Title: Starting circuit for push-pull chopper with unijunction transistor - applies RC circuit start signal to single auxiliary winding on chopper transformer
Inventor: KREUTZ WALTER DIPL-ING
IPC: H02M7/5375
Filed: 1969-09-27
Abstract: The starting circuit, for a push-pull chopper, starts the chopper oscillating even with slowly rising voltages and therefore requires no second auxiliary winding. The chopper contains a transformer with a feedback winding and a single auxiliary winding that applies the starting signal to the chopper transistors. The d.c. supply is voltage stabilised and applied via an RC circuit to a unijunction transistor. The transistor produces the starting signal which is amplified and applied to the auxiliary winding. After the chopper has begun to oscillate, a rectangular waveform is induced in the auxiliary winding. This waveform is rectified and applied to a transistor which short circuits the RC circuit's capacitor -- the starting signal then stops.

Title: Traction system for rails vehicles - has wheels which are alternately brought into contact with the track
Inventor: HELM AXEL-GUENTHER DR RER NAT
IPC: B61B13/12
Filed: 1974-03-04
Abstract: The system for supporting a moving body by wheels in alternating contact with the track is used to reduce the friction and heat in the track and for application in the transport system. The wheels are driven by the contact with the rail. When the contact with the rails is interrupted then the bearing friction causes a reduction of the rotating speed during the cooling or rest phase. The constant speed on reconnecting the wheel with the rails can be ensured by using inertia masses during the engagement as centrifugal masses while the cooling or rest phase is produced by a centripetal effect. These wheels can also be replaced by sliding elements. The alternating contacting of the rotating wheels with the track can be produced by means of pneumatic, hydraulic, mechanical, electrical or electronic systems incorporating driving and actuating elements.
