The exploration of the oceans, lakes and clusters of the world, in particular the great depths of such bodies of water, was of vital importance in the past. However, it is in fact impossible to have full surveillance and coverage by direct human observation on the spot for all practical and imposing tasks, even if only a small fraction of the vast amount to be. area to be explored. The pole of this limitation is the extensive use of electronic detection and muting devices, the use of sonar equipment and television cameras. By far the largest part of this electronic monitoring and recording is carried out by humans from pilot ships or commandoscibodies that float underwater either on the surface of the water or in the immediate vicinity of this surface and use the probes that are pulled by the ships or floats Enlargement of the detection area or »increase in the extent of the recorded data, increased intensity was applied to the development of faster and more easily feasible detection methods, with the particular aim of providing housings or probes that record detection and detection devices ₉ underwater with the highest degree of stability with comparatively move at high speeds and in great water depths. can. An approach to this set goal was achieved through the development of underwater sands with self-propelled and maneuverable training, which no longer

have to be pulled behind a ship moving on the surface of the water.

In the implementation of this proposal, however, difficulties have arisen because the numerous different available streamlined cables mainly intended as tow cables for pulling underwater bodies are and not for facilities that may travel at higher speeds and at different speeds from the ship Directions are moved are appropriate. The experience with the known cables, and also with cables, the one have the following disadvantages of these cables:

There are large losses due to turbulence in the flow, which, even with towing probes, not only reduce the maximum speed, which can be achieved, but often also impair the reception and transmission of signals or obstruct, because stability is not achieved, i.e. the cable tends to become tangled and even to twist.

Although other factors may obviously be decisive, it is believed that the main cause of these disadvantages can be seen in the structural design of the known cables. The well-known cables are located nearby

the nose of the streamline profile an elongated support element in the form of a standard wire rope made of stranded and twisted wire strands, which has a circular cross-section and to which the additional elements required to create the streamline cross-section are loose% ie pivotable or rotatable. Examples of such known cable constructions can be found in TJ.S. Patents 2,597,957, 2,435,956, 3,060,886, 3,176,646 and 3,304,364. In these known cables, the wire rope is characterized by a relatively high torsional rigidity and it has the mechanical properties of a carrier with a circular cross-section, the longitudinal axis and the axis of symmetry as well as the torsion axis running through the center of gravity of the cross-sectional area of the cable. As a result, the torsion axis of the cable is at a distance from the nose of the towing cable which is at least as large as the radius of the wire rope. The term "torsion ^{axis w} (shear center) is used at this point in accordance with the designations of mechanics and strength theory as the intersection of the horizontal axis or axis of symmetry of the cross-section of a girder with the line of action of a perpendicular load that is exerted on the girder that no twisting of the same occurs.

At the same time, the relationship between the geometry of the streamlined design and the arrangement of the supporting part leads

the well-known tow cable to the fact that the pressure point of the Streamline cross-section of the overall combination relatively close, where the axis of the wire rope or drag part lies. Here becomes the term "pressure point" in accordance with the terms from aerodynamics or hydrodynamics used and denotes that point on a wing at which the resultant is aerodynamic lift and drag intersects with the wing chord. (Under the wing chord the straight line that extends from the wing nose to the drag wing trailing edge is understood here. Because of these geometric relationships, the size of the correction forces that are transferred to the known cables can be relatively small, limited by the small distance between the pressure point and the torsion axis. In addition, the cables known to date are generally characterized by a relatively high drag coefficient marked in the order of 0.1 and more. This high drag coefficient results on the one hand from the nature of the cable materials used, on the other hand from the cable shapes or profiles. The higher the The flow resistance, the greater the turbulence that arises when such a cable is moved through water. However, it is all the lower Immersion depth or water depth that can be reached with a cable of a given length. It is even at relatively low levels Towing speeds relatively low, while at higher speeds about a speed of

^L 909824/0995 "" ^J.

20 knots barely acceptable depths can be reached.

It thus appears obvious that the combination effect of the factors mentioned, i.e. the disadvantageous physical Properties on the one hand and the geometric relationships that interact with them, namely the arrangement of the Torsion axis in relatively close proximity to the pressure point Flow profile leads to the hydrodynamic instability of the known towing or connecting cables.

The invention is based on the object of avoiding the described disadvantages of the known cables.

To solve the aforementioned problem, the cable mentioned in the introduction is characterized according to the invention in that the Support part arranged in the region of the cable cross-section lying along the front third of the wing chord and formed with less flexibility than the remaining part of the wing cross-section, but opposite Relative movements between the two parts is firmly connected to the more flexible remaining part. and at essentially U-shaped cross-sectional shape one in the direction of the wing trailing edge has open recess, and that the torsion axis of the support part in the immediate vicinity of the wing nose of the cable cross-section and arranged at a considerably greater distance from the pressure point of the airfoil is as the center of gravity of the supporting part cross-section.

With a cable formed in the aforementioned manner Flow profile are the flaws and disadvantages of the known Avoided cables, so that this is not only used to guide trailing probes, but also to connect or as Pilot cables for underwater probes that are maneuverable and with Are self-propelled, is usable. The shape of the new cable makes it possible to work at the highest speeds and enables the greatest depths to be reached and a maximum of stability is achieved.

