Title: Multistage half controlled rectifier bridge - uses stages in cascade feeding common load to reduce reactive power demand
Inventor: LEHMANN GUENTER DIPL-ING DR
IPC: H02M7/162
Filed: 1973-09-01
Abstract: The object is to keep down the reactive power demand on the supply system whilst employing only a small number of rectifying devices. The system has particular application to traction motor control. The rectifier stages are connected to the secondary windings of the rectifier transformer. In a three stage example the secondary winding of the transformer is split into a 1/3 section and a 2/3 section which are connected to half controlled rectifiers with a commutating reactance in the common return. Initially the lowest voltage section is brought from zero to full, i.e. 1/3, output, whereupon the second section is brought in to take the output up to 2/3 with the first section blocked. Finally the first section is brought in again to raise the output to 100%.

Title: Vacuum impregnation process for electric machine windings - introduces carbon dioxide into windings before final evacuation and addition of resin
Inventor: KREMSER GUENTER
IPC: H02K15/12
Filed: 1973-11-26
Abstract: The vacuum impregnation process for a electric machine windings consists of first evacuating the housing containing the winding(s) and of filling it with a gas, such as carbon dioxide, that is absorbed by the resin. The housing is then again evacuated and the resin filled in over the winding(s). The pressure is chosen high enough to prevent the resin from boiling. The application of the carbon dioxide prevents air bubbles being trapped in the winding(s) and thereby reducing the effectiveness of the insulation. The process also allows a higher vacuum to be used so that there is no danger of the resin boiling.
