Kinematics of Rotary Dobby and Analysis of Heald Frame Motion in Weaving Process
No full textIn this study, a mechanism model is introduced then kinematic design and analysis equations are presented for a rotary dobby. Heald frame motion curve is obtained and analyzed. Mechanism parameters affecting heald frame motion are discussed. It is shown that heald frame motion characteristics were mainly determined by the design of modulator mechanism. Eccentric mechanism of a rotary dobby also had a significant effect on heald frame motion. © 2008, SAGE Publications. All rights reserved
The latest on Apertif
No full textWe describe a focal plane array (FPA) system, called Apertif, that is being developed for theWesterbork Synthesis Radio Telescope (WSRT). The aim of Apertif is, at frequencies from 1.0 to1.7 GHz, to increase its instantaneous field of view by a factor of 37 and its observing bandwidth to 300 MHz with high spectral resolution. This system will turn the WSRT into an effective survey telescope with scientific applications ranging from deep surveys of the northern sky of HI and OH emission and polarised continuum, to efficient searches for pulsars and transients. We present results obtained with a prototype FPA installed in one of the WSRT dishes. The results obtained with this prototype demonstrate that FPAs do have the required performance and that they can be used to turn radio telescopes into very effective survey instrument
