Abstract: A radio frequency identification (RFID) automatic vehicle identification (AVI) system configured to mitigate signal interference, the system comprising a plurality of RFID readers, comprising a first RFID reader and a second RFID reader; and a plurality of antennas, wherein a first antenna is connected to the first RFID reader and a second antenna is connected to the second RFID reader. Prior to the first RFID reader transmitting a signal through the first antenna, the first RFID reader samples a received radio frequency (RF) signal from the first antenna, and if the received RF signal meets predetermined strength and frequency criteria, the first RFID reader inhibits transmission of the signal through the first antenna.

Abstract: A traversing core yarn guide for use on spinning frames mounts to an existing silver trumpet bar in a manner which allows the bar to be traversed, while the guide is provided with a hinge that allows it to be raised to a position which will not interfere with a concurrent raising of the top roll mechanism of the frame. The guide includes an interchangeable wing portion having yarn guiding inserts on its respective ends, such inserts being either of a ceramic, porcelain, pin or pulley construction.

Abstract: The ring mount is of a two-piece construction and includes a hard plastic mounting support fixed in an annular opening in the ring rail. An annular recess is provided in the upper inner portion of the mounting support. A soft plastic insert is adapted to closely fit within the annular recess of the mounting support and is provided with an annular groove in the inner surface which is adapted to receive and support the lower flange of the ring. The two-piece ring mount is positioned between the metallic ring rail and the metallic ring and provides noise and vibration dampening means for resiliently supporting the metallic ring on the ring rail.

Abstract: A spline coupling positionable within a gear housing for coupling a flyer to the spindle gear of a spindle has an integrally attached spindle washer for effecting a seal about the spline coupling and spindle gears. The spindle washer is attached to an uppermost portion of the spline coupling and serves to prevent oil, water and lint from reaching both the spindle gear and the base of a bobbin positionable over the spindle.
