Abstract:
A method for manufacturing an electrochemical cell first includes providing a cup-shaped housing with at least one first indentation. Thereafter, an electrode stack is placed in the housing and then, the first indentation is indented further in a direction towards the inside of the housing by a applying a force on the housing laterally to the first indentation, during which the electrode stack becomes fixed in the housing. As a result, electrode stacks can be fixed particularly easily and reliably in cup-shaped housings. An electrochemical cell is also provided.
Abstract:
An electrolytic capacitor in an axial type of construction with a high oscillation load factor has connection strips respectively clamped between the winding and a cup base, or the winding and a disk, and wherein the cup base and a flanged seam of a wall of the cup are respectively welded to respective connecting plates.
Abstract:
A cooling system for an electrical wound electrolyte capacitor wherein the capacitor winding 4 is mounted in a metallic cylindrical-shape housing 5 and the winding 4 has electric foils 7 and 9 which project from both ends with one of the foils being in thermic contact with the floor of the housing 6 and the other foil 9 being in thermal contact with a metallic plate 16. The heat bridges thus formed by faster and greater heat removal for high alternating currents because the temperature within the capacitor is reduced by the two separate bridges.
Abstract:
An aluminum electrolyte capacitor is provided composed of two aluminum foils between which spacers saturated with the operating electrolyte are arranged. Terminal elements are riveted and/or welded to the foils. The anode foil provided with the dielectrically acting oxide layer may potentially be produced from a larger, formed foil web. The non-formed cut edges of the aluminum foil as well as the terminal elements are covered with a fine-grained, electrolyte-compatible material. As a result thereof, the maximum operating voltage U.sub.max of traditional operating electrolytes is boosted.
Abstract:
An FTIR (Fourier transformation infrared) spectrometer is disclosed, wherein a validation/calibration of the spectrometer can be carried out in cyclically recurring intervals. Using at least two temporarily available gases, a reference spectrum with a zero gas and an absorption spectrum with a calibration gas are recorded. Substitute gases can be used during validation of the spectrometer as gas components, the substitute gases simulating actual measured gas components with respect to metrological properties.
Abstract:
A fastening arrangement uses a fastening plate for fastening a component on a printed circuit board. The fastening plate has incisions that separate the direct connections between the printed circuit board fastening points and the component fastening points of the fastening plate. Over and above this, the invention is directed to the employment of the fastening plate. Due to the incisions in the fastening plate, a solder star electrolytic capacitor having high resistance to oscillation is obtained and can be advantageously utilized in the automotive sector.
Abstract:
The invention is directed to a layer stack for the acceptance of a liquid having a suction layer (1) with high absorbency sufficing for sucking up the liquid from the edge of the layer stack into its middle and having a first storage layer (2) with low absorbency that is not sufficient for sucking up the liquid from the edge of the layer stack up to its middle between which an intermediate layer (3) composed of non-absorbent material and adjoining the first storage layer (3) is arranged, whereby a non-absorbent edge layer (7) is arranged at that side of the first storage layer (2) facing away from the intermediate layer (3), and whereby the intermediate layer (3) comprises through holes (4) whose plurality, size and distribution is selected such that some of the liquid suctioned up by the suction layer (1) can proceed via the holes (4) to the first storage layer and thoroughly saturate this. By foregoing a second suction layer, electrolytic capacitors with a significantly lower space requirement can be manufactured.
Abstract:
An aluminum electrolyte capacitor is composed of a capacitor winding, of an anode foil provided with a dielectrically effective barrier layer, having spacers (1), particularly of paper, saturated with an operating electrolyte, and of a cathode foil, and is built into a housing. The spacers have an impressed line structure (2) that is arranged from one face end of the capacitor winding to the opposite end face.
Abstract:
An aluminum electrolyte capacitor with reduced inductivity is installed in a metal housing that is closed by a cover disk provided with metallic lead-throughs. Electrically conductive bodies are arranged at the cover disk at a region of high magnetic fields when current flows.
Abstract:
A low-inductance electrolytic capacitor has an additional current guidance being provided from the winding via the pot and an electrically conductive disk to the negative lead-through, so that the current is divided for reducing the self-inductance.
