Title: Magnetic wire store unsusceptible to defects - has orthogonally aligned word tracks and wires consisting of bit tracks
Inventor: WALTER KARL-HEINZ DIPL ING
IPC: G11C7/00
Filed: 1973-09-19
Abstract: The electrically conductive wires are coated with a magnetic layer, which has a preferred direction of the magnetization. The information to be entered is compared with the stored information and is entered only if the information differs. Provided, that the currents fed into the bit tracks are below the value IHc, basically the bipolar writing can be replaced by unipolar writing. This means a further saving of 50% of the current fed into the bit tracks and to a certain extend contributes to an increase in speed. A reduced consumption of current is achieved, which enhances the considerable advantages for application in space travel.

Title: Foundation piles production using localised concrete placement - involves driving thrust pipe with lost head into ground and filling it with concrete
Inventor: REICHERT ERNST DIPL ING
IPC: E02D5/42
Filed: 1975-01-15
Abstract: The thrust pipe (1) which has an external diameter of between 12 and 30cm is driven into the ground by a ram applied from above. In so doing the adjoining soil is compressed. Once at the required depth, the pipe is filled over its entire length through a feed line with pumpable, hardenable constructional material e.g. concrete (4). Suitable reinforcement (5) can be placed in the pipe before pouring the concrete so that the finished foundation piling is strengthened. Subsequently the thrust pipe is withdrawn while pressure is still applied down it. In this way the concrete below the lost head (3) of the pipe is forced into the hollows in the surrounding soil. The result is stronger defect-free piling.
