    • A remotely controlled line conditioning apparatus is installed in the terminal where access to the telephone loop to be tested is readily available. Although a metallic bypass pair from the central office to the (remote) terminal may also be available, its presence and/or condition does not affect the ability of the apparatus to condition the line under test. The line conditioning apparatus includes a telephone line termination unit and an intelligent control unit. The telephone line termination unit has a telephone line access port to which a telephone line pair is selectively coupled, and is operative to controllably impart a selected one of a plurality of electrical signalling conditions to the telephone line pair under test. The control unit has a communication modem through which communication signals containing telephone line conditioning messages are coupled to and from the central office/remote terminal communication link. The control unit also includes a micro-controller, which is coupled to the modem, for generating telephone line unit control signals in response to line conditioning messages from a host unit located at the central office. Control signals generated by the micro-controller control the operation of the telephone line termination unit which conditions the telephone line pair.
    • 在终端中安装有远程控制的线路调节装置,其中容易获得要被测试的电话回路的接入。 虽然从中心局到(远程)终端的金属旁路对也可能可用,但其存在和/或状况不影响设备调节待测线路的能力。 线路调节装置包括电话线路终端单元和智能控制单元。 电话线路终端单元具有电话线路接入端口,电话线路对被选择性地耦合到该电话线路接入端口,并且可操作地将可选地将多个电信号状态中的一个电信号状况赋予被测电话线对。 控制单元具有通信调制解调器,通过该通信调制解调器,包含电话线路调理消息的通信信号通过该通信调制解调器耦合到中央局/远程终端通信链路。 控制单元还包括耦合到调制解调器的微控制器,用于响应于来自位于中心局的主机单元的线路调节消息而产生电话线路单元控制信号。 由微控制器产生的控制信号控制电话线路对的电话线终端单元的操作。

    • Disclosed is a ventilator including a heat exchanger having a fresh air channel and a stale air channel. The respective channels are pneumatically isolated, but, are arranged in contiguous and interwoven fashion such that incoming fresh air may pass in countercurrent heat exchange relation to the outgoing stale air twice. The fresh air channel has an inlet in communication with air external to the ventilated space and an outlet in communication with the ventilated space. The stale air channel has an inlet in communication with the ventilated space and an outlet in communication with the external space. The heat exchanger features heat transfer means in communication with the fresh and stale air channels which is formed by a septum having a first surface in heat exchange relation with the fresh air channel and a second surface in heat exchange relation with the stale air channel. The septum is wrapped in successive spaced turns to form alternating sections of the fresh air and stale air channels. The resulting combination of channel sections has a generally elliptically shaped profile, and includes two pseudo foci at one of which the fresh air outlet is located and at the other of which the stale air inlet is located. The fresh air inlet and the stale air outlet are locates at the other respective channel ends.
    • 公开了一种通风机,其包括具有新鲜空气通道和陈旧空气通道的热交换器。 相应的通道是气动隔离的,但是以相邻和交织的方式布置,使得进入的新鲜空气可以与输出的陈旧空气逆流热交换两次。 新鲜空气通道具有与通风空间外部的空气连通的入口和与通风空间连通的出口。 陈旧的空气通道具有与通风空间连通的入口和与外部空间连通的出口。 热交换器具有与新鲜和陈旧的空气通道相连通的传热装置,其由具有与新鲜空气通道热交换的第一表面的隔膜和与陈旧空气通道热交换的第二表面形成。 隔膜以连续间隔的匝包裹,形成新鲜空气和陈旧空气通道的交替部分。 所得到的通道部分的组合具有大致椭圆形的轮廓,并且包括两个伪焦点,其中新鲜空气出口位于其中一个处,而另一个位于陈旧的空气入口的另一个。 新鲜空气入口和陈旧的空气出口位于其他各个通道端。
