Title: Method of and apparatus for transferring thread ends from one rotating reel to another
IPC: D01D10/04
Filed: 1933-12-27
Abstract: In an arrangement for removing thread from one rotating reel, on which the thread is being wound and automatically laterally displaced, to another such reel, particularly for the liquid treatment of artificial silk continuously with production, the thread near the end of the first reel is severed and the free end so formed is brought into contact with the next reel.  Preferably, the means which causes the severance of the thread conveys the new end to the next reel.  The device may consist of a <PICT:0416231/IV/1> <PICT:0416231/IV/2> brush adapted to be moved into contact with the first reel to cause severance of the thread, and means for guiding the brush to the periphery of the second reel, including a spring for moving the brush from one reel to the other.  Thread from the spinning bath is led to the top reel 1, Fig. 2, comprising two skeleton reels 28, 29 mounted one within the other on eccentrically disposed bearings 26, 27, whereby the thread is automatically advanced axially along the reel in known manner, during which time it may be subjected to liquid treatment, such as washing, desulphurizing or scouring, by spray from the nozzle 6 fed by the pump 7 from the trough 8.  When the thread reaches the end of the reel it is picked up or severed by the brush 12, which projects through a slit 16 in the casing 5; the brush is then moved down the guideway, manually, under gravity, or under the tension of the spring 14, until it reaches position 15.  The thread end 19 then forms a loop 18 which enters a slot 17 in the casing 5 of reel 2, and is picked up by and wound on the reel 2.  This is repeated for each pair of reels.  In a modification, Fig. 4, the guide 20 for the brush is arranged so that the brush contacts with each reel; the brush is raised by the handle 13 to position 23, where it picks up a thread end, it then falls by gravity or with the help of the tension spring 14<1> to position 22, the thread being brought into contact with the periphery of the lower reel 2, to which it adheres and is wound; leaf springs may be arranged in the guide slot opposite the lower reel, to retard the fall of the brush at that point.  The brush may be about a quarter of an inch wide.

Title: Monitor circuit for determining when two separate alternating current sources have a predetermined phase relationship
IPC: G01R23/00
Filed: 1971-08-12
Abstract: 1347724 Synchronizing A.C. supplies; standby supply systems AUTOMATIC SWITCH CO 12 Aug 1971 [14 Sept 1970] 37822/71 Heading H2H [Also in Division H3] A circuit 9 for detecting when a predetermined phase relationship exists between normal and standby A.C. power sources 45 and 46 respectively comprises a pair of transistors 13, 14 which produce a signal only when the voltages of the two sources have the same sign, a unijunction transistor 25 and a capacitor 24 charged sufficiently when the signal exceeds a predetermined duration to switch on the unijunction transistor which provides an output signal. When the source voltages are out of phase the signal provided by the two transistors 13, 14 acting as an "AND" gate is insufficient to cause conduction of the transistor 25. As the source voltages approach an in-phase condition the pulse signals provided by the transistors 13, 14 have a duration which is sufficient to charge the capacitor 24 to a voltage which switches on the transistor 25. The output signal from the transistor 25 fires a thyristor 39 thereby energizing a relay coil 40. A resistor 23 is adjustable so that the transistor 25 fires a predetermined time after the transistor 14 conducts. A capacitor 29 and a resistor 30 differentiate the signal provided by the transistors 13, 14 to switch on a transistor 31 and discharge the capacitor 24 completely thereby ensuring that the capacitor 24 charges from the same level each time the transistor 14 conducts. When the normal source is available, a load in the form of a motor 47 is supplied via the closed contacts 48a, 48b of a relay coil 48. On failure of the normal source a relay coil 49 is de-energized thus opening contacts 49a and deenergizing a relay coil 50. Contacts 50f are therefore closed to start an engine which drives the source 46 to energize a relay coil 51 when the source reaches an acceptable voltage and frequency. The relay coil 48 is therefore also energized, opening the contacts 48a 48b and closing contacts 48c, 48d to connect the motor to the standby source. When the normal source is restored, since the coil 40 is only energized when the normal and standby sources approach an inphase condition, contacts 40a, 40b and a further relay coil 58 having contacts 58a, 58b ensure that the change of the motor supply back to the normal source does not occur until the sources approach the in-phase condition from a previous out-of-phase condition.
