Title: Fly ash entrapment wall
IPC: F22B37/40
Filed: 1962-07-13
Abstract: In a pulverulent fuel fired slag tap furnace, the burner or burners are directed against a wall of zig-zag or undulating cross-section providing vertical troughs down which the molten slag runs. In a water tube steam generator, Figs. 1 and 2, divided into two combustion chambers 12, 14 by a zig-zag wall formed of tubes 15 encased in refractory material 24, burners 11 in each combustion chamber deliver towards the vertical troughs formed in the wall, which is maintained below the fusion temperature of the ash. A coating of slag builds up until the temperature of the outer surface rises sufficiently to allow molten slag to run down the troughs to outlet openings 26 at the bottom of the combustion chambers. The steam generator has a reheater 16 secreened by the upper ends of the tubes 15, superheaters 18, 20 and an economizer 22. Fly ash carried over is collected in a hopper 32 and returned to the combustion chamber. The burners may be directed towards the apices of the zig-zag wall. In a steam generator furnace having a single combustion chamber, Figs. 5 and 6, not shown, the rear wall has vertical troughs only opposite the burners. In a cylindrical furnace, Fig. 8, the burners 11 deliver against the troughs of a central star-section baffle.

Filed: 1963-08-31
Abstract: An area F, Fig. 3, to be measured is moved step-by-step on a transparent belt under a row of photo-electric cells C and the cells masked by the area at each step are counted. At each step a pulse turns on a first coldcathode tube T0, Fig. 4, so that clock pulses from a source G cause an " on " condition to pass along a chain of tubes T1 to T10. Each tube produces a pulse in its cathode circuit but only those pulses associated with a masked cell C pass on to a counter N, the other pulses being shunted to earth.
Patent ES-311570-A1 (ES)
Title: Nuclear reactor safety and/or control system
IPC: G21C7/10
Filed: 1965-04-08
Abstract: A nuclear reactor articulated control member is formed of absorber plates hinged together to form a linear series which may be extended or contracted vertically, lengthwise along the series, about the hinges. The degree of extension determines the amount of absorber material inside the reactor core and hence the degree of reactivity. The control member and the associated winch motor are mounted on a plug slidable within an aperture in the biological shield. When fully extended, the plates are shaped to permit the edges of plates in adjacent series to engage and to thus form a succession of frusto-pyramids. The downward motion is damped at the fully extended position, by the winch mechanism.

Patent ES-337199-A1 (ES)
Title: Fm demodulator circuit for use in a facsimile system
IPC: H04N1/00
Filed: 1967-02-23
Abstract: A frequency discriminator comprises: a first switching element 20 cross-coupled with a second switching element 40, and coupled to a third switching element 30 and a fourth switching element 100 arranged to be actuated only when the first and third elements are in a predetermined state. Elements 20, 40 form a monostable circuit which resets in the interval between input pulses, and capacitor 72 charges between input pulses to a potential dependent on the length of the interval. Thus each negative input pulse at 16 switches transistor 20 on and switches transistors 30, 40 off. After a period dependent on the charge on capacitor 72, and hence on the frequency, transistor 30 switches on again, and after the reset time of the monostable circuit transistor 20 switches off again. During the time interval that both transistors 20, 30 are on, AND gate 100 is enabled to feed width modulated pulses to output terminal 18. These are then fed to a low-pass filter to extract the modulation signal. The demodulator is used in a facsimile system.

Patent ES-345786-A1 (ES)
Title: Method of producing steel bars by continuous casting
IPC: B22D41/50
Filed: 1967-09-22
Abstract: In a method of continuously casting steel castings by pouring steels of different chemical composition in at least two jets simultaneously into a mould to form a casting having a peripheral zone of one steel and a core of another steel, the peripheral zone is formed by at least one jet which does not penetrate deeply into the liquid steel in the mould but spreads substantially horizontally near the free surface of the steel in the mould, and the steel for the core is provided in one other jet that penetrates to a greater depth in the liquid steel in the mould in a direction principally confined to the longitudinal axis of the casting. In casting a rectangular slab of steel having a pair of long side walls and a pair of shorter side walls, two jets, one at each end of the mould, are used for the peripheral zone steel and a central jet is used for the core steel. The central jet is formed by a pouring spout that extends below the surface of the liquid steel in the mould and may have additionally two lateral outlets that direct some of the steel parallel to the layer sides of the mould. The two outer jets may also be confined in pouring spouts that direct the steel in a sideways substantially horizontal direction. The steel casting may comprise an unkilled or partly killed steel on the peripheral zone and a partly or fully killed steel in the core, the killing being done by the addition of aluminium, manganese, silicon, vanadium or combinations thereof. The steel tapped from a melting vessel into one or more ladles and then into a tundish having a number of jets and which may have partitioned zones therein. Aluminium may be added to the steel in the tundish, into the jet within the mould, in the form of a wire passed through the wall of a pouring spout, or in a combination of these methods. Alloying elements may also be added to the steel.

Title: Process for the Production of Tubular Poles Made of Glass Fiber Reinforced Synthetic Resin and Tubular Pole and Device for the Production of the Same
IPC: B29C53/80
Filed: 1967-12-12
Abstract: Fibre reinforced tubular resin bodies such as telegraph or high-tension poles, are made by casting a liquid phenol formaldehyde-hardener mixture in a mould cavity formed between a conical core 4 and a heated outer mould 6. The reinforcements 1 and 2 are tensioned between fixed pegs 9, at the lower end of the cavity and arms 11, carried by a longitudinally adjustable plate 17, at the upper end of the cavity, contact between the reinforcements themselves and between the reinforcements and the mould or core being prevented by rings 19 and circumferential rovings 5. In operation, the reinforcements are applied over the core whilst it is horizontal, the outer mould placed over the core, and the whole then pivoted to a vertical position (see Fig. D, not shown). The resin hardener mixture is then introduced from a mixing vessel, into the bottom of the mould through an inlet 8, after which the resin is gelled and partially cured, the reinforcements simultaneously being tensioned by movement of plate 17. The core is subsequently removed and the resin then fully cured, after which the finished pole is cooled and removed from the mould.
