  • Process for producing and processing multi-component mixtures on the basis of reaction plastics
    Patent number: 5077080
    Abstract: A process for producing and processing multicomponent mixtures on the basis of reaction plastics provides that the liquid mixture is cooled off to a temperature that allows virtually dry further processing. This is done in that the cooled reaction plastic mixture is shaped as a solid piece from which material is rubbed off while it is applied onto a surface to be coated. The rubbed off material melts on the surface to be coated and hardens within a short period of time.

  • Process for hardening ballasts and other heaped structures
    Patent number: 4985276
    Abstract: The process for hardening ballasts and other heaped structures calls for an adhesive, which is pourable at ambient temperatures, to first be transformed into the solid state by means of cooling. Then, the application of the liquid adhesive onto the heaped structure is time-dosed by the thawing of the cooled adhesive.

  • Floats to be used pairwise to walk on water
    Patent number: 4731039
    Abstract: An elongate float to walk on water with another such float is provided with a foot holder. The foot holder is mounted in a transverse direction such that the buoyancy force on the inside edge of the float relative to the other float is greater than the buoyancy force on the outside edge.
