    • A method of cleaning potable liquid flow lines employing a high pH caustic cleaning solution or a low pH acid cleaning solution with a stable dye in sufficient concentration so as to have a visible color when the solution is further diluted. The cleaning solution is pumped through the lines. The lines then are flushed with clean water until no colored solution is discharged from the lines, indicating the lines have been purged of cleaning solution. The method can be used with draft beer, soft drink or other potable liquid flow lines to prevent inadvertent consumption of caustic cleaning solution along with subsequently dispensed potable liquid.

    • In a loop-structured communication system interconnecting a plurality of data processors without central controller, stations comprise modems which can start loop operation and achieve synchronous frame transmission around the loop through all participating stations.In an initialization procedure after system start or after loss of frame synchronization on the loop, modems select a temporary master station.The temporary master will adapt total loop delay to be an integer multiple of the basic frame period, and will transmit available frames. All active modems adapt their timing to the circulating stream of frames until the whole loop and all participating stations are synchronized.Synchronization conditions are continuously monitored in all stations to start resynchronization or initialization procedures if necessary. In a specific arrangement, the location of a loop failure which prevents establishment of synchronization can be determined.All initialization and synchronization operations are handled by the modems without participation by other functional units or by the host processing system of any station.
    • 在不具有中央控制器的多个数据处理器互连的环路结构化通信系统中,站包括调制解调器,其可以开始循环操作,并通过所有参与站实现循环周期的同步帧传输。 在系统启动或循环丢帧后的初始化过程中,调制解调器选择一个临时主站。 临时主设备将总循环延迟调整为基本帧周期的整数倍,并传送可用帧。 所有活动的调制解调器将其时序调整到循环的帧流,直到整个循环和所有参与站同步。 在所有站点中连续监视同步条件,以便在必要时启动重新同步或初始化程序。 在具体的布置中,可以确定防止建立同步的环路故障的位置。 所有初始化和同步操作都由调制解调器处理,而不受其他功能单元或任何站的主机处理系统的参与。

    • A transformerless power supply and display energizing circuit for a clock circuit with a duplex optoelectronic display driven by a low voltage integrated clock circuit having positive and negative voltage input terminals and the duplex display having a first terminal connected to a first common cathode and a second terminal connected to a second common cathode of the display for energizing it. The transformerless circuit is powered from an AC source. An impedance, which may be either resistive or reactive, reducing the AC voltage to a level suitable for the integrated clock circuit. The transformerless circuit generates synchronous DC level-shifted pulse trains for driving the positive input terminal of the integrated clock circuit alternately between a first voltage and a reference voltage while synchronously driving the display first terminal between said first voltage and a voltage of equal amplitude and opposite polarity. The display second terminal is held at the reference voltage.

    • In a ring-structured data communication network, in which plural data processing systems exchange data and control information on a full duplex peer to peer basis, systems are presently architected to assign at least three I/O subchannels (i.e. at least three device addresses) to respective ring interface adapters. At least two of these subchannels are dedicated for providing separate input paths from the ring to at least two associated program-assignable areas in their system's main store, and a third of these subchannels is dedicated as an output path from the system's store to the ring. Collectively, these subchannels can sustain two input transfer processes and one output transfer process concurrently. One of these input processes is associatable with a locked mode of adapter operations which provides a non-blockable path for data transfer from a selected (remote) station on the ring to the respective system's main store. In this mode the other input subchannel and the output subchannel permit the system to maintain full duplex communication with other ring stations in respect to network transactions/processes which may require priority attention. Information is sent on the ring in discrete information frames of variable bit length, each frame acknowledged by a response frame. In general, response frames have much shorter bit lengths than the information frames, enabling the systems to access the ring more efficiently than they would be able to if response and information frames had equal lengths.
    • 在其中多个数据处理系统在全双工对等的基础上交换数据和控制信息的环形结构化数据通信网络中,系统目前被设计为分配至少三个I / O子信道(即至少三个设备地址) 到相应的环形接口适配器。 这些子信道中的至少两个专用于在其系统的主存储器中提供从环到至少两个相关联的程序可分配区域的单独输入路径,并且这些子信道中的第三个专用为从系统存储到环的输出路径 。 总的来说,这些子通道可以同时维持两个输入传输过程和一个输出传输过程。 这些输入过程中的一个与适配器操作的锁定模式相关联,其提供用于从环上的选定(远程)站到相应系统的主存储器的数据传输的不可阻塞路径。 在该模式中,另一个输入子信道和输出子信道允许系统在与可能需要优先关注的网络事务/过程方面保持与其他环站的全双工通信。 信息在可变位长度的离散信息帧中在环上发送,每帧由响应帧确认。 通常,响应帧具有比信息帧短的位长度,使得系统能够比如果响应和信息帧具有相等长度能够更有效地访问环。

    • A method of initializing non-synchronous peer-to-peer data communication rings, and for effecting error recovery in such networks. On detection of error, each station operates in a purging configuration to clear the ring. In the purging configuration the station's receiving circuits are isolated and its transmitting circuits transmit "clear" signals containing this station's own address as destination. These signals serve to purge all potentially erroneous information in all upstream stations which then are operationally connected to that station. If a loss condition is persistent the station operates first in a "bypass" configuration for a third predetermined time interval, then in the purging configuration for the second time interval, and then resumes normal operation. In the bypass configuration the station's ring input is connected directly to its output and the (locally clocked) output of its transmitting circuits is connected to the input of its receiving circuits. This serves to restore reception clocking in temporary alignment with the local transmission clock source. When a station switches from purging mode to normal operation it resumes monitoring its reception synchronism. If is fails to develop synchronism it repeats the foregoing recovery procedure.
    • 初始化非同步对等数据通信环的方法,并在这种网络中实现错误恢复。 在检测到错误时,每个站都以清洗配置运行,以清除环。 在清洗配置中,站的接收电路是隔离的,其发送电路将包含该站自身地址的“清除”信号作为目的地传送。 这些信号用于清除所有上游站中的所有潜在的错误信息,然后这些信息可操作地连接到该站。 如果丢失条件持续,则站首先在“旁路”配置中运行第三预定时间间隔,然后在第二时间间隔的清除配置中,然后恢复正常操作。 在旁路配置中,站的环路输入直接连接到其输出,并且其发射电路的(本地时钟)输出连接到其接收电路的输入。 这用于恢复与本地传输时钟源临时对准的接收时钟。 当站从清除模式切换到正常操作时,它恢复监视其接收同步。 如果不能同步发展,则重复上述恢复过程。
