La distillation est effec-tuée sous une pression réduite telle que la température d'ébul-lition des mélanges à la base de la colonne à distillation ne dépasse pas sensiblement 85°C.  La durée de séjour de la phase liquide dans la colonne ne dépasse pas une demi-heure.  La quantité d'agent acide ou basique est généralement comprise en-tre 0.01 et 5% en poids du mélange réactionnel total.  L'agent basique est choisi, de préférence, parmi les hydroxydes ou les carbonates des métaux alcalins ou alcalinoterreux et l'agent acide parmi les hydracides ou les oxyacides minéraux courants.          Le procédé selon l'invention a pour but de limiter considé-rablement l'hydrolyse des cétazines en ajustant le pH du milieu tel que ci-haut mentionne et d'en faciliter la séparation par le fait même.

Abstract: ABSTRACT OF THE DISCLOSURE         A test apparatus for checking test objects, such as protective relays, especially voltage, current and/or frequency relays for the protection of a generator of a power supply network comprising a first circuit for generating and con-verting test signals or magnitudes to be delivered to the test objects and a second circuit for pre-programming the test signals or magnitudes to be delivered to the test objects.     The first circuit comprises a first test signal generating circuit for supplying the voltage relay and the current relay with voltage and current test signals, respectively, and contains a first secondary winding of a test transformer.  A static potentiometer is connected in parallel with this first secondary winding.  The potentiometer supplies test signals in finely stepped or graduated values to the test objects.  The first circuit further comprises a second test signal generating circuit for supplying the frequency relay with frequency test magnitudes.  The second circuit embodies a test matrix composed of intersecting electrically conductive rails.  The test matrix stores information concerning the test signals to be delivered to the relays.  A signal and control device operatively connected with the test matrix and receiving therefrom the stored information concerning the test signals stores a pre-determined course of the test program and correspondingly con-trols the performance of the test.

Abstract: A B S T R A C T            The invention is concerned with the recovery of relatively pure magnesia from magnesite which is normally contaminated with too much silica and silicates to permit the magnesite simply to be calcined for the recovery of refractory grade magnesia. The magnesite in its raw uncalcined state is treated with SO2 at elevated temperatures preferably between 50 and 60°C thereby rapidly dissolving a high proportion of magnesium as magnesium bisulphite without the cost of initial calcination and without dissolving above about 1% of SiO2 present in the magnesite.   The solution of magnesium bisulphite can thus be purified by filtration and magnesia may be recovered in known manner from the purified solution.

Abstract: MULTIWAVELENGTH LIGHT BEAM DEFLECTION AND MODULATION             Abstract of the Disclosure Apparatus and method are disclosed for diffracting light beams of different wavelengths to form a color image without achromatizing optics.  An acoustic wave deflection frequency range is utilized which will result in no more than a predetermined maximum variation of diffraction efficiency and which covers the Bragg-tolerance ranges for all wavelengths used. Because the different wavelength beams will scan at different speeds (covering the same angular deflection during different scan times) intensity modulating information for each wavelength is impressed upon an acoustooptic modulator in the light path at different appropriate rates and during different appropriate periods during the scan.  The modulating information for each wavelength is impressed upon the modulator only during that respective time period in which the deflection frequency is within a range that will result in angular diffraction ranges which match for all beams.

Abstract: ABSTRACT OF THE DISCLOSURE         An on-axis, optical head-up display device, for use in fixed installations, vehicles or aircraft, utilizes a single block of transparent acrylic with the upper surface curved end coated to form a collimating mirror. The block itself is comprised of two major portions cemented together with a transparent  bonding material wherein the resulting interface forms a combining surface.   A generated image is transmitted from the focal plane of the collimating  mirror upwardly through the combining surface; then it is reflected downwardly  by the collimating mirror back to the combining surface which in turn serves to combine  the generated image with a background view.   The combined image is viewed by an observer through a back window of the block. Optical aberrations are reduced by extending  the material of the block to the focal plane of the  collimating mirror where an image generator is located.
