A device having a quartz or glass body forming a chamber hermetically sealed by one or more pinch seals formed in the body wherein a metallic foil provides an electrical connection through a pinch seal. A method is provided for protecting a portion of the metallic foil from corrosion prior to forming the pinch seal by coating at least a portion of the foil with a film comprising silica, and applying a refractory abhesive to at least a portion of the film.

Apparatus and methods for use of refractory abhesives in protection of metallic foils and leads

An electrical lead assembly for devices such as electrical lamps having a metallic foil for providing an electrically conducting path through a hermetic seal formed by pinch sealing a vitreous material. The metallic foil includes an oxidation-inhibiting coating of silica. In another aspect of the invention, methods of coating metallic foils with silica are disclosed. In yet another aspect of the present invention, an electrical lead assembly for lamps is provided wherein the metallic foil is extended to form an outer electrical lead for the lamp.

Oxidation-protected metallic foil and methods

The present disclosure provides an audible alarm system that utilizes air-conveying ductwork to transport the audible alarm signal from the point of origination to a distant location. This system is low cost and improves the safety of individuals and reduces the potential loss of property by providing early and better hazard communication.

Oxidation-protected metallic foil and method

The present invention includes barrier coatings and methods for reducing or preventing chemical reaction between the discharge medium and arc tube wall material in discharge lamps. The barrier coatings comprise nitride layer exposed to the discharge medium formed from one or more of aluminum, boron, scandium, yttrium, or the lanthanides. In another aspect, the present invention includes methods of forming coatings on the inner wall of arc tubes by introducing two or more precursors into the arc tube chamber and pyrolitically reacting the precursors to form layers for the coating.

This invention relates to a lighting system for a rotating object wherein the lights are made to appear stationary by being turned on and off in synchrony with the rotation of the object. This synchronization is achieved by utilizing magnetic field sensors which determine the instantaneous orientation of the object relative to the Earth's magnetic field.

Lighting system for rotating object

The invention relates to a system and method for monitoring light using a photosensitive mast mounted on a support or machine. A light signal, such as a laser, is detected by the photosensitive mast which has a plurality of optical fibers distributed longitudinally along and completely around the mast. The optical fibers are of lengths which differ by very small amounts, thereby creating any desired resolution of the photosensitive mast. The optical fibers are connected to a collecting device for gathering the light signals and determining the position of the light measuring device relative to the rotating laser light source.
