Abstract: 804,014. Blending pulverulent materials. FULLER CO. May 30, 1956 [June 28,1955], No. 16757/56. Class 86 Pulverulent materials in a bin or silo 1 are blended by passing air, &c. upwardly through the several vertical zones, e.g. A, B, C, D, of the silo, the air passing into at least one zone, say A, being introduced in pulses and in such volume and pressure as to cause a fluidization of material in that zone and that passing into a contiguous zone or zones being in such volume and pressure as merely to aerate, but not fluidize, the material in these zones. The silo, which may be of any size and crosssection, has an inclined bottom 3 upon which is mounted a plurality of closelyspaced aerating units 6 each comprising a chamber 8 which is closed at the top by a porous gas-permeable cover 7 and is fitted with a flexible air inlet tube 15 adapted to be connected to headers 9 which are located in channels 10 in the upper surface of the silo bottom 3 and are themselves connected to diametrically-extending manifolds 11, 12, 13, 14. In order to provide a uniform supply of air to the several aerating units, irrespective of their distance from the manifolds 11, 12, 13, 14, the inlet tubes 15 are provided with restricting orifices, not shown. The manifold 11 may be supplied with air from two independent compressor units 16, 17 through, respectively, a conduit 18 and branch 19 with check valve 22 or through pipes 28, 29, conduit 31 and branch 32 with a control valve 36; the other manifolds are connected to the compressor units in a similar manner. The pipe line 28, 29 is fitted with a manually-operated valve 41, normally open, and an automatic intermittentlyoperated remotely-controlled valve 42 with timing mechanism 43, and a pipe 44, with manual valve 45, by-passes said valves 41, 42. The arrangement is such that with the valves 36, 37, 38 closed and valve 39 open, air in sufficient quantity to effect an aeration of the pulverulent material will be supplied from the unit 16, Through the conduit 18 and pipes 19, 21, 25, to the aerating units 6 in zones B, C, D; simultaneously the unit 17 will supply a larger quantity of air, sufficient to effect fluidization, in the zone A, the valve 42 being continuously operated so that the air is introduced into this zone in pulses. The several zones are subjected serially to the air in a fliudizing volume in any desired cycle by connection of the valves 36, 37, 38, 39 to suitable timing mechanism. More than one zone may be subjected to fluidization at the same time, and the supply of aerating air to contiguous zones may be dispensed with.

Filed: 1943-10-20
Abstract: 571,170. Electric induction heating. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. Oct. 20. 1943, No. 17293. Convention date, Nov. 5, 1942. [Class 39 (iii)] An induction heating coil 5 for heating a rapidly moving steel strip 4 in a tinplate-flowing operation is provided with means for preventing corona or space-current discharges due to high electrostatic stress between the coil and the strip. The coil is water-cooled, is connected to an oscillation generator 12 at its ends, and is earthed at the mid-point 6 where water enters. The strip is enclosed by an insulating liner 13 of asbestos board or a moulded material, preferably spaced from the coil so that most of the voltage drop occurs in the space 17. Corona between the strip 4 and liner 13 is prevented by an earthed semi-conducting coating 18 painted on the outer surface of the liner 18, and extending axially beyond the coil into a region where the alternating magnetic field is relatively weak. The coating 18 may be a finely divided graphite suspension, or a varnish containing powdered charcoal, or titanium dioxide which has been partly reduced, and is of such resistance and thinness that it is not materially heated. The coil 5 may be partly embedded in an insulating casing 21. To avoid a complete eddy current path around the shield 18, the shield is formed by separate axial conducting strips connected circumferentially only at the ends which are earthed. The strips do not extend across the centre of the axial length of the coil 5 where shielding is unnecessary. The Specification as open to inspection under Sect. 91 describes also a modification, Fig. 3 (Cancelled), for heating a wire 24, in which two concentric insulating liners 13<1>, 23 are used, the space 18' between being filled with a semiconducting composition acting as a shield. This shield is earthed at 19<1> and the electrostatic stress is taken by the liner 23. This subject-matter does not appear in the Specification as accepted.
