In a cathode-ray tube comprising two electron guns 6, 7 disposed parallel to each other and each associated with a pair of deflector plates 8, 9 for deflecting the respective electron beam in directions parallel to that in which the guns are spaced apart; at least one of these pairs of deflector plates is asymmetric with respect to the associated gun axis so as to produce a displacement or extension of the target region over which the respective beam can be deflected and thereby to increase the degree of overlap of this region with that over which the other beam can be deflected. As shown, in a display tube for comparing electrical signals, both pairs of deflector plates 8, 9, to which the signals are applied, are inclined towards the tube axis, time-base signals being applied to a pair of deflector plates 10 common to both guns. For coincidence of the two beams on the target in the absence of deflecting signals, a bias voltage is either applied to each pair of plates 8, 9, or to auxiliary deflector plates 11 provided between each gun and plates 8, 9. In the latter case, the beams enter the spaces between plates 8 or 9 substantially parallel to these plates. In an alternative arrangement, Fig. 2 (not shown), each pair of plates 8, 9 has portions extending parallel to the gun axes and portions nearer the target flaring outwardly, the inner plate of each pair being flared to a greater extent than is the outer plate. The invention may also be applied to tubes having three guns, the axes of which lie in a single plane.

[Class 37] The rate of operation of a single electrical contact member IR is changed into a quantity, e.g. a direct potential, by static electrical means, and is measured at MC1. Actuation of contact IR connects condenser GC to point IT to reduce the conductivity of valve PV and discharge condenser GC over the grid-cathode path of valve PV; the increase in anode potential is applied over neon tube NT to charge condenser C, which is connected over a smoothing circuit TDT of long time constant, to a cathode follower CFT whose output is fed over resistance CM to discharge condenser C. As. the rate of actuation of contact IR varies, e.g. increases, the charge on condenser C tends to rise, thus increasing the output of CFT to increase the rate of discharge of condenser C. Meter MC1 measures the output of CFT to indicate the rate of actuation of contact IR. Specification 629,244 is referred to.