Viewed generally, the cable designed according to the invention has an outer circumference, the contours of which have a cross section surrounded, which has the shape of a [airfoil, which in turn is designed so that the pressure point in the immediate Neighborhood of the wing chord quarter as seen from the nose. The front part of the cross section beeteht either completely from a support part or has such a support part, which is essentially U-shaped Cross-sectional shape and lying between the legs of the U-shape open towards the rear edge of the airfoil profile Channel has a much lower flexibility than the other parts of the cable. This shape leads to the fact that the torsion axis of the support part or the front part of the cable cross-section considerably in the direction of the wing nose Center of gravity of the supporting part cross-section removed and at the same time in the immediate vicinity of the nose of the aerofoil profile-like Cable cross-section lies. The remnant part or rear part

- Fides cross-section, which at the rear end surfaces of the support part is attached or is connected to the front part, which contains the support part, and as a result due to the configuration described is attached to the end faces of the legs of the U-shape on both sides of the channel, has the shape of a wing tail or tail, which has an approximately three-cornered shape and is much more flexible is designed as the support part or front part. The support part is preferably made of high-strength (high modulus) threads, for example Glass fibers, made cast in a resin mold such as epoxy or epoxy-polyurethane resin are. The result is a specific weight in the order of magnitude of approximately 1.25 - 2.25, with the most advantageous values are in the range of about 1.9. The remaining part or rear part of the airfoil-like cable cross-section is preferred made of isotactic foam, such as the hardened end product a liquid polyether-polyurethane compound with small or glass microspheres, the latter being available under the trade name "Microballoons". It results A specific weight in the order of magnitude of 0.4-0.8, with the most advantageous values in the range between 0.5 and 0.75. The special values of the specific weights of the cable components of the new cable lead to that the cable as a whole body has a specific weight that is relatively close to the floating or floating point for Water is, i.e. in the order of magnitude between 1.2 - 1.4, but advantageously not above 1.25. Included

909824/0995

the focus of the cable either directly in the pressure point of the airfoil profile or at a short distance ver this pressure point. The support part and the remaining part of the flow profile-like cable are integrally or non-detachably combined and therefore together have a streamlined smooth outer contour that is not interrupted by anything, so that an advantageously low flow resistance coefficient is also obtained.

In the one located between the legs of the U-shape of the supporting part Channel is an electrical conductor, designed as a main or power cable, inserted. He serves in addition, the electrical energy to move the underwater probe to power the electronic equipment and devices and the like. This electrical conductor is expediently designed as a stranded wire or a spun conductor and designed so that it not only has adequate flexibility and the required ductility, but In addition, it also has the necessary electrical properties to perform its tasks as an energy and power transmitter to meet. The remaining cross-section of the channel, which is not occupied by the electrical conductor, is expediently taken by a polyurethane compound not provided with filler, which is introduced into the channel became. This polyurethane compound is selected to have an adequately high tensile strength to be used as

to serve electrical insulation for the electrical conductor. It is also ensured that the specific weight this insulating resin in the order of magnitude of 1.0-1.5, preferably around 1.1,} .lies, normally the insulating resin fill the channel at least "up to the level of the ends of the legs of the U-shape, although one goes beyond this limit Expansion of the insulating resin is also possible. Suitable electrical conductors as signal cables, which are also designed as strands or spun conductors and are used to Control commands or measurement data from the electronic equipment to transfer are housed in small hats that are in those pointing to the wing trailing edge of the Kafoel cross section End faces of the legs of the U-shape in the longitudinal direction of the cable. The electrical conductors introduced there also become an appropriate part of the insulating resin covered if the isolation ability or capacity the remainder or rear part of the airfoil-like Kabele seems to be insufficient for some reason.

Greatest diving depths a maximum of stability; because there is a greater distance between the torsion axis and the pressure point of the airfoil profile of the cable cross-section than could ever be achieved with known cables. Thereby exists but the possibility of using high feedback torques. Despite the specific training that cannot be dismantled, it can cables designed according to the invention but also suitably dimensioned Winches or drum are wound without the risk of permanent deformation. The new cable but can also be produced step by step ■ through molding processes are, so that a one-piece, in its length not articulated continuous cable of almost unlimited length can be realized up to several hundred or thousand meters.

The invention further provides a method for producing large one-piece lengths of a towing or connecting cable for underwater probes, the cross-section of which has the shape has a wing profile which is symmetrical to the wing chord. Identifies according to the invention This method is characterized by the fact that the front part of the airfoil, namely in the form of a strand-shaped support part with a U-cross section and more open to the wing trailing edge, produced between the legs of the U-shape lying recess and on the end faces of the free ends of the legs the U-shape with a remaining part forming the rear part of the airfoil profile to form a unitary body with the

The invention also provides an end coupling for the inventive formed cables, the streamlined cable body of which has a number of resin-soaked, high-strength threads, which are kept free of resin at at least one end. The end coupling for this cable is characterized according to the invention daduroh that it has an elongated outer housing which is cylindrical and over part of its length is provided over the remainder of the length conically shaped inner recess and receives an inner part, which on the middle its length cylindrical, however, at both ends is conically tapered, and that a clamping sleeve with a cylindrical outer shape and a conical inner recess is provided and between the cylinder part of the outer housing recess and one of the tapered ends of the inner part is arranged, the resin-free thread ends of the cable along the predominant part Part of the outer housing length into the gap between the Outer housing and the inner part are threaded, in the remaining area of the length of the outer building, however, between the inner

