Title: Water reactor coolant pump chamber - has low rupture risk due to using near-spherical steel shell segments with external prestressing
Inventor: WIESER RUDOLF DR
IPC: F04D29/40
Filed: 1979-01-04
Abstract: A reactor pump chamber, pref. spherical or ellipsoidal internally comprises hot-formed steel ring-sections, each pref. seamless, welded one to another. The intake ring section, pref. coaxial with the pump, and which may also contain the impellor system, and the section forming the flange at the opening for the pump assembly, may be welded or integral with their adjacent chamber sections. The latter may be integral with each other or be separate hemispherical shells with a joining line which lies obliquely to the pump axis, such that the delivery pipe and the intake section, (both pref. seamless) are each joined to a different 1/2-shell. Pre-stressing cable anchoring ring sections may be mounted over the intake, delivery and pump-entry orifices of the chamber, such that the cables may traverse the chamber external surface horizontally and vertically, with this surface covered by grooved plate for seating the inner of these 2 cable layers. The design allows use of a tough heat-treated steel, the hot shaping of which precludes persistence of cavities. The near-spherical form reduces stress-peaking due to internal pressure. Weld seams can be few and located in moderately stressed positions which allow of simple non-destructive testing methods.
Patent DE-2901124-A1 (DE)
Title: Doppler DF unit with phase deviation compression - uses first and second scanning processes to derive two phase-modulated sum signals, improving signal=to=noise ratio
Inventor: MEINKE HANS HEINRICH PROF DR D
IPC: G01S3/54
Filed: 1979-01-12
Abstract: Using phase-swing (deviation) compression, proposed Doppler direction finding (DF) arrangement is designed to change the interdependency between the DF frequency f and the frequency deviation DELTA fu and the bandwidth B, so that servicing of the arrangement is simplified during change of working frequency, to give optimum signal-to-noise ratio. Thus, to determine the plane of incidence of the electromagnetic wave(s), two phase-modulated sum signals are derived by means of first-an second scanning processes, and are then summated in a gating unit to form a third phase-modulated sum signal whose frequency deviation is different from that of the first and second sum signals. The frequency deviation of the third sum signal is then adjusted by selection of the time shift DELTA t between the first two scanning processes ready for processing in the gating unit to derive the incidence out of the phase modulation of the third sum signal.

Title: Quality testing, esp. of variable loaded test-pieces - subdividing measured variables into sections forming different thresholds
Inventor: CROSTACK HORST ARTUR DR ING
IPC: G01N29/14
Filed: 1979-12-18
Abstract: The analysis of the acoustic emissions is controlled by at least one specific characteristic variable of the test piece. This variable is subdivided into sections. Already analysed acoustic emissions are fed to counters having different thresholds. These counters are controlled by characteristic variables of the test piece which are measured in parallel and the difference quotient is formed from the pair. An amplifier with an a-d converter is used for subdividing the characteristic variables of the test piece into sections. A logic circuit links together several characteristic variables. A differentiating device determines the start and end of the sections and a pulse generator forms control pulses. Reliable results are obtained even when loading conditions vary.
