A copper-encased flat electrolytic capacitor is produced by sealing the capacitor unit in a heat-sealable polymer-copper laminate. The polymer side of the laminate is adjacent the capacitor section, and the copper side forms the exterior of the sealed unit. Leads may be attached to opposite surfaces of the capacitor, or electrical connection may be made prior to sealing, e. g. , to leg-like extensions of the laminate that, after sealing, serve as the leads.

An aluminum electrolytic capacitor has a wound extended-foil section with the edges of one of the foils extending from one edge of the roll and the edges of the other from the other edge. These extended foils are deformed after the section is wound in such a way that they are stretched and a metallurgical bond is formed between adjacent edges. A low-inductance, low electrical series resistance (ESR) capacitor is obtained as a result. The deformation may be accomplished by frictional cutting using a diamond saw.

A solderable metal layer is chemically deposited as an electrical contact on a solid-electrolyte capacitor by replacing the conventional silver contact layer of the capacitor with a layer of colloidal carbon containing a metal which is more electropositive than the solderable metal to be deposited, and thereafter contacting the assembly with a salt solution of the solderable metal. The metal of the salt solution is chemically replaced by the more electropositive metal so that the solderable metal plates out on the carbon surface to form the desired solderable contact layer. The salt solution is preferably a copper or nickel salt solution, and the more electropositive metal is preferably iron.

A wound and flattened extended-foil section containing an electrolyte is encased within a frame of insulating material that is closed on the top and bottom by metallic members electrically insulated and spaced from each other by the frame. One electrode of the section is electrically connected within the frame to one of the metallic members, and the other electrode is electrically connected within the frame to the second metallic member. The metallic members may serve as terminals for the capacitor, or leads may be attached to their external surfaces.

A compact and economical supplemental home heating system utilizes a colloidal suspension of finely divided graphite particles as the collection medium. The emitter of the system is closely spaced from the collector so as to reduce complexity and cost of the system itself, as well as to facilitate inexpensive installation into existing dwellings.

A flat electrolytic capacitor section is provided with a vapor barrier by sealing the section in an insulating, heat-sealable polyester, polyolefin, perflouroethylene, or cellophane film.
