Patent DE-3108974-A1 (DE)
Title: Electric test instrument
Inventor: SCHAUERTE HUBERTUS
IPC: G01R31/50
Filed: 1981-03-10
Abstract: The electric test instrument has a test probe, a light-emitting diode display and a key (A) for checking phase, neutral conductor, earth conductor and induction voltage, and a key (B) for continuity testing and for testing electric components. During mains voltage testing, the test probe is brought into contact with the phase, neutral or earth conductor respectively. In this process, the presence or absence of the phase, neutral or earth conductor are distinguished by the different indication of the light-emitting diode by not touching or touching the key (A). In the case of an induction voltage, which is radiated by a mains cable through which current flows, the light-emitting diode display shows the presence or, in the case of an interruption, the absence, when the test probe is moved along the mains cable. Table II shows how the continuity is tested in the case of resistance and the time constant (T) is tested in the case of capacitance. By reversing polarity, the forward and reverse direction are found in the case of the diode and the transistor, and the polarity in the case of the battery. One terminal of the electrical component is picked up by hand, the test probe being applied to the second terminal, simultaneously touching the key (B) with the other hand. <IMAGE>

Patent DE-3117204-A1 (DE)
Title: Short circuit indicator with automatic resetting
Inventor: BLOSS GUENTER
IPC: G01R19/165
Filed: 1981-04-30
Abstract: The short circuit indicator is used in electrical systems or networks. It is intended to enable error sources with respect to short circuits to be rapidly found. Previous short circuit indicators which operate on a mechanical basis must be reset "manually". The advantage and the novelty of this short circuit indicator lies in the fact that it operates on a mechanical basis and automatically resets to its standby position when the network or the system is taken back into operation after it has operated. The entire unit does not need any external power. Its operation is given by the fact that a magnetically conductive armature, which can be rotated about an axis is located between a U-shape magnetically conductive bow and is parallel to the sides of the bow. As a consequence of a short circuit and the resultant magnetic field, the armature rotates across the sides of the bow. This position can be seen through a window in the housing of the short circuit indicator (indicating position). The armature is held in the indicator position by a lock. The lock is unlocked by an electronic circuit and a coil with an iron core. The coil obtains the power from a capacitor which is charged up via two potential plates as soon as there is voltage in the network. <IMAGE>

Patent DE-3201734-A1 (DE)
Title: Shaped-charge projectile
Inventor: MENIN DIDIER
IPC: F42B12/18
Filed: 1982-01-21
Abstract: Shaped-charge projectile with explosive head with a rear shaped charge and at least one front additional annular shockwave generator with an inner profile jacket, characterised by a pyrotechnic relay or delay section which consists of fuse cords, particularly detonating cords between the rear charge, on the one hand, and the additional front shockwave generator or generators, on the other hand. The additional shockwave generators generate a gas jet, the effect of which is additively superimposed on the effect of the gas jet of the rear charge of the projectile. The pyrotechnic relay or delay section ignites a step fuse of initial explosive and is capable of multiplying the number of ignition points at the head ring of the fuse cords. The fuse cords, in turn, are ignited by the rear main charge of the projectile and ignite the charges of the additional generator or generators at the opposite end, which achieves a stabilisation, homogenisation and equalisation of the resultant overall wave shape.