The drawings will now be discussed in detail. 1 shows the stern of a surface ship 30, for example an oceanographic research ship, floating on the surface of a body of water 31. A towing and / or connecting cable 35 is pulled off this winch drum 32 and lowered into the water via a pulley 34. The ends of this cable are provided with end couplings 36 (only one is drawn). These end couplings 36 are used to connect one end of the cable to the winch and the other to a submerged probe 37. Since the latter is not the subject of the present invention, it will not be discussed in detail either. It is only assumed for the purposes of the following description that the underwater probe is a device in which suitable underwater detection and / or measuring devices, for example sonar devices or television cameras, are accommodated within a housing. It should be emphasized, however, that the underwater probe 37 does not necessarily have to be provided with its own propulsion system ₉ but can just as well be designed as a towing probe.

^L 909824/0995 ^J.

As can be seen with great clarity from FIGS. 2, 3 and 4 lets, the towing and / or connecting cable designed according to the invention has an airfoil-like cross section and consists essentially of a front support part 38 and a non-detachably molded remainder or rear part 39. The support part 38 has a TJ cross-section, in which between the Legs of the TJ-3? Shape one in the longitudinal direction of the cable or support part extending channel 38a is formed. In the channel 38a, specifically in the section close to the nose of the airfoil, an electrical conductor 40 is embedded. This is the example of the cable shown a trunk or power cable. The cross-sectional area of the channel 38a not occupied by the electrical conductor 40 is filled with an insulating body 41, which has electrically insulating properties and which is in the cross section of the Channel 38a extends up to the plane at which the support part 30 and the remainder part 39 abut one another. The supporting part 38 is on the rear end faces of the legs of the U-shape of the Cross-section with a further pair of recesses, namely with grooves 42, which are also provided over the entire Extend the length of the cable and serve to accommodate further electrical conductors 43, which are for example Signal transmission cable can act. In the embodiment described in Pig. 2 are electrical Conductor 43 isolated from one another exclusively by the remainder or rear part 39 of the cable. The insulating body can however, also one with the reference numeral 41a in Pig. 3 shown

-20- ^L 909824/0995 ^J

Have a modified form for a cable 35a. Also in Pig. 4 a similar modified form of the cable 35b can be seen. The common feature of these shapes is the cable 35b in that the insulating body 41a or 41b in the cable 35a (FIG. 3) or 35b (FIG. 4) extends beyond the plane, at which the support part 38 and the rear part 39 abut one another. This creates a cable shape at which one and the same insulating body is used, the conductor 40 located in the channel 38a as well as the other conductors at the same time To cover conductor 43 insulating. Especially the one in Fig. 4 Shown shape of the cable 35b, in particular the insulating body 41b, leads to the additional advantage that in the Channel 38a can be accommodated much larger conductor cross-sections than in the other embodiments without as a result, impairment or weakening of the insulation would have to be accepted. On the other hand, it is possible, a particularly strong and high-quality insulation for an electrical conductor with a normal or small cross-section to be used if deemed necessary.

The support part 38 of the cable shown in the figures consists essentially of a mass of continuous cables in the longitudinal direction oriented threads 38 », which have a high stiffness, in particular strength, such as, for example Glass fibers or threads, and which are wrapped in a suitable binder or resin, such as epoxy resin or epoxy- Polyurethane resin, embedded or at least with one of the

It is obvious that the design of the drag part, namely, with regard to the proportions of the highly rigid or strong threads and the binding resin, primarily a puncture is the maximum desired or calculated load capacity of the cable and the tensile strength of the threads used, (In detail, the stated values result from the ratio of the dead load or construction load of the Cable to the tensile strength of the threads. Usually about 60-80 volumes are made up of fiberglass and the rest, that is 40-20 $ impregnation or binding resin used. At this There are gradations for most practical applications suitable values of the cable. In the example, a fiberglass from Owens-Oorning was used as the glass fibers Corporation manufactured fiberglass web, type designation S-9O1-15OG.

As already mentioned in the introduction, the support part 38 and the remaining part or rear part 39 are closed in the finished cable a unit inextricably combined, and they have the cross-sectional shape of an airfoil, which is symmetrical is designed for the wing chord. The cable is given this inseparable, uniform structure by the Mold treatments to be described below. You special shape of the wing profile, namely the one that proved to be the most advantageous, it represents.

back No. S-558, described on page 325 profile. In this airfoil profile, the hill chord is about 6 times as large long as the greatest height of the profile, so that there is a considerable reduction in the hydrodynamic drag coefficient compared to known cables. This extremely low hydrodynamic drag coefficient At the same time, the profile becomes more efficient through the IPorm treatment of the cable itself, in particular of the supporting part, and the use of appropriate appropriate materials. This makes it possible to make the outer surface of the cable as smooth as possible.

