Description

Die vorliegende Erfindung betrifft eine Verbindungsvorrichtung für Medien, insbesondere hydraulische Strömungsmedien, bestehend aus einem Anschlussteil aus Kunststoff mit mindestens einem Anschlussabschnitt mit einer Aufnahmeöffnung für ein rohrförmiges, mittels Laserstrahl zu verschweißendes Leitungsende.The The present invention relates to a connection device for Media, in particular hydraulic flow media consisting from a connecting part made of plastic with at least one connection section with a receiving opening for a tubular, to be welded by laser beam line end.

Die DE 10 2006 034 697 A1 beschreibt eine Kunststoffleitung mit einem direkt an ein Leitungsende angeschweißten Anschlussteil in Form eines Hydraulik-Winkelsteckers oder eines Kunststoffgehäuses eines sonstigen Hydraulikelementes. Für eine Verschweißung mittels Laserstrahl soll die Kunststoffleitung und/oder das Anschlussteil aus einem für Laserstrahlen transparenten Kunststoff bestehen, wobei zudem alle Bestandteile (Anschlussteil und Leitung) aus dem gleichen Kunststoffmaterial gebildet sein sollen. Die für Laserstrahlen transparente Ausgestaltung schließt aber bestimmte Applikationen aus, weil wegen der geforderten Lasertransparenz bestimmte Kunststoff-Anteile, wie Verstärkungsstoffe (z. B. Glas-/Kohlefasern) und Additive (z. B. Farbpigmente und insbesondere Ruß als UV-Schutz) nicht oder nur eingeschränkt vorgesehen werden können, weil derartige Anteile die Lasertransparenz dahingehend beeinflussen würden, dass das Material weniger oder gar nicht mehr lasertransparent wäre.The DE 10 2006 034 697 A1 describes a plastic line with a directly welded to a line end connector in the form of a hydraulic angle plug or a plastic housing of another hydraulic element. For welding by means of a laser beam, the plastic line and / or the connecting part should be made of a transparent plastic material for laser beams, wherein in addition all components (connecting part and line) should be formed from the same plastic material. However, the embodiment that is transparent for laser beams excludes certain applications because, because of the required laser transparency, certain plastic components such as reinforcing materials (eg glass / carbon fibers) and additives (eg color pigments and in particular carbon black as UV protection) do not or may be limited because such moieties would affect laser transparency to the extent that the material would be less or no longer laser transparent.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Verbindungsvorrichtung der genannten Art zu schaffen, mit der trotz der Möglichkeit der Schweißverbindung mittels Laserstrahlschweißen eine Auslegung des Anschlussteils für nahezu beliebige Applikationen möglich ist.Of the The present invention is based on the object, a connecting device of the kind mentioned, despite the possibility the welded joint by means of laser beam welding Design of the connection part for almost any application is possible.

Erfindungsgemäß wird dies durch die Merkmale des Anspruchs 1 erreicht. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention this is achieved by the features of claim 1. Advantageous embodiments The invention is the subject of the dependent claims.

Demnach besteht erfindungsgemäß das Anschlussteil aus mindestens zwei Komponenten mit unterschiedlichen Materialeigenschaften, wobei eine erste Komponente im Bereich des Anschlussabschnittes die Aufnahmeöffnung umschließt und aus einem für Laserstrahlen weitgehend transparenten Material besteht. Im übrigen Bereich des Anschlussteils kann die andere, zweite Komponente bezüglich ihrer Materialeigenschaften für praktisch beliebige, applikationsabhängige Erfordernisse ausgelegt sein, und zwar vorteilhafterweise unabhängig von ihrer Wirkung für Laserstrahlen. Dies bedeutet, dass die zweite Komponente insbesondere Laser absorbierend (nicht lasertransparent) ausgebildet sein kann. Dadurch kann die zweite Komponente beliebige, applikationsabhängige Material-Anteile enthalten, insbesondere beliebige Verstärkungsstoffe (z. B. Glas-/Kohlefasern) und/oder bestimmte, z. B. eigenschaftsverändernde Additive.Therefore According to the invention consists of the connection part at least two components with different material properties, wherein a first component in the region of the connection section enclosing the receiving opening and from a for Laser beams largely consists of transparent material. Furthermore Portion of the connector part may be the other, second component with regard to their Material properties for virtually any, application-dependent Be designed requirements, and advantageously independent of their effect for laser beams. This means that the second component in particular laser absorbing (not laser-transparent) can be trained. This allows the second component to Contain application-dependent material shares, in particular Any reinforcing materials (eg glass / carbon fibers) and / or certain, e.g. B. property-modifying additives.

