    • Components of a chemical processing system are disclosed. In particular, a chemical processing system is disclosed which includes a chemical mixing or reacting zone, an inlet to the zone, an outlet to the zone, and a vacuum or fluid flow source located downstream of the outlet. The chemical processing system further includes a device to control the amount of vacuum or fluid flow through the zone. Also disclosed is a continuous feeder system having a first loss-in-weight and a second loss-in-weight feeder and a device for measuring a lower limit of feed in each feeder. There is also a device to activate the second feeder when the lower limit is obtained in the first feeder and a device to deactivate the first feeder when the lower limit is detected in the first feeder. A sample port assembly is also disclosed for obtaining a sample of material flowing through a processing system. The sample port assembly includes a port in the assembly and a sample cup holder adapted to be moved in the port to obtain a sample of material without substantially affecting the fluid pressure or flow within the system. The components of the chemical processing system can be used in processes to make carbon black having attached organic groups.
    • 公开了一种化学处理系统的组件。 特别地,公开了一种化学处理系统,其包括化学混合或反应区,到该区域的入口,到该区域的出口以及位于出口下游的真空或流体流动源。 化学处理系统还包括用于控制通过该区域的真空或流体流量的装置。 还公开了具有第一重量损失和第二丢失重量进料器的连续进料系统和用于测量每个进料器中进料下限的装置。 当在第一供料器中获得下限时,还有一个用于启动第二供料器的装置,以及当在第一供料器中检测到下限时停用第一供料器的装置。 还公开了一种样品端口组件,用于获得流过处理系统的材料样品。 样品端口组件包括组件中的端口和适于在端口中移动以获得材料样品而不显着影响系统内的流体压力或流动的样品杯保持器。 化学处理系统的组分可以用于制备具有附着有机基团的炭黑的方法中。

    • A switch assembly (20) comprising of a base portion (22), a flexible pad (24), a paddle (26), and at least one button (28). The flexible pad (24) has a first dome (44) and a second dome (46). The paddle (26) is slidably attached to the base portion (22) and has a first end portion (64) and a second end portion (66). The first end portion (64) of the paddle (26) is positioned adjacent to the first dome (44) of the flexible pad (24). The second end portion (66) of the paddle (26) is positioned adjacent to the second dome (46) of the flexible pad (24). The button (28) is slidably attached to the base portion (22) and is capable of contacting the paddle (26). The first dome (44) of the flexible pad (24) is capable of collapsing when a user applies a first force (FA) to the button (28). The second dome (46) of the flexible pad (24) is capable of collapsing when the user applies a second force (FB) to the button (28), the second force (FB) being greater in value than the first force (FA). The switch assembly (20) may further include a white light emitting diode (80) for providing a colored light for the switch assembly (20) through the use of the flexible pad (24).
    • 一种开关组件(20),包括基部(22),柔性垫(24),桨(26)和至少一个按钮(28)。 柔性垫(24)具有第一圆顶(44)和第二圆顶(46)。 桨(26)可滑动地附接到基部(22),并具有第一端部(64)和第二端部(66)。 桨(26)的第一端部(64)定位成与柔性垫(24)的第一圆顶(44)相邻。 桨(26)的第二端部(66)定位成与柔性垫(24)的第二圆顶(46)相邻。 按钮(28)可滑动地附接到基部(22)并且能够接触桨(26)。 当用户将第一力(FA)施加到按钮(28)时,柔性垫(24)的第一圆顶(44)能够折叠。 当用户将第二力(FB)施加到按钮(28)时,柔性垫(24)的第二圆顶(46)能够塌缩,第二力(FB)的值大于第一力(FA )。 开关组件(20)还可以包括白色发光二极管(80),用于通过使用柔性垫(24)为开关组件(20)提供彩色光。
