摘要： The invention is directed to a method of producing coarse-crystalline nicotinic acid with a high degree of purity in which 3-cyanopyridine is saponified with aqueous alkali hydroxide and the nicotinic acid is allowed to crystallize out of the alkali nicotinate solution obtained in this manner under the addition of mineral acid at temperatures between 99.degree. and 135.degree. C. The pH is kept above 3.7.

摘要： A luminescent storage screen of the type used to latently store an x-ray image in an x-ray diagnostics installation has two phosphor layers separated by and carried on a carrier disposed therebetween. The carrier is substantially transparent to x-radiation, so that the x-ray image is stored in both phosphor layers. A read-out apparatus for the storage screen includes a read-out beam generator which generates a single read-out beam which is directed at one side of the storage screen. The carrier is transmissive to the read-out beam, but is impermeable to light emitted by the phosphor layers, so that the light emitted by each phosphor layer during simultaneous read-out can be separately collected and detected. The single read-out beam simultaneously scans both phosphor layers, so that the resulting images are automatically correlated. The images are then combined in a known manner to form a single, displayed image.
摘要翻译：用于在x射线诊断装置中潜藏X射线图像的类型的发光存储屏幕具有由设置在它们之间的载体上分离并承载的两个荧光体层。载体对x辐射基本上是透明的，因此x射线图像被存储在两个荧光层中。用于存储屏幕的读出装置包括读出光束发生器，其生成指向存储屏幕的一侧的单个读出光束。载体对于读出的光束是透射的，但是对于由荧光体层发出的光是不可渗透的，使得在同时读出期间由每个荧光体层发射的光可以被单独收集和检测。单个读出光束同时扫描两个荧光体层，使得所得到的图像自动相关。然后以已知的方式组合图像以形成单个显示的图像。