B. at the end of a pipe or hose (fixed / formed) is. The line or the line end 8th may be circular or non-circular in cross-section, e.g. B. oval or polygonal, be formed.

Erfindungsgemäß besteht das Anschlussteil 2 aus mindestens zwei Komponenten K1, K2 mit unterschiedlichen Materialeigenschaften. Eine erste Komponente K1 umschließt im Bereich des Anschlussabschnittes 4 die Aufnahmeöffnung 6 und besteht aus einem für Laserstrahlen weitgehend transparenten Material. Die andere, zweite Komponente K2 kann aus einem Laserstrahlen absorbierenden Material bestehen, welches deshalb beliebige, je nach den applikationsabhängigen Erfordernissen ausgewählte Materialanteile enthalten kann. Vorzugsweise besteht die zweite Komponente K2 aus einem Polyamid, wobei dieser Basis-Kunststoff beispielsweise für die folgenden applikationsabhängigen Erfordernisse bestimmte, in Klammern genannte Materialanteile bzw. Zusatzstoffe aufweisen kann:

  • – Mechanische Festigkeit (Verstärkungsstoffe, insbesondere organische und/oder anorganische Werkstoffe, wie Fasern aus Glas, Kohlenstoff und/oder Flachs, Glaskügelchen, Glimmerplättchen), wobei die Auswahl der Zusatzstoffe in Abhängigkeit von folgenden geforderten Parametern getroffen wird: Festigkeit (Zug), Druckfestigkeit (Berstdrücke), Zähigkeit, Steifigkeit, Elastizität (beispielsweise bei Steinschlag), Härte

According to the invention, the connection part 2 from at least two components K1, K2 with different material properties. A first component K1 encloses in the region of the connection section 4 the receiving opening 6 and consists of a material which is largely transparent to laser beams. The other, second component K2 may consist of a laser-absorbing material, which may therefore contain any selected according to the application-dependent requirements material proportions. In front Preferably, the second component K2 consists of a polyamide, this base plastic may have, for example, for the following application-dependent requirements specific, called in parentheses material components or additives:
  • - Mechanical strength (reinforcing materials, in particular organic and / or inorganic materials, such as fibers of glass, carbon and / or flax, glass beads, mica flakes), the choice of additives is made depending on the following required parameters: strength (tensile), compressive strength (Bursting pressures), toughness, stiffness, elasticity (for example in the case of rockfall), hardness
  • - UV protection (soot, pigments, nano-pigments)
  • - Thermal stability (soot)

  • - Antistatic design (soot, particle pigments)
  • - Chemical resistance (carbon black, pigments, coatings) in particular for the management of fuels, oils and the like
  • - Reduction of flammability (bromine, phosphorus compounds)

Bezüglich der lasertransparenten Komponente K1 ist zusätzlich auch die Wandstärke zu berücksichtigen, weil die Laser-Transmission bei Durchstrahlung nach einer e-Funktion abnimmt. Hierbei gilt R + A + T = 100%, wobei R die Reflektivität, A die Absorption und T die Transmission bedeuten. Hierbei sollte die Auslegung jedenfalls so erfolgen, dass R kleiner 20% ist. Die radial gemessene Wandstärke der lasertransparenten Komponente K1 sollte vorzugsweise im Bereich von 1 mm bis maximal 5 mm liegen. Im Falle einer Faserverstärkung sollte der Faseranteil maximal etwa 30% betragen, und zwar in Abhängigkeit von der zu durchstrahlenden Materialdicke (z. B. bei 1 mm etwa 30% und bei 5 mm maximal 10% bis zu 0%). Demgegenüber kann die zweite Komponente K2 beliebige Faseranteile von z. B. 20% bis 60% enthalten.In terms of the laser-transparent component K1 is in addition also to consider the wall thickness, because the laser transmission when radiating after an e-function decreases. Here, R applies + A + T = 100%, where R is the reflectivity, A is the absorption and T is the transmission. In any case, the interpretation should be such that R is less than 20%. The radially measured wall thickness the laser-transparent component K1 should preferably be in the range from 1 mm to a maximum of 5 mm. In the case of a fiber reinforcement the fiber content should be at most about 30%, depending on of the material thickness to be irradiated (eg at 1 mm about 30% and at 5 mm maximum 10% up to 0%). In contrast, can the second component K2 arbitrary fiber content of z. B. 20% up 60% included.

