Title: "improvements in or relating to radar systems"
IPC: G01S7/02
Filed: 1946-05-06
Abstract: 616,711. Radiolocation; aerial coupling arrangements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 6, 1946, No. 13732. Convention date, Sept. 9, 1944. [Classes 40 (v) and 40 (vii)] In a radar system, the transmitter sends' out a continuous wave having its direction of polarization continuously varying and distance is determined from a comparison of the angle of polarization of the reflected wave with that of the wave at that instant being transmitted. In one system, Fig. 5, transmitting and receiving reflectors 12, 22, which are so mounted that their axes of directivity remain parallel during scanning movements, are associated with aerials, the planes of polarization of which are continuously rotated at slightly different rates by synchronous motors M, M<1> and gear boxes 81, 82. A c.w. transmitter 10 feeds one aerial while the other aerial feeds a receiver 24. Tone wheels 85, 86 generate frequencies fr, ft proportional to the speeds of rotation of the planes of polarization so that the difference frequency fr-ft derived from the mixer 87 depends upon the difference in rotational speeds. The frequency fr-ft, is passed through a phase shifter 88 to synchronize a sawtooth generator 90 which provides the horizontal sweep deflection voltage for the oscilloscope 110, so that at any instant the position along the trace is proportional to the angle of deviation between the planes of polarization of the aerials. The signal output from receiver 24 is fed to produce vertical deflection of the trace on the oscilloscope, the position along the trace of the dip in the pattern corresponding to the null in reception occurring when the planes of polarization of the transmitting and receiving aerials are at 90 degrees to one another, indicating the range of the reflecting object producing the signals. The rotating aerials, Figs. 2, 3 each comprise a, disc-shaped radiator 40, capable of resonating about a diameter and energized by coupling between the teeth 41 and the teeth 44 on the surrounding structure which constitutes a resonant cavity fed by transmission lines TL, TL1,TL2. The numbers of teeth on disc and housing are dissimilar so that the points of close coupling CC and loose coupling LC will rotate around the disc at a greater rate than the disc itself is rotated by the motor M. The plane of polarization, which passes through point CC and the centre of the disc will thus also rotate at the higher rate. In a simplified embodiment of the invention, Fig. 1 (not shown), the aerials are dipoles rotated directly by synchronous motors with provision for varying the phase displacement between the motor feeds to observe a null in the received signals.

Title: Improvements relating to automatic telephone systems
IPC: H04M3/14
Filed: 1920-05-20
Abstract: 168,134. Siemens Bros. & Co., Ltd., and Christian, D. A. May 20, 1920. Automatic exchange systems.-If a selector is not operated by a subscriber within a given timeinterval after it has been taken into use bv a pre-selector, its test lead and the test leads of other disengaged selectors accessible from the same pre-selector are disconnected from 'battery. The pre-selector moves on to a position in which an alarm circuit may be closed and the line relay bridged across the calling line. When a subscriber removes his receiver, or if a fault occurs on the line, the pre-selector PS acts in the usual way to find an idle selector GS, the relays T, A, V, Q being energized. If the contact K<1> is not opened by the operation of the selector before a contact 1 is closed by a cam 5 of a time switch C, the relay S operates and prepares a circuit for a relay Z which is energized when the switch C closes contact 2, provided that the contact K<1> remains closed. The relay Z disconnects battery from the test lead of the selector GS and of the other disengaged selectors in the group, whereupon the relay T causes the magnet D to rotate the wipers a, b, c until they reach the last set of terminals, thereby connecting the line relay R to the calling line and closing the circuit of an alarm relay P. The switch C and relays Q, S, Z are common to a group of selectors.

Abstract: 1381996 Tuning piezoelectric resonators STATEK CORP 22 March 1973 [22 March 1972] 13900/73 Heading H1E A tuning-fork microresonator is mounted in a sealed container having a transparent portion which allows passage of a laser beam for selective removal of loading material on the tines of the resonator, whereby to tune the resonator. The resonator 16, Fig. 1, is attached by mounting block 17 to a glass plate 18 forming, with cover 37, a hermetic container. Thick-film coatings 20, e.g. of gold, may be selectively removed by a laser situated outside the sealed container. Each coating may comprise a thick portion and a thin portion respectively for coarse and fine tuning. The laser may be controlled by the output of an oscillatory circuit which includes the resonator, whereby tuning is accomplished automatically. The laser may scan the coatings. The resonator may be made of electrostrictive or piezoelectric material; e.g. a quartz resonator may have tines parallel to the Y-axis of a plate cut at an angle of rotation from 45 to 70 degrees about the Y-axis, with up to 8¢ degrees rotation about the X<SP>1</SP> axis. Electrodes 22, 25 are arranged, as shown, on the upper surface of the resonator whilst the under surface bears a single electrode 29, Fig. 2, covering both the tines except in the area occupied by the loading material. The glass plate 18 also supports a microcircuit 35, leads 31, 32, 33 and terminal plates 34 situated outside the container. For extra fine tuning, the resonator is associated with a capacitor having electrodes 76, 77 on the inner surface of the glass plate and electrode segments 78, 79 on the outer surface. The capacitance is determined by the number of segments interconnected by a shortcircuiting member in the form of a piece of adhesive tape 80. A number of sealed units are simultaneously prepared by mounting resonators, microcircuits &c. on identical segments of a large glass plate subdivided by a grid of grooves. Each segment is provided with its own cover and each resonator is individually tuned. The adhesive 38 used to secure the covers is cured and the assembly heated in a vacuum or inert atmosphere to melt alloy plugs 39 which seal apertures 40 in the covers.
