Patent GB-1290571-A (GB)
IPC: B65H69/00
Filed: 1970-02-02
Abstract: 1290571 Gripping moving yarn ends ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI 2 Feb 1970 [7 Feb 1969] 4810/70 Headings DIC and D1J A method of gripping a moving yarn end in textile machines, e.g. automatic winding machines and warping machines, comprises constraining yarn 1 to move in a path having a first part extending in one direction from a yarn feeding mechanism, e.g. rollers 2, 3 to a guide 4, and a second part extending in a different direction, turned towards said one side, from the guide 4, and towards a yarn withdrawing mechanism 16, the first part of the path extending past a directing member 11 disposed within the angle included between the first and second parts, and the second part of the path extending past a gripping mechanism 5 disposed on the side of the second part remote from the directing member 11, whereby when a trailing end of yarn leaves the feeding mechanism 2, 3, it experiences a whiplash effect which takes it out of the path into the gripping mechanism, as shown in dotted lines in Figure 4. In operation, in the event of a yarn break, the release in tension in the yarn as the end passes through the nip rollers 2, 3 causes the yarn to be thrown up round the guide 4 and into the jaws of the gripper 5, the directing member 11 which is preferably in the form of a sheet metal plate assisting in throwing the yarn towards the gripper. At the time of yarn break, a yarn sensor upstream of the feed rollers 2, 3 sends a signal to a yarn feeder to grip the end of yarn on the supply cap and to bring it up to the knotter 10. The yarn sensor also sends a signal to effect one revolution of a camshaft 14. Rotation of a cam on the shaft 14 moves feeders 12 to push the yarn between the gripper 5 and the withdrawal mechanism 16 into the knotter 10 with the yarn end from the supply cap. Rotation of a further cam on the shaft 14 operates the knotter 10 to knot the two yarn ends and to cut off the ends which are then sucked off at 33, 34. A further cam on the shaft 14 rotates to operate levers to open the jaws of the gripper 5 to release the tied yarn and processing of the yarn continues. The feeders 12 and the jaws of the grippers are returned to their original positions by means of springs. The yarn withdrawal mechanism 16 may be in the form of a magazine from which yarn is taken to be wound on a cross-wound bobbin, a reserve of yarn being maintained in the magazine so that the winding of the bobbin need not stop in the event of a yarn break or cap change.

As shown, in which the stack shafts 1-3 are curved and through which biscuits K are fed by a vibrator 29, the stack formation commences with the expulsion of a half-stack from the shafts 1-3 by the push members 9 on to a half stack already positioned on the conveyer 5. The stack with a counter holder 10 pivoted above the conveyer 5 to act as an abutment during the transference of goods in two layers into the first row of the conveyer, and a collector push formed in a previous operation is pushed by the member 11 into a second conveyer row, and the member 11 between stacks 2 and 3 pushes the stack in the second row into the third row of the conveyer which is then stepped forward by one stack row. The transfer elements are driven by a cam controlled linkage from a drive shaft 13.

Abstract: 1303106 Stranding machines, flyer twisting devices NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP and YOSHIDA ENG CO Ltd 23 Jan 1970 3456/70 Headings DID and D1T A plurality of wires are withdrawn from a canister P or bobbin B supported on a tray 42, pass over a guide roller R 1  above the supply source, and travel downward, guided by roller R 2 , onto a flyer 8 rotated about the tray by belt-driven wheel 5, and are withdrawn along the rotational axis of the flyer. The wire is thus twisted once at roller R, and again between rollers R 3  and R 4  on each revolution of the flyer. Where several wires are stranded together, being withdrawn from coaxially arranged canisters (Fig. 1) or bobbins (Fig. 6), they pass first through a die 11a which, together with the roller R 1 , is rotated by links 12, 12' attached to the flyer, one of which links may carry guide rings 12a, 12b for the wire. The tray 42 is maintained still, or rotated to provide additional twisting, by planet gears 7a, 7b mounted on a shaft in wheel 5 and engaging sun gears 21, 41 the former of which is fixed (Figs. 1 and 6), or by a corresponding belt or chain drive. Instead of using links 12, 12', the die 11a and roller R 1  may be independently driven, in which case a ring may be provided around the wire path (Fig. 7) to prevent ballooning. Several of these apparatuses may be arranged in rows to supply twisted single wires, pairs, triples or quads to another stranding machine for further twisting together (Fig. 2, not shown).

As shown for measuring the load on an axle of a road vehicle with the axle below the suspension springs, the load cell is clamped between the springs 2 (Fig.3) and the saddle plate 6 for the axle. The transducer comprises an elliptical steel tube 17 whose upper flat face is bolted between plates 18, 19 to the spring assembly 2 and whose lower flat face is clamped between plate 20 and the saddle plate 6. Plate 19, 20 have matching dovetails which are normally spaced by a gap d. A bolt 22 passing longitudinally through clearance holes in plates 19, 20 is provided centrally with flat portions 35, 36 on which strain gauge resistors 27 are mounted. The bolt is rigidly attached to the tube 17 by nuts 23, 24 and curved washers 25, 26. The transducer assembly is located centrally by means of pins 32, 33 and holes 31, 34. A load on the axle produces a distortion of the tubular members 17 and the resulting change in others in bolt 22 is sensed by the strain gauge resistors 27.

The ethylene may be copolymerized with minor proportions of propylene or vinyl acetate, and chain transfer agents, e.g. hydrogen, alkanes cycloalkanes and alkenes, may be added to one or more zones. The free radical initiator may be an organic peroxide, a perester or azonitrile.

The halide may be a titanium trichloride prepared by reducing titanium tetrachloride with hydrogen, aluminium or an aluminium alkyl, and which has preferably been dispersed by using it, optionally with an organoaluminium activator, to polymerize ethylene or a C 5-16  α-olefin in a preliminary reaction zone. In examples ethylene is polymerized in the presence of (1) nonanoyl peroxide and (2) diisopropylperoxydicarbonate, and in further zones containing catalysts formed from diethyl aluminium chloride and titanium trichloride formed by reducing the tetrachloride with aluminium ethyl sesquichloride and using the product to polymerize hexene-1.

Abstract: An apparatus and method for the thermal treatment of an object, such as a glass optical fiber preform. The downtime of an optical fiber drawing apparatus can be considerably shortened, by providing preforms which have pre-optimized draw bulbs (30). Pre-optimized draw bulbs (30) are provided which are already appropriately melted off at the tip. A heating furnace (1) is used for such thermal pretreatment (pre-optimization) of the preforms (2) and which does not contaminate the quartz glass. Utilizing preforms (2) which have pre-optimized draw bulbs advantageously increase throughput of the draw apparatus. In accordance with one embodiment, a heating furnace (1) that meets these requirements includes a cylindrical heating chamber (3-5), heat insulation (6-9) surrounding the heating chamber on all sides, several gas burners (12-13) firing onto the tip of the rotating preform (2) through lateral heating chamber openings (10-11), and a frame (14). Since the preform (2) softens after a temperature of about T > 1750  DEG C, correspondingly high temperatures must be generated in the heating chamber (3-5). Therefore, both the heating chamber (3-5) and the gas burners (12-13) are made of quartz glass or a ceramic material.
