Title: Control system for injection moulding machine - regulates resin temp., back pressure and throughput at each stage of extrusion stroke
Inventor: KOZAWA MITSUO
IPC: B29C45/76
Filed: 1975-09-26
Abstract: Control of an injection moulding machine iwth a reciprocatable extrusion screw-piston, involves measuring the temp. of the molten resin and that of the injection mould directly before or during the injection step. A correcting magnitude of the counter pressure for the screw piston is determined within a region of the controlled pressure which prevails after almost complete injection of the resin into the mould, based on the deviation of the measured temps. from pre-determined reference values, in order to correct the set value of the counter pressure. The corrected counter pressure is applied to the screw-piston so that the injection step proceeds until the injection period has elapsed and at this point the position of the screw-piston is determined. The residual quantity of resin from the injection shot carried out is calculated on the basis of the deviation of the measured or actual position from a position corresp. to a predetermined or pre-set-residual quality. The amt. to be metered during the next injection shot is thereby determined so that for each shot a constant residual quantity of resin is ensured. By varying (i) the speed of injection of the resin, (ii) the filling or charging pressure at the injection mould and (iii) the speed of rotation of and the counter pressure acting on, the screw-piston at each section of the injection and plasticising stroke, the range of variation of the injection moulding conditions is widened.

Title: Digital display practice target hit analyser - rotates target about hit hole for analysis by photo-transistor
Inventor: HUSCHER GEORG
IPC: F41J5/02
Filed: 1976-10-11
Abstract: The digital firing practice target hit analyser measures the distance between the hit and the target centre. This arrangement is used for air gun firing practice. The his spacing is digitally indicated in hundredths millimetres with illuminated figures and the hit analysis is carried out automatically. The target of dia. 50 mm is centered on a rotating flat plate by the hit hole. On rotating the boundary between the dark and bright areas covers periodically a distance equal to double the spacing in the target. A phototransistor is moved along on each plate rotation by one hundredth of a millimeter. When the phototransistor is directly above the bright area of the target then the collector potential is on logic zero and in dark area on logic unity. The potential change in the transition region is amplified for display purposes.
