Abstract: A photometric flow cell for high pressure liquid chromatography having an illuminated passageway therein between open ends of which fluid samples are flowed for analysis. An annular, porous flow impedance element is supported in an annular channel surrounding one end of the passageway. The impedance element reduces turbulence of flow through the open end by evenly distributing the flowing fluid circumferentially about the end opening.

Abstract: A system for remotely controlling one or more instruments from a control terminal. Each instrument includes a stored menu of operations it can perform under control of the terminal and an accumulator for producing an index number which selects a particular operation from the menu. The terminal includes means for transmitting commands to direct the instrument to increment the index number and to transmit back to the terminal a textual description of the currently selected menu entry. The terminal further includes means for directing the instrument to perform the operation designated by the current menu entry.
Abstract translation: 一种用于从控制终端远程控制一个或多个仪器的系统。 每个仪器包括其可在终端控制下执行的操作的存储菜单和用于产生从菜单中选择特定操作的索引号的累加器。 终端包括用于发送命令的装置，用于指示仪器增加索引号码，并向终端发送当前选择的菜单条目的文本描述。 终端还包括用于引导仪器执行由当前菜单条目指定的操作的装置。

Abstract: A pressure booster system for fluids using one or more injectors for delivering a relatively low pressure output flow of fluid. A fluid accumulator receives the output from one or more injectors. A detector reveals any fluid mass change in the accumulator in relation to a selected value of fluid mass. A relatively high pressure pump increases the pressure of the output flow from the accumulator in accordance with the change of fluid mass within the accumulator which results in high pressure metering.
Abstract translation: 一种用于使用一个或多个喷射器输送流体的相对低压输出流的流体的增压系统。 流体蓄能器接收来自一个或多个喷射器的输出。 检测器显示相对于液体质量的选定值的蓄能器中的任何流体质量变化。 相对较高的压力泵根据蓄能器内的流体质量的变化而增加来自蓄能器的输出流的压力，这导致高压计量。
