Abstract: 1. A device for the checking and cancellation of a value card (12) insertable in a card reader (1) for terminal equipment, especially card-operated telephones, and containing value units, having the following features : the card reader (1) has a slot (13), through which the value card (12) can be pushed into a card receptacle (3) corresponding to the size of the value card (12) ; the card receptacle (3) is designed so that the value card (12) is guided by it and, at its edge extending perpendicularly relative to the direction of insertion, is touched by a push-out hook (6) ; the card receptacle (3), together with the value card (12) so retained, can, as a result of a pivoting movement, be brought up to a contact element (19) serving for checking and cancellation ; there are means which, as a result of interlocking, allow the pivoting movement only when the value card (12) is inserted far enough into the card receptacle (3) ; after the pivoting movement has been executed, the card receptacle (3) can be stopped, by means of a blocking device (20, 21, 22) actuated by a magnet system, in a position differing from the insertion position and serving for checking and cancellation, up to the completion of cancellation, and can subsequently be returned to the initial position via spring elements, the value card (12) being ejected from the card reader (1) by the push-out hook (6) after cancellation has taken place, characterised in that the push-out hook (6) forms one arm of a transport rocker (2), the other arm of which is formed by two claws (5) engaging round the value card (12) at its edge located opposite the push-out hook (6), and in that the pivoting movement takes place as a result of the interlocking of the transport rocker (2) with a drive device, the value card (12) first being drawn into the card reader (1) completely and the slot (13) being closed by means of a blocking slide (4), and then the pivoting movement taking place.

Abstract: In a communication network with cryptographically protected connections a unique key is used for each connection between two subscribers, so that when one or more keys fall into the hands of an unauthorized person it has no consequences for the protection of the remaining connections. In a network comprising N subscribers this implies that each participant must have N-1 keys for communication with the other participants. Such a set of N-1 keys is obtained by putting a column from a NxN key matrix (main diagonal empty) at the disposal of each participant. During the connection set-up the correct unique key automatically selected by interchange of the column number. The key matrices used in the network can be regularly replaced without it being necessary to interrupt the operation of the network.

Abstract: The present invention relates to an artificial vascular graft having ultra fine fibers smaller than 0.5 denier in fineness as part of the inner wall. The artificial vascular graft of this invention is very flexible and produces very low blood leakage. The ease of performing anastomoses is greatly improved. Because of the ultra fine fiber there are many sites to which live cells adhere, the adaptability of the live cells to the fibers of the vascular graft increases, an excellent antithrombotic effect is exerted by the vascular graft, and the formation of the endothelial cells is satisfactory and is observed at a very early stage.

Abstract: A two-component syringe (20) includes a barrel (21) having a chamber (22) for retaining fluid (44) and a distal end (25) of the barrel (21) having a passageway (26) therethrough communicating with the chamber (22). A by-pass stopper (31) is slidably positioned in fluid-tight engagement inside the barrel (21). The stopper (31) has a distal rib contacting the barrel (21), a recess on the proximal side of the rib and a groove in the rib for allowing fluid communication between the recess and the chamber (22). This groove is positioned angularly with respect to the longitudinal access of the barrel (21) so that liquid passing therethrough is directed angularly with respect to the longitudinal axis of the barrel (21). The barrel (21) also includes a raised peripheral portion serving as a by-pass and defining a by- pass zone (34). The by-pass zone (34) is shorter than the length of the stopper (31) along the longitudinal axis of the barrel (21). The by-pass (34) is sufficiently long and raised enough to allow liquid to flow around the stopper (31) between the proximal end of the stopper (31) and the recess when the proximal end of the stopper (31) is positioned in the by-pass zone (34). Also included is a piston (36) slidably positioned in fluid-tight engagement inside the barrel (21). This piston (36) is adapted to engage a plunger rod (37) to facilitate its operation.

Abstract: A verifier for use in a personal identification system of the type in which a generator receives at least a personal account number (PAN) and a secret personal identification number (PIN) and based thereon produces digits A i 's which are present in a feedback shift register (FSR) A and digits C i 's present in a feedback shift register (FSR) C respectively. The A i 's and C i 's are mapped into D i 's which represent digits of an Offset Number which together with the PAN are recorded on the magnetic stripe of a card. To use the card, the Offset Number and the PAN are read off therefrom and an intended user enters a secret PIN. In the verifier, the PIN is operated upon to produce C i 's and the PAN is operated upon to produce A i 's. The fatter together with the D i 's of the received Offset Number are mapped by a processor (201) to form C i 's. These are compared with the C i 's by a comparator (202) to determine whether the intended card user is the rightful user.

Abstract: Un matériau composite comprend un polymère de poids moléculaire ultra-élevé et des fibres ayant des longueurs de 0,05 pouces (1270 micromètres) environ. Ce matériau composite est formé en dispersant les fibres avec des particules du polymère dans un support liquide inerte. La dispersion est passée par un filtre qui recueille les particules et les fibres en tant que structure intermédiaire dans laquelle les fibres sont orientées suivant une matrice quasi-isotrope et les particules sont dispersées dans tout ce réseau fibreux. La structure intermédiaire est enlevée du filtre, séchée, compactée puis comprimée à une température élevée de sorte que le polymère fond tandis que les fibres ne fondent pas. Lors du refroidissement un composite se forme, lequel comprend une matrice polymère continue renforcée avec les fibres entrelacées et orientée au hasard et de longueur relativement importante. Ce matériau peut être transformé en articles tels que des segments de piston ou des joints, pour obtenir une structure autolubrifiante ayant une bonne résistance à l'usure et une bonne résistance au fluage.

Abstract: 1.
