  • Low-pressure mercury-vapor discharge lamp
    Patent number: 6646365
    Abstract: A low-pressure mercury-vapor discharge lamp has a discharge vessel with a filling of mercury and an inert gas. Electrodes in the discharge space have electrode shields, which operate at temperatures above 450° C. An inner surface of the electrode shield may have a heat-absorbing coating, for example a carbon film. The electrode shield may be supported by a support wire, at least a part of which is made from stainless steel. A lamp according to the invention has comparatively low mercury consumption.

  • Low-pressure mercury vapor discharge lamp
    Patent number: 6417614
    Abstract: A low-pressure mercury vapor discharge lamp comprises a discharge vessel (10) having a tubular portion (11). The discharge vessel (10) encloses a discharge space (13) provided with a filling of mercury and a rare gas in a gastight manner. The tubular portion (13) of the discharge vessel (10) is provided with a metal oxide layer (15) and a luminescent layer (17) on a surface (14) facing the discharge space (13). The discharge lamp comprises means for maintaining an electric discharge in the discharge vessel (20b). The discharge lamp is characterized in that the luminescent layer (17) comprises an alkali metal oxide. This alkali metal oxide is preferably sodium oxide and/or potassium oxide, and the concentration of the alkali metal oxide is 0.002≦Na2O≦0.1% by weight and/or 0.002≦K2O ≦0.1% by weight. The tubular portion (11) of the discharge vessel (10) preferably has a further metal oxide layer which acts as an alkali metal-repellent layer.

  • Stabilized polyesters and polyester urethanes containing an aromatic carbodiimide and a quinone
    Patent number: 5130360
    Abstract: Polyesters and polyester urethanes are stabilized against discoloration and hydrolytic degradation by inclusion therein of an aromatic carbodiimide and either a benzohydroquinone or a naphthohydroquinone compound, and at the same time, the quantity of isocyanate eliminated from polyester urethanes is considerably reduced.
