Abstract: Abstract of the Disclosure The invention concerns a method for the preparation of additives for influencing the electrocrystalline growth in aprotic oxygen- and water-free organo-aluminum electrolyte media.  A compound which contains a sulfonimide or sulfonamide group as the reactable group, preferably, N-benzoylbenzenesulfoni-mide, optionally in the presence of an inert organic solvent, is reacted with at least one organoaluminum compound of the general formula AlR3, where R is an alkyl radical, in the ratio of 1:1 to 1:6.  The additives obtained furnish a bright aluminum coating on metals and conductive materials in direct electro-deposition.

Abstract: The ABSTRACT    A signal repeater is described for relaying information in a two-way communication system superimposed on a power distribution network.  The repeater senses signals passing in either direction in the system, translates the received signal to a different band or group of frequencies, and transmits the frequency translated information.  Provision is made for address-coding the repeaters so that, when connected in several levels, a particular path can be selected through the various levels.  Provision is also made for a signal having priority in a system of such repeaters.

Abstract: Abstract The specification describes a thermal cutting machine for cutting up a continuously cast ingot during operation of a continuous casting plant, comprising a clamping means for entrainment of the thermal cutting machine with movement of the continuously cast ingot. A drive moves the thermal cutting machine along the continuously cast ingot and a cutting burner can be adjusted transversely with respect to the continuous-ly cast ingot and can be driven.  The thermal cutting machine is substantially enclosed by a colling shroud, which only has a few passages for shafts, more parti-cularly of support wheels and furthermore for a drive shaft of the cutting burner holder and for an actuating linkage of the clamping means.

Abstract: ABSTRACT OF THE DISCLOSURE           Air withdrawn from a food smokehouse is divided into two branches.  The air in one of the branches enters a chamber in which is a bladed air agitator.  The chamber includes two water sprays with the water contacting the air and the blades.           From that chamber the air sequentially passes through a cyclone separator and a demister.  The air from the two branches is then recombined.  After being recombined, the air passes through a heater and a humidifier.  Part of the recombined air also may pass through a smoke generator.

Abstract: ABSTRACT OF THE DISCLOSURE           A photographed and developed panchromatic negative film is mounted on an enlarger.  White light will, after passing through this panchromatic negative film, be mised up uniformly in a diffuser.  This mixed-up light will print on panchromatic paper each colored image of cyan, magenta and yellow through each color filter in a fixed grade density of red, green and blue-violet.  Of these printed images the differences between an image at the least visible section and other images will be indicated as an unbalance in the three primary colors.  Then, a color filter for color correction corresponding to this unbalance will be selected.  Next, removing the diffuser from the enlarger, alternatively the selected color correction filter will be mounted thereon. Again, when a panchromatic negative film is printed on pan-chromatic paper, a postive picture that will balance in the three primary colors can be obtained.

Abstract: : La présente invention concerne un procédé de fabrication de l'aldéhyde beta-méthylthiopropionique à partir de procédé de fabrication de l'aldéhyde beta-méthylthiopropionique à partir de méthylmercaptan et d'un mélange gazeux contenant de l'acroléine obtenue par oxydation catalytique du propylène.  Ce procédé comporte deux étapes:  la première consiste dans une absorption du mélange gazeux contenant l'acroléine par l'aldéhyde betaméthylthiopropionique;  la deuxième est la réaction à une température comprise entre 10 et 50.degree.C entre l'acroléine dissoute dans l'aldéhyde beta-méthylthiopropionique et le méthylmercaptan; l'hémithioacétal de l'aldéhyde beta-méthylthiopropionique se formant au cours de la réaction.  Ce procédé est caractérisé en ce que, préalablement à l'absorption, on débarrasse ledit mélange gazeux de l'acide acrylique et de l'eau qu'il contient et en ce que l'on maintient le taux d'hémithioacétal formé dans le milieu réactionnel à une valeur inférieure à 1% en poids. Ce nouveau procédé présente l'avantage de ne pas nécessiter une étape d'extraction.

Abstract: ABSTRACT OF THE DISCLOSURE           A cyclone structure is provided for use in controlling the flow of two fluid streams to create a localised inward radial flow.  The structure includes a chamber having a side wall disposed concentrically about a longitudinal axis and having first and second transverse end walls attached to respective ends of the side wall.  A discharge tube is mounted in the first end wall concentrically about this axis and projects into the chamber.  First and second inlets are provided adjacent the respective end walls and means is provided to move fluid under pressure into these inlets and into the chamber. The fluid enters the chamber in two distinct fluid paths moving vortically about the axis in the same direction of rotation, and the respective energy flow rates of fluid in these paths are comparable.  The paths are generally vertical within the chamber and progress axially towards one another before combining where they meet to create the localised inward radial flow.  Subsequently, the fluid leaves the radial flow and moves axially towards and out through the discharge tube.  A method of providing the radial flow is also described.

Abstract: ABSTRACT:                  In tomosynthesis distortions are produced owing to the curvature of the image intensifier input screen and other non-linearities of the transmission system, which in particular affect the synthesis of the laminar image when the individual images should be shifted relative to each other for this purpose. These distortions depend on the angle which the central ray makes with the laminar plane during the individual exposures and therefore they can hardly be compensated for. The invention now proposes that when the individual images are taken the image intensifier is steered so that the optical axis always remains parallel to the central ray. The distortions produced by the curvature of the input screen of the image intensifier etc. are then independent of the angle between the central ray and the laminar plane, and can be compensated for by known commer-cially available correction devices. However, additional geometric distortion is then produced because the plane of the input screen is inclined relative to the laminar plane.  These geometric distortions depend on the orbit angle.  By a rotation of the deflection field in accordance with the orbit angle, it is then achieved that trapezium distortions are produced which are independent of the orbit angle. These trapezium distortions are compensated for in known manner, and subsequently the position of the deflection field is restored.
