摘要： A light beam is passed through a cuvette, through which flows liquid to be analyzed optically for concentration of color reacted amino acids. The emergent beam is directed through a series of dichroic beam separators and pass band filters to produce three beams of substantially three different wavelengths. Photoelectric detectors produce electrical signals corresponding to each of the three wavelengths. Two of the signals are characteristic of the substance to be detected. The third is subtracted from the other two wavelength signals to produce a pair of output signals from which base line noise has been substantially eliminated.

摘要： An air driven centrifuge including a rotor chamber having a rotor seat mounted in the bottom thereof and including a rotor having a plurality of turbine flutes formed in an under side thereof. The rotor seat includes driving air jet means for impinging pressurized air streams against the turbine flutes of the rotor for supporting and spinning the rotor on an air cushion above the rotor seat. Support air jet means are also provided in the seat for directing pressurized air streams against the under side of the rotor for supporting the rotor when the driving air jet streams are inactivated. A brake and stabilizing means is included for decelerating the spinning rotor and includes a friction bearing means on the bottom portion of the rotor and a stabilizer means movable into engagement with the bearing means and cooperating with the bearing means to produce a frictional load against the bearing means thereby causing the rotor to decelerate and also stabilizing the rotor as it slows to a stop.
摘要翻译：一种空气驱动的离心机，包括具有安装在其底部的转子座的转子室，并且包括转子，该转子具有形成在其下侧的多个涡轮槽纹。转子座包括驱动空气喷射装置，用于将加压空气流冲击转子的涡轮槽，用于将转子支撑并旋转在转子座上方的气垫上。支撑空气喷射装置也设置在座中，用于将压缩空气流引导到转子的下侧，用于当驱动空气喷射流失活时支撑转子。包括用于使旋转转子减速的制动器和稳定装置，并且包括在转子的底部上的摩擦支承装置和可与轴承装置接合并与轴承装置协作以产生抵靠轴承的摩擦负载的稳定装置意味着由此使得转子减速并使转子在停止时变得稳定。
