Abstract: Electrode foils suitable for use in electrolytic capacitors, including those having multiple configurations, have improved strength, reduced brittleness, and increased capacitance compared to conventional anode foils for electrolytic capacitors. Exemplary methods of manufacturing an anode foil suitable for use in an electrolytic capacitor include forming a pattern of etch resist on a surface of a substrate; etching a first area of the surface substantially enclosed by the pattern and a second area in intervals between the pattern to form tunnels in first and second areas of the surface; and removing the resist material revealing a non-etched frame. The resist material may be deposited, for example, by ink-jet printing, stamping or screen printing. Additionally, an etch resist pattern may be used to form strength lines on the substrate surface.

Abstract: A capacitor assembly is configured for use with an implantable medical device (IMD. The capacitor assembly may include a stack assembly having at least one anode stack between outer cathodes, and a housing having a case secured to a lid. The case and the lid define an internal chamber that retains the stack assembly. One of the case or the lid comprises a folded double wall connected to a drawn end. A recessed area is defined between the folded double wall and the drawn end. A linear edge of the other of the case and the lid is retained within the recessed area.

Abstract: A chuck for a power tool having a plurality of chuck jaws of the type that open to receive a work tool and close to grip the work tool, wherein the chuck comprises a front sleeve, a rear sleeve, and an integral chuck jaw unit fitted within the front and rear sleeves in a removable manner. The chuck jaw unit includes a plurality of chuck jaws, a support body having individual jaw bores for receiving the chuck jaws, a traveler affixed to the remote ends of the chuck jaws; and an operator for reciprocating the traveler along a chuck axis to open and close the chuck jaws. The traveler includes internal traveler threads and the operator includes a threaded barrel in the form of a jack screw on which the traveler threads up and down. The operator of the chuck unit and the rear sleeve may be press fitted together so that manual rotation of the rear sleeve causes the operator to rotate whereby the traveler reciprocates.

Abstract: For a powered hand tool having a plastic housing and requiring a slide button with a detent action for at least two positions with an audible indication of the transition from one position to another position, a plastic spring molded as part of the housing and having an arched surface extending into the path of a projection from the slide button which has first and second oppositely disposed tapered sides extending towards each other and terminating in a flat base portion which coacts with the arched surface to provide a detent action and an audible indication of the transition to a new position when the slide button impacts upon abutments formed as part of the housing.