Reference is now made to FIG. 2Δ. In this Pigur is an embodiment of the new cable too. recognize at which the torsion axis is the furthest possible distance in the direction of the nose of the aerofoil profile rom pressure point of the aerofoil profile assumes. Below the torsion axis or the center of torsion of the support part of the new cable is understood to be the point around which the cable cross-section moves rotates in the event of torsion or rotation. This position of the torsion axis is due to the special cross-sectional shape of the supporting part achieved by the support part as a hollow beam B with a back W and two loops E, which form a channel C limit is considered. From the considerations of the fundamentals of the calculation of the strength of materials, in particular of carriers, it is known that in the case of a thin, hollow-body-like carrier, the torsion axis not with the center of gravity of the cross-beam

909824/0995 ^J.

Cut coincides, but is often outside the cross-section of the support and often even on the side facing the thighs outside of the back. The application of these teachings and findings to the cross-section of the support member of the cable shown in FIG. If the cross-sectional thickness T of the back ¥ is made sufficiently large and is chosen so that it makes up a considerable part of the cross-sectional length L of the beam, then it is possible to move the torsion axis from its theoretical position outside of the beam to the left, i.e. when viewed the 'Fig. 2 to relocate within the geometric dimensions of the carrier. The exact point of the position of the torsion axis ultimately depends on the strength values of the back and the legs of the hollow profile.

For the purposes of the inventively designed Kabels found that the best results then broke can be achieved if the cross-section or Fitigelsehneη-length of the support part formed from fibers and binder hair (i.e. the length of the distance L of the support B) is expedient in size between about $ 30-40, preferably one Third, the total wing chord length of the airfoil cross-section of the cable. Below the wing chord length is seen the stretch that extends from the right to the left

End of the profile according to Pig. 2, 3 and 4 extends. It is also advantageous if the chord length of the supporting part from the nose of the airfoil cross-section of the cable to the bottom of the channel 3Ba (this is the size of the distance T. of carrier B) on the order of about $ 30-40, preferably on the order of a third of the total flight tendon length of the supporting part. In general, the distance L should be three times as large as the distance T. Since that Ratio of the maximum profile height of the cable to the length of the bowstring should preferably move in the order of magnitude of 1: 6, the result is the maximum cross-sectional width of the Support part (distance D of the carrier B), which is also normally auoh the width at the open end of the channel in the On the order of about 45-55, preferably about $ 50, the Total wing chord length of the supporting part; i.e. essentially that the distance Ii should be about twice as large as the distance D. target.

If the cable is constructed in the aforementioned manner, the entire cable results in a wing chord length, for example of the cross section of about 7.5 cm. It was found that the pressure point of the airfoil and the Focus is on a quarter of the wing chord, measured from the wing nose, while the torsion axis runs in the immediate vicinity of the nose of the airfoil profile cross-section of the cable or even slightly in front of it this edge extends, but never more than a third

^L 909824/0995 ^J.

the wing length of the supporting part is removed from the nose in the direction of the trailing edge of the wing. That focus on this Wise resulting cable has an extremely low torsional stiffness and has a very low hydrodynamic Resistance coefficient and is also characterized by an almost neutral behavior towards sinking or buoyancy in the water. The result is a high stability of the cable, which is retained even when it is relatively moving through the water at high speeds. In addition, the cable, although it is due to the hollow body shape has a high flexural strength and although it is made of relatively heavy-duty fibers in hardened resin binder there is sufficient flexibility to allow the cable to be wound onto a winch drum without this a permanent setting of the cable would have to be feared, which would impair the stability. The cable can be wound on a winch drum with low loads if this, as for the use of fiber optic cables, usual, has a minimum drum diameter of 2.4 m. The cable is connected to the nose of the wing profile wound on the drum surface. The thread and fiber portions of the supporting part take up the whole Load on the cable.

The remainder or rear part 39 of the cable must, as is obviously understood, be a lot compared to the support part - Have greater flexibility, and it must be made of one material

It is preferably used a resin made of epoxy or Is composed of epoxy-polyurethane compounds. The application Similar or similar materials for the rest of the part result from observing the following regulations:

For the reasons already mentioned, the composition must the material intended to form the remaining or rear part of the cable have a specific weight, which is substantially below 1.0, preferably in the range of about 0.5. Palis so the resin used has a specific weight on the order of 1.0 or greater specific gravity, it must be added by adding a filler with a lower specific weight, roughly in the range of 0.3-0.4 »to a lower specific total weight to be brought. The puller used must of course be compatible with the resin molding used and in this can also be easily solved. It must not have any adverse or harmful effects on the malleability the resin compound exercise. The resin compound must remain soft and pliable in order to fill the porm cavities to facilitate. In addition, the filler used must have both to be resistant to water as well as to oil and at least to the resin and also a very high one Have compressive strength. As prepare from the foregoing

This requirement is optimally met by the conductor shown in FIGS. 2-4, which is a two-layer Ribbon strand is formed and in turn 6 individual strands of 0.05 x 0.46 cm cross-section are housed in each layer are. Such a strand of tape is available under the trade name "Alpha-PIachband 1251".

Head can serve. It is of course also possible to use a two-core conductor that provides suitable insulation for the Must possess both conductors in order to be aware of the conductivity of the surrounding To be independent of water.

