Electrical signal feed means are connected to the open end of the cavity at either one point or at a plurality of points which are equally spaced around the periphery. The invention also includes an aerial arrangement of a coaxial cavity which is open at one end and closed at the other, and which is fed with an electrical signal at the open end by means connected to a plurality of points which are equally spaced around the periphery. As described, a missile 12, Fig. 1, has a metallic cylindrical body 14, which is excited as an asymmetric wide band dipole by means of an annular slot element 10, located near the nose portion 15. Said element 10 comprises a conductive ring 16, Fig. 2, which is uniformly spaced from the body 14 by insulating material 18 (e.g. P.T.F.E.), and which at its forward end is fixed to, and is closed by a conductive ring member 22. Said member 22 is secured to the body 14 by screws 23, and is of substantially triangular cross-section to reduce air drag. The annular cavity so formed has a depth equivalent to a quarter wavelength at the operating carrier frequency, and it is excited at a plurality (e.g. fourteen) of equi-spaced points around its perimeter by means of coaxial lines, such as 30, 32, which are fed from a signal source 25 by a power divider 28. The spacing between a pair of feed points may be approximately one wavelength at the said frequency. As is shown in respect of the line 30, a coaxial jack 44 is provided at each feed point, the outer member 52 thereof being mounted inside the body 14, and the inner member 50 thereof being extended to the ring 16. At the end of the outer conductor 35 of the line 30 a ring 40 is soldered on, and this is clamped to the member 52 by means of a gland nut 42. The end of the inner conductor 34 of the line 30 has a sleeve 45 which receives the inner member 50 of the jack 44. The radiation pattern obtainable approximates to isotropic, apart from deep nulls fore and aft (Fig. 4, not shown).

Title: Improvements in or relating to the production of anhydrous metal chlorides
IPC: C01G1/06
Filed: 1944-01-14
Abstract: 571,201. Ferric and chromic chlorides. McCONNELL, G, COOKE, W. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 14, 1944, No. 729. [Class 1 (iii)] Anhydrous ferric and chromic chlorides are obtained by causing chlorine to react with ferrochrome in a fused salt bath, composed of one or more alkaline earth metal halides. The reaction vessel may be charged with a mixture of equal weights of calcium and barium chlorides and heated to fuse the mixture, and to maintain a temperature between 750‹ and 900‹C. Dry chlorine is then passed into the melt to remove traces of moisture, after which the ferrochrome, which may be in a relatively coarse condition, is introduced gradually. The reaction is exothermic and the temperature is maintained between 800‹ and 1,000‹C. Excess chlorine must always be present to ensure complete conversion of the metals to the higher chlorides. Ferric chloride is vaporised and condensed, while most of the chromic chloride remains in the upper part of the reaction vessel, from which it can be removed when cool; the chromic chloride remaining in the melt is recovered as such by the aqueous dissolution of the alkaline earth metal chlorides. Higher temperatures may be used whereby both ferric and chromic chlorides are vaporised and separated from each other by fractional condensation; whilst at lower temperatures the chromic chloride may be wholly retained in the melt. An example is given.

Abstract: 137,593. Moore, H. H. Jan. 13, 1919. W a t c h movements; driving- m e c h a n i s m , mainspring.-The wheelwork is such that the first or or barrel arbor 24 and the third arbor (carrying the hands 15) are central to the case 10. The barrel 23 is at the back of the framework 12, and the mainspring 22 drives the arbor, winding being effected by turning the barrel. KeyLess mechanism.-The barrel 23 to be turned to wind up the spring 22 is geared to a wheel 31 loose on the arbor 24, through a lateral arbor 34. Through another lateral arbor 28, the loose wheel, which is under a click, gears with mitre-wheels 29, 39 between the plates 12. The inner mitre 39 is integral with a nut 40 on a worm 44 of rapid pitch, which is also a sleeve on a radial stem 45. The nut is mounted in a bridge 42 between the frame plates 12, and the stem bears an inner head 45', a wheel 61, and a collar 59. A conically coiled spring strip 65 enclosing the nut and worm from the bearing-bridge 42 holds the wheel 61 on the stem against the hollow pendant 47, and a spring 60 acting from the collar 59 applies outward pressure to a disk 56 which connects a cap 52 to a sleeve 54 within the pendant. The cap overlaps a thickening- collar 50 screwed on the pendant, and the inner end of the sleeve is contracted behind the collar 59. The wheel 61 on the stem is formed with a pyramidal boss 63, and the contracted inner end of the sleeve has a corresponding mouth. The motionwork is in train with the wheel 61 on the stem through a crown-wheel 17 and a small pinion 64 on the inner end of the pendant. The pendant is not attached to the band 10, but can slide inwards. Slight pressure on the cap 52 puts the pyramidal parts of the sleeve and stem into contact, so that rotation of the cap sets the hands. Pressure sufficient to shut up the enclosing-spring 65 pushes the worm 44 through the nut 40, so turning the mitre-wheels and winding up the mainspring. Possible ineffective passage of the worm by turning in the nut is prevented by giving the wheel 61 a clutch-face to engage a counterface at the end of the worm. On releasing the cap, the inner head 45<1> of the stem thrusts the worm back through the nut, the clutch members separating to let the worm turn on the stem, since the nut is held from reversal by the click which stops the winding-wheel 31.
