Title: Improvements in and relating to electric discharge apparatus
IPC: D01H3/08
Filed: 1935-10-23
Abstract: 456,031. Mercury-vapour apparatus. LEHMANN, W., 45, Trabener Strasse, Grunewald, Berlin. Oct. 23, 1935, No. 29248. Convention date, Oct. 23, 1934. Addition to 426,039. [Class 39 (i)] The inert gas introduced according to the parent Specification at a pressure of À01-À15 mm. into a discharge vessel sealed from the pump and containing a mercury cathode and filling the entire vessel or at least the parts near the anodes when the vessel is cold is displaced from the vicinity of the anodes and from the discharge path on heating of the vessel under load. The upper part of the vessel 1 is maintained cooler than the lower part by cooling and by locating the anodes 7 near the bottom of the vessel. The mercury blast from the cathode 2 displaces the inert gas into the space above the conical shield 12 with apertures or channels 13, 14 near its top and bottom for passage of gas. Guide plates may be provided to direct the gas. A shield 15 protects the channel 14 from the direct blast. Separate coolers 20, 21 are provided for the two halves of the vessel 1 and communicate with reflux condensers 22, 23. The condenser 22 is cooled more than the condenser 23 by drawing air down the chimney 26 or by arranging the condensers in separate chimneys. The cooling liquid is one such as carbon tetrachloride yielding few hydrogen ions. The condenser 22 may be continuously cooled and the condenser 23 may be cooled intermittently according to the temperature of the cooler 21. In a modified cooling arrangement, the vessel 1 is surrounded by a jacket down which air is drawn. A heavy rare gas such as argon or krypton is preferably used at such pressure that the current carrying capacity of the apparatus is the same when the apparatus is cold and the discharge is carried by the gas as when the discharge is carried by mercury vapour. The cold gas pressure and the operating vapour pressure may be À04 and À2 mm. respectively. The gas and vapour pressures are such that, when the apparatus is cold or hot, they lie above the limit at which the saturation current per division of the baffles at the lower ends of the anode shields 10 attains its maximum value as described in Specification 443,071. The Specification as open to inspection under Sect. 91 comprises also the replacement of the mercury cathode by an incandescent cathode over a mercury pool. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture of agglomerates of carbonaceous material without addition of pitch
IPC: C10L5/08
Filed: 1934-10-13
Abstract: Ores are mixed with coal or lignite treated or to be treated to form globulated coal as in the parent Specification.  Roasted blendes or siderite with or without fluxes or materials such as limestone, dolomite, fluorspar, marl, quartz, sandstone, slags, silicates, sulphates, magnesium or manganese are referred to.  The amount may comprise up to 85 per cent of the total mixture and exceeds 40 per cent if the material is carbonaceous and added before the globulation process.  The mixture is pressed hot and may be distilled to form coke or semicoke, or it is treated with solvents according to Specification 369,976 [Group XII].  In one method very meagre coal from which globules sufficient for agglomerating purposes cannot be produced is heated and added to a small quantity of rich coal globulating at a temperature somewhat lower than that of the heated coal, the mixture then being pressed.  Ores may be similarly treated. To avoid rupture of the agglomerates pieces of coal, coke, or non-combustible material of a size larger than the particles to be agglomerated may be introduced.  Specifications 357,330 and 358,181, [both in Group XII], also are referred to.

Title: Improvements in or relating to a horizontal spray dryer
Inventor: KOHLINS WILLIAM DAVID
IPC: A23F5/34
Filed: 1960-08-26
Abstract: <PICT:0910830/III/1> <PICT:0910830/III/2> In a spray evaporator comprising a horizontal chamber 9 and a horizontal duct 51 for introducing a primary stream of hot drying gas into the chamber, the spray-nozzle 66 for the liquid-to-be-evaporated being at the outlet of duct 51, a secondary stream of hot drying gas, having a lower velocity than the primary stream, is introduced into the chamber through a large opening in the end-wall 10, below duct 51, this large opening having a vertical perforated screen 14 disposed across it in order to impart streamline flow to the secondary stream of drying gas.  The apparatus may be employed to produce dry coffee from solutions thereof.  Chamber 9 has a double-shell; and ambient air, supplied by blower 21, is passed through passages 16 for cooling purposes.  The air discharged from the double-shell is drawn, together with fresh air, into blower 36; and the air is then passed through a directfired combustion heater 42, the burners of which are supplied with burning-gas through line 44. Hot gas from the heater flows into duct 51, and is also supplied by ducts 56 and 61 into conicalhead 50, which is divided by partitions 55 into two separate chambers 53 and 54.  The temperature of the gas supplied to chambers 53 and 54 can be regulated by air drawn in through ducts 59 and 63. The liquid-droplets from nozzle 66 are rapidly dried and inflated into hollow solid spheres which then descend, under gravity, through the secondary stream of drying gas whereby a slower drying action takes place and dense walls are imparted to the spheres.  The third stream of drying gas, which is introduced into chamber 9 via chamber 54, isolates the roof of the chamber 9 from the liquid-spray.  On reaching the bottom of the chamber 9 the spheres are moved to the discharge spout 31 by screw-conveyer 29.  The moist gas passes from the chamber through duct 71, and is then withdrawn through separator 73 and a centrifugal separator 78 by an exhaust blower (not shown). This blower together with blowers 36 and 21 are cumulative in moving air through the apparatus and can be adjusted to provide any desired sub-atmospheric pressure within the drying chamber.  Rotary sweep 88, which has perforated arms, is supplied with cool air through conduit 101 ; and this air is discharged in streams against the inner face of conical-end 11, thereby preventing the accumulation of solids thereon.

