Abstract: Driven rotatory yarn guide urges the yarn against force transducer (4) to produce an electrical tension dependant signal. The yarn path is also determined by fixed guide. Pref. the rotating yarn guide includes flat or curved vanes or pins fitted to a rotating plate or shaft. The strain guide is attached to a flexible plate. One or a pair tension sensors are provided either side of the yarn. Accurate tension measurements with reduced yarn damage (as compared to sensors which constantly contact yarn) and low yarn friction are achieved.

Abstract: The system to control the winding of yarn on to a bobbin uses a tension sensor to give a periodic measurement of the yarn tension to be compared with a pre-set value which is either constant or proportional to the increasing dia. of the bobbin, so that the rotary speed of the bobbin can be controlled throughout the winding operation. The system gives a continuing monitoring action on the yarn without imposing friction which could lead to abrasive damage of the yarn, and without requiring complex mechanical components to register yarn tension.

Abstract: PURPOSE:To detect abnormal oxygen density with high precision by detecting the variation rate of a partial oxygen pressure by a detector after equalizing the partial oxygen pressure of detected gas to that of reference one by forming a short circuit between electrodes provided to both internal and external sides of a partition wall of a solid-state electrolyte. CONSTITUTION:Porous electrodes 5 and 6 are provided on external and internal surfaces of partition wall 1 of a solid-state electrolyte to form an oxygen concentration cell and reference gas 4 is sealed in airtight container formed of partition wall 1. Then, while the external surface of container 3 is exposed to detected gas, switch 13 of short circuit 8 for electrodes 5 and 6 is closed and it is confirmed that reference gas 4 becomes equal in partial oxygen pressure to the detected gas. Then, switch 13 is opened to make a comparison the variation in partial oxygen pressure of the detected gas and a set value by detection circuit 9 and when it exceeds the set value, alarm circuit 17 is put into operation. Therefore, the oxygen concentration cell never generates electromotive force until the oxygen density of the detected gas varies, so that detection precision can be improved.

Abstract: PURPOSE:To heighten a rate of success in case of the change-over of yarn, by varying the set value of the tension of a tension controller before changing over yarn, and by changing over yarn after the winding tension of yarn strips wound by means of a spindle under a winding condition becomes high. CONSTITUTION:When a spindle 10 driven by means of a motor 19 is located at the winding side and the quantity of yarn strips 2 wound reaches fixed value, the output of an adder 32 changes to E+e from E when operating relays 35, 36, and the set value of tension rises only by 10-50%. The gain of a tension controller 31 is 1.3-8 at an operational amplifier 33. When the spindle 10 is shifted to the waiting side and the change-over of yarn is completed, winding tension and control gain become to value before alteration if stopping the action of the relays 35, 36. Thus, the winding tension of the winding yarn strips 2 rises when the spindle, which is winding at the winding side, begins to move to the waiting side from the winding side, and returns to original value when the change-over of yarn is finished.
