A medium for irreversible information storage by locally changing the electrical conductivity of a carrier whose discrete areas of electrical conductivity have been produced by means of polymeric systems which contain conjugated double bonds and are formed by a field-chemical reaction, and a method for carrying out this information storage.

The horizontal orientation of a rocket moving in a liquid is achieved by an arrangement in which a magnet is attached to the rocket body. The axis of the rocket and the magnetic axis of the magnet form an azimuthal angle .alpha., which determines the direction of the rocket relative to the geomagnetic meridian.

A process for gaining access to the coal of very deep seams, and for extracting this coal with the aid of a conveying liquid, which is fed to the seams via boreholes and is thence brought back again to the surface with coal which has been detached, wherein agents for detaching and breaking up the coal are admixed to the liquid.

An improved method of removing heat from polymerization reactions of normally gaseous monomers in the gas phase comprising feeding the monomer in liquid form to a polymerization zone, immediately after entering said zone, removing a portion of said gaseous monomer from the polymerization zone, liquefying said portion of monomer by cooling it at the same pressure as that prevailing in the polymerization zone, recycling the liquefied monomer to the polymerization zone together with fresh monomer in liquid form and causing said liquid monomer to change to the gaseous form immediately after entering said zone. The improvement consists in not only condensing the monomer outside the polymerization zone but also storing the same, in keeping the temperature in the polymerization zone constant by regulating the rate at which liquid monomer is fed to the zone, and in keeping the temperature and pressure in the polymerization zone within limits conducive to the gaseous state of the monomer.
