Title: Path interpolator for NC machine tools - has circular path determined by linear interpolation based upon polynomial evaluation
Inventor: KIRCHHOFER HEINZ
IPC: G05B19/414
Filed: 1979-11-12
Abstract: The control of a cutter along a circular arc path in a machinery operation is provided by a numerical control system that uses interpolation based upon a second order polynomial. The system possesses the advantage that 'x' and 'y' interpolations are executed in parallel. The circular path to be machined is divided into segments of angle 2 phi (phi) and radius 'r'. The path is interpolated into a number of straight line segments (5a, 5b, 5c) that fall into the tolerance band. The x and y parameters are evaluated by parallel processing in real time of polynomial equations: x = bx.s2+CxS+dx y = by.s2+CyS+dy. This enables high cutting feed rates to be used.

Title: Neutralising and removing acidic pollutants from combustion fumes - by treating with steam atomised alkaline suspension
Inventor: MARNET CHRYSANTH DR
IPC: F23J15/00
Filed: 1980-10-03
Abstract: In neutralising and sepg. acidic pollutants in fume gas from combustion units, a viscous suspension of alkaline solids, e.g. lime, in water is converted, using residual heat in the reaction, into dry neutral salts which with flue dust is removed by a standard separator from the discharge gases. The suspension enters the discharge flue in the unpressurised state and is atomised by a transverse current of steam. The amts. of alkaline material and steam are automatically adjusted to keep the neutralisation process generally stoichiometric. The system is esp. for refuse-burning units and uses steam instead of the previously known pressurised gas for feeding the neutralising material.

Title: Activating method for matrix liquid-crystal displays with position marking
Inventor: YASUDA SHUHEI
IPC: G09G3/36
Filed: 1981-02-25
Abstract: In a novel activating method for a matrix liquid-crystal display or the like, only a single cursor row (3) is activated during the row scanning in connection with the displaying of at least two rows of alphanumeric characters. The two-part row scanning is effected row-sequentially, a cursor row not required being permitted in each case in one row. This makes it possible to reduce the number of rows to be scanned, increase an available voltage of importance to the pixel activation (Figure 2) and obtain as an advantage good contrast and an improvement in the viewing angle characteristic of the activated display device. <IMAGE>
