    Abstract: The present invention concerns a reinforced conductive layer (7). The layer is applied at a part (3a,b) of an electrical unit, e.g. a mobile telephone, which is to come into contact with another part (3a,b). The layer (7) will protect the covered material against corrosion due to formation of a galvanic element. In a preferred embodiment of the invention the layer (7) is made of the made material as the part (3a,b) which it will come into contact with. Furthermore, spaces (16) may be formed in assembly of a mobile telephone, which spaces (16) are surrounded by conductive material. (FIG. 1)

    Abstract: The present invention relates to a method and an arrangement for transferring a conductive picture (12) to an irregular surface of a mobile phone casing (4) for shielding the mobile phone casing from electromagnetic radiation. It also relates to the printing colour used for the conductive picture and tampon pads (5) used for the transferring of the conductive printing colour to the phone casing (4). Conductive partial pictures (7) are printed on the irregular surface of the casing (4) step by step by means of tampon pads until the complete conductive picture (12) is achieved. The tampon pad has a shape corresponding to the surface of the phone casing. The printing colour has a composition, which facilitates the adhering on the tampon pad. The invention also describes a method for printing an electrical circuit pattern on a phone casing (4) by using the above mentioned tampon pads and printing colour.

    Abstract: In a method of interconnecting two elements (10, 11) of plastic material by welding or gluing together surfaces of the elements a channel (12) is formed in one of said elements, which is divided by partitions (16) into individual spaces distributed longitudinally of the channel. The partitions and the side walls (14, 15) of the channel along the edge surfaces (17, 18, 19, 20) thereof are connected with the other element (11) by welding or gluing together said edge surfaces.

    Abstract: Tamp printing of at least one picture ( 4 ) occurs by means of at least one tamp pad ( 1, 18, 24, 34 ) on a piece ( 3 ), which has boundary surfaces ( 5, 13 ) forming angles relative to each other, the tamp pad first printing in one direction ( 10 ) against a boundary surface ( 13, 43 ) and thereafter, after further compression of the tamp pad ( 1 ) against said boundary surface ( 13 ) due to its deformation, prints in another direction ( 45 ) than the direction ( 10 ) against another boundary surface or other boundary surfaces ( 5, 43 ), whereby the picture is transferred to said boundary surfaces.
