Title: Threadline tensioning device
IPC: B65H59/10
Filed: 1970-12-16
Abstract: 1318280 Tensioning E I DU PONT DE NEMOURS & CO 16 Dec 1970 [17 Dec 1969] 59770/70 Headings DID and DIM A threadline or yarn tensioning device suitable for use in high-speed yarn beaming comprises a housing with ends 12 supporting yarn inlet and outlet guides 13, 14, spaced sides 11, 11' between which extend parallel guide pins 16, and a plurality of rings 17 guided in channels 18 in the sides for free movement in planes tilted at an angle b of from 5‹ to 45‹, preferably 10‹ to 30‹, to a vertical line perpendicular to the yarn path 5. Yarn tension is determined by the weight and number of rings employed, and the tilting of the rings minimises chatter. The yarn contacting surfaces, i.e. the guides 13, 14, pins 16 and the rings, of which the cross-section may be polygonal but is preferably circular, may be made of or coated with ceramic material. The housing, of which the ends support a ring keeper pin 19, may be made of plastics material such as polystyrene, although to dampen ring chatter a rubber &c. material may be used. Some vertically oriented rings may be included, and some rings may be held out of contact with the yarn by a pin inserted between the housing ends. To promote even wear of the rings by causing them to be rotated by the yarn, the rings and guide pins 16 may be skewed at an angle of 5‹ to 45‹, preferably 5‹ to 15‹, to a horizontal line perpendicular to the yarn path 15.

IPC: H01S3/0973
Filed: 1971-12-23
Abstract: 1301639 Lasers COMPAGNIE GENERALE D'ELECTRICITE 23 Dec 1971 [30 Dec 1970] 59866/71 Heading H1C A broad transmission line structure 20, 21, 22, Fig. 2, applies pumping energy directly to a gaseous active medium contained in a cavity 30, the transmission line structure having a parabolically-shaped reflecting edge 37 at its end remote from the cavity, and the cavity being inclined at an acute angle α to the axis of symmetry 23 of the transmission line, so that pumping energy introduced at the focus F of the parabolic edge is swept uniformly from one end of the cavity to the other at a velocity equal to the propagation velocity of the stimulated emission in the cavity. Direct forward transmission of pumping energy is prevented by an arcuate slot 36. The transmission line structure comprises two metallic plates 21, 22 spaced apart by an insulating plate 20 which is relatively movable and may be rolled up progressively at an end 32. The cavity is formed by a transverse slot in a ridged portion 29 of plate 32, together with insulating strip side walls 27, 28 and end windows 39. The active medium in the cavity may be air, hydrogen or nitrogen, and may provide ultra-violet radiation. The plates 21, 22 are held at different potentials, and pumping energy is introduced at the focus F by focused pulses from an auxiliary laser 33 controlled by circuit 34, the auxiliary laser causing penetration of the plate 22 (if not already apertured) and the insulating sheet 20 beneath. The movable insulating sheet 20 is displaced by rolling up to present a fresh unbroken surface before the pumping operation is repeated. In a modification, Fig. 3, two adjacent insulating sheets 60, 61 are used, each sheet having an aligned different sized aperture filled by replaceable discs 62, 63 held by an insulating grease. The metallic plate 22 also has a cylindrical aperture 65 adjacent the focus F in which an apertured metallic disc 66 is inserted. An elongate cavity is provided in the arrangement shown in Fig. 4 in which a plurality of mutually inclined transverse slots 40-44 are formed in the metallic plate 22, the slots being optically coupled by mirrors 51-54 and the cavity terminated by end windows or mirrors 39, 55. The slots are so inclined that pumping energy transmitted along the plate after reflection at the parabolic edge 37 reaches an appropriate sweep position in each slot in turn at the same time as the generated stimulated emission. A second pumping energy sweep may be caused by reflection from a normal plate edge 57. A further pumping energy switching arrangement is shown in Fig. 5 in which a gas trigger 113 is located at the focus F, the trigger comprising electrodes 115 and 116 connected to plates 101 and 102, respectively, and located in a glass envelope 118 containing a mixture of nitrogen and hydrogen or nitrogen and sulphur hexafluoride. Direct forward transmission of pumping energy is prevented by a high impedance 122 formed by an extended portion of an external insulating gas trigger envelope 119.
