Abstract: Hypodermic needle 2 is to be introduced between the skin and the tissue adjacent to the skin. To separate the skin from the tissue, cartilage or bone below the skin and to prevent the tip 6 of the needle 2 from piercing the tissue below the skin this invention discloses providing the extremity 6 of the needle with a protrusion 4. To prevent damage to the living being in which the needle 2 is introduced the transition of the protrusion 4 to the needle is smooth in all directions. The protrusion 4 is provided on that side of the needle which will be adjacent to the tissue, cartilage or bone of the living being.

Abstract: Apparatus for introducing a transponder in a living being wherein the transponder itself is outfitted with a sharpened member attached to the injection end of a transponder. The sharpened member comes in contact with the skin before the transponder thereby creating an opening in the skin such that the transponder can be blunt edged and move into the opening easily. The sharpened member is preferably constructed of a bio-compatible, preferably biodegradable material which may carry medication additionally.

Abstract: Injector (1), comprising a housing to which is fixed a hollow needle (17) provided with conveyance means (3,4) for moving an object such as a transponder (22) through said needle (17). Such transponders (22) are inserted in living beings for identification purposes. Metering means (11,12) are provided in the injector (1)in order to permit the introduction of a fluid such as a disinfectant during the insertion of such objects (22). Such means comprise a storage place for fluid (11) which is connected to channel means (8) which open into the movement path of the object (22). In this way fluid is added during the positioning of the object (22).

Abstract: Injector for hypodermically implanting of an object (14) in a living being. This injector comprises a housing (13), with a hollow needle (3) which can be moved in and out from the housing (13). In the hollow needle (3) a pushing rod (9) is received, to position an object (14) in a living being after introduction of the needle (3). Near the housing (13) a locking means is provided to realize positioning of the object. In the storage position, the needle (3) is inside the housing (13). For injecting, first of all the needle (3) is moved out of the housing (13) and locked. A spring (4) is tensioned by the outward movement of the needle (3). During introduction into the animal of the needle (3), a locking means will be actuated, after which the needle (3) returns and positioning of the object (14) is realized.

Abstract: The line-wise printing of an image composed of an assembly of image elements (pixels) by means of a printing head which includes a row of N (N.gtoreq.2) printing elements which are arranged along an image line at a mutual distance from each other. The printing stroke is greater than the distance between two neighboring printing elements so that there is created at least one strip in the image in which there are pixel positions which are covered by m (2.ltoreq.m.ltoreq.N) printing heads. For this strip (or strips) several options are then presented for printing the pixels situated within them. A pixel in such a strip can now be printed by one or by several of the m printing elements, the allocation of one or more of these m printing elements to a position being capable of being chosen as fixed or variable.
