Abstract: 667,658. Aerials. STANDARD TELEPHONES & CABLES, Ltd. April 26, 1950, No. 10274/50. Class 40 (vii). Relates to an aerial system for use at the terminal or repeater stations of a two-way radio link comprising two adjacent similarly directed aerials 1 and 4 coupled respectively to a transmitter 8 and receiver 12, in which the aerials comprise paraboloidal reflectors 2 and 5, associated with horns 3 and 6, the apertures of the reflectors and horns being substantially coplanar. According to the present invention, direct coupling between the radiator elements is reduced by a rectangular metallic screen 13 positioned in a plane perpendicularly mid-way between the aerials. One dimension of the screen extends a distance l of the order of several wavelengths in front of the aperture plane and extends in the reverse direction a distance of at least #/2 and the other dimension y extends equally on either side of a line joining the horns by an amount r equal to the radius of the reflector apertures u y=2r; suitable dimensions are given for operation at a wavelength of 6.3 cms. Alternatively the screen may be dimensioned so that coupling due to energy leakage over the edges parallel to the aerial directivity is neutralized by coupling due to energy leakage over the edge parallel to and in front of the aperture plane, the dimensions l and y being 6-10# and 3-5# respectively.

Class 40 (5) The sound channel of a television receiver comprises an H.F. stage followed by a superregenerative amplifier quenched by a voltage obtained from an oscillatory circuit shock excited by the flyback voltage of the line scanning circuit. The oscillatory circuit 15 is resonant at the fifth to tenth harmonic of the line scanning frequency and when shock excited maintains its oscillation at a sufficient level to provide the quench voltage for the superregenerative detector 19. A diode 29 provides a bias for the detector which decays slowly between line pulses and compensates for the decreasing quench oscillation amplitude. An alternative circuit, Fig. 3 (not shown), comprises a linear mode super-regenerative amplifier and a separate detector. The diode circuit is connected across a portion of the coil 15 and feeds its D.C. output to the right hand side of capacitor 28. The quench voltage may alternatively be applied to the anode of the super-regenerative amplifier. The first Provisional Specification suggests the use of a super-regenerative receiver in the vision channel, the quench oscillatory circuit being followed by frequency multipliers.

A parallel arrangement of control valves has a block 11, Fig, 1, with bores for three-position spool-valves A, B, and C, an inlet chamber 15 and an exhaust chamber 18 with limbs 19, 21 intersecting the opposite ends of each valve bore; branch passages 16, 17 leading from the inlet chamber 15 also intersect the valve bores. Each bore is also connected to an open-centre path 22-25 in the valve neutral-position shown, which connects a carry-over port 14, Fig. 2, to the chamber 15, Fig. 1. The valves are identical and each incorporates two lands 31, 32 that are hollow and intersected by radial passages 33, 34 and 35, 36, respectively; each land controls a motor port 26, 27. The exhaust chamber 18 opens into a port 13 (Fig. 2, not shown) and surmounts a further chamber 37 connected to the inlet branches 16, 17, Fig. 1, and with the exhaust chamber 18 via a spring-loaded valve 43, the stem 41 of which is hollow and contains radial ports 47 and leads to the port 13. The ports 47 co-operate with a web that divides the chamber 18 into upper and lower sections 18U, 18L. When one or more of the valves is operated so that movement of a ram connected to the ports 26, 27, is opposed by the applied load the valve 43 remains in the position shown and the ports 47 conduct the exhaust fluid to port 13. Should opposite motion of the ram result in cavitation, the supply pressure in chamber 37 falls below that in exhaust chamber 18 and the valve 43 opens and ports 47 are restricted so increasing the back-pressure in chamber 18 and causing fluid to flow through valve 43 into chamber 37 to supplement the inlet fluid. In a modification, the spool valves are arranged in series-parallel and the carry-over port is dispensed with. The chamber 37<SP>1</SP> (Fig. 5, not shown), is connected directly to the inlet chamber 15<SP>1</SP> whilst the stem 44<SP>1</SP> has two sets of radial ports 64, 65 which coact with corresponding ports 62, 63 in a sleeve 61. The stem is freely rotatable in the sleeve 61 and the ports 64 are offset relative to the ports 65 so that flow to the exhaust port 13<SP>1</SP> is never cut-off or unduly restricted.
