A mold is provided having a porous metal insert through which a mold release agent can be pumped to provide a desired, precisely metered quantity or coating of the release agent at a desired location along the inner surface of a mold cavity, or at the inner surface of an injection port, between or at periodic intervals of successive moldings of parts. The need to manually apply mold release agent between successive moldings, for example to the injection port of an injection mold, is reduced, thereby reducing or substantially eliminating inconsistent applications of release agent that are characteristic of manually applied coatings. A method of molding using the disclosed porous metal insert also is provided.

An arc tube for a ceramic metal halide lamp includes a hollow first body member () that is tapered along a majority of its length to aid in removing the molded component from a pin during assembly. An open end () of the first body member has a constant diameter () allowing it to be joined to a constant diameter portion () of the second body member or end cap (). The mating constant diameter portions ensure that the hollow first body member can be monolithically joined with the end cap with a reduced level of seal voids.

A discharge chamber for a lamp, the discharge chamber comprising a monolithic ceramic article having a main body defining an arc chamber and generally opposed leg members defining openings which may accommodate an electrode or electrode lead through. A method of making a ceramic discharge chamber comprising the steps of forming a mixture comprised of ceramic powder and a binder and injecting the mixture into a die and around a mold to form at least a main body of the discharge chamber.

A lamp is provided with a mounting arrangement for achieving a precise alignment. The lamp includes a double-ended light source, a metal strap clamping one end of the light source at two locations, and a plastic base having an internal opening wherein the metal strap is engaged. The metal strap includes two clamping members between which the light source is clamped and a cap member attached to the clamping members. The cap member has tabs adapted for engaging the internal opening of the plastic base and gimbaling the light source to align the light source with respect to the plastic base. The clamping members are joined together at a point between the to clamping locations such that a spring force clamps the light source. The clamping members are also oriented at an angle of about 45 degrees from vertical to better withstand both vertical and horizontal loads.

Metal strap for holding cylindrical lamp

A replaceable lamp assembly for automotive headlamps includes an incandescent lamp having a pinch seal mounted on a plastic base by means of a one piece sheet metal holder. One end of the holder clamps around the pinch seal of the lamp and the other end is secured to the plastic base via a pair of leg portions each having a spherical gimballed end RF welded to the base.

Replaceable lamp assembly for automotive headlamps

A mount for a minature lamp terminating at one end in an elongated tubular member, said mount comprising a base and a cap assembled in mating engagement and exerting a compressive force on at least one deformable, elastomeric tubular or ring shaped member in said mount which surrounds and contacts said tubular lamp member of which at least a portion of which is inserted in a bore in the mount, thereby holding the lamp in the mount.

Mount for miniature arc lamp

A circular fluorescent lamp unit having a central screw-in hub containing lamp ballast means, and a plurality of support arms extending from the hub and having curved outer ends to support a circular lamp. The support arms are metal or plastic strips which enter through slots of the hub and are bent at substantially right angles within the hub so as to be held in place while having limited radial movement with respect to the hub to enable them to accommodate and support circular lamp bulbs of varying dimensions such as due to manufacturing tolerance variations.
