Abstract: 1318413 Plied yarn COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANISATION 5 June 1970 [17 June 1969] 27327/70 Headings D1F and D1W In the production of a uniform yarn from at least two running strands, the strands 7, 8 are separately fed from a feeding point to a convergence point 10, the rates of feed being substantially equal, the strands are twisted together at the convergence point 10, and at the same time the path length between the convergence point and the feeding points is cyclically varied. In a preferred embodiment the strands 7, 8 are fed from drafting rollers 1 which are placed symmetrically about a plane containing the axis of the convergence guide 10. The converged strands are fed through a guide 2 to be twisted on to a package on a ring spinning frame. The convergence guide 10 is caused to move cyclically between a point X in the aforementioned plane and the original point Y. The convergence guide 10 may be in the form of a suction tube with a birfurcated end, forming a slot for the strands, -the bifurcated end being caused to oscillate by means of a cam arrangement. In an alternative arrangement, the convergence point is caused to vary cyclically by means of reciprocating guides which move perpendicularly towards and away from the aforementioned axis. A number of pairs of drafting rollers and associated convergence guides &c may be arranged side-by-side, separator plates being positioned between adjacent pairs.  The yarn of the present invention comprises at least two strands twisted together with plying twist which varies cyclically in intensity along the length of the yarn, and in which each strand is twisted with an alternating twist. The regions of like twist in the strands are in phase with one another in the plied structure. The regions of high intensity twist in the plied structure coincide with. regions in the strands which are of opposite twist to the plying twist.

Abstract: 335,722. Galpin, L. S. Sept. 12, 1929. Obstruction-removers.-An obstruction-removing apparatus for vehicles comprises a rigid rectangular frame 1, supporting a movable guard or shield 9 normally held in a raised inoperative position by one or more trip devices and adapted on release to travel downwards in guides 3 and to project forwardly on reaching the road, any tendency of the guard to rise in the guides when in contact with an obstruction being prevented by ratchet mechanism in which the ends of a longitudinal rod 12 on the guard engage teeth 11 in the guide-slots 10. The trip devices may be operated by hand or foot or by the engagement of a bumper with an obstruction. When the bumper bar 33 meets an obstruction it forces plungers 31 against the upper ends 26 of trip-levers 22, so that the hooked lower ends 25 of the levers are withdrawn from the stirrups 27 thus releasing the guard 9. Spring drums 18 or springs may be provided to facilitate the downward movement of the guard, which is guided into the position shown in dotted lines. To reset the guard, it is raised by knobs 16 until the hooks 25 engage the stirrups 27. The bumper bar 33 is pivotally connected as at 34 to each plunger 31 and is divided at the middle to permit the parts to swing about their pivots 34 and to be lowered about the axes of the plungers, the two parts being normally held together by a sliding bolt on one part engaging a socket in the other. In an alternative construction the trip levers 22 are mounted to turn about separate vertical pivots and are connected by a tie rod so that they move together. Spring blades 44 engaging the rod 13 of the guard may be fixed on the frame 1 to prevent the guard moving under vibration.
