Abstract: An improved apparatus for winding a water-ski rope on a reel in a short period of time by utilizing a winding device containing a spring which becomes wound up as the rope is progressively unwound from the reel. When the load is removed from the end of the rope, the spring returns to its original non-stress condition causing the rope to be wound up on the reel.

Abstract: A process for the manufacture of a rigid foam out of a slurry containing an alkali silicate, or foaming agent, a substance which produces a gradual reaction with the alkali silicate, and other additives. It is essential that dinitrosopentamethylenetetramine be included in the slurried mixture. Such an undesired decomposition residuum as formaldehyde that may be produced by this compound is removable either by the combined use of a ureal substance or by an additional heat treatment of the slurry. To be turned into a rigid foam, this slurry is agitated at a temperature less than the boiling point thereof, succeedingly foamed and hardened, and dried.
