Title: Fuel consumption evaluation system for IC engine - has rotating probe in pipe with initiator and memory
Inventor: HANNEFORTH HEINRICH
IPC: G01F9/00
Filed: 1978-07-19
Abstract: The internal combustion engine has a system for determining evaluating and indicating the fuel consumption. It can be installed in existing engines. The volume of fuel consumed as well as the distance that can be achieved with the remaining amount of fuel are also indicated. The measuring element (2) is inserted in the fuel pipe (1).

Title: Adaptive filter in sound reproduction system - has corrector output fed to amplitude demodulator, providing control as function of terminal frequencies of useful signal components input
Inventor: IZAKSON ILJA SEMENOVITSCH
IPC: H03G5/18
Filed: 1978-07-31
Abstract: The adaptive filter reduces the noise signals in radio appliances used for recording and reproducing sound. The filter consists of a series connection of an algebraic summing unit to shape a control signal, a weighted filter to convert the signal spectrum, a minimum noise limiter, and a frequency corrector. One input of the summing unit is connected to the input of a controlled filter, and its second input goes to the output of the controlled filter. The output signal of the frequency corrector is passed to the input of an amplitude demodulator. This enables the pass band of such radio applications to be controlled as a function of the terminal frequencies of the useful components of the input signal.

Title: Mercury drop formation device for polarographic measurement - enables drop size regulation by varying capillary valve opening time
Inventor: KONIAS HUGO DIPL ING
IPC: G01N27/34
Filed: 1978-10-05
Abstract: The device for polarographic measurements on suspended mercury drops enables examination of electrode reaction products and special analysis. The device is produced with less demanding and expensive processes than required for types using a micrometer screw piston adjustment and does not suffer from leakage problems associated with them. The capillary tube on the end of which each drop is formed has a component contg. a tap or transferse blocking valve wiht an electrical or mechanical control. This interrupts the mercury flow when it is open the mercury flows at a rate dependent on the capillary dimensions. The size of the drop can be regulated by varying the valve opening time. A new drop is formed by tapping the device until the old one falls off and reopening the valve.

Title: Colour carrier conjugated composite signal circuit - comprises comparator of halved colour carrier frequency sawtooth signal and phase setting signal
Inventor: SCHUSTER WILHELM DIPL ING
IPC: H04N9/45
Filed: 1979-03-31
Abstract: The conjugated composite colour carrier signal is derived by a circuit comparing the sawtooth signal of halved colour carrier frequency with the control signal for setting the phase of the conjugated signal. The resulting signal has a doubled frequency, and the even line periods are discriminated against the odd control signals using a reference d.c. voltage. The colour carrier signal is fed to the frequency divider which is connected to the function generator providing the halved frequency sawtooth voltage. The latter is transmitted to the comparator whose other input receives the control signal for stepless phase setting of the conjugated composite colour signal. A switch selects the d.c. reference voltage and control voltage from a potentiometer.

Patent DE-3040255-A1 (DE)
Title: Tyre balancing device with test stand - has measuring device detecting tyre out-of-balance and sync. circulating equaliser, coupled to tyre
Inventor: GNADLER ROLF PROF DR ING
IPC: G01M1/22
Filed: 1980-10-24
Abstract: The balancing is carried out on a tyre testing stand which has measuring gauges for detecting an out-of-balance of the rotor w.r.t. the position and magnitude at a random rotor speed. To the rotor to be balanced is coupled a synchronously circulating equalising body with several liquid chambers distributed round its periphery. The chambers are proportionally filled or discharged by a control device responding to the position and magnitude of the measured out-of-balance condition. The out-of-balance measuring gauge is stationary and is mounted in a given radial direction w.r.t. the equalising body. The component of the out-of-balance signal in this direction is thus measured, with the output signal being sinusoidal. A sine function generator may be used for this measuring, generating a sine function, synchronously circulating with the rotor, which starts with a specified radial beam. The equipment includes a comparator.
