    • A control system is established wherein, when there is a flow of continuous web material (2), an identification phase is provided by increasing the torque signal to a pull roll motor (13) until slippage between the pull roll (12) and continuous web is created at a breakaway torque point, the value of which is measurable. The pull roll motor is then caused to be driven by a signal which creates a motor torque output which is of a value less than the breakaway torque point. Thus, no slippage can occur. As the motor is driven at the lower torque value, a calibration phase is entered wherein an encoder output of the pull roll is properly equated with that of a measuring wheel (9), this phase occuring at a time when there can be no slip between the web-roll interface. The identification-calibration process can be repeated as often as desired. The control system further includes the ability to cause acceleration of the pull roll after the web has been severed upstream to thereby accelerate the tail or downstream portion of the severed discontinuous web until a desired gap is created for use in a slitting device (6). At this point, which is subsequent to the identification-calibration phases, the control returns the motor input to the lower torque value.
    • 建立了一种控制系统,其中当存在连续幅材材料(2)的流动时,通过将拉力马达(13)的扭矩信号增加直到牵引辊(12)和连续幅材(12)之间滑动来提供识别阶段 在分离转矩点处产生,其值是可测量的。 然后通过产生具有小于分离转矩点的值的电动机转矩输出的信号使拉辊电动机驱动。 因此,不会发生滑动。 当电机以较低的扭矩值被驱动时,进入校准阶段,其中拉辊的编码器输出被适当地等于测量轮(9)的编码器输出,该相位在两相之间没有滑移之间发生 网络卷界面。 可以根据需要经常重复识别校准过程。 控制系统还包括在卷材已经被上游切断之后引起拉辊的加速的能力,从而加速切断的不连续卷材的尾部或下游部分,直到产生用于分切装置(6)的期望的间隙。 此时,在识别 - 校准阶段之后,控制将马达输入返回到较低的扭矩值。

    • Novel nonlinear optical, piezoelectric, pyroelectric, waveguide, and other materials are presented together with processes for their employment and articles formed thereby. Such materials, processes and articles comprise diacetylenes and polymers formed from diacetylenic species, which polymers are amenable to close geometric, steric, structural, and electronic control. Accordingly, it is now possible to design, formulate and employ new diacetylenic species and polymers formed therefrom to provide nonlinear optic, waveguide, piezoelectric, and pyroelectric materials and devices having surprising efficiencies and degrees of effect. According to a preferred embodiment of the invention, diacetylenes which are crystallizable into crystals having a noncentrosymmetric unit cell may form single crystals or may be elaborated into a thin film upon a substrate by the Langmuir-Blodgett technique. Such films may, optionally, be polymerized either thermally or by irradiation for use in nonlinear optical and other systems. According to other preferred embodiments, diacetylenes are covalently bonded to substrates through the employment of silane species and subsequently polymerized to yield nonlinear optic and other devices having high structural integrity in addition to high efficiencies and effects.
