  • Patent number: 8730015
    Abstract: A duplication detection module may be configured to determine if data on a RFID tag is encoded. If the data on the RFID tag is not encoded, the duplication detection module may determine that the RFID tag is a duplicate RFID tag and that an item associated with the duplicate RFID tag is counterfeit. If the data on the RFID tag is encoded, the duplication detection module may cause the decoder to decode the data on the RFID tag using a private key of a receiving party as a decoding parameter. The module may check for an item identifier and a sender identifier as a part of the encoded data, determine whether the item identifier has previously been read to determine if the RFID tag was duplicated during transport and compare the sender identifier with an expected sender identifier to determine if the RFID tag was duplicated during transport.

  • Patent number: 5378377
    Abstract: Excess liquid is removed from a fast-moving thread, in that the latter is deflected, so that the liquid is hurled off, the hurled off liquid is removed from the thread, in that the thread is passed through a closed chamber, where a vacuum is produced in order to facilitate liquid evaporation and in that the thread is led through a narrow gap, so that the layer directly surrounding the thread and travelling therewith is peeled off. The combination of these drying effects constitutes one process stage. Advantageously, this process stage is performed several times in direct succession, so that in the case of a thread-protecting, small deflection angle a good thread drying can be achieved. The process is performed by an apparatus comprising several chambers (K.1-3) connected in series in the thread movement direction, the thread being deflected at the inlet and/or outlet with respect to each chamber by a deflection element (U.1-4) and passes through a narrow gap (S.1-). The chamber walls (20.

  • Patent number: 5351374
    Abstract: Threads made from thermoplastic materials are textured, in that they are heated by a delivery medium in a delivery channel and conveyed through an orifice into a stuffer box where they are stuffed to form a plug. In order to maintain plug formation constant, the orifice area is monitored in a sensory manner and the measured signals are used for monitoring purposes as a measured quantity in a control loop, in which the supply of damming back medium, the conveying away speed of the plug, the position of the stuffer box walls, or the supply of delivery medium are used as manipulated variables. The measuring signals produced by monitoring can be compared with thresholds to produce control signals corresponding to the comparison result for activating alarm, warning or stopping elements.

  • Patent number: 5307547
    Abstract: Threads consisting of one or more filaments are drawn by being pulled through a braking fluid. Threads consisting of a plurality of filaments are formed into a ribbon for the drawing process. Inside the drawing bath, the thread is heated to a temperature corresponding to its second order transition temperature and is braked in such a way that its tension reaches the tension necessary for drawing the filament or the filaments. Through setting and/or controlling the length of the thread path inside the braking fluid, the viscosity of the fluid, additional mechanical braking means and/or the flow characteristics in the bath, the process is made adaptable for different thread materials and different thread speeds and can be optimized for thread quality. The device for carrying out the process has a quasi-closed main chamber through which a braking fluid is circulated. An antechamber with a variable fluid level may be arranged in front of the entrance to the main chamber.

  • Patent number: 5046225
    Abstract: A method for drawing a synthetic thread having a fibril bundle delivers the thread as a ribbon of substantially parallel fibrils through a drawing bath to effect a hydrodynamic braking of the filaments and simultaneous drawing of the filaments. A ceramic pin is used to form the fibrils into parallel relation and substantially in one plane. A second ceramic pin may also be used as a mechanical brake to add to the hydrodynamic braking action by the liquid in the drawing bath. The base and cover of the drawing device are provided with channels to define the flow path for the bath liquid as well as inlet and outlet channels for the liquid. Suction nozzles or air nozzles may be provided at the inlet and outlet ends of the flow paths to remove excess liquid from the fibrils.

  • Patent number: 4712746
    Abstract: Winding of threads into cross-wound packages is effected by a moving traverse mechanism of a main traverse mechanism by which the thread is laid on to the package. The thread runs in a preliminary traverse mechanism between two elongated guide members which form therebetween a gap. The thread extends transverse to the guide members. The thread is additionally influenced by the preliminary traverse mechanism by means of air streams flowing in the longitudinal direction of the gap, these air streams being controlled with respect to timing. In this way, the thread is relatively uniformly tensioned, so that the operation of laying the thread into the package can be performed by the main traverse mechanism with greater precision. In the preliminary traverse mechanism, the thread practically does not come into contact with any fixed components, since no such components are required for its guidance and within the gap the thread is located in a kind of air cushion.