In der in 1 veranschaulichten, bevorzugten Ausführung ist die an die lasertransparente Komponente K1 angrenzende Komponente K2 als Steckverbinderteil mit (mindestens) einem Steckerschaft 10 ausgebildet, und zwar beispielsweise wie in 1 dargestellt in Form eines Winkelsteckers. Alternativ oder aber zusätzlich zu dem Steckerschaft 10 kann auch mindestens eine Steckmuffe zum Einstecken eines Steckerschaftes eines weiteren Verbinderteils vorgesehen sein. Zudem ist auch eine Ausbildung als T-Stück, gerader Durchgangsverbinder, Verteiler oder beliebiges Winkelstück möglich.In the in 1 illustrated preferred embodiment is the adjacent to the laser-transparent component K1 component K2 as a connector part with (at least) a plug shank 10 trained, for example as in 1 shown in the form of an angle plug. Alternatively or in addition to the plug shank 10 it is also possible to provide at least one plug-in sleeve for inserting a plug shank of a further connector part. In addition, a training as T-piece, straight through connector, distributor or any angle piece is possible.

In vorteilhafter Ausgestaltung ist ein innerer Medienkanal 12 des Anschlussteils 2 über seine ganze Verlaufslänge hinweg bis zu einem inneren, einsteckseitigen Endbereich der Aufnahmeöffnung 6 für das Leitungsende 8 vollständig von dem Material der zweiten Komponente K2 umschlossen. Bei den Ausführungen gemäß 1 bis 5 wird das innere Ende der Aufnahmeöffnung 6 durch eine radiale Anlagestufe 14 gebildet, an der das eingesteckte Leitungsende 8 zur Anlage gelangt. Auf diese Weise geht der innere Medienkanal 12 unmittelbar in das Leitungsende 8 über, so dass auch in diesem Bereich der Medienkanal 12 vollständig einerseits vom Material der zweiten Komponente K2 und andererseits vom Material des Leitungsendes 8 umschlossen ist. Hierdurch eignet sich die Verbindungsvorrichtung 1 auch für Medien, die beispielsweise vor einer äußeren UV-Bestrahlung geschützt werden müssen. Dazu werden die zweite Komponente K2 und das Leitungsende 8 mit entsprechenden Materialanteilen ausgelegt, die eine UV-Beständigkeit gewährleisten. Dies wird insbesondere durch eine schwarze Färbung erreicht.In an advantageous embodiment is an inner media channel 12 of the connection part 2 over its entire course length away to an inner, plug-in end region of the receiving opening 6 for the cable end 8th completely enclosed by the material of the second component K2. In the embodiments according to 1 to 5 becomes the inner end of the receiving opening 6 through a radial investment stage 14 formed at the inserted end of the line 8th comes to the plant. This is how the inner media channel goes 12 directly into the cable end 8th over, so also in this area the media channel 12 completely on the one hand by the material of the second component K2 and on the other hand by the material of the cable end 8th is enclosed. As a result, the connecting device is suitable 1 also for media that need to be protected against external UV radiation, for example. For this purpose, the second component K2 and the cable end 8th designed with appropriate material components, which ensure UV resistance. This is achieved in particular by a black color.

