Title: Improvements in and relating to cross winding machines for winding yarns
IPC: B65H54/74
Filed: 1938-05-11
Abstract: 493,756. Winding yarns. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES. May 11, 1938, No. 14090. Convention date, June 30, 1937. [Class 120 (ii)] In cross-winding machines, wherein the yarn guide controls the drive of the spindle as it pivots with the increasing diameter of the cheese so as to maintain a constant linear speed of winding, the ratio of transmission between the spindle and traverse drive remaining constant, the movement of the friction wheel 5 of the variable friction spindle drive 4, 5 is governed by a control ring 43, the movement of which along a screwed shaft 42, whereby it operates the wheel 5 through forks 51, 56, is controlled by a stop 59 moved by the yarnguide frame 22. The traverse cam shaft is driven from the spindle shaft by gears 13, 12, and drives the shaft 42 very slowly through worm gearing 33, 34, 37, 41. The shaft 42 has a screw-thread of sawtooth profile, and the control ring 43 carries threaded jaws gripped by a band 48 so as normally to rotate with the shaft 42 without translation. The control ring also carries a stop 49 engaged by the stop 59 on a slide 30, which is moved by the yarn-guide frame through levers 23, 26, so as to arrest the rotation of the control ring 43, with consequent translation, and thereby to move the wheel 5 across the face of the disc 4. The parts may be returned to the initial position by pressing the frame 22, a stop 60 on the slide 30 engaging the fork 51 and the control ring slipping along the shaft by the radial displacement of the jaws over the saw-teeth.

Title: Non-reciprocal wave-guide
IPC: H01P1/365
Filed: 1963-04-11
Abstract: 1,028,705. Non-reciprocal waveguide devices. P. E. LJUNG. April 11, 1963, No. 14631/63. Heading H1W. In order to obtain increased band width in a resonance isolator or non-reciprocal phaseshifter, the biasing magnetic field is arranged to increase monotonically in strength in a direction transverse to the axis of the waveguide towards the edge of the waveguide. As shown, two ferrite strips 1 are arranged on the broad walls of a rectangular waveguide 2 in the vicinity of the point where the magnetic vector is circularly polarized. This point varies with frequency and to each value of frequency corresponds a value of the biasing field necessary to produce resonance. Thus, over a band of frequencies the point varies over the width of the ferrite strips and, according to the invention, the biasing field is likewise varied to produce resonance over the whole band. This may be done by varying the dimensions of the air gap of the magnet or by placing the pole-pieces in such a position (broken line 4) that the maximum field occurs at the outside edges of the strips. The strips are staggered axially by 90 degrees to reduce reflections.
