    Abstract: A PRINT HAMMER ACTUATOR ASSEMBLY FOR HIGH SPEED A POSITION SENSING SYSTEM THAT DETECTS THE LOCATION OF EACH ELEMENT OF A PLURALITY OF ELEMENTS AS THEY TRAVERSE A PRINTERS. TWO ELECTROMAGNETICALLY ENERGIZED ACTUATOR CONSTRUCTIONS ARE PROVIDED, WHICH ARE MECHANICALLY EQUIVAPREDETERMINED PATH. THE SYSTEM IS DISCLOSED IN CONJUNCLENT BUT OF COMPLEMENTARY GEOMETRY SO THAT THEY CAN BE TION WITH A PRINTING ARRANGEMENT WHEREIN THE ELEMENTS ARE THE CHARACTER BEARING FINGERS ON A CONTINUOUS MOVING LOCATED TOGETHER IN A MANNER FACILITATING INDIVIDUAL REMOVAL OF THE ACTUATORS. THE ACTUATORS ARE LOCATED IN DIBELT. RECTIONS PARALLEL TO THE LINE OF PRINT BY ALIGNMENT COMBS FASTENED TO A BASE PLATE, AND LOCATED IN DIRECTIONS NORMAL TO THE LINE OF PRINT BY STOP BARS FASTENED TO THE BASE PLATE. 611

    Abstract: An underspeed and undervoltage protection system for an electromechanical printer. The printer includes a plurality of moving characters actuated by stationary print hammers. The speed of the moving characters is continuously monitored along with the input voltage to the printer system. A synchronizing signal is provided which indicates when the characters are positioned to permit application of buss voltage which is the source of energization of the print hammers. When the speed of the characters and the input voltage reach predetermined minimum values, power is applied to a power buss for energizing the print hammers, the application of power being delayed until the synchronizing signal indicates that the print hammers are not in position to be energized. Similarly, if the speed of the characters or the input voltage subsequently falls below the predetermined minimum values, the hammer power buss is synchronously deenergized so as to prevent damage to the printer mechanism.