Bevorzugt ist das Anschlussteil 2 mit seinen Komponenten K1, K2 als einstückiges Mehrkomponenten-Formteil (Spritzgussteil) ausgebildet. Dies bedeutet, dass die Komponenten K1, K2 materialeinheitlich, stoffschlüssig homogen miteinander verbunden sind. Alternativ dazu kann aber die erste Komponente K1 auch als ursprünglich separates, ring- oder hülsenförmiges Element ausgebildet sein, welches dann beim Schweißvorgang einerseits mit dem Leitungsende 8 und andererseits auch mit der zweiten Komponente K2 verschweißt wird. Hierbei überdeckt die erste Komponente K1 den Bereich des Stirnendes des eingesteckten Leitungsendes 8 axial in beiden Richtungen. Es ist auch eine Herstellung in der Weise möglich, dass eine der beiden Komponenten (insbesondere K1 oder aber K2) als separat vorgeformtes Teil in ein Spritzwerkzeug eingelegt und dann die andere Komponente (K2 oder K1) angespritzt wird.The connection part is preferred 2 formed with its components K1, K2 as a one-piece multi-component molded part (injection molded part). This means that the components K1, K2 are materially homogeneous, materially connected to each other homogeneously. Alternatively, however, the first component K1 may also be designed as originally separate, ring-shaped or sleeve-shaped element, which then, on the one hand, with the line end during the welding process 8th and on the other hand also welded to the second component K2. In this case, the first component K1 covers the region of the front end of the inserted line end 8th axially in both directions. It is also possible to manufacture in such a way that one of the two components (in particular K1 or K2) is inserted as a separately preformed part in an injection mold and then the other component (K2 or K1) is injection-molded.

Die Verschweißung erfolgt insbesondere radial im Umfangsbereich zwischen dem Leitungsende 8 und der Aufnahmeöffnung 6. Zusätzlich oder aber alternativ kann auch eine axiale Verschweißung im Bereich der Anlagenstufe 14 und des anliegenden Stirnendes des Leitungsendes 8 erfolgen. Gemäß 3 kann es dazu zweckmäßig sein, in diesem Bereich, d. h. axial zwischen dem Leitungsende 8 und der Anlagestufe 14, eine Kunststoffschicht 16 anzuordnen, die aus einem mittels Laserstrahl zu schmelzenden Werkstoff besteht. Gemäß 4 kann grundsätzlich auch radial zwischen der Aufnahmeöffnung 6 und dem Leitungsende 8 eine solche Kunststoffschicht 18 angeordnet sein. Die Ausführungen gemäß 3 und 4 können auch miteinander kombiniert werden, d. h. es können beide Schichten 16 und 18 gleichzeitig vorgesehen sein. Die Kunststoffschichten 16, 18 können als Folie, Hülse, Beschichtung, Bedruckung oder Bedampfung konzipiert sein.The welding takes place in particular radially in the peripheral region between the line end 8th and the receiving opening 6 , Additionally or alternatively, an axial welding in the area of the plant stage 14 and the adjacent front end of the line end 8th respectively. According to 3 it may be expedient in this area, ie axially between the line end 8th and the investment level 14 a plastic layer 16 to arrange, which consists of a material to be melted by laser beam. According to 4 can basically also radially between the receiving opening 6 and the cable end 8th such a plastic layer 18 be arranged. The statements according to 3 and 4 can also be combined with each other, ie it can be both layers 16 and 18 be provided simultaneously. The plastic layers 16 . 18 can be designed as foil, sleeve, coating, printing or vapor deposition be.

Bei der Ausführung gemäß 5 ist radial zwischen der ersten Komponente K1 und der Aufnahmeöffnung 6 noch ein beispielsweise hohlzylindrischer Abschnitt der zweiten Komponente K2 angeordnet. Dieser Abschnitt bildet eine Aufschmelzzone 20 zwecks Verschweißung mit dem Leitungsende 8.In the execution according to 5 is radially between the first component K1 and the receiving opening 6 another example, a hollow cylindrical portion of the second component K2 arranged. This section forms a melting zone 20 for welding with the cable end 8th ,

Für das Verschweißen im Laserstrahl-Schweißverfahren ist es vorteilhaft, wenn die erste Komponente K1 in einem zumindest die Aufnahmeöffnung 6 axial überdeckenden Bereich eine zylindrische Außenfläche 22 aufweist. Wie in 6 veranschaulicht ist, kann hierdurch ein Laserstrahl 24 senkrecht zur Längsachse 26 der Aufnahmeöffnung 6 bzw. des Anschlussabschnittes 4 und damit radial und auch senkrecht zur Außenfläche 22 ausgerichtet werden. Hierdurch wird eine geringstmögliche Reflexion erreicht, um einen möglichst großen Anteil des Laserstrahls zur Schweißzone 28 im radial zwischen der Aufnahmeöffnung 6 und dem Leitungsende 8 eindringen lassen zu können.For welding in the laser beam welding method, it is advantageous if the first component K1 in at least one receiving opening 6 axially overlapping area a cylindrical outer surface 22 having. As in 6 is illustrated, thereby a laser beam 24 perpendicular to the longitudinal axis 26 the receiving opening 6 or the connection section 4 and thus radially and also perpendicular to the outer surface 22 be aligned. As a result, the lowest possible reflection is achieved in order to maximize the proportion of the laser beam to the welding zone 28 in the radial between the receiving opening 6 and the cable end 8th to be able to penetrate.

