Abstract

1. A process for address-free (symbolic) fault location by means of a loop closure in a communication transmission link for the transmission of digital communication signals from a locating end station via at least one intermediate regenerator which regenerates and/or amplifies the transmission signals in both directions of transmission and which contains a loop closure switch which serves to connect the output of the regenerator for one direction of transmission to the input of the regenerator for the opposite direction and further contains a change-over switch which connects the input of the regenerator of the opposite direction to the connected loop or to the ouptut of the transmission link of the opposite direction, wherein the locating end station transmits one single locating signal during the entire fault locating process, characterized in that commencing from the operating state, the locating signal transmitted periodically contains a code of short duration, that following a recognition time (T1) all the intermediate regenerators which receive this locating signal assume a preparation state in which a state counter (ZZ) is released and these intermediate regenerators emit a locating signal which has been modified in such a manner that the code which is still contained therein can no longer be recognised as a code by a receiving intermediate regenerator and the latter remains in the equalizer control zone and in the synchronisation zone of the phase control loop, that the intermediate regenerators which have been switched into the preparation state and which receive the modified locating signal switch back to the operating state following a hold time which corresponds approximately to the recognition time (T1), and that at the end of the hold time, in the event of an interruption in the transmission of the locating signal for a step-on time (T2) which is short in comparison to the recognition- and hold time, the intermediate regenerator which has remained in the preparation state is switched into the loop closure state and the input of the regenerator for the opposite direction is cut off from its preceding signal path, and in addition the unchanged locating signal is transmitted to the intermediate regenerator which follows in the locating direction, the state counter (ZZ) is switched on, and the switched loop closure is retained for the duration of the unmodified locating signal, which exceeds the recognition time (T1), that in the event of a further change in the locating signal for the step-on time (T2) the state counter (ZZ) in the intermediate regenerator with loop closure is switched into an end position, the loop closure in this intermediate regenerator is discontinued, and the locating signal is transmitted with its code unchanged to the intermediate regenerator with follows in the locating direction and this intermediate regenerator is switched into the loop closure state.

Description

Stukebokskruser med oppdelt trykk-kammer. Stukebox mugs with split pressure chamber.

Oppfinnelsen angår forbedringer i eller ved apparater for teksturering av tekstiltråder og den vedrører spesielt slike apparater som omfatter et stukekammer. The invention relates to improvements in or to devices for texturing textile threads and it particularly relates to such devices which include a warping chamber.

Patenthaveren har også foreslått en The patent holder has also proposed one

fremgangsmåte for teksturering eller krusing av tekstiltråder, f. eks. nylongarn, i hvilken fremgangsmåte trådene blir kruset og krusningene herdet og hvor de karakter-istiske trekk er at et mottrykk som tilføres tråden ved krusepunktet blir vedlikeholdt konstant ved hjelp av en kontinuerlig kontroll av dette trykk ved et sted som ligger mellom nevnte krusepunkt og det punkt hvor trykk først tilføres tråden inne i stu-keboksen; og ved at krusningene herdes mens tråden står under trykk inne i istuke-kammeret. method for texturing or crimping textile threads, e.g. nylon yarn, in which method the threads are crimped and the crimps hardened and where the characteristic features are that a counter pressure applied to the thread at the crimp point is maintained constant by means of a continuous control of this pressure at a place located between said crimp point and the point where pressure is first applied to the thread inside the sprue box; and by the fact that the ripples are hardened while the thread is under pressure inside the ice week chamber.

En slik fremgangsmåte tilveiebringer Such a method provides

vesentlige fordeler i forhold til tidligere kjente stukeboks-krusemetoder ved at det oppnås bedre kontroll av både krusejevnhet og herdejevnhet. significant advantages compared to previously known sprue box-mug methods in that better control of both mug uniformity and hardening uniformity is achieved.

Det er et formål med oppfinnelsen å It is an object of the invention to

tilveiebringe et apparat, som hensiktsmes-sig kan benyttes i forbindelse med den an-gitte metode. Et videre formål er å .tilveiebringe et apparat som er en forbedring av kjente stukekrusere når det gjelder reak-sjonsevnen til trykk-kontrollsystemet, når det gjelder rene linjer i krusekamme-rets indre, som skal forhindre fast-klemming av tråder og filamenter som trådene er dannet av, og videre når det gjelder tendensen til at krusningene skal fjernes når trådene trekkes ut av boksen. provide an apparatus which can be suitably used in connection with the stated method. A further purpose is to provide an apparatus which is an improvement of known stucco mugs in terms of the reactivity of the pressure control system, in terms of clean lines in the interior of the mug chamber, which will prevent the clamping of threads and filaments such as the threads is formed by, and further in terms of the tendency for the ripples to be removed when the threads are pulled out of the box.

