Abstract: A device (10) adapted to seat on spaced, parallel rail surfaces of a card rack having a plurality of printed circuit cards (14), seated therein, each being characterized by a card rail (22) extended along the upper side edge thereof. The device includes a cylindrical bar (24) adapted to seat on the rail surfaces of the rack, a blade (42) projected radially from the bar adapted to be received beneath a card rail and a handle (40) affixed to the bar in diametric opposition to the blade for facilitating manipulation of the blade for lifting the card at its rail sufficiently for unplugging the card preparatory to the removal thereof.

Abstract: A bracket for an electrical servo actuator wherein said servo actuator (10) is mounted on a support arm (12) which is allowed to pivot on a bolt (14) through a fixed mounting bracket (16). The actuator is pivotally connected to the end of the support arm by a bolt (18) which has an extension (24) allowed to pass through a slot (26) in the fixed mounting bracket. An actuator rod (34) extends from the servo actuator to a crank arm (32) which turns a control shaft (36). A short linear thrust of the rod pivots the crank arm through about 90.degree. for full-on control with the rod contracted into the servo actuator, and full-off control when the rod is extended from the actuator. A spring (28) is connected at one end to the fixed mounting bracket and at the other end to the extension (24) of the bolt (18) connecting the actuator to the support arm.
