Filed: 1951-07-25
Abstract: 693,872. Controlling a clutch-brake combination. CELANESE CORPORATION OF AMERICA. July 25, 1951 [July 27, 1950], No. 17636/51. Class 80 (ii). A starter handle 12 for a yarn winding device, adapted to rock in one plane about the axis of a spindle 11 to which it is attached for actuating the spindle-driving means of the device, and also to rock in another plane about a pivot pin 18 beyond which the end of the handle extends, is also longitudinally movable with respect to the pivot pin to vary the position of the handle end. Rotation of the spindle 11 actuates a spring-mounted tensioning idler which can cause a driving belt to grip a pulley on a, shaft 6 of the yarn winding device and thus connect or disconnect the drive. Rocking the handle 12 about the axis of the spindle 11 also engages or disengages a brake member 26 from a wheel 27 on the shaft 6. The handle 12 is hollow and contains a compression spring secured at one end by a screw 16 and at the other end abutting against the pivot pin 18; the pivot pin passes through slots 19 in the starter handle and is secured to the end of the spindle 11, the construction being such that the handle can be pushed downwards against the action of the spring. A part 23 of the starter handle extends below the pivot pin 18 and has a lip 24 which can be engaged with an expander collar 25 on the shaft 6. Juxtaposed to the collar 25 is a cone holder 8 on which a yarn package 9 is wound by rotation of the shaft 6 and a suitable yarn traverse mechanism. To remove the yarn package from the cone holder, the handle 12 is depressed against the action of the spring and rotated anti-clockwise about the pivot pin 18, Fig. 2, to engage the lip 24 with the expander collar 25, which is thus thrust into the cone holder to release the cone forming the core of the yarn package 9.

IPC: D03D51/34
Filed: 1918-10-29
Abstract: 129,190. Jackson, S. S. Oct. 29, 1918. Weft-feeler arrangements.-In a differential weft-feeler device, a contact member acted upon by the shuttle contents in a feeling action co-acts with differential devices, such as plungers or slides, to determine the relative positions of these devices; the various parts are automatically reset by a fresh bobbin, as described in Specification 129,612. As shown, a contact member a is mounted in slots in the rear ends of slides 1, 2, and is pivoted at a<1> to the slide 1. The slides rest on guides 3 in the feeler stand 4, and are held down by the out-turned ends 5 of a piece secured to the stand. The front ends of the slides 1, 2 are pivoted to levers 10, 9 free to turn on a pin 11 and normally drawn rearwards by springs 12. A controller rest or latch 14 is also pivoted to the lever 9, and a projection 14b thereon normally rests on a governor brock 16, adjustably secured to the slide 1, so that a slot 14a in the controller rest holds up the end 18 of a controller 19 secured to a shaft 20. The block 16 is set so that when the member a is substantially parallel to the normal longitudinal contour of the cop, the controller rest is held up, but, when the weft is exhausted to the predetermined extent, the slide 1 is displaced relatively to the slide 2 to such an extent that the block fails to support the controller rest, and the shaft 20 is turned to allow a catch to be engaged by the weft hammer to initiate weft-replenishment. A full bobbin moves the lever 9 sumciently far forwards to cause the co-operation of the controller end 18 and the rear end of the slot 14a to hold up the controller rest irrespective of the position of the block 16, so that the feeler devices are automatically re-set. In a modification, the member a is pivoted to the slide 2.

Title: Apparatus for stretching synthetic filaments and yarns
Inventor: PHIPPS JOHN WILDEY
IPC: D02J1/22
Filed: 1954-06-16
Abstract: <PICT:0778076/IV(a)/1> In an apparatus for drawing synthetic yarns and filaments comprising a number of units each consisting of a feed roll and a draw roll, each roll being mounted on a separate shaft, a single main drive actuates all the feed rolls through their separate drive shafts, and each individual draw roll is driven from the drive shaft of the corresponding feed roll.  As shown, a yarn 9 fed from a creel passes round a feed roll 1 and is held in contact with the feed roll by a loaded cott 10, the cott surface being a synthetic rubber compound.  The yarn then passes twice round a heated pin 11 and over a vertical hot plate 12 onto a draw roll 5 and is looped three times round the latter and a separator roll 13 mounted above the draw roll, but slightly offset from its axis; the yarn then travels via a lappet eye 14 to a bobbin (not shown). The feed roll is geared so that the ratio of the peripheral speed of the draw roll to that of the feed roll is 5 : 1.  The feed roll is connected by means of draw ratio gears 2 and 3a to a driving shaft 3 which is driven by a snake belt 4 running over a pulley 4a.  The draw roll 5 is mounted on a spindle 6 which is driven by the pulleys 7a, 7b and the V-belt 8, giving a 1 : 1 drive ratio. The draw ratio may be altered in four ways: (a) by changing the gears 2 and 3a; (b) by changing the diameter of the feed roll 1; (c) by changing the diameter of the draw roll 5; and (d) by changing the drive ratio of the pulleys 7a, 7b.  A chain, or a round or link belt may be used in place of the belt 8.  Since a large feed roll and cott may be used, the yarn obtains a good grip on the feed roll and the apparatus is therefore particularly suitable for drawing yarns or filaments of highly polymeric polymethylene terephthalate.

Abstract: 662,707. Impedance measurements. STANDARD TELEPHONES & CABLES, Ltd. July 6, 1949, No. 17855/49. Class 37. A high frequency A.C. impedance comparator comprises a generator of high frequency currents continuously variable in frequency over a selected frequency range but having stable output level over this range, a fixed standard resistor, means for supplying the generator output in series with the fixed resistor to input terminals of a network whose impedance is to be determined and D.C. means for comparing the voltage at these input terminals with that at the input to the resistor, whereby successive maximum or minimum values of impedance of the network occurring with continued variation of frequency may be determined with reference to the resistor. At radio frequencies the impedance-frequency characteristic of a long coaxial cable or equivalent network has the form shown in Fig. 1, shown in full lines for a short-circuited cable and in dotted lines for an open-circuited cable. The impedance Z is complex but becomes purely resistive at the extreme values Z1, Z2. From measurements of Z1, Z2, and the frequency separation of adjacent peaks of the same curve, together with a knowledge of the lengths of the cable, the characteristic impedance, attenuation constant, phase constant, and velocity ratio may be calculated. Fig. 3 shows a circuit by which the impedance Z may be determined in terms of a constant resistance R and the ratio of the voltages e/E. The generator voltage E is rectified at W1 and produces a D.C. potential drop across a resistance r1 The cable voltage, rectified at W2, produces a potential drop across a resistance r2 which is balanced by a detector Det against a tapped-off portion a of the drop across r1. The slider of the resistance r1 may be calibrated in terms of Z for a particular value of R. The high frequency generator is stabilized by amplified D.C. voltage feed-back derived from the rectified voltage E, which is differentially compared with a fixed reference voltage.
