Title: Apparatus for controlling the movement of light particles
IPC: B03C3/88
Filed: 1972-04-26
Abstract: 1381783 Electrostatic separators S MASUDA 26 April 1972 [12 May 1971 31 May 1971] 19312/72 Heading B2J [Also in Divisions B8 and H2] An electrostatic dust precipitator comprises a.c. energised electrodes associated with a layer of dielectric material so that when dust laden gas is directed on to the dielectric layer, the dust particles become charged and are then repelled by the electric field set up by the electrodes. The embodiment shown in Fig. 7 includes two porous dielectric cylinders 86, 87 associated with electrodes 88, 89 and 90, 91. The gas passes through the cylinders and leaves by outlet 96. The dust is repelled from the inner surfaces of the cylinders by the electric fields and falls under the force of gravity into a hopper 85. If the electrodes are connected to a polyphase supply Fig. 8 (not shown), a downwardly moving electric field assists the force of gravity. The electrodes may be connected alternately to a d.c. supply and an a.c. supply, Fig. 10 (not shown), the d.c. fields causing the particles to adhere to the inner surfaces of the dielectric cylinders and the a.c. fields causing the dust to fall into the hopper as in the Fig. 7 embodiment. The precipitator may include a single dielectric cylinder, Fig. 9 (not shown) having electrodes on its inner and outer surfaces, a d.c. field being set up between the a.c. energised inner and outer electrodes to prevent the passage of fine dust particles through the porous cylinder. In a modification of the Fig. 7 embodiment, (Fig. 10), the cylinders are formed of electrically insulated, spirally wound electrodes placed in contact with one another so that the insulation on the electrodes forms the dielectric layer. The gas passes through the interstices between adjacent insulated electrodes and the dust falls into a hopper as in Fig. 7. In a further embodiment, Fig. 12 (not shown), a single cylinder is formed of hollow insulating tubes spirally wound and in contact with one another. The electrodes are formed as a layer of conductive paint on the inner surfaces of the tubes and fluid is passed through the tubes so that when the dust laden gas is hot, the apparatus functions as a dust precipitator and heat exchanger. All of the above embodiments may employ corona discharge electrodes such as 99, 99', Fig. 7. In a further embodiment, Fig. 13, dust laden gas enters at 95 and leaves at 96 after passing over two sets of dielectric plates 191, 192 in which are embedded electrodes 201-212 and 221-225 and which are associated with corona discharge electrodes such as 193. The electrodes in the dielectric plates are connected alternately to earth, which causes the dust to adhere to the dielectric plates, and to an a.c. supply, which causes the dust to fall into hoppers 85, 85' as in the Fig. 7 embodiment: A further embodiment, Figs. 20, 21 (not shown) includes plates of woven material, the electrodes being included in the weave or being fixed to the woven plate.

[Also in Group XXXV] A magnet system, especially suitable for tripping a circuit-breaker, comprises a main magnetic circuit including a permanent magnet, two ferromagnetic cores extending from the poles of the permanent magnet to two polepieces to which an armature is normally attracted, and an auxiliary magnetic circuit including an H-shaped member of ferromagnetic material located between the two cores and spaced therefrom to act as a shunt across the main magnetic circuit so that upon excitation of the auxiliary circuit the attraction of the armature is reduced sufficiently to release it. The auxiliary circuit may be excited by D.C. or single- or three-phase A.C. A three-phase arrangement comprises two permanent magnets 1 and 2 bridged by a ferromagnetic member 21, two solid cores 4 and 5 extending from the magnets 1 and 2, and two laminated extension cores 6 and 7 terminating in pole faces 15 and 16 to which the armature 3 is attracted against the action of a releasing spring on the armature spindle 17. An H-shaped ferromagnetic core 8 is located between the cores 6 and 7, and three coils 13 or 14 connected to a three-phase supply with one phase reversed provide auxiliary excitation, the connections being such that the direction of flux is as shown by the arrows to divert the main flux across the H-shaped core and thus reduce that through the armature, this effect being independent of the instantaneous direction of A.C. The cores are embedded in synthetic resin, preferably by moulding in two sections which are subsequently joined by a filling-piece 29, all abutting magnetic faces being ground and polished. Fillers may be incorporated in the resin so that its thermal expansion characteristic will match that of the cores. Protective cut-out arrangement (Fig. 4).-To trip a circuit-breaker the coils 13 and 14 may be energized by current transformers Tr upon operation of a relay Mb which opens contact c. Release of the armature under the action of spring Uv lifts arm Uh to effect rotation of a D-shaft which operates the breaker tripping mechanism.
