A binder clip for coils comprises a pair of bifurcations 14, 14a extending alongside one another and each having an open offset loop portion 17, 17a extending towards the other bifurcation, so as to overlap the loop portion thereof, thereby forming a closed loop disposed remote from the crotch portion 13 of the bifurcations, the free ends 21, 21a of the bifurcations being capable of manual manipulation to provide an entry gap in the loop and the free ends being spaced apart, in the general plane of the closed loops, to form a guideway 24 adaptable to secure a coil upon which the binder clip is about to be installed. As shown in Figs. 2 and 3, the clip is made of a length of wire which may be chromium plated and which is bent double to form the bifurcations 14, 14a. The loop portions 17, 17a are substantially semi-circular in shape and each is joined to the initial portion of each bifurcation by a right-angle bend. Beyond each loop portion the bifurcations continue at right angles to the loop portions to form the free end portions 21, 21a which are parallel to each other as shown in Fig. 2 but bent at about 40 degrees in opposite directions relative to the general plane of the clip as shown in Fig. 3. To avoid damaging the coils the end portions are formed . with smooth ball-like heads 25, 25a. After the guideway 24 has been engaged with a coil the clip is twisted clockwise to engage the loop portions 17, 17a with the coil. In a modification each bifurcation is formed separately of springy wire and their upper ends are fastened to a flat finger piece.

The invention relates to a system generally similar to that described in Specification 1,011,399 in which a signal for transmission is derived from an input pulse train: adjacent input pulses result in pulses of like polarity but pulses separated by one or more zeros result in pulses of opposite polarities separated by that number of zeros. In the present invention a pilot signal is transmitted, it being arranged that this signal is zero at the instants at which the received signal is sampled. The pilot signal is sinusoidal and of frequency equal to one quarter the input bit rate. It is added to the modulator in one of the channels in the transmitter which is generally similar to an embodiment described in the above-mentioned Specification. The receiver, too, is similar but includes filters for obtaining the upper and lower sidebands. These are mixed and the resultant signal filtered to provide a signal of twice the carrier frequency, which is halved and fed to the receiver ring demodulators, and a signal at twice the pilot frequency, which controls the generators used for sampling the demodulated signals.
