Title: Fuel consumption meter for IC engine - has two pointers turned by speed and load signals, with intersection indicating economy level against reference curve
Inventor: WOESSNER GUENTER PROF DR DR IN
IPC: G01F9/02
Filed: 1978-07-06
Abstract: A tachometer on the engine feeds an analogue signal generator whose output rotates a pointer moving over an engine speed scale. A pressure detector in the intake downstream of the throttle produces a signal proportional to the load. this deflects a second pointer over a scale calibrated to indicate load and fuel consumption per hundred kilometres. The intersection of the two pointers gives an indication of the economy of operation. A line on the instrument marks the locus of the intersection for maximum economy.

Title: Pen recorder control circuit - switches off when paper is absent or damaged using control signal derived from pen to drum resistance
Inventor: MARQUARDT BERNDT
IPC: G01D15/24
Filed: 1978-10-17
Abstract: A circuit for controlling, esp. interrupting, a printer placing measurement data on paper when the paper is damaged or has run out has a rapid response. The control signal is derived from the electrical resistance between the printer printing element and the paper support. The paper drive is interrupted for a min. time following a given delay after the control factor has reached a defined level indicating the absense of paper. If a thermal print element is used the heating power is also interrupted. The paper drive interruption delay time varies with the paper speed. The output of a control voltage comparator drives the pen drive and heater via a flip-flop and OR-gate and the paper drive via a further flip-flop and AND gate.
