Abstract: A dry process for cold briquetting of metallurgical dusts, including converter steel dust, to provide transportable briquettes which do not give off dust, including the steps of admixing metallurgical dust and at least one basic additive selected from the group consisting of lime, dolomite, magnetite, dunite, olivine and bauxite, in burnt or unburnt form, to provide a mixture, and forming the mixture into briquettes at pressures in excess of 10,000 bar and at ambient temperature.

Abstract: An electromagnetic fuel saving device for internal combustion engines. The device includes two electromagnetic assemblies and two connectors. Each electromagnetic assembly includes a coil, a spool, an insulating tape, a casing, a core, two studs, and two terminals. The coil is wound around the spool and is covered by the insulating tape. The casing encloses the coil, the spool, and the insulating tape. The core is pivotally mounted within the spool cylinder and extends on either side of the spool. A stud is connected to each end portion of the core. The terminals are connected to the coil and are adapted to be used to operatively connect the coil to a battery. Two electromagnetic assemblies are installed on a fuel line in opposing relationship by aligning them so that they contact the periphery of the fuel line, by connecting them with the two connectors, and by operatively connecting them in parallel to a 12 volt direct current circuit. When so installed, there is a gap between the opposing studs.
