Abstract: Pulverized coal is slurried with water then oil or if desired oil and pulverized alkalis preferably lime or limestone is added and the mixture subjected to sonic vibrations with an energy density of at least 11.625 watts per cm2. Liquid suspension is produced and any excess water or oil separates out as a separate phase. Normally excess oil is used and the excess oil phase can be recycled. The resulting dispersion is utilized and burned in a furnace. A clean flame is produced which has the characteristics of an oil flame and not a powdered coal flame. The addition of lime is optional as its purpose is to reduce sulfur dioxide in burning where the coal contains sulfur. If there is no sulfur or so little as to meet environmental standards the addition of lime may be omitted. The amount of lime is preferably at least about twice stoichiometric based on the sulfur content of the coal. Up to 80% of sulfur dioxide produced on burning can react with the lime and the calcium sulfate produced removed by conventional particle separators.

Abstract: The heat-sealing unit has a plurality of elongated heating elements (11) which are arranged parallel at a distance from one another on a convexly curved carrier (12). Said heating elements form a slideway for a continuous set of business forms consisting of at least two layers (14, 15) and serve for the localised heating of hot-melt adhesive arranged between the layers. Downstream of the heating elements there is arranged a pressing device (24, 25) which brings the heated layers into intimate contact with one another. By means of the direct contact between the set of forms and the heating elements and the localised heating, the heating energy can be kept small, it being possible at the same time to prevent overheating of the set of forms. <IMAGE>

Abstract: A fluidized bed separator is disclosed, for use in dry processing of a mixture of solid particles of different specific weight.  The suspension bed of the separator is associated with an air deck operating with a single-particle-layer and adapted to receive heavy particle fraction discharged from the suspension bed and still containing a small portion of light particles.  The air deck operates such that a pure heavy particle fraction travels in a direction opposite to that of light particle fraction, the latter being recirculated to the suspension table as it still contains a small portion of tiny heavy particles.  Since the air deck is preferably secured to the suspension table, the reciprocating drive of the table also drives the deck, the level of the deck relative to the suspension table is selectively adjustable.  The device is extremely simple compared with prior art and is more universal as its operation is virtually independent on the shape of particles of the respective fractions.  It is particularly suitable in processing mixtures having relatively small volume of heavy particles, wherein a pure heavy particle fraction is to be obtained.

Abstract: The invention relates to a process for the preparation of a fibre-free material from peat-based fibrous material. In this process, the fibres of the peat material are exposed and converted into a suspension of peat material, which is subjected to at least one sorting operation. To obtain a high yield of usable material according to the invention, the fibre-free suspension obtained by the removal of fibres from the suspension of peat material is subjected to a separation process in which the organic material remaining in the suspension after the removal of the fibres is separated off from the fibre-free suspension. This organic material may be present e.g. in the colloidal form or as particles measuring less than 0.2 mm. The dry-matter content of the organic material isolated by the separation process is then increased by dehydration.

Abstract: The invention relates to a directive broad band antenna element of V-shaped dipole type with bent wire- or strip-shaped dipole antenna (A). The dipole antenna is divided into two sections, a first section (S1) where the radiation is minimized (or prevented) by a small distance between the conductors and a reduced phase velocity, and a second section (S2), where the radiation is enhanced by increasing the phase velocity by means of introduced series capacitances (C1, C2, . . . Cn). The series capacitances have respective values which depend on the local angle between the dipole conductors and a radiation axis (x), and are chosen such that the phase velocity is increased to a value which effects radiation contributions from different parts of the conductors to cooperate in the desired radiation direction. Because of the series capacitances, the curvature of the conductors can be made much sharper and the extension of the antenna in the radiation direction will be much smaller for a given frequency band than in the case without series capacitances. This in combination with the reduced (inhibited) radiation from the first section (S1) causes the displacement of the center of radiation (the phase center) with frequency to be limited. Thus the antenna element can operate over a very extended frequency band (on the order of 2 to 3 octaves) and still serve as a primary radiator for illuminating a secondary radiator having a focal point, such as a parabolic reflector or an electromagnetic lens. The reduced phase velocity at the first section (S1) can be achieved by means of a small dielectric disc (D) place between the dipole conductors of the first section and/or zig-zag shaped or inwardly toothed conductors in the first section (S1).

Abstract: A process in the forming of a paper web, the dewatering of the pulp web, and of the paper web being formed comprises feeding the pulp suspension jet from the slice of the headbox into a gap formed by two wires, the gap becoming narrower in the feeding direction of the pump suspension jet. Water is removed from the pulp web when the web is in compression between the carrying wire and the covering wire within the twin-wire forming zone, which begins immediately after the feeding gap. The twin-wire forming zone is curved towards the loop of the carrying wire with a curve radius which is selected large enough so that the wire tensioning pressure resulting from it and acting upon the pulp web becomes low and the water removed from the pulp web is not splashed from the inside surface of the wire loop by the effect of centrifugal force dependent upon the curve radius. The joint run of the wires is passed over an open-surfaced forming roller, so as to be curved within a relatively small angle towards the loop of the covering wire. The joint run of the wires is passed over a forming roller, so as to be curved towards the loop of the carrying wire. The formed web is detached from the wire and transferred into the press section of the paper machine. A specifically structured twin wire former carries out the process.