The same considerations must also be made for the signal conductor 43. It is assumed, for example, that these conductors correspond in their electrical properties to at least a 20 or 50 copper wire and at the same time have a minimum ductility of at least 2.7 $ in the longitudinal direction, which must be possible without permanent mechanical deformation. It was also found here that braided and stranded conductors, such as, for example, the ^{flat-ribbon litz cable available under the trade name "Alpha-Piachband 1221 w"} , best meet these requirements.

The insulating body 41 (or 41a or 41b), which is provided for the cable constructed according to the invention, must have at least a high breakdown voltage strength. Its specific weight should be as close as possible to the value 1.2 and not be outside the values 1.0 - 1.2. A sufficiently high tensile strength is also required in order to achieve the greatest possible resistance to tearing, with elongations of 5 $> having to be withstood without damage.

To continuously unlimited amounts of this cable, which is streamlined in cross section, with the aforementioned Establishing properties is proceeded in a manner discussed below with reference to Figures 6-29 will.

In station I facilities are provided that effect the resin impregnation of the thread bundle, which ultimately represents the supporting element of the supporting part.

For the purposes of this description it will be assumed ₉ that the manufacture of the new cable is in progress, and that the Pig. 3 shown cable 35a is manufactured. A completely finished cable part 35a is shown in FIGS. 6, 26, 27 and 29 as extending beyond the exit end of production stage V. The other parts of the cable are in earlier stages of completion and go through the individual production stages of the production line 44 It should be emphasized that each production stage, that is to say each production facility of the production line 44 that forms a production device, always only ever has one Cable part processed during a certain period of time, and that each cable part is moved step-by-step through the device so that the end product results from step-by-step and step-by-step building.

The following are the individual production steps EU. explain:

Subsequently, or in the device 7, the completed one Cable moved in a manner to be described later and wound onto a take-up drum, not shown. In the Facility I, on the other hand, uses a suitable number of continuous, high-strength threads, for example GIa θ threads or woven glass fibers, withdrawn from a carrier, not shown, for feeding a plurality of threads or fibers and through a series of Combing and collecting rolls (not shown) out until a uniform multi-thread bundle or strand 45 results, (fig. 6 and 7). The assembled thread or fiber bundles, in which all individual threads or fibers run essentially parallel to one another, then runs through the upper region a channel 46 (FIG. 8) which is essentially circular in its circumference and of one correspondingly in cross section designed circumferential groove of a roller 47 is limited. Within this channel 46, the thread or fiber bundle is predetermined Wise compressed and compressed within the cross-section of the channel on the one hand, namely its lower area, and the outer circumference of an upper roller 48, which engages easily sliding between the flanges of the roller 47, is limited.

When the thread or fiber bundle 45 reaches this channel, it is impregnated in the required manner with a resin binder 49 which is applied to the bundle from a suitable reservoir 50 at the entry end of the rollers 47 and 48. ^L 909824/0995 " ⁵⁶ ~ ^J

The amount of binder abandoned is expediently chosen so that the setting and maintenance of a Certain supply 51 results, which is necessary to the proper impregnation of the pad or fiber bundle guarantee. Excess resin can be discharged via a suitable discharge device 53 which, for example, extends into the groove 46 the roller 47 protrudes, taken up and removed. This device is below the thread or fiber bundle 45 to arrange. During the compression of the thread or fiber bundle between the rollers 47 and 48 within the channel 46, the fiber bundle is converted into a cross-sectional shape which 8 and denoted by the reference numeral 45a. After leaving the channel 46 or the gap between the However, rollers 47 and 48 tend to swell the thread or fiber bundle 45a again, and it takes the one shown in FIG and cross-sectional shape provided with the reference numeral 45b.

In FIG. 7, a feed device 49 for the impregnating resin is shown at the same time, which, for example, is simple Way can be formed by a tiltable container that is operated by hand or tilted in a mechanical manner. It however, it is just as possible that other devices can serve the same purpose, such as a mixing head, the one with a number of outlet openings or mouths is provided. However, with such considerations it is too. take into account that almost all for the impregnation of the thread or Fiber bundles in question have resin binders only very short consumption times and are therefore normally off

Expedient reasons are only used in small amounts or be prepared. A continuous feed is therefore less too. recommend, especially with regard to to the fact that the manufacturing process of the cable takes place in successive steps which it requires make to move the cable as a unit periodically interrupted.

But before the previously impregnated pad or fiber bundle 45b enters the device II of the manufacturing device 44, it is initially through a pair of spaced-apart cones 54 (Pig. 6, 10 and 11) and thereby from the in Pig. 9 is converted into a more elongated cross-sectional shape 45c (see Fig. 11). Even after Passing the rollers 54, the impregnated pad or fiber bundle again tends to swell slightly in cross section, so that again one with the reference numeral 45d in Pig. 12 shown oval cross-sectional shape results.

The impregnated pad or fiber bundle 45d now enters an elongated, upwardly open channel 55 (Pig. 10 and 13), which the lower half 56 of a molding and hardening press 57 forms. The channel 55 extends over the entire length of the press, for example over a length of 3.60 m, and has a rounded base, the cross-sectional contour of which corresponds to the contour of the front part of the cable body should own in the final state. The upper part of the channel 55 is made up of straight walls that run in the perpendicular direction.

