Title: Improvements in or relating to aerials operating simultaneously on two different frequency bands
IPC: H01Q5/45
Filed: 1955-11-16
Abstract: 782,042. Aerials. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 16, 1955 [Nov. 18, 1954], No. 32801/55. Class 40 (7). An aerial system for the radiation or reception to or from the same direction of energy on two frequencies comprises two different primary elements for the respective frequencies mounted on opposite sides of a device which acts as a mirror for energy of the lower frequency and as a lens for energy of the higher frequency. The device may be constructed in the form of a number of perforated plates as described in Specification 689,408. These plates may be substantially parallel and paraboloidal with a common axis z. The plate nearest the element F2 acts as a mirror for waves of one of the frequencies and has feed F2 at the mirror focus. All the plates are provided with holes in a square lattice pattern, the sides of the lattice being smaller than the shortest wavelength to be transmitted. They act as a lens in respect of the higher frequency energy and a second primary element F1 is placed at the lens focus. The primary elements may be radiating horns or dipoles and the device may be so constructed that the primary element F2 can be off-set out of the path of the beam (Fig. 2, not shown). In another modification the plates are parabolic and doublets excited from a coaxial line are arranged along the focal axis to form the element F2 (Fig. 4, not shown). For manufacturing convenience the shaped plates of the device may be made up from a plurality of plane elements. The aerial system may be used in an object detection system in which it is desired to radiate search and interrogation signals of differing frequencies at the same time. The energy radiated may be amplitude, frequency, or pulse modulated.

Title: Improvements in or relating to the manufacture of nickel carbonyl
IPC: C01G53/02
Filed: 1933-11-28
Abstract: Nickel carbonyl is made by the action of carbon monoxide under pressure on nickel matte mechanically mixed without fusion with copper or iron in sufficient quantity for all the sulphur to be bound as cuprous or iron sulphide.  The copper or iron may be added as metals, as oxides, in which case the mixture is reduced before the carbon monoxide treatment, as calcined, or calcined and reduced mattes, or as residues from the treatment.  In the last case, the same copper or iron can be used repeatedly in cyclic manner until a sufficient quantity of precious metals has accumulated which is then recovered.  Moreover, only some 90 per cent of the nickel need be extracted since the residue, preferably after calcination and reduction, is used again.  According to examples: (1) A mixture of ground nickel sulphide matte and precipitated copper is treated with CO at 200 atm. and a maximum temperature of 210 DEG  C.  The residue is calcined, reduced at 360 DEG  C. with hydrogen, and mixed with more matte.  (2) A mixture similar to that of example (1) is briquetted and treated with CO at 175 atm. and 180--200 DEG  C.  The residue is treated as in (1). (3) Sulphides of nickel containing a little copper are mixed with iron filings and treated with CO at 250 atmos. and 250 DEG  C.  The residue is calcined, reduced in hydrogen at 400 DEG  C. and re-used. The nickel carbonyl is obtained mixed with a little iron carbonyl which can be separated, or the amount of the latter can be reduced by heating the mixture of matte and iron filings, say at 250 DEG  C. and 250 atmos., for 1--3 hrs. before treating with CO.  (4) A mixture of uncalcined, and calcined and reduced copper-nickel Bessemer matte is briquetted and treated with CO at 200 DEG  C. and 200 atmos.  The residue is calcined and re-used.  Specification 327,956, [Class 1 (ii)], is referred to.ALSO:In a process of extracting nickel from nickel mattes by the action of carbon monoxide, copper or iron sufficient to bind all the sulphur is added to the matte.  The residues, containing the precious metals in addition to the added metal, can be used again in cyclic manner until a sufficient quantity of precious metals has accumulated which is then recovered.

Abstract: 1341448 Multi-mode waveguide rotary junctions HUGHES AIRCRAFT CO 15 July 1971 [15 July 1970] 33339/71 Heading H1W A multi-channel rotary junction capable of transmitting three independent signals comprises a circular waveguide having a rotary joint and arranged to transmit energy in three modes each of which is derived from a respective input by means of a combination of hybrid junctions, and transmitted to a respective output by means of a like combination of such junctions. The arrangement thus comprises two symmetrical halves coupled by a rotary joint (not shown) and Fig. 4 shows the input half of the arrangement. Signal A is fed to the summing port (#) of a 180 degree hybrid junction 30, Fig. 3, and signals B, C to conjugate ports of a 90 degree hybrid 34 of which the two remaining conjugate ports are connected to the differencing inputs (#) of 180 degrees hybrids 30, 32. The output ports of hybrids 30, 32 are connected respectively to the differencing and summing ports of two further 180 degree hybrids 31, 33 the four output ports of which are connected respectively to 45 degree twists 36, 37, 38, 39. In Fig. 4, the 180 degree hybrids are shown as magic-T's (some folded) but the 90 degree hybrid is omitted. The output ends of the 49 degree twists 36, 37, 38, 39 are of rectangular section and are arranged symmetrically with their major axes parallel to two orthogonal diameters of the circular co-axial waveguide 47. It can be shown that input A excites a circular electric TE 01  wave in waveguide 47 whilst inputs B, C excite respectively right and left-hand circularly-polarized. TE 11  waves (see Fig. 7, not shown). The twists are matched to the circular section by four pyramidal inserts 50. The three wave modes propogate independently through the co-axial waveguide and the rotating joint to an output arrangement which is the mirror image of the Fig. 4 input arrangement. The central conductor 48 may enclose one or more coaxial transmission lines for transmission of low-power signals through the joint.
