Abstract: This project work deals to investigate the interactive impact of cylinder speed and roller gauge setting of breaker drawing frame on ring spun combed yarn evenness and imperfections. In this work, carded slivers were produced by keeping cylinder rpm of 750 rpm, 800 rpm and 850 rpm while subsequent roller gauge settings (front zone/ back zone) in dr... Show More

Abstract: The T-Coupler or the magic tee (or magic T or hybrid tee) is a hybrid or 3 dB coupler used in microwave systems. It is an alternative to the rat-race coupler. In contrast to the rat-race, the three-dimensional structure of the magic tee makes it less readily constructed in planar technologies such as micro strip or strip line. The magic tee was ori...
