Title: Improvements in apparatus for the treatment of textile filaments
IPC: D01D10/04
Filed: 1950-05-08
Abstract: Apparatus for the treatment of artificial thread with various treating liquids, which are supplied to the thread while supported by the circumferential surface of a roll in a thread storing and advancing reel, includes a wiper body 84 having an inner concave surface corresponding to the curvature of the roll and having means 85 on said surface for removing excess liquid.  The thread-contacting rollers 36 ... 39 ... are driven by a gear-wheel 56 which engages gears 54 on the rollers and is driven by a motor M.  The gears 54 also drive the annular member 68 upon which the bundle B of filaments 52 is initially formed.  The member 68, in a further modification, not shown, is freely supported upon bottom rollers and may be raised by manual means to a position where it is not driven by the rollers 36 ... 39 ... , or lowered into contact with the two top rollers 39, 40 (not shown), by which it is driven, to collect the bundle B.  Each roller 36 ... 39 ... is carried by reel end-plates 48, 49 in self-aligning <PICT:0686026/IV (a)/1> <PICT:0686026/IV (a)/2> <PICT:0686026/IV (a)/3> <PICT:0686026/IV (a)/4> <PICT:0686026/IV (a)/5> bearings, held in place by bolts so that the bearings can be unbolted for ready removal of the rollers.  The rollers 36 ... 39 ... are each preferably formed with a first conical portion A followed by a longer portion B of more gentle conicity, followed, again, by a portion C of uniform diameter.  Towards the delivery end of each roller, a coned-portion D is followed by a section E of uniform diameter; the thread being dried while on portions C and D of the rollers.  Treating liquids are delivered to the reel through pipes P, P1, P2, P3 ... and removed from collecting chambers C1, C2, C3, C4 ... by pipes 125, 126, 127, 128 ... such pipes engaging telescopically within pipes 130, 131, 132, 133 ... each formed with a narrowed end so that they may project between and maintain the spacing of adjacent thread convolutions at the lower side of the reel.  The pipes 130 ... 133 ... may be carried by a manually operable device so that during threading up of the reel they may be retracted from the lower regions of the thread convolutions.  The intermingling of the treating liquids is minimized by fitting between adjacent rollers pairs of wiper shells 84 pressed into contact with the rollers along longitudinal and transverse strips 85, 86, the strips 85 removing excess liquid and the strips 86 separating treating zones.  The removed liquid escapes by way of openings 88, 89 which may be furnished with spouts.  The pressure between the wiper shells 84 and the rollers is obtained, in one modification, from spring bars 94 separated by spacing members 95.

Title: Improvements in or relating to electric mooring winches
Inventor: SHITA SEISI KINO
IPC: B66C13/26
Filed: 1963-03-23
Abstract: 961,524. Control of A.C. motors. SHINKO DENKI KABUSHIKI KAISHA. March 23, 1963, No. 11600/63. Heading H2J. A mooring winch is driven by a reversible induction motor 1, the operation of mooring a ship being initiated by placing controller 11 in a " manual " position M and moving controller 2 to a neutral position. Actuation of pushbutton 20 energizes contactor 10A, so that a 16-pole winding of the motor is energized and brake 7 is removed when the controller 2 is adjusted to its first notch. By further movement of the controller 2, the motor is operated with four or eight poles, the 4-pole connection being used for taking-up slack, the 8-pole connection after the sag in the rope has been taken up, and the 16-pole connection for inching. The winch is stopped by actuating switch 21 to apply the brake and then disconnect the motor. When the ship has been moored, means are provided to keep the tension in the mooring ropes substantially constant. This is effected by moving controller 2 to the neutral position and adjusting controller 11 to any of the " automatic " positions A1, A2 or A3. The 16-pole winding of the motor is now connectable to tappings on a three-phase auto-transformer 15. A motor-driven timer 24 closes contact 25 at regular intervals to remove the brake and energize the motor at reduced voltage, the tapping on the transformer being selected so that the desired rope-tension is obtained when the motor is stalled and its torque is at a maximum. Thus, if the rope sags, the motor winds in rapidly until a balanced condition obtains, whereupon the motor decelerates and its torque increases gradually to the desired value. If the tension overcomes the motor torque, the motor is forced to reverse and slacken the rope until a balanced condition is restored. The reverse speed of the motor is then gradually reduced until the desired tension is obtained and the motor is stopped. The contact 25 is shunted by contact 26 which is closed until the motor speed reaches a low value. The operation for restoring the desired tension in the rope is thereby initiated by the timer and is terminated by contact 25 or 26, depending upon the duration of the corrective action.
