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.

Abstract: In one embodiment, a method includes receiving a first activity map. A first mobile client determines first positioning information based on a first position of the first mobile client. The first mobile client generates a second activity map using the first positioning information of the first mobile client as a damping factor for activity in the first activity map. The first mobile client sends the second activity map to a balancing manager. A third activity map is received from the balancing manager. The third activity map is based on the second activity map from the first mobile client and a second activity map from a second mobile client. The second activity map from the second mobile client is generated using second positioning information for a second position of the second mobile client as the damping factor.

Abstract: Stretching apparatus for synthetic filaments is provided with plates (5.1 and 5.2) located in a stretching bath S in spaced apart facing relation to one another to provide a space between which the filaments are drawn along a path. The plates are structured in accordance with the invention (as shown in FIGS. 7 to 16a) so that vibration of the yarn during the passage through the stretching bath is suppressed. At least one of the plates is penetrated by holes which open at the plate surface facing the yarn path.

Abstract: The stretching chamber arrangement comprises a stretching chamber with a first closeable feed conduit, a return conduit, a liquid container and a pump for the circulation of the liquid through the stretching chamber. For premoistening the yarns to prevent dry friction during the start-up of the arrangement, a second feed conduit is provided which by-passes the closing valve of the first feed conduit and which opens out into the yarn duct through small premoistening openings situated in the direction of the yarn travel in the area of the yarn entrance in front of the first yarn guiding element of the arrangement.

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.

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.

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.

Abstract: The drawroll unit has a heatable galette in which the shaft of the gallette is mounted in bearings which, in turn, are mounted via vibration damping devices in a stationary housing. The vibration damping devices may be in the form of bodies of interlaced wire, O-rings or the like. The vibration damping devices serve to damp vibrations of the shaft in a critical speed range within the normal speed range of the rotor so that the galette can be operated at any speed within the normal speed range.

Abstract: In order to be able to operate chambers for the continuous fluid treatment of textile yarns and which comprise several chamber parts with an improved sealing effect, even at elevated pressures and temperatures when aggressive fluids are used, one or both sealing faces of superimposed sealing face pairs undergo shape correction. The shape correction opposes the elastic deformation undergone by the sealing faces when loaded under operating conditions.

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.

Abstract: A yarn winding machine is equipped to compensate the sag of the spool mandrel (5) with a speedometer roll (7) which is disposed so that it can press radially against the surface of the yarn packages being wound and which is mounted so as to damp vibrations. The mounting for the speedometer roll (7) includes a peg (17) fastened on a yoke (11) which supports the speedometer roll (7). The peg (17) extends into a hole (21) in a carrier (19) for the yoke 11 and is connected to the wall of the hole (21) through O-rings (23) on the surface of the peg (17) so that it is flexible with respect to rotation.

Abstract: After winding of a thread into a package, the thread is severed and, in order to prevent whirling of the thread end around the package, the end portion is interlaced with the package surface during the braking phase of the package. Interlacing is performed by blowing pressure jet against the thread end and the package surface within an interlacing chamber defined by a pivotally mounted shoe from which the pressure jet is emitted.

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.

Abstract: Logic signals corresponding to a detected thread break and/or thread loop in a package being wound on a bobbin are evaluated within a logic circuit to communicate the quality of a thread package. The logic signals can be processed in various ways.In one embodiment, discrimination is made of repeated logic signals produced by a single thread break.In another embodiment, the total number of logic signals are counted.Blocking arrangements can be provided to block logic signals caused by the same thread break or thread loop.

Abstract: The monitor is spaced a small distance from the curved path of the travelling thread to sense defects in the thread. In one embodiment, the monitoring means is spaced from the winding surface of a chuck to sense broken threads or an accurate build-up of the thread package. The monitoring means includes a detector head with a charge collector rod for sensing changes in electrical potential of the rod due to contact with a travelling thread part. The monitoring means can be moved away from the chuck to maintain a constant distance from the thread package being wound on a bobbin tube on the chuck.