Wie weiterhin in 6 dargestellt ist, kann es alternativ oder zusätzlich vorteilhaft sein, wenn die erste Komponente K1 eine Konusfläche 30 derart aufweist, dass ein schräg zur Längsachse 26 ausgerichteter und die Konusfläche 30 senkrecht treffender Laserstrahl 24 durch die erste Komponente K1 hindurch bis zu einer Schweißzone 32 eindringt, die axial zwischen der in diesem Fall von der ersten Komponente K1 gebildeten Anschlagstufe 14 und dem vorderen Stirnende des Leitungsendes 8 liegt. Hierdurch lässt sich das Leitungsende 8 auch axial verschweißen.As continues in 6 is illustrated, it may alternatively or additionally be advantageous if the first component K1 is a conical surface 30 such that an oblique to the longitudinal axis 26 aligned and the cone surface 30 vertical laser beam 24 through the first component K1 through to a welding zone 32 penetrates axially between the stop step formed in this case by the first component K1 14 and the front end of the pipe end 8th lies. This allows the end of the line 8th also welded axially.

Die Außenfläche 22 bzw. die Konusfläche 30 ist „relativ glatt" ausgebildet, d. h. mit einer maximalen Rauhigkeit, wie sie bei Spritzgussteilen üblich oder erreichbar ist.The outer surface 22 or the cone surface 30 is formed "relatively smooth", ie with a maximum roughness, as is common or achievable in injection molded parts.

Grundsätzlich kann unter bestimmten Bedingungen der Laserstrahl 24 auch schräg zur jeweiligen Oberfläche 22/30 ausgerichtet werden. Außerdem ist es möglich, die jeweilige Fläche so, insbesondere im Radial- und/oder Axialschnitt gesehen konvex gekrümmt, zu gestalten, dass eine Linsenwirkung zur Konzentration der Laserstrahlen erreicht wird.Basically, under certain conditions, the laser beam 24 also obliquely to the respective surface 22 / 30 be aligned. Moreover, it is possible to make the respective surface convexly curved, in particular in the radial and / or axial section, in such a way that a lens effect for concentrating the laser beams is achieved.

Gemäß 6 wird beim Schweißprozess jeweils der Laserstrahl 24 um die Längsachse 26 herum bewegt (vgl. den Pfeil 34), um das Leitungsende 8 über seinen gesamten Umfang dicht zu verschweißen.According to 6 In the welding process, the laser beam is used 24 around the longitudinal axis 26 moved around (see the arrow 34 ) to the cable end 8th to weld tightly over its entire circumference.

In diesem Zusammenhang ist es wichtig, die Aufnahmeöffnung 6 bezüglich ihres Innenquerschnittes in Anpassung an den Außenquerschnitt des Leitungsendes 8 derart auszulegen, dass das Leitungsende 8 radial spielfrei mit einer Übergangspassung oder einer Presspassung einsteckbar ist. Auf diese Weise kann – neben der mechanischen Festigkeit – eine bezüglich der Dichtheit hochwertige Schweißverbindung erreicht werden.In this context, it is important to the receiving opening 6 with respect to its inner cross section in adaptation to the outer cross section of the line end 8th interpreted in such a way that the line end 8th Radially free of play with a transition fit or a press fit can be inserted. In this way - in addition to the mechanical strength - a high-quality seal with respect to the tightness can be achieved.

