Title: Digital transmission system for analog data - uses integrator to modulate pulses in width and frequency with analog signal
Inventor: TAKIKAWA TOMOHIRO DIPL ING
IPC: H03K9/00
Filed: 1978-10-19
Abstract: The digital transmission system, for analog data, uses the analog signal to modulate a pulse train in pulse width and frequency. The receiver contains an integrator that forms the arithmetic mean of the pulse train. The transmitter contains an integrator (1) that either integrates the input signal (VIN) together with a positive reference (+VR) or together with a negative reference (-VR) depending on the positions of two switches (S1, S2). The switches are controlled by a comparator (2) that compares the integrator output with either the positive or the negative reference voltage.

Title: Active damping circuit for four wire to two wire changeover - has auxiliary tone generator for constant adjustment of variable damping resistor
Inventor: SCHNEIDER WOLFGANG ING GRAD
IPC: H04B1/58
Filed: 1979-11-29
Abstract: The appts. is for use in telephone systems at points where four wire circuits are connected to two wire circuits. The performance of an active damping circuit comprising two amplifiers (V1,V2) can be improved by adding a tone signal to the first amplifier. A pulse generator (G1) controls an alternating current generator (G2) feeding a signal (U8), typically at 1000Hz, to an input of the first amplifier (V1). This signal is retrieved from the output (U2) of the second amplifier (V2) by a band pass filter (BP1). It is rectified and applied to an operational circuit (NW) which determines the value of the variable damping resistor (R4). The circuit (NW) receives a timing impulse from the pulse generator (G1) and updates the resistor (R4) value at each pulse such that the rectified voltage (U9) from the filter (BP1) is a minimum. In the intervening period, the resistor value is held at the last setting.

Title: Battery-powered drive system for bicycle - has DC motor coupled to tyre of rear wheels via friction roller
Inventor: VOLKRODT WOLFGANG DR ING
IPC: B62M6/75
Filed: 1980-01-29
Abstract: The drive system has a permanent magnet d.c. motor whose output power corresponds roughly to the power produced by the leg muscles of the human body. The motor torque is transferred to the rear wheel of the bicycle via a friction roller pressed against the side wall of the tyre.

Title: Cement mixer flushing water neutralisation - by adding carbon di:oxide under pH value control
Inventor: DAMANN FRANZ-JOSEF
IPC: C02F1/66
Filed: 1980-03-25
Abstract: Waste water from the flushing of concrete mixers and other concrete machinery has an extremely high pH-value and must not be allowed to drain off without treatment. It is passed through a scrubber in which gaseous carbon dioxide is mixed with the turbulent liquid. a pH-meter supervises the alkalinity and keeps the liquid in a closed circuit until the desired pH-value is reached. The flushing water is admitted through pipe to the scrubber where tubular insets keep it in turbulence. Carbon dioxide is admitted through an adjustable control valve from the bottle. A pH-meter causes a control unit to keep an outlet valve near the meter shut so that the liquid circulates in a closed loop until the pH-value is reduced. This is a quick process which saves the expense and space for settling basins.
