The invention relates to a Method of generating oxygen and nitric oxide. The method comprises the steps of: guiding an oxygen comprising gas to a primary side of a dense membrane (42), heating the membrane (42) to a temperature at which it is permeable for oxygen, creating a pressure difference between the primary side of the membrane (42) and a secondary side of the membrane (42), wherein a stream of oxygen is generated at the secondary side of the membrane (42) and a stream of oxygen depleted gas is generated at the primary side of the membrane (42). The method according to the invention further comprises the steps of: providing a flow of nitrous oxide comprising gas and heating the nitrous oxide comprising gas to a temperature at which nitric oxide is generated. Thereby, according to the invention, heat generated in the process of operating the membrane is used. According to the invention it is possible to generate both oxygen and nitric oxide in one device making use of several synergistic effects, thus being energy saving.

The invention relates to a mercury-free molecular discharge lamp (30), which comprises: a light-transmitting discharge vessel (32) enclosing, in a gastight manner, a discharge space comprising a gas filling (34). The mercury-free molecular discharge lamp further comprises discharge means (36) for maintaining a discharge (38) in the discharge space, and discharge-variation means (40, 42) for varying, in operation, a position of the discharge within the gas filling relative to each other, and/or for varying a dimension of the discharge within the gas filling over time. An effect of the varying of the position and/or dimension of the discharge over time is that at a specific variation-speed or variation-frequency the output power and/or luminous flux of the mercury-free molecular discharge lamp is substantially increased. This effect is found to be depending on the gas filling and on the variation-speed and/or variation-frequency.

The invention relates to a method of generating oxygen. The method comprises the steps of: intermittently guiding a stream of oxygen comprising gas through at least one adsorption chamber (12) being equipped with an oxygen separation adsorbent (16), thereby defining an adsorption mode and a desorption mode of the at least one adsorption chamber (12), and thereby enriching the oxygen comprising gas with respect to oxygen, guiding the enriched oxygen comprising gas to a primary side of a dense membrane (52), heating the dense membrane(52) to a temperature at which it is permeable for oxygen, generating an oxygen flow through the dense membrane (52) to its secondary side, thereby separating the oxygen from the enriched oxygen comprising gas and forming a stream of oxygen. According to the invention, the invention further comprises the step of guiding at least a part of the generated oxygen through the at least one adsorption chamber (12) being in desorption mode. The method according to the invention allows generating oxygen in a high purity, thereby being energy saving, cost saving and being performable in a compact device.

The invention relates to a high-pressure discharge lamp with a discharge vessel having a filling comprising—a rare gas, for example argon, —mercury, and —chlorine, wherein the filling quantities of mercury [Hg] and chlorine [Cl] comply with the following conditions: —[Hg](E[Cl]3 200 (μmole/cm3)2, —[Cl] £ 10 μmole/cm3. The condition [Hg](E[Cl]3 200 (μmole/cm3)2 achieves HgCl vapor pressures in the discharge sufficient for generating significant radiation components of the B2S+-X2S+ band system of this molecule. The condition [Cl] £ 10 μmole/cm3 serves to limit the chemical aggressiveness of the chlorine filling, in particular to limit the attacks on the wall and electrodes and thus to achieve longer lamp lives. The addition of chlorine-binding metals, in particular of germanium, leads to a further improvement in the radiation and life properties of the lamp.
