Title: Improvements in or relating to aircraft altimeters
IPC: G01S15/93
Filed: 1958-02-26
Abstract: 907,554. Echo sounding. REUMERMAN, T., and HELMIG, W. H. T. Feb. 24, 1959 [Feb. 26, 1958], No. 6269/58. Class 40 (7). In an altimeter emitting a modulated radiation and determining height by a determination of the time interval between the emitted signals and received echo signals, the repetition frequency of the modulation pattern is caused to vary in dependence on the height. Fig. 1 shows an acoustic (or supersonic) embodiment in which an emitter SE is fed with short duration pulses from generator SG. At the same time, as a pulse is transmitted a series of flip-flop circuits F11, F12, F13, &c. is triggered to cause each circuit to change to its unstable state. The circuits are graded so that after a given time F11 returns to its original state, followed in sequence by F12, F13, and so on. Each flipflop circuit has an associated gate circuit P11, P12, P13, &c. which it tends to open, when triggered, by the connection over lines such as 24. However, each triggered circuit also inhibits the opening of any following gate circuit by applying a suitable potential to the line system 25; the gates are thus opened one at a time in sequence, P11 being opened first, P12 opening between the times when F1 and F12 return to their original states, and so on. Returning echo pulses are received at R, rectified at G2 and applied to line 26. The echo pulse on line 26 passes through whichever gate circuit is open to reverse one of control circuits F21, F22, F23 ... and light the appropriate indicator lamp L. The control circuits are interconnected so that operation of one automatically resets any previously operated member of the series. The output of G2 is also fed through delay means D1 to reset all the flip-flop circuits and through further delay means D2 to trigger the generator SG and initiate a fresh transmitter pulse. In the absence of a trigger signal from D2 the generator provides pulses at time intervals corresponding to a height greater than the maximum range of the system.

IPC: H01P5/10
Filed: 1949-03-09
Abstract: 673,658. Aerial coupling arrangements. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 9, 1950 [March 9, 1940], No. 6365/49. Class 40 (v). In an electrical circuit arrangement including a feeder comprising an unscreened pair of parallel conductors connected at one end to a balanced device and at its other end to an unbalanced device, the conductors of the feeder are coiled together adjacent their point of connection with the unbalanced device in such a manner that balanced potentials at the balanced device are converted into unbalanced potentials at said point or unbalanced potentials at said point are converted into balanced potentials at the end of the coiled feeder remote from said point. As shown, a balanced device 1 which may be a dipole aerial is coupled to an unbalanced device 2, for example a radio receiver, via conductors 3 and 4, the ends adjacent device 2 being coiled together to provide a pair of coupled inductances, and optimum energy transfer is obtained if the electrical length of the coiled portion of each conductor is equivalent to an odd number of quarterwavelengths at the transmitted frequency. In some cases improved results may be obtained by spacing the coiled parts from the unbalanced device by a length of uncoiled conductor a quarter-wavelength long. In Fig. 2 (not shown) unbalanced potentials at an unbalanced device are converted into balanced potentials for transmission along an uncoiled portion of line and then converted to unbalanced potentials for feeding a further unbalanced device. Speci. fications 493,758 and 670,340 are referred to.

Title: Improvements in or relating to two-tone colour effects in synthetic fibre fabrics
Inventor: HAWORTH DEREK
IPC: D03D15/00
Filed: 1963-02-21
Abstract: Two-tone colour effects are produced in piece-dyed nylon or other synthetic fabrics by employing fibres or filaments of two varieties differing both in cross-sectional shape and delustrant content; they may also differ in dye affinity and molecular orientation.  The two varieties may constitute separate yarns to produce two tones disposed in a pattern, or both may be included in some or all the yarns.  The yarns may be of staple fibre or continuous filament, or some of each type; or yarns containing both fibres and filaments, e.g. plied or core-spun, may be used. The fabric may be woven or knitted, or the invention may be applied to the pile of a tufted fabric.  In the example, a tufted carpet fabric has pile of bulked continuous filament nylon 66; alternate tufting needles are supplied with yarn of quarter-dull trilobal filaments, and the intervening needles with yarns of bright elliptical or circular filaments (which give a darker tone); patterns may be produced by increasing the height of one kind of pile where its tone is required to predominate. Specification 854,335 is referred to.
