Patent DE-2811160-A1 (DE)
Title: Magnetically supported linear induction vehicle - has self aligning magnets with curved pole faces for lateral stability
Inventor: SCHWAERZLER PETER DIPL ING
IPC: B60L13/04
Filed: 1978-03-15
Abstract: The magnetically supported linear induction vehicle has two rows of servo magnets under the vehicle to interact with equally spaced rows of fixed magnets on the track. The pole faces of the two sets of magnets are curved (9, 10, 11, 12) so that lateral stability is assured when the vehicle is displaced laterally. The magnetic fields between the pole pieces when the system is laterally displaced is smoothly changing so that the return forces are no abrupt. The return forces also ensure that one magnet row is not overloaded unduly, leading to thermal problems.

Title: A=D conversion system using comparator - has reference values logarithmically spaced while converter performs linear function
Inventor: WESS GUENTER DIPL ING
IPC: H03M1/00
Filed: 1978-06-14
Abstract: The voltage to be converted and a reference voltage are applied to the converter inputs, and a digital-analogue conversion is also carried out which generates the reference voltages from the reference values. Depending on the polarity of the difference voltage at the comparator output, a new reference value is applied. The reference values (Vv1-VvN) are logarithmically spaced. The digital-analogue converter (DA) works linearly and the conversion is carried out in consecutive steps, so that the comparator (KO) output signal polarity delivers the logarithmic value of the input voltage (Ue) starting from the first comparison result as the leading bit of a binary signal.

Title: Twin-shaft plastics extruder - in which material is prevented from access to vents by large dia. rings on shaft adjacent to vents
Inventor: BLACH JOSEF A
IPC: B29C48/76
Filed: 1978-06-24
Abstract: Extruder has two meshing shafts driven in the same direction and each has several discs non-concentric with its shaft. Concentric rings lie between 1st and 2nd, 3rd and 4th etc. discs on one shaft and between the 2nd and 3rd, 4thand 5th etc. on the other.
