Abstract: The basic device for connecting fluid logic circuits comprises a base plate, a sealing film, a back seal plate, a circuit plate, a front seal plate and a gasket adapted to have a plurality of logic modules mounted thereon. The front seal plate is perforated to provide for connection of every possible logic input and output to the circuit plate which is provided with perforations and interconnecting channels for the required hole-to-hole connections. The back seal plate seals the channels and is perforated to allow communication with input and output lines. The seal film is perforated only at selected locations and the base plate is completely perforated with holes adapted to accept terminals for the input and output tubing connections.

Abstract: ELECTRO-MAGNETIC PRINT HAMMER An electro-magnetic print hammer comprises a single magnetic hammer element in which an impact mass is coupled to a pivotted armature by flexible stem. The hammer-stem has (N+1/2) periods of oscillation at its resonant frequency during the free flight time of the hammer mass. A permanent magnet with a strong magnetic force which decays rapidly with distance holds the hammer element fixed upon motion of the armature until the armature torque exceeds the magnet holding force to cause -the hammer mass to break loose with a snap action. Stop means prevents armature impacts with the operating pole piece of a stator core. The visco-elasticity of the armature stop matches the rebound characteristics of the print medium when impacted by the hammer mass.

Abstract: ELECTROMAGNETIC PRINT HAMMER COIL ASSEMBLY A heat exchange system for an electromagnetically operated print hammer of a print hammer bank provides internal and external heat transfer for the operating windings. A non-magnetic metal bobbin of the heat exchange system provides conductive transfer of heat from the interior of the operating winding to the magnetic core. Flat parallel plates of magnetic material are attached to the sides of the operating winding for external heat transfer and magnetic flux shielding. The plates may have multiple laminations having different saturation and permeability characteristics.
