Title: Improvements in or relating to correspondence systems

Abstract: 1,085,451. Pulse frequency discriminators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Aug. 19, 1966 [Oct. 6, 1965], No. 42394/65. Heading H3A. In a system for synchronizing two pulse trains each pulse train is applied to the " set " input of a respective bi-stable circuit A, B, and the outputs of each bi-stable circuit is coupled via an AND gate 18 to the " reset " inputs of both bi-stable circuits. When the system is applied to synchronizing the field scans of master and slave television signals odd (or even) fields of the slave may be locked to the corresponding fields of the master when ganged switches 10, 30, 50 are in position 1 or the slave signal may be merely locked to the nearest field (whether odd or even) when the switches are in position 2. With the switches in position 1, if an odd field synchronizing pulse arrives on line A before one on line B bi-stable circuit A will switch to produce an output on line X. When a pulse arrives on line B, if it is an odd field, bi-stable circuit B switches and the AND gate 18 is opened to apply " reset " pulses to both bistable circuits. No output is thus produced on line Y since bi-stable circuit B only operates momentarily. If the B pulse is an even one, it is fed via switch 50 and OR gate 21 to reset bistable circuit A. The next odd B pulse will then set bi-stable circuit B to produce an output on line Y and the following A pulse will set A to open AND gate 18 and reset both bi-stable circuits. In this case an output is only produced on line Y. Thus outputs are produced on either line X or Y depending on the phase difference between the two pulse trains. A variable amplitude control signal may be derived by feeding the two signals to gate pulses into a diode pump circuit, Fig. 4 (not shown) to charge a capacitor either positively or negatively depending on whether the gating signal is on the X or Y line. With the switches in the position 2, the slave is synchronized to the nearest pulse whether odd or even and the pulse fed to the OR circuit is derived by delaying the A pulses for half a field period.

An electrical socket outlet comprises a cover plate 22 pivotally mounted on an axis perpendicular to the plane of the front surface of the socket outlet and biased to the closed position to cover the outlet sockets. Two annular grooves encircling the outlet sockets 3 receive annular sealing rings 9, 10, and an annular groove 11 is formed concentric with and of a diameter intermediate the other two grooves, to give protection against the ingress of liquids.
