Abstract: A magnetic card transport which includes three drive rollers. A forward drive roller for driving the magnetic card toward the entry throat for recording character by character and for ejecting the card from the transport; a reverse drive roller for positioning the card in an opposite direction for read checking a previously recorded character; and a high speed reverse drive roller for positioning the card at the beginning of a track during initial entry from the throat and from the end of a previously recorded track. The three drive rollers continuously rotate beneath the card and the card is caused to move by application of a pinch roller to the card to press it into rolling contact with its associated drive roller. A fixed guide rail is provided and the card is biased against the fixed guide rail by means of guide springs. Further, to prevent misalignment of the card during reading and writing the pinch rollers associated with the forward and reverse drive rollers are canted such that the resultant moments of force are in a direction to bias the card against the fixed drive rail. The entry/exit throat of the card transport, the drive rollers and the magnetic head are located such that optimum utilization of the recording area on the card is accomplished. In addition, a dual card switch located near the innermost extremity of the card bed is positioned such that it is not contracted during normal movement of the card, but in the event an operator attempts to insert another card and thereby force the original card further into the machine and out from under the pinch rollers, the switch is operative to signal the logic that an eject cycle must be entered into and the mechanical spring of the switch causes the card which tripped the switch to be flipped back into engagement with the drive rollers such that that card is also ejected.

Abstract: FAST ACTING TWO-WAY VALVE A valve assembly having a small volume cavity formed therein which communicates with two valves, one of which is closed completely before the other one is opened and vice versa. An actuating mechanism holds a valving member in one of the valves in an opened condition to thereby maintain a fluidic path through the one valve and the cavity. The other valving member at this time lies in a closed position preventing communication between this valve and the cavity. The actuating mechanism when actuated moves away from the valving member in the open valve allowing the open valve to close completely. The fluidic path through the one valve is thereby broken. A second fluidic path is made when the actuating mechanism moves the other valving member to an opened position.

Abstract: An ink jet printing apparatus has provision for both line printing and character-by-character printing. A directionally oriented grating and associated circuitry is provided to maintain a record of character and ink drop printing locations. Also, provision is made for over-shooting the printhead some distance past each character printed during an incremental mode and for stopping the printhead to enable better visibility of the character just printed. Upon printing of the next character, the printhead first moves to the left a sufficient distance to get past the character box to be printed and sweeps to the right with the overshoot and stopping as before.
