    • A system and method are disclosed for the grinding of industrial minerals to fine powders. The system includes a grinding chamber having a generally vertically oriented agitator that is rotated to stir the grinding media intermixed with a feedstock. As the agitator stirs the grinding media and feedstock, there is a retaining plate that is also located within the grinding chamber and positioned atop of the grinding media to prevent the expansion of the grinding media when it is being stirred. The retaining plate has one or more openings to allow the finely ground feedstock to pass upwardly therethrough but to prevent any grinding media from passing through the retaining plate. Introduction of the feedstock may be through one or more hollow support rods that locate the retaining plate in the desired location within the grinding chamber. The support rods are locked into position when the retaining plate is properly located.
    • 公开了一种将工业矿物研磨成细粉末的系统和方法。 该系统包括具有大致垂直取向的搅拌器的研磨室,其被旋转以搅拌与原料混合的研磨介质。 当搅拌器搅动研磨介质和原料时,还有一个保持板,其也位于研磨室内并定位在研磨介质的顶部,以防止研磨介质在被搅拌时膨胀。 保持板具有一个或多个开口,以允许精细研磨的原料向上通过,但是防止任何研磨介质通过保持板。 原料的引入可以通过将保持板定位在研磨室内所需位置的一个或多个中空支撑杆。 当保持板正确定位时,支撑杆被锁定就位。

    • A method and system for blocking an incoming telephone call based upon at least one predetermined criterion. The system includes a security device having a user device for imputting a first control signal to block the incoming telephone call, and for inputting a second control signal for controlling at least one feature of the security system, at least one sensor for detecting an emergency event within a protected area. The sensor generates an alarm signal. The system further includes a control section for processing the first and second control signals. The control section generates a control signal based upon the first control signal. Based upon this control signal, a line seizure means opens or closes a connection between an incoming telephone line and a telephone device. The security system has continuous access to the incoming telephone line, even though the line can be isolated from the telephone device.
    • 一种用于基于至少一个预定标准来阻止呼入电话的方法和系统。 该系统包括具有用于输入第一控制信号以阻止进入电话呼叫的用户设备的安全设备,以及用于输入用于控制安全系统的至少一个特征的第二控制信号,用于检测紧急事件的至少一个传感器 在保护区内。 传感器产生报警信号。 该系统还包括用于处理第一和第二控制信号的控制部分。 控制部根据第一控制信号生成控制信号。 基于该控制信号,线路发送装置打开或关闭输入电话线路和电话设备之间的连接。 即使该线路可以与电话设备隔离,安全系统也可以连续接入电话线路。
