Filed: 1972-09-27
Abstract: 1393160 Aerials M E TIURI 27 Sept 1972 [1 Oct 1971] 44575/72 Heading H4A A travelling wave aerial comprises a chain 1, Figs. 1, 2, of four sided links 3 connected together by parts 6, a ground plane 2 thereunder, and a feed cable with two conductors which are respectively connected to one end 7 of the chain 1, and to the ground plane 2. The connection parts 6 extend between the centres of adjacent long sides 4 of the links 3 and, as seen in plan view, are parallel to the short sides 5 thereof. The aerial is operable over a wide band of frequencies with low side lobes, the main beam having a elevation angle # which is frequency dependent. The far end 7 of the chain 1 may be left open, when radiation absorbing material may be installed thereunder, or it may be connected to the ground plane 2 through a suitable load impedance. It is also possible to feed the aerial at both ends, at different frequencies. The cross-sectional dimensions of the links and of the connection parts may be made to differ, so as to improve matching, for example, so that the characteristic impedance of the transmission line formed by a connection part 6 and the ground plane 2 is half the characteristic impedance of the transmission line formed by each half of a link 3 and the ground plane 2. The lengths of the sides 4 may be #, the lengths of the sides 5 and of the connection parts 6 may be #/4 to 3#/4, and the chain 1 may be #/10 above the ground plane 2, where # is the wavelength at the mean operating frequency. Instead of being rectangular, the links may be parallelograms, with their longer sides inclined to the connection parts (Fig. 3, not shown). The chain or the ground plane, or both, may be curved. The distance between the chain and the ground plane may increase from the feed end continuously or in steps, for example, from #/20 to 3#/10. The lengths of the sides of the links, and of the connection parts, may increase continuously along the chain, for example, by 2% from link to link, or two different sizes of connection part and link may be used alternately (Figs. 5, 6, not shown). In other arrangements, two such chains may be disposed side-by-side above a common ground plane, with adjacent shorter sides of links connected together, either at the ends thereof or along their entire lengths. The two chains are paralleled at their feed ends to a common source (Figs. 7, 8, not shown). An arrangement which provides elliptically or circularly polarized radiation comprises two angularly disposed aerials using parallelogramshaped links and having mirror-image symmetry about an axis 14, Fig. 9. A common feed point 9 is directly connected to one aerial, and is connected through a phase shift element 13 to the other aerial.

Title: Tone detectors
IPC: H04Q1/448
Filed: 1973-09-11
Abstract: 1482629 Tone detector TREND COMMUNICATIONS Ltd and L F LIND 23 Dec 1974 [2 Oct 1973] 45877/73 Heading G4H A tone detector comprises means for generating a tone whose frequency is the same as that to be detected and which is not 90 degrees out of phase therewith; this signal is combined with an input signal and the resulting signal is integrated for a predetermined time period related to the frequency to be detected, the integrated signal then being analysed to determine whether the input signal contained the required frequency. In the embodiment of Fig. 1, two signal generators 10, 11 are used (sin w 1 t, cos w 1 t) so that one at least will not be 90 degrees out of phase with the input signal A. Each generated signal passes through a multiplier 14/15, an integrator 16/17 and a device 18/19 which determines the absolute magnitude of the integrated signal, before being fed to a combiner 20 which either selects the greater of the two values or calculates the square root of the sum of their squares. A discriminator then compares the output from 20 with two threshold levels, the lower of which exceeds the highest possible output from 20 when signal A is not the desired frequency and the upper of which is lower than the lowest output from 20 when signal A is 45 degrees out of phase with the outputs from both 10 and 11 and when A is the desired frequency. The output from 20 increases indefinitely when A is the desired frequency, but can be made very small when the desired frequency is absent by suitable choice of the period of integration. When the output from 20 is higher (lower) then the upper (lower) threshold the tone is indicated as being present (absent), and when it falls between them a further indication is given (e.g. lighting a warning indicator, or supplyng A for a second analysis). The apparatus may be used to indicate the presence of any one of a "linear array" of tones (each spaced from the next adjacent tones by an equal frequency). In the embodiment of Fig. 6 the input signal A is amplified and clipped, then combined with a pulse signal B in an EXOR gate 30, the output from which is fed via a second gate 31 to a counter 32 which counts clock pulses and acts as an absolute-magnitude integrator. A flip-flop 39 and a monostable 41 are provided to rectify the count when this goes below 0 (a "borrow" output on a count of 99 from the tens section 34 clocks 39 when 41 is caused to reset the counter to a count of one), flip-flop 39 controlling gate 31 so as to direct the clock pulses to an "up" or "down" NAND gate 37 or 38 respectively. Signal B may be obtained from a high frequency source via a counter acting as a frequency divider. The counting pulse rate may be given a sine "taper.'.

Title: Arrangement for evaluating the duration of a signal
IPC: H04B11/00
Filed: 1975-11-06
Abstract: 1524038 Remote control LICENTIA PATENT VERWALTUNGS GmbH 6 Nov 1975 [27 Nov 1974] 46023/75 Heading G4H In a circuit arrangement for evaluating the duration of a received signal, pulses are counted while the signal endures, the feed of pulses to the counter being stopped and the count cancelled if the duration exceeds a predetermined maximum value. As disclosed, an ultrasonic (or radio) control signal consists of a duration-significant portion of a first frequency followed by a portion of a second frequency. The two portions, after conversion to electric form, are separated on to respective leads, the pulses of the first portion being gated to a first counter, recognition of a count of 4800 at the high order end of the counter causing the signals from a lower stage of the counter to be gated to the count-up input of a reversible counter. Arrival of the second portion of the control signal blocks the input to the first counter and causes clock pulses to decrement the reversible counter to zero relatively quickly, the clock pulses actually used in this decrementing also going to a control circuit to select the channel of a TV set. If an excessively high count is reached in the first counter (indicating interference), the gate at the input to the first counter is disabled and the reversible counter is reset. Other control functions, e.g. involving level changing, can be controlled by count ranges starting at values other than the 4800 value above, but otherwise in a similar way. Control of a radio is also mentioned.
