Abstract: An electrical capacitor is formed utilizing a thin dielectric layer which is metallized on both sides to provide electrode areas. Unmetallized margin areas are provided on one side of the dielectric layer along the longitudinal edges of the layer, an unmetallized strip is provided in the center of the other side of the dielectric area which extends along the longitudinal dimension of the layer. The capacitor is formed by pleating, or folding, the dielectric layer along its longitudinal dimension an odd number of times, but with at least five pleat lines being formed and with one of the pleat lines being along the center of the dielectric layer so that the unmetallized strip is on the inside of the center pleat. The center pleat extends beyond the ends of the other pleats on one longitudinal edge of the capacitor while the ends of the metallized dielectric layer which contain the unmetallized margin areas extend beyond the ends of the pleats on the other longitudinal edge of the capacitor.

Abstract: A machine which may be used to either check or to machine the profile of an orbiting star gear for a gerotor type of fluid motor or pump is disclosed. The profile of a star gear is traced due to the interaction of a slide that carries a sensor, or a machining tool, in a back and forth direction toward and away from the star gear and in a second direction transverse to this back and forth direction with respect to a frame member. The slide is driven by an eccentric disc, at a rate which is determined in accordance with the number of teeth on the specific star gear in question. The combined motion of the star gear and the two slides causes the sensor, or the machining tool, to trace out the profile of the desired star gear for the purpose of either checking its profile, or of machining a new gear. A spring member is connected to the frame member to allow the frame member to move in a transverse direction but without rotation.
