    摘要: Enterally absorbable diastereomers of 1-(isopropoxycarbonyloxy)ethyl (6R,7R)-7-[2-(2-aminothiazol-4-yl)-2-(Z)-(methoxyimino)acetamido]-3-(methoxymethyl)-3-cephem-4-carboxylate of the formula I ##STR1## and their physiologically acceptable salts and also diastereomerically pure salts of the compounds of the formula II ##STR2## where HX is a mono- or polybasic acid and where X is an inorganic or organic physiologically acceptable anion, and a process for the preparation of these compounds of the formula I or II, which comprises first precipitating the more sparingly soluble diastereomer of the formula IV in the mixing together of 1 equivalent of a solution of the diastereomer mixture of the formula III with 0.2-2 equivalents of a solution of the acid component HY and separating it off by filtration, then precipitating the more readily soluble diastereomer of the formula IV from the filtration solution, it being possible for the acid component HY to be identical or different in the consecutive partial steps and any desired sequence of addition of different acid components HY being possible, and optionally further purifying the obtained salts by crystallization, are described.

    摘要: A magnetic recording medium, consisting essentially of a polymeric, web-like substrate and a coherent thin layer of a ferromagnetic material, is produced in a chamber under reduced pressure by depositing a vapor jet of the ferromagnetic material onto the moving substrate surface guided over a cylindrical drum, by a process in which the axis of the cooling element is inclined relative to the plane of the evaporator unit.

    摘要: A seat for an automobile includes a backrest fitted with a frame, an adjusting device inside the backrest in the region of the lumbar vertebral column, an elongated, resiliently bending element running transversely inside the frame, two bowden cables each with a sheath and a traction wire, a drive device at the backrest one rest for each bowden cable sheath in each end zone off the elongated element and through which the traction wire is made to pass in longitudinally displaceable manner, an affixation of the free end of the traction wire at a part of the backrest frame facing it whereby the elongated element is suspended in such manner in the frame that, when a tension is exerted on the traction wire, the elongated element shall be moved forward.
