Abstract: ABSTRACT OF THE DISCLOSURE                 A method of increasing the signal-to-noise ratio of a time-dependent scanning signal produced during a periodic scanning operation wherein a defined or bounded and centered field is scanned line-by-line by means of a scanning device, there is produced a time-dependent supplementary or additional signal corresponding to the spacing of the momentarily scanned location from the center of the field and possessing a momentary value r as well as a maximum value R.  Successive line scans occur in directions which in each instance differ from one another by a pre-determined angle in such a manner that as a function of the line width the neighboring lines successively adjoin one another at the field boundary and within the field partially overlap and at the field center completely overlap.  From the scanning signal there is produced a multiplicity of primary signals forming a sequence, which in this sequence possess a stepwise time-delay which in each case increases by a period of the line scanning.  From the supplementary signal there is produced a multiplicity of auxiliary signals, a respective auxiliary signal is multiplied in a respective multiplier with a respective associated primary signal for producing a respective intermediate signal, and the intermediate signals are summated in an add?r for producing an output signal.

Abstract: A DEVICE FOR AMPLIFYING A LASER PULSE     DELIVERED BY A LASER OSCILLATOR                   Abstract of the Disclosure A light-amplifying medium is pumped by an auxiliary excitation source and has a number of energy levels, the laser transition being intended to correspond to the laser pulse delivered by the oscillator and to take place between the upper laser level and the lower laser level.  Mirrors placed around the amplifying medium reflect the laser pulse from one mirror to the next so that the time interval between two successive pulse traversals within the amplifying medium is longer than the time of population transfer between on the one hand the upper reserve level and the upper laser level and on the other hand the lower laser level and the lower reserve level.  The amplifying medium is thus regenerated by population exchange at the lower and upper levels between each pulse traversal through the amplifying medium.

Abstract: SEPARATION OF LIQUID MIXTURES     Abstract of Disclosure Herein are disclosed an improved method and apparatus for separating a mixture of liquids of differing volatilities by fractional distillation in a plate-type apparatus.  Plates consisting at least in part of a porous structure having cap-illary-type passages extending between openings on one side of the plate and openings on the other side of the plate are employed.  The capillary-type passages are adapted to be wetted and filled at least in part by the liquid condensate resulting from the condensation of a vapor mixture, with the consequent formation of menisci in the capillary-type passages and the generation of capillary pressures that cause the condensed liquid to be lodged within the capillary-type passages and transmitted through the plate while preventing the passage of vapor.  A vapor mixture produced by boiling the liquid mixture is brought into contact with one side of the plate containing capillary-type passages, where the vapor mixture is substanti-ally condensed in and near the adjacent openings of such pas-sages, and the condensed liquid is transmitted through the passages to the other side of the plate where it is boiled substantially in and adjacent to the openings of such passages.          The capillary pressure differential required to cause the condensed liquid to flow is produced by the boiling of the con-densed liquid, and the heat required for such boiling prefer-ably is obtained at least in substantial part by conduction of the heat of condensation through the plate.  One or more sep-aration stages can be employed, and plate efficiencies (Murphree) of 100 per cent or more are obtainable.
