Title: Lateral compaction of soil layers - by pressing wedge-shaped form into soil layers at set intervals by roller or compaction plate to raise soils lateral stiffness
Inventor: SCHMIDT GERHARD
IPC: E02D3/026
Filed: 1991-05-11
Abstract: In addition to compacting the soil vertically, a lateral stiffening of the soil can be achieved by the introduction of shaped sections (1) into the soil layers. These sections are compressed into the soil by a roller (2) or a compaction plate. The triangular sections are placed resting on one face on the surface of the soil. When the roller presses the sections down, it rotates them so that they lie buried with one side flush with the soil surface and a vertex pointed downwards. A further layer of soil is spread on top, more shaped sections are laid down and the process is completed. USE/ADVANTAGE - Vertical compaction of soil with additions of shaped metal sections for lateral reinforcement.

Patent DE-4124240-A1 (DE)
Inventor: ALBRECHT KAI
IPC: H02P6/06
Filed: 1991-07-22
Abstract: The object of the invention is to propose a method for the regulation of a brushless DC motor, in which the current ripple of the motor is minimised. To this end, on reaching the desired value of the motor current (IM), a switchable semiconductor valve (Tr1, ..., Tr4) in the bridge arm which is being acted on is switched off for a time period (ts) governed by the speed of the motor. In consequence, the clocking frequency of the switchable semiconductor valves is also minimised, which contributes to a considerable reduction in motor noise as well as increasing the life of the transistors. <IMAGE>
