Abstract: An uplift-resisting assembly, connected to a top of a tubular member of a height adjustable structural column, acts to transfer load, particularly uplift loads imposed on the structure to which the column supports, therethrough and into the tubular member. The housing of the assembly is connected to the tubular member, which is connected to a base such as a footing. A threaded rod extends through the housing and into the tubular member. A top plate, connectable to a structure above is attached to the top of the threaded rod. An adjustment nut, threaded onto the threaded rod for adjusting the height of the column is sandwiched between the top of the housing and the top of the tubular member. The adjustment nut bears on the tubular member in compression and bears on the top of the housing during uplift, the uplift being transferred via the housing into the tubular member.

Abstract: An apparatus and a method for melting block sulphur employ a heating element pivotally mounted on a carriage on a trailer. The heating element is pivoted from a collapsed, transport position to an upright position, and a counterweight force is applied to the carriage to advance the heating element in a direction at least approximately parallel to the ground towards the sulphur.
