Title: Correction method for data signal modulated on carrier - is for signal distorted by linearly distorting transmission medium
IPC: H03H15/00
Filed: 1973-07-12
Abstract: The received distorted signal r(t) is subjected to a transformation during which a quadrature signal r(t) of the original signal is produced; and two signals y(t) and y(t) are obtained by filtering from the above two signals. The signals are subjected to convolution operations by two filter transmission characteristics and the two signals values y(t) and y(t) are obtained. The original received signal r(t) is applied to two filters with transmission characteristics h1(t) and h2(t) while the quadrature signal r(t) is applied to two further filters with transmission characteristics h2(t) and h1(t). The output signals from the first and third filters are added to produce the first of the two signals (y(t)), and from the second and fourth filter to produce the second signal ( y(t)).

Patent FR-2245961-A1 (FR)
Title: Selective attenuation of multiple reflected seismic signals - enables correct interpretation of recordings of earths crust
IPC: G01V1/36
Filed: 1974-04-24
Abstract: The correct interpretation of seismic recordings of the sub-surface of the earth's crust is often limitted by the multiple reflection or echoes which appear on the traces. The effects are reduced by selective attenuation of these reflections. An initial estimation (8C) of a seismic signal (S1) is obtained by operating on the trace with a Wiener prediction filter (8B). This enables the determination of time and amplitude corrections (8D) necessary to optimise the agreement between the predictions and actual traces during several time intervals. The predicted and actual signals are then compared (8E) during the same time intervals. The correction signals (8F) are subtracted (8G) from the actual signal to obtain the required processed signal (S2).

Title: Permanent magnet D.C. motor - uses radial bar machines with disc rotor carrying axial pole pieces
IPC: H02K25/00
Filed: 1974-05-17
Abstract: The stator of this DC motor comprises permanent magnet bars disposed radially about the axis of the motor. The rotor is formed from a disc that rotates between the radial magnets. The magnets have a gap in the radial direction and soft iron pole pieces attached to the disc rotate past the permanent magnet poles that are thus formed. The soft iron poles are magnetised by coils connected to a collector system. This provides a motor that can be mass produced and have a range of output powers that are dependent upon the number of bar magnet combinations.
