Cotton-spinning machinery The spinning jenny is a multi-spool spinning wheel. It was invented circa 1764, its invention attributed to James Hargreaves in Stanhill, near Blackburn, Lancashire. The Water frame was developed and patented by Arkwright in the 1770s. The roving was attenuated (stretched) by drafting rollers and twisted by winding it onto a spindle. It was heavy large scale machine that needed to be driven by power, which in the late 18th century meant by a water wheel. Cotton mills were designed for the purpose by Arkwright, Jedediah Strutt and others along the River Derwent in Derbyshire. Water frames could only spin
Spinning cone that the dealcoholization must be accomplished by "physical separation techniques" which would embrace the spinning cone method. More recently, in International Wine Organization Resolutions OIV-OENO 394A-2012 and OIV-OENO 394B-2012 of June 22, 2012 EU recommended winemaking procedures were modified to permit use of the spinning cone column and membrane techniques such as reverse osmosis on wine, subject to a 20% limitation on the adjustment. That limitation is currently under review following the proposal by some EU members that it be eliminated altogether. The limitation is applicable only to products formally labeled as "wine".
