    Abstract: A plurality of type carriers having spaced type characters and stop teeth thereon are yieldably driven past a printing station and are arrested by engagement of electromagnetically controlled stop pawls with selected ones of the stop teeth. The type characters and stop teeth on certain of the type carriers are staggered relative to the type characters and stop teeth on other type carriers to reduce the mechanical ''''break-away'''' load and the electrical load.

    Abstract translation: 具有间隔型字符和多个停止齿的多种类型的载体可以可靠地被驱动通过印刷站，并且通过电磁控制的止动爪与所选择的止动齿的接合来阻止。 某些类型载体上的类型字符和停止齿相对于类型字符交错，并在其他类型载体上停止齿，以减少机械“脱离”负载和电负载。

    Abstract: A cyclically operable high speed data printer comprising a plurality of type wheels supported and yieldably driven by a drive shaft, each wheel having character position stops and a home stop. The drive shaft is driven through two revolutions in the same direction for each cycle. During the first revolution, stop devices are spring actuated at different times to engage certain of the character position stops to arrest the type wheels in different type printing positions. Printing occurs after the first revolution, and during the second revolution, the stop devices are positioned to arrest the home stops whereby to locate the wheels in their home positions.

    Abstract: A high speed solenoid operated punch for paper tape or the like in which a relatively weak spring is provided to normally hold the punch in retracted position and to take up clearances in the punch linkage. A second stiffer, cantilever type spring is engaged by the punch linkage only after the punch has partially sheared through the tape and, finally, a much stiffer cantilever type spring is engaged after the punch passes completely through the tape to arrest the punch and to catapult the same back to its retracted position, aided by the second spring.

    Abstract: A checkwriter incorporating an accumulator and differentially settable sectors for entering amounts to be printed on checks and for subtracting such amounts from the accumulator as well as for adding into the accumulator amounts representing deposits in the user''s bank account. The checkwriter is automatically locked up when an amount is overdrawn from the accumulator or when an amount greater than a predetermined amount is entered. The checkwriter also incorporates control means which are normally set to cause subtract operations but which may be selectively set to cause an add operation and which are automatically returned to subtract controlling condition following an add operation.
