Abstract: One aspect relates to a method of producing a sleeve for a ring electrode for electrophysiological and neuro-medical applications from a biocompatible metallic tape. Repetitive structures are punched into the tape and each includes at least one surface that is connected by at least one fin to at least one external strip. The at least one external strip connects the repetitive structures to each other on the margin. A sleeve mold is formed from a multiple of the repetitive structures through multiple reforming steps by a reforming technique. The sleeve mold is punched off the such that the sleeve is formed with a first tube-shaped region with a larger diameter and a second tube-shaped region with a smaller diameter. The first region with the larger diameter has a larger external diameter and internal diameter than the second region with the smaller diameter, and the two regions are connected.

Abstract: Disclosed is a bullet and practice cartridge for use on a shooting range having a cylindrical rear part and an ogive region at the nose end. The ogive region has a rear end and a bullet tip. In order that the bullet behaves like a conventional full metal jacket round nose bullet in a soft target, and moreover has a low energy output in the soft target, that the bullet does not deform or splinter in soft materials, and that the bullet does not puncture protective materials of bullet catchers, the bullet is constructed in one piece, the ogive region is closed all round a cavity and the wall thickness of the ogive region decreases constantly from the rear end to the tip.

Abstract: A forming machine (10) is provided for forming a finished part (12) from a flat blank (14). Draw stations (18-24) are provided to initially form the intermediate part. Each draw station includes a punch (44, 62, 66, 70') and a draw die (48, 64, 68, 72). Each punch defines a shoulder along its length to create a first step (60) in the side walls (26) of the intermediate part. In a subsequent draw stage, a draw punch (70') forms a second shoulder along its length to create a second step (100) in the side walls (26) of the intermediate part. A draw shoulder (61) on the draw punch (71') mates with the step (60) to maintain the concentric shape thereof. In the subsequent necking and final form stages (30, 32, 34) the punch employed also has a shoulder to permit variation of the force applied to the intermediate part between the step and bottom portion.
