Title: Electronic system of speed regulation of diesel engine - provides accurate control under no-load conditions
IPC: F02D41/38
Filed: 1974-02-22
Abstract: The control system consists of the Diesel engine with its injection pump, an electronic amplifier, a servo motor and two electronic differentiators. The amplifier is fed with signals concerning the actual speed of the engine, the required speed and the speed gradient. The amplifier controls the motor which adjusts the quantity of fuel delivered by the engine injection pump. By sensing the difference between actual and required speed and also sensing the speed gradient or engine acceleration, the system prevents over-speeding of the engine under the no-load conditions which occur when changing gear with an automatic or semi-autmatic gear box.

Title: Binary control data transmission circuit - transmission between F.M VHF broadcast senders with stereo transmission
Inventor: BUDNIK NORBERT ING GRAD
IPC: H04H20/34
Filed: 1974-05-17
Abstract: A V.H.F. stereo transmission system employs main senders and filling senders operated through relay receivers. Data is transmitted by frequency keyed carrier signals inserted into the transmission frequency band. The carrier signal frequencies are near the stereo pilots, and are derived from a fixed frequency generator by a frequency divider whose division ratio can be changed by the binary control data. They are at the receiving end filtered out by n-path filters controlled by a generator of the same fundamental frequency through two frequency dividers with the same division ratio, and demodulated by shift-registers controlled by the same fundamental frequency. Each of the several control channels has an individual generator with individual fundamental frequency and frequency divider, and individual filtering and demodulation means at the receiver.
