Abstract: A foldable flexible assembling of cells for a lithium-ion battery including: a separator containing an electrolyte; a series of n physically separated negative electrodes located on the first side of the separator and a series of n physically separated positive electrodes located on the second side of the separator; a first current collector including a layer covering continuously the series of negative electrodes so as to ensure electrical connection between all the negative electrodes; and a second current collector including a layer covering continuously the series of positive electrodes so as to ensure electrical connection between all the positive electrodes.

Abstract: Implantable device (8) comprising:—a base element (1; 7);—a cover (2) attached to said base element (1; 7) so as to define a cavity arranged to receive an electronic device (4);—a metallic interlayer (3) disposed between the base element (1) and the cover (2), and arranged so as to bond the base element (1; 7) to the cover (2), wherein said metallic interlayer (3) comprises at least one diffusion barrier layer (3a) and at least one bonding layer (3b). The diffusion barrier layer (3a) may optionally also serve as an adhesion layer, or a further adhesion layer may be provided.

Abstract: An apparatus for simulating the effect of a living organism on the change in shape, the disintegration and dissolution behaviour and the active-ingredient release of a pharmaceutical dosage form, including a beaker-shaped container for accommodating a test medium and the pharmaceutical dosage form and an agitating device for agitating the test medium, which agitating device can be moved periodically in a reciprocating movement into and back out of the container, wherein the agitating device includes a piston-shaped head portion arranged on a piston rod, which head portion is provided with through-openings for the test medium and the distance of the piston-shaped head portion from the container floor can be altered periodically in accordance with the periodic reciprocating movement of the agitating device, wherein, the piston rod is suspended from a gallows-shaped boom or the piston rod passes through a bore in the gallows-shaped boom in such a manner that downward movement of the piston-shaped head portion ar

Abstract: A material in the form of a film is described which contains, in an orientated arrangement which does not display point symmetry, compounds of formula I ##STR1## wherein X is .dbd.CH-- or .dbd.N--, R.sup.1 is C.sub.12 -C.sub.30 -alkyl, R.sup.2 is hydrogen or C.sub.1 -C.sub.30 -alkyl, R.sup.3 is --NO.sub.2, --CN, --CF.sub.3, --COCF.sub.3, --SO.sub.2 CH.sub.3 or --SO.sub.2 CF.sub.3, R.sup.4 is hydrogen or is defined in the same way as R.sup.3, R.sup.5 is hydrogen or --NR.sup.6 R.sup.7 and R.sup.6 and R.sup.7 independently of one another are hydrogen or C.sub.1 -C.sub.30 -alkyl, it also being possible for any of the alkyl radicals to be partially fluorinated or perfluorinated.The compounds of formula I can be arranged in Langmuir-Blodgett layer systems. Such systems can be used for example for the manufacture of opto-electronic units.

Abstract: Two flanges form together with an outer tube a sealed-off casting mold for applying an envelope to a pipe at least part of which is lodged in the mold. The lower flange is equipped with a feed-in duct system and the upper flange with an air-escape and overflow duct. The flanges consist of a material of rubber-like elasticity.The duct system of the lower flange comprises a radially extending bore which opens in an annular distributory channel which merges with aerodynamic contours with a flow gap. The flow gap is of such configuration that it is closed when, and as long as, a higher pressure is exerted on the forward frontal face of the lower flange than prevails in the annular channel.The flanges are so shaped in the regions of their sealing faces that the contact pressure exerted on them increases proportionally with the pressure exerted on one of the frontal faces.

Abstract: A mixing device for viscous ingredients having a motor-driven rotor with a hollow interior defining a surface which is inclined to the axis of rotation of the rotor. Ducts coaxial with the rotational axis of the rotor feed the ingredients into the hollow interior of the rotor where they are premixed by impinging on one or more rods fixed in the rotor perpendicular to the axis of rotation. As the rods rotate with the rotor the premixed ingredients are thrown against the interior surface of the rotor where they flow over the surface to provide further mixing, the thoroughly mixed ingredients being thrown off the edge of the rotor in the form of droplets. Instead of using rods, a conical portion may be provided under the ducts in the hollow interior of the rotor.
