Title: electrolytic tumbling drum - has anode system in conformity with the charge displaced by rotation
Inventor: HENIG HANS
IPC: C25D17/20
Filed: 1989-06-26
Abstract: A tumbling drum for the electrolytic surface treatment of free running bulk material in aqueous solutions has a prismatic shape with perforated walls. Its anode system is arranged to be equidistant to the envelope around the charge which acquires a sideways shift. The tumbling drum (1) dips with its perforated hexagonal shell completely in the electrolyte of the vat (5). During rotation, the charge (2) forms a slope (A-D) with an envelope (ABCDA).  The boxes of the anode system (31,32,33,34,35) are arranged in conformity with this envelope and are of e.g. titanium filled with soluble anode cubes. The boxes (33,34) are hinged to facilitate lowering and lifting of the drum. ADVANTAGE - This results in a considerable rise in both the quality and the quantity of the reduced surface layers (in the case of electrolytic polishing).

Title: Projectile with explosive charge - has charge retained by end cover and ring secured with Adhesive
Inventor: FRYE GUENTER
IPC: F42B1/02
Filed: 1990-01-16
Abstract: The projectile (18) has a housing (16) with an explosive charge (14) which is detonated in order to fire the projectile from a gun. The explosive charge (14) is held in place by an end cover (12) . This end cover is secured by a ring (10) with a flange (24) which projects radially inwards. This ring (10) is attached to the housing by means of adhesive placed between the abutting surfaces. The adhesive enables the ring to be detached from the housing (16) so that the projectile can be driven out of the gun barrel by the pressure generated by the explosive charge. Instead of using adhesive, lines of weakness may be formed in the ring so that it breaks and allows the projectile to be fired. USE - Projectiles for guns.
