Abstract: The present invention concerns a novel jelly confection, and more particularly a chewy sweet or a chewing gum comprising a gelatinising agent providing said sweets with the chewiness of same. More particularly, the present invention concerns a novel jelly confection containing little or no gelatin. The present invention also concerns a method for preparing such a confection.

Abstract: An intercalation compound of general formula Na.sub.x K.sub.1-X Z.sub.y, wherein Z is a carbon or a polymer with a cyclic, particularly aromatic unit, as base unit; 0<x<1; and 2.ltoreq.y.ltoreq.6. A method for preparing the compound is also described, as well as the use thereof, particularly in pyrotechnics and in lithium batteries.

Abstract: The present invention concerns a device for the transfer and in-situ reactions under a controlled atmosphere, of specimens for transmissive electron microscopy, characterized in that it is additionally provided with a means (7) for guiding and locking in transport and analysis positions of the rod (1) provided with the grid holders (2), the said rod (1) being advantageously integrated by screwing with the corresponding end of the traction bar (5) which is guided in the cover (3), of which the opening (9) of the front part (3') of lesser diameter is extended over a portion of the length of this front part (3'), on both sides, by longitudinal grooves (10), the said front part (3') being connected to the rest of the cover (3) by screwing of a shouldered portion (11), a gasket (13') effecting the sealing at the level of the screwed assembly.

Abstract: The present invention relates to a heterogeneous anionic polymerization process, catalysed by a metallic insertion graphitic compound. According to the invention, the alkaline metal chosen for the insertion compound is lithium, and the insertion compounds are of binary or ternary type; in the latter case, the insertion compound may comprise an aromatic hydrocarbon also inserted within the graphitic structure. The invention relates in particular to the homopolymerization of butadiene or isoprene, and to the copolymerization of isoprene-styrene.
