Patent number: 8986473Abstract: The invention is a composition for a high burning-rate solid rocket propellant, where the composition includes a binder compounded with a soluble energetic additive; a metallic fuel; and an oxidative fuel. The resulting composition has a tactical Class 1.3 hazard rating, and a linear regression rate that is substantially equivalent to a tactical Class 1.1 hazard rating obtainable using solid rocket propellants. The composition may include a heat-conducting element, a plasticizer, a curing component, a combustion catalyst, and curing catalyst.Type: GrantFiled: September 3, 2008Date of Patent: March 24, 2015Assignee: The United States of America as represented by the Secretary of the NavyInventors: John M.

Patent number: 6783613Abstract: The present invention is a modified HFPB polymer for use in propellants and explosives that is chemically degradable and also is compatible with commonly used energetic plasticizers. The HFPB polymer of the present invention contains ester linkages formed in the backbone of the polymer from a dicarboxylic acid containing either oxymeythylene or oxyethylene moeities. The ester and ether linkages change the polarity of the polybutadiene to make it compatible with polar energetic plasticizers. The ester linkages along with either oxymethylene or oxyethylene moeities make the polymer degradable to basic solutions while still maintaining the structural integrity necessary for a polybutadiene type binder.Type: GrantFiled: April 4, 2002Date of Patent: August 31, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Robert C. Gill, Horst G. Adolph

Patent number: 6723190Abstract: A communication system comprises an input-output processor IOP (11) coupled to a plurality of network devices (10) and a protocol processor PP (12), both processors being coupled to a common memory (15). Memory access control means (16) resolves competition between the processors for memory access. Normally, if one of the two processors is accessing the memory, the memory control unit (16) allows that access to be completed before allowing the other processor to access the memory. But if data loss in a network device is imminent, the IOP, is granted a higher priority memory access, the memory access controller aborts (interrupts) any memory access by the PP, allowing the IOP to access the memory immediately.Type: GrantFiled: October 27, 2000Date of Patent: April 20, 2004Assignee: The United States of America as represented by the Secretary of the NavyInventors: Robert C. Gill, Carl Gotzmer, Pamela Carpenter, Eric Schlegel
