Title: Transposing unit altering frequency of electronic organ - uses twelve-key keyboard with each key displacing note by one semitone
IPC: G10H1/20
Filed: 1978-12-11
Abstract: The transposing unit has a 12-key keyboard on the organ's keyboard. Each key is assigned to one of the 12 semitones of an octave and when operated (set) displaces the frequency of the sound produced by an amount equal to the interval between C and the note represented by the key. A foot pedal cooperates with the 12-key keyboard and is used to move the displaced interval along by a given amount e.g. by one half-tone, when none or only one key has been set. The displacement is therefore set using a key and thereafter activated by the foot pedal (first operation of pedal) and then moved on a given amount (second and subsequent operations of pedal).

Title: Magnetic field measurement and stabilisation - using ferromagnetic resonance of ferromagnetic body determined by frequency-modulated microwave oscillator
Inventor: CASPERS FRIEDHELM DIPL ING
IPC: G01R33/389
Filed: 1979-01-24
Abstract: A method of measuring and stabilising magnetic fields involves using the ferromagnetic resonance of a ferromagnetic body such that the resonance max. frequency is a measure of the field strength. Linearity is improved to be less than 1 per cent. Measurement accuracy is thus increased whilst high linearity and low temp. sensitivity are maintained. A frequency modulated microwave oscillator is used for accurate measurement of the max. of the body ferromagnetic resonance. The centre band frequency of the microwave oscillator is approx. equal to the resonance frequency of the body, which is placed in a measurement probe. The ferromagnetic body is a rotation ellipsoid in partic. a spherical, body of yttrium-iron-garnet or of barium ferrite.

Title: Electrophoretic analyser for protein and nucleic acid size determn. - with planar transport in first and transverse transport in second gel layer of diminishing pore size
IPC: G01N27/447
Filed: 1979-08-25
Abstract: An electrophoretic analysis,specially to determine the molecular size of proteins or nucleic acids, is based on a first electrophoretic transport in a first planar carrier layer along its plane. A second transport on an adjacent second layer is in a direction across the plane of the layer. The pore size in the latter is reduced continuously or in steps away from the first layer. A thin planar carrier layer of a gel in homogeneous concn. is in side contact with a thicker gel layer with a pore size hich diminishes outwards. A horizontal louvre grating is fixed by vertical bars which are held together by rubber rings. This simplifies the procedure and speeds it up.
Patent DE-2936646-A1 (DE)
Title: Frequency plan for mobile radio system - gets more channels by replacing some FM channels with two single sideband channels
Inventor: POETTER MANFRED DIPL ING
IPC: H04B7/26
Filed: 1979-09-11
Abstract: The mobile radio system has a frequency allocation plan based on 9 hexagonal areas, each with its own FM channel, grouped together to form a xyz zone. The channels are spaced 20kHz and may be repeated in adjacent zones, no two areas with the same channel being closer than 60km. The number of channels can be increased by replacing some FM channels (1,2,3) with 2 SSB channels each (1-6). The SSB carriers are displaced 5kHz either side of the FM carrier. The lower channel uses LSB and the higher uses USB. Since SSB needs 100km spacing to avoid common channel interference, two zones in which a channel is split into 2 SSB channels must be separated by a zone using that channel for FM. Thus the system operates with a mixture of FM and SSB.
