Abstract: The repositioner described includes, in its preferred embodiment, 180-degree repositionable mounting plates with repositionable arms that move up and down, allowing for objects not exceeding 30,000 lbs and which can fit between the mounting plates. Included in the mounting plates are holes for connecting objects that require repositioning. Further included are lifting lugs for safely lifting and/or handling the repositioner as well as shipping ports for safely transporting the repositioner by a variety of methods. Another improvement is a provision for ridged, moisture barrier, non-corrosive cover that attaches to and seals against the repositioner frame. Another improvement involves a provision for repositioning that allows substantial improvement in the speed of repositioning and the safety in which the repositioning is applied to the object within the repositioner mounting plates.

Abstract: The gantry pallet and allweather cover described includes, in its preferred embodiment, many improvements over the currently applied methods of storing, transporting and shipping the U.S. Navy's steam tube Gantry Cranes and accompanying appurtenances. Further included are lifting plates for safely lifting and/or handling and/or safely transporting the gantry pallet and allweather cover by a variety of methods. Another improvement is a provision for ridged, moisture barrier, non-corrosive cover that attaches to and seals against the gantry pallet frame. Another improvement involves a provision for on and off loading that allows substantial improvement in the speed of set-up and the safety in which, but not limited to, the U.S. Navy steam tube Gantry Cranes and accompanying appurtenances is applied to an aircraft carrier's catapult steam tubes.

Abstract: An improved collapsible structure for, but not limited to, the safety of the launch valve voyage repair team while engaging in removal, installation or performing routine maintenance of the launch valve and the water break assembly in all weather conditions. It is quickly installed or removed and serves as a means to protect the launch tube valve and the water break assembly in all weather conditions while said valve and assembly are disassembled.

Abstract: The subject invention pertains to an improved air-operated hammer which can utilize a pressurized air reservoir located near a pressurized air entrance of the hammer. This pressurized air reservoir can continue to receive pressurized air even when the hammerhead is failing and, preferably, can enable pressurized, air to enter the hammer at, a faster rate than the hammer's external compressed-air source can supply. The subject invention can utilize a compressed-air source with a lower flow rate and/or lower pressure in comparison with a typical air-operated hammer, in order to achieve the same hammer performance. Alternatively, the subject invention can utilize an equivalent compressed-air source in comparison with a typical air-operated hammer, in order to achieve superior hammer performance, for example shorter time periods to raise the hammer head leading to move hammer drops per time.
