Abstract: Abstract of the Disclosure A signal-processing circuit comprises a first gate circuit, a chrominance signal amplifier, a hue control circuit, means for reproducing a composite color signal, an AC coupling capacitor, and a second gate circuit.  The first gate circuit receives a composite color signal consisting of chrominance signals and burst signals which are arranged alternately and then extracts the chrominance signals and burst signals from the composite color signal. The extracted chrominance signal is amplified by the chrominance signal amplifier, while the phases of the extracted burst signal is con-trolled by the hue control circuit.  The outputs of the chrominance signal amplifier and the hue control circuit are added by said reproducing means, thereby reproducing a composite color signal. The AC coupling capacitor is coupled to the output of said means. The second gate circuit extracts from the output of the AC coupling capacitor chrominance signals and burst signals.

Abstract: ABSTRACT           A quadrature transposition stage comprising first and second signal paths, each having a modulator followed by a fil-ter including a rasonant circuit and an input circuit coupling a first input of each modulator to a common inpput.  The output signal of a local oscillator is applied, with such a phase, to a second input of each modulator so that the output signal of the filter in the first signal path is in quadrature with the output signal of the filter in the second signal path and an output circuit couples the output of each filter to a common out-put.  The resonant circuit in each of the two filters is formed by an impedance and an imaginary conductance.  The imaginary conductances in the respective resonant circuits are introduced by a gyrator having a first port which terminates in the im-pedance belonging to the rasonant circuit of one filter and a second port which terminates in the impedance belonging to the rasonant circuit of the other filter.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is an interlock mechanism for a switched socket outlet having a movable switch and a socket accepting a plug having an external key.  The mechanism comprises a unitary, substantially L-shaped latch member having two, spaced apart key-engaging projections extending from one end of the member.  The latch member is mounted for pivotal movement in one direction from a first position in which the outermost projection allows insertion of the plug, to a second position in which the plug key abuts the innermost projection to pivot the latch member and the outermost projection in the one direction.  In the second position the outermost projection locks the key to obstruct the withdrawal of the plug.  The latch member is lockable in said second position by a locking means which is displaceable to a latch member locking position by operation of the switch to an "on" state.  The latch member is arranged so that in the first position it obstructs displacement of the locking means to the locking position.          Thus, the switch can only be turned on after the plug is inserted into the socket.
