摘要： The invention relates to a method and an apparatus for reconstructing a three-dimensional image volume from two-dimensional projection images of a subject which have been taken from different projection directions by rotating the recording system around the subject, wherein the grayscale values of the voxels of the image volume are calculated by back projection of the projection images. The invention is characterized in that prior to back projection at least one projection image is modified in such a way that it corresponds to a projection image taken with a virtual detector whose axes are aligned parallel to the rotational axis of the recording system.

摘要： A calendar date display comprises a ten-day indicator (2) and a unit indicator (1) driven by a program drive (8), which is provided with a calendar date display (9) whose toothing is engaged with the beak (15) of a lever (16) in such a way that a wheel is moved one step forward by one date number change. Between each calendar number change, the beak (15) is engaged between the first and second teeth (11, 12) of the wheel (9). At the time of the calendar number change, the beak (15) is disengaged from said first and second teeth (11, 12) in such a way that it is engaged between the second and third (12, 13) teeth of the wheel (9), thereby moving said wheel one step forward.

摘要： The invention relates to a process for the separation of condensable and absorbable gas components having a critical temperature above 30.degree. C. from a mixture with inert gases, being absorbable at most in a little measure and the proportions of the components of said mixture varying widely, by two-stage absorption and simultaneous compression of the cleaned gas and the separated components to different pressures, in which the varying composition of the gas mixture to be separated is equalized in a first absorption stage so that at least temporarily part of the absorbable components of the mixture is absorbed. The remaining gas mixture is compressed and then introduced into a second absorption stage, wherein are obtained an inert gas mixture largely free from absorbable components and a solution rich in absorbable components, from which the absorbable components of the gas mixture are separated through subsequent multi-stage thermal desorption, the absorbent being fed back into the process.
