Title: Automatic vehicle guidance system - uses horizontal and vertical coils on-board vehicle to monitor magnetic field from conductor wires along vehicle path
Inventor: AUKSUTAT GUENTER DIPL ING
IPC: G05D1/02
Filed: 1979-07-19
Abstract: The system uses conductor wires extending along the required vehicle path. These wires are coupled to an AC source, with their magnetic field monitored by inductive coupling coils on board the vehicle positioned horizontally and vertically. The voltage induced in the vertical coil is rectified and supplied to a current multiplier, where it is multiplied by a value proportional to the rectified current in the conductor wire. The squares of the induced voltages for both coils are added, after multiplying the square of the induced voltage for the horizontal coil by a constant. The output of the initial current multiplier is then divided by the output of the adder, to provide a regulation valve for steering the vehicle along the required path.

Title: Submerged arc welding in inert gas - so weld deposits with high notch impact toughness can be obtd.
Inventor: STRZELETZ GUENTER DIPL ING
IPC: B23K9/18
Filed: 1979-12-05
Abstract: During submerged arc welding, the powder is covered by a hood filled with inert gas; and the height of the welding powder is 4-5 times the electrode dia. Immediately after the weld deposit has solidified, the slag is removed while it is still molten. The molten slag is pref. removed by brushing. With conventional submerged arc welding, the notch impact toughness (NIT) of the weld deposit is lower than the NIT of the workpieces, one of the causes being the poor temp. control resulting from a powder height of 8-10 times the electrode dia. The invention uses a lower powder height and inert gas so the cooling rate of the weld is increased but not pores are formed in the deposit. Rapid slag removal also increases the cooling rate and further improves the NIT of the deposit.

Title: Differential AC transistor amplifier - has limited minimum gain independent of control voltage
Inventor: WAGNER SIEGFRIED
IPC: H03G3/30
Filed: 1980-03-15
Abstract: The amplifier comprises two transistors (T1,T2) which receive the input signal (Ue) in parallel and in phase. One path (T2) is connected to the control voltage (UR), the other to a fixed threshold voltage (U1). The two transistor paths have dissimilar loading resistors (R1,R2). For a desired amplification ratio of Delta V = Vmax-Vmin. the loading resistors are chosen with the same ratio. The loading resistors may be either directly connected to the transistor circuit, or transformer coupled with different ratios to a single load. If the threshold voltage is higher than the control voltage the first path (T1) conducts, the larger load (R1+2) is in circuit, and the gain is maximum. The other transistor is blocked. As the voltages approach equality both circuits conduct and the gain falls off. When the control voltage is significantly the higher only the second transistor (T2) conducts. The lower resistor (R2) is in circuit and the gain is minimum.
