Abstract: Carbon nanotube reinforced polymers include a polymer and carbon nanotubes reinforcing the polymer. The carbon nanotube reinforced polymer exhibits a conductivity percolation threshold of less than 106 ?/cm at a carbon nanotube content of 1.5 wt. % and less. The polymer may be selected from a polyamide or a polystyrene based polymer. In certain embodiments, the carbon nanotube content is between 0.1 to 1.5 wt. %, and the reinforced polymer will have a percolation threshold at a carbon nanotube content of less than 0.5 wt. %.

Abstract: The invention relates to a plunger stopper for syringe barrels, the plunger stopper having one or more constrictions and a first and a second end, wherein at least the first end of the plunger stopper is of tapered design. In a first particular embodiment, at least the first end is of conically tapered design. In a further particular embodiment, at least one end is provided with a bore. However, both ends can also be of conically tapered design and can be provided with a bore.

Abstract: An improved blind label is disclosed which includes a combination of open text and blinded text arrayed upon adhesive-backed label stock in an arrangement in which the label is divided into two sections joined by a tearable separation zone. In this improved label the first section is permanently affixable to the container to be labeled by its adhesive. The second section, carrying at least a portion of the blinded text, is strippably affixable to the container or to the first section by means of its adhesive backing. In certain embodiments, the blinding is accomplished by means of an opaque overcovering strippably adhered over the text with tamper-evident metallic layers being preferred overcoverings. An automatic labeling machine-compatible blind-label feedstock is also disclosed.
