Abstract: A self-contained, mobile precursor dispensing system causes foam precursors to flow from precursor vessels via hoses to a dispensing gun in a required volumetric ratio. Instead of requiring the precursors to flow through a volumetric proportioner, volumetric flow meters, or flow control valves, effective lengths of the hose are configured to cause the precursors to flow in the required volumetric ratio. The effective hose lengths can be configured by selecting hoses having different inner diameters, different physical lengths, and/or different degrees of internal roughness. A compound hose having a desired effective length can be formed by joining together a plurality of hose segments of differing physical properties. The precursor flow rates can be measured by dispensing each precursor separately under identical conditions and weighing the dispensed precursor quantities. Initial precursor volumes and gas-filled head spaces in the vessels can be proportionate to the required volumetric ratio.

Abstract: A system for processing scrap material that includes a variable-power electromagnetic drum separator wherein shredded scrap material is placed in free fall at a position proximate the electromagnetic drum separator. A first fraction of the scrap material is attracted to the electromagnetic drum separator and is carried under the rotational axis of the electromagnetic drum separator thereby separating the first fraction of material from a second fraction of the material which continues to free fall and wherein the first fraction is a low-copper ferrous material with the second fraction having a higher non-ferrous content than the first fraction. A magnetic drum separator may be positioned upstream of the variable-power electromagnetic drum separator and be used to separate non-ferrous materials. The variable-power electromagnetic drum separator may be adjusted so that the second fraction includes some ferrous material. A robotic picker may be used to remove undesirable materials from the second fraction.

Abstract: Carbon-neutral fuels are produced from aragonite in a solar thermal decomposition process in which the carbon dioxide generated from the aragonite is catalytically converted to methane, ethanol, or Fischer-Tropsch liquids. Advantageously, heat from the aragonite production can be recovered and used in downstream processes to thereby minimize the carbon footprint of the fuel production.