Wie sich noch aus 7 ergibt, kann das Anschlussteil 2 im außerhalb des Anschlussabschnittes 4 liegenden Bereich der Komponente K2 eine beiliebige Oberfläche, beispielsweise auch Rippenansätze 36 zur Halterung von Heizdrähten 38 einer elektrischen Heizeinrichtung aufweisen. Diese Ausgestaltung ist insbesondere für eine Applikation vorteilhaft, bei der ein gefriergefährdetes Medium durch das Anschlussteil 2 bzw. dessen Medienkanal 12 geführt werden soll, wie es beispielsweise bei Wasserleitungen für Scheibenwaschanlagen in Kraftfahrzeugen sowie auch bei Leitungen für eine Harnstofflösung der Fall ist, die als NOx-Reduktionsadditiv für Dieselmotoren mit so genannten SCR-Katalysatoren eingesetzt wird.How to get out 7 results, the connection part 2 in the outside of the connection section 4 lying region of the component K2 an arbitrary surface, for example, rib approaches 36 for holding heating wires 38 having an electric heater. This embodiment is particularly advantageous for an application in which a medium which is susceptible to freezing through the connection part 2 or its media channel 12 is to be performed, as is the case for example with water pipes for windscreen washer systems in motor vehicles and also for lines for a urea solution, which is used as NO x reduction additive for diesel engines with so-called SCR catalysts.

In weiterer vorteilhafter Ausgestaltung der Erfindung sind die Komponenten K1 und K2 so konzipiert, dass sie sich von ihrem äußeren Aussehen voneinander unterscheiden. Dies kann beispielsweise durch ein unterschiedliches Reflexionsverhalten für das Spektrum des sichtbaren Lichtes erreicht werden, insbesondere durch unterschiedliche Farben. Durch die erste Komponente K1 wird somit die Schweißzone gekennzeichnet, in der der Laserstrahl zugeführt werden soll. Somit dient die Komponente K1 zusätzlich als Indikator für die Schweißzone. Außerdem kennzeichnet sie die Art des Anschlussteils 2 gegenüber andersartigen, z. B. angespritzten Anschlussteilen.In a further advantageous embodiment of the invention, the components K1 and K2 are designed so that they differ from each other in their external appearance. This can be achieved for example by a different reflection behavior for the spectrum of visible light, in particular by different colors. By the first component K1 thus the welding zone is marked, in which the laser beam is to be supplied. Thus, the component K1 additionally serves as an indicator of the weld zone. It also identifies the type of connector 2 opposite types, z. B. molded connection parts.

Die Erfindung führt zu dem wesentlichen Vorteil, dass der weitaus größte Teil des Anschlussteils 2, nämlich die zweite Komponente K2, in ihrer Materialzusammensetzung frei komponierbar ist und beliebige Verstärkungsstoffe und/oder Additive enthalten kann. So ist beispielsweise für eine hohe mechanische Festigkeit ein hoher Glasfaser-Anteil von Z. B. 30 bis 50% möglich. Dennoch lässt die lasertransparente Komponente K1 eine optimale Verschweißung im Laserstrahl-Schweißverfahren zu.The invention leads to the significant advantage that by far the largest part of the connection part 2 , namely, the second component K2, is freely composable in their material composition and may contain any reinforcing materials and / or additives. For example, a high glass fiber content of, for example, 30 to 50% is possible for high mechanical strength. Nevertheless, the laser-transparent component K1 allows optimum welding in the laser beam welding process.

Die Erfindung ist nicht auf die dargestellten und beschriebenen Ausführungsbeispiele beschränkt, sondern umfasst auch alle im Sinne der Erfindung gleichwirkenden Ausführungen. Ferner ist die Erfindung bislang auch noch nicht auf die im Anspruch 1 definierte Merkmalskombination beschränkt, sondern kann auch durch jede beliebige andere Kombination von bestimmten Merkmalen aller insgesamt offenbarten Einzelmerkmalen definiert sein. Dies bedeutet, dass grundsätzlich praktisch jedes Einzelmerkmal des Anspruchs 1 weggelassen bzw. durch mindestens ein an anderer Stelle der Anmeldung offenbartes Einzelmerkmal ersetzt werden kann. Insofern ist der Anspruch 1 lediglich als ein erster Formulierungsversuch für eine Erfindung zu verstehen.The invention is not limited to the illustrated and described embodiments, but also includes all the same in the context of the invention embodiments. Furthermore, the invention has hitherto not been limited to the feature combination defined in claim 1, but may also be defined by any other combination of specific features of all individually disclosed individual features. This means that in principle virtually every single feature of claim 1 omitted or by at least one elsewhere in the message disclosed individual feature can be replaced. In this respect, the claim 1 is to be understood only as a first formulation attempt for an invention.
