Title: Method and device for controlling sucking action of yarn end holding suction pipe in automatic winder
Inventor: KAMEOKA TADASHI
IPC: B65H54/86
Filed: 1983-02-07
Abstract: PURPOSE:To prevent the waste of energy for suction by opening the suction passage of a yarn end holding suction pipe only during the period after carrying out end breakage correcting action at the time of end breakage until an ending unit starts to move. CONSTITUTION:The yarn drawn out of a cop 1 passes through an unwinding accelerator 4, a tension motor 6, yarn clearer 7, and is wound up as a cheese package P. If end breakage occurs at a point between said clearance 7 and a drum 2, the lower side yarn end 3a is kept held through a pipe opening 8 due to the sucking action of a suction pipe 9. At the time of end breakage, in such a construction, when an ending unit 16 comes to a winding unit with an end breakage, and stops, a magnet sensitive switch 21 is turned on by means of a magnet piece 23 fixed to the ending unit 16, causing a closing device 15 to be opened through a control part 17. Thereby suction force is effected to the suction pipe 9 which is connected to a suction fan through a duct 13.

Title: Variable-length exhaust pipe for two-cycle engine
Inventor: SHIOBARA SHIYOUICHI
IPC: F02B75/02
Filed: 1979-02-21
Abstract: PURPOSE: To apply reflective pulsation to an exhaust port at appropriate time in high and low speed revolution, prevent blowing-through and improve the performance of an engine, by altering the length of an exhaust pipe depending on the revolution speed of the engine.  
     CONSTITUTION: A rotor d is rotated manually or automatically by a mechanism such as a governor depending on the revolution speed of an engine A. Setting is effected so that the communication passages d 1 , d 2  of the rotor d correspond to communication holes c 1 , c 2 , c 1 ', c 2 ' in slow revolution. In that case, the ends of an exhaust pipe b 1  connected to a switching chamber communicate with an accessory passage pipe 4 through the communication holes d 1 , d 2  so that the exhaust pipe becomes a long exhaust passage extending from an exhaust port 1 to an expansion pipe b 2 . The return of reflective pulsation to the exhaust port 1 through the exhaust passage is decelerated so that the reflective pulsation acts to the exhaust port 1 at appropriate time, namely, synchronously with blowing-through. In rapid revolution, the rotor d is rotated in reverse by 180° to define a short exhaust passage to cause action inverse to that described above.
