摘要： In the texturing unit of this invention a data storage disk is gripped between a pair of opposed, counter-rotating cylindrical abrasive mandrels, which are covered with soft, porous pads. The frictional force between the disk and the pads raises the edge of the disk against a pair of driven rollers which impart a rotational motion to the disk. A texture pattern of uniform grooves, having controlled peak heights and valley depths, is formed simultaneously on both sides of the disk. A system for delivering an abrasive slurry to the pads includes a closed loop in which the slurry is recirculated and a dispense section of that loop, from which a blast of pressurized air periodically expels the slurry through applicators and onto the pads. The continuous recirculation of the slurry prevents settling.A unique feature is that the groove length may be controlled by adjusting the ratio between the rotational speeds of the disk and mandrels. The groove pattern is primarily circular but a radial component may be added by varying the position at which the pads contact the surfaces of the disk.

摘要翻译： 在本发明的纹理单元中，数据存储盘被夹在一对相对的反向旋转的圆柱形磨料心轴之间，其被柔软的多孔垫覆盖。 盘和垫之间的摩擦力使盘的边缘抵靠一对驱动辊，这些从动辊向盘提供旋转运动。 在盘的两侧同时形成具有受控峰高和谷深度的均匀凹槽的纹理图案。 用于将磨料浆料输送到衬垫的系统包括闭合回路，其中浆料被再循环，并且该循环的分配部分，加压空气鼓风从该循环周期性地排出浆料通过施加器并且到达衬垫。 浆料的连续再循环防止沉降。 一个独特的特征是可以通过调节盘和心轴的转速之间的比例来控制槽长度。 凹槽图案主要是圆形的，但是可以通过改变垫接触盘表面的位置来添加径向分量。

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： A detector for detecting the presence of an electrically conductive sample solution in a sample injection metering valve by electrical sensing the leading edge of the sample solution, wherein the amount of sample solution in excess of the metered amount required to cause detection is minimized. A conductive probe is positioned on the valve body just downstream of the sample metering passage of the valve, the probe being electrically insulated from the valve body. The probe and valve body form electrodes which will detect the arrival of the leading edge of a conductive sample solution which completes a conductive circuit between the electrodes.

摘要： A temperature control apparatus for a high temperature reactor in an analytical instrument of the type in which a development reagent is added to a flowing stream as part of the detection process. The temperature control apparatus utilizes solid state heat transfer means to transfer heat between a thermoconductive block to which is mounted the reactor and an air exchange heat sink which obtains heat from or disposes heat into ambient air as required. The control apparatus regulates the temperature of the reactor at a very rapid rate in the high temperature range of approximately 90.degree. C. to 150.degree. C. without the use of a separately contained heat exchange medium. The ability of the apparatus to cool the reactor rapidly eliminates the requirement to keep reactor contents at elevated pressures to prevent vaporization of the stream being analyzed.

摘要： An elongate straight column for use as a reactor in an analytical instrument. The column contains inert packed material which provides for the necessary flow path length for a fluid stream entering the reactor. Fittings are incorporated onto the ends of the column in such a manner that their width is no larger than the width of the column. The column configuration for a reactor allows more versatility in the type of temperature regulator mechanisms used to heat and cool the reactor.

摘要： A method and apparatus for monitoring flow rate through a conduit. A flow number indicative of the flow rate of a liquid through the conduit is compared with a preselected reference number. The actual liquid flow through the conduit provides a clocking signal which determines the time span during which a count signal, indicative of the intended flow rate into the conduit, is accumulated thereby providing the flow number.

摘要： Liquid is removed from wafers for drying a wafer that has been wet in a liquid bath. The wafer and the bath are separated at a controlled rate as the wafer is positioned in a gas-filled volume. The controlled rate is generally not less than the maximum rate at which a meniscus will form between the liquid bath and the surface of the wafer when the liquid bath and the wafer are separated. The gas-filled volume is defined by a hot chamber that continuously transfers thermal energy to the wafer in the gas-filled volume. Hot gas directed into the volume and across the wafer and out of the volume continuously transfers thermal energy to the wafer.

摘要： A composite bipolar electrode structure is described. The structure includes an anode face comprised of a layer of a platinum group metal, metal oxide, or mixtures thereof, deposited on a layer of a valve metal, preferably titanium, a cathode face comprised of a cathode material, suitably a ferrous material, and an intermediate layer of conductive, porous material, such as graphite, positioned to be in electrical contact between the valve metal layer and the cathode material layer. The electrode is assembled by applying a thin layer of a polymeric material on the interfaces of the porous intermediate layers and pressing the components with sufficient pressure to force the polymeric material into the interstices of the intermediate layers.
