Abstract: A disposable ampoule opener, in combination with ampoule, is disclosed, which may include a first housing section having a substantially convex outer surface and a substantially concave inner surface shaped to receive at least a portion of the ampoule and a second housing section having a substantially convex outer surface shaped to receive at least a portion of the ampoule, wherein the ampoule has a lower liquid portion capable of containing liquid and an upper tip portion that is narrower in diameter than the lower liquid portion, the ampoule further having a neck portion disposed between the lower liquid portion and the upper tip portion, and wherein the second housing section is coupled to the first housing section, and which may also include ribs along one of the inner concave surfaces and ridges alone one of the outer convex surfaces.
Abstract: The installation and use of abrasion and corrosion resistant polyolefin and polyolefin blend liners in the production or injection string of a well is shown. The lining is employed for the principal purpose of reducing wear or corrosion on the tubing string or wear on the associated production equipment. In a preferred embodiment of the invention, the polymer liner is characterized by polypropylene material, which is abrasion resistant and which has a coefficient of friction that is lower that the coefficient of friction of metal tubing. Also, disclosed herein are tubular goods and tubular good liners which decrease or eliminate friction and mechanical wear and decrease or eliminate chemical corrosion to the walls of the tubular good. The liners may include a diffusion barrier, an adhesive, and a friction and wear resistant layer.
Abstract: Disclosed are (1) a thermoplastic elastomeric film comprised of an elastomeric arene-diene block copolymer and particular ethylene/&bgr;-olefin copolymers having low ethylene crystallinity and (2) the process of preparing films thereof. The disclosed films have superior strength and elasticity characteristics which render them particularly useful in apparel and healthcare items such as disposable diapers.
