Abstract: Described is a method for applying optically readable code markings (14) on the surface of bottles (10) made of plastic or glass by producing depressions in the surface by means of a laser (12) in such a way that the base of each code marking (14) is formed as a diffusing reflector. For automatically reading the code markings, a sensor (16) constructed from optical fibres having centrally arranged emission optical fibres and radially arranged receiving optical fibres is used. The sensor forms an angle of less than 90 DEG with the bottle surface, so that light is reflected into the sensor only at points on the surface where code markings (14) are present. The code markings (14) are simple to apply and can be reliably read.

Abstract: A resistance seam welding machine is described, particularly for the longitudinal seam welding of can bodies, wherein, in the secondary loop (16), feed and return lines are constructed partially as a double line (18, 28) and in all the remaining portion (18a, 18b, 18c, 20, 24, 26) in the form of a substantially coaxial line. The voltage loss occurring in the secondary loop (16) between welding transformer (14) and welding position (8, 10) and the heat due to energy losses in the machine parts adjacent to the secondary loop are considerably reduced as a result of this construction of the feed return lines.
