Номер: RU2280507C2

Группа изобретений относится к суперпараллельной аналитике биополимеров с применением микрополимерных полей. Способ изготовления биополимерных матриц осуществляют путем микродозирования на поверхность предметного носителя минимальных количеств жидкости с помощью аппликатора с капиллярным пространством, приводным капилляром и пипеточным кончиком. Причем в приводной капилляр подают буферный раствор из питающей емкости с возможностью перемещения кончика капилляра в трехмерном пространстве. При приложении к приводному капилляру электрического напряжения соответствующей полярности обеспечивается всасывание дозируемого биополимера или нанесение его на поверхность предметного носителя. Представлено также устройство для изготовления биополимерных матриц. Достигается простота и надежность нанесения минимальных количеств жидкости на биополимерную матрицу. 2 н. и 9 з.п. ф-лы, 1 ил.

Controlling addn. of gas or liq. to drink - by balancing double system responsive to property changes

Номер: DE0003024493A1

The property concerned is measured in the mixt. and the actual value is compared with an index value by a second control system. When a permitted deviation is exceeded, a corrective signal alters the instantaneous index value at specified intervals. The first control system supplies the second control system with a signal indicating the change in the feed adjuster and which is compared with the deviation from the index value and ceases to activate the feed adjuster when a predetermined change is reached therein. The appts. is also claimed. Used for adding CO2 with a concentrate to mineral waters, etc., and produces a standard mixt. without hunting of ...

本发明提供了一种连续化气液反应装置及含有其的连续化气液反应系统。连续化气液反应装置包括:主反应器、搅拌装置和振荡源。搅拌装置设置于主反应器的内部,且沿主反应器的长度方向延伸;振荡源用于控制主反应器的振荡频率。上述连续化气液反应装置中同时设置有搅拌装置和振荡源,在二者的同时作用下,主反应器中会形成轴向和径向的复杂漩涡,同时随着振荡的进行,漩涡不断出现消失。这能够使主反应器中的流型更加复杂,强化液液传质,进而使反应更加充分,同时提高主反应器的传热效果。振荡源的存在使得体系在器壁和搅拌装置之间剧烈地反复冲刷能够有效抑制反应过程中出现粘接堵塞的风险。
