    摘要： A polyamide-imide precondensate which is solid at room temperature, but is fusible and soluble in polar solvents. It is manufactured by first condensing 1 mole of diamine with 2 moles of tricarboxylic acid anhydride in a diol as the solvent, to give a diimide-dicarboxylic acid, then esterifying the diimide-dicarboxylic acid with the diol and finally effecting the polycondensation by adding 1 mole of diamine per mole of diester. The precondensate may be used, as a melt, as a solution in organic solvents or as an aqueous dispersion, for coating electrical conductors.

    摘要： A process for the electrical insulation of metallic conductors by coating wires with aqueous dispersions of coating materials, comprising the following steps which are carried out in a single cycle: introducing the starting dispersion into a storage zone A; continuously withdrawing part of the dispersion from the storage zone and feeding said part to a dispersing zone, where it is homogenized and comminuted; if necessary, cooling the dispersion to below 40.degree. C in a cooling zone; feeding the dispersion to a fractionating zone D, where it is separated into a coarse fraction and a fine fraction; and finally, passing the fine fraction through coating zones E, through which wires are drawn so as to receive a coating.

    摘要： A device (10) for moving patients who are confined to bed comprises a travelling undercarriage which can be locked in place by means of a locking brake (84), a stretcher support (16) which can be adjusted vertically and laterally relative to the undercarriage (16) and a locking gear (90) for the stretcher support (16). In order to obtain a stabilizing system securing the arrangement against tilting, which is easy to operate, it is proposed to provide a solid block (14) carrying the said vertically adjustable stretcher support (16) which block is carried itself by at least one guide element (34, 36) extending transversely in the said undercarriage (12) in such a manner that it can be displaced in transverse direction between two lateral end positions, with the locking gear comprising stop means which is arranged at the block (14), which can be controlled from the said stretcher support (16) and engaged in recesses provided on the guide element (34, 36) for blocking the relative movement between the block (14) and the undercarriage (12).