-38-

909824/0995 ^J.

fertilize limited, between which a height-adjustable upper Molded part 58 fits tightly sliding into it. This upper molding 58 is attached to a Querhau.pt 59, which also extends over the entire length of the press 57. The order of the two compression molding halves is chosen so that when the press or mold (Pig.14) is closed, the gap between the lower edge of the upper mold part 58 and the lower area of the channel 55, corresponds exactly to the cross-sectional shape, both in shape and dimensions, which the support part of the cable should have in the final state. There is at most a deviation from the final dimensions of the supporting part in the Kind of possible that the value of the wing chord length of the supporting part determined by the channel shape is greater than for the final dimensions of the supporting part is required.

As can be seen from FIGS. 6 and 10, a squeegee roller 60 is provided, which passes through in a reciprocating path the upper region of the channel 55 is guided. Your starting position is in broken lines in Pig. 10 shown, namely it lies outside the press at the exit end of the supporting part of the cable body (when viewing the Fig ^. 10 right hand of the! Molding press). The squeeze roller moves from this starting or starting position to the left when looking at the figure and then back to the starting position return. The purpose of this movement of the roller is to remove excess resin from the pad or fiber bundle to remove and already a

-39- ^L 909824/0995

To bring about pre-compression of the bundle, which makes it easier to close the compression molding press. The squeezed-out excess resin runs off via a discharge funnel 61 from the molding press or via another line into a container 62 and can be removed there. The mold halves 56 and 58 of the press are provided with heating devices 63 and 64, for example electrical resistance heating devices, which do not extend the entire length of the press. Instead of electrical resistance heating devices, it is also possible to use flowing heat transfer media which are passed through appropriate pipelines. In the case of a 3 ₅ 6O m long press, this does not mean about 0.30 m from each end of the press.

As soon as the squeeze roller has finished its working stroke and has returned to the starting point, it becomes the crosshead 59 lowered, to close the press cavity and the to compress the resin-impregnated thread or fiber bundle until it assumes the ribbon cross-sectional shape 45e in FIG. At the same time the resin binder is cured. At the same time, however, the one that has hardened in the previous work cycle rests Part of the thread or fiber bundle section, which is hereinafter referred to as the support part blank 45f and in Fig. 15 is shown outside the press in a guide trough 65, which has the task of any destruction or undesirable deformations of the still warm blank to avoid. This trough can end with a corresponding gi] if necessary Pipelines for a heat transfer medium or a cooling

-40-

909824/0 3 95 ^J

be provided so that a cooling of the supporting part blank of the cable can be carried out. It should be noted that a small section of the previously cured support part tubing within the unheated section of the molding press must remain, which at the same time serves to close the relevant end of the lOrmhohlraumes during the curing process. As soon as the curing process is finished, the press cavity becomes the preparation for the next movement step of the cable open.

Simultaneously with the work step already described, the previously cured support part blank 45f is treated in the device III of the device 44 in order to create hats for the insertion of electrical conductors and a channel for the insertion of a further conductor which, for example, forms a main cable. To. For this purpose, a frame 76, preferably in the form of a support device (S ¹ Ig. 16 and 17), is movably arranged on rails 67 arranged on both sides of the trough 65. This support frame accommodates a drive motor 68 which is connected via suitable gear connections, for example a drive belt 69, to pulleys 70, 71 and 72, which in turn are arranged on shafts 73, 74 and 75 which are rotatable in the frame of the support frame 66 are stored and extend transversely to the length of the trough 65. A pair of grinding disks 76 are arranged on the shaft 75, which are used to grind out the two longitudinal grooves provided on the end face in the support part, while the shaft 74 carries a grinding disk 77, which is between the legs

the U-iOrm of the supporting part cross-section lying central channel grinds out. The shaft 75 carries a relatively wide grinding and polishing wheel 7β, which is slightly "wider than the width of the Support part blank 45f is formed.

When the support frame 66 is along the trough 65 when viewed the iig. 16 is moved from right to left, then two outer longitudinal grooves and a central longitudinal channel are created or worked out in the upwardly facing surface of the supporting part blank 45f. At the same time, the cross-section of the supporting part is also ground to size, in such a way that all excess material is removed until the height of the supporting part cross-section when looking at the pig. 16 corresponds to the desired end wing chord length of the supporting part. The one on this Way finished supporting part blank 45g is in the 3Pig. 18 shown and forms the finished support part. It is this one Point to emphasize that a traversing movement of the grinding device is not required, but that instead also a stationary set of grinding wheels can be used to make the required groove and channel to. generate and remove the excess material from the supporting part blank. These stationary sole devices work then in such a way that the necessary relative movements between grinding wheels during the movement steps of the cable and supporting part blank are executed. However, it should be mentioned that the movable arrangement of the grinding device has the advantage that the support frame of the grinding device can perform several working strokes, while the

-42-

909824/0995 ^J.

ser working strokes only removes small amounts of material., so that a more precise and precise processing and control of the work process is possible.

