Abstract: A locking seal for sealing objects comprises a seal element (1) and a fixing pin (3) having a punctiform end part (4) and a counterelement (8). The seal element (1) comprises a main plate (9) and a closing plate (10), the rims (14,15,16,17) of said plates being connected with one another. The main plate is, at least in a fastening part; completely closed and together with the closing plate it bounds a space (13), in which a clamping means is located. When the locking seal is closed, the fixing pin is passed by the end part (4) through an orifice in the closing plate and clamped tight by the clamping means with respect to the seal element.

Abstract: A tattooing device comprises a needle carrier (1) having a plurality of hollow needles (2), an exchangeable program carrier (11,26,31,39) and control means having a jaw (7). The program carrier has an assembly of cylindrical cavities (13,28,33,40) with a fluid (23), each of which can be put into open communication with a needle, in which cavities pistons (6,18,34,38) are movable for pressing out the fluid and which cavities are at least partly closed at an axial end by a closing element (18,29,34,41) in dependence on the force exerted by the jaw for transfer to the needle. The closing element is at least partly deformable, the deformation of the closing element requiring a heavier force than that required for inserting the needle into the tissue so that owing to the force exerted by the jaw on the program carrier first the needle is inserted into the tissue and subsequently by the deformation of the closing element the piston can move into the cavity.

Abstract: A tatooing apparatus is provided with at least one needle carrier (17, 42, 47) with an arrangement of needles (19, 44, 46) by which at least a number of the needles are mutually arranged according to a program of symbols and in such a manner that the tissue to be tattooed can be pierced by the free ends of the needles. Each of the needles is hollow and is provided with an outlet opening close to its free end for feeding a contrasting fluid into the perforation in the tissue. The apparatus is further provided with a fluid feeding mechanism a control mechanism therefore, the fluid feeding mechanism comprising a reservoir (16, 43, 54) accommodating contrasting fluid and a program carrier of non-porous material, the program carrier also including perforations (30, 49) which are directed in relation to the inlet openings of the needles.
