Abstract: An ophthalmoscopic attachment 1 for a surgical microscope 13 accommodates an optical system 14 which erects an inter-image of the fundus (or other particular area of the vitreous body of the eye) produced by at least one ophthalmoscopic lens 8 and interchanges the optical viewing paths. The optical system 14 is located directly behind the produced inter-image at a point where the stereoscopic optical viewing paths are still intertwined. The optical system 14 is configured either as a triplet with field lenses or as a straight-view inversion prism. The attachment also includes a lens 15 that is (a) positioned between the optical system 14 and the lens end of the attachment, and (b) movable along the optical axis of the attachment to put the critical section of the eye into focus.

Abstract: A microscope having two optomechanically coupled observation barrels to permit simultaneous use by two individuals. While each barrel is provided with its own eyepieces and its own magnification system, they share a common optical axis including a single objective lens and a specially designed composite prism which allows part of the observation beam (the light reflected by the object) to pass through it, undiminished, to one of the observation barrels, while the other part of this light is deflected to the other observation barrel by a mirror layer within the prism. The microscope's illumination beam is directed onto the object field along the same common optical axis followed by the returning observation beam, and this illumination is deflected into this optical axis at a point between the object field and the objective lens.

Abstract: SO.sub.2 -containing, hot gases are catalytically converted in part in a first contacting stage. The water and the SO.sub.3 formed is removed from the reaction gas. The remaining gas is heated and then supplied to the second contacting stage. The water vapor content in the reaction gas delivered by a first contacting stage corresponds to an H.sub.2 O/SO.sub.3 mole ratio below 1. The reaction gas delivered by the first contacting stage is precooled by an indirect heat exchange to such a temperature that the wall temperatures of the heat exchanger are above the dew point temperature of the reaction gas. The precooled reaction gas entering a condensing stage is contacted in a venturi with cocurrent sulfuric acid of 98.0 to 100% concentration and a temperature of at least 95.degree. C. The exit temperature of the gas from the condensing stage is maintained at least at 120.degree. C. The gas rises in a succeeding absorption stage through a packing layer, which is contacted with trickling sulfuric acid having a concentration of 98 to 100% and a temperature of 70.degree. to 120.degree. C. The dry gas which leaves the absorption stage and has been freed from SO.sub.3 is maintained at a temperature which is as high as or slightly higher than the temperature of the acid as it initially contacts the packing in the absorption stage. The sulfuric acid concentration is controlled by a supply of water into the sulfuric acid in the condensing and/or absorption stage.
