    Abstract: Photopolymer printing plates having, on top of a photosensitive layer (a) attached to a base, a thin layer (b) of a suspension of finely crystalline conjugated diacetylene compounds in a binder, which compounds change color when photopolymerized. Such printing plates make possible the production of positive copies of a positive transparency by producing in layer (b) an image with areas which do not transmit light by exposure to light having a wavelength of less than 320 m Mu and optional fixing, and initiating photopolymerization in layer (a) by exposing it through the said image to light having a wavelength of from 320 to 450 m Mu and then washing out the unexposed areas of layer (a).

    Abstract translation: 光敏聚合物印版在其上粘附有感光层（a）的顶部，在粘合剂中具有微细结晶的共轭二乙炔化合物的悬浮液的薄层（b），该化合物在光聚合时变色。 这样的印版通过在层（b）中产生具有通过暴露于波长小于320μm的光而不透光的区域的图像（任选地固定）并且引发​​光聚合来生成正透明度的正拷贝 在层（a）中通过将其穿过所述图像曝光到具有320至450μm的波长的光，然后冲洗出层（a）的未曝光区域。

    Abstract: THE INVENTION RELATES TO A METHOD OF MIXING A GAS WITH LIQUIDS IN A TUBULAR REACTOR BY FEEDING THE GAS AND THE LIQUIDS TO A MIXING zONE. THE INVENTION ALSO RELATES TO AN SEPARATUS FOR CARRYING OUT THIS METHOD. RAPID MIXING ID EFFECTIVE BY FEEDING A STREAM OF LIQUID TO THE MIXING ZONE THROUGH ONE OR MORE NOZZELS WHOSE AXS EXTEND IN THE SAME DIRECTION AS THE AXIS OF THE MIXING ZONE, IN INJECTED LIQUID HAVING A VELOCITY OF FROM 5 TO 100 M./S., WHILST A SECOND STREAM OF LIQUID OF MUCH LOWER VELOCITY IS INTRODUCED INTO THE REACTOR INLET ZONE SURROUNDING SAID NOZZEL. THE GAS IS FED TO THE MIXING ZONE THROUGH ONE

    OR MORE GAS INLETS LOCATED NEAR THE ORIFIECES OF THE LIQUID NOZZELS. THE MEAN CROSS-SECTIONAL AREA OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE CROSS-SECTIONAL AREA OF THE ORIFICES OF THE LIQUID NOZZLES AND THE LENGTH OF THE MIXING ZONE BEARS A SPECIFIC RATIO TO THE HYDROLIC DIAMETER THEREOF. THE METHOD AND APPARATUS ARE PARTICULARLY SUITABLE FOR CARRYING OUT REACTIONS IN WHICH SHORT RESIDENCE TIMES ARE DESIRABLE AND THE REACTION PRODUCTS MUST NOT RECONTACT THE STARTING MATERIALS.
