Title: Process and apparatus for reacting finely divided solids with gases while simulating a fluid
IPC: B01J8/18
Filed: 1947-07-14
Abstract: In a furnace for the calcination of lime (see Group XII), powdered limestone is fed by a screw 37 into a casing 11 which is divided by apertured partitions 17, 44 and 53 into preheating, treatment and cooling chambers 13, 12 and 14, respectively, and compressed air or gas is supplied from a wind-box 58 and flows upwardly through the partitions to the outlet of a dust separator 29.  The limestone forms a bed on the partition 17 which is maintained in a fluidized state by the upwardly-flowing air or gas, the surface level of the bed being determined <PICT:0658611/III/1> by the upper end of a valve-controlled pipe 41 through which the preheated material overflows to form a bed on the partition 44 which is similarly maintained in a fluidized state.  A number of burners 62 for the injection of gaseous, liquid or pulverized fuel with or without air are arranged in the chamber wall, a further gas burner 61, used when starting up the furnace, being provided in the chamber 14.  Calcined material overflows from the bed in the chamber 12 through a pipe 46 to form a similar fluidized bed in the chamber 14 and the cooled material overflows through a discharge pipe 54 fitted with a valve 55.  Specification 590,882 is referred to.

Abstract: 198,923. Ward Leonard Electric Co., and Bullinger, F. H. July 7, 1922. Brush-holders; terminals and accessories, arrangement on machine.-A generator driven from a variable-speed source such as the engine of an automobile has a regulator mounted, upon the brush frame 6; the regulator frame forms one of the regulator terminals, and a part is directly connected to an adjacent brush-holder. The regulator frame has insulation 12 interposed between it and the brush frame, and consists of a sheet of non-magnetic metal bent at right anglas into two portions 13a, 13b. An extension 13<c> of the underside 13b is connected to the upper brush-holder 10. Another extension 13d serves as a support for a tubular resistance 14. The regulator magnet consists of an E-shaped stamping 15 which extends from the portion 13a over the commutator. One end of the exciting coil 16 is connected to the stamping and the other end to an insulated lug 17. The vibratory armature is a metal strip 18, Fig. 3, secured at one end to a phosphor-bronze strip 19 by means of a sheet-metal piece 20 having bent-over tongues 20<a>. A fixed support for the strip 19 is formed by a pair of metal blocks 21 clamped to the portion 13a of the regulator frame by a sheet-metal piece 22. The piece 22 has tongues 22a passing through grooves in the frame, and has also extensions 22<b>, 22<c> which act as a fulcrum and support for the armature spring 25. The tension of the spring can 'be adjusted by bending the portion 22<c>. The free end of the armature carries a contact 18<a> normally held against the contact 23 of an insulated portion 24 which is in electrical connection with a terminal 26<d>. When the current rises above a predetermined value, the armature 18 is attracted, contacts 18a, 23 are broken, and the resistance 14 is put into the field circuit. A removable sheetmetal cover 29 serves to enclose the parts.