Ifølge oppfinnelsen er stukekruseren forsynt med et delt trykk-kammer, hvis innmatnings og utmatnings endepartier er According to the invention, the stucco crusher is provided with a split pressure chamber, whose inlet and outlet end parts are

slik anordnet at de kan beveges i (begrenset avstand i lengderetningen i forhold til so arranged that they can be moved in (limited distance in the longitudinal direction in relation to

hverandre, og er belastet slik at det presses each other, and is loaded so that it is pressed

mot utmatningsendepartiet og forårsaker mottrykk for krusningen. towards the discharge end portion and causes back pressure for the ripple.

Stukeapparatet kan således omfatte klemvalser, ved hjelp av hvilke tråden presses inn i trykk-kammeret; et trykk-kammer som fortrinnsvis, men ikke nødvendig-vis har rektangulært tverrsnitt, hvilket kammer er oppdelt i et innmatningsende-parti som danner krusesonen og et utmatnings-endeparti som utgjør herdesonen, hvor sistnevnte er anordnet slik at det under trykkbelastning kan beveges i lengderetningen i begrenset utstrekning i forhold til førstnevnte og har en trådutmatningsende som er tilstrekkelig innsnevret til at det dannes et mottrykk i material-søylen inne i kammeret. The twisting apparatus can thus comprise pinch rollers, by means of which the thread is pressed into the pressure chamber; a pressure chamber which preferably, but not necessarily, has a rectangular cross-section, which chamber is divided into an infeed end part which forms the crucible zone and an outfeed end part which forms the hardening zone, where the latter is arranged so that under pressure load it can be moved in the longitudinal direction to a limited extent in relation to the former and has a wire discharge end which is sufficiently narrowed so that a back pressure is formed in the material column inside the chamber.

Selv om uttrykket herdesonens endeparti eller tilsvarende er benyttet ovenfor, skal det fremheves at dette endeparti ik-ke behøver å bli benyttet for å herde ma-terialet inne i seg, ihvis dette ikke er øn-skelig. Betegnelsen er bare benyttet for å forenkle beskrivelsen, da endepartiet van-ligvis vil bli benyttet for dette formål. Even if the expression end part of the hardening zone or equivalent is used above, it must be emphasized that this end part does not need to be used to harden the material inside, if this is not desirable. The designation is only used to simplify the description, as the end portion will usually be used for this purpose.

I en for øyeblikket foretrukket utfør-elsesform er klemvalsene av rustfritt stål med en diameter 1,5 cm (5/8"), og veggene i kammeret er av verktøystål. Klemvalsene er anbrakt i avstand fra hverandre slik at deres periferier er noen tusendels cm fra hverandre. Det indre tverrsnitt av stuke-kammeret er i det vesentlige jevnt rektangulært over hele dets lengde, selv om tverr-snittsarealet i herdesonens endeparti er litt større enn tverrsnittet av krusesonens endeparti. In a currently preferred embodiment, the pinch rollers are of stainless steel with a diameter of 1.5 cm (5/8") and the walls of the chamber are of tool steel. The pinch rollers are spaced so that their peripheries are a few thousandths of a cm apart.The internal cross-section of the stucco chamber is substantially uniformly rectangular over its entire length, although the cross-sectional area of the end portion of the curing zone is slightly greater than the cross-section of the end portion of the crucible zone.

Veggene i krusesonens endeparti består av plane front- og toakvegger som ved top-pen av sonen er anbrakt noen få tusendels tommer fra klemvalsenes sider, og sideveg-ger i form av blad hvis tilformede ender er anbrakt tett inntil klemvalsenes periferier. Bladenes andre ender er nedskåret til tyn-ne strimler som passer inn i munningen av herdesonens endeparti. The walls in the end part of the mug zone consist of flat front and two walls which at the top of the zone are placed a few thousandths of an inch from the sides of the pinch rollers, and side walls in the form of leaves whose shaped ends are placed close to the peripheries of the pinch rollers. The other ends of the leaves are cut into thin strips that fit into the mouth of the end part of the curing zone.

