Abstract: A remote control mirror, comprising a mirror support, a base having a projection fixed thereto and extending therefrom. The mirror support has a groove into which the projection extends. The groove has a bottom which is arcuate both longitudinally and transversely of the groove. The curvature of the groove longitudinally is greater than the curvature of the groove transversely. In one form, the projection has at least two contact areas engaging the groove, which have a lesser extends of curvature than the groove in a direction transversely of the groove. In another form, the two areas form a part of the projection.

Abstract: This disclosure describes a self locking drive system for rotating the plugs on the head of a nuclear reactor which is able to restrain plug motion if a seismic event should occur during reactor refueling. A servomotor is engaged via a gear train and a bull gear to the plug. Connected to the gear train is a feedback control system which allows the motor to rotate the plug to predetermined locations for refueling of the reactor. The gear train contains a self locking double enveloping worm gear set. The worm gear set is utilized for its self locking nature to prevent unwanted rotation of the plugs as the result of an earthquake. The double enveloping type is used because its unique contour spreads the load across several teeth providing added strength and allowing the use of a conventional size worm.

Abstract: A method of loading a cell of a vertical launching system missile launcher n a combatant ship with a canistered missile from a supply ship wherein the canistered missile is transferred from the supply ship to a fixed guide on the deck of the combatant ship, upended in the guide, moved away to a position over the cell of the missile launcher, and then lowered into the cell.
