Application for reissue Oct. 25, 1973, Ser. No. 409,747 InL CI. B63b 35/08 a. 114—.5 R 15 Claims A marine well drilling platform or the like having legs extending to the sea floor is protected from ice floes by comminuting devices at the water line for breaking the ice anl thereby preventing crushing or overturning of the platform. The comminuting devices employ high velocity impacts against the ice to cause its fracture into chips as distinguished from cutting action. Rapidly rotating or re- ciprocating mechanisms with large "teeth" for making im- pact engagement with the ice are employed in separate embodiments. Comminuting devices mounted for sweep- ing adjacent a mooring buoy in one embodiment open a path through an ice floe for protecting the buoy and a ship moored at the buoy.

Re. 28,966 SYSTEM AND BARRIER FOR CONTAINING AN OIL SPILL Thomas Nicholas Blockwick, McLean, Va., assignor to Ocean Systems, Inc., Rsston, Va. Original No. 3,708,982, dated Jan. 9, 1973. Ser. No. 79,997, Oct. 21. 1970. Application for reissue Jan. 24, 1974, Ser. No. 436,146 Inl. CL E02b 15/0-1 Ci. 61—1 F 19 Claims A system for containing an oil spill comprising a plu- rality of barrier modules each composed of a compos- ite structure having a buoyant upper section .and a water absorbing lower section which represents con- currently the sole ballast for said upper section and the subsurface barrier for the module.
