Abstract: A random selection apparatus for a game is provided. The apparatus includes a container having a chamber and a tapering throat. A magnetic object is housed within the chamber and is held captive therein by the tapering throat. The magnetic object includes at least one pair of magnetically polarized opposing faces. A magnetically polarized elongate member is provided which is sufficiently narrow for insertion into the chamber through the throat. Upon insertion, a polarized end of the elongate member magnetically interacts with the magnetic object in the chamber and, upon removal from the chamber, draws the magnetic object to the throat of the container, where the object is temporarily lodged, with one of the two opposing faces exposed for view. In this manner, one of the opposing faces of the amgnetic object is randomly presented for view at the throat of the container. Games are provided in which the apparatus is used.

Abstract: A device is disclosed for restraining lateral movement of large underwater equipment, such as a blowout preventer (BOP) stack for use on subsea wells, when retrieving or running such equipment through the well of a floating vessel. A plurality of rollers are angularly positioned about the well, each roller being capable of rolling longitudinally (vertically) along the equipment. Each roller is connected to shock absorbers for cushioning lateral movement of the equipment and to a piston cylinder for moving each roller toward and away from the equipment.
