Fine powders produced are of size less than 100 microns, preferably less than 10 micron, more preferably less than 1 micron, and most preferably less than 100 nanometers.

The apparatus comprises a screen (3) for separating the particulate material into an undersize fraction and an oversize fraction.

The present invention provides α-alumina powders comprising α -alumina particles of which at least 80% of the α -alumina particles have a particle size of less than 100nm.

g) mortars with a caliber of less than 100 millimeters

The particulate solids comprise clay and mineral particles of size below 50 μm.

The top level of a wider gage rail (220) maintains the same height, and a top level of the narrower gage rail (210) is inclined or declined along the wider gage rail (220) in a longitudinal direction.

The smaller grain size provides buttons having greater strength and reduced tendency to form cracks.

During anterior referencing, the gauge allows the surgeon to select the smaller size prosthesis if the size falls in between available sizes.

ammunition for calibers less than or equal to 19.1 mm.

The ammunition are to be used in guns of a calibre equal to or less than 19.1 mm.
