Abstract: A pipe insulation coupling for supporting a pipe and for coupling adjacent ends of pipe insulation tubing is disclosed. The pipe insulation coupling comprises an outer tube wall, a planar interior wall and a sealing mechanism. The outer tube wall extends along a longitudinal axis. The outer tube wall is split longitudinally from a first end thereof to a second end thereof to define a first body portion and a second body portion. The planar interior wall extends inwardly from the outer tube wall transverse to the longitudinal axis. The planar interior wall includes a center bore for receiving the pipe. The planar interior wall provides an abutment for the adjacent ends of the pipe insulation tubing. The sealing mechanism extends longitudinally between the first and second ends of the outer tube wall for securing the first and second body portions together.

Abstract: A self-propelled emergency stretcher includes an elongate frame having a set of wheels a track drive unit mounted thereto. The set of wheels includes first wheels at a front end of the frame and second wheels at a rear end of the frame, and the track drive unit is mounted between the first wheels and the second wheels.

Abstract: A pipe support is coupled to an elongated channel for receiving and supporting a pipe. The channel includes a base and a pair of spaced apart sidewalls extending from the base to a top plate. A flange projects downwardly from each top plate towards the base and defines a slot therebetween. The pipe support includes a body portion extending axially between opposite ends and having an inner surface and an outer surface. The body portion includes a generally arcuate bottom floor and a pair of spaced apart sidewalls projecting generally upwardly from the bottom floor.
