Title: Switching of speech channels or groups in carrier systems - uses transposition of basic primary group for adaptation to filter passband
Inventor: BUSSE HEINZ ING GRAD
IPC: H04J1/04
Filed: 1974-10-19
Abstract: The speech channels are adjacent to each other, and the carrier frequency systems generate basic groups by the premodulation method. The basic primary group in the first system is transposed by one of the existing channel carrier so that the channel, or group of channels, to be switched falls into the pass band of a filter whose bandwidth corresponds to that of the channel or group of channels. The band selected by the filter is transposed by the same or another available channel carrier into the required frequency position within the second system basic primary group. Preferably the band passed by the filter is transposed by an auxiliary carrier to the premodulation group frequency.

Title: Motor vehicle fuel consumption meter - integrates pulses from fuel rate and distance recording pick ups for analog display
Inventor: GOERTLER HORST
IPC: G01F9/00
Filed: 1975-03-05
Abstract: The motor vehicle fuel consumption meter comprises two pulse generators - one working from a fuel measuring device (M) and the other from the vehicle odometer (S). Both sets of impulses are used to trigger monostable circuits (MF1, MF2) which produce pulses of constant width and amplitude. The output from the fuel consumption monostable is integrated (I1) and amplified. The capacitor forming part of the integrator staircase generator is periodically discharged by a pulse from the second monostable operating from the vehicle distance recording device. A further resistance-capacitance integrator (I2) with amplifier (V2) DC-restores the signal for a moving-coil instrument (M1). This can be calibrated to indicated fuel consumption in Litres per hundred Kilometers, for example.
