Title: Dynamic proportional-integral-derivative (PID) method for plate straightening based on changes in yield strength
Inventor: YING HU
IPC: B21D1/02
Filed: 2022-11-30
Abstract: The PID method for plate straightening is based on changes in yield strength. The method includes the steps of determining 101 yield strength of a plate at an initial temperature and calculating 102 a predicted straightening force of each straightening roll based on the yield strength at the initial temperature. A measured straightening force of each straightening roll is obtained 103. Yield strength errors are determined at front 104, middle 105, and rear 106 using a numerical approximation method based on an error between a predicted straightening force and a measured straightening force of a previous straightening roll, a current straightening roll, and a next straightening roll respectively. Parameters of a PID controller are determined 107 based on the yield strength errors at the front, middle, and rear. A target reduction of a corresponding straightening roll is calculated 108 based on the yield strength error at the middle and the yield strength at the initial temperature. A measured reduction of the current straightening roll is adjusted 109 using the PID controller with the parameters determined based on the target reduction. Step 102 may include calculating reduction, variation of ratio of curvature, and elastic bending moment of each straightening roll.

Abstract: A handheld power tool (1) has a switchable gear component (32, 36) that can be actuated by a selector switch (20). The gear component (32, 36) can be moved along a first direction (38) out of a first operating position (23) into a second operating position (25). The selector switch (20) has a first switching position (24) associated with the first operating position (23) of the gear component (32, 36) and a second switching position (26) associated with the second operating position (25) of the gear component. The selector switch (20) can be moved between the first switching position (24) and the second switching position (26), a process in which intermediate positions (27) are assumed. A springy traveling coupling (62) is coupled between the selector switch (20) and the gear component (32, 36) in such a way that, when the selector switch (20) is moved out of the first switching position (24) into the second switching position (26), a spring (64) of the traveling coupling (62) exerts force onto the gear component (32,36) in the first direction (38). A locking bolt (72) is coupled to the selector switch (20) in a positively driven manner. When the selector switch (20) is in the intermediate positions (27), the locking bolt (72) is moved into a blocking bolt position (27) in which the locking bolt (72) blocks movement of the gear component (32, 36) out of the first operating position (23) into the second operating position (25). When the selector switch (20) is in the second switching position (26), the locking bolt (72) is in a releasing bolt position (24). (Figure 1)

Abstract: The invention relates to a method for welding rotors for power generation (gas turbines, steam turbines, generators), which comprise a plurality of rotor discs arranged along a rotor axis, said method comprising the steps of: providing forged and NDT tested rotor discs (26); machining said discs (26) for weld seam preparation, said weld seam preparation comprising an inner narrow TIG welding gap and an adjoining outer SAW welding gap; stapling the discs (26) on top of each other; checking the run-out of the stapled discs (26) relative to each other and as a whole and, if necessary, adjusting the staple; melting the root of the weld without weld filler using TIG welding; increasing the weld height by narrow gap TIG welding with parent metal weld filler to allow tilting of the rotor in horizontal position. tilting the rotor in horizontal position; finalizing the welding by filling the outer SAW welding gap using SAW welding; and checking the welds of the rotor by NDT using ultrasonic testing. A costly and time-consuming additional machining step is avoided by said weld seam preparation machining step comprising preparing an optimized transition geometry of TIG welding gap to SAW welding gap transition with a first opening (28) having a first opening angle and a second opening (29) having a second opening angle greater than said first opening angle.

Abstract: The embodiments herein relate to communication and  more particularly  to secured data transmission in near field communication. The system dynamically interleaves the data to be transmitted  using randomization and transmits the dynamically interleaved data and the interleaved settings/parameters to the destination. Further  the receiver device performs dynamic de-interleaving of the received data using the received interleaved settings/parameters. Further  in order to ensure security to the data transmission  the system uses Random Skip Count (RSC) values. If necessary  new dynamic interleaving settings/parameters are calculated based on RSC value and the new settings/parameters are used to dynamically interleave the data. The process of interleaving can be performed in 2-dimensional or 3-dimensional formats. Further  in the 2-dimensional and 3-dimensional interleaving schemes  data can be first dynamically interleaved in the form of sub matrices and the sub matrices can be further dynamically interleaved to form the final dynamically interleaved data matrix.

Abstract: A driving belt has a textile supporting element composed of multi-functional threads or yarns which contain plastic fibers of high breaking strength and heat-resistant natural fibers. The driving belt also contains an electrically conductive element. The supporting element is connected to a non-crosslinked plastic covering to form an asymmetric structure. The textile supporting element can be impregnated on the side facing away from the plastic covering. The electrically conductive element is either an electrically conductive filament in the multifunctional thread or yarn or an electrically conductive layer between the supporting element and the plastic covering. This asymmetric structure results in a favorable kinematic operating behavior and high efficiency, because the neutral bending plane of the belt comes to rest at a point very near the contact surface of an element to be driven. Together with the anti-static properties and the positive connection between the supporting element and the plastic covering, the driving belt prevents the adhesion of fiber fly and makes it possible to cut it off from a supply roll as desired and connect the belt ends without any impact effect during passage over a spindle.
