Abstract: A first mold die and a second mold die are moved together and are shaped to define a mold cavity therebetween. A capacitor pellet is positioned within the mold cavity and a plurality of projections extend inwardly to engage the capacitor pellet and hold it spaced away from the cavity side wall.

Abstract: A capacitor includes a pellet molded within a protective material and having a cathode termination surface at one end and an anode wire extending from the other end. The cathode termination surface is centered with respect to the longitudinal axis of the capacitor. The method includes centering the pellet body and a tear drop shaped conductive cathode element within a mold and molding a protective coating around them. After the molding is complete a portion of the tear drop shaped member is removed to create a cathode termination.

Abstract: A first mold die and a second mold die are moved together and are shaped to define a mold cavity therebetween. A capacitor pellet is positioned within the mold cavity and a plurality of projections extend inwardly to engage the capacitor pellet and hold it spaced away from the cavity side wall. The method comprises placing the pellet body within the cavity molding and retentively engaging the pellet body with a plurality of projections to provide a space between the pellet body and the cavity side wall. A molding material is used to fill the space to provide a coating on the pellet body.

Abstract: A method of manufacturing a tantalum capacitor includes compacting tantalum powder about a tantalum anode rod in such manner than the tantalum powder in a region in registry with the tantalum rod is compacted to a density of from about 8 to 10 grams per cc or more, whereas the density of the remaining portions of the tantalum powder mass are compacted to a density of from about 4 to 7 grams per cc. The disclosure further relates to a improved capacitor formed in accordance with the method, as well as to an improved capacitor preform, the capacitor and preform being characterized in that a higher reliability mechanical and electrical connection is effected between the anode rod and the tantalum materials surrounding the rod.

Abstract: A downdraft woodburning stove in which there is improved combustion, heat transfer and combustion regulation comprising novel air inlet circulation, grate construction and automatic control of (1) temperature of exhaust gases and (2) of combustion air, and (3) the supplies of both primary and secondary air to a plurality of combustion areas.
