Abstract: The metal halide lamp with a ceramic discharge vessel (4) has sealing means at its two ends (6), an electrically conductive lead-through (9, 10; 30) being guided through these means in a vacuum-tight manner, to which lead-through an electrode (14) with a shank (15) is attached, which electrode projects into the interior of the discharge vessel. At least a front part, which faces toward the discharge, is designed as a component made from electrically conductive cermet which comprises a halide-resistant metallic phase and a ceramic phase of a ceramic base material. The fill comprises at least one halide of a rare-earth metal. At least on the front side of the component, at least part of the ceramic phase comprises the combination of the ceramic base material and one or more rare-earth metal oxides.

Abstract: Each electrode comprises a shaft (6) and a head (5), the shaft being sealed in a vacuum-tight fashion in each case in an end region (2, 22) of the discharge vessel. At least one electrode is cooled by virtue of the fact that its shaft contains a cooling tube system in which a coolant (11) circulates. Said cooling tube system is surrounded at a spacing by an additional enveloping tube (9, 16), the interspace (10, 20) between the enveloping tube and cooling tube system being fitted with a means of thermal insulation.

Abstract: Lighting system, comprising a mercury-free metal halide lamp with a light yield of at least 75 lm/W and a color rendition index of at least 75 and an electronic ballast, the electronic ballast impressing a square-wave power supply on the lamp and keeping the power constant. The filling comprises the following components:a buffer gas which also acts as starting gas to start the lamp,a voltage gradient generator, comprising at least one metal halide which vaporizes readily and which is chiefly (by more than 50%) responsible for generating a voltage gradient which corresponds approximately to that of mercury, anda light generator comprising one metal and/or one metal halide.

Abstract: A cable connector assembly is provided which is particularly useful as a vehicle antenna cable connector. Two mating connectors are provided, one having a male contact and the other having a female contact. A pair of latches is provided which engage one another when the contacts are fully electrically connected. A resilient member is contained in one of the connectors to urge the connectors apart if the connectors are not fully connected and the latches fully engaged.

Abstract: The invention concerns high-pressure discharge lamps, whose electrodes have a sintered compact (5) containing lanthanum oxide acting as an electron emitter, and this compact is surrounded by an electrode coil (6). Sintered compact (5) contains at least 90 weight % lanthanum oxide. In this way, a high thermal stability of sintered compact (5) and a good ignition performance of the lamp are assured with only negligible blackening of the discharge vessel over the service life of the lamp.

Abstract: A contact assembly for electrically conductively engaging large numbers of electrical connections between printed circuit boards. A plurality of pins mounted on one board are mated to a plurality of corresponding contacts mounted on another board, such contacts being contained in cavities extending along respective axes in a housing such that when the pins are fully engaged by the corresponding contacts each contact is substantially concentric relative to a corresponding axis and pin, and when the pins are not fully engaged by the corresponding contacts each contact extends at an angle relative to a corresponding axis.

Abstract: A simple photoionization technique for enriching a particular isotope of mercury in a naturally-occurring mixture employing an isotopically pure radiation source separately optimized for 253.7 nm. and 404.7 nm. emission, respectively. A vessel is provided for containing the naturally occurring mercury. This vessel may be part of either a flow or closed system. The radiation source brings the isotope from the 6.sup.1 S.sub.0 ground state to the 6.sup.3 P.sub.1 state wherein the nitrogen gas deactivates the isotope to bring the isotope to the long-lived 6.sup.3 P.sub.0 state. Thereafter, the source optimized at 404.7 nm. brings the isotope to the 7.sup.3 S.sub.1 state. At this level the atom may be easily photoionized either by a laser or a powerful visible incoherent radiation source.

The base substrate has typically deposited thereon multiple thin film layers. The hermetic seal comprises an electrically insulative thin film layer disposed over the conductive thin film leads associated with the multiple thin film layers, and metallic solder means over the insulative thin film layer to provide a bond between the cover sheet and base substrate.
