Patent DE-2949582-A1 (DE)
Inventor: DUIFHUIS HENDRIKUS
IPC: G10L25/03
Filed: 1979-12-10
Abstract: Method of and arrangement for the determination of the pitch of speech signals in a system of speech analysis, wherein sequences of significant peak positions of the amplitude spectrum of a speech signal are derived (13) from time segments of the speech signal by means of a discrete Fourier transform (12). In order to reduce the influence of noise signals and noise components, respectively, in the amplitude spectrum the significant peak positions are compared with different masks (15), which have apertures at harmonic distances of the associated fundamental tone. The mask which matches the sequence of significant peak positions best is selected (20). A probable value for the pitch is now computed with the harmonic numbers now known of the significant peak positions which are located in apertures of the selected mask. The mean square error between these significant peak positions and the corresponding harmonics of the finished tone can be used as a criterion (21).

Patent DE-3024387-A1 (DE)
Inventor: SUSZ CHRISTIAN
IPC: G04B37/22
Filed: 1980-06-26
Abstract: Iridium in a proportion of 0.2 parts per thousand and cobalt in a proportion of 3 parts per thousand are added to a gold alloy containing 750 or 585 or 375 parts per thousand of gold, the remainder being silver and copper, or only one of these two elements, and optionally zinc. This has the effect of limiting the mechanism of growth of the grains of the alloy during subsequent heat treatments to which the alloy is subjected, with the result that the mechanical properties of the latter, when used, are improved. The diagram shows that the mean diameter of the grains of a standard alloy (curve St) after 150 min of annealing at 730 DEG C is 0.3 mm, that that of the grains of this same alloy but with 3 parts per thousand of cobalt (curve X110) is 0.225 mm, that that of the grains of this same alloy but with 0.2 parts per thousand of iridium (curve X109) is 0.175 mm, while that of this same alloy with 0.2 parts per thousand of iridium and 3 parts per thousand of cobalt (curve X98) falls to less than 0.1 mm, in all cases after 150 min of heat treatment at 730 DEG C. <IMAGE>

Title: Low energy requirement desalination plant - uses mechanical compressor driven by steam turbine to process vapour from evaporator
Inventor: EDLER WILHELM
IPC: B01D1/26
Filed: 1980-07-18
Abstract: In the single- or multi-stage evapn. of aq. liqs., esp. for producing fresh water from sea water, the liq. is preheated by a heat exchanger and fed to an evaporator where it is partly vapourised. The vapour is sepd. from the liq. and compressed by a mechanical compressor either directly or after passage through a series of evapn. stages, with the non-vapourised liq. residue removed after the last stage. The compressor is driven by a steam turbine. The vapour pressures after the compressor and after the turbine are brought to the same level, and these two vapour streams are combined for introduction into the first evapn. stage for heating. The method involves no electrical mains supply for the compressor, only the compact turbine. Over 30% of the energy consumed by conventional methods is saved, and the distillate is of high purity.

Patent DE-3029311-A1 (DE)
Title: Cycloconverter for motor drive - uses three single phase units with signal superimposed on current control to maintain voltage symmetry
Inventor: SALZMANN THEODOR DIPL ING
IPC: H02M5/27
Filed: 1980-08-01
Abstract: The control system assists in maintaininq voltage symmetry in the three phases of the load without requiring a voltage feedback from the machine or the converter neutral point. This eliminates the need for high voltage connections and potential transformers. Each phase of the cycloconverter has independent current control with a reference for each regulator. In order to prevent divergence of the phase voltages the output voltages of the current regulators are summed inverted, compared with a null point reference, typically zero, smoothed, and applied as a secondary reference modifying signal to the summing junction of each current regulator. The proposed system can be used on converters giving a sinusoidal output. With small modifications it can also be used for cases where a trapezoidal machine voltage is required.
