Abstract: Method and apparatus for reducing residual torque in singles ring yarns, achieved by imparting two separate false twisting points on the traveling strand of fibers (or yarn) after the strand exits from the spinning triangle with a proper ratio between the belt speed and the strand feeding speed. In addition to reducing the residual torque, this double false twist technique also reduces yarn hairiness to the same level as achieved by more expensive compact spinning devices, reduces yarn twist by more than 20% and significantly enhances yarn and fabric softness. Furthermore, by combining the double false twist technique with a compact spinning device, the numbers of neps, thick and thin places are significantly reduced to produce high-quality yarns and fine-count yarns.

Abstract: An electronic device includes a circuit board, an extension card, a cooling device, and a connecting member. The extension card is coupled to the circuit board. The cooling device includes an outer casing and an inner casing received in the outer casing. The connecting member includes a fixing end and an engaging end opposite to the fixing end. The fixing end is fixedly mounted on the outer casing. The engaging end is configured for fastening the extension card on the circuit board. The outer casing moves between a first position where the engaging end fastens the extension card and a second position where the engaging end is separated from the extension card to unfasten the extension card.

Abstract: In a process for manufacturing a singles ring yarn, a method and apparatus is invented which utilizes double belts as a false twist device and incorporates it in the conventional ring spinning machine for producing a singles ring yarn. In this invention, a double-belts is applied thus two twisting points, instead of one twisting point, are adopted for the yarn false twisting to improve the false twist efficiency. Accordingly, a ratio of the velocity of the belt to the delivery speed of the yarn is controlled and the wrapping angle of the yarn on the belts is adjusted in order to obtain the desired property of the final singles ring yarn. The said invention can enhance the strength of fiber strand at the spinning triangle and thus ensure the yarns spun in a normal condition at low twist multipliers, which is unable to be obtained by the conventional ring spinning machine.
