Title: Process and apparatus for compensating the yarn tension difference between two yarns on a spindle drive type winding machine
IPC: B65H59/38
Filed: 1972-07-19
Abstract: 1367223 Tension control in double strand winding machines STORII & H YAMAMOTO 19 July 1972 [27 Nov 1971] 33716/72 Heading D1D In a machine for winding two packages on a single spindle 18 driven by a motor 19 each strand A, B passes under a dancer roller 3a, 3b on a dancer arm 2a, 2b freely pivoted on an axle 1. The dancer arms upwardly engage a spring biassed lever 4, also freely pivoted on axle 1, and downwardly engage a lever arm 7 which is fixed to axle 1. The axle operates a differential transformer 16 so that downward displacement of either or both dancer arms, due to reduced tension in the respective strand, increases the voltage supplied to motor 19 thus increasing its speed and restoring the tension. Upward dancer arm displacement, due to increased tension in the respective strand, leaves the lever arm 7 in the horizontal position and is countered by a spring 6. Mathematical expressions for the tension ranges allowable in strands A and B are given.

Title: Inverters
IPC: H02M7/5387
Filed: 1971-07-23
Abstract: 1357427 Inverters WESTINGHOUSE BRAKE & SIGNAL CO Ltd 20 July 1972 [23 July 1971] 34783/71 Heading H2F [Also in Division H3] An inverter comprises means for converting a D.C. input to an n phase, n wire output and responsive to the signals from a drive signal generator which signals include components at the fundamental frequency of the alternating output and certain odd harmonics thereof preferably "Triplex" harmonics, so that each phase, i.e. harmonics, the order of which is divisible by 3, output of the inverter includes harmonics which in conjunction with the harmonic components of other phase voltages result in a sinusoidal line-to-line waveform of a higher amplitude than that formed by the fundamental of each phase voltage. As shown in Fig. 3, when the inverter is driven by a sine wave, the peak values do not occur at each phase output coincidentally, curves 33, 32, which result in the line-to-line voltage curve 31. When the inverter is driven as specified above, the flat-topped curves 34, 35 result and it may be seen that their maxima occur coincidentally which produce the curve 31 but owing to their lower maxima, draw less power from the D.C. source. Protection.-Protection devices for the main converting elements include means responsive to the instantaneous values of current and voltage at an element to produce a signal representative of the instantaneous power dissipation in the device and an electrical network responsive to this signal and adapted to simulate the instantaneous thermal characteristics of the device at that power dissipation in relation to the duration of this power dissipation to indicate whether or not an allowable thermal condition is exceeded. Drive signal generator, Fig. 12, comprises 3 integrating stages 121-123 arranged in an oscillating loop to provide a 3-phase sinusoidal output at the tapping points on resistors 135- 137. These phase outputs are then applied to a wave-shaping circuit where the required odd harmonics are generated. This comprises for each phase a pair of oppositely poled diodes 126-131, the diodes of each polarity being connected to a common point, each common point being connected through an individual Zener diode 132, 133 and a common load resistor 134 to a neutral point N. The Zener diodes thereby conduct at the peaks of the waveforms to generate a voltage across resistor 134. The voltage across the resistor 134 will be the required harmonic component.
