Abstract: A process for temperature treating a granular material such as sand by the use of ambient air moving through the material, as it drops under gravity from a screen, at a wind velocity high enough to invoke forced convection as an aid in accomplishing the temperature controlling function.

Abstract: A portable tool for compressing a fitting on a high pressure hose comprising identical forged and machined parts that are held in alignment by parallelly positioned bolts that extend therethrough. The parts moved toward each other when a hammer or the like is applied to the outside surface of one of the parts. The parts have aligned mating surfaces each defining a die in their opposed surfaces for compressing a fitting to a hose when the hammer or like force is applied thereto. Shims are used to reduce the size of each die so that the tool can be used with an assortment of hose fittings on a variety of hose sizes.
