Abstract

800,729. Soil stabilization. "FORAKY" S.A. May 8, 1957 [April 10, 1957], No. 14626?57. Class 68(1) Cold liquid is passed down through a tube 1 positioned within a second tube 2 closed at the lower end and emerges into the tube 2 to pass upwards therethrough before entering a third tube 3 extending upwards out through the top of the tube 2. The tubes 1 and 2 are slidable in the cap 6 closing the tube 2 so that the freezing zone defined by the levels of the lower ends of the tubes 1 and 2 is of variable length. Specification 726,877 is referred to.
