Abstract: An aqueous slurry explosive blasting composition comprising an aqueous suspension of water-soluble crystalline oxidising salt consisting predominantly of ammonium nitrate, which salt has been comminuted in a saturated aqueous solution in the presence of a water-soluble crystal-growth inhibiting surfactant having a hydrophobic portion and a hydrophilic portion in its molecule, in intimate admixture with liquid water-immiscible hydrocarbon fuel sensitiser. The surfactant maintains the oxidiser salt in a finely divided state and also ensures that the liquid hydrocarbon remains uniformly distributed throughout the explosive mass as a stable coating of droplets on the salt particles thereby enhancing the explosive sensitivity of the composition. The preferred fuel is diesel oil and preferred surfactants include sodium carboxymethyl cellulose, long chain aliphatic amines, polyacrylic acids, sulphonated nuclear aromatic compounds, sulphonated dyes, sulphonated polymers and long chain alcohol sulphonates and phosphonates.

Abstract: This disclosure addresses resin systems which contain thermosetting materials and thermoplastic modifiers, the resin systems being formed by dispersing particles of thermoplastic solids in the thermosetting materials, the particles being soluble in the resins at temperatures below the resin system gelation temperature. According to this disclosure, the systems are improved by the use of a blend of two types of thermoplastic material-a high glass transition temperature thermoplastic such as a poly(benzophenone-imide) and a high toughness thermoplastic such as a poly(ether-imide). By appropriate adjustment of the relative amounts of these two thermoplastics, resin system properties such as toughness, service temperature, thermal stability and solvent resistance can be adjusted to optimum levels.

Abstract: The present invention relates to an improved seal assembly for sealing between the interior sealing surface of a well housing (12) and the exterior sealing surface of a hanger (16) landed within the well housing. The assembly includes a seal body (20) having a pair of outer lips (74, 76) diverging outwardly for sealing against the housing interior sealing surface and an interior series of annular ridges (8, 2) which have a diameter smaller than the outer diameter of the hanger exterior sealing surface, and an upper energizer (24) and a lower energizer (22) for coacting with said lips to move the lips into sealing position and to store the energy of setting to ensure sealing engagement of the lips. In some forms of the invention the energy is stored by viture of the lips being of a relatively low yield strength material as compared to the energizers which have a higher yield strength. Also structure is provided in some of the forms of the invention to store both radial and axial lip loading forces. <IMAGE>

Abstract: This relates to a color change system to be incorporated in a flexing area of an end panel of a closure. The color change system includes a dark background coating on a flexing portion of the closure end panel to which there is bonded by way of an adhesive such as a varnish, ink or coating a brittle layer which due to the flipping action of the flexing portion of the end panel will fracture. The brittle layer is preferably of a light color and is colored utilizing a fluorescent dye. The combination of the background color and the fluorescent color of the brittle layer produces a first color in the original closure and when the end panel flexes and the brittle layer fractures to not only crack but also tear apart or delaminate from itself, to reflect its own light color much more brilliantly, the color of the color change system drastically changes to indicate tampering. This color change is irreversible. The color change system may also include a message indicia.
