Title: Improvements in and relating to a yarn reel
IPC: B65H49/30
Filed: 1938-10-10
Abstract: 519,257. Winding yarns. MARSCHIK, C. Oct. 10, 1938, No. 29275. Convention date, Oct. 11, 1937. [Class 120 (ii)] In a skein holder or reel in which the tension of the yarn is automatically controlled as the yarn is wound and in which the circumference is reduced when the reel support is tilted downwards to reduce its circumference for the placing of the skeins thereon, the adjustment of the circumference is obtained by providing each of the elastic spokes or yarn supporting arms of the reel with a double lever device connected to a disc on the reel spindle so that a small axial displacement of the disc on the spindle gives a large variation in the circumference of the reel. The original tension of the yarn may be adjusted by hand during the winding process by a braking device embodying the disc which device is also automatically controlled by a swinging thread guide lever to maintain this adjusted tension. As shown each yarn supporting arm 7 of the reel' is formed of elastic wire and is pivoted on a bolt 6 on the reel disc 5 rotatable on the spindle 4 fixed to an arm 1 pivotally mounted in a support 3. Short arms 9 extending from the arms 7, and forming with them the double lever devices, are pivotally connected to rods 8 jointed to arm 11 of bell-crank levers pivoted in bolts 12 on the disc 5 and having their other arms 13 forked to engage a beaded pulley 14 which forms the braking device, slidable on the spindle 4, and frictionally engaging the face of the disc ; the ends of the arms 13 may be plain to engage a fluted pulley. The pulley 14 is slidable but not rotatable on a sleeve 15 connected by a pin and slot 15<1> with the spindle 4, and is pressed against the disc 5 by a spring 22 bearing against a notched wheel 18 engaging a screw threaded portion 17 of the sleeve and having a stepped portion carrying a ring 19 rigidly connected to the swinging thread guide lever 20. The end of a snap spring 21 carried by the ring 19 is adapted to engage one of the notches of the wheel 18 and by lifting the spring and turning the wheel, the spring 22 is adjusted to vary the braking effect of the pulley on the disc 5 and the original tension in the yarn; if the guide 20 is moved during the winding the wheel 18 is turned and moved along the sleeve to adjust the spring 22 and the braking effect and maintain the original tension. The sleeve 15 carries a flanged collar 15" which is engaged by studs on the arms 23 of a bell-crank lever pivoted on a bolt 24 on the arm 1 and having the other arms 23' pivoted to a rod 26 mounted on a pivot 27 on the support 3 so that as the arm 1 is drawn down, the sleeve 15 is moved to draw the pulley 14 away from the disc 5 and actuate the members 13, 11, 8, 9 and 7 to reduce the circumference of the reel. The arm 1 is locked in the working position by a spring- pressed lever 28 pivoted on the arm and engaging a notch 30 in the support 3 and the downward movement of the arm is limited by a stop 32.

Abstract: 1531126 Multiplexing; frame synchronization SIEMENS-ALBIS AG 14 July 1977 [6 Aug 1976] 29677/77 Heading H4M A frame synchronization arrangement for a receiver in a PCM system in which a frame synchronization word and a synchronizing check bit are alternately transmitted in the synchronizing time channel comprises a frame word extractor RWE which emits a frame word pulse rwi in response to each frame synchronizing word and a frame bit pulse rbi in response to each check bit, a resettable channel counter KLZ and a resetting circuit RSS which is responsive to the pulses rwi and rbi. The circuit RSS, Fig. 2 (not shown) comprises a word pulse counter (ZI) which is arranged to count consecutive break-downs of frame word pulses, a bistable stage (BS) which is responsive to the counter (ZI) reaching a first predetermined count to be set to a specific state in which it determines a second predetermined count of the counter for the frame-correct occurrence of frame word pulses, a gate (TS) which is responsive to the bistable stage being in said specific state to conduct any frame word pulse which occurs as a resetting pulse rsi to the channel counter KLZ, a counter (Z2) which counts frame word pulses which occur when the bistable stage is in said specific state and upon reaching a third predetermined count blocks the emission of further frame word pulses to the channel counter KLZ, and a bit pulse counter (Z3) which is arranged to count frame bit pulses which occur correctly following the occurrence of a frame word pulse which occurs while the bistable stage is in said specific state. The arrangement is such that if the bit pulse counter reaches a fourth predetermined count a frame word pulse counting input of the counter (Z1) is enabled after a delay of two pulse frames and if the fourth predetermined count is not reached the pulse counting input is blocked. Preferably the first predetermined count is equal to 3, whilst the second, third and fourth predetermined counts are each equal to 1, so that a resynchronizing process is initiated not until the frame synchronizing word has failed to appear three times consecutively, the frame alarm state denoting this loss of synchronization being maintained until both a synchronizing check bit and a synchronizing word have been detected in consecutive synchronizing time slots.
