| (2) having indentations to effect good contact. A spring was placed at the bottom of the case to keep the connecting washers hard up against the foils. The insulation between the foils was two ply wax paper .001" thick 1 1/2" wide and the foils 1 3/8" wide, the total length unwound being 8 feet. A turn of thick insulating paper was wound round the whole condenser to insulate it from the case at the sides. The insulated terminal consisted of a screw screwed into the centre of a 3/16" diameter mandril provided with small peripheral serrations. This mandril also formed the base on which the condenser was wound. This design is certainly worthy of note as pressing the condenser flat, as is our practice, tends to cause variations of capacity after manufacture. HEWest. | ||
