Title: Automatic fillet-weld tracking mechanism
Inventor: MURAKAMI MASAHIRO
IPC: B23K9/127
Filed: 1981-07-09
Abstract: An automatic fillet-weld tracking mechanism for two components to be welded is described, these components being arranged stepwise and parallel to one another and concentric to one another or with another similarity relationship. A first motor drive mechanism is arranged at a fixed level and serves to move a first drive member vertically in a reciprocating manner. A first sensor is fastened to the first drive member. The first sensor is positioned in proximity to the first component, which is to be welded with a certain gap to the second component. Another drive mechanism is firmly connected to the first drive member and is used for the perpendicular reciprocating movement of a second drive member, which is in turn connected to a second sensor. The second sensor is held in proximity to the second component. The second drive mechanism drives a third drive member via a differential gear with a predetermined gear ratio. The third drive mechanism leads to a perpendicular reciprocating movement of the third drive member. The welding torch or the welding electrode is connected to the third drive member. The welding torch is arranged in such a way that the gap between the components is welded. The control devices are designed in such a way that they activate the first and second drive mechanism, specifically in response to a change in the gap width, which is detected by the two sensors. In this way, the welding torch is always held in a predetermined position relative to the fillet-weld gap irrespective of the changes in the position of this gap.

Title: Process for stabilising high-purity zinc for primary galvanic cells
Inventor: GUGENBERGER THOROLF DR
IPC: H01M4/06
Filed: 1981-11-20
Abstract: High-purity mercury-free anode zinc in powdered or paste form only exhibits a low tendency to hydrogen gassing if it is exposed for several days to the action of hot alkali metal hydroxide solution at approximately 60 DEG C. Even zinc doped with silver to inhibit corrosion can be "thermostabilised" in this way. The hydroxide solution treatment time is determined by a gassing maximum which occurs in the variation of the action as a function of time and which has to be exceeded. Thereafter a persistant pseudopassivity sets in.

Patent DE-3206642-A1 (DE)
Title: Muzzle attachment for high-powered barrel weapons
Inventor: WEISE CHRISTIAN
IPC: F41A21/46
Filed: 1982-02-24
Abstract: The use of propellent-charge projectiles entails disadvantages (reduction of the firing accuracy, endangering the area in front) which are to be decreased by means of the invention. For this, the muzzle of a smooth or rifled high-powered barrel weapon is preceded by a muzzle attachment which is designed as a decelerator for the purpose of substantial braking, at the same time with a reshaping of a propellent charge consisting of a light, tough and high-strength material. The said disadvantages are appreciably decreased, and to be seen as advantages are, in particular, the improvement in firing accuracy as the result of the prevention of separation faults between the projectile and propellent charge, the elimination of the endangering of the area in front, brought about by the very short flight path of the braked propellent charge, and the great reduction in the weapon recoil as a result of the impact of the propellent charge on the decelerator. The muzzle attachment can be used likewise for fin-stabilized or spin-stabilized propellent-charge projectiles, and combination with muzzle brakes and the like can be carried out without difficulty.