Abstract: 630,873. Aerials. STANDARD TELEPHONES & CABLES, Ltd. Oct. 4, 1946, No. 29655. Convention date, June 20, 1945. [Class 40 (vii)] In a slot aerial comprising a conducting surface containing an aperture, the perimeter of which bears a given relationship to the operating wavelength and to opposed edge portions of which energy transfer means are coupled, the operative portion of the surface is extended from the aperture by predetermined amounts to limit the establishment of points of current maxima to a given number. As shown in Fig. 1 in a slot aerial comprised of a conductive sheet 1 containing an aperture 2 provided with energy transfer (i.e. feeder) coupling points 2a, 2b, the number of zones of maximum current such as 6, 7, 8, 9, which are necessary to produce a required radiation characteristic can be selectively retained by giving a suitable configuration to the sheet 1. In one embodiment (Fig. 2) the aerial comprises a flat circular radiating surface 12, preferably formed as a disc of diameter -, and provided with a slot in the form of a 2 symmetrical cross, the perimeter of which is made equal to the wavelength #, terminal means 14, 15 serving to connect the aerial to an energy supply source. For aerodynamic reasons, when. the aerial is formed in the fuselage of an aircraft, the slot may be filled with insulating material and if desired the surface 12 may be curved or dished (Fig. 4, not shown). In another embodiment, Fig. 5 (not shown), a rectangular slot having a perimeter of length # is formed in a square conducting sheet of side 3# - and the feeder connection means are provided 4 on opposite edge portions of the slot. With this latter arrangement a pear-shaped radiation characteristic may be obtained by providing a reflector at the rear of and parallel to the conducting sheet (Fig. 6, not shown). Fig. 7 shows an arrangement simulating a dipole in which the conducting surface has an approximately figure-eight shape containing two current maxima points 30 and 31. In the arrangement of Figs. 8 and 9 two aerials 32 and 33 are disposed flush with a surface 34 (e.g. aircraft fuselage), the spaces 41, 42 being preferably filled in or forming part of an insulation annularly surrounding the aerials. The aerials are backed by reflecting members 35, 36 spaced A therefrom by - and the distance between the 4 aerials 32, 33 may vary in accordance with the desired pattern. An aerial arrangement employing a curved conducting sheet which is curved to conform with the surface of a cylinder (e.g. smokestack) is described with reference to Fig. 10 (not shown). If desired a plurality of such aerials may be arranged to form an array. Specification 591,053. is referred to.

Title: Improvements in tidal-water-power plants
IPC: F03B13/26
Filed: 1922-10-31
Abstract: 188,330. Huguenin, A. Nov. 1, 1921, [Convention date]. Addition to 171,346. Tidal energy, utilizing.-In the tidal-power plant described in the parent Specification the asynchronous generator of each unit is synchronized during continuous running and is only asynchronous during the periods in which an alteration of speed is effected. In order to obtain a current of constant voltage and periodicity in spite of variation in speed due to variation of the head such variation may be counteracted during working either by an alteration of the electric connections, for example by changing the connection of the poles, or the variation in effective head may be counteracted by mechanical gearing. In order to avoid the use of synchronous condensers the asynchronous generator is synchronized for the continuous working by means of a known device. Fig. 3 shows diagrammatically such an arrangement having a direct current exciter p, the generator comprising a stator g<1> and rotor g<2> provided with a switch o for changing from asynchronous to synchronous working; polechanging switches n of known type for altering the number of poles are included in order to maintain the frequency at lower speeds. The turbines a, b, Fig. 1, for driving the generator g through gearing c, c<1>, d, d<1>, are provided with guide-vanes e, f hinged on vertical pins so that they may be used as upward-flow, or downwardflow turbines, or may be put out of action.
