Abstract: Apparatus of simple construction that can pass the front portion of a smart card to a card reader, while safeguarding the card reader from vandalism. A gate device (32) whose front end (52) can be pivoted up by the leading edge of the card, is initially prevented from pivoting up by a pair of release members (34, 36) lying within laterally opposite sides of the card path (24). The opposite corners (J, K) of the card leading edge push the release members laterally (L) out of the card path and causes the release members to release the card gate to pivot up.

Abstract: An integral overwrap protective system for a vehicle, e.g., a missile. Includes a filament wound fiber reinforced rubber matrix over a fiber-reinforced composite laminate which forms the vehicle inner skin and a final elastomeric outer coating. The integral overwrap avoids the bonding between vehicle skin and the protective system as in the present systems.

Abstract: A system is disclosed for mounting a vibration producing device onto a spacecraft structure and also for isolating the vibration forces thereof from the structure. The system includes a mount on which the device is securely mounted and inner and outer rings. The rings and mount are concentrically positioned. The system includes a base (secured to the structure) and a set of links which are interconnected by a set of torsion bars which allow and resist relative rotational movement therebetween. The set of links are also rotatably connected to a set of brackets which are rigidly connected to the outer ring. Damped leaf springs interconnect the inner and outer rings and the mount allow relative translational movement therebetween in X and Y directions.

Abstract: An elastomeric prepreg wherein a carrier, whether roving, yarn, broad goods or tape, is impregnated with an uncured elastomeric rubber system which may include the addition of modifiers to enhance the properties of the coating. The prepreg is capable of being spooled and de-spooled for subsequent filament winding or laid up into laminates. In either process no environmental control equipment is required as the volatiles have previously been removed, leaving the elastomer in the generally uncured state.
