Patent DE-19928770-A1 (DE)
Title: Pressure injection molding machine with continuous extruder and separate injection cylinders is designed to avoid use of three way valves and prevent external leakage of e.g. filled plastic melt or thixotropic magnesium
Inventor: WOHLRAB WALTER
IPC: B29C48/405
Filed: 1999-06-23
Abstract: Injection units comprise cylinders with reversibly-driven stepped pistons dividing their volume into injection- and feed- chambers. The larger, leading piston areas occupy the injection chambers, the smaller, rear annular surfaces of the pistons occupy the feed chambers.  Ball non-return valves are connected in series with passages between chambers in each piston and cylinder unit. Cylinder outlets connect to the injection nozzle via injection channels and further non return valves. Feed chambers are directly connected via a feed channel system to the extruder head space. An Independent claim is included for the method of operating the injection molding machine. Each hydraulic cylinder is controlled so, during injection chamber filling via the hot channel, the feed chambers and the passages with the non return valves are essentially free of pressure, or under reduced pressure. Further developments of the machine and method are described. Preferred features: The double screw extruder has co-rotating screws. A four-shaft variant with eight screws is described. The feed chambers are connected directly via a hot channel to the extruder, i.e. with no intermediate arrangement of path-switching valves. The injection units are driven by e.g. double-acting hydraulic cylinders.

Abstract: A video display deflection circuit includes a source of a video signal (Y) for
displaying picture information contained in the video signal in a screen of a
cathode ray tube. The video signal provides selectively on-screen-display
information and non-on-screen-display information. A source of a first control
signal (OSD_FLAG) has a first value, when the video signal provides on-screen-display
information and a second value, when said video signal provides non- on-screen-display
information. A waveform generator (63) is responsive to the first
control signal for generating a second signal (63b) at a frequency that is related to
a deflection frequency having a first waveform, when the video signal provides on-screen-display
information, and a second waveform, that is different from the first
waveform, when the video signal provides non- on-screen-display information. A
modulator (31) generates a modulated correction signal (31b) by modulating, in
accordance with the second signal, a time-derivative signal (30a) produced from
the video signal, The correction signal is coupled to a scan velocity modulation
winding (L1) to produce scan velocity modulated deflection of the electron beam.
