Abstract: 1,145,507. Aerials. RAYTHEON CO. 29 July, 1966 [2 Aug., 1965], No. 34134/66. Heading H4A. An aerial comprises a dipole fed by a two conductor quarter-wave transmission line, the arrangement being such that the two sections of the dipole are located in different parallel planes, with a spacer separating them and also the two conductors of the transmission line. As described, a plastics disc 50 has printed or otherwise deposited on its upper face the sections 18, 22, 26 of three dipoles 10, 12, 14 and on its lower face their other sections 16, 20, 24. The dipoles are disposed symmetrically around the periphery of the disc 50, to obtain a horizontally omni-directional radiation pattern, and they are joined to central rings 34, 58 by means of quarter-wave transmission lines 29, 31, 33 comprising upper conductors 28, 30, 32 and lower conductors 52, 54, 56. Other quarterwave transmission lines 39, 41, 43, which extend, from the rings 34, 58, between the lines 29, 31, 33 and are short-circuited by wires 45, 47, 49 passing through the disc 50, thus providing symmetrical direct-current return paths, are stated to improve the radiation pattern of the aerial. A coaxial cable has its inner conductor passing through a hole 36 in the disc and connected to the upper ring 34, its outer conductor being connected to the lower ring 58.

Abstract: 605,491. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34574. Convention date, June 23, 1943. [Class 97 (i)] In range-finders of the type in which images of an adjustment indicating mark or marks in one comparison plane of the finder are formed in or adjacent to the other comparison plane by the optical system of the finder, the marks, which may comprise virtual images, are spaced apart horizontally in the one plane and their images are combined in the other plane by a reflecting system including a roof reflector, coincidence of the resulting reflected images indicating correct adjustment of the rangefinder. In the stereoscopic finder shown in Fig. 1, the marks 45 in comparison plane 34 are illuminated by lamp 43 and images thereof are formed adjacent the other plane 33 by objective 32, optical square 31, prisms 46, 47, and the other optical system. A prism 48 receives the beams one image being reflected at the full reflecting surface 49, Fig. 3, by the semitransparent surface 50 and the other passing through surface 50 and being reflected by a reflecting surface 51. The two reflected images are observed in eyepiece 53, Fig. 1, coincidence indicating correct adjustment which may be effected by light deviator' 55. A coincidence finder, Fig. 4, has prisms 67, 68 bringing the two images into coincidence in a comparison plane 69. This plane contains an adjustment mark illuminated by lamp 72 and prism 73, the light being divided into two beams by a prism 74, or, alternatively, two such prisms. After passing through the range-finder system, the beams reach a prism 77, one beam being reflected by the faces 82, 85 thereof, Fig. 5, to enter the eyepiece and the other passing a semi-reflecting surface 83 and being reflected from a reflecting surface 84 back to the surface 83 and thence to the eyepiece via surface 85. The prism 77 may be extended to ensure that the mark images are in the same plane as the object images. Various other optical systems of prisms or mirrors are described, producing two adjustment mark beams from a single mark and for combining them in the eyepiece or in an auxiliary eyepiece coincidence of the images indicating the correct adjustment of the instrument. Specification 605,490 is referred to.

Abstract: In the production of carbon black by the injection of coal tar oil, combustible gas and air into a carbon black furnace, the effluent gas is freed from carbon black, fortified with the vapour of a hydrocarbon having a b.p. of 30-280 DEG  C., e.g. crude benzine, and recycled to the process as combustible gas; 20-100 kg. of crude benzine per 100 cu. m. of purified exhaust gas may be employed.  The carbon black may be removed from the effluent by filtration, centrifugation or electrostatic precipitation. The effluent may be then washed with water and passed through water separators and filter candles.  As shown, oil from an inlet 2, hot or cold air from an inlet 3, and combustible gas from an inlet 19 are injected under <PICT:0963526/C1/1> pressure into a furnace 1. The resulting effluent passes to a cooling and carbon-separation section 5, carbon black being drawn off through an outlet 6 and effluent gas passing to a water-washing tower 8.
