Title: Transmission system for multiple step digital signals - consists of number of equal bit trains combined into one bit train of higher repetition frequency
Inventor: MOEHRMANN KARL HEINZ DIPL ING
IPC: H04L25/03
Filed: 1976-05-20
Abstract: The digital signal consists of a combination of 2n binary signal currents and is produced by a scrambler on the sender side, and recovered at the receiving end by a descrambler synchronised by a transmitted code. The scrambler and descrambler consist of modulo 2 adders and controlling them N shift registers in similar quasi-random generators. A modulo 2 adder (M1, M2) is allocated in the signal path at the sending (SS) and receiving (SE) and to each of the 2n binary signal currents (sig 1, sig 2). It is controlled by one of the 2n outputs of the respective quasi-random generator (QZGS, QZGE). Mutual phase shift between the 2n equal trains at the 2n outputs of the quasi-random generators is such, that nesting of their bits leads to a quasi-random train with the same method of formation but with a repetition frequency 2n times higher.

Title: Reference signal oscillator for stereo radio decoders - uses binary divider and shift register to suppress third harmonic of traffic broadcast pilot tone
Inventor: GAY MICHAEL JOHN
IPC: H03D1/22
Filed: 1976-04-08
Abstract: The reference signal oscillator for stereo decoders provides suppression of input signals which are third harmonics of the 19 kHz pilot tone. Such frequencies are used as identification signals in traffic broadcasting. The voltage-controlled oscillator of the phase-locked loop in the decoder, is fed from the phase-detector and DC-amplifier (71). The 228 kHz output signal drives a binary divider (72) whose complementary outputs are connected to a shift-register (74). The shift-register is a Johnson-counter which delivers 12 phase-shifted outputs. By suitable combinations of outputs to the inputs of two Exclusive-or gates (84, 86), 38 kHs output signals are available which are free of third harmonics of the 19 kHz signal, and other harmonics. 19 kHz signals can be obtained by connection of two Nand gates on the outputs of the shift-register (90, 91).

Title: Transfer mechanism for ultrasonic inspection head manipulator - esp. for reactor pressure vessels, facilitating operation, reducing downtime
Inventor: FIGLHUBER DIETGER DIPL ING
IPC: G01N29/265
Filed: 1977-03-18
Abstract: An inspection installation for the external examination of pressure vessels, esp. for the ultrasonic testing of the welded seams of reactor pressure vessels, has an annular cavity between the vessel and an enclosing wall some distance from it. The wall is biologically protective shield and in the cavity formed by it, there is an arrangement of guide rails on which a manipulator for the ultrasonic inspection head is moved up and down to follow testing paths in the zone of the outer wall of the pressure vessel. An upper section of the guide rail arrangement which is accessible radially from outside, pivots on a shaft at its lower end. This section forms an integral part of a transfer carriage on which it is free to pivot. The pivoting section of the guide rail arrangement can be run on to the upper end of the fixed section of the guide rails, in a transporting postion in which, the pivoting section is swung out of the vertical into the horizontal for transfer, together with the manipulator, radially from outside inwards, and vice versa. From the intermediate position, the pivoting rail section and the manipulator can be lifted into the working position in which it is rigidly coupled to the fixed vertical section, and vice versa. In its working position the pivoting rail section forms an extension in line with the other guide rail section so that the manipulator can cover the whole surface available. The manipulator can be positioned in much less time and with less effort on to the guide rails in the inspection position and removed from there to another point, without the necessity of an overhead crane. The downtime required for the inspection is reduced considerably and the positioning of the manipulator into the inspection cavity is to a high degree automatic.
