Abstract: A valve metal powder by is prepared by a particular set of sequential steps that involves the use of precursor having preformed morphology. The method by which the valve metal is prepared includes a stabilization step that results in the valve metal powder having secondary and tertiary structures that each corresponds to the secondary and tertiary structures of the precursor. Also described is a method of producing solid electrolyte capacitors that include the valve metal powder of the present invention.

Abstract: Process for producing a valve metal powder by producing a precursor of desired morphology, converting the precursor into an oxide of the valve metal, stabilizing the structure of the oxide by heat treatment and reducing the stabilized oxide while retaining the morphology. Valve metal powders obtainable in this way, in particular comprising spherical agglomerates with a mean agglomerate size of 10-80 &mgr;m, preferably 20-40 &mgr;m, and use of these valve metal powders to produce solid electrolyte capacitors.

Abstract: A battery-operated implantable medical device comprises a battery, a measuring device for determining the state of charge of the battery through measurement of the no-load voltage, and an electric load. The no-load voltage of the battery has an increased drop in a range in which a remaining residual energy suffices to keep the operation of the device going for a minimum period of time required to carry out a therapeutic process.

Abstract: A sealed galvanic cell which has high power and energy densities, a low self discharge, and an open circuit voltage which is related to state of discharge, and which is useful for supplying electrical power to an implantable device, such as a defibrillator and a nerve stimulator, with a large current consumption, and method of making same. The galvanic cell includes a casing; a cathode unit having at least one electrode composed of a mixture of at least one metal oxide and at least one lead compound; an anode unit having at least one electrode comprised of an alkali metal; and an organic electrolyte comprised of a mixture of (a) ethylene- and/or propylene carbonate, (b), 2-dimethoxyethane, and (c) a conducting salt. The mixture of the cathode unit is one of (a) a mixture of CrO.sub.x (x=2.5 to 2.7) and at least one lead compound from among PbCrO.sub.4, PbMoO.sub.4 and PbO, (b) a mixture of CrO.sub.x (x=2.5 to 2.7), MnO.sub.2, and at least one lead compound from among PbCrO.sub.4, PbMoO.sub.

Abstract: Pharmaceutical preparation in tablet form for supplying fluoride ions for the treatment and prevention of losses of bone substance, including osteoporosis and alveolar bond damage, with a content of sodium fluorophosphate and substances for regulating the release of sodium fluorophosphate, the substances for the regulation of the sodium fluorophosphate release comprising a dual retardant system which consists of a retardant matrix in the tablet core and a retardant coating.

Abstract: The invention relates to an improvement of the flowability and an increase in the bulk density of high-surface area valve metal powders by means of the addition of finely divided extraneous metal oxides in quantities of up to 5000 ppm, relative to the quantity of metal, before the powder-metallurgical processing of the valve metal powder.

Abstract: The invention relates to a process for treating the surface of valve metals, in particular niobium and tantalum, in the form of agglomerated or non-agglomerated powders, thin foils or molded articles prepared from powder, for use as electrolytic capacitor electrodes, these metals being heated in at least one stage to temperatures of 300.degree. to 2,000.degree. C. under a high vacuum or an inert gas atmosphere and in the presence of chalcogens or chalcogen compounds, excluding oxygen.

Abstract: To produce valve-metal anodes for electrolytic capacitors, reducing agents are added to the already sintered and/or unsintered anode bodies to improve the electrical properties, whereupon heating is carried out at temperatures above the melting point of the reducing agents and below the temperatures conventionally used for sintering the valve-metal anodes.
