Abstract: A getter assembly is described which has an improved support such that the points of contact with the glass wall of a cathode ray tube have as low a temperature as possible.A tab member for mounting the getter device is attached to the lower side of a central disc shaped zone of the getter device formed of an upraised bottom portion of the bottom wall of the ring getter. Said tab member extends without touching the inner side wall of the getter material container of its bottom wall. A support means is attached, for example by spot welding, to the tab member, and has at least two concave surfaces facing the bottom wall of the container and lying in a plane perpendicular to the outwardly extending zone of the tab member. The support means can be attached to the tab in the same area as which the tab is attached to the central zone of the upraised bottom portion of the container.

Abstract: Life expectancy, through reduction of filament sag and halogen corrosion of tungsten filaments, is greatly increased for tungsten-halogen lamps by including within the filament environment a quantity of copper. The copper can be present as one of the lead-in wires; a plating on the lead-in wires; a separate copper insert; or a coating on the filament. It is believed the copper acts as an oxygen getter.

Abstract: A tungsten-halogen incandescent lamp has a hermetically sealed light-transmitting envelope with a fill of inert gas and halogen, a tungsten filament and a preferential tungsten deposition site of palladium material within the envelope.

Abstract: A tungsten-halogen lamp employs a slidable getter which automatically positions itself in the lowest, and thus, coolest, portion of the envelope where it is most efficient. This feature allows such lamps to be burned in a horizontal or vertical mode; the vertical mode including both base down and base up positioning.

Abstract: A single-ended tungsten halogen lamp having a tubular hardglass evenelope containing an inert gas and a halogen, preferably bromine. An improved halogen regenerative cycle in this type of lamp is achieved by minimizing the bromine and impurity attack on the tungsten filament, thus increasing lamp life over a wider application temperature range, through the use of a tantalum or zirconium getter which is in the form of a coil. This coil is particularly useful in small volume lamps, and in a preferred embodiment, is attached to the filament mounting structure (bridge) on the side thereof opposite the main filament body.

Abstract: An oxidation-sensitive element electrically connected in series with the discharge vessel of a high-pressure discharge lamp extinguishes the lamp when the element, upon fracture of the outer envelope of the lamp, is oxidized and prevents damage as a result of emission of UV radiation.In a high-pressure discharge lamp according to the invention, the oxidation-sensitive element (7) consists of an electric insulator (20) on which two spaced conductors (21, 22) are provided which are interconnected electrically by a vapor-deposited layer (23) of an oxygen-gettering metallic, evaporating getter. Opposite to the insulator (20) is present a holder (8) from which the getter was previously evaporated on to the insulator.
