Title: Speed controlled synchronous machine - uses thyristor converter and can regulate ccts. for constant flux and voltage
Inventor: GOELZ GUENTHER DIPL-ING
IPC: H02P25/03
Filed: 1973-08-30
Abstract: The control system ensures optimum operating conditions in either motoring or generating mode over the required speed range. At sub-synchronous speeds, referred to the primary supply frequency, the machine flux is held constant by regulation of the voltage applied to the armature, whilst at super-synchronous speed the voltage is held constant at a value determined by the thyristor blocking capability. When motoring the off time of the machine side inverter is controlled by an off time regulator. When generating the intermediate d.c. circuit voltage is controlled by another regulator. Depending on operation mode the output of one or other regulator is fed to a controller along with signals from the rotor position indicator to adjust the rotor angle of the machine by controlling the firing of the machine side thyristor bridge.

Title: Automatic weighing and separating device for tobacco - avoids vibrations by separation of weighing container from support
Inventor: FOCKE HEINZ
IPC: G01G13/16
Filed: 1974-07-27
Abstract: The separation of the weighing from its support is carried out during work cycle periods outside actual measurements. In order to carry out the actual separation the load is exchanged between the support and puttisng-down frame. This is realised by moving the support vertically down towards a stop, so that current from the test coil is disconnected and the weighing arm can be lowered. The weighing funnel comes to rest on the frame; or the frame (14) is lifted and uncoupled, so that the support rests on it. This alternative coupling between the support weighing funnel and frame is achieved by deflectors and centring cones.
