    • This invention relates to a clip or fastening device for assembly with a channel shaped structural member adapted to be self clamping adjacent one side wall of the channel member for supporting a structural component. The clip includes a body portion which projects from the side wall of the channel having one end thereof provided with prongs which engage beneath the inturned flange on the side wall and an extension which projects toward the base of the channel and terminates in prongs for engaging the same. The clip is resiliently held in position in the channel member between the spaced set of prongs. A suitable attaching member formed either integrally with the body portion or separate therefrom is adapted to receive the edge portion of the wall of the component and secure it to the clip.

    • A railway crossing signalling system using coded digital signals impressed on the tracks for actuation of a crossing relay, the presence of a train at the crossing location causing shunting of the signals and an indication from the relay which operates in a fail-safe configuration. In each signal circuit first and second tone oscillators provide carrier signals which are modulated in a specific digital pattern and applied to the tracks. A tone sensitive receiver separately detects the carrier signals and provides pulse train outputs which are decoded in a binary counter and coincidence gate circuit for ascertainment that the correct digital code pattern has been received. Signals are developed for energization of an oscillator, the output of the latter being amplified for direct actuation of the crossing relay. More than one signal circuit can be employed on common tracks for separate or overlapping signal control by the selection of different pairs of operating frequencies, readily accommodated by plug-in filter substitution.
    • 使用编码数字信号的轨道交叉信号系统,其被施加在轨道上用于致动交叉继电器,在交叉位置存在导致信号分流的列车,以及来自以故障安全配置运行的继电器的指示。 在每个信号电路中,第一和第二音调振荡器提供以特定数字图案调制并施加到轨道的载波信号。 音敏接收机分别检测载波信号并提供脉冲序列输出,该输出在二进制计数器和重合门电路中解码,以确定已经接收到正确的数字码型。 信号被开发用于激励振荡器,后者的输出被放大以用于直接致动交叉继电器。 通过选择不同的工作频率对,通过插入式滤波器替换可以容易地容纳多个信号电路,用于单独或重叠的信号控制。
