Abstract: A loader includes a sleeve support which will carry in a raised position a lightweight open-centered sleeve, of the type which is capable of holding a plurality of automobiles. An automobile support, capable of carrying the automobiles which will comprise one level when loaded into the sleeve, is located below the sleeve. A lifting device moves the sleeve support and the automobile support together to insert the automobiles into the sleeve from its bottom. Latching mechanisms which attach the automobiles to the sleeve are movable between loading positions, where the automobiles can be inserted past them, and latching positions where they will engage the automobiles' tires. The loader is capable of removing the sleeves from cargo containers for loading and/or unloading and then placing them back into the containers when this procedure is completed. The apparatus also is capable of folding the sleeves to their collapsed position and of expanding them to their erected position.

Abstract: A transloader provides means and method for adjusting multiple chains in an array for uniform tensioning. The transloader is mounted adjacent a reference member with chain adjustment rods passing through respective spring assemblies in a spring block. The central adjustment rod is adjusted to position the spring block with respect to the reference member and the remaining adjustment rods adjusted to position respective spring followers relative to the spring block thereby providing uniform tension on all chains.

Abstract: A control valve system and method are disclosed for blowout preventers having an actuating piston for actuating the closing of the blowout preventer whereby the piston has an opening side and a closing side. The control valve system and method include a means for selectively directing fluid from the opening side of the actuating piston to the closing side of the actuating piston in order to reduce the fluid requirements for closing the blowout preventer and reduce installed horsepower requirements thereby.
