Abstract: A process for the production of a fluorinated quartz glass including the steps of generating SiO2 particles in a synthesis burner; depositing the resulting SiO2 particles into a body; and vitrifying the resulting body, wherein a fluorinating agent having a boiling point greater than or equal to ?10° C. is supplied to the synthesis burner.

Abstract: A heat exchanger for indirectly exchanging heat between a first medium and a second medium, the heat exchanger having a easing enclosing an encased area for receiving the liquid phase of the first medium and at least one plate heat exchanger arranged in the encased area for receiving the first medium and the second medium. The plate heat exchanger is surrounded by the liquid phase of the first medium during operation. A collecting channel is located in the encased area in order to allow for discharge of part of the liquid phase of the first medium from the encased area.

Abstract: A heat exchanger having a casing defining an encased area and at least one plate heat exchanger arranged in the encased area for indirectly exchanging heat between a first medium and a second medium. The plate heat exchanger can be surrounded by a liquid phase of the first medium. A distribution device or distributor channel is arranged above the plate heat exchanger to introduce the first medium to the encased area. The distribution device has at least one outlet opening oriented downwards through which the liquid first medium is introduced to the encased area. A conducting device is arranged below the distribution device and conducts the liquid first medium exiting the at least one outlet opening.

Abstract: An apparatus for the treatment of infections associated with respiratory disorders in a mammal with a mixture for use as an inhalable medicament. The apparatus includes a patient interface, at least one source of helium for providing gaseous helium, at least one source of oxygen for providing gaseous oxygen, an application device for providing a mixture to the patient interface, at least one source of nitric oxide for providing gaseous nitric oxide, a gas injector for injecting the nitric oxide into the mixture, an injector for injecting a means for inhibiting growth of pulmonary pathogens, a controller programmed for controlling the gas injector, the application device and the injector.

Abstract: A wheel suspension for a vehicle with a supporting vehicle element includes at least one pair of single-sided swing arms. Each single-sided swing arm is associated with a hydraulic cylinder, which is linked to the single-sided swing arm and/or the supporting vehicle element. Each hydraulic cylinder is subdivided in a fluid-tight manner into two chambers.

Abstract: The invention relates to a heat exchanger (1) for indirect heat transfer between a first medium (F1) and a second medium (F2), comprising: a shell (2) which has a shell space (3) for receiving the first medium (F1), a heat transfer block (4) which is disposed in the shell space (3) and which during correct operation is surrounded by the first medium (F1), wherein the heat transfer block (4) is designed to cool the second medium (F2) against the first medium (F1), such that a gaseous phase of the first medium (G1) forms in the shell space (3). According to the invention a collecting channel (5) located in the shell space (3) is provided for drawing off the gaseous phase of the first medium (G1) from the shell space (3).

Abstract: A triaxial constructed needle probe for reliable differentiation of multiphase media, comprises a probe body having a central light conductor having a metallic surface and a distal end of which is to be inserted in the medium, a first electrically insulating sheath disposed around the optical fiber, a hollow cylindrical shield electrode arranged around the first insulating sheath, a second electrically insulating sheath arranged around the shield electrode, and a hollow cylindrical reference electrode arranged around the second insulating sheath, as well as a measuring circuit for measuring the optical refractive index and electrical conductivity of the medium.
