Title: Anchoring for preventing buoyancy lift of structures - uses temporary tensioning members operated above ground water level
Inventor: ESTERS KLAUS DIPL-ING
IPC: E02D31/12
Filed: 1973-10-30
Abstract: The anchoring system is used for anchoring and securing of buildings against buoyancy forces due to the ground water level. It is used especially for building components sunk deep into the ground. The baseplate is held by injection anchors. The anchoring system opposes the buoyancy force exerted by the ground water level. The injection anchors pass through the baseplate into the ground and the anchor bars are held by the injection anchor in the ground below. The upper ends of the anchoring rods are held in tubes and they are tensioned at the top of these tubes by clamping arrangements. Subsequently the hardenable anchoring compound is pressed to anchor the rods and the hardenable material reaches the ground and hardens it. The water is pumped out of the concrete structure and the support pipes together with clamping heads are removed and the anchor bars are cut to the level of the floor of the baseplate. This arrangement does not require heavy baseplates for maintaining stability. No divers are used in fixing the injection anchors.

Title: Laser trimming for helical resistance layers - continuously measures resistance during cutting under control of binary counters
Inventor: ENGL ALFRED DIPL CHEM DR
IPC: H01C17/242
Filed: 1974-05-31
Abstract: The laser trimming process for cutting a helix into resistance layers continuously measures the layer or helix resistance by means of a bridge and turns off the cutting laser when a given resistance is reached. At the same time as the laser is switched on, a first binary counter starts counting forwards and a second counter starts counting backwards, the two counters being controlled by a frequency generator. When half the required resistance value is reached, the first counter is stopped, whilst the second one is allowed to continue. The laser is now switched off, but the drive system keeps going. As soon as the second counter contents equal the first one, the laser is switched on again until the full value of the required resistance is reached.
