Title: Impact matrix print head solenoid assembly - has permanent magnet to hold print wire armature and deflect spring with electromagnets to overcome magnetic force
IPC: B41J2/285
Filed: 1977-05-23
Abstract: The printing head increases the resulting impact force of the print needle by combining forces from oppositely-directed magnetic fields. A permanent magnet holds an armature connected to a print wire in a retracted, non-printing position, thus applying a holding force to the armature and deflecting a spring coupled to the armature. An electromagnet is energized to produce a magnetic field which acts on the armature and overcomes the field of the permanent magnet. The field produced by a second electromagnet has a component which urges the interconnected armature and print wire away from their retracted position and toward a printing position.

Title: Flow meter inside fluid control valve - has shuttle piston on main valve piston rod for closing valve
IPC: E03B7/07
Filed: 1977-07-07
Abstract: A flow control valve has a valve piston for closing the valve. An axial extension of the piston is used to connect a rotary flow meter when the valve piston is in the open position. When the required fluid vol. has been transferred, the flow meter helix operates a lever, which then opens an auxiliary valve. This allows pressure increase inside the cylinder of a shuttle piston. Since the shuttle piston is located on the main valve piston rod, its movement retracts the main piston and thus shutting off the valve.
