    • Mini-wall parapet structures are disclosed. The structures are of one piece sheet metal with four sided, longitudinal members. A cleat extends downwardly from a lower corner of the structure. The cleat may be a single layer of sheet metal or a folded over layer. The cleat engages a coping member at final installation, and provides an additional attachment for the structure. A folded over primary attachment layer extends from the other lower corner of the structure. The attachment layer is of variable width so that different roof surfaces can be accommodated. The cross section of the structure is either square, or rectangular with longer vertical walls. Rectangular structures are used with thicker insulation. A facade extension may be used with rectangular structures. The top wall includes a gravel guard. The hollow void may be further filled with insulation.
    • 公开了迷你墙壁护栏结构。 该结构是具有四边形纵向构件的一片金属片。 防滑板从结构的下角向下延伸。 防滑板可以是单层金属板或折叠层。 在最终安装时,防滑板接合应对构件,并为结构提供附加附件。 折叠的主附着层从结构的另一个下角延伸。 附着层具有可变宽度,从而可以容纳不同的屋顶表面。 结构的横截面是方形或矩形,具有较长的垂直壁。 矩形结构使用较厚的绝缘。 立面延伸可以与矩形结构一起使用。 顶墙包括一个砾石防护装置。 中空空隙可以进一步填充绝缘体。

    • High-speed data streams are exchanged between two digital computing devices one or both of which lacks DMA. Data transfers are performed by the devices using High-Level Datalink Control (HDLC) frames. An initiating device indicates that it wishes to exchange data with the other device by sending an HDLC frame with data stream indentification and other information. The initial HDLC frame is sufficiently short that at least an essential portion of the frame can be stored in a receive buffer of the interface circuitry. Although the receiving device may not receive the entire HDLC frame correctly because of the possibility of an overrun condition, enough information is preserved in the interface circuitry to complete the transaction. The responding device then proceeds to read or write data at high speed using a series of exchanges with the initiating device.
    • 在两个数字计算设备之间交换高速数据流,其中一个或两个缺少DMA。 数据传输由使用高级数据链路控制(HDLC)帧的设备执行。 启动设备指示希望通过发送具有数据流标识和其他信息的HDLC帧来与其他设备交换数据。 初始HDLC帧足够短,使得帧的至少一个基本部分可以存储在接口电路的接收缓冲器中。 虽然接收设备由于可能出现溢出状况而不能正确地接收整个HDLC帧,但在接口电路中保留足够的信息来完成交易。 响应装置然后使用与发起装置的一系列交换来高速读取或写入数据。
