  • Patent number: 9347152
    Abstract: A frictional false twister is disclosed. The twister has a plurality of rotating friction plates located between the nip of the front rollers and the yarn guide. The friction plates are staggeringly arranged for rubbing a twisted yarn. The spinning direction of the twisted yarn is opposite to the rotating direction of the friction plates. Through the action of the frictional false twister, the twist of the yarn between the false twisting device to the front nip can be increased, shortening the twisting triangle height, and increasing the spinning strength. As the yarn and the outer surface of the friction plate make relative sliding and rubbing, the friction damping force correspondingly reduces the spinning tension in the twisting triangle.

  • Patent number: 9347150
    Abstract: A filament positioning control device for composite spinning of filaments and staple fibers comprises a fixed shaft and a hollow shaft mounted thereon. Left and right spiral wheels with left and right spiral grooves are mounted on the hollow shaft. Left and right positioning plates are provided on outer sides of left and right spiral wheels, each having a guide pin engaged in a spiral groove. Each positioning plate has a guide block engaged in a guide rail. As the hollow shaft is rotated, the spiral wheels rotate accordingly and the guide pins on the left and right positioning wheels move along with the spiral grooves. Because spiral grooves on two spiral wheels have different directions, when the spiral wheels rotate, the distance between positioning grooves on the two positioning plates increases or decreases, thereby changing the distance between two filaments guided by grooves on the positioning plates.

  • Publication number: 20100325130
    Abstract: Media asset interactive search is described. In embodiments, successive keypad number inputs are received that each correlate to multiple characters of one or more different languages. The successive keypad number inputs form an accumulating search key as they are received. A database is searched for a sequence of characters that correlate to the accumulating search key after each successive keypad number input is received. A list of matching terms can then be generated where the matching terms include the sequence of characters, and the list of matching terms narrows with each successive keypad number input. Additionally, the list of the matching terms can be ordered based on a scoring system.

  • Publication number: 20080185130
    Abstract: A heat exchanger comprising an inlet chamber, an outlet chamber, and a plurality of flat tubes through which the fluid passes and is cooled by ambient air or coolant. The flat tubes are formed by extrusion and include internal fluid paths to promote cooling of the fluid passing within. The fluid paths, which are formed at the same time as the tubes, may include flanges to further promote the transfer of heat. Through the use of such extruded tubes with internal fluid paths, the need for a turbulator component commonly assembled into cooling tubes may be eliminated or minimized.
