Patent number: 4334790Abstract: Keyboard generated signals are digitally encoded and converted to varying voltages for application to a coil for generating magnetic forces. The magnetic forces act on a spring mass system including a type disc to rotate the type disc to a selected angular position. The rest position of the disc at any selected angular position is established when the applied magnetic force and the force of an oppositely acting spring reach equilibrium condition. The spring stores or releases energy according to whether the applied magnetic force is greater or less than the existing spring force. The parameters of the system are so chosen that movement from one angular position of rest to another is smoothly accomplished in a given time.Type: GrantFiled: December 3, 1979Date of Patent: June 15, 1982Assignee: Triumph Werke Nurnberg A.G.Inventors: Manfred Link, Diethelm Puch, Peter Zahner, Karel Suc

Patent number: 4313681Abstract: Mechanism responsive to discrete character signals is provided for selectively rotatably positioning a type disc clockwise or counterclockwise from a home position to present the selected character on the type disc for printing. The mechanism comprises a driven lever pivoted intermediate its ends which is cycled about its pivot in response to each character selector signal from a keyboard. When cycled, one of the arms of the driven lever is adapted to drive an associated rocker from a rest position and through its other arm is adapted to allow an associated rocker to be driven from a rest position. The movement of the rockers, the magnitude of which is determined by interposers representative of characters which are selectively interposed between associated arms and rockers at various distances from the pivot of the driven lever, controls the pivotal movement of associated frame supported crank levers spring urged against the rockers.Type: GrantFiled: May 1, 1980Date of Patent: February 2, 1982Assignee: Triumph-Werke Nurnberg A.G.Inventors: Josef Lendl, Diethelm Puch

Patent number: 4297040Abstract: A method and apparatus for positioning a type disc in a balanced force system wherein applied selective forces to effect angular positioning movement from an old to a new position are brought into equilibrium with opposing spring forces. Electronic positioning controls are provided to generate forces for application at different times during a positioning movement whereby positioning movement from one equilibrium position to another is accomplished without damping and without overshoot in the shortest optimum fixed time and with the least expenditure of energy. The electronic positioning controls first apply a force corresponding to a new position and then, midway of the angular positioning distance between the old and the new position, apply a force corresponding to the old position to decellerate positioning movement until natural oscillation about the old position carries the disc to the new position at which time the force corresponding to the new position is again applied to hold the new position.Type: GrantFiled: June 13, 1980Date of Patent: October 27, 1981Assignee: Triumph-Werke Nurnberg A.G.Inventors: Diethelm Puch, Norbert F.

Patent number: 4209260Abstract: A wire matrix print head having print wires subject to wear at their printing ends are biased by return springs against one side of one end of armatures, the other sides of which bear against a gap adjusting ring. The other end of each of the armatures is spaced by a predetermined gap from the pole piece of associated electromagnets which, when energized, drive the armatures about pivots intermediate the ends of the armature against the bias of the return springs. The ends of the armatures are formed with a step on the side initially placed in contact with the drive end of a print wire so that when the print wires are worn the armatures can be flipped over to present the unstepped side in contact with a drive wire with the result that upon movement of the adjusting ring to restore the gap between the armature and pole piece the print wires are pushed to a rest position closer to the printing plane by the depth of the step.Type: GrantFiled: December 29, 1978Date of Patent: June 24, 1980Assignee: Triumph Werke Nurnberg, A.G.Inventor: Friedrich Jung