In the course of the gradual advancement of the cable that see is in production, the support part 45g is guided along under an insertion device 79, which is inserted into the Pig. 16 and 19 can be seen. It has a frame 79a on which large Yorratsrolle or other feed directions 80 for one electrical conductors 40 (main or power cables) and a pair of smaller supply rolls 81 for the electrical conductors (Signal cable) are held. After all, pu and are Press rollers or wheels 82 and 83 are provided. The support part passed through the insertion device 79 shows Passing this device on the shape shown in Fig. 20 by the reference numeral 45h.

Before the support part 45h of the cable provided with electrical conductors is produced in this way in the next manufacturing facility IV of the device 44 is transferred, it is first under a set of nozzles 84 (Pig. 6, 21 and 22) guided along, from which electrically insulating resin for electrical insulation of the conductors is applied to the support part 45h. With the working method described here in the example becomes the one in Pig. 3 produced insulating body 41a. For this purpose, a sufficiently large amount of the Resin can be applied in order to fill both the free cross-sectional parts of the duct and the lute of the

-43-

^L 909824/0995 ^J.

lings to ensure as well as a certain application on the surface above, to the side outside the boundary edges of the hats that accommodate the ladder 43, to reach. The result is a supporting part blank 45i, which is described in Pig. 22 is shown. Instead, it could also be As is easy to see, an insulating body 41b can be produced in accordance with Pig. 4. The use of the two outer nozzles 84 is not required if an insulating body 41 according to Pig.2 is formed.

Immediately after passing through the nozzles 84, the supporting part blank 45i coated with insulating resin becomes an elongated one Channel 85 of a lower mold half 86 of a hardening and molding press 87 transferred. The cavity of this hardness and Compression press is closed by lowering an upper standard part 88 (Pig.23). He is using suitable heating equipment 89 optionally with pipelines for a fluid heating medium or with electrical resistance heating devices provided to cure the insulating resin of the insulating body 41a. The supporting part state created in this way supports this Numeral 45j and is in Pig. 23 shown.

The support part 455 produced during the previous work cycle according to Pig. 23 is in the following moving step of the Cable is transferred to a press 90 (Pig. 6, 21, 24 and 25), which is part of the production facility IV of the device 44 forms.

! ig. 24 and denoted by the reference numeral 45k The supporting part is used. An upper two-piece mold half that consists of the sections 93 and 94 consists is arranged movably with respect to the lower mold half 91, namely in the Meise that the two farm halves sideways, across the cable from each other away and towards each other. can be moved. The movement of the mold half sections 93 and 94, which are in the manner of jaws Toll pulls, is made by suitable drive devices, for example hydraulic or pneumatic working cylinders 95 and 96. The upper mold half sections 93 and 94 are in tight conductive contact with one end the adjacent end of the upper mold half 88 of the press 87 (Figs. 6 and 21) while at the other end they contact a pair of cable clamping members 97 and 98 (Figs. 6, 21 and 25) which are driven by suitable drive devices, for example hydraulic or pneumatic working cylinders 99 and 100, are operated. The inner surfaces of the mold cavity cross-sections as well as the cable clamping elements are shaped so that they result in cavities in a completely closed position, the cross-sections of which exactly match the shapes and dimensions of the desired airfoil profile cross section of the cable. One or more feed nozzles or straighteners are above the dividing line between the two sections 93 and 94 the upper mold half arranged (Fig. ό, 21 and 24).

When this state is reached, i.e. when the one before prepared fragile part 453 in the lower mold half 91 of the Press 90 is added and when the press 87 by lowering

The working cylinders 95 and 96 are then actuated to bring the sections 93 and 94 of the upper standard part against one another. move until they get the in the Jig. 24 assume the position shown in solid lines. As a result, the resin mass 102 is converted into the desired permeability and at the same time also hardened, whereby they are also connected to the support part 45k in the course of this process to form a unitary body will. Suitable electrical or working with a flow medium Heating devices 103 are provided in the sections 93 and 94 of the upper mold half to this curing and To support porming. During this process, the Pormhohlraum on one .Seite through the Pormobteil 88 of the Press 87 closed. At the other end, the clamping elements are used 97 and 98, which must be tightly closed during this operation and the end of the previously made and hardened residual or cable cross-section rear part 102 in Pig. 25 enclose yourself while still having a certain Part of the supporting part cross-section 45m in Pig. 25 extend.

This rests during the rotation of the clamping elements 97 and 98 in a support trough or a support channel 104. The result is that the inner cavity is thus closed off on all sides at the outlet end, the hardened part 1O2a-45m that has already been manufactured serves as a closure. A leak of the Resin 102 from the mold is therefore surely and effectively prevented.

The movement of the already mentioned several times in the individual in the stages of manufacture as well as completed cables 35a takes place in the direction of a supply or receiving drum in steps intermittently, according to the work cycle of the individual production facilities I - IY. These Step movement is effected by a friction drive 105 (Pig. 6, 26 and 27)> which is part of the manufacturing facility Y of the device 44 forms. In a preferred embodiment, the friction drive 105 has a pair of endless drive belts and 107, which act with a high degree of frictional engagement on the opposing surfaces of the finished cable 35a. To achieve the high frictional engagement, the endless belts 106 and 107 can be used as rubber belts with toothed or in some other way be formed roughened surfaces. The friction belts are over suitable rollers 108 and 109, which are in a frame 110 are rotatably mounted, guided. They will go through together suitable gear connections driven by a motor 111, which is arranged on the frame.

