Title: Reducing acidic water formation esp. in coal tip - by locating iron di:sulphide-rich spoil below other waste
IPC: E21C41/32
Filed: 1991-03-04
Abstract: Acidic sulphate-contg. water formation in tips, esp. of brown coal mines is reduced by separating the low disulphide content layers from the disulphide-rich layers during spoil extraction and positioning the disulphide-rich material below the low disulphide content material in the spoil tip.

Title: Control or regulation of electric motor using pulse modulation - supplying control signal of control stage to motor control circuit which essentially only amplifies this and, by amplified signal, supplies current to motor
Inventor: LINK HERMANN
IPC: G11B15/46
Filed: 1992-06-17
Abstract: The control signal(s), depending on the type of the control stage used, is supplied directly to a motor control stage, or it is next prepared by a pulse modulation stage.
