Abstract: A fire extinguisher comprises an elongated tube. The elongated tube has a pressure-tight, thermoplastic exterior tubular wall and an axially parallel, flame resistant inner wall. The inner tubular wall defines a chamber and the wall has ports through the wall at regular intervals along the length and around the circumference providing fluid communication between the chamber and the exterior tubular wall for a quantity of fire extinguishing fluid under pressure in the chamber. The thermoplastic exterior wall ruptures on contact with flame. The inner tubular wall remains intact and fire extinguishing agent discharges through the ports to extinguish the fire. The apparatus is actuated by contact with flame and requires no actuation by the vehicle crew.

Abstract: Many embodiments of the present invention are imbued with both sight-facilitative and touch-facilitative characteristics. The invention's unitary resinous matrix configuration encompasses, in the form of small discrete bodies, three genres (luminescent, reflective, retroreflective) of visually enhancing material along with tactilely enhancing material. The retroreflective and abrasive bodies partially project at a light-exposable surface of the resinous matrix material; the luminescent and reflective (diffuse and/or specular) bodies lie beneath the light-exposable surface. The luminescent, reflective and retroreflective bodies are complementarily and cumulatively effective; in particular, they versatilely afford increased visibility at practically all angular lines of sight as well as under practically all deficient illuminative conditions. The abrasive bodies afford vehicular skid prevention, surefootedness and the capability to manually and/or pedally “feel one's way” to safety.

Abstract: A sealant in its liquid phase is placed between attachment portions of paint coated metallic parts for subsequent in-place solidification into a gasket for both sealing and permanent bonding purposes. The attachment portions are then interconnected by screws extending through the gasket to increase its bonding strength.
