25 %, and in that the metals used for the inner layer (12) and the outer layer (10) are chosen in such a way that the ratio n/k of the real part n and the imaginary part k of the complex refractive index of these layers is between 0.2 and 5.

Abstract: Meta-hydroxyphenylacetylenes are produced from phenyl-substituted ketal or acetal precursors. Using biotransformation processes, these precursors serve as substrates that are converted to cis-dihydrodiol intermediates. The cis-dihydrodiols can be converted chemically to the corresponding meta-substituted compounds, e.g., meta-substituted phenols, and then to m-hydroxyphenylacetylene, which is an intermediate needed to produce acetylene-terminated resins. The biotransformation step employs arene-2,3-dioxygenase in intra- or extra- cellular form.

Abstract: A high speed data packet switching circuit has a software controlled primary processing unit (12), a plurality of network interface units (40a-40n) connected to a plurality of networks for receiving incoming data packet streams and for transmitting outgoing data packet streams, a plurality of high speed data stream hardware control circuits (14a-14p) for processing data packets in response to instructions from the primary processing unit (12) and circuitry for interconnecting the primary processing unit (12), the interface units (40a-40n), and the data stream control circuits (14a-14p). The primary processing unit (12), receives from the network interface unit (40a-40n) at least a first one of the data packets of each new data packet stream and assigns that stream to be processed by one of the data stream control circuits (14a-14p) without further processing by the primary processing unit (12). The apparatus and method thus perform routine, repetitive processing steps on the further packets of the data stream using the high speed hardware (14a-14p), while the initial processing and other non-repetitive or special processing of the data packets are performed in software. Particular hardware is described for effecting the high speed hardware processing of the data packets.
