Abstract: A reader for punched document cards having a slide for carrying a document card and movable manually against the action of a spring to put the document card in a pre-reading position, a governor for controlling the motion of the slide and document card in a return movement generated by the spring and a series of switches actuated by the punchings as the card returns under spring action to an initial position. One way clutch mechanism is associated with the governor so that the initial movement of the slide and document card may not be impeded by governor action. A latch operated by the slide is effective to prevent movement of the slide manually out of its initial position with no card in the reader, and the latch is negated in its action by a card in position so that the slide and card may be moved out of initial position.
Abstract translation: 一种用于打印的文件卡的读取器，具有用于携带文件卡的滑动件，并且能够手动地抵抗弹簧的动作移动，以将文档卡放置在预读位置;调节器，用于控制幻灯片和文档卡在回报中的运动 由弹簧产生的运动以及当卡片在弹簧作用下返回到初始位置时由冲头致动的一系列开关。 单向离合器机构与调速器相关联，使得滑块和文件卡的初始运动可能不受调节器动作的阻碍。 由滑块操作的闩锁有效地防止滑块在读取器中没有卡片时手动移动到其初始位置之外，并且闩锁在其动作中被卡在位置被否定，使得滑块和卡可以移出 的初始位置。

Abstract: An enclosure for a rigid disk data file is shown which includes a base casting (6) and a cover (24) that interface along a planar surface that is not perpendicular to the axis of the spindle supporting the data disks (8). The base casting (6) at one side extends axially along the disk stack and has the transducer positioning actuators mounted through openings therein. At the opposite side, the disk stack is fully exposed to permit easy access to the disk surface for procedures such as servo writing during manufacture of the drive. This structure makes possible concurrent operation of the product heads and servo writing heads.

Abstract: The magnetic head actuator includes a substantially totally enclosed self-shielding voice coil linear motor which includes a continuous, cylindrical permanent magnet (18) of flexible material which is sealed against the inner cylindrical wall of the outer core (11) by a flared copper sleeve (29) that also serves as a non-magnetic, conductive shorted turn to reduce instantaneous inductance of the drive coil (35). An annular reluctance gap in the outer core provides symmetrical distribution of the permanent magnet flux.