As soon as in the course of the individual described and expiring at the same time If operations open the presses 57, 87 and 90 and the clamping elements 97 and 98, the drive motor 111 is switched on and the cable is moved one specific step further in order to be able to carry out a further work cycle. at This is then the cable sections located in the individual stages in the production facilities I - V by one Manufacturing step has been moved. This process is repeated until a cable of the desired type is integrated into one piece Length results.

In doing so, special care must be taken, to avoid any damage to these unirapregnated lasers or avoid pendants until the end couplings are attached. The same doorway is at the end of the desired one Cable required. It should be noted, that at the beginning of the Cable manufacturing process also a sufficiently large length of the electrical conductors 40 and 43 over the ends of the Cable body 35 or 35a or 35b must protrude freely so that The ladder is guided through the couplings and with the corresponding electrical equipment on the research ship or can be connected in the submerged probe.

Reference is now made to Figures 5 and 5A, in which a decoupling 36 is shown, which for the invention trained cable is suitable. It consists of an outer housing 116, which is hollow and made of stainless steel. It is designed to accommodate a molded Piberglas inner body 117 and a clamping sleeve 118 made of stainless steel suitable. The outer housing is essentially cylindrical over most of its length. At one end it is provided with an external thread 119, which a Terbinding with the underwater probe or an equivalent Connection element of the winch drum permitted. Inside the Outer housing is a substantially cylindrical "recess 120, which, however, is conical at the end 12Oa

I *. of the outer housing 116 ^. The clamping sleeve 118 has a cylindrical outer surface and a conically tapered inner recess 121. Seen in axial section, this results in a wedge-shaped cross section of the clamping sleeve. As is particularly evident from the Pig. 5A, the inner part 117 is provided with a relatively wide, in cross section rectangular and axially extending recess 122 and two further in cross section also rectangular, but smaller, also in the axial direction bores or recesses 123 which run parallel to recess 122.

In order to achieve the streamlined cross-section of the cable mi S To connect the end coupling 36, the non-impregnated end region of the thread bundle 45 is passed through the outer housing 116 and at the same time placed around the not yet introduced inner part 117. The pasers or pads are made in sections in a plurality of circumferential plies and layers, based on the radial direction, divided by pre-impregnated extensive layers of a Q-lasgewebes 124 (see Fig. 5E) interposed so that the interlayer resistance values are as high as possible can be achieved between the pasers in the coupling. At the same time, however, the head 40 and the two heads are also 43 guided through the recesses 122 and 123 of the inner part. Thereafter, the clamping sleeve 118 is placed over the threads and the glass fabric covers up to the inner part or the adjacent

Bart end 117b pushed. It uses an epoxy resin binder applied as an impregnation to the cables and the glass fabric located between the cable body and the coupling. The entire assembly is then drawn into the outer housing 116, until the position shown in Hg. 5 is reached. That part of the bundle of pasers or threads that is between the body of the cable and the coupling lies, can be wrapped with one or more layers of resin-impregnated glass fabric 125 (Jig. 5 and Fig. 5D) will. The cable and the coupling are then subjected to tensile stress acting in the longitudinal direction in order to create an interference fit of the assembly while the curing of the resin impregnant is being carried out. As a final step becomes a flexible resin streamlining body that preferably essentially coincides in its contours with the contours of the cable body itself on the portion of the Pads or easers formed between the finished cable body and the end coupling lies. This shaping of the streamline profile however, it is only required at the end of the cable that will be connected to the underwater probe during use target.

It is obvious that the design of the cable described above as an example, as well as its manufacture can be subjected to numerous variations and modifications. This applies both to the distribution of the load-bearing 3? Threads or fibers, but also, for example, for the methods and devices that are used. pre-condition is only that in the arrangement of the

-51- ^L '909824/0995 ^J

Threads or fibers, but also, for example, for the methods and devices that are used. Requirement is only that in the arrangement of the fibers or threads or bil- • tion of the support part a cross-sectional shape is generated which results in a support cross-section in which the torsion axis or the center of torsion of the cross-section of the finished cable at a considerably greater distance from the pressure center of the airfoil cross-section of the cable, specifically in the direction of its nose, is the center of gravity of the carrier or the cross section of the supporting part. This results, for example, in possible shapes in which the actual cross section of the supporting part has the shape of a thin-walled channel. It can only be ruled out that a relative movement occurs between the front cable part and the rest of the resin body, which is kept free of threads is. According to the invention, it is also possible, for example, to use preformed support parts and either convert them into one also to bring in pre-formed residual bodies or bodies formed in the course of the feeding process. (In this case there is a certain variation the working method required when inserting the ladder). Instead of the glass fibers or threads, however, others can also be used high-strength fibers, i.e. fibers with a high modulus of elasticity or large so-called Young-Iviodul, or threads with low separability, for example steel wires can be used. If metallic threads or fibers are used, it is necessary to to ensure that there is adequate electrical insulation between the electrical conductors and the metallic load-bearing Threads or fibers is guaranteed.
