Abstract: 1,198,410. Aerials. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES (O.N.E.R.A.). 3 Dec., 1968 [15 Dec., 1967; 26 Feb., 1968], No. 57237j68. Heading H4A. A helical type aerial comprises a single conductor which is stuck to a flexible sheet of dielectric material, said sheet being wound until the edges overlap, when they are fastened together. One end of the conductor is connected to an earth plane, and coupling means are coupled to the conductor along a part thereof extending from said one end and of a length not exceeding #/100 (#= free space wavelength corresponding to the mid-band operating frequency). The total length of the said conductor is not less than 0À3# or more than 0À45#. In one embodiment, a dielectric sheet 220, Fig. 8, has adherent on its surface two end bars 224, 225, an aerial conductor 221, a connecting leg 226, and a terminal strip 227. The sheet 220 is rolled up so that a cylinder with three successive layers is obtained, giving a three-turn helix. The upper end bar 224, Fig. 10, is welded to a brass "roof" 231, and the lower end bar 225 is connected to a brass disc or base-plate 233. A coaxial feed cable is gripped in the base-plate 233 with its outer conductor in contact therewith and with its inner conductor connected to the terminal strip 227. An inductive coupling conductor is connected between the terminal strip 227 and the end bar 225, and a variable capacitor 238 is connected between the leg 226 (Fig. 8) and the end bar 225. The capacitor 238 is adjusted through an aperture 241, after which a suitable potting material 242 is injected. In another embodiment, a number of sloping parallel conductive strips, each corresponding to one turn of a helix, are disposed upon a rectangular sheet of dielectric material, which is then rolled so that its edges just overlap (Figs. 11a 11b, 12, not shown). In another embodiment, a conical helical aerial is described (Figs. 13, 14, not shown), and printed circuit techniques may be used in its construction. It is stated that such helical aerials may be disposed in restricted spaces, and that they radiate omnidirectionally about their longitudinal axes, with polarization parallel thereto.
Patent GB-573905-A (GB)
Abstract: 573,905. Ignition systems. BRITISH THOMSON-HOUSTON CO., Ltd., WILKINSON, K. J. R., WELCH, D. F., and CLOUGH, F. H. Feb. 8, 1943, No. 2088. [Class 7 (iv)] A high-frequency ignition system of the kind in which the high-tension voltage generated by a magneto or coil is used to charge a condenser which is discharged through a spark gap and distributer in series across the plug, has the high-tension lead between the distributer and the plug constructed in the form of a concentric cable embodying series distributed inductance so as to make the transit time of said lead greater than the time taken to build up current in the spark gap, thus producing increased voltage across the plug. The cable inductance may be increased by placing ferro-magnetic material within the dielectric space thereof, or, preferably, by using a helically wound central conductor. The capacity of the reservoir condenser is less than the capacity of the hightension lead between the distributer and the plug, and the surge impedance of the lead is such that the transit time thereof is greater than .05 micro-seeonds. The reservoir condenser may be constituted by a capacitance/ inductance network. An example of the constants for the high-tension lead and the network is given in the Specification. Specification 235,351, [Class 7 (iv)], is referred to.

Title: Method and apparatus for measuring the turbidity of fluids
IPC: G01N21/49
Filed: 1973-12-21
Abstract: 1414038 Measuring turbidity photoelectrically OKI ELECTRIC INDUSTRY CO Ltd and JAPAN SOC FOR THE PROMOTION OF MACHINE INDUSTRY 21 Dec 1973 [28 Dec 1972] 59374/73 Heading G1A The turbidity of a fluid is measured by dividing a laser beam into two parallel rays, interrupting these rays alternately and cyclically, projecting them at different angles into the fluid in such a way that one ray passes directly through and the other ray is scattered by contaminent in the fluid, and both the directly transmitted and scattered radiation is received by a single detector to produce alternate pulses which are separated and compared to determine the turbidity. As shown, Fig. 3, the beam from a laser 15 is split into two parallel rays which are interrupted alternately by a rotating apertured disc 21. One ray is reflected by a mirror 19 and passes directly through the test fluid 14 and then via a mirror 26 to a detector 23b. The other ray is directed into the fluid by a mirror 18 and some of the radiation scattered by particles in the fluid is received by a lens 25 and directed to detector 23b. The output of the detector is amplified and the pulses separated into two channels by a gate circuit 27 operated by synchronizing pulses produced by a transducer viewing the rotating disc 21. The amplitudes of the pulses are stored in memory circuits 28 and 29 coupled to a ratio circuit 9 the output of which is displayed on meter 10 as a measure of the turbidity. The directly transmitted and the scattered beams enter and leave the fluid at the same points of input and output windows 3 and 4 and are therefore equally affected by transmission through contamination on these windows. A plate (33) having suitably positioned apertures is mounted inside the fluid chamber adjacent to input window 3 to block radiation scattered by contamination on the inside face of window 3, Fig. 5 (not shown).
