Title: Plastic bottle blowing machine - including waste separator
Inventor: KADER RAINER DIPL-ING
IPC: B29C49/72
Filed: 1968-12-07
Abstract: Blow moulding apparatus having a split mould (129) which clamps about one or more tubular thermoplastics parisons (112) which have just been extruded (111) and conveys the parison(s) by a mechanically pivoted movement (131a) to a point beneath a blowing station (115) where pneumatic nozzles (116) engage the top(s) of the parison(s) and inflate them within the mould cavity. As soon as the mouldings are sufficiently chilled to be self-supporting, the mould opens, leaving the mouldings suspended from the blowing nozzles. The return movement of the mould to enclose the next parison(s) brings into position beneath the dangling, cooling mouldings some form of gripping mechanism (126) which is mounted rigidly on the moulds (129) or the lever system on which the moulds move. As soon as the mouldings are set sufficiently to be clamped, the mould closes about the next parison(s) and simultaneously the mouldings are gripped. The mouldings are conveyed to a discharge chute or conveyor as the mould moves back from the extruder to the blowing head with the next set of parisons. Pref. the traversing action or the final removal of the mouldings carries them past automatic deflashing equipment.

Patent DE-2013255-A1 (DE)
Title: Electron beam/laser machining
IPC: H01J37/21
Filed: 1970-03-20
Abstract: The position of the focal point is controlled in three orthogonal axes relative to the workpiece and is deflected in the x & y axes at two frequencies (which may be equal) and oscillated along the z axis at a third frequency smaller than the other two, this being synchronous with the gating signals in a bridge demodulator used to provide a control signal for the focussing circuit. Secondary radiation from the surface of the work piece is picked up by a detector and amplified selectively at fundamental frequencies in two channels which control the position control servos for the workpiece in the x & y axes. The harmonic content of the signal picked up by the detector is amplified after band pass filtering and used to control the bridge demodulator. The system can be used for cutting, drilling, welding or inspection to high accuracies and maximum efficiency.
