Abstract: A tool for pulling flexible hose includes a longitudinal arm with a handle at one end and a hook at the other end. The hook includes first and second hook ends spaced from each other by a distance at least equal to the diameter of the hose to be pulled, and first and second support surfaces near the respective first and second hook ends. The first and second support surfaces engage the outer surface of the hose as the hose is being pulled. A protrusion near either the first hook end or the second hook end retains the length of hose so as not to slide outward of the first and second hook ends while the hose is being pulled.

Abstract: A heat detection apparatus comprising a display face having a protruding member extending therefrom disposed in a fixed frame means and connected to a tension means in a tensioned mode, said protruding member and display face maintained in a first position under tension by a solid retention means disposed with the distal end of said protruding member in communication with said protruding member and frame means with said retention means meltable at an elevated temperature, and wherein melting of said retention means permits relaxation of said tension means resulting in said protruding member and display face moving to a second position under relaxation, and further wherein said display face displays a first indicator of non-elevated temperature in the first position and a second indicator of elevated temperature in the second position.
