    • A roof anchor including a pair of blocks positioned side-by-side. The blocks have adjacent, inner surfaces with notches cut therefrom for receiving a standing seam of a metal roof. The blocks also have outer surfaces remote from the inner surfaces. A bracket is positioned over the pair of blocks. The bracket includes a base portion having a pair of legs, each being positioned adjacent a respective one of the outer surfaces of the blocks, and a crosspiece, positioned adjacent the tops of the blocks, joining the legs together. A loop portion is affixed to the base portion for securement of a workman's safety lanyard. A threaded fastener penetrates the pair of blocks and the pair of legs for: fastening the pair of blocks together, securing the bracket to the pair of blocks, and clamping the pair of blocks upon a standing seam of a metal roof.

    • Embodiments of the invention include methods, apparatus, systems and means for distinguishing between microphone line signals resulting from: actuation of a microphone button of a headset plugged into a telephone device jack, and removal of the headset plug form the jack. During a telephone call, a first signal can be detected on a microphone line of a headset jack to indicate whether a microphone button of the headset is actuated. Also, while the headset plug is being disconnected from the jack, a transition on the microphone line can be detected, from a second signal indicating that the microphone is being disconnected, to a third signal indicating that the microphone button is actuated. Consequently, to avoid erroneously hanging up a call, transitions to the third signal when removing the plug form the jack can be ignored and the call can be maintained. Other embodiments are also described and claimed.
    • 本发明的实施例包括用于区分麦克风线路信号的方法,装置,系统和装置,所述麦克风线路信号是:插入到电话设备插孔中的头戴式耳机的麦克风按钮的致动以及从插座移除耳机插头。 在电话呼叫期间,可以在耳机插孔的麦克风线上检测第一信号,以指示耳机的麦克风按钮是否被致动。 此外,当耳机插头与插孔断开连接时,可以从指示麦克风被断开的第二信号检测到麦克风线上的转换到指示麦克风按钮被致动的第三信号。 因此,为了避免错误地挂断呼叫,可以忽略从插头拔出插头时转换到第三信号,并且可以保持呼叫。 还描述和要求保护其他实施例。

    • A dual-stream book pivot machine is provided which turns books moved therealong 90.degree. to present a labeling area thereon in proper orientation and includes belts for moving the books downstream and a stop positioned in the path of the books moving therealong. Two parallel streams are preferably provided so that books, which have their greatest surface resting in engagement with the belts, can move in side-by-side relationship, each being turned to avoid interference with the books in the adjacent stream. The stops are positioned at one side of the belts for moving the books, the stop thus creating a point about which the books pivot and move laterally at least the width of the stop. The stop is elongated to present a guide preventing spinning of the pivoted books and thereby retaining the books in the proper orientation for handling by machines located downstream therefrom.
    • 提供了一种双流书本枢纽机器,使书本在90度移动,在其上以适当的方向呈现标签区域,并且包括用于移动书籍下游的皮带和位于沿着书籍移动的书籍路径中的停止点。 优选地提供两个平行的流,使得具有与皮带接合的最大表面的书可以并排移动,每一个都转动以避免与相邻流中的书干涉。 挡块位于皮带的一侧,用于移动书本,止动件因此产生书本枢轴转动的点,至少横向移动止挡件的宽度。 止挡件是细长的,以提供防止旋转书籍旋转的引导件,从而将书本保持在正确位置以便由位于其下游的机器处理。
