    摘要： The invention relates to and an apparatus for measuring the distance between two spaced objects and wherein either or both of said objects may be movable with respect to each other and/or with respect to a fixed point. Said objects, such as vehicles arranged along a track, each carry a transmitter for the emanation of signals and a receiver for the reception of signals emanated by an adjacent object. The signals are fed to a conductor extending along said track and able to provide a sufficiently rapid attenuation of said signals whereby same may serve as an accurate indicator of relatively short distances between the objects. For example, such conductor can comprise at least two parallel conductors connected throughout their length by resistive means of relatively high conductivity. Supplemental transmitters may also be applied to said objects to suppress transmitted signals in one direction while permitting such transmission in another direction in order to minimize interference with the signal received from another object, as a vehicle, in the one direction. Thus, in a line of three vehicles, the transmitter on the second vehicle will not interfere with the receiver on the second vehicle but will effectively send signals to the receiver of the third vehicle.

    摘要翻译： 本发明涉及一种用于测量两个间隔物体之间的距离的装置，并且其中所述物体中的一个或两个可以相对于彼此和/或相对于固定点可移动。 所述物体，例如沿着轨道布置的车辆，每个都携带用于发出信号的发射机和用于接收相邻对象发出的信号的接收机。 信号被馈送到沿着所述轨道延伸的导体，并且能够提供所述信号的足够快的衰减，从而相同的信号可以用作物体之间相对短的距离的精确指示。 例如，这种导体可以包括通过相对高导电性的电阻装置在其整个长度上连接的至少两个平行导体。 补充发射机也可以应用于所述对象，以在一个方向上抑制发射的信号，同时允许在另一个方向上的这种传输，以便最小化对从另一物体作为车辆在一个方向上接收的信号的干扰。 因此，在三个车辆的行中，第二车辆上的发射机不会干扰第二车辆上的接收机，而是将有效地向第三车辆的接收机发送信号。

    摘要： A multi-conductor cable for forming a cable harness, for instance for use in automobiles or aircraft, comprises at least one length of tape cable enclosed in a heat-shrunk tubular sheath of insulating material. At least one branch length of tape cable is electrically connected to the length of tape cable, or to at least one of the lengths of tape cable, at at least one of a number of longitudinally spaced locations, the free end of the branch length protruding from the tubular sheath. An individually insulated conductor and/or a twin or multi-conductor insulated cable may also be enclosed within the tubular sheath. In a cable harness incorporating the multi-conductor cable at least some of the conductors of the length or lengths of tape cable and/or of the branch length or lengths of tape cable are electrically connected to insulated terminal leads.

    摘要： AN ELECTRIC COIL IN WHICH THE TURNS OF THE CONDUCTOR ARE WOUND IN MULTIPLES, RATHER THAN IN SINGLE STRANDS. THE CONDUCTOR IS PRINTED OR OTHERWISE PROVIDED ON A WEB OF INSULATING MATERIAL. THE CONDUCTOR IS RANGED IN A SPIRAL PATTERN AROUND A CENTRAL OPENING IN THE WEB. THE WEB ON OPPOSITE SIDES OF THE OPENING IS WOUND IN OPPOSITE DIRECTIONS SO THAT THE FLUX PRODUCED BY CURRENT IN THE CONDUC-

    TOR IS ADDITIVE WHEN THE WINDINGS HAVE A COMMON CENTRAL AXIS.
