    • The adaptive temperature controller includes an ambient temperature sensor, a device for measuring resistance, an electrically-conductive material, a power supply, and a device for controlling power. In operation, the controller determines the resistance of material at or near ambient temperature. Based on such determination so long as voltage and power are known, the resistance of the material, and therefore its instant temperature is known. Additionally, the adaptive temperature controller determines the responsiveness of the electrically-conductive material to determine the predicted increase in temperature and rate of increase in temperature relative to increases in voltage, current or power. As a result the voltage or power may be instantly varied to produce near infinite control over material temperature.
    • 自适应温度控制器包括环境温度传感器,用于测量电阻的装置,导电材料,电源以及用于控制功率的装置。 在操作中,控制器确定材料在环境温度或接近环境温度时的电阻。 基于这样的确定,只要电压和功率已知,材料的电阻以及其即时温度是已知的。 此外,自适应温度控制器确定导电材料的响应性以确定相对于电压,电流或功率的增加的温度预测增加和温度升高速率。 因此,电压或功率可能立即变化,从而对材料温度产生接近无限的控制。

    • The illustrated and preferred embodiment of the present invention is a sample delivery system for packed or open tubular column gas chromatographic apparatus. The apparatus comprises a sample injection valve constructed and arranged to utilize multiple ports wherein a gaseous or liquid sample is injected through a syringe into an injection port, the valve being heated to volatilize the sample which is then temporarily stored in a sample storage loop. The valve apparatus rotates to connect the sample storage loop with an inlet conduit delivering the sample and sweep gas to an exponential dilution flask (EDF). The flask provides an output which delivers a diluted portion of sample with the extent of dilution controlled as a function of time through a second valve assembly. The second valve assembly is switched with a timer to deliver a portion of the sample flow and sweep gas to a capillary bore gas chromatographic apparatus. The first valve may also be used independently as an off-line, septumless inlet for use with packed columns without the dilution stage.
    • 本发明的示例和优选实施方案是用于打包或打开管状柱状气相色谱仪的样品递送系统。 该装置包括构造和布置成利用多个端口的样品注射阀,其中气体或液体样品通过注射器注入到注射端口中,该阀被加热以使样品挥发,然后临时存储在样品储存环中。 阀装置旋转以将样品储存环与将样品和吹扫气体送至指数稀释瓶(EDF)的入口导管连接。 烧瓶提供输出,其输送稀释的样品部分,其稀释程度通过第二阀组件作为时间的函数被控制。 用定时器切换第二阀组件,以将一部分样品流和吹扫气体输送到毛细管孔气相色谱仪。 第一个阀也可以独立地用作离线的无隔膜入口,用于没有稀释阶段的填充柱。

    • An adaptor assembly is disclosed in two embodiments. Each embodiment is for connecting a tubing to a fitting of different size. The alternate embodiment is similar to the first embodiment except that it cooperates with a male fitting as opposed to a female fitting. In the embodiment for connection to a female fitting, a hollow threaded nut drives a tapered spool into a tubular seat, and the tubing is placed on the interior of the nut, spool and seat. All of this is placed in a hollow threaded adaptor which abuts a larger tapered spool, all of which threads into the female fitting. When the components are threaded together, they squeeze and clamp the tubing. The tubing, once clamped, is held securely and cannot be pulled free. The threaded adaptor has a wall thickness enabling it to mate with a fitting of any suitable size. The male counterpart equipment is similar in construction except that the adaptor coupling is provided with two sets of threads arranged respectively at countersunk internal axial portions to receive a male fitting thereinto.
    • 在两个实施例中公开了适配器组件。 每个实施例用于将管道连接到不同尺寸的配件。 替代实施例类似于第一实施例,除了它与阳配件相对于阴配件相配合。 在用于连接到阴配件的实施例中,空心螺纹螺母将锥形阀芯驱动到管状座中,并将管道放置在螺母,阀芯和阀座的内部。 所有这些都被放置在中空螺纹适配器中,该适配器邻接较大的锥形阀芯,所有螺纹适配器都进入阴配件。 当组件拧在一起时,它们挤压并夹紧管道。 管子一旦被夹紧就牢固地固定,不能被拉出。 螺纹适配器具有壁厚,使其能够与任何合适尺寸的配件配合。 男性对应设备的结构相似,除了适配器联接器设置有分别安装在埋头内部轴向部分处的两组螺纹以接收其中的公配件。
