Abstract: A pressure sensitive adhesive composition comprising (a) a block copolymer composition comprising (i) a first component having a configuration of A-B, and (ii) a second component having a configuration of A-B-(B-A)n where n ranges from 1 to 20, wherein A is an alkenyl aromatic or arene hydrocarbon polymer and B is polybutadiene, and wherein the first component is present in an amount ranging from about 40 weight % to about 95 weight % based on a total weight of the block copolymer composition; (b) a polyphenylene oxide resin; and (c) a tackifier resin compatible with B.
Abstract: The present invention comprises a module for a surgical driver of the type having a handle and a barrel with an axis. The module comprises a releasable attachment mechanism for releasably attaching the module to the surgical driver, a tool mounting mechanism for releasably receiving an orthopedic surgical tool, and a rotational orientation mechanism for orienting the tool mounting mechanism in a plurality of angular positions about an axis of the barrel. The device includes a releasable locking mechanism for releasably locking the rotational orientation mechanism in one of a plurality of discrete angular positions about the axis of the barrel. The releasable locking mechanism has a locking member movable between lock and release positions. A spring biases the locking mechanism toward the lock position. The novel locking mechanism of the present invention may also be used in non-modular devices.

Abstract: A water-base endothermic fire protective material comprising a heat curable thermosetting resin, inorganic fibers, an endothermic inorganic filler, and thermoplastic binder resin is disclosed. The material can vary in viscosity from a putty that is moldable or trowelable into place to a thin paste that can be sprayed to form a flexible and stable fire stop seal or coating. The material with essentially no shrinkage retains strength and adhesion qualities before and after exposure to fire and retains superior resistance to the impact, erosion, and cooling effects of a hose stream used to combat a fire.
