Title: Combined grinding and drying process - having cyclone separator on recycle gas line to avoid putting excessive load on main dust separator
Inventor: DEUSSNER HERBERT DIPL ING DR
IPC: B02C21/00
Filed: 1979-07-27
Abstract: Process for drying and grinding of moist particulate materials uses hot gas in a grinding plant followed by a separator. The gas stream required for conveying the material is greater than that required to dry it and this is provided for by recycling same gas. The recycle gas stream is taken as a side stream from the main product stream and passed to a separate cyclone separator. The remainder of the gas flows to an electrostatic precipitator from which the gas is discharged to atmosphere. The process is for drying and grinding lignite or cement raw meal. It avoids having unnecessarily large final separators, reduces discharges to atmosphere, the size of plant and thus capital costs for the same size of plant.

Title: Solid state LF calling tone generator - uses inverter operating with variable mark space to produce desired frequency
Inventor: KORN JOEL DR ING
IPC: H04M19/02
Filed: 1979-11-16
Abstract: A solid state switch (Ts) controls the current from a battery (B) flowing through the primary winding (WP) of a transformer (WU). Secondary output windings (WA1,WA2) are connected to a switch (WR), and a feedback winding (WV) to a comparator (VV). The other comparator input is taken from a calling tone frequency generator (G). The switch (Ts) is controlled, via a NOR-gate (NG), from a monostable (M) whose control input is from the comparator (VV) and reset signal from a pulse generator (TG) operating at a frequency higher than the calling tone. The monostable output is thus a variable frequency resulting from the difference of control and reset frequencies. It controls the switch frequency from a min. at zero cross over voltage to a max. at crest voltage of the output. The switch (WR) is controlled by the tone frequency generator (G), and gives alternate positive and negative output half cycles.
