Abstract: 836,356. Batch mixing-machines. BRI-. TISH THOMSON-HOUSTON CO. Ltd. Jan. 10, 1957 [Dec. 13, 1955]. No. 35767/55. Class 86 [Also in Group XXXV] An apparatus for stirring molten metal in a container 7, Fig. 1, comprises two or more electromagnets situated adjacent the container so as to produce a magnetic flux therein, together with means for applying pulses of unidirectional current sequentially to the windings 1, 2, 3 of the electromagnets whereby a travelling magnetic field is produced in the metal. The means for applying the pulses to the winding 1 is shown in Fig. 2 and is the same for the windings 2, 3. The winding 1 is supplied from a rectifier 12 fed with A.C. through a saturable reactor 13. A control winding 14 on the reactor is supplied from a rectifier 15 fed from the same A.C. source under control of a switch 16. When the switch 16 is closed the reactor is saturated and of low impedence and thus the winding 1 is excited. The switches 16 of the windings 1, 2, 3 are operated in sequence by a rotary cam. In another embodiment the electromagnets each have two windings whereby the magnetic flux may be reversed. The windings of each electromagnet are either oppositely wound or wound in the same direction and fed with reversed currents. The pulses may be arranged to overlap.

Patent GB-364685-A (GB)
Abstract: 364,685. Ornamenting. JOHNSON, J. Y., 47, Lincoln's Inn Fields, London.- (Compagnie Pan-Continentale Soc. Anon., Luxembourg; 33, Boulevard Royal, Luxembourg.) Aug. 31,1931,No.14071/30. [Class 93.] Porous or non-porous substances, such as metal, wood, cardboard, and asbestos, are treated to render them suitable for subsequent decoration by the application of two or more layers, the first of which contains shellac to cause it to adhere to the base, and nitrocellulose to impart properties similar to those of nitrocellulose enamels. The surface is first cleaned and roughened by means of a sand-blast or by sandpapering, and is then sprayed with a solution containing a small amount of aniline dye and equal'amounts of shellac dissolved in denatured alcohol and pyroxylin dissolved in ethyl and butyl acetate. A further coating of this solution can be applied if desired. A second layer, consisting of a small amount of a filler such as lithopone or silica, and ester gum and pyroxylin in solvents which will not dissolve shellac, e.g. ethyl acetate and benzol, is then applied by a brush or the like. The ester gum is itself adhesive, and the' pyroxylin solvent will tend also to dissolve the pyroxylin of the first layer so that an adherent coating will be formed. A third layer is then applied by spraying, and consists of gum dammar and pyroxylin dissolved in amyl acetate, and diluents such butanol or toluol, the solvents acting to dissolve slightly the pyroxylin of the first two layers but not the shellac. The upper surface can then be decorated by means of a pyroxylin enamel.

Patent GB-862637-A (GB)
Title: Fluidized-bed reactor
IPC: B01J8/24
Filed: 1958-11-17
Abstract: <PICT:0862637/III/1> A vertical pipe 18 is located at the side of the reactor 10 opposite the feeder 17 and extends from the bottom of the bed B just above partition 16 to a height within the freeboard F well above the bed.  Pipe 18 has a minimum diameter enabling solids therein to remain fluidized, but has a relatively large height-to-diameter ratio to minimize vertical back-mixing of solids therein.  A downwardly sloping overflow pipe 21 extends from the intermediate portion of pipe 18 through the side wall of the reactor. The effective height-to-diameter ratio of pipe 18 measured from its lower end to the overflow pipe 21 should be at least 10/1 and preferably in the range 15/1 to 20/1.  Preferably the overflow contains a shut off valve 22.  Preferably a cone-type plug valve 23 is mounted for vertical movement above the upper end of pipe 18 and is adapted to restrict flow of gas from the pipe. Preferably also an inlet pipe 24, which contains a normally closed valve 25, leads to the lower portion of pipe 18 and is adapted to admit gas for adjusting the bed depth downwardly from its normal level.  Finely divided solids feed into reactor 10 through the feeder 17, while gas enters through inlet 12, flows upwardly through partition 16 and bed B, and leaves through outlet 13, fluidizing the solids in bed B and at the same time reacting in some way therewith.  The solids and/or gas can be preheated if required for the reaction, or the reactor can be equipped with heating or cooling means if needed.  Control of the extent to which valve 23 restricts flow from the top of pipe 18 or control of the valve 25 regulates the location of the levels P and M. If it is necessary to empty the reactor completely, feeding is stopped and valves 15, 23 and 25 fully closed.  Gas continues to enter the reactor through inlet 12 and causes pressure within the reactor to increase.  The pressure increase can be relieved only by escape of gas through the overflow pipe 21.  In thus escaping, the gas carries solids from the bed after the fashion of a dense phase pneumatic conveyer.
