Abstract: In the described device a wire (18), which is fed in by a wire guide (20), is wound on a shaping body (10) provided with recesses (16), of a rotatably driveable template (10, 12) and, in the course of the rotation of the latter, is cyclically pushed into the recesses (16) by radially movable outer shaping elements (12). Subsequently the wave-shaped wire windings are transferred into longitudinal slits of a coil receiver (34), which is positioned axially in front of the shaping body (10) and is essentially maintained fixed against relative rotation during the winding movement. In order to obtain complete wave windings over the circumference in a simple manner, it is provided that the shaping of the end of the last winding of a wave winding is finished in the allocated recess (16) by means of an additional inward movement of at least one of the shaping elements (12) in a different angle of rotation position of the template (10, 12) than during the cyclically performed shaping movement.

Abstract: A process to obtain linear double-stranded covalently closed DNA “dumbbell” constructs from plasmids by restriction digest, subsequent ligation with hairpin oligodesoxyribonucleotides, optionally in the presence of restriction enzyme, and a final digestion with endo- and exonucleolytic enzymes that degrade all contaminating polymeric DNA molecules but the desired construct. The invention also provides a process to obtain said dumbbell constructs employing endonuclease class II enzymes. Furthermore, the invention provides a process to obtain linear, covalently closed DNA molecules, such as plasmids, free from contamination by genomic DNA, by submitting the DNA preparation to a facultative endonucleolytic degradation step and an obligatory exonucleolytic degradation step.

Abstract: A section fixable in a mounted position to an anchoring base by means of fastening screws has at least one fastening segment extending in the mounted position substantially parallel to the anchoring base. The fastening segment is, for example, a fastening flange, which is provided with at least one screw hole for receiving a fastening screw provided with a slot or cross slot as the surface engaged by a screwdriver. A safety (or securing) tab protrudes from the fastening segment at least within the area of the screw hole. When the section is in its mounted position and after the fastening screw has been driven in, the safety tab can be deformed by bending or folding it into its safety or securing position. In this position, the tab grips over the edge of the screw head of the fastening screw and leaves free the surface engaged by the screwdriver. In an alternative embodiment of the section, a spring-elastic safety arrest is used instead of a bendable safety tab.

Abstract: A punching, stamping rivet has a frustrum-shaped rivet head and a shank with a shank groove following thereafter. In order to create a riveted joint between two sheets, the sheets are punched through by the shank. A groove is subsequently stamped around the shank end in the lower sheet, thus pressing material of the lower sheet into the groove. In order to increase the strength of the riveted joint, the shank groove is concavely constructed, whereby the section of the groove, which section is adjacent the rivet head, extends at an angle with respect to the shank axis, which angle is less than an angle at which the section adjacent the shank end extends with respect to the shank axis.
