Title: Superconductive device for measuring small magnetic fields - has quantum interference device and sample-and-hold circuit to stabilise field working range between Josephson elements
Inventor: GUTMANN PETER DIPL ING
IPC: G01R19/00
Filed: 1977-04-04
Abstract: The appts. is for measurement of small magnetic fields, magnetic field gradients, electric currents and voltages is based on a D.c. superconducting quantum interference device (SQUID). A typical arrangement includes an a.c. source (1) which feeds a sawtooth waveform current to a SQUID. A voltage proportional to this current is fed to the input of a sample-and-hold circuit. When the maximal superconducting current is reached, a voltage change of the order of several millivolts is fed without delay to a differentiating circuit which suppliejs a voltage pulse to the sample-and-hold circuit. During this short time interval, the circuit stores a voltage (U1) proportional to the maximal current. By means of a voltage-current converter, a regulating current is generated and fed to the magnetic field to stabilise the working point. The magnetic field under control (F) is between two Josephson elements (J1, J2).
Patent DE-2720666-A1 (DE)
Inventor: BUNGE ERNST DIPL ING
IPC: G10L15/00
Filed: 1977-05-07
Abstract: For sound analysis, especially for speaker identification, a long-term spectrum is often formed from the recorded signal and compared to a long-term spectrum of a previously recorded signal. When the signal is, for example, received over telephone lines the transfer function thereof may distort the received signal to such an extent that identification is impossible. It is now proposed not to use the long-term spectrum for identification but rather its change, that is to say to accumulate the difference between two consecutive short-term spectra or the difference between such short-term spectrum and the long-term spectrum and to divide this accumulated value by the long-term spectrum in a Divider. Since the numerator and denominator each contain the frequency-weighting factor (aJ) of the telephone line transfer function, this factor is effectively cancelled out by virtue of the division operation performed in the Divider thereby eliminating the effect of the unknown transfer function. As a result the influence of the transfer function of the transmission path disappears almost completely.

Title: Security check for data received by automatically controlled vehicles - uses data telegrams which have test words compared in receiver with word previously recognised
Inventor: MAATJE HENRI DIPL ING
IPC: B61L27/04
Filed: 1977-06-10
Abstract: The vehicle exchange data telegrams with a fixed control station, transmitted by bits in series and consisting of equally long words. Vehicle receivers are tested by special test words, all the bits of which change from one test word to the next. A test circuit is allocated to each receiver, which delivers an error signal when at least one bit of a test word is not different from the corresponding bit of a previously received test word. Test words are transmitted in the data telegrams in place of such data words which are not just used for the vehicle control. A typical data telegram comprises 10 words each of 8 bits length, the first word (A) being a vehicle address, the next eight groups (D1, D2...) comprising the information and the last word (R) being a redundant unit.

Title: Determn. of variables in photometric measurement of enzyme reactions - involves forming sum function and finding the minimum of the sum of squared errors
Inventor: HARTKE DIETER DR
IPC: G01D1/00
Filed: 1977-09-12
Abstract: The didependent variable is e.g. time, position, etc. The measured variable collected from any detector, affected by some error, is applied in the form of an electric variable to a voltage into pulse train convertor, whose output is connected to an input of a logic gate. The gate other input is connected to a time base control, so that the gate output signal, possibly after division, is applied to a counting and display device. The measured variable is determined after forming the sum function and taking into consideration the method of the minimum of the sum of squared errors, by linking of partial integrals, and after using all measured variables present in the measurement interval. Depending on the requirement, small deviations from the minimum of the squared error method are permissible.
