    摘要: A method for forming a joining profile in a structural member comprises providing an assembly having a base member, a forming body and a pair of side anvils having profiles formed therewithin. The method further comprises mounting the structural member on the base member, advancing the forming body toward the structural member such that the structural member is clamped to the base member, urging the side anvils toward flanges of the structural member, forming a profile in each of the flanges, and engaging protrusions of the side anvils with the web such that opposing portions of the web are forced upwardly by the protrusions at locations adjacent to each one of the flange profiles in order to accommodate formation of the flange profiles in the structural member. Formation of the joining profiles in the structural members allows for detachable engagement thereof with another member having a corresponding mating profile.

    摘要: A more IM compliant energetics train for a grenade fuze or a detonator includes an explosive charge containing PBXN-5 and a first charge containing PBX-9407 disposed adjacent to the PBXN-5 explosive charge. A flying disc is disposed adjacent to the first charge of PBX-9407. A barrel has one end disposed adjacent to the flying disc and an opposite end disposed adjacent to a second charge containing PBX-9407. Detonation of the first charge containing PBX-9407 causes the flying disc to accelerate through the barrel, impact the second charge containing PBX-9407 and detonate the second charge containing PBX-9407.

    摘要: An activated porous phosphorus/vanadium oxide catalyst adapted for the catalytic oxidation of a hydrocarbon to produce a carboxylic acid anhydride. The catalyst comprises shaped bodies having a B.E.T. surface area of at least about 15 m.sup.2 /g, an average vanadium oxidation state of between about 4.0 and about 4.5, a total pore volume of at least about 0.15 cc/g, a normalized apparent shaped body density of between about 1.25 and about 2.0 g/cc, and a crush strength of at least about 4 pounds. At least about 5% of the pore volume of the catalyst is constituted of pores having a diameter of at least about 0.8 microns, and at least about 4% of the pore volume is constituted of pores having a diameter of at least about 10 microns. The catalyst is prepared by mixing a particulate phosphorus/vanadium oxide precursor with a pore modification agent to produce a modified catalyst precursor composition, forming the modified precursor composition into a predetermined shape, and removing the pore modification agent substantially at a temperature below 300.degree. C.
