A xenon arc lamp for a motion picture projector is cooled by providing the anode end of the lamp with a shroud that forms part of a support for that end of the lamp. Cooling air flows into the shroud along the support arm and enters the shroud through a slot in its side wall. The shroud provides an annular air space around the anode end of the lamp and has an annular air outlet through which the cooling air leaves as a "sheet" of laminar air flow which tends to adhere to the surface of the bulb, thereby providing precise cooling. In this way, arc instability is avoided or minimized, while lamp life is extended.

A method and apparatus for forming controlled stress fractures in metal produces electrically isolated, closely spaced circuit sub-entities for use on a metallized printed wiring board. A polymeric substrate has a layer of metal adhered to the surface, and the metal layer is formed into entities. Each entity has a fracture initiating feature formed into it, which serves to initiate and/or direct a stress crack that is induced in the metal. The entities are fractured in a controlled manner by subjecting the substrate and the entities to mechanical stress by a rapid thermal excursion, creating a stress fracture in the entity extending from the fracture initiating feature. The stress fracture divides each entity into two or more sub-entities that are electrically isolated from each other by the stress fracture. The resulting structure can be used to form circuitry requiring very fine spaces for high density printed circuit boards. The rapid thermal stress may be induced by a high intensity, strobed xenon arc lamp.
