Abstract:

A spacecraft specifically adapted for launch from the space shuttle by means of a cradle having locking and ejection mechanisms mounted therein. The cradle fastens into the payload bay of the space shuttle and returns therewith for reuse in subsequent launches. The spacecraft mounts at three points to the cradle, and the cradle mounts at three points to the shuttle such that a plane through the attachment points passes through the roll axis of the spacecraft at approximately the center of mass thereof. The cradle utilizes the truss structure of the spacecraft to produce the required stiffness by providing a structural tie between the two ends and the bottom of the cradle. At launch, the spacecraft is ejected with both linear and angular momentum, the spin providing gyroscopic stability. The locking mechanisms in the cradle can be remotely controlled to relock the spacecraft to the cradle in the event of an unsuccessful deployment attempt. The spacecraft includes a safety circuit employing acceleration sensing switches which sense spin-up of the spacecraft and prevent premature ignition of the perigee boost motor.

Abstract:

The gun storage and rapid removal mount of this invention is for securely retaining a shotgun or the like against unauthorized removal with the mount providing for rapid removal by authorized persons. It comprises a trigger guard cup and a forward lock clamp. The lock clamp engages the barrel and a magazine tube just forward of the shotgun receiver to prevent forward motion of the shotgun in the mount. The trigger guard cup prevents rearward motion. The lock clamp is both lock- and spring-retained. When its lock is released, the gun can be rotated out of the clamp against spring force. The spring also permits reinsertion of the shotgun into position against the spring force.
