Abstract: The invention relates to a method and an arrangement which are of importance in the polarization of shaped articles from polymers. The shaped articles from polymers, polarized by the method as per invention, are finding effective application in electroacoustic converters, piezoelectric switches and in proving electromagnetic radiation within a broad spectral zone.It is possible to obtain by the method as per invention and, respectively, the arrangement as per invention, above-average values for polarization as well as for the piezoelectrical and pyroelectrical coefficients. The arrangement as described, and respectively, the method as described are characterized by the use of charge-limiting polarization capacitors.

Abstract: An improved process for cold mechanical working of metallic materials is disclosed, in which a lubricant containing salts of carboxylic acids with more than ten, and preferably 15 to 20, carbon atoms. The lubricant also contains at least one organic solvent with a boiling point below 200.degree. C., and preferably at least one organic solvent with a boiling point below 30.degree. C. In a preferred embodiment, tensides are added to reduce surface tension. The lubricant combines the advantages of solid and liquid lubricants, and permits the cold mechanical working of materials with high tensile strength.

Abstract: Is the objective of the invention to develop a process for the production of tagged gibberellin-(7)-aldehydes which is of general applicability. As per the invention a gibberellin-(7)-aldehyde is converted into the gibberellin-(7)-aldehyde tagged at the C-15 position of the basic gibberellin skeleton under the influences of ultraviolet radiation, in given cases after the isolation of a developing 7-Hydroxy-7,15-cyclo butane derivative, and in the presence of compounds with tritium or deuterium donor properties respectively. The process is of particular suitability for the tagging of alkali-sensitive gibberellin-(7)-aldehydes. The tagged gibberellin-(7)-aldehydes produced by the process as per invention, are of importance for instance as primary materials for the obtaining of tagged natural gibberellins and their derivatives.

Abstract: A pulsed-flow apparatus for spectrometers and the like has a mixing chamber and two syringes each adapted to contain a different liquid and both connected to the mixing chamber. The plunger of each syringe has an outwardly extending rod provided with a toothed rack. A pair of electric armatures are provided, each reciprocable lengthwise of one of the rods and carrying a pressure spring which moves with the armature and, during each move of the armature towards the syringe, advances the plunger deeper into the syringe by the length of one tooth of the rack, but does not extract it when the armature subsequently moves in the opposite direction.

Abstract: A spectrometer is disclosed in which gradient coils are provided in order to create an inhomogeneous magnetic field for use in analyzing individual regions within the sample under examination. The gradient coils and the modulating coils are operated by discrete pulses, rather than continuously. A keying unit coordinates the interaction of the various components of the spectrometer in order to monitor resonance of the sample under examination while such pulses occur.

Abstract: Straight chain perfluoroolefins compounds of medium length with terminal or double bonds and a minor proportion of trifluoromethyl side chains or mixtures of such perfluoroolefins with perfluoro paraffins of equal chain length and corresponding structure, the perfluoroolefins being present in the mixture in an amount of 40 to 70%. The compounds are valuable as highly reactive intermediate products in the production of surface active agents. The compounds are made by subjecting a highly fluorinated organic compound to degradation by means of a high energy radiation of a density of 0.3 to 3.0 W/cm.sup.2 effected in a radiation chamber which has been subjected to a preceding rinsing with an inert gas or with a monomeric highly fluorinated organic compound.

Abstract: A process for improving the mechanical properties of martensite curred alloys comprising a cold mechanical working, a heat treatment within specified parameters, and a rapid cooling below 400.degree. C. A continuous process is described which results in material with improved plasticity properties.

Abstract: A metallized polymeric article in which the metal coating is more firmly adhered is provided by disposing between the polymeric substrate and the metal top coat a poromeric adhesive coating. The poromeric adhesive coating is produced by coating onto the substrate a solution or dispersion of a polymer which when coagulated by exposure to an atmosphere of a suitably high relative humidity coagulates to form a poromeric adhesive coating.

Abstract: Method for the preparation of starch hydrolysis products containing mixtures having a dextrose equivalent of 5 to 10 which mixtures have the property of forming together with water, white glossy thermoreversible gels having a neutral taste, which gels are stable to freezing and defrosting and the consistency of which gels may be varied from pasty to cutting hard depending upon the proportion of water contained in the gel, comprising mixing two starch products which in the admixture have an average dextrose equivalent of 5 to 10, the starch products being of respective degrees of polymerization differing from the other by at least ten times and each of the starch products being branched and at least one of the starch products being a starch hydrolysis product.

Abstract: Food additive, having utility for example as a thickener is prepared by mixing an optimum concentration of a starch-hydrolyzing enzyme and a starch or pre-treated starch in water in a concentration of the starch of 15-50% by weight at a pH optimum for the enzyme, heating the mixture to a temperature at which the starch grains swell and permitting the starch to hydrolyze, inactivating the enzyme by additional heating of the mixture, and cooling the mixture to form a gel or dehydrating the mixture to form a dry hydrolyzate.
