Patent DE-2725026-A1 (DE)
Title: Inductive flowmeter with windings energised by AC - is switched at multiple of energising current frequency in synchronism with clock generator
Inventor: BUSCHMANN HEINZ
IPC: G01F1/60
Filed: 1977-06-03
Abstract: A measuring tube (11) has two diametrically opposed measuring electrodes (12, 13) with energising coils (14, 15) disposed between them. The output voltage from the measuring electrodes is fed to an amplifier (16) which drives a conventional indicator device. The energising coils are fed from an alternating current source (17). The energising current is controlled by a switching circuit (22) in synchronism with a clock generator (21) which operates at a frequency which is a multiple of the energising current frequency. The switch (21) also feeds the output of the amplifier (16) alternately to two memories (23, 24). The stores signals are passed simultaneously to a comparator (25) whose output is fed to the indicator device (27) through a current/voltage converter. An integrating circuit (28) is connected between the comparator and the converter which has a null point setting device.

Title: N-channel memory FET with floating memory gate - charged by programmed channel injection has p-zone on drain zone
Inventor: ROESSKER BERNWARD DIPL ING
IPC: G11C11/24
Filed: 1977-12-30
Abstract: n-Channel memory FET ahs a floating memory gate, in which the charge is changed by programmed electron-injecting channel injection, and a control gate, with capacitive effect on the memory gate, as in DT 2445137, esp. for programmed memories of telephone systems. Improvement is that a p-doped auxiliary zone is formed on the drain zone, forming a diode in series with the source-drain section. The drain zone potential floats, the drain terminal being connected to the auxiliary zone and the entire source-drain current always flowing through the auxiliary zone to the drain terminal. Device can act as memory cell without additional selective FET and without complicated forming of both gates. Also, the application of laps to the control gate allows improvement of electrically controlled erasure.

Title: Additional weighing-out indicator - consists of transparent rotating null and marking scales for analogue display balance
IPC: G01G15/02
Filed: 1978-11-25
Abstract: An indicator showing the wt. of goods removed from a balance with an analogue display is a separate rotary scale showing goods weighed out from a quantity originally placed on the balance without requiring calculations to be made. Two transparent scales (6, 7) are individually mounted centrally w.r.t. the viewing window (3) covering the indicator of the balance so as to rotate. One (7) has wt. numerals and the other (6) only a null marking. Alternatively, the scale with the null marking only may be used, in which case it carries markings for the wt. of goods removed. If both additional scales are used they can be clamped so that they rotate together. The null scale is set to the indicator position and the other scale clamped with the desired weighing-out quantity adjacent to it.

Title: Electronic internal illumination delay timing circuit - uses transistor logic to switch=off electric lamps after time delay is set by screw-type turn-pin
Inventor: WIMMELMANN HARALD
IPC: B60Q3/02
Filed: 1978-12-16
Abstract: The electronic internal-illumination-delay circuit in the new "COS-MOS" logic is designed for all motor vehicles with a 6 or 12 volt battery with a negative earth and physical control of the internal-illumination electric lamp.

Title: Frequency divider which divides input by real number - can be set using bcd signal without conversion
Inventor: POL RONALD VAN DER DIPL ING
IPC: H03K23/66
Filed: 1979-01-15
Abstract: The frequency divider has BCD-settable, cascaded digital components. A control loop is located between the frequency input and the frequency output in order to pass the frequency input via a frequency comparator and cascaded N-divider. A feedback path contains rate multipliers and is connected to the output of the N-divider and the actual-value connection of the frequency comparator. Discrete components are used for the frequency comparator, the N-divider and the rate multipliers; alternatively, these functional units may be realised as integrated circuits -- MSI or LSI circuits. The feedback path passes through rate multipliers (K1,K2,..Kp) which form the coefficients in the equation for the return frequency ft given by fb/fa = k1.10-1+k2.10-2+..kp.10-p where p is the number of rate multipliers.
