Abstract: An antivibration mounting-spacer device for an electrolytic capacitor section consists of a sheet of material that can be wrapped around the rolled section and has a plurality of fingers extending outwardly from one side of the sheet away from the section. The sheet is rectangular, and its dimensions are such that the sheet extends beyond both ends of the section and encompasses at least a major portion of the circumference of said section. When the section with the sheet wrapped around it is inserted into a capacitor can or container, the fingers bend enough to allow insertion but remain urged against the inner surface thus holding the section in place and preventing its vibration.

Abstract: A process for the accelerated aging and impregnation of electrolytic capacitors having formed anodes is carried out in two stages. In the first stage, the capacitors are loaded into a centrifuge, a voltage less than final aging voltage is applied, the pressure within the centrifuge is reduced, the centrifuge is started, and then electrolyte is admitted to impregnate the capacitors. When the capacitors are fully impregnated, the aging voltage is increased to the desired final value.
