Title: Linear A-D converter using successive subtraction - uses amplifier simultaneously as comparator to simplify cct
Inventor: HEYMEL GERHARD DIPL PHYS
IPC: H03M1/00
Filed: 1975-05-14
Abstract: The linear analog/digital converter uses successive subtraction of simple construction without comparators. The amplifiers in the section coders, realised as inverting operational amplifiers (Vj) are designed as polarity separating amplifiers with two summation resistors in the input circuit, one resistor (R1) between the inverting input of the operational amplifier and the input of the section coder, and the other one (R2) from the inverting input through a change-over switch (Sj) which is normally connected to reference voltage and can be switched to earth. The feedback loop for signals of a polarity to be doubly amplified contains a decoupling diode (D1) and a resistor (R4) of twice the value of that between the operational amplifier and input. The other feedback loop has a decoupling diode (D2) and a limiter (Di) limiting the digital output voltage to the logice level of the digital switching circuit in use. The digital output connected to the control input of the changeover switch lies between the decoupling diode and the voltage limiter. This has the effect that the double-gain amplifier is used simultaneously as a comparator.

Title: Scanning of tilted sample by raster electron microscope - avoids parallelogram distortion of image by sufficiently rotating raster
Inventor: HIEKE EDUARD DIPL ING DR
IPC: H01J37/28
Filed: 1975-09-25
Abstract: The tilted sample is mechanically rotated in one step, so that its slope angle is constant, and the x2 direction, in which the electrom beam is deflected, coincides with the x1, direction of the sample. An electric raster rotating device is now turned through the angle delta in the same direction, until the x2 direction is rotated w.r.t. the direction x1 by the same angle as the y2 direction corresponding to the beam advance differs from the y1 direction of the sample. The angle delta is derived from the measured working distance and the sample angle of inclination alpha. The sample is then rotated back until the sample x1 direction coincides with the beam x2 direction, and the sample y1 with the beam y2 direction.

Title: Rollover circuit for electronic keyboard - synchronises cycle register output with key signal using clock activated by inhibiting key signal
Inventor: TAGUCHI TAMIO
IPC: H03M11/20
Filed: 1976-02-12
Abstract: The circuitry gives a keyboard input for electronic calculators etc. a roll over facility, so that information from keys depressed during overlapping time periods can be registered. An input circuit produces a serial key signal. A cyclic register of preset period produces a delayed output which is combined as an inhibition signal with the key signal, and activates a clock. A further circuit connects the input circuit, clock and cycle register. It uses the clock output to enter the key signal into the cycle register a preset time after the clock is activated. The output signal of the cycle register is thereby synchronised with the key signal.

Title: Water and river water treatment - by aeration on system around ship propellers and cooling channels for nuclear power plants, providing ozone or hydrogen peroxide addn.
Inventor: HANSCHMANN HORST
IPC: C02F1/72
Filed: 1976-09-23
Abstract: System bubbles air through the water to transport heat from the lower parts of the surface and purifying it by adding O3 or H2O2. A ship's propeller is surrounded by a perforated cylinder, which itself is surrounded by an unperforated cylinder to form a chamber into which air is pumped. The water suction end is covered with a wire mesh and the discharge end has a downwardly deflected, adjustable aperture to direct the water and bubbles flow. For nuclear power plants, river water is conducted through concentre channels containing a finned tube at the bottom and perforated, pressurised air tubes discharging into the water to produce bubbles. This cools the water before it is returned to the river. For fresh water CO2 is added to the air to activate the adjacent land. Near the sea aluminium roofs (or polyester roofs with metal cooling) over the channels have star-shaped cooling ribs on the top with radial air turbines driven by electric motors and axial suction turbines to supply them. Reflected UV radiation is used to enrich drinking water combined with O3 or H2O2 to render chlorination unnecessary.
