A Statistical Analysis of Yarn Breakage on Spinning Frame
The problem of yarn breakage during spinning is quite serious, but it is difficult to predict the number of yarn breakages, because the tension and strength of the yarn always vary. The author has used simple mathematical models of the variation of the tension and the strength of the yarn, and calculated the probability of yarn breakages. The result has shown that the variation of the yarn stre...
متن کاملA Breakage-Stop System for Linen Wet Spinning Frame
A multi-way control system for spun yarn breakage detecting and tow stopping is presented for linen wet spinning frame upgrade in medium-sized businesses of southeastern China. The signals from periodic rotations of spun yarns are picked by piezoelectric sensors. After input protection and multiplexers, the weak voltage signal from gated channel is processed through links including voltage foll...
متن کاملOrientifold and stringy frame of the Kerr Spinning Particle
We show that the frame of the Kerr spinning particle consists of two topologically coupled strings. One of them is the Kerr singular ring representing a string with an orientifold world-sheet. It has electromagnetic excitations (traveling waves), which corresponds to the old model of the Kerr’s microgeon. The excitations induce the appearance of the extra axial string which is topologically cou...
متن کاملSpinning Particles on Spacelike Hypersurfaces and their Rest-Frame Description
A new spinning particle with a definite sign of the energy is defined on spacelike hypersurfaces after a critical discussion of the standard spinning particles. They are the pseudoclassical basis of the positive energy (12 , 0) [or negative energy (0, 12)] parts of the ( 1 2 , 1 2) solutions of the Dirac equation. The study of the isolated system of N such spinning charged particles plus the el...
متن کاملEnergy Spectra of spinning particles around spinning strings in
Riemannian Killing conserved currents are used to find the energy spectra of classical spinning particles moving around a spinning string in Einstein-Cartan (EC) theory of gravity. It is shown that a continuos spectrum is obtained for planar open orbits while a discrete spectrum is obtained for circular planar orbits. A spin-spin effect between the spin of the test particle and the spin of the ...
