Title: Blow moulding necks, with close tolerance - using one nozzle per moulding in a two stage inflation cycle
Inventor: MEHNERT GOTTFRIED
IPC: B29C49/32
Filed: 1973-10-30
Abstract: An extruded tubular parison is clamped in a preforming mould and dilated in two stages remote from the extrusion axis by suitable relative motions, while being served by a specific nozzle for shaping and calibrating the neck and admitting the inflation pressures for all stages. The moulds are independently opened and closed at the three stages (parison cut-off, pre inflation, post inflation and ejection). A sequence of nozzle may be used to produce successive mouldings. Method is used esp. for mfr. of containers with internally ribbed or threaded necks and/or requiring a coplanar mouth. Introduction of only one nozzle per moulding avoids any local drag or shear effects which would require greater nominal neck wall thickness to ensure adequate strength. Independent mould action permit optimum balancing between parison seizure, pre inflation and the chilling cycles.

Title: Piston valve with inclined valve seat - uses fluid pressure to reduce valve closing force
Inventor: JANKOVIC MLADEN
IPC: F16K1/50
Filed: 1974-06-26
Abstract: A shut off valve for fluids has a valve piston which moves across the flow at right angle. The leading face of the piston is inclined at 45 deg. so that it matches the valve seat which is inclined at the same angle. The piston is operated by a valve spindle or by remote control through a pilot cylinder. In order to reduce the piston operating force to a minimum, when shutting the valve the pressure increase in the fluid is allowed to act on the right angled trailing face of the valve piston. The inclined valve seat in the flow line does not restrict its cross section thus no losses occur when the valve is fully open.