Herdesonens endeparti, hvis lengde er fortrinnsvis større enn lengden av krusesonens endeparti, er anordnet på enkle pa-rallellfjær strimmelfester så det kan innta forskjellige stillinger i forhold til og i nær avstand fra krusesonens endepartier, av-hengig av mengden av trådmateriale inne i trykk-kammeret. Det er videre belastet med en fast vekt som forsøker å presse det mot krusekammeret. Denne faste vektbe-lastning som omfatter en motvekt og en mottrykksvekt når kruseretningen peker nedover, er ansvarlig for konstant kontroll av krusemottrykket i krusesonen. Således vil små endringer i mengden av trådmateriale inne i trykk-kammeret ikke føre til endringer i mottrykket, og følgelig ikke til endringer i den type tekstureringer som innføres, fordi slike endringer vil "bli etter-fulgt av små justeringer eller bevegelser av herdesonens endeparti, mot eller bort fra krusesonens endeparti, uten endringer i trykket som utøves på tråden inne i krusesonen. The end part of the hardening zone, whose length is preferably greater than the length of the end part of the cupping zone, is arranged on simple parallel spring strip mounts so that it can take different positions in relation to and at a close distance from the end parts of the cupping zone, depending on the amount of wire material inside the press the chamber. It is further loaded with a fixed weight which tries to press it against the mug chamber. This fixed weight load, which comprises a counterweight and a counter-pressure weight when the cup direction points downwards, is responsible for constant control of the cup counter-pressure in the cup zone. Thus, small changes in the amount of wire material inside the pressure chamber will not lead to changes in the back pressure, and consequently not to changes in the type of texturing that is introduced, because such changes will "be followed by small adjustments or movements of the end part of the hardening zone, towards or away from the end of the cup zone, without changes in the pressure exerted on the thread inside the cup zone.

I stedet for å være fjæropphengt kan imidlertid herdesonens endeparti være anordnet på føringsstenger for ren vertikal bevegelse i forhold til krusesonens endeparti og en vekt tilført som beskrevet ovenfor. Instead of being spring-suspended, however, the end part of the hardening zone can be arranged on guide rods for pure vertical movement in relation to the end part of the mug zone and a weight added as described above.

Trådutmatningsenden til herdesonens endeparti er innsnevret J. eks. av en klaff som er dannet ved enden av front- eller bakveggen i endepartiet, ihvilken klaff er rettet innover mot den motstående vegg og festet i en bestemt stilling. Alternativt kan selve front- eller bakveggen være slik kon-struert at deres ender strekker seg innover på denne måte. Fordelene med en klaff er imidlertid at mengden eller utstrekningen av dens innoverrettethet, dvs. den vinkel som den inntar i forhold til front- eller bakveggens lengderetning kan innstilles for The wire output end of the hardening zone's end part is narrowed J. e.g. of a flap formed at the end of the front or rear wall in the end portion, which flap is directed inwards towards the opposite wall and fixed in a specific position. Alternatively, the front or back wall itself can be constructed in such a way that their ends extend inwards in this way. The advantages of a flap, however, is that the amount or extent of its inward direction, i.e. the angle it takes in relation to the longitudinal direction of the front or rear wall can be set for

å gi optimalt resultat i forbindelse med de forskj ellige tekstureringsprosesser. to give optimal results in connection with the various texturing processes.

Veggene eller noen av veggene i herde-sonenis endeparti kan oppvarmes f. eks. ved hjelp av elektriske motstandselementer over det hele, eller over deler av deres lengde. Hele endepartiet av herdesonen, eller den del som er oppvarmet, kan være inn-bygget i en varmekappe som inneholder varmeisolerende materiale. The walls or some of the walls in the end part of the hardening zone can be heated, e.g. by means of electrical resistance elements throughout, or over part of, their length. The entire end part of the curing zone, or the part that is heated, can be built into a heating jacket that contains heat-insulating material.

Temperaturen i herdesonen kan regu-leres ved hjelp av termostater til den nød-vendige temperatur. The temperature in the curing zone can be regulated using thermostats to the required temperature.
